## OpenBlock Enterprise Wallet Overview

Welcome to the OpenBlock Enterprise Wallet! Designed for teams and businesses, OpenBlock enterprise wallet offers enhanced security, flexibility, and control over your organization’s digital assets.

This article will detail the features of the OpenBlock Enterprise Wallet, including team roles, 2-2 TSS key management, MPC off-chain multi-signature, customizable approval workflows, sub-wallet management, and a flexible API library.

## Team Roles
### Administrator
Administrators are the core roles in the OpenBlock Enterprise Wallet, responsible for the overall management and configuration of the wallet. The permissions and responsibilities of administrators include:

**Inviting and Managing Members**: Administrators can invite new members to join the wallet team and manage the permissions and roles of existing members.
**Configuring Wallet Settings**: This includes setting multi-signature rules, customizable approval workflows, and security strategies. Administrators can flexibly adjust various configurations of the wallet according to enterprise needs.
**Approving and Signing Transactions**: Administrators have the authority to approve and sign transactions, ensuring that each transaction meets the enterprise's security and compliance requirements.
**Monitoring and Auditing**: Administrators can monitor all activities within the wallet in real-time.

The OpenBlock Enterprise Wallet allows up to six administrators, ensuring the decentralization and redundancy of management functions to prevent single points of failure and misuse of permissions.

## Member Role
Members are the operational roles in the OpenBlock Enterprise Wallet, responsible for daily digital asset management and operations. The permissions and responsibilities of members include:

**Initiating Transactions**: Members can initiate transaction requests, but they require the approval and signature of an administrator to take effect. This ensures the security and compliance of transactions.
**Viewing Transaction Records**: Members can view the wallet's transaction records, understand account balances, and track fund flows, facilitating daily management and operations.
**Participating in Multi-Signature Approvals**: Under multi-signature rules, some members may be assigned signing permissions to participate in the multi-signature process, ensuring the security and decentralized management of transactions.

The OpenBlock Enterprise Wallet allows up to **20 members**, ensuring that the team can flexibly expand and increase operational personnel according to business needs, thereby improving management efficiency.

By dividing roles and setting permissions, the OpenBlock Enterprise Wallet achieves an efficient approval process. Members initiate transaction requests, and administrators approve and sign them, ensuring that each transaction undergoes strict review and control, thereby enhancing management efficiency and security.


## 2-2 TSS Key Management

Each member of the OpenBlock Enterprise Wallet adopts the 2-2 threshold model MPC key sharding scheme, enhancing the reliability of individual and team key management. The 2-2 model means that the user and OpenBlock each hold one shard, with no third-party involvement, and signatures must be agreed upon by the user, making it more decentralized.

**Equal Rights for Multiple Administrators**: The creator can invite multiple administrators to jointly manage the wallet. When inviting new administrators, the inviter, invitee, and OpenBlock will execute an MPC shard reset, generating a new set of 2-2 shards. This means each administrator holds a new set of 2-2 shards, ensuring equal rights and the ability to complete signatures with OpenBlock.
**Supporting Ordinary Members**: Administrators hold MPC shards and are responsible for approvals and signatures while inviting ordinary members who only hold public keys and cannot sign, similar to observer wallets. This makes the wallet usage scenarios more diverse.
**Approval Mechanism**: Multiple administrators can configure an m/n approval mechanism. The approval process is centralized, similar to traditional office approval flows. When the last administrator completes the approval, the signature will be completed on the chain.
**Mutual Backup and Recovery**: Each administrator must back up their local MPC shards. If a local shard is lost, any administrator can assist with recovery, similar to the process of inviting administrators.


## MPC Off-Chain Multi-Signature

Traditional multi-signature wallets require on-chain approval for each transaction, making many multi-signature scenarios complex and consuming multiple gas fees. OpenBlock adopts MPC off-chain multi-signature, where the approval process occurs off-chain through the team's MPC nodes before being submitted on-chain. This makes changing the signature model, modifying team members, and customizing approval workflows more flexible and efficient.

### Working Principle of MPC Off-Chain Multi-Signature
Generating Transactions: Users create a transaction to be signed in an online environment.
Off-Chain Approval: The approval process is conducted off-chain through the team's MPC nodes. All signers complete the signature process through the MPC protocol off-chain, effectively reducing the complexity and cost of on-chain operations.
Submitting Transactions: After off-chain approval is completed, the transaction is submitted to the blockchain network, and the transfer is finalized.

### Advantages of MPC Off-Chain Multi-Signature
High Approval Efficiency: Team members receive timely notifications and can complete approvals in the wallet backend, significantly improving approval efficiency.
High Security: Since the signing process is conducted off-chain, it effectively reduces the risk of network attacks, ensuring the security of digital assets.
MPC Security: Each multi-signature user uses MPC to prevent single-point key failures and malicious operations by individual signers, enhancing internal control reliability.


## Customizable Approval Workflow
Customizable approval workflow allows enterprises to set up the approval steps and permissions for digital asset transactions based on their business needs and management processes. This feature makes digital asset management more flexible and efficient. Teams can flexibly design custom multi-node and multi-approval models based on fund management permissions and actual processes.

**Defining Approval Rules**: Enterprise administrators can set transaction approval rules and processes through the OpenBlock Enterprise Wallet management backend. For example, transactions exceeding a certain amount require more signers' approval or specific types of transactions need departmental review.
**Assigning Approval Roles**: Based on internal responsibilities, different approval roles and permissions are assigned, ensuring each approval step has a clear responsible person.
**Dynamic Adjustment**: Enterprises can adjust approval workflows and rules as needed to ensure the flexibility and adaptability of management strategies.
Large Transaction Approval: For large digital asset transactions, enterprises can set strict multi-signature and approval workflows. For example, transactions exceeding a certain limit require signatures from multiple people and multiple approval steps, ensuring the safety and compliance of each large transaction.
**NFT Expenditure or Authorization**: Authorize operations for NFT expenditures.
Whitelisted Address Transaction Approval: Transactions to whitelisted addresses below a set amount can be approved through the current process.


## Sub-Wallet Management
The OpenBlock Enterprise Wallet allows each team to generate up to 30 sub-wallet addresses. Each sub-wallet address supports multiple chains, meaning enterprises can manage digital assets on different blockchains within the same sub-wallet. This multi-chain support greatly enhances the flexibility and convenience of asset management.

### HD Derivation Technology
OpenBlock adopts HD (Hierarchical Deterministic) derivation technology, making the generation and management of sub-wallets more efficient and secure. Through HD technology, enterprises can generate multiple sub-wallets from one master wallet, each with a unique derivation path, ensuring the independence and security of each sub-wallet address.


## Flexible API Library
The OpenBlock Enterprise Wallet API library allows users to automate the management of their enterprise wallets and on-chain asset transaction processes through programming interfaces. Enterprises can achieve various wallet operations through the API, such as creating wallets, querying balances, initiating and approving transactions. This automation significantly improves operational efficiency and reduces manual operation errors and delays.

### Backend Deployment and Integration
Enterprises can deploy API call interfaces in their backend systems to achieve seamless integration with their enterprise wallets. Through the API, enterprises can integrate wallet functions into existing business systems, such as ERP, financial management systems, or supply chain management systems. This integration allows enterprises to manage all digital assets on a unified platform, simplifying operational processes.

### Event Notifications and Responses
The OpenBlock Enterprise Wallet API library supports event notification functions. Enterprises can set up API interfaces so that when specific events occur within the wallet (such as large transactions or account changes), the system automatically sends notifications to the specified interface address. Enterprises can automatically trigger corresponding business logic based on these notifications, such as approval processes or risk control measures, to achieve real-time monitoring and management of digital assets.



### OpenBlock Enterprise Wallet Architecture

The OpenBlock enterprise wallet is designed using an innovative 2-2 TSS (Threshold Signature Scheme) architecture, specifically tailored for multi-admin corporate environments. With enterprise wallets often managing large sums of funds, absolute decentralization and security are paramount. Traditional multi-signature solutions rely on third parties or centralized services, which pose risks of single points of failure. OpenBlock’s 2-2 architecture effectively addresses these concerns.
![Image](vaultcopy.png)

#### 1.2-2 TSS Architecture: True Decentralization

In the 2-2 TSS model, both the user and OpenBlock hold one key shard each, with no third party involved. Any signature request must be authorized by the user, ensuring that no action can be taken without their consent. This eliminates the risks of third-party intervention, greatly enhancing decentralization and ensuring the absolute security of funds.

#### 2.Equal Rights Multi-Admin: Collaborative Management

OpenBlock supports a flexible multi-admin setup, where wallet creators can invite additional administrators to manage the wallet collectively. When new administrators are added, the inviter, the invitee, and OpenBlock collaboratively execute an MPC (Multi-Party Computation) key shard reset, generating a completely new and equally distributed 2-2 shard set. This mechanism not only enhances the flexibility of wallet management but also ensures that all administrators hold equal rights, reducing the risk of single points of failure.

#### 3.Support for Ordinary Members: Flexible Use Cases

The enterprise wallet allows administrators to invite ordinary members, who hold only a public key and cannot sign transactions. This functionality resembles observer wallets and is ideal for scenarios where multiple stakeholders are involved but only administrators need signing authority. Ordinary members can participate in day-to-day operations, while administrators handle key asset transfers, balancing security and convenience.

#### 4.Approval Mechanism: Configurable m/n Approvals

For more complex fund management workflows, OpenBlock provides an m/n approval mechanism, where administrators can configure custom approval rules. This centralized approval process functions similarly to traditional corporate workflows. Once the required number of administrators approve a transaction, the final signature is automatically generated and broadcast on-chain, ensuring both operational efficiency and on-chain security.

#### 5.Mutual Backup Recovery: Minimizing Key Loss Risk

Each administrator is required to back up their local MPC key shard. In case a shard is lost, recovery can be facilitated by any other administrator. The recovery process mirrors the key shard reset used when new administrators are invited, leveraging MPC to generate new 2-2 shards. This mutual backup mechanism not only preserves the security benefits of multi-signature setups but also significantly reduces the risk of key loss, providing robust disaster recovery for enterprise wallets.

By combining these features, the OpenBlock enterprise wallet offers a flexible, secure, and efficient management solution that fits a wide range of corporate use cases, ensuring both the safety and operational flexibility required for modern enterprise fund management.

 - **Excluded Assets**: Tokens with a fiat value less than 10 USDT will not be included in the asset snapshot. This reduces data load without significantly impacting overall revenue.
 - **Handling of Anomalous Tokens**: To avoid phishing or counterfeit tokens being counted in total asset value, processes are in place to handle such cases. However, it is not currently possible to completely prevent these tokens from being included, so periodic manual reviews are recommended.
 - **New Tokens**: Newly launched tokens may experience delays in asset inclusion and valuation.

- **Custodial Fee Rate**: Fees are based on the previous quarter's average daily asset holdings, with the following tiers:

| Average Daily Assets (USDT) | Fee Rate |
|-----------------------------|-----------------|
| {'<'}10,000 | Free |
| >=10,000 | 0.125% per quarter |

- **Billing Cycle**:
 - **Billing Period**: Daily asset snapshots taken during the current natural quarter.
 - **Settlement Period**: Fees are calculated as follows:

 **(Total Daily Snapshot Assets ÷ Actual Days) × 0.125% = Fee Due**
 
 - Fees must be paid within 30 days of the next natural quarter. If unpaid, certain wallet functions will be restricted until payment is completed.

- **Discount Codes**: Discount codes can be issued by the operations team for specific users, generated from the system's backend.

- **Numerical Rules**:
 - **Fiat Values**: Rounded to two decimal places.
 - **Percentage Values**: Rounded to two decimal places.
 - **Time Standard**: All times are based on GMT+8 at 23:59.

## 2.2 Late Payment Rules

If fees are not paid within the settlement period, OpenBlock will apply restrictions to the enterprise wallet and its sub-wallets. Specific rules include:

- **Late Payment Scenarios**:
 - **Single-quarter late payments**: Users must pay the outstanding amount for the previous quarter.
 - **Multiple-quarter late payments**: Users must pay the total outstanding fees for all overdue quarters. No additional late fees are considered at this time.

- **Late Payment Trigger**: If payment is not made within the settlement period, T+1 days after will be marked as overdue.

- **Late Payment Restrictions**: Once overdue, certain functions of the enterprise wallet and its sub-wallets will be restricted.

- **Status Restoration**: Once all outstanding fees are paid, the overdue status will be lifted and the wallet's full functionality restored.

# GasYourWay with OpenBlock

When exploring the world of Web 3.0, whether you're a novice user or an experienced player, you've probably encountered situations where there's insufficient gas for transferring or interacting with smart contracts. Gas fees are an unavoidable aspect of the journey into cryptocurrency investment and a crucial factor in the operation of blockchain platforms. To enhance user experience, OpenBlock has introduced two major features: **Gas YourWay** and **Gas Station**. These features aim to prevent users from running into situations where they don't have enough gas for transactions. Additionally, users can choose to pay gas fees with mainstream assets from any blockchain, offering more flexibility and making it easier for users to embark on their Web 3.0 journey!

## **What is the Gas Fee?**

"Gas fee" is a concept related to blockchain networks, particularly the Ethereum blockchain. On blockchain networks transactions, and smart contract executions require a certain amount of computational resources, and this resource is measured in units called "Gas." Gas fees represent the cost associated with performing operations on the blockchain network and are used to compensate miners for executing these operations and adding them to the blockchain. In simple terms, gas fees are fees that users pay to a blockchain platform to execute a transaction or interact with a smart contract.

## **What is Gas Station and Gas YourWay?**

### **What is Gas Station?**

The Gas Station feature of OpenBlock allows users to continue blockchain transactions even when they don't have enough gas by obtaining gas credits from other users, achieving gasless transactions. This feature significantly lowers the entry barriers into the world of blockchain, providing users with a smoother experience. Additionally, the Gas Station supports gas payments between users, allowing users to cover gas fees for other OpenBlock users, further enhancing the spirit of community support. This feature not only simplifies the blockchain transaction process but also promotes broader adoption, significantly reducing the barriers to entry for Web 3.0.

### **What is Gas YourWay?**

In most blockchain networks, transaction fees are typically paid using the native gas token, which often requires users first to acquire the native gas token before they can initiate transactions. This process can be confusing and inconvenient for new users. With OpenBlock's Gas YourWay feature, users can easily pay gas fees using other authorized tokens, without the need to worry about acquiring and managing the native gas token. This feature allows users without native gas tokens to smoothly engage in on-chain transactions, without being restricted to using only the native gas token for payments. The Gas YourWay feature provides a simpler and more convenient experience for Web 3.0 users, giving them more options while exploring Web 3.0.

### **What is the difference between the two features?**

Both OpenBlock's Gas Station and Gas YourWay features aim to enhance the Web 3.0 user experience, but they have different focuses and roles. Gas Station focuses on providing gas credits to users, enabling them to grant gas limits to their own wallet addresses or other user accounts without the need for transfers, allowing them to continue blockchain transactions even when they don't have enough native gas tokens. This reduces the barriers to entry into the Web 3.0 world and enhances user liquidity.

The Gas YourWay feature, on the other hand, addresses the issue of acquiring and managing native gas tokens by allowing users to pay gas fees using authorized tokens. This means users don't have to worry about obtaining native gas tokens and can easily transact, making it particularly suitable for novice users.

## **How to use Gas Station and Gas YourWay?**

### **How to use Gas Station?**

OpenBlock Gas Station now supports Ethereum, BSC, and Polygon chains. Users can authorize or use ETH, BNB, and Matic credits from other OpenBlock users for gas payments. OpenBlock Gas Station now supports transfers and OB Swap, with plans to support more use cases in the future.

1.To access OpenBlock Gas Station, log in to your [OpenBlock](https://openblock.com/#/) account, click on the Gas icon in the upper right corner, and select Gas Station. You can also use Gas Station to view the current Ethereum gas price estimates, making it easy to choose the optimal timing for your transactions right from within the wallet interface.

![](static/GI6db0Zo9ostP7xwkP8uT6FesGf.png)

2.Click on "Top-up," and choose the token you want to deposit as gas fees. (Currently, gas payments are only supported for transfers on Ethereum, Binance Smart Chain (BSC), and Polygon. More chains and usecases will be added in the future.）

![](static/FbRIb4LmxokMoTxgfpxuxpjnsJf.png)

# How does the transaction fee or gas fee work?

v1.2

---

On any blockchain, a transaction or gas fee refers to the cost necessary to perform a transaction on the network. Miners, for example, Ethereum miners, set the gas price based on supply and demand for the network's computational power needed to process smart contracts and other transactions. Gas prices are denoted in small fractions of the network coin called gwei. For example, if you use the Ethereum network, the gas fee will be a small fraction of ETH.

Bitcoin and Ethereum networks are the two most expensive chains. You can consider using other similar chains to trade coins for much lower gas fees. In addition, the gas fee is dynamic. In general, the heavier the blockchain traffic is, the higher the gas fee. It is because the miner will prioritize the transaction that paid the higher gas fee to process; therefore, you can manually adjust the gas fee to a higher level if you wish to accelerate the transaction. See the instruction below to learn more about how to customize the gas fee.

Finally, you can check the network gas tracker to decide whether to do a transaction now or later.

## Steps to customize gas fee:

1. Log in to your OpenBlock account and click **The** **Wallet **on the top right of the page.
2. On the left bar menu, select the chain network (e.g., ETH) you wish to send your tokens.
3. Click the **Setting **icon (looks like a gear that is above the Send button).
4. Enable the **Advanced Gas Control **and return to the wallet.
5. Click **Send, **and then enter the receiver's **blockchain address** and **sending amount**.
6. Click **Transaction Fee**, and then you can adjust the gas fee accordingly.

# How to Setup Google Authenticator?

v2.0

---

Google Authenticator (GA) is a free security app that can protect your accounts against password theft. It provides the most robust security for your OpenBlock account by requiring two-factor authentication (2FA) when initiating transactions. 2FA makes it much more difficult for bad actors to impersonate your identity. Even if bad actors steal your password, the 2FA will lock them out of the account.

Google Authenticator generates a random code on a 30-second basis. Entering a valid random code will confirm your identity, enabling an extra layer of protection. It works without Internet and Network coverage.

Though Google Authenticator is optional, enabling it for increased security is strongly recommended. Our risk management model indicates a strong security boost for wallet assets of more than 10k USD.

## **How to enable Google Authenticator**

1. Download Google Authenticator (GA) app from your mobile device's APP store(iOS/Android).

![](static/boxusAw27KIYg0fpYZWsPhHGOXe.png)

2. Open the downloaded GA app and click **Get started**.
3. Log in to the OpenBlock account.
4. Click **Account Security **on the top right of the page, then **Google Authenticat****or****,** then **turn on** Google Authenticator.
5. On your mobile device, click **Scan a QR code **in the GA app (or click **Enter a setup key** if your camera cannot scan).
6. (Android only) Click **Reveal the key**, and a 6-digit code will be displayed.
7. (Android only) Click **Add account** to finish the Google Authenticator setup.
8. Back to the OpenBlock page, click **Next, **and enter the Email verification code as well as the Google Authenticator code.
9. The success setup message will show up if the code entered is correct.

Note: If you lost your 2FA by accident, contact support@openblock.commailto:support@openblock.com to reset the Google Authenticator.

## **How to disable Google Authenticator**

1. Go onto the **Google Authenticator **setup page, and **turn off** Google Authenticator. Paste the email verification code and Google Authenticator.

## **If you receive a "2FA code error" after you input your Google Authentication code**

- Synchronize the time on your mobile phone (to synchronize your Google Authenticator app) and your computer (from which you attempt to log in).
- Clear your browser cache and cookies.
- Try to log in from our dedicated mobile app.

# How to backup MPC Units?


---

## Why do you need to back up the MPC Unit

To validate a new device for your wallet, you must undergo a device validation process (MPC TSS). This can be done by importing a backed-up MPC Unit or through a device sync. You need to export the MPC Unit from a validated device. Only one instance of the local MPC Unit can be backed up at a time, as each export automatically expires the previous one. For security, keep the local MPC Unit at all time. The wallet displays validated devices in the device management tab, where you should regularly monitor and manage access. Additionally, stay vigilant by checking email alerts and implementing recommended safety measures for your OpenBlock wallet.

## When is the MPC Unit import available?

If you have a backed-up local MPC Unit, you can import it to any new device at any time.

# How to better protect your OpenBlock account?

v1.5

---

OpenBlock embraces MPC technology as the center of its security scheme. We strongly suggest users learn about how MPC wallet works to understand the potential risks at stake better. The user can also follow the standard practices listed below to minimize the chances of losing your crypto asset or wallet.

## Behavior recommendations.

Be cautious of phishing Email and SMS messages trying to impersonate OpenBlock. OpenBlock will ONLY send you emails from the domain @OpenBlock.com. Triple-check the website URL before entering the wallet or inputting credentials. Malicious actors usually impersonate URLs by shuffling letters.

OpenBlock will never ask for your credentials outside of the wallet through Email, phone calls, or Text.  Never share or confirm your account with anyone.

Never sign a wallet transaction that leads to [https://OpenBlock.com](https://OpenBlock.com) prompt from an Email.

## Device Management

Do not log in to your wallet on a public computer. If you do, clear the browser cache to delete the copy of the MPC Unit imported in the first place. Deleting your browsing history will minimize exposure to the random public.

OpenBlock designs to have the Web Browser portal remember your login status for 30 days for better accessibility. This feature may not be ideal for laptops and in situations where devices can be lost or stolen. Be aware of the device environment, and try signing out your wallet each time finishing using it.

Due to the implementation of MPC schemes, the user can log in to their wallet from multiple devices and platforms. OpenBlock will provide the best tool for the user to manage the logged-in devices. Still, the user is responsible for minimizing the number of these devices, in which fewer access points would be less vulnerable to potential attacks.

Please utilize our Enterprise Wallet as a team or a project. This powerful feature exponentially increases your wallet's safety.

## Credential Management

Email is the primary verification method in OpenBlock. Please always keep your Email safe. OpenBlock recommends using a less commonly used or a dedicated Email to sign up.

Password and Payment PIN are the next defense system in the OpenBlock wallet. They are structurally different, one with complicated digit letter sign combinations and the other with six digits. Please keep them fundamentally different when coming up with these passwords. Furthermore, separate them from your regular Email password and mobile device PIN.

OpenBlock provides multiple 2 Factors Authentication (2FA) methods to protect the account. Please enable them as soon as possible after signing up. 2FA would shield your account with a third layer of verification if someone were to crack through the first two.

Secure Email is the last but not least security method to verify the user's identity. It is required when resetting the MPC Unit. Please keep this Email at minimum risk for the user's benefit, preparing for the worst case of losing all the devices and every MPC Unit. Without it, the user cannot recover from the MPC Unit loss.

The last piece of advice is always to remember not to publically disclose and describe the details of your devices, your credentials, and your assets. Feel free to contact us with any concerns or questions.


# How to export your Private Key

V 2.0

---

## Export the private key from OpenBlock wallet

Although MPC units have advantages over private keys, such as security, easy management, and social recovery. For users who still need to export their private keys, we also provide an "offline recovery tool" to recover mpc units to private keys safely. The specific recovery steps are as follows:

1. First of all, the wallet you plan to export private keys to needs to be a social recovery wallet, or a wallet address that has been converted to social recovery mode.
2. Then find the "Social Recovery MPC Unit" button in My Wallet, Manage Wallet page, follow the guide to ask the social host to provide the social recovery MPC unit and upload it to the specified location, then click Export Private Key to complete the private key export.

## Using the private key exported by OpenBlock wallet

The private key is proof of account ownership. Please keep the exported private key in a safe place. It can be imported into a traditional EOA wallet for use, or a hardware wallet for storage.

## Introduction: EdDSA private keys can not be imported and exported temporarily.

In public-key cryptography, the Edwards Curve Digital Signature Algorithm (EdDSA) is a digital signature scheme that uses a variant of the Schnorr signature based on a twisted Edwards curve, which was proposed by Daniel J. Bernstein et al. in 2011.The EdDSA signature algorithm generates a digital signature by computing a set of random numbers and a private key, which signature can be verified by the verifier using the corresponding public key.

EdDSA: Edwards-Curve Signature Algorithm as defined in RFC 8032

Ed25519: Edwards-Curve Signature Algorithm for Ed25519 as defined in RFC 8032

Ed448: Edwards-Curve Signature Algorithm for Ed448 as defined in RFC 8032

The EdDSA algorithm signature is commonly used for private key generation for ordinary hot wallets, and its generation steps are as follows:

1. Select an Edwards curve, such as the commonly used Ed25519 curve.
2. A 32-byte random number is randomly selected as the seed, which can also be obtained from a secure random number generator.
3. Convert the seed into a 32-byte byte array with the hash function and use it as the private key
4. Calculate the public key by the transformation formula of Edward curve

The EdDSA private key generation in MPC usually uses a distributed key generation algorithm, which can divide a private key into multiple parts, each part being held by different participants, so as to achieve the secure generation and management of private keys.

Since hash-type algorithms are less friendly to MPC multiparty computation, the process of creating EdDSA private keys in the MPC wallet system is directly calculated using the values after ScalarBase, and since the results of the hash algorithm are irreversible, it can be roughly understood that no seed private keys can exist in the MPC algorithm. Therefore, there may be compatibility problems when an EdDSA private key derived from the MPC wallet system is loaded into a normal hot wallet. Most hot wallets will hash this private key as a random seed. Instead, as mentioned above for the MPC wallet private key generation, the MPC wallet maintains and can export a value that has been ScalarBase and hashed. Compatibility issues may arise due to differences in private key formats and calculation methods. Compatibility issues can be solved by using the ScalarBase calculated value as the private key instead of the step of converting the seed into a 32-byte byte array as the private key via the hash function.

We hope that more traditional EOA wallets will participate in the future and develop a standard solution to solve this compatibility problem.

## Where is the private key for MPC wallet?

The private key in a common hot wallet is a set of randomly generated characters, and the length of the private key is typically designed to be 256 bits in order to prevent from being cracked. The wallet user who holds the private key will have absolute ownership of the crypto wallet. The private key is usually not visible, and usually encryption algorithms reduce the private key to 12-24 simple English words for easy storage. A major disadvantage of mnemonics, however, is the risk of "single point of failure". Tokens are very vulnerable to loss, theft, and forgetfulness. Not only can all users with a wallet token access the wallet and all of its funds, but there is no remedy for the loss of a token.

The OpenBlock wallet uses MPC (Multi Party Computation) technology to replace the private key with an MPC unit. This technology generates private keys in a distributed manner, generating different private key fractions directly on the user side and on the server side, maximizing the multi-party security of the wallet. The private key of the wallet is split from the beginning, and the complete private key never appears from the beginning to the end, which solves the possibility of private key loss and theft and greatly reduces the risk of users managing the wallet by themselves.

## Export Private Key through the "Offline Recovery Tool:

Caution: Please be advised that once the Private Key is being exported, your MPC wallet will no longer be recoverable. You take full responsibility of your assets and account. Please consult OpenBlock support before proceeding.

Although MPC units have advantages over private keys, such as security, easy management, and social recovery. For users who still need to export their private keys, we also provide an "Offline Recovery Tool" to recover mpc units to private keys safely. The specific recovery steps are as follows:

First of all, the wallet you plan to export private keys to needs to be a social recovery wallet, or a wallet address that has been converted to social recovery mode.

Then find the "Social Recovery MPC Unit" button in My Wallet, Manage Wallet page, follow the guide to ask the social host to provide the social recovery MPC unit and upload it to the specified location, then click Export Private Key to complete the private key export.

1. Click the **MPC unit icon** in the upper right corner

![](static/S7ezbPaquoYmylxW3syux43rsVh.png)

2. Contact the Social Custodian and obtain the **MPC Unit of this wallet**, upload it and export the private key. (To isolate potential network risks, this step needs to be done with the **network disconnected**)

![](static/DtvqbZB5uodOwExSc8iuwRFEs0g.png)

3. After the successful export, the EcDSA private key will be split into two segments for displaying. Combine the two segments to extract the complete private key.

# How to reset the MPC Unit


---

## Why do you need to reset the MPC Unit?

The validation of the local MPC Unit on your device is the essence of your wallet security. Only the validated devices can access the wallet and initial transactions. OpenBlock provides users with two methods to validate a new device: [device sync](https://openblock-support.zendesk.com/hc/en-us/articles/6878253680027) and [MPC Unit import](https://openblock-support.zendesk.com/hc/en-us/articles/6955258133659). The user should learn how to manage the validated devices and keep the account safe at all times.

However, if the user loses all his validated devices and the backed-up local MPC Unit by accident, these two methods are no longer viable. This is similar to losing the seed phrase or the private key in a traditional crypto wallet. Fortunately, the OpenBlock MPC mechanism is designed to eliminate such a single point of failure.

[T](https://openblock-support.zendesk.com/hc/en-us/articles/6991541876763)[he MPC protocol and the 2-3 TSS architecture](https://openblock-support.zendesk.com/hc/en-us/articles/6991541876763) allow the user to reset the entire MPC Unit rotation. The lost local MPC Unit will be replaced by a new local MPC Unit by the end of the reset, recovering access to the wallet. The reset is also available for the user who believes the local MPC Unit is compromised. Throughout the reset, the user's asset, public address, and account ownership will remain untouched.

Since the reset is the last resort for account recovery, the entire reset procedure is well-designed against phishing, scams, and hackers. OpenBlock implements a 2-day pending period during the reset. This addresses the situation where a hacker logs in to the account with phished credentials and initiates a reset to compromise assets further. During this 2-day pending period, OpenBlock will push email notifications, as reminders, daily to notify the user of an ongoing reset action. If unrecognized, the user may immediately cancel the reset.

OpenBlock has applied a few more rules for extra layers of security:

1. Transactions are disabled during the 2-day pending period.
2. The reset can be initiated anytime on any device, however, it can only be completed on the device that initiated it.
3. After the reset, all previously validated devices and the backed-up MPC Unit will expire.

# How to sync to a new device?

v2.3

## What is a device sync?

A device validation is required when you sign into your wallet on a new device. In the validation process, your local MPC Unit is parsed with the server MPC Unit, unlocking the wallet after successful verification. There are two ways to validate: device sync and import a backed-up MPC Unit.

The device sync is a quality-of-life feature to increase accessibility while maintaining security. This feature allows you to synchronize and copy your local MPC Unit from a validated device to a new, unvalidated one. This new device is then validated after the sync. The feature is supported across different devices on all platforms.

![](static/boxusKg9ELTPv80KYGSTFoGpVxC.png)

The wallet will display each validated device on your device management tab. Always check your email for wallet alerts, your device management tab for logged-in devices, and log-out devices that no longer need access.

## Steps to sync to a new device（Webside）:

1. Log into your wallet from a new device.
2. Confirm if this new device is unvalidated and has validated devices available to sync from.
3. On the new device, **choose the available device to validate.**

![](static/boxusmUrQjBswED2XxsAX6aAzIe.jpg)

# How to use pay Gas with other tokens?

v2.0

---

# What is GasYourWay?

Currently, major public blockchains only support native tokens for paying gas fees. This requires users without native gas tokens to acquire them before use by transferring them into their wallets.

OpenBlock's GasYourWay feature allows you to use pre-authorized tokens in your wallet to cover the gas fees, fulfilling your needs for transactions without native gas tokens and easing your journey of blockchain exploration!

Example, use USDT as Gas on BNB.

### Supported Blockchains:

GasYourWay by OpenBlock is now available on Ethereum, BSC, and Polygon chains. You can use any mainstream pre-authorized assets, such as USDT, USDC, and DAI, to pay for gas fees.

## Use GasYourWay in OB Trade

1. Click “Trade” in the top menu to enter the OBTrade Swap feature page.
2. Select the trading pair you need for the swap or cross-chain transaction. Click on Gas, Other tokens, and choose the authorized token you want to use for gas fee payment. The first time you use a new token to cover gas fees, you will need to authorize it. The initial token authorization will be free, paid by the OpenBlock platform.

# OpenBlock DID Domain Name

v1.0

---

## What are Web3 Domain Names?

Web3 domain names are held in your wallet in a decentralized form and can be used to interact with other DApps and smart contracts. There are many benefits to having a web3 domain names. As opposed to a traditional crypto wallet address of 42 characters, which is difficult to remember, the immediate benefit of a web3 domain namesis that user can have a shorter, easier to remember address that is less likely to make a mistake when making or receiving payments.

For example, you can easily send encrypted transfers to each other's domain names "alice.eth" than confirming a 42 character transfer address 0x55add7893w8edd9qq9023fqdz934xx1fc0azde7c multiple times before each transfer. At the same time, the web3 domain name is also an NFT that is exclusive to you, it is unique and interchangeable. Your web3 domain names will be your digital identity for social interaction in the web3 world.

Web3 domain names are very different from the web2 traditional Domain Name System (DNS). On web2 , domain name owners have limited control over their domain names due to centralization. But in the web3 space, thanks to blockchain technology, web3 domain name owners have ultimate control over their domain names.

Based on the unstoppable boom of web3, people are eager to try out the various advantages and conveniences of web3 domain name. Now OpenBlock Wallet introduces the ability to support SpaceID, ENS, .bit, Twitterscan and AptosPassport domain names, and with this new feature. Users can use the short domain feature on ETH, BSC, Polygon, Tron and other chains. You will have an even better experience with web3.

# OpenBlock KYC

V 1.0

---

# What is OpenBlock KYC?

OpenBlock KYC is a new decentralized digital identity and trust credential for Web3, aggregating the authentication results of major KYC providers. It uses technologies like zero-knowledge proofs (ZK) to achieve off-chain authentication and on-chain self-verification, protecting user privacy while verifying and proving personal information. During the KYC process, authentication takes place on the KYC provider's page, so OpenBlock does not store any plaintext KYC information, only obtaining the results of KYC verification to ensure comprehensive data security.

# How to complete OpenBlock KYC?

1. Address signature generates ZK ID. Use an address on the BenFen Mainnet to sign on-chain and generate a ZK ID. Each address has a unique ZK ID used for identifying KYC results on the blockchain.
2. Document upload and biometric identification. Upload identification documents such as passports, ID cards, or Hong Kong and Macau pass permits, and complete facial recognition. Successful authentication follows official database checks by the KYC provider.

# What are the features and core advantages of OpenBlock KYC?

1. KYC platform aggregator. It aggregates the authentication results of major KYC providers on-chain. KYC completed on any platform can be found on the blockchain, allowing for one address to query multiple KYC results with one click.
2. On-chain usability. It uses W3C's DID and VC protocols to store KYC result data off-chain, and a unique self-verifying data on-chain technology replaces oracles, allowing easy data sharing with on-chain smart contracts while ensuring data authenticity. Users truly own their identity data and can flexibly use their KYC verification results to drive business with smart contracts at the protocol layer.
3. Supports peer-to-peer identity verification. Third-party smart contracts can access user information as a simple KYC check (passed/failed) or more complex identity information based on zero-knowledge proofs. OpenBlock KYC, while fully protecting user privacy, passes various elements of user identity proof, including location, age range, income level, credit rating, and risk preference, to smart contracts in a peer-to-peer manner.

# How does OpenBlock KYC work?

OpenBlock KYC cooperates with Legit ID, which provides KYC information verification and encryption. KYC information, after being encrypted with ZK, is stored at Legit ID, and the KYC authentication results are deployed in BenFen Mainnet's smart contracts through self-verifying data on-chain technology. When KYC privacy information needs verification, the verifier and the verified use their private keys to encrypt and decrypt the KYC information in a peer-to-peer manner, thus completing the authorization and verification of information.

# How is the security of KYC data ensured?

Both OpenBlock and Legit ID do not store any user's original KYC information, only storing encrypted KYC information. Users need to use their private keys for signature decryption to access all KYC information. Therefore, without the user's authorized signature, no one can access the original KYC information.


# OpenBlock MPC Wallet User Manual

v2.3

---

An OpenBlock account gives you access to OpenBlock's powerful non-custodial MPC wallet, a secure and easy-to-use browser extension OpenBlock Bridge, and a widely accepted OAuth account to log into tons of other Web3 applications. You only need one minute and one Email address to start surfing Web3 with OpenBlock!

## What is an MPC Wallet?

Multi-party Computation (MPC) is a concept of cryptographic security. This protocol requires the consent of multiple parties before execution, and only one party's consent alone would not be enough to obtain control of the wallet. The MPC wallet is a cryptocurrency and digital asset wallet that uses multi-party computation to offer strong security and effectively avoids single-point failure.

## Why use an MPC Wallet?

MPC wallet provides users with superior security. Currently, it is still very challenging for hackers with MPC technology. In order to gain control of a user's wallet, a hacker would have to attack the computing sides that store the MPC units simultaneously across multiple platforms and locations, which is far more difficult than attacking a single verification point.

## Why OpenBlock?

The initialization of OpenBlock Wallet will generate an independent MPC unit on the user's local device, OpenBlock server, and third-party cold storage. Any two of the three MPC units are signed after running the Multi-party Computing (MPC) protocol. This 2-3 threshold signature management solution does not generate any full private keys, minimizing the risk of a single-point failure. Suppose a user loses all access to the wallet. In that case, OpenBlock Social Recovery will activate the recovery MPC unit of the exclusive wallet and help the user regain control of the wallet. The registration process for OpenBlock Wallet is simple and easy, supports Google Account and Apple ID third-party login, and supports SpaceID, ENS, .bit, Twitterscan, AptosPassport, and other mainstream short domain name binding functions.  Meanwhile, it also supports gamefi items, collectibles, event tokens, and other NFT assets, making it easy for users to participate in airdrops, trade events, and display collectibles.

## **Step 1: Create an OpenBlock Account**

1. Click **Login/Register** from the OpenBlock home page.
2. Enter your Email address as your account ID.

![](static/boxuskBCuW1XxHRqUtvjIwz6zEd.png)

3. Click **Continue.**
4. Enter a six-digit verification code retrieved from your Email. Check the spam folder if needed.

![](static/boxuslcTBjsNhEa6Co64RnbJLDV.png)

5. Set a strong login password that is 8 to 20 characters long, and contains at least an uppercase letter, a lower case letter, a digit, and a special character (!, +, #, $, %).
6. Click **Next.**
7. Set a six-digit Payment PIN that will be used to verify your identity in initiating transactions.

![](static/boxusqpzVWo5jddoEAeeLjowiSh.png)

8. Now you are able to see the OpenBlock’s dashboard. Start exploring OpenBlock!

![](static/boxusUAsooq81SaoDKUWHrEwzUc.png)

## **Step 2: Protect your account with recovery info and security methods.**

It is important to secure your account with 2FAs and recovery information. OpenBlock provides a lot of security features for users to suit their needs for security. It is recommended to set up Google Authenticator.

# OpenBlock Swap V2.0 creates a CEX trading experience!

Based on the four versions of cross-chain Swap iteration V1.0, OpenBlock Sawp V2.0 is now officially on line, and the LP concept of cross-chain application in the ascendant opens a perfect storm. This 2.0 version can be said to be OpenBlock's trading experience close to centralised exchanges for the purpose of adjusting the layout and reducing the cost of users. Swap V2.0 will provide a more friendly, convenient and multi-methods trading process, as well as faster trading speed, lower commission, more asset choices and richer product features.

The goal of this update: to build a CEX trading platform with a decentralised approach and provide wallet users with an unprecedented trading experience.

### **CEX Trading Experience Realisation**

**One-click Swap:**

OpenBlock Swap V2.0 technology has already implemented multi-chain flash exchange. In the one-click flash exchange in the "Transactions" section of the homepage navigation bar, it now supports cross-chain fast exchange transactions for 10 chains and multiple coins. When you manually fill in the corresponding exchange amount, the system will automatically identify the optimal path for buying and selling, and provide the optimal cross-chain and flash exchange solution for users who conduct on-chain transactions. With the speed and convenience of one-key flash exchange, users can easily realise free cross-chain transactions and reduce gas loss without switching between multiple chain accounts under the pattern of one super-multiple master chains.

**Asset Percentage Progress Bar:**

Effective market information contains the judgement of price. And to achieve the highest flexibility of the market on the chain, it needs the framework of excellent general liquidity as the market operation and maintenance means. In the update of Swap V2.0, the innovation is the Quote token and Base token single-coin market maker model where buyers & sellers are not related to each other. Users can manually interactively set the percentage amount of the transaction, and in the PMM pricing mechanism, the quantity of the two tokens in the pool is unrelated to each other, allowing single-coin market making to exist. In addition, the algorithm uses adjustable parameters, the more Base Tokens that are bought, the higher the price, and the parameters can be modified to reduce the slippage, thus amplifying the liquidity and increasing the use of funds.

Swap V2.0 defaults the Base token to ETH and the Quote token to USDC, and the transaction direction is divided into two major parts: buy and sell, both of which are based on the Base token. if the user stays in the current chain, the default recommended token area will give priority to the Native token, **which eliminates the cumbersome on-chain pricing logic, and achieves the U Native CEX trading experience.**

![](static/CaopbtZw8oXOwHxmuVGuwdS0sFg.png)

Swap V2.0 not only enables buyers and sellers to freely choose stablecoins from different chains. At the same time, there is a pull-and-click interaction design for the progress bar of the exchange amount, which intuitively displays the visual effect in the progress bar preferred by the user, and produces a pre-priced result regardless of whether the user has sufficient amount. When the user has no relevant amount and selects the progress bar, the data in the input box remains unchanged; when the user has relevant amount and selects the progress bar, the data in the input box changes accordingly.

**Selection of Token and Price Impact:**

Considering to provide users with a convenient and fast experience as much as possible, based on the chain's filtering and default configuration, OpenBlock chooses to keep the current mechanism unchanged. As a result, a new popular token area has been added, as well as a view of history, with complete display of every transaction information details, making it easy for users to track all chain operation behaviours, safely and efficiently. Popular search recommendations have 10 major stablecoins of different chains, in addition, this V2.0 version added support for real-time price and up and down views. Provides a variety of popular stablecoins to choose from, exchange USDT price real-time update, intuitive up and down data, investors can according to personal preference for financial investment.

(1) Price impact is only calculated for new orders;

(2) The amount of new orders is displayed according to the gradient of the stall, showing the calculation of the corresponding price impact;

(3) The default value of the gradient is: $100$500$1,000$5,000$10,000$50,000$100,000$200,000$500,000$1,000,000;

![](static/WSycboXMEoevkRxGhJvurTjms1f.png)

In addition to this, there are two types of charts available for users to visually analyse future price movements. The charts are divided into Basic (line charts) which contain price displays from 24 hours to 1 year, and Pro (candlestick charts) which contain price displays from 1 day to 5 years.

![](static/RqjcbPlkXoa9UFxaDyCu3qxisKc.png)

### **Swap V2.0 New Optimisations**

**Fast withdrawal:**

In the cross-chain aggregator function, Swap V2.0 uses cBridge as the cross-chain service provider for cross-chain, in extreme cases, there may be abnormal situations of card assets, in order to cope with this kind of scenario, V2.0 has added a quick withdrawal function to help you quickly retrieve your assets, which really achieves the safety and efficiency that other wallets can't achieve in the CEX transaction, and it is cleverly designed from the user's point of view so that Everyone can experience the chain transfer of every transaction with peace of mind.

![](static/AVkQbsw1FoYHdExkpFQuTaOLsZr.jpeg)

**Other Optimisation Details:**

**Search optimisation:** more user-friendly smooth experience making sense.

**Currency list optimisation:** add contract address. In the transaction process, add the view and copy function of the contract address, which is convenient for users to determine the token of the transaction and avoid unnecessary transfer of the wrong address. At the same time, the copying and jumping of hovering appearances are added to the web terminal, and the viewing portal is added to the client terminal.

**Optimisation of route loading:** When users enter the exchange amount and wait for the route to choose the best path, silent loading is triggered and no loading is displayed. In addition, Swap V2.0 is also a time-friendly player, the route loading speed is now optimised to less than 3s, which means the route loading time is shortened to 20s.

### **Trading Pair Configuration**

Popular configurations:

Ethereum (USDT, USDC, DAI)

BNB Chain (USDT, BUSD, USDC)

Polygon (USDT, USDC)

Optimism (USDT, USDC)

Arbitrum (USDT, USDC)

Avalanche (USDT)

# What are the Private Keys, Public Keys, Seed Phrase, and Public Addresses?

v1.5

---

## The Private Key and the Public Key

A Private Key to a cryptocurrency wallet is like a physical key to a mailbox. It is a randomly generated number, usually 256 bits long, designed to be impossible to crack. A typical Private Key looks like this "e600106a60733a1ae3cb3e3c59e362b47d2c90d76388dg47fd493h1b2efbd28c".

Wallet users holding the Private Key prove their absolute ownership of this crypto "mailbox"; therefore, they should never share this Private Key with anyone.

From the Private Key derives a set of Public Key, like the mailing address of a physical mailbox. The algorithm ensures a Public Key is impossible to reverse to generate a Private Key. Thus one can safely share the Public Key for others to deposit crypto. When someone deposits crypto to this Public Key, one can accept and retrieve this fund by presenting the correct Private Key.

## The Seed Phrase and the Public Address

The Private Key and Public Key are usually not displayed; instead, algorithms allow simplified formats to be shared and memorized.

The 256-bit Private Key is divided into 16 sets of 16-bits, each 16-bits representing an English word, a Seed Phrase. A typical Seed Phrase looks like this: "autumn saddle loyal dinner pink settle bulb sad forget absurd fever fog cat table grey tree." This 16-word Seed Phrase is the new form of the Private Key, thus, should be memorized or stored in a safe place that no one else should know.

The 256-bit Public Key is hashed into a shorter set of numbers called Public Address. A Public Address for Ethereum looks like this: "0x17504553eBA2433e6952e75f4b80D23c0d519AE1". This is the new form of the Public Key one should share with other people.

## Disadvantages of the Seed Phrase and OpenBlock's solution

One major setback of the Seed Phrase is its tendency to a single point of failure. The Seed Phrase is easily subjected to being lost, stolen, and forgotten. Not only is anyone processing this Seed Phrase able to access the asset, but there is also no remedy for recovering it if lost.

In combat for a better solution of the current Private Key and Seed Phrase model, OpenBlock wallet presents the MPC solution in which Private Key is now replaced by several MPC Units distributed to different parties. It is more secure as multiple MPC Unit conditions must be met for wallet access and transaction initiation. It also enables the capability to reset the MPC Unit and recover the account.

Regardless of which form, Seed Phrase or MPC Unit, is adopted to represent the Private Key, the user is held responsible for keeping them imperatively safe. Feel free to talk to our support representative about any questions you have.


# What is HD Derivation?

v1.0

---

For an enhanced user experience, OpenBlock continuously researches and upgrades the experience and security of its MPC wallet. The OpenBlock wallet now supports HD derivation, combining its convenience with the security of MPC technology.

This allows users to enjoy the ease of management and recovery provided by the HD structure while benefiting from the high security standards of MPC technology.

*Only newly created sub-wallets can utilize the HD derivation feature.

# What is HD Derivation

HD Derivation (Hierarchical Deterministic Derivation) is a cryptocurrency wallet technology that allows generating a series of key pairs (public and private keys) from a single seed (usually a sequence of words or numbers). The core of this technology is the BIP32 (Bitcoin Improvement Proposal 32) standard, which defines how to use a master seed to create a hierarchical and orderly structure, thereby deriving multiple child keys.

Each child key can be used as an independent wallet, allowing users to remember only the initial seed to recover access to all related accounts and funds.

1. Master Private and Public Keys: The master private key is the root of the key tree, from which all other keys (private and public) are derived.
2. Derivation Paths: By defining different derivation paths, different child private and public keys can be generated from the master private key. These paths follow certain rules (such as the path represented by m/44'/0'/0'/0), where each layer can represent different meanings (such as currency type, account, address, etc.).
3. Extended Keys: Each private key can generate a corresponding public key, and due to the characteristics of the encryption algorithm, the parent public key can derive child public keys without knowing the child private keys. This means that the parent public key can be made public to generate receiving addresses without exposing the corresponding private keys.

## The main benefits of HD derivation include:

1. Enhanced Privacy: By generating a new address for each transaction, address reuse is avoided, thereby increasing user privacy.
2. Easy Backup and Recovery: Only the initial seed needs to be backed up to recover access to all derived keys and addresses, simplifying the backup process.
3. Organizational Structure: Allows creating complex sub-account structures as needed (for example, different sub-accounts for different purposes), facilitating management.

# How HD Derivation is Implemented in an MPC Wallet

The MPC wallet uses multi-party computation technology to distribute the storage of private keys, thereby enhancing security. Implementing HD derivation in an MPC wallet involves how, without directly exposing private keys, to cooperatively compute new key pairs along the HD derivation path through the collaboration of multiple participants.

## OpenBlock has now integrated HD derivation technology:

1. Sub-Wallet Key Derivation: When users create a sub-wallet, the master seed of the main wallet will be used to cooperatively compute the child key pairs along the HD derivation path through MPC, completing the initialization of the sub-wallet. The key derivation steps are also carried out through the MPC protocol, ensuring that keys are generated and used without exposing any segments of the private key.
2. Using and Managing Keys: OpenBlock users need only backup a single MPC unit to import all addresses on the entire key tree, greatly simplifying the backup and recovery process.


# What is MPC and MPC Unit

v2.2

## **W****hat **are** MPC and MPC Units?**

Secure Multiparty Computation (MPC / SMPC) is the cryptographic principle of computing multiple parties' data without revealing it to each other. Through an MPC algorithm, multiple stakeholders own a piece of the secret, and the secret only reveals upon putting all pieces together.

**MPC wallet is a type of wallet that applies multiparty secure computing technology to the process of creating blockchain wallets, and the main difference between MPC wallet and other wallets is the difference in its Distributed Key Generation method.**

The private key is generated in a Distributed Key Generation (DKG), which directly generates different private key slices on the user side and the server side, and the multi-party security is reflected here. This article focuses on introducing MPC wallet technology. In order for you to clearly understand this technology and its future development prospects, we start with **Distributed Key Generation** and **Threshold Signature Scheme**.

### 1. **DKG, Distributed Key Generation**

Distributed Key Generation aims to solve one problem: getting rid of the reliance on trusted authorities.

Many cryptographic logics require an initialized private key in the encryption process, and this private key is usually generated and managed by a trusted third-party authority, which poses security problems such as single point of failure and private key escrow. Distributed Key Generation is free from dependence on trusted third parties by computing a shared set of public and private keys with the participation of multiple parties.

### 2. **TSS, Threshold Signature Scheme**

Threshold Signature Scheme is an MPC key management scheme for Distributed Key Generation and signing cryptography.

Threshold Signature Scheme is characterized by the fact that a signature must be generated by a private key, but this private key will not be held by anyone in its entirety,it will be divided into many pieces instead, which can be held by multiple people at the same time, and then through the MPC protocol. Users would be able to generate a legitimate signature directly without the need to put all the pieces together.

In cryptocurrency, the MPC principle is applied to the Private Key, allowing each party to hold a share of the Private Key, called the MPC Unit. A signature can be signed only until all the MPC Units are verified and parsed together.

OpenBlock adopted a 2-3 TSS architecture. By design, three parties are entitled to a single wallet, each behold an MPC Unit hashed file. Any two MPC Units can interact or parse through the MPC algorithm to complete a signature.

## **The OpenBlock Solution**

OpenBlock algorithmically generates one MPC Unit, on-premise for each party: the user, the server, and the cold storage**. **The three MPC Units are fundamentally different, and, by OpenBlock's technological design, any two can interchangeably parse with each other. When the user logs into OpenBlock on a device storing a validated MPC Unit, the server prompts the user to validate his identity for the server's MPC Unit. With both MPC Units now present, the MPC algorithm parses them to unlock the wallet and sign a signature.

If either MPC Unit is invalid, meaning the user does not have a validated device or does not complete the identity validation, the wallet will remain locked. This is a secure design to fence off attackers or scammers who may have compromised the account information partially. But if the user no longer has his MPC Unit, whether lost, forgotten, stolen, or compromised, the wallet will also remain locked for the user.

To resolve the situation, the third MPC Unit stored in the cold vault comes to use. This MPC Unit will fulfill the 2-3 TSS requirement to access the wallet. Then, the user can trigger a recovery mode that, through another MPC algorithm, reset all three MPC Units to a different set of hashed files, regaining access to the wallet.

## The user's MPC Unit

Through account initialization, the MPC algorithm generates the user's MPC Unit directly on the user's device. For a browser, the MPC Unit will store in the browser's hidden path; for a mobile device, the MPC Unit will keep in the App system file. This device, as the first device, is then automatically validated.

The user can access the wallet with any device containing the validated MPC Unit anywhere and anytime. This would require the user to transfer the MPC Unit from the first validated device to any other device with multiple secure methods. This underlines the security principle OpenBlock adopts, which is, that only the user is able to physically validate devices; the attacker simply cannot remotely access the wallet and retrieve funds.

## The server's MPC Unit

This MPC Unit stored on the server will only be released into parsing when the user validates the identity.

passes security checks (password, Payment PIN, Verification Code, etc.).

The server increases its validation level to release this second fragment on an action-based scale. Logging in requires the correct Email, password, and Email Verification. A transaction requires a password and Payment PIN. Resetting MPC Unit requires Login Email's Verification Code, Payment PIN, and Secure Email's Verification Code. With 2FA enabled, any actions changing security settings will require a 2FA passed. The different combination allows OpenBlock to create a matrix of security measures for risk management, exponentially increasing the difficulty of being hacked.

When the user signs in to their account on a new device or browser that does not have the first fragment stored, he will not be able to access the wallet. Passing all the security checks only grants the second fragment from the server. The user will have to present the user's first fragment by either Local Sync or Import the MPC Unit Fragment from his local file folder.

The user can lose all of the copies of his MPC Unit fragment if he loses all his logged-in devices and deletes or reinstalls all his web browsers without a backup. Now the user can only recover access by resetting the MPC Unit. The reset process disqualifies the combination of the previous three fragments and resets the MPC Unit into a new set of three fragments. Follow the instruction of the resetting process to initiate. Please remember that resetting the MPC Unit takes seven days to complete to avoid unrecognized reset by hackers or accidental scams. Therefore, OpenBlock recommends that the user not rely on this function and learn how to manage the MPC Unit Fragment safely.

# What is Social Recovery?

v1.3

---

## What is wallet recovery?

In traditional EOA wallets like MetaMask, the wallet is unrecoverable if the private key is lost. In OpenBlock, powered by its MPC protocol, a dedicated Recovery MPC Unit will begin to function when the user loses all given access to his wallet (all of his validated devices and all backups). The user can use this Recovery MPC Unit to initiate an MPC Unit reset that essentially resets all three MPC Units and recovers the wallet access. OpenBlock offers two recovery methods, OpenBlock Safe Recovery and Social Recovery. OpenBlock Safe Recovery is the default method, which utilizes a cold vault managed by the OpenBlock Safe team to store the Recovery MPC Unit. When the user's wallet access is absent or compromised, he can retrieve the Recovery MPC Unit with the OpenBlock Safe Recovery to reset the entire MPC Unit rotation, regaining wallet access.

## What is Social Recovery?

**Social Recovery** is another wallet recovery method that leverages a trusted OpenBlock wallet, a guardian, to store the Recovery MPC Unit. The guardian can be your friend or yourself. This guardian is accountable for your Recovery MPC Unit's safekeeping and responsible for transferring it to you when you need it for wallet recovery. This method gives the user flexibility in storing the Recovery MPC Unit. However, the guardian is held accountable for the user's wallet recovery. **If the guardian loses the user's Recover MPC Unit, the wallet will not be recovered, and assets will **be **unrecoverable. In this case, please reapply for a new Social Recovery as soon as possible to ensure that Social Recovery is available.**

Social Recovery can be active during wallet registration or upgraded at any time during subsequent use. Since the initialization process requires the approval of the guardian, both the initiator and the guardian must be online simultaneously. Please inform your guardian in advance.

1. The guardian will be notified in both the email and the wallet, prompting a Social Recovery setup procedure.
2. The guardian should log in from his validated device and follow the steps.
3. After the procedure finishes, the user's Recovery MPC Unit will be initialized and stored directly onto the guardian's device. The guardian should choose to back up this file for additional security.
4. The guardian will be prompted for this Recovery MPC Unit when the user initiates a wallet recovery.

## 

## How to set up a Social Recovery

### 1. When creating an OpenBlock wallet, click **Switch to Social Recovery** under "Continue".

![](static/boxusOeNorPMxnQt6gImUu3m3Jq.png)

3. Verify

Enter the **6-digit Email Verification Code, Payment PIN, **and inform the trusted third party of the **6-digit Trust Code**. At the same time, the trusted third party will need to log into their OpenBlock wallet and enter this** 6-digit Trust Code**.

![](static/boxusvLk3mzpVGB5txiLgSm4xFf.png)

### 4. The social recovery settings are complete.

Your MPC Recovery Unit has been saved in **MPC Unit Management** → **Social Recovery** → **My Safe** on the local device of the trusted third party. The trusted third party should back up the MPC Recovery Unit for additional security.

# What is dust UTXO error?

v1.0

---

## What is Dust?

Dust refers to a tiny amount of tokens in fractional values that is even less than the transaction fee required to send them, hence unspendable. Dust exists in all UTXO-based token families: BTC, BCH,  LTC, DOGE, RVN, and DGB. It is a bi-product that may pollute the ecosystem and overloads it with inefficient work done in data storage and time (though the amount is tiny, it requires the same data storage as other valid transactions).

## What is a dust UTXO error?

The balance of the UTXO-based token is a display of a sum number, which consists of the actual spendable amount plus multiple instances of dust. Again, because dust is less than the value of the amount of transaction fee to send it, each dust remains isolated and unused but still accounted for calculating the sum balance. The UTXO error occurs as the sum of these multiple instances of dust is invalid.

For example, a bitcoin address may contain 0.0087 BTC. In reality, it consists of three UTXOs of 0.0080, 0.0002, and 0.0005. Since the transaction fee for each UTXO is 0.00055, the 0.0002 and 0.0005 are then dust. Sending 0.0087 will trigger the dust UTXO error, and spending 0.0080 is acceptable.

The network will reject this transaction before processing it, which will slow down the network and require more transaction fees than it's worth.

## How to resolve dust UTXO error?

1. The best practice is not to send small amounts of transactions less than the transaction fee. The network will auto-reject the attempt.
2. Adjust the transaction fee to a lower bracket just so that the dust amount is slightly higher to process. But remember that a lower transaction fee may extend the transaction processing time to days.
3. Send the very last remaining of your balance with the "Max" amount button, as it, by design, excludes the dust.

# What is the MPC Unit status?

v1.0

---

## What is a validated status?

OpenBlock recognizes a user when he, first, can log in on a device and, second, has his local MPC Unit presented on this device. When an account is logged in on a new device, it is, by default, unvalidated. At this very instance, OpenBlock can assume it's a hacker with a phished credential operating behind this new device. The local MPC Unit must be present to have this device validated. There are two methods to present this local MPC Unit; both require confidential information only the true owner can access. The first method is to sync the local MPC Unit from a validated device remotely. The second is to import a backed-up local MPC Unit. Either method will prove the device's identity to OpenBlock and will validate the device.

If the user loses all of his validated devices and the backed-up local MPC Unit by accident, OpenBlock cannot make an exception to recognize him or this new device blindly; this may be another trick a hacker trying to compromise the account. To counter this, OpenBlock implemented a reset procedure designed for the true owner to perform under the above situation. After the reset, the user can recover his access to the account and start fresh with the MPC Unit and the device validation. Learn more about how the MPC Unit reset works here.

## What are the different device validation statuses?

### Unvalidated：

1. A new device that has not been validated with any MPC Unit, or any device that is logged in for the first time.
2. A device that has been validated with an MPC Unit before, but the MPC Unit is now expired.

### Validated:

1. A device that has been validated with an MPC Unit.

## When will each validation method be available?

1. When validated devices exist, the user can view, choose and sync from any of the devices from the list.

![](static/boxusr28PTrVRmfeljjiGgIHhgp.png)

2. If you do not see any validated devices to choose from, you may only validate new devices by importing a backed-up MPC Unit file if available.

![](static/boxusAspSpgePYw3uEAikH1UqrH.png)

3. If you do not see either validated devices or an available backup, you will not be able to validate the device from either method. You have to reset the MPC Unit to regain account access.

# What to do if the token balance is incorrect?

v1.1

---

First, check the wallet address on a block explorer website corresponding to your network (i.e., Etherscan for Ethereum mainnet, Arbiscan for Arbitrum, etc.) If the block explorer displays a consistent incorrect balance, proceed with the steps below.

## If your balance is incorrect after a recent transfer:

### **Unstable internet**

1. Change to a different network. OpenBlock cannot communicate with the server to load the correct balance if the internet is weak or unstable.
2. Refresh the wallet page and re-open your browser.
3. Check if you are in an unfamiliar network environment or on a VPN that may have internet ports blocked.

## If you are still experiencing incorrect balance, check out the listed reasons below:

- **Wrong wallet account and address**: Please check your recent transactions and verify if you have sent your crypto asset to the correct wallet address.
- **Wrong network chain**: Please check if the chain you send the crypto-assets is the same as you currently selected in the OpenBlock wallet. For example, if you send ERC20 USDT, you need to change your wallet to the Ethereum chain to see the USDT balance; other chains, such as BNB, HECO, ARB, etc., will not show the USDT balance if you select ERC20 to send it.
- **Pending transaction status**: You may experience a delay if the network traffic is high and a low gas fee is paid. Other reasons for pending status may include risk control, unusual network traffic,  or a transaction that is just stuck.
- **Unusual high gas fee**: In an extreme situation, the gas fee may cost a fortune. If you signed a transaction and did not acknowledge such a high gas fee, you may experience an "unknown" loss due to unawareness of paying the gas.

## If your balance is incorrect WITHOUT any recent transfers:

- **Log**** ****in to a wrong wallet account**: if you have multiple accounts, please check if you sign in to the correct wallet account.
- **Pre-authorized ****T****oken ****A****pproval**: DApps, NFT platforms, Airdrop claims, Defi platforms, or other Web 3.0 websites may ask for your signature on a Token Approval for a certain amount of authorized transactions. They are then entitled to transfer your approved amount within the agreed time limit. Check your token approval under OpenBlock wallet's token page for the approval history.
- **Check for unrecognized transactions**: Check on transaction records to see if someone other than you has initiated a transfer on your tokens. A hacker may have compromised your account and transferred funds without your knowledge.

If you have already checked all the above situations and still believe the token balance is incorrect, contact our support team immediately at [support@openblock.com](mailto:support@openblock.com).  Please provide us with as much information as possible (e.g., screenshots of the transaction confirmation page, corresponding TxID, etc.), and we will investigate your case accordingly.


# Why is the transaction in pending status?

v1.0

---

When you submit a transaction on Ethereum or a compatible network, your gas price is a bid to the network to process your transaction sooner. If you submit with a low gas price, you can find your transaction taking a long time to process. For advice on what gas prices will result in a transaction being finalized in a reasonable amount of time, please refer to sources such as Etherscan's gas tracker  or a similar tracker for whichever network you're using.

Additionally, there are sometimes circumstances where something goes wrong, and a transaction is just stuck, or pending for a very long time.


## OpenBlock 企业钱包
在当前的数字经济时代，随着区块链技术的不断发展和应用，企业对数字资产管理的需求日益增长。OpenBlock 企业钱包应运而生，致力于为企业提供安全、高效、便捷的数字资产管理解决方案。本文将详细讲解 OpenBlock 企业钱包的功能、优势以及其在企业数字资产管理中的应用。

本文将详细描述 OpenBlock 企业钱包的特点：团队职能、2-2 TSS 私钥管理、MPC 链下多签、自定义审批流、子钱包管理及灵活 API 库。

## 团队职能
### 管理员
管理员是OpenBlock企业钱包中的核心角色，负责整个钱包的管理和配置。OpenBlock企业钱包允许最多6个管理员，确保管理职能的分散化和冗余性，防止单点故障和权限滥用。管理员角色的权限和职责包括：

**邀请和管理成员**：管理员可以邀请新的成员加入钱包团队，并管理现有成员的权限和角色。
**配置钱包设置**：包括设置多签规则、自定义审批流和安全策略等。管理员可以根据企业的需求，灵活调整钱包的各种配置。
**审批和签署交易**：管理员有权审批和签署交易，确保每一笔交易都符合企业的安全和合规要求。
**监控和审计**：管理员可以实时监控钱包内的所有活动。

### 成员
成员是OpenBlock企业钱包中的操作角色，负责日常的数字资产管理和操作。OpenBlock企业钱包允许最多20个成员，确保团队可以灵活扩展，根据业务需求增加操作人员，提高管理效率。成员角色的权限和职责包括：

**发起交易**：成员可以发起交易请求，但需要管理员的审批和签署后才能生效。这确保了交易的安全性和合规性。
**查看交易记录**：成员可以查看钱包的交易记录，了解账户余额和资金流动情况，便于日常管理和操作。
**参与多签审批**：在多签规则下，部分成员可能被分配签署权限，参与到多签流程中，确保交易的安全性和分权管理。


通过角色分工和权限设置，OpenBlock企业钱包实现了高效的审批流程。成员发起交易请求，管理员审批签署，确保每笔交易都经过严格的审核和控制，提高了管理效率和安全性。


## 2-2 TSS 私钥管理
OpenBlock 企业钱包中的每一位成员都将采用 2-2 阈值模型的 MPC 私钥分片方案，提升个人及团队私钥管理的可靠性。2-2 意味着用户和 OpenBlock 各持有一个碎片，没有第三者的存在，签名必须经过用户同意，更加的去中心化。

**多管理员平权**：创建者可以邀请多个管理员协同管理钱包，当邀请新的管理员时，邀请者、被邀请者、OpenBlock 三方会执行 MPC 碎片重置，产生一组全新且等效的 2-2 碎片。这意味着每个管理员都持有一组全新的 2-2 碎片，人人平权，都可以配合 OpenBlock 完成签名。
**支持普通成员**：管理员持有 MPC 碎片，负责审批和签名，同时可以邀请普通成员进入。普通成员仅持有公钥，无法签名，类似观察者钱包。这使得钱包使用场景更加丰富，比如：可以邀请普通成员进入帮忙代玩游戏，而涉及游戏资产转移时，必须有管理员确认签名，安全且便捷。
**支持审批机制**：多个管理员可以配置 m/n 的审批机制，审批是中心化流程，类似传统的办公审批流。当最后一个管理员完成审批时，会同时完成签名上链。
**支持互备恢复**：每个管理员必须备份好自己本地的 MPC 碎片，当本地碎片丢失，可以找任何一个管理员协助恢复，原理和邀请管理员时一样，具体参考「私钥重置」章节。因此，多管理员相当于互相备份，实现多签效果的同时，大大降低私钥丢失的风险。


## MPC 链下多签
传统的多签钱包每一笔审批都在链上，使的很多多签场景复杂且耗费多笔 gas 费。OpenBlock 采用 MPC 链下多签，在一笔待签署的交易创建后，该审批会在链下经过团队的 MPC 节点审批通过后，才会传到链上。这使得团队成员在更改签名模型、修改团队成员与自定义审批流都将更将灵活高效。

### MPC 链下多签的工作原理
**生成交易**：用户在在线环境下创建一笔待签署的交易。
**链下审批**：交易创建后，审批过程通过团队的MPC节点在链下进行。各个签名人通过MPC协议共同完成签名，这些操作在链下完成，有效减少了链上操作的复杂性和成本。
**提交交易**：链下审批完成后，交易被提交到区块链网络，最终完成转账。

### MPC链下多签的优势
**审批效率高**：团队成员将会收到及时通知并在钱包后台即可完成审批，极大提升了审批效率。
**安全性高**：由于签名过程在链下环境中进行，有效降低了网络攻击的风险，确保了数字资产的安全。
**MPC安全**：每个多签用户自身都采用MPC，防止私钥单点失效和单个签名人恶意操作，增加了内部控制的可靠性。



## 自定义审批流
自定义审批流（Customizable Approval Workflow）是指企业可以根据自身的业务需求和管理流程，设定数字资产交易的审批步骤和权限。这一功能使得企业在进行数字资产管理时更加灵活和高效。团队可根据资金管理权限及实际流程进行弹性的设计自定义的多节点、多审批模型的审批流。

**定义审批规则**：企业管理员可以通过 OpenBlock 企业钱包的管理后台，设定交易审批的规则和流程。例如，设定交易金额超过一定数额需要更多的签名人批准，或特定类型的交易需要特定部门的审核。
**分配审批角色**：根据企业内部的职责分工，分配不同的审批角色和权限，确保每个审批步骤都有明确的责任人。
**动态调整**：企业可以根据实际需求，随时调整审批流程和规则，确保管理策略的灵活性和适应性。
**大额交易审批**：对于金额较大的数字资产交易，企业可以设定严格的多签和审批流。例如，交易金额超过一定限额时，需要多人全部签署并通过多个审批步骤，确保每笔大额交易的安全和合规。
**NFT支出或授权**：针对 NFT 支出进行授权操作。
白名单地址交易审批：当交易地址属于白名单且交易金额低于设置的数值时，通过当前流程进行审批。


## 子钱包管理
OpenBlock企业钱包允许每个团队生成最多30个子钱包地址。每个子钱包地址都可以多链支持，意味着企业可以在同一个子钱包中管理不同区块链上的数字资产。这种多链支持极大提升了资产管理的灵活性和便利性。

### HD 派生技术
OpenBlock采用HD（Hierarchical Deterministic）派生技术，这种技术使得子钱包的生成和管理更加高效和安全。通过HD技术，企业可以从一个主钱包生成多个子钱包，每个子钱包都有其唯一的派生路径，确保了每个子钱包地址的独立性和安全性。


**灵活 API 库**
OpenBlock企业钱包的API库允许用户通过编程接口自动化管理其企业钱包及链上资产的交易流程。企业可以通过API实现对钱包的各项操作，如创建钱包、查询余额、发起和审批交易等。这种自动化管理极大提升了操作效率，减少了手动操作的错误和延迟。

**后端部署与集成**
企业可以在自己的后端系统中部署API调用接口，以实现对企业钱包的无缝集成。通过API，企业可以将钱包功能集成到现有的业务系统中，如 ERP、财务管理系统或供应链管理系统。这种集成使得企业能够在统一的平台上管理所有数字资产，简化了操作流程。

**事件通知与响应**
OpenBlock 企业钱包的API库支持事件通知功能。企业可以设置API接口，当钱包内发生特定事件时（如大额交易、账户变动等），系统会自动发送通知到指定的接口地址。企业可以根据这些通知自动触发相应的业务逻辑，如审批流程、风险控制措施等，从而实现对数字资产的实时监控和管理。





### OpenBlock 企业钱包架构解析

OpenBlock 采用创新的 2-2 TSS（门限签名方案）架构，专为多人协同管理的企业钱包设计，确保资金托管的高度安全性和去中心化特性。企业钱包通常涉及较大的资金流动，传统的多签方案往往依赖于第三方或中央化服务，无法完全消除单点失效和安全隐患。OpenBlock 的 2-2 架构有效解决了这一问题。
![alt text](vault.png)

#### 1.2-2 TSS 架构：真正的去中心化管理

2-2 TSS 意味着用户和 OpenBlock 各自持有一个私钥碎片，且不存在第三方持有或参与。任何签名请求必须经过用户的授权，才能最终生成完整的签名。这种设计避免了第三方介入的风险，大幅提高了钱包的去中心化程度，确保资产的绝对安全。

#### 2.多管理员平权机制：多人协同管理

OpenBlock 支持多个管理员的平等管理机制，钱包创建者可以邀请其他管理员加入，进行协同管理。每次新管理员加入时，由邀请者、被邀请者和 OpenBlock 共同执行 MPC（多方计算）私钥碎片重置，生成一组全新的 2-2 碎片，确保每位管理员都持有全新的、平等的私钥碎片。这种机制不仅提升了管理的灵活性，还保证了所有管理员在决策和签名过程中的平等地位，极大地降低了单点失效的风险。

#### 3.支持普通成员：灵活使用场景

OpenBlock 企业钱包允许管理员邀请普通成员进入钱包体系。普通成员仅持有公钥，无法参与签名操作，类似于观察者钱包。这种设计特别适用于复杂的使用场景，比如需要多方协作但无需所有成员参与签名的场景。普通成员可以参与日常操作，而涉及关键资金转移时则由管理员进行签名确认，兼顾了便利性和安全性。

#### 4.审批机制：m/n 灵活配置

企业钱包通常涉及复杂的资金管理流程，因此 OpenBlock 提供了 m/n 的审批机制，管理员可以灵活配置审批规则，确保资金转移符合公司的内部合规流程。类似于传统办公的审批流，当所有必要的管理员批准后，最终的签名会自动生成并上链，确保高效的操作流程与链上安全的完美结合。

#### 5.互备恢复机制：降低私钥丢失风险

每位管理员都需备份自己持有的 MPC 碎片，以防本地设备损坏或丢失时，可以通过其他管理员进行恢复。恢复过程类似于新管理员加入时的私钥重置流程，通过多方计算生成新的 2-2 碎片。这种互备机制不仅确保了钱包的多签安全性，还大大降低了因意外导致私钥丢失的风险，为企业钱包提供了更高的容灾能力。

通过以上架构和功能的结合，OpenBlock 企业钱包为用户提供了灵活、安全且高效的管理体验，适用于多种复杂的企业场景，进一步提升了资金管理的安全性与可操作性。

# OpenBlock 企业钱包收费标准指南

OpenBlock 企业钱包仅记录 TON 代币资产，其他资产如 NFT 和 LP 代币不计入评估范围。托管费的收取将基于上一季度的平均每日资产，具体规则如下：

- **资产评估标准**：
 - 仅记录钱包内的已认证 TON 代币资产。
 - **不计入资产**：折合法币小于 10 USDT 的代币不会被计入资产快照。这一规则能减轻每日快照数据量，且对整体收益影响较小。
 - **异常代币处理**：为避免钓鱼代币和假币被计算在总资产中，系统会设置相应的处理流程。但现阶段无法100%杜绝异常代币，需要定期手动复核。
 - **新代币**：对于新上线的代币，资产统计可能会在短时间内滞后。

- **托管费费率**：托管费根据上季度平均单日资产收取，具体费率如下：

| 平均单日资产（USDT） | 收费标准 |
|--------------------|----------------|
| {'<'}10,000 | 免费 |
| >=10,000 | 每季度 0.125% |

- **周期**：
 - **计费期**：每个自然季度的每日资产快照。
 - **结算期**：费用将在下一自然季度的30天内结算。公式为：
 
 **每日快照资产总和 ÷ 实际天数 × 0.125% = 应缴费用**

 - 若未在30天内完成支付，部分功能将受限，允许在欠费期内补缴。

- **折扣码**：运营团队可为特定用户发放折扣码，折扣码的生成由系统后台处理。

- **数值规则**：
 - **法币数值**：保留两位小数。
 - **百分比数值**：保留两位小数。
 - **时间**：所有时间为 GMT+8 23:59。

## 2.2 逾期限制规则

在逾期情况下，OpenBlock 将对企业钱包及其子钱包的部分功能进行限制，具体规则如下：

- **逾期场景**：
 - **单季度逾期**：用户需补缴上一季度的欠费。
 - **多季度逾期**：用户需补缴多个季度的欠费，目前暂不考虑收取额外的逾期费用。

- **逾期触发**：如在结算期内未完成缴费，则在 T+1 日后标记为逾期。

- **逾期限制**：逾期后将限制企业钱包及其子钱包的部分功能。

- **状态恢复**：补缴所有欠费后，逾期状态将被解除，钱包功能恢复正常。

## 2.3 支付方式

OpenBlock 企业钱包支持多链支付，主要接收稳定币，具体支付方式如下：

| ETH | USDC, USDT |
| Matic | USDC, USDT |
| BSC | USDC, USDT |

- **支付逻辑**：
 - 仅支持通过前端界面支付，确保用户选择正确的链、代币和金额，减少处理成本。
 - 账单支付可通过企业钱包内任意子钱包进行，支付地址将自动从当前钱包提取。
 
- **收款地址**：每条链将设有专用的托管费收款地址，用户应向指定地址进行转账。

- **支付校验**：系统通过前端界面和交易哈希双重校验，确保支付成功。

- **目标收款地址**：由运营和财务团队共同管理，确保收款安全。

# Base | Farcaster 融资 1.5 亿美元，追更 $Degen 大主角的币圈爽文！

## DEGEN 投资价值

Farcaster 是基于 OP Stack 的社交协议，用户拥有 ETH 钱包即可注册。2021 年，Farcaster 拿到了 A16Z 领投的 3000 万美金的天使轮融资。2024 年 5 月 22 日，Farcaster 宣布完成 1.5 亿美元融资。由 Paradigm 领投，a16z crypto， Haun， USV， Variant， Standard Crypto 等参投。

目前， Farcaster 已支持 Arbitrum 交易，并且与 Arbitrum 共同推出「Frame It.」开发者激励活动，并提供 50 万美元的追溯奖励；Farcaster 生态正在稳步发展，日活超过 4 万，许多社交引用开始以 Farcaster 协议为基础，构建琳琅满目的 SocialFi 产品，例如 Warpcast 等。

2024 年 1 月，Degen 频道在 Farcaster 上线，允许用户使用 $Degen 奖励优质内容创作者，这种激励方式引发了社区的极大热情，将Degen频道，甚至整个Farcaster的活跃度推向高潮，而$Degen 的价格也随着热度不断上涨。

2024 年 2 月，Degen 宣布完成了 490.5 ETH 的天使轮融资，由 1confirmation 领投，Farcaster OG 和其他机构参与。这些资金将用于发展 Degen 生态系统和社区，并对一些社区项目进行了捐助，例如 Drakula 项目。

随着项目的不断发展，$Degen代币的应用场景也在不断拓展。除了Drakula项目，NFT平台 Zora，社区项目 Bracket.Game 和 Rounds.wtf 都开始使用 $Degen 作为实用代币。

Degen 起源于 Farcaster 社区，又在爆火之后反哺着 Farcaster 社区，为 Farcaster 带来了一波快速的用户增长。

$Degen 从一个 Meme 币，逐渐发展为实用代币，又发展为 L3 公链的原生代币，甚至有可能升级为 Farcaster 乃至整个 Base 链的平台币。

## Degen，当之无愧的 base meme 之王

$ Degen是Base链社交协议Farcaster中最重要的频道的代币，于2024年1月推出，主要用于内容打赏和用户激励。随后，Syndicate发链团队基于Arbitrum Orbit和AnyTrust技术，将$Degen 作为原生代币, 重新构建了一套基于 Base 的 Layer 3 系统，即 Degen Chain。

根据 Dune 统计，截止到 5 月 20 日 8:00（UTC），$ DEGEN 代币在 Base 链上的持币地址约为 43.5 万个，累积交易量超过 15 亿美元，而其 L3 链 DEGEN ChainBridge 的累积用户超过 3 万人，累计桥接金额超过 862 万美元。

![](static/PhJibxHpOocxhKxcPTouNdlNscc.png)

![](static/XrjObbnQ8oLMfex4YFAu6airsIS.png)

从数据来看，$ Degen 是目前 Base 链上当之无愧的 Meme 之王。

用于内容打赏的 meme 币故事，最早起源于$Doge。而$Degen 和$Doge有着很多的相似点，且发展速度和趋势比$Doge 更猛。

由于 farcaster 本身并不发币，就有了所谓“Base 生态看 Farcaster，Farcaster 热度看$Degen”的共识, $Degen 代币在 Warpcast 中势不可挡，应用场景和使用人数迅速发展，很有可能破圈而出，承担起整个 Farcaster 协议的平台币的功能。

除了 farcaster 之外，$Degen 也成为了多个新型 socialfi 的打赏代币，具有成为”社交金铲子“的极大潜力。

这才是以 $Degen 为主角的币圈爽文，且仍在连载，值得追更。

### **其他用例如下：**

Drakula：一款类似 TikTok 的 onchain 短视频应用，用户可以使用 DEGEN 进行内容打赏和交互

Clubcast：类似 Patreon 的 onchain 平台，允许内容创作者通过 token-gated channels 提供专属内容。

## 如何购买 degen

## Socialfi 新范本 farcaster 是什么 有哪些价值

**Farcaster 是一个去中心化社交媒体协议，为开发者、创作者和普通用户提供一个开放且可组合的社交层。**

### **1. 链上部分**

Farcaster 的链上元素主要包括智能合约，这些合约运行在以太坊的 Layer 2 上（Optimism），这些合约处理一些核心功能，包括：

- ID 注册：为新用户生成与其以太坊地址关联的密钥对，确保身份的唯一性和安全性。
- 存储注册：管理用户数据存储空间的分配和年费收取，保证数据的可靠存储。
- 密钥注册：管理用户的公钥和私钥，允许用户授权和撤销对账户的控制权，从而进行安全的消息签名和身份验证。

![](static/BcN6bhogroW120xmJawuVNQ9svf.png)

### **2. 链下部分**

Farcaster 的链下元素包括一组称为 Hubs 的服务器，这些服务器在传统的硬件上运行，负责处理不需要链上确认的数据操作，以加快响应速度并减少交易成本。具体功能包括：

- 消息处理：Hubs 负责接收、验证和存储来自用户的 Casts（用户发布的内容）。它们检查每条消息的签名是否有效，以及是否符合用户在链上注册的身份信息。
- 数据同步和传播：一旦消息被验证，Hubs 将消息存储在本地，并与网络中的其他 Hubs 同步，确保数据的一致性和可靠性。
- 性能优化：通过在链下处理大量数据交互，Hubs 可以显著减少链上交易的需求，从而降低延迟和成本。这对于社交网络平台尤为重要，因为它需要处理大量的即时交互。

### **3. Frames**

本质上是一种在 Farcaster 帖子中嵌入的小型应用程序，它们使得帖子不仅仅是静态内容的展示，而是可以成为交互式的平台。用户可以直接在社交媒体交互中访问各种功能和服务，无需离开 Farcaster 平台。 例如：

- NFT 交互：用户可以通过 Frames 铸造、展示或交易非同质化代币（NFT）。例如，一个艺术家可以在帖子中直接展示其艺术作品的 NFT，并提供购买或出价的选项。
- 游戏：开发者可以将简单的游戏直接嵌入到帖子中，用户可以在浏览社交媒体的同时玩游戏。
- 内容订阅：允许用户订阅 newsletter 或其他媒体内容。内容创作者可以通过 Frames 提供专门的订阅按钮。

## Wrapcast/Firely 你了解多少

### Wrapcast

Warpcast 是建立在 Farcaster 社交底层协议的一个客户端，支持 iOS 及安卓。Warpcast 属于 Farcaster 社交底层协议的官方直属平台项目。

采用社交账户的方式，每个账号由邮箱地址和绑定的 EOA 钱包组成。创建账号即绑定钱包并支付 $5 一次性费用（注册费 + 上链费）。注册成功后提醒用户备份助记词。

![](static/PjVdbjp0poTweexHCNeurXZysjf.jpeg)

Wrapcast 的社交形态相当于 Reddit 论坛和推特个人主页的融合。在用户的首页，点击顶部圆圈可以进入关注的/社区任意发帖和品论，下滑也可以浏览个人新动态并评论。

![](static/R1c0bqSLzogIr6xWClDuCBcjsGe.jpeg)

Farcaster 社交底层协议及 $DEGEN 代币的兼容赋予了 Wrapcast 多种链上内容及玩法，同时参与 $DEGEN 的空投积分活动。Farcaster 定义下，发帖（叫做 Cast）可以收到任何用户的 $DEGEN 打赏。所以 Wrapcast 上的用户和 Cast 发帖也可以打赏或被打赏。

每个贴可以点击“Action”打开菜单功能。可以显示发帖人的 $DEGEN 打赏额度。可以添加打赏金额，使与其交互的用户获取 $DEGEN 奖励。多种基于 $DEGEN 代币的玩法大幅提高了 Wrapcast 社交活跃性的上限。

![](static/Yp9Eb8iOxoDaCKx1Lw5um664sMS.jpeg)

### FireFly

![](static/U4hvbu1m8oiA63xhC38up9DEsBa.png)

firefly.social

FireFly 是一个聚合了 Farcaster（WrapCast 登录），Lens 和 Twitter 的社交平台聚合，支持网页端，iOS 段，MAC 电脑端和安卓端的登录。可以用任意平台的账号进行登录，并将各个账号与钱包绑定在一起。

![](static/AU1QbWmNgoUOjRxDloRuHI0osoI.png)

FireFly 的社交形态集成了推特个人主页、Reddit 论坛、链上任务平台与抽奖、及 NFT LaunchPad。与 Wrapcast 完全兼容 Farcaster 的初衷不同，FireFly 暂时没有兼容 $DEGEN 系列玩法，而是更关注在多个社交平台联动的设定上。

![](static/GTbhbneJYoe2qAxXiSbu0OTIsnd.png)

Firefly 将 LuckyDrop 等链上抽奖（奖励代币或 NFT）整合进了发帖功能内，可实现一键发帖、发任务、发奖励。

![](static/UDkebT8kZoQNdxxOULQu34mrsUe.png)

$Build 代币于 5 月 14 日上线，目前持币地址超过 15K，交易数超过 63K，价格稳步提升，表现抢眼。

![](static/Bi4QbSJALo1SvOx1ZLPufmHFseh.png)

Base 链创始人之一的 Jesse 也多次提到 Build 项目，认为其有潜力成为“Universal Builder Income”

![](static/JpekbHhK0oAV6UxQQELuTZ31sLb.png)

根据 Build 的代币经济学，将有 50% 的代币用于空投，第一轮空投将在 6 月结束。可以通过以下链接参与项目建设，赢取空投奖励。

# BenFen：探索 SFT 的世界：BenFen 第一个原生支持 SFT 挖矿公链

![](static/ETx1bOwPHotddIxY2toupaULsUf.png)

# 引言

SFT（半同质化代币）结合了 ERC-20 和 ERC-721 的特点，是一种新兴的代币模式。自从 ERC-1155 到最新的 ERC-404，SFT 引起了业界越来越多的关注，并为 FT 和 NFT 市场带来了新的解决思路。随着应用场景的不断扩展，SFT 已从最初的游戏领域延伸至 DeFi 领域。在币圈，“新颖即吸引”一直是一种流行的观念，只有不断创新的技术才能实现广泛应用。此外，公链挖矿模式也经历了从 PoW 到 PoS、PoA 的演进，各方不断寻求更优化的解决方案。目前，尽管公链还未普遍支持 SFT 挖矿，但 BenFen 作为首个结合 PoS 挖矿机制与 SFT 的平台，开辟了一种全新的思路和玩法。本文将深入探讨 SFT 作为一种结合了 FT 和 NFT 的新协议的定义、优势及其市场潜力，并详细介绍 BenFen 这一首个原生支持 SFT 挖矿的平台的特点和潜力。

# 什么是 SFT

SFT （半同质化代币)， 首次由 Enjin 的区块链团队于 2018 年开发，利用 ERC-1155 标准创建了独特的、可交换的游戏内物品。此标准支持多种代币类型并能进行高效的批量交易，同时支持原子交易以确保操作的安全性。2022 年推出的 ERC-3525 标准增加了“Slot”和“Value”特征，用于改善代币的识别和可分割性。这些标准已广泛应用于 DeFi、游戏和代币化领域。2024 年初，又提出的 ERC-404 标准以进一步增强了 NFT 的流动性。

SFT 将 NFT 的独特性与 FT 可交换性结合在一起，也就是结合了 ERC-20 和 ERC-721 的特点。SFT 拥有独特的标识符和属性，但在其生态系统内可以与类似的代币交换而不损失价值。它们的优势包括高市场流动性和在金融产品如稳定币和衍生品中的多样化应用。此外，SFT 增强了数字资产的管理和追踪能力，使其更加灵活的同时更具价值。

SFT 的灵活性和可编程性使得它们可以创造针对用户的创新产品和服务，每年都在提升其实际应用。在金融领域，SFT 通过创造 hybrid 型稳定币、去中心化基金、可编程衍生品，以及促进无中介交易等方式带来创新。在 GameFi 领域，它们能够实现游戏内独特物品的创建、交易和奖励。此外，SFT 在数字权利管理中代表独特的所有权、版权和内容访问，促进透明度和高效管理。这种适应性增强了数字权利，金融和游戏体验的创新和发展，推动了 Web3 创新的发展。

SFT 为 NFT 和 FT 的世界带来了新思路

# 什么是 NFT

NFT（非同质化代币）是一种基于区块链技术的数字资产，它可以代表现实世界或虚拟世界中的独特物品或资产。NFT 的核心属性是它们的独特性和可验证性，这使得它们与加密货币，如比特币等有所不同，后者是同质化的，意味着每一个单位都是相同的并且可以互换。每一个 NFT 拥有独特且唯一的标识，两两不可互换，最小单位是 1 且不可分割。NFT 不仅仅是多媒体文件（如 GIF 或 JPEG）的数字形式，它们还充当公共记录，记录与媒体相关的历史信息，类似于画作的所有权证明和真实性证书。

# 什么是 FT

FT（同质化代币）是一种使用区块链技术的数字代币，其特点是每个代币在价值和功能上完全相同，因此可以互换。这种代币的同质性意味着，无论你持有哪个特定的代币单位，它都与其他单位等价，类似于传统的货币系统中的硬币和纸币，其分割性使得它们在支付和交易中更为灵活。FT 通常被用作数字货币，如比特币、以太坊等，也可以用作价值存储或在区块链网络中进行交易和支付的手段。由于 FT 的标准化特性，它们通常能够快速、便捷地交易，提供高流动性。

# SFT vs FT vs NFT

相比于 NFT（非同质化代币） 和 FT（同质化代币)，SFT 更加灵活和具有创新性，它的出现提供了一个介于 FT（同质化代币）和 NFT（非同质化代币）之间的解决方案，旨在结合二者的优点并解决一些特定的痛点。

# SFT 解决 FT 的痛点

### 个性化和独特性：

1. FT 如比特币或以太坊等传统加密货币是完全同质化的，意味着每一个单位都是相同的，缺乏个性化。
2. SFT 允许资产保留一定的独特性或个性化属性，每个代币虽然代表同一类别，但可以承载独特信息或属性。

### 灵活性：

1. FT 通常用于货币或价值存储，功能相对单一。
2. SFT 可以更灵活地应用于多种场景，如会员权益、服务订阅、或者可分割的艺术品等，提供更多层次和维度的使用场景。

### 精确的资产管理：

1. 传统的 FT 不适用于需要精确跟踪不同批次或类型的资产的场景。
2. SFT 可以用于精确管理具有类似属性但需要区分的资产，如库存批次、产地不同但类型相同的产品等。

# SFT 解决 NFT 的痛点

### 高效性和成本：

1. NFT 的交易和管理通常涉及高昂的成本，尤其是在高需求和高交易费用的区块链上。
2. SFT 通过允许同一类型的多个资产被一个代币表示，降低了交易成本和增加了处理效率。

### 市场流动性：

1. NFT 因其独一无二的特性，往往难以快速买卖，影响流动性。
2. SFT 的可分割性和部分同质化特性提高了资产的市场流动性，使得用户可以购买或出售资产的一部分，而非整体。

### 用户入门门槛：

1. NFT 可能对新用户来说概念复杂，特别是在其独特价值和所有权概念方面。
2. SFT 的结构更接近传统的资产和产品，对于普通用户来说更容易理解和接受。

# BenFen SFT 挖矿介绍

## 什么是 BenFen

由 BenFen 基金会发起的新一代去中心化算法稳定币金融系统 BenFen，基于高能 Move 语言构建：安全、高性能、低成本的底层区块链，旨在把“稳定币作为第一公民”这一特征的理想生态系统付诸实践。

作为第一个对稳定币进行原生支持的公链 — — 本分链，BenFen 原生支持稳定币等参与质押（Staking）及支付 Gas 等功能，大大简化了交易流程并降低了成本。

## BenFen SFT 挖矿

### BenFen 作为第一个原生支持 SFT 挖矿的公链，与其他公链项目对比有哪些优势和特点呢？

- 相较于市面上其他的所有公链项目，目前为止，没有一个公链是支持 SFT 挖矿通用性协议的，而 BenFen 链是第一个打破该僵局，原生支持 SFT 挖矿，并且是该技术的第一开发者，拥有核心技术。而市面上的其他公链项目的开发者，如果想要使用 SFT 协议进行完整的开发，这意味着高额的开发成本。这时 BenFen 作为首个原生支持 SFT 挖矿的公链优势便凸显出来，其他开发者可以在 BenFen 链非常简单的开发出 SFT 协议使用，大大降低开发成本。 与同为去中⼼化应⽤发布的 Avalanche 公链相比，创造了更方便的应用部署。
- 在新公链中，无论是以 Aptos 为代表的 Meta 背景公链、以 zkSync 为代表的 Layer2 新公链、以 Aleo 为代表的隐私公链、还是以 Celestia 为代表的模块化区块链。这些都没有涉及到 SFT 挖矿这样的新型概念，以及基于 ERC 404 协议，同时结合 ERC-20 和 ERC-721 的标准化机制，在 BenFen 系统中，只要购买 Long 币，就可以 1:1 兑换 Long SFT 矿机。Long 币是矿机的代币形态，Long SFT 是矿机的 SFT 形态，BenFen SFT 矿机可以两个形态随意转化，使得 SFT 既方便交易质押，同时又有独一无的收藏价值，每个矿机在铸造之时都会有其唯一的编号，不可篡改，不可伪造。这是上述公链所不能做到的事。
- 而相较于 Solana 公链的采用委托权益证明协议（DPoS）的单层区块链，以及 Avalanche 公链提供可互操作、高度延展的生态。BenFen 公链基于高能 Move 语言，构架于权益证明（PoS）共识机制下的 Layer1，原生支持 SFT 挖矿的新型图币合一的代币分发方式，不仅可以在保障资产更加安全的前提下，提供速度更快更稳的 SFT 挖矿模式，而且还内置去中心化且第一个原生支持稳定币参与 SFT 挖矿质押的以及支付 Gas 的高性能公链。
- BenFen SFT 挖矿解决了 NFT 流动性不足的痛点，用户可以直接将 SFT 卖给流动性池。在购买代币时，就可以看到 SFT 的稀有度。由于 Long 币为 BenFen 官方发行，BenFen 官方可作为保持池子流动性积极的自动造市商，参与购买 Long 币，BenFen 将销售矿机所得收益（获得的 USDC 和 BUSD ）100% 全部投入 USDC/BUSD 交易对流动池，增加对应币种的流动性。

### BenFen 创新性地在 Move 语言环境下，将 SFT 形成了本分链的一套通用标准化机制，在未来，越来越多的生态开发者将会采用 SFT 通证进行项目开发。同时，BenFen 将支持用户使用更多稳定币购买 SFT 矿机，所获销售收益均以同样的机制进入 BenFen Dex 为生态提供流动性。

# BenFen SFT 挖矿潜力

当 BFC 价格为 0.1 USDC 时，且 SFT 矿机在全网没有进行任何挖矿行为之下的初始价格为 6737 USDC，购买 SFT 矿机进行质押进去挖矿，到 180 天左右，挖到的 BFC 大概可以和矿机的购买成本价相似，即 180 天动态回本周期。同时，BenFen 初始购买 LONG 币，流动性解锁较低，每天只限售 20 台矿机，10 个在 USDC 池子，10 个在 BUSD 池子。

SFT 矿机由 BenFen 官方发行，BenFen 会将销售 SFT 矿机的全部收益注入 USDC/BUSD 交易对流动性池，增加其流动性。因此 BenFen SFT 矿机挖矿的最大优势就是，SFT 矿机挖矿的收益完全链上公开可查，安全透明，全部收益在注入流动池的同时且根据市场供需平衡关系而波动调整价格，规避任何隐形操作，为用户提供更好的交易体验。

根据当前市场上的 SFT 矿机数量，以及 Long 币在 USDC、BUSD 交易池对中的动态供需和 BFC 的价格来为 SFT 矿机进行定价。由于铸造 BUSD 需要 BFC，因此稳定币的需求越高，BFC 的市场需求也就越大，这在一定程度上可能会促进 BFC 价格的上涨，从而矿机价格也有上涨的可能。

# 结语

随着区块链技术的不断成熟与创新，SFT 的出现无疑是加密资产世界的一大进展。这种新型代币模式不仅继承了传统 FT 的高流动性和 NFT 的独特性，还通过解决现有代币系统的一些痛点，如成本效率和市场流动性，展示了其独特的优势和潜力。

BenFen 的出现使 SFT 的应用不仅限于理论探讨，而是已经在实际的挖矿和质押操作中得到了实际应用。通过结合 ERC-404 的先进标准与多元化的稳定币机制，BenFen 成功地将传统的挖矿概念与现代的金融技术相融合，开创了独特的挖矿模式。在这个更新迭代飞速的区块链世界，每一次技术的革新和参与都是向未来投资的一部分。让我们共同探索这个充满潜力的新领域，携手推动区块链技术的发展，享受挖矿带来的成果和乐趣。

# Kingfisher 专业清算图 助你在加密市场中吃肉

作者：@OBTradeOfficial，@maid_crypto，@0x_Gin

## Kingfisher 是什么？

The Kingfisher 是专为交易者设计的链上数据分析工具，它能够展示高密度清算发生的价格区域。这些区域具有高流动性、剧烈价格波动特性，对交易者来说是混乱的。使用 Kingfisher 清算图，交易者可以进行清算收割交易、盈利性的炒单、准确止损以避免被狩猎、以及在高清算点位止盈。

不难在社交媒体上，发现这样的口碑。Kingfisher 的清算地图计算算法在时效性和准确性上面，是其他同类产品难以比拟的。这是我们选择该产品的主要原因。

## 如何使用 Kingfisher 判断市场赚钱？

下面作者会从 Kingfisher 的 4 个专业图表 手把手解读如何读表赚钱。

1. Liq Maps 清算图：展示实时高倍杆杆清算点位
2. Heatmap 热图：使用先进算法快速准确识别趋势
3. 蜡烛燃尽图：展示超短线多空头趋势信号
4. Gamma 图：基于期权订单流，辅助判断变盘指标

## 01 Liq Maps 清算图

Liq Maps 清算图提供了期货参与者清算的全局视图，可根据之前的价格走势显示即将发生的清算。

X 轴表示资产的价格，Y 轴表示清算的相对强度。

![](static/M8hubsLCroqLs3xzvwCuBX3EsVg.png)

清算条越高，意味着价格对流动性激增的反应越强烈。清算集群越密集、越高，到达该集群的价格可能性越大。当杠杆被清算时，杠杆持有人面临爆仓，且失去杠杆抵押代币；因此市场会产生合力推动价格到达清算点位，促使其爆仓，并瓜分其抵押物或在价格波动中短线投资获利。

## 六种清算地图*：

Thekingfisher 一共提供了六种清算地图

分别用来辅助

scalp（超短线剥头皮交易）和 swing（波段交易）两种交易

![](static/EXJjbz4XFoQD5QxU1Wou3nNas3e.png)

我们最常用的是

**高杠杆清算地图 optical opti 的地图**。该地图是根据未平仓长线高杠杆清算地图用来辅助短线波段交易的。

极端波段高杠杆被清算殆尽时，辅助作用提升的 low ，**低杠杆清算地图**

以及更适合长线操作辅佐的 all，**全杠杆清算地图**

每一次当价格来到一段平台期的时候，清算地图往往会有几种价格分布。

最常见的是下图这样的正态分布。这种横盘阶段。主力很容易会利用正反画门，或者上下插针收走图中双边 cluaster（密集清算区间）中杠杆玩家的资金。尤其是在周末的行情当中，吃赌徒肉的钓鱼策略，有着极高的胜率。

![](static/YCfgbUJAQoToKnx1QvduTgkssVc.png)

此时我们便可以根据清算地图，判断出，这个位置的波段交易高胜率区间。这个策略的准确性非常高。我们不难从社区中的正反馈呼声中得到验证

在另外一种常见 cluster 位置，高杠杆玩家更倾向于一侧的情况下。往往后续会出现清算杠杆行情，对应清算位置会有被插针的风险。

![](static/VsDOb7lk6oeZD1xioTQuvdZvs2g.png)

值得注意的几点：

- 价格走势往往受到密集清算集群的吸引
- 清算往往标志着阶段性顶部和底部
- 具体情况灵活结合不同的清算地图，可以获得更高的胜率

![](static/FACnb3L0Pol3mkx70ExuHFYwsHf.png)

用户可以调整图表上方的筛选器以显示不同交易所、代币、清算的杠杆强度。同时配合下方 **LiqRatio 图****，多空比地图**观察不同链的多空比。

![](static/JJVcbsrwBodhSpxKpBTuopvzsnd.png)

举个例子，在 2024 年 6 月 12 日，出现了大量高倍做空订单，其清算价格集群在图表上一路了然。遵循“清算集群越密集、越高，到达该集群的价格可能性越大”的逻辑，市场合力可能会清算红框中的订单。次日 BTC 价格突然涨至 $69999，完成了红框中最高的清算条，并且在这个位置形成阶段性顶部。作为顺势交易者，若在彼时买入或做多，即抓住了链上机会。

![](static/F9ZybghaSoYI19x6krAuXFhYsQe.png)

推文来源：[https://x.com/OBTradeOfficial/status/1800715103295439239](https://x.com/OBTradeOfficial/status/1800715103295439239)

## 02 Heatmap 热图

Heatmap 借助其先进的 Z-score 值算法和热图可视化功能，使用方法和清算地图类似，但是因为引入了统计学算法。对于点位更精准，尤其是当集中清算区域变成紫色的时候，代表这个位置的清算强度很大。这一点在清算地图中无法很好体现。

![](static/J5mlb9IsXoIu3WxaCTNup21jsGS.png)

## 03 蜡烛燃尽图 与 CVD 指数

**蜡烛燃尽指标**（major 主要/minor 次要；long 多头/short/空头)信号可以显示当前趋势的状态，尤其是当趋势失去势能并结束时。

**累计交易量增量 CVD**（cumulative volume delta）

帮助准确了解买入/卖出量是如何被对收盘交易者吸收的，识别**不同价格下买卖方的成交强度**。

当前市场中，交易量仍然是高倍杠杆交易者“赌徒”参与的最重要指标之一。了解市场买卖动态的常用方法是(T&S)交易生成时间和交易信息。此时 CVD 就派上用场了，它是成交量增量（volume delta）的累计，即在特定时间段内**进入市场的市场销售量**与**市场购买量之间的差值**。

CVD 主要可以告诉我们两件事：

1. 买入和卖出订单之间的交易量**不平衡**，因此可发现特定时间内 哪方订单流占主导地位。
2. 主导订单/大额订单对价格的影响**。**

因此，我们可以通过 CVD 检测到市场中 FOMO 买家/卖家、追高追低者和激进交易者的影响。简而言之，这类特殊的市场参与者无意中会在低点卖出，在高点买入，也恰恰导致他们的杠杆被清算。我们可以加入“清算他们的行列”，即利用此影响指标在超短线操作中获利。

![](static/LOSwbtHD1o9NaHxkqFnudh7CsQg.png)

## 04 Gamma 图*

**GEX+ 图**

通过分析 BTC 或 ETH 的期权订单流，模拟交易商的仓位，并推断他们的 Gamma 和 Vanna 风险敞口。

通过绘制如下的 delta 值（x 轴：VI 隐含波动率；y 轴：代币价格），可以观测交易商的 delta 值及对冲每一美元的升高或下降所需要的成本。

Delta > 0（蓝绿色）→ 交易商倾向于**逆势交易**以保持对冲

Delta < 0（紫红色）→ 交易商倾向于**跟随价格走势**交易以保持对冲

Delta = 0（透明）→ Delta 已对冲，价格可能**即将发生重大转变**

![](static/QUIPbVpwhod12KxfmAKux2gNsRb.png)

**GEX 图背后逻辑**

大部分期权交易量通常由寻求非定向押注的专业交易员/交易台承销。他们充当流动性提供者，且倾向于做**动态对冲其库存**的交易，这些交易行为对价格走势有直接影响。

他们通过出售期权并收取相关溢价来赚钱，不对价格走势做方向性押注（和赌狗不一样），因此对于期权交易商而言，重要的是**对冲头寸**。

交易商会采用 Black-Scholes-Merton 模型评估风险，并试图模仿隐含波动率 IV（implied volatility）来匹配未来的实际波动率。

**Gamma 曝光**

通过买入/卖出来对冲 Gamma 风险，从而使交易商的预期回报曲线趋于平缓。

- 交易商做多 Gamma → 价格上涨时卖出，价格下跌时买入 → 稳定价格，软化价格波动
- 交易商做空 Gamma → 价格上涨时买入，价格下跌时卖出 → 破坏价格稳定，加剧价格波动

**Vanna 曝光**

期权交易商 Vanna 敞口代表交易商在不同隐含波动率 VI 背景下的期权投资组合敞口。总结如下：

## ARB 链游戏资产 迁移 ➡️ RON 链

CBT 轮基于 RON 链，与原先 ARB 链的 Lumiterra 可能产生游戏装备价格差异，或许有套利空间。同时原先 ARB 链上的高阶装备迁移至 RON 链后 在本轮早期游戏中可能有一定优势。

## 方法一：**持有图腾迁移**

对于 ARB 链原先持有图腾玩家，只需将任意品质图腾发送 1 个至官方地址（0xE513924EE8F63dD5Ea15F457bDd08b35aDFBAbA9），同时**即可获得 Ronin CBT #1 的资格**。该账号下所有链上资产都会迁移至 Ronin（请确保发送账号与游戏登录使用的钱包地址一致）

1. 玩家若持有完整图腾，使用登入游戏的钱包地址中（非 sodium 钱包）直接发送图腾到指定地址即可参与
2. 若玩家持有图腾底（base）和顶（roof）需要将图腾发送到 tg bot （@sosotribe_bot）中，按照步骤合成后，发送回登入游戏的钱包地址中，再进行完整图腾的转账即可参与。
3. 若玩家的完整图腾在 tg bot（@sosotribe_bot）中，先使用此 bot 将图腾发送到登入游戏的钱包地址中，再次发送图腾到指定地址即可参与

注意事项：

1. 为图腾顶（单独发送此图腾 无法获得资格）
2. 为图腾底（单独发送此图腾 无法获得资格）
3. 为完整图腾（单独发送此图腾即可获得 ronin cbt1 的迁移测试资格）

图腾的“ABCDE”均为不同的属性品质，任一品质均可参与，不限制属性。但图腾合成需要同属性的 **Roof** 和 **base** 各一个才可合成。

![](static/Tihzb1Usco59bvx1Sm7uhxoRsQg.png)

Ronin CBT#1 结束后，图腾将原路返回。

官方将于 **7 月 13 号 15:00 HKT** 进行快照，用户需在 **7 月 18 号 15:00 HKT 至 7 月 20 号 15:00 HKT** 之间完成迁移（官方提供工具进行 bridge）。

官方将在 Ronin CBT #2 及后续时间继续迁移其他用户及对应资产。

迁移的用户可在 CBT #1 **开服后第 6 天**进入。

# MPC 单元状态是什么？

v1.2

---

## 什么是已验证状态？

当用户登录到钱包账户并且在本地设备中验证过 MPC 单元后，OpenBlock 将自动识别用户身份。当用户在一个新设备上登录钱包账户时，在默认情况下，该设备是未经认证的。此时，OpenBlock 假设是一名黑客正在使用伪造的身份信息登录该设备进行操作。本地 MPC 单元必须显示在该设备中以使该设备完成验证。OpenBlock 提供两种方式以显示该本地 MPC 单元。该两种方式均需要有账户访问权限的真实持有人的身份信息。第一种方式是从一个已验证设备上远程同步本地 MPC 单元。第二种方式是导入一个备份的本地 MPC 单元。两种方式均需要向 OpenBlock 证明设备的身份并验证该设备。

如果用户不慎丢失所有的验证设备和备份的本地 MPC 单元。OpenBlock 不能盲目地为该用户破例识别其登录账户的新设备，这可能是是黑客尝试破解账户的一种欺诈手段。为解决该种情况，OpenBlock 推出重置流程，旨在让账户的真实持有人可以在新设备中登录账户。重置后，用户可以恢复对钱包的访问、获得新的 MPC 单元并完成设备验证。

## 每种设备验证状态间的区别是什么？

### 未验证：

1. 没有完成 MPC 单元验证或者第一次登录的任意设备。
2. 该设备先前已完成 MPC 单元验证，但 MPC 单元已过期，需重新验证。

### 已验证：

1. 已完成 MPC 单元验证的设备。

## 什么时候需要用到何种验证方法？

1. 只有当存在已验证设备时，设备同步功能将启用，用户可以选择列表中的任意设备完成查看、选取和同步等操作。
2. 如果当面页面没有任何可供选择的已验证设备，您只能通过导入可用的已备份的 MPC 单元文件来完成新设备验证。
3. 如果当前页面没有任何已验证设备或可用备份，您将无法通过上述任何一种方法完成设备验证。您必须重置 MPC 单元来恢复账户访问。

MNT：200,000 MNT (Bybit 的 Mantle 公链代币，总值约二十万 USD)

## 参与方式

### 活动时间

6 月 5 日 – 7 月 2 日

### 登录方式

浏览器绑定 Twitter，进入游戏后先做基本任务，然后挖矿石水晶，升级打 BOSS 赚取积分奖励！

## 游戏攻略

### 一．安装游戏插件并登录

1. 打开 Chrome 浏览器进入插件商城，搜索 xmetacene.
   点击“添加到 Chrome”，等待安装完成。
2. 充值 MNT：进入 [https://openblock.com/#/download](https://openblock.com/#/download) 安装 OpenBlock 钱包插件

![](static/Ymbgb2tA8oG3Zhxk1zVu9ohxsQe.jpg)

### 二. 填写邀请码，开启初始挖矿

邀请制注册，邀请码：lofFRBfEqr

打开 xMetaCene 插件，你会看到屏幕右边有一个邀请码填写框。输入邀请码后，会进入游戏页面，先在任务栏完成基本任务，获得水晶和 gas，其中有一个任务是要求钱包有 1MNT，大概价值 1U，做完任务之后可以 Swap 回去

![](static/J2L4bWbfAoIzmUxGiz0uN3ttsbf.png)

![](static/XxmZbtXpCox2Akx8oqKuvN6yswe.png)

### 三．升级小羊 & 解锁男女机器人

除了提升算力之外，解锁更多的矿工也是关键所在。游戏中有两位矿工等待你的召唤：一位男矿工和一位女矿工。

完成任务之后，解锁男女机器人并升级小羊，男女机器人是不需要 12h 唤醒的，但需要喝饮料才能高效挖矿。 小羊需要每 12h 唤醒一次，我们拿到水晶优先去升级小羊，随着小羊等级越高，每小时产出也越高

![](static/Xltxba402oIVD4xEVrfuRRhGsQc.png)

### 四：打 BOSS

主页的 Battle 页面，每天会刷新一只 Boss，分配相应的水晶即可瓜分星星币奖励，这也是最主要的打金来源。每天的 1000K 代币由投入水晶的玩家按比例分配，越早参与竞争越小

![](static/RSlvbPOdnouzImxttvguugL3sUh.png)

### 五：星星抽奖及代币兑换

在 Campaign 界面，有 Event1 和 Event2，这里也是消耗我们打到的星星的地方。 Event1 是星星抽奖， Event2 是直接兑换代币，也就是把打到的金变现。

![](static/OkCmbw9i4oAgi6xEkwku7NmNsye.png)

xMetaCene 游戏内一共有三种资源：水晶、星星币、药水

水晶：每日挖矿获得、用于提升机器人等级、打 boss 消耗

星星币：通过打 boss 获得，变现的唯一挂钩资源

药水：任务获得，用于恢复男女矿工挖矿效率

## 资源分配攻略：

前期水晶优先提升小羊等级，药水优先分配给男矿工。等到三个矿工等级都明显出现瓶颈了再主要投入打 boss。星星代币建议先不换，等之后玩家多了出攻略再决定如何分配

# OB Trade 上线防 MEV RPC 功能，有效避免三明治套利攻击

## 闪兑过程中，您是否有**花同样的钱，仅兑换出更少的币**的经历？

看似是“在滑点范围的正常波动”，实则可能“遭遇 MEV 三明治攻击”

![](static/I95Jbl0FOoTFUgxb31SuzldEsRf.png)

## 什么是 MEV 三明治攻击？

攻击者通过扫描区块链的内存池，找到高价值交易，并抢先于用户之前进行交换操作，支付更高的 gas 费用，确保攻击者的购买交易优先上链。当攻击者购买后，使此代币价格上涨，导致用户需要支付更多才能完成交易。当用户完成购买代币后，攻击者再出售低价买入的代币，从中赚取差价。

**被攻击的直接影响：** 用户花同样的钱，购买了更少的币。理论上如果用户设置 50% 的最高交易滑点，若遭遇 MEV 攻击，次笔交易将有可能仅获得预估获得代币数量的 50%。是否被攻击跟 Gas 费、交易金额、池 TVL 无直接关系，MEV 攻击的判断逻辑是有利润就夹，所以无论进行小额还是大额交易，同样有可能被攻击。

![](static/OXJ8bqPX3obahjxirhWuMh87sqc.png)

## OBTrade 防 MEV RPC 功能，为交易者保驾护航

OBTrade 现已支持 Flashbot 防 MEV RPC 功能，有效避免用户的交易被恶意地夹在攻击者的两笔交易之间，被“三明治”攻击。

**Flashbot 如何保护交易者？** 用户将交易信息发送到 Flashbot 网络，Flashbot 将多笔用户交易捆绑在一起，有效保护了交易隐私信息，并直接发送给矿工而不是发送到公共内存池（mempool），防止交易被攻击者抢先交易或遭遇 MEV 三明治攻击。

## 如何启用防 MEV RPC 功能？

1. 进入 OB Trade 官网 obtrade.openblock.com，并连接钱包 。推荐使用配套的 OpenBlock 钱包 [https://openblock.com/#/download](https://openblock.com/#/download)
2. 选择好需要跨链闪兑的代币后，点击下方“**Add RPC**”即可启用功能。此 RPC 节点将添加至钱包内。
3. 请注意，如果需要切换至公开节点，则可在钱包内切换。您也可以直接将下方 RPC 节点手动添加至钱包：

# OpenBlock DID 短域名

v1.0

---

## 什么是 Web3 短域名？

Web3 短域名是以去中心化的形式持有在您的钱包中的，并可用于与其他 DApp 和智能合约交互。拥有 web3 短域名有很多好处。相比于一个难以记住的 42 个字符的传统加密钱包地址，web3 短域名直接的好处就是您可以拥有一个更短、更容易记住、更不可能在支付或收款时出错的地址。例如，相比在每笔转账前多次确认一个 42 个字符的转账地址 0x55add7893w8edd9qq9023fqdz934xx1fc0azde7c，您可以轻松地向对方的短域名“alice.eth”发送加密转账。同时，web3 域名也是一个您独享的 NFT，它具有唯一性和互换性。您的 web3 域名将是您在 web3 世界中用于社交互动的数字身份。

Web3 短域名与 web2 传统域名系统 (DNS) 有着很大的不同。在 web2 里，由于集中化，域名所有者对其域名的控制权是很有限的。但在 web3 领域，得益于区块链技术的加持，web3 短域名所有者对自己的域名拥有着最终的控制权。

基于 web3 不可阻挡的蓬勃发展，人们渴望尝试 web3 短域名带来的各种优势和便利。现在 OpenBlock 钱包推出了支持 SpaceID, ENS, .bit, Twitterscan 和 AptosPassport 短域名的功能，用户可以在 ETH、BSC、Polygon、Tron 等链上使用短域名功能。有了这个新功能，您将有更棒的 web3 使用体验。

## 如何注册使用短域名？

1. 进入 .bit 短域名官网 https://www.did.id/
2. 点击右上角的 “**App**”, 进入钱包连接页面，点击 “**我的**”，即会出多种连接环境，这里以选择 ETH 环境作为例。

![](static/boxusiWarEJKZGlIbLPXsy3RVHc.png)

![](static/boxusKypUhxpHHs2jIqLuUCsUrb.png)

3. 回到 “**查询**”界面，在**搜索栏**中编辑输入想注册的短域名（此处以随机数字为例），点击 “**搜索**”。

![](static/boxusuLuj4J6asPj5xNzgLNkFVd.jpeg)

1. 点击 “**注册为普通的 .bit**”。

![](static/boxus3bs4mVBFpovLA6VRIVDrlf.jpeg)

4. 在此处选择**注册年限**并支付注册费及质押金（注册年限最高为 20 年，最低为 1 年）。点击“**注册**”。

![](static/boxusjBO3KlS9lAxchr9EHez7Dd.jpeg)

5. 转入支付页面，选择**支付方式**（此处以 ETH 为例）。点击“**支付**”，并在 OpenBlock 钱包端点击“**确认**”。

![](static/boxushiCCcNA9GMPetIlz0bAAzc.png)

![](static/boxusdWgy2d4aL8R2qhAZU4sNsd.jpeg)

6. 支付成功后，等待约 15~30 分钟的确认过程。待页面刷新后显示短域名注册成功。

![](static/boxuszg32QEAaGFr5OGR2CzZ4gd.jpeg)

7. 再次回到 “**我的**”界面， 点击** .bit 别名**栏内的**“未设置**”，点击 “**立即设置**”。

![](static/boxusK5n6cgnilgwWUEXt5P2fbb.png)

![](static/boxusC23cVVe0AlinnfBRrHv4rh.png)

8. 阅读提示，设置 .bit 别名需要占用链上储存空间并**冻结 201 CBK**。请确钱包余额充足, 并点击“**保存**”。

![](static/boxusS4LkTMRdd4Bz4m5mLJ776d.png)

9. 连接 OpenBlock 钱包，主页将弹出 “现已支持显示您购买的 Web3 域名” 信息提示。此时，点击“复制公钥地址”按键时，会出现 “管理 Web3 域名”。点击 “**管理 Web3 域名**”。

![](static/boxusYgM00ZHOLy27cOkNgqJWUg.jpeg)

10. 点击“**立即映射**”，选择域名平台，并完成映射过程。

# OpenBlock MPC 钱包使用手册

v2.2

---

只需要一分钟和一个电子邮箱，OpenBlock 将带您打开 Web3 的世界。您不仅可以使用 OpenBlock 强大并可靠的非托管式 MPC 钱包储存并接收区块链资产，也可以用它登录海量的 Web3 应用程序，畅游 Web3。

## 什么是 MPC 钱包

安全多方计算 (MPC ) 是一种数据加密协议。该协议在执行指令前需要同时获得多方同意，仅有任意一方单独同意不足以获得钱包控制权。MPC 钱包采用了此协议，有效避免了单点验证失败的风险。

## 为什么要用 MPC 钱包

MPC 钱包为用户提供了更优秀的安全保障。目前，黑客在 MPC 技术上面临着更大的挑战。为了获取用户钱包的控制权，黑客必须在多个操作平台和地点同时攻击储存 MPC 单元的各计算方，难度远高于攻击单个验证点。

## 为什么选 OpenBlock

OpenBlock 钱包的初始化会分别在用户本地设备端、OpenBlock 服务器端及第三方冷库端独立生成一份 MPC 单元。当三份 MPC 单元中的任意两份 MPC 单元经过运行多方安全计算（MPC）协议后完成签名。此 2-3 门限签名管理方案不会生成任何完整私钥，最大程度降低钱包单点失效的风险。若用户失去对钱包的所有访问权限，OpenBlock 社交恢复功能将激活专属钱包的恢复 MPC 单元，并帮助用户找回钱包控制权。OpenBlock 钱包注册便捷且功能强大，支持用户使用 Google、Apple 账号进行第三方登录，支持主流短域名绑定功能，同时还已经上线支持 gamefi 道具、收藏品、活动通证等 NFT 资产，便于用户参与空投、交易活动，以及展示收藏品等。

## **步骤 1: 创建一个 OpenBlock 账户**

1. 点击 OpenBlock 主页右上角的 **创建账户**。
2. 输入您的电子邮箱作为您的账号。

![](static/boxusjhvxafeFGvEBHpalL9R5of.png)

3. 点击 **继续**。
4. 输入您电子邮箱里收到的 6 位验证码。如没收到请查看垃圾邮件箱。
5. 设置一个 8 到 20 位字符的强密码，其必须包含至少一个大小写英文、数字、以及一个特殊标点符号 (!,+#,$,%)。
6. 点击 **下一步**。
7. 设置一个 6 位数字的支付密码用于转账和恢复钱包等操作。
8. 现在您可以看到 OpenBlock 的控制面板了。开始您的 OpenBlock 探索之吧！

![](static/boxusOt98ZTe4ZZo7esMKZTY4uc.png)

## **步骤 2: 用****双重****验证和恢复邮箱来保护您的账户。**

2FA 和恢复信息可以起到保护您的账户的重要作用。OpenBlock 为您提供了很多安全功能，以满足您对安全方面的需求。我们建议用户添加谷歌验证来加强账号安全。

# TON | Catizen : TON 生态最火链游 - 史上最全零撸教程！

## 游戏链接

[https://t.me/catizenbot/gameapp?startapp=rp_6760859](https://t.me/catizenbot/gameapp?startapp=rp_6760859)

## 更多 Ton 生态 tapps 研报请锁定 TappsDaily 官方推特：

**[https://twitter.com/TappsDaily](https://twitter.com/TappsDaily)**

### **以及更多 Defi 投研账号：**

**[https://twitter.com/Mumu__131](https://twitter.com/Mumu__131)**

## 游戏介绍

Catizen 是一个基于 Ton（Open Network）生态系统的链游

1. TON 生态官方应用商店 Telegram Apps Center (TApps Center) 的排名位居榜首。
2. 团队与 TON Fish 合作，由 @tapfantasy（一个高质量 rpg 游戏） 驱动孵化，结合了元宇宙、Game Fi 和 AI 的空投项目。
3. 据说获得了 ton 基金会官方投资，该信息在官方 grant 名单下没查到。
4. 官网纰漏与小米有合作
5. 600 万电报用户参与项目，16000 满足挖矿门槛的重氪用户，项目方收益已经超过 1000wu。

允许玩家通过养成猫咪角色来参与游戏，赚取游戏内的积分代币来升级猫的等级。

此外，Catizen 游戏内还包含了挖矿机制，玩家可以通过游戏内的活动来获取代币奖励，而无需直接投资，这便是典型的 “零撸挖矿”。

## 代币详情:

1. 主要代币以猫爪形式呈现：$wCATI 🐾。获得方式：在挖矿活动期间用 $Fish 币挖，完成任务等可获得 $wCATI。目前 Catizen 首轮获得 $wCATI 的挖矿活动已于 5 月 8 号结束。当前游戏主要以收集积分代币 $vKitty 为主，积分币 $vKitty 数量越多，猫的级别越高，后期可能空投的分配比例越大，也可能会有兑换 $wCATI 的利好。
2. $Fish 🐟代币用于购买加速和升级，也用于捕鱼（简称鱼币）。玩家可充值 $Fish 来进行钓鱼，获取大量积分 $vKitty 来提升猫的等级。在上一轮的挖矿活动获得正式代币 $wCATI，只有猫达到 110 级以后才能进行挖矿操作。如果氪金玩家想要在一天之内冲到 110 级以上参与早期挖矿，需要至少 1000u 及以上。

第四个代币即将发布

![](static/IzDBbIoI2oDbCKxM5I7uR7Bjsvc.jpeg)

## Tokenomics:

- 游戏由一个纯华人团队推出，将 $FISH 代币的价格推高了 45 倍。
- 该项目计划构建一个完整的生态系统，其中包括 $wCATI 代币，35% 的代币(10 亿代币)被用于生态系统和空投。空投代币总价值高达 1.15 亿美金。

## 游戏机制:

- 在 Telegram 应用游戏中，玩家将获得代币 $wCATI，未来可以出售。
- 玩家可以通过支付 TON 代币来更快地升级。
- 玩家需要升级猫、捕鱼和收集积分币 $vKitty 以获得更多代币 $wCATI。
- 分配方式：可能根据游戏中的排名、积分币等分配空投。

[t.me](https://t.me/catizenbot/gameapp?startapp=rp_6760859)

## 玩法教程：

### 充值 TON，升级 Catizen：

1. 需要一个 Telegram 账号。创建并使用 Telegram 内建的 TON Space 或 人气比较高的第三方 Tonkeeper 钱包。

⚠️ 如果使用官方自带 TON Wallet，充值 3000u 可参与 50% 的年化，并且部分用户无法正常打开官方钱包，提币的时候需要进行 KYC 认证。

2. 使用该链接 [https://t.me/catizenbot/gameapp?startapp=rp_6760859](https://t.me/catizenbot/gameapp?startapp=rp_6760859) 进入游戏，进行猫咪的配对升级，想要获得高阶猫咪赚取更多收益的玩家，所有套餐首充都有双倍奖励，推荐充值套餐 💲26.99，够钱开启自动收集猫咪完成升级模式。点击 “Auto” 开启自动模式，会花费 3000 多鱼币，剩下的鱼币可用来钓鱼，获得积分币 $vKitty 进行猫咪升级。而在挖矿活动开启期间，代币 $wCATI 的挖矿速度取决于合并的猫的数量和等级，等级越高挖矿越快。

**“升级最快的方式就是充钱买鱼币，然后在 feed 界面升级猫咪，每日任务，随机任务都很划算，都值得一做。下文详解”**

![](static/YxNWbOTFRoB8rVxAooVu9Typsge.jpeg)

3. 除了部分 tg 账号打不开，并且完整功能需要 kyc 这个劣势之外，官方钱包目前最大的优势可以直接充值波场 trc20 的 usdt，自动转换为 ton usdt，然后在 tg 自带的中心化钱包里面买成 $ton，然后提到 tg 的去中心钱包 tg space 钱包，进行游戏游玩。提币也可以直接提成 trc20 钱包的 usdt 去交易所。因为目前大部分交易所 ton 代币充提币都有点问题。
4. 无需 KYC 认证，使用 Tonkeeper 钱包充值 TON，游戏内点击 Ton connect，选择 Tonkeeper 钱包，进入下载页面：[https://github.com/tonkeeper/tonkeeper-web/releases](https://github.com/tonkeeper/tonkeeper-web/releases)，苹果电脑选择 .dmg 格式的安装包下载。

![](static/MTCDbb1GwoldUIxcGYPuvhvDs5E.jpeg)

5. 安装 Tonkeeper，复制钱包地址，从 Gate.io 上购买 TON 币后直接转入。

⚠️ Gate.io 无需 KYC 认证，支持 TON network 进行转账。而 OKX 购买 TON 需要 KYC 认证。

![](static/GBL2bLmj3oICCGx0n83uIJvrscf.png)

## **$Fish 鱼币的玩法：**

1. 点击首页“Feed” 喂养按钮，这是升级猫等级的地方，在玩家当下最高的两个等级，可用鱼币直接购买升级，建议：等级 10 级以下花费鱼币数量不多，可以直接购买，但是超过 10 级，每一次鱼币的购买消费都是次方乘积，非常不划算。

![](static/E8VCbvnllowNIdx7yvxu3TXAsYg.jpeg)

2. 点击首页左上方“Fishing” 钓鱼按钮，这是获得鱼币、积分币以及其他奖励的地方。一次钓鱼消耗 84 鱼币，钓出来的奖励随机模式，可以是鱼币，但是大部分是积分币 $vKitty，所以这也是用来升级猫的最划算的方式之一，鱼币钓鱼获得大量积分币，用积分币在“Feed”处进行升级。

![](static/DbWAbJA7QohTcix1WTGuHUrBsVe.jpeg)

## Quests 每日任务增加鱼币

游戏首页点击「Quests」，在 catizen task 完成每日签到、TG 会员注册、以及关注推特等交互，可获得鱼币。在 Achievement 成就栏可完成累计签到、累计充值、累计邀请以及会员福利的奖励。

![](static/JeHmbxcqPoJp5hxIjYRu5CG4spd.jpeg)

## 游戏加速:

- 有各种加速器可以提升矿工等级。
- 在“Shop”部分可以用 TON 代币购买额外的鱼币。
- 在“加速”部分，可以通过支付少量鱼币来提高新小猫的发行速度。
- 等级高了不适合直接用鱼币升级猫，可进行钓鱼，获得大量积分币 $vKitty 来升级猫。
- 通过支付积分币 $vKitty，可以在“Generate”按钮上获得额外的猫。
- 在“Feed”部分，可以用积分币 $vKitty 购买所需等级的猫。
- 在“Fishing”部分，可以捕捞 $Fish 鱼币和积分币 $vKitty，获得奖励，包括挖矿速度或其他奖励。活跃的渔民将参与排行榜，并获得额外奖励。

## 重点回顾：

1. 空投：游戏开启时会持续空投猫咪。
2. 鱼币：用来钓鱼是最划算的升级猫咪方式。
3. Boost：有空时点击，提高赚钱速度。
4. Quests：完成每日任务获得鱼币。
5. Shop：购买猫咪时注意 CP 值。
6. TG 会员：邀请朋友和创建 club 等会有鱼币奖励。
7. 投资建议：理性消费。

## 融资背景

Catizen 是一个纯华人团队，由耀腾投资基金的 David 作为其 CEO，其融资背景包括：Mantle, Ton，Mirana，NGC，小米，Secondlive 等强大的头部团队。https://www.catizen.ai/

![](static/ETd6bXiakoTlENxUm2MuHsdcsjh.png)

## 另世玩法，增加积分币

当然，还有一种方法可以赚更多的积分币 $vKitty，从 Catizen AI 游戏小程序进入https://www.catizen.ai/game，有许多解压游戏通关可积攒积分币。

# 为什么提示交易正在进行中?

v1.0

---

当您在以太坊网络或 EVM(以太坊虚拟机)兼容网络上提交交易时，您的 Gas 价格是对网络算力的出价，以便矿工能更快处理您的交易。如果您提交的 Gas 费用较低，您会发现您的交易处理时间较长。关于如何设置 Gas 费用与交易时间的平衡的信息，请查阅 Etherscan Gas Tracker，或其它您日常使用的区块链网络的 Gas 追踪器。

此外，存在交易出错导致交易冻结或交易哈希长时间显示交易正在进行中。


# 为什么要支付交易费或 Gas 费?

v1.3

---

在任意区块链上，交易费或 Gas 费是指在网络上执行交易所需的成本。加密矿工根据处理智能合约和其它交易所需的网络算力的供需情况来设定 Gas 价格。Gas 的价格以该链底层代币的极少部分表示，单位为 gwei。例如，当您使用以太坊网络时，Gas 费以少量 ETH 支付。请点击该链接查看以太坊网络 Gas 费的历史数据。

比特币和以太坊是两个 Gas 费用较高的区块链。您可以使用其它类似的区块链网络花费更少的 Gas 费发送代币。此外，Gas 费用是动态调整的，一般情况下，区块链网络越拥堵，Gas 费用越高。这是因为加密矿工会优先打包高 Gas 费用的交易。如果在网络拥堵的情况下，您希望尽快完成交易，您根据下文提示了解如何自定义调整 Gas 费用。您也可以在 ETH Gas Tracker 等网站实时查看 Gas 费用，并决定是否在当前 Gas 费用下完成交易。

## 请按照以下步骤自定义 Gas 费：

1. 登录 OpenBlock 账户并点击官网右上方的“**钱包**”。
2. 在左侧菜单栏，请选择您希望接收币种对应的转账网络（如：以太坊）。
3. 请点击“**设置**”按钮（个人钱包页转账按钮上方的齿轮按钮）。
4. 启用“**高级燃料设置**”，然后返回个人钱包页。
5. 点击“**转账**”，输入您的**收款地址**和**转账数量。**
6. 点击“**交易费**”，然后您可以自定义调整 Gas 费用。


# 什么是 HD 派生？


---

为了更好的用户体验，OpenBlock 持续在 MPC 钱包的体验和安全性上做着研究与升级。OpenBlock 钱包现已支持 HD 派生，将其便利性与 MPC 的安全性结合，使得用户既能享受到便于管理和恢复的 HD 结构，又能受益于 MPC 技术的高安全标准。

*只有新创建的子钱包能使用 HD 派生功能。

# 1. 什么是 HD 派生

HD 派生（Hierarchical Deterministic Derivation）是一种加密货币钱包技术，允许从单一的种子（通常是一串单词或数字）生成一系列密钥对（公钥和私钥）。这种技术的核心是 BIP32（Bitcoin Improvement Proposal 32）标准，它定义了如何使用一个主种子来创建一个层次化的、有序的结构，从而派生出多个子密钥。每个子密钥都可以作为独立的钱包使用，这样用户只需记住最初的种子，即可恢复访问所有相关的账户和资金。

**主私钥和主公钥**：主私钥是密钥树的根，所有其他的密钥（私钥和公钥）都是通过它派生出来的。

**派生路径**：通过定义不同的派生路径，可以从主私钥生成不同的子私钥和子公钥。这些路径遵循一定的规则（如 `m/44'/0'/0'/0` 表示的路径），其中每一层都可以代表不同的意义（如币种、账户、地址等）。

**扩展密钥**：每个私钥都可以生成对应的公钥，而且由于加密算法的特性，父公钥可以派生出子公钥，而无需知道子私钥。这意味着可以公开父公钥以生成接收地址，而不暴露对应的私钥。

HD 派生的主要好处包括：

- **增强隐私**：通过为每次交易生成新的地址，避免了地址重用，从而增加了用户的隐私。
- **便于备份和恢复**：只需备份初始种子，即可恢复访问所有派生的密钥和地址，简化了备份过程。
- **组织结构**：允许按照需求创建复杂的子账户结构（例如，不同的子账户用于不同的用途），便于管理。

# 2. MPC 钱包的 HD 派生如何实现

MPC 钱包利用多方计算技术来分散存储私钥，从而提高安全性。在 MPC 钱包中实现 HD 派生涉及到如何在不直接暴露私钥的情况下，通过多个参与方的计算合作，生成 HD 派生路径下的新密钥对。

OpenBlock 现已将 HD 派生技术融合

- **子钱包密钥派生**：在用户生成子钱包时，将使用主钱包的主种子，通过 MPC 协作计算出 HD 派生路径下的子密钥对，完成对子钱包的初始化。密钥派生步骤同样通过 MPC 协议进行，确保在不泄露私钥片段的情况下完成密钥的生成和使用。
- **使用和管理密钥**：OpenBlock 的用户只需备份一份 MPC 单元。就能导入整个密钥树上的所有地址，大大简化了备份和恢复过程。


# 什么是 MPC (安全多方计算)和 MPC 单元?


---

## 什么是安全多方计算( MPC )?

MPC（Multi Party Computation）安全多方计算是基于密码学的协同计算框架的隐私计算技术。可以理解为多方各自有输入密钥来一起完成计算任务（签名、交易、授权），期间可以保证各自的密钥不会泄露。MPC/SMPC 作为一种数据加密协议，在执行指令前需要获得多方同意，其中任何一方都不能访问其他方的数据。

**MPC 钱包，即将多方安全计算技术应用于区块链钱包创建过程的一种钱包类型，它与其他钱包最主要的区别，在于其私钥生成方式的不同。**MPC 钱包中所有账户的创建过程都运行在一个可信执行环境（TEE）中，私钥分布式生成（DKG, distributed key generation），直接在用户端和服务器端分别生成不同的私钥分片，多方安全即体现在这里，私钥从一开始就是分片，完整的私钥从头到尾都没有出现过，所以也根本不存在私钥丢失、被盗等可能性，大大降低了用户自己管理钱包的风险。本文重在介绍 MPC 钱包技术，为了您能清晰了解这项技术及其未来发展前景，我们从**分布式私钥生成**以及**门限签名**说起。

1. **分布式私钥生成（DKG, distributed key generation）**

分布式私钥生成旨在解决一个问题：摆脱对可信的权威机构的依赖。

很多密码学逻辑在加密过程中都需要一个初始化的私钥，而这个私钥一般都由大家信赖的第三方机构生成管理，这就存在单点故障和私钥托管等安全问题。分布式私钥生成通过多方参与，计算共享的公钥与私钥集，则可以摆脱对可信第三方的依赖。

1. **门限签名方案（TSS, Threshold Signature Scheme）**

门限签名方案是一种 MPC 密钥管理方案，用于分布式密钥生成和签名的密码技术。

门限签名特点是一个签名一定是由一个私钥产生，然而这个私钥不会被任何人完整掌握，而是会以某种方式分成很多碎片，这些碎片可以被多人同时持有，然后通过 MPC 协议，保证这些碎片不需要全部被拼起来就可以直接产生一个合法的签名。

OpenBlock MPC 钱包实现了 2-3 门限签名方案 (TSS)，将 MPC 单元分解为三个片段并本地生成到三个计算方（用户本地设备、 OpenBlock 服务器和冷储存设备）。每个设备都收到三个 MPC 单元中的两个，当它们互相组合或解析时，就可以访问钱包并验证交易请求。因此，用户不再需要将 MPC 单元保存在某个单一地点，从而消除了用户 MPC 单元 “单点失效” 的风险。针对消费级用户的 Web 3 钱包形成无私钥 （Seedless）、无助记词的解决方案。
目前，黑客在 MPC 技术上面临着更大的挑战。为了获取用户钱包的控制权，黑客必须在多个操作平台和地点同时攻击储存 MPC 单元的各计算方。

此外，MPC 机制还允许 MPC 单元被重新初始化为三个 MPC 单元的新组合，如果先前 MPC 单元已确认损坏。三个新的 MPC 单元将重新分配给各计算方，并重新搭建安全的储存环境。这意味着即使用户丢失 MPC 单元文件，用户也可以通过重置 MPC 单元恢复钱包访问权限。

## 什么是 MPC 单元?

用户创建账户后，OpenBlock 将生成一个非托管的 MPC 钱包。与普通钱包需要用户自行保存助记词不同，OpenBlock 钱包生成的 MPC 单元通过独家加密安全算法分成三个片段：

- 第一个 MPC 单元保存在用户本地设备中。
- 第二个 MPC 单元保存在 OpenBlock 服务器中。
- 第三个 MPC 单元保存在冷储存设备中。

当用户首次注册时，服务器将自动分配第一个 MPC 单元到用户本地浏览器的一个隐藏路径中。此后用户每次登录该本地设备，该 MPC 单元将验证其作为钱包持有人的身份。

这并不是用户登录的全部流程。通过上文提及的 OpenBlock TSS 机制，钱包解锁时需要两个 MPC 单元片段共同解析。存储在 OpenBlock 服务器上的第二个 MPC 单元只有在用户通过安全检查（登录密码、支付密码、验证码等）时才会释放。用户通过持有第一个片段声明其是钱包持有人，经由服务器验证通过后，服务器释放第二个 MPC 单元，与第一个片段解析，成功后将为用户解锁钱包。

服务器将基于用户的行为提高验证级别来释放第二个 MPC 单元。登录账户需要输入正确的邮箱地址、登录密码和邮箱验证码。进行交易需要输入登录密码和支付密码。重置 MPC 单元需要输入主邮箱验证码、支付密码和安全邮箱验证码。当双重验证 (2FA) 启用时，任何修改安全设置的行为均需要通过双重验证。多种验证组合允许 OpenBlock 为风险管控创建一个安全方案矩阵，指数级地增加用户钱包被黑客攻击的难度。

当用户通过一个没有储存其账户第一个 MPC 单元的新设备或浏览器登录账户时，用户将无法访问钱包。通过所有的安全检查仅能从服务器上获得其账户的第二个 MPC 单元。用户需要通过“局域网同步”功能、从外部设备“导入 MPC 单元”或从本地文件夹上传钱包账户的 MPC 单元。

如果用户丢失了所有的已登录设备，或在没有备份的情况下重新安装了网页浏览器，那么用户将丢失其所有的 MPC 单元文件副本。现在，用户只能通过重置完整 MPC 单元来恢复访问权限。重置流程将导致原先的三个 MPC 单元的组合失效，并将完整 MPC 单元重置为三个 MPC 单元的新组合。请阅读“重置流程指南”并根据提示重置 MPC 单元。请悉知 MPC 单元重置流程需要 7 个自然日，设置缓冲期旨在防止黑客在用户不知情的情况下重置 MPC 单元或恶意诈骗。OpenBlock 强烈建议用户不要过度依赖该功能，并学习如何安全管理 MPC 单元。


# 什么是可信第三方？

v1.1

---

## 什么是可信第三方？

在社交恢复中，可信第三方是指一个用户指定的用于账户恢复的个人用户或本地设备。

可信第三方**永远无法**接触到您的资产，只负责在托管人钱包丢失时协助恢复。

## 可信第三方的类型

可信第三方通常为一个您值得信任的 **OpenBlock**** ****用户**（如，值得信赖的好友或家庭成员）

可信第三方也可以是您另一个账户

## 可信第三方的职能

1. 能够与托管方保持实际生活中的联络以迅速完成账户恢复（恢复需要双方同时在线）。
2. 在批准钱包恢复前与用户确认。
3. 始终备份用户的账户恢复单元。
4. 如果可信第三方丢失了用户的账户恢复单元，请立即通知该用户并重新发起社交恢复。


# 什么是社交恢复？

v1.4

---

## 什么是钱包恢复？

传统的 EOA 钱包，如 MetaMask，如果用户丢失私钥将无法恢复钱包。由 MPC 协议驱动的 OpenBlock 钱包，在用户失去对钱包的所有访问权限（所有的已验证设备和备份）时，一个专属的钱包恢复 MPC 单元将开始发挥其应有的功能。用户可以使用该钱包恢复 MPC 单元来发起 MPC 单元重置，从根本上重置全部三个 MPC 单元并恢复钱包访问。OpenBlock 提供两种钱包恢复模式，分别是 “OpenBlock Safe 恢复”和“社交恢复”。OpenBlock Safe 恢复是默认恢复模式，经由 OpenBlock Safe 团队管理的冷库来存储钱包恢复 MPC 单元。当用户钱包访问不存在或受到影响时，用户可以通过 OpenBlock Safe 恢复模式从冷库中取回钱包恢复 MPC 单元，以重置完整的 MPC 单元，并恢复钱包的访问权限。

## 什么是社交恢复？

社交恢复是一种去中心化的钱包恢复模式：通过一个受信任的 OpenBlock 账户，即可信第三方，来保存钱包恢复 MPC 单元。可信第三方可以是用户指定的好友或者用户自身。该可信第三方有责任保证被发起人的钱包恢复 MPC 单元的安全，并有责任在发起人需要恢复钱包时将 MPC 单元移交给发起人。因此，可信第三方需要对发起人的钱包恢复负责。**如果可信第三方不慎遗失了发起人的 MPC 恢复单元，在发起人丢失 MPC 本地单元并需要钱包恢复时，将无法恢复钱包且资产不可找回。此时请尽快重新申请一次新的社交恢复，来保证社交恢复功能可用。**

社交恢复模式可以在钱包注册时选择，也可以在后续使用中随时升级。由于初始化流程需要可信第三方批准，发起人和可信第三方需要同时在线以完成该流程，请提前通知可信第三方。

1. 可信第三方将收到电子邮件和钱包内部的推送通知，以提示完成社交恢复流程设置。
2. 可信第三方应通过已验证的设备登录，并按提示进行设置。
3. 设置完成后，发起人的钱包恢复 MPC 单元将被初始化并直接储存至可信第三方的本地设备中。可信第三方应选择备份该文件以提高额外的安全保障。
4. 当发起人进行钱包恢复时，可信第三方将被提示需要移交该钱包恢复 MPC 单元。

# 什么是私钥、公钥、助记词和钱包地址?


---

## 私钥和公钥

私钥之于加密钱包就如同现实中的钥匙与信箱的关系。私钥是一组随机生成的字符，为防止被破解，私钥长度一般设计为 256 位比特。

一个典型的私钥样式如下：

e600106a60733a1ae3cb3e3c59e362b47d2c90d76388dg47fd493h1b2efbd28c

持有私钥的钱包用户将拥有该加密钱包的绝对所有权。因此，请不要向任何人透露或分享您的私钥。

公钥是从私钥衍生出的一组字符串，就像现实信箱的邮寄地址。加密安全算法确保公钥将不可逆转为私钥。因此，用户可以安全地分享公钥，让他人向该公钥转入加密货币。当他人向该公钥转入加密货币时，任何人可以通过出示正确的私钥来收取这笔资金。

## 助记词和钱包地址

私钥和公钥通常不可见；相反，加密算法允许简化过的私钥和公钥用于共享和保存。

256 位的私钥以每组 16 位比特分成 16 组，每 16 位代表一个英文单词，即助记词。一组典型的助记词格式如下：

"Autumn saddle loyal dinner pink settle bulb sad forget absurd fever fog cat table gray tree"。

该 16 位助记词是私钥的简化形式，因此，请牢记助记词或将助记词保存在安全地址，请勿向任何人透露或分享您的助记词。

256 位的公钥同样被分解成一组较短的字符串，称为钱包公共地址。以太坊公共地址样式如下：

"0x17504553eBA2433e6952e75f4b80D23c0d519AE1"。

您可以向他人分享该钱包地址用于收取加密货币。

## 助记词的劣势及 OpenBlock 私钥安全解决方案

助记词的一大劣势是其存在“单点失效”的风险。助记词非常容易丢失、被盗和被遗忘。不仅所有拥有钱包助记词的用户均可以访问该钱包并取得钱包内全部资金，而且助记词丢失也没有任何补救措施。

无论采用哪种形式，助记词或私钥碎片来代表私钥，用户都有责任保证它们的安全。在这里阅读更多关于如何更好地保护你的 OpenBlock 账户。如果您有任何问题，请随时与我们的支持代表交谈。

为了更好地解决当前私钥和助记词模式，OpenBlock 钱包推出 MPC 安全解决方案，私钥被被 MPC 单元替代，分为多个 MPC 单元片段并发送至不同的计算方保存。这是一种更安全的私钥替代解决方案，因为所有计算方均需要签名确认钱包访问和交易发起。该安全方案同时提供 MPC 单元找回方案，安全系统将验证各计算方的身份来完成 MPC 单元重置。

无论以传统助记词、私钥碎片或是 MPC 单元替代私钥，用户均有责任保证账户信息的绝对安全。如果您遇到任何问题，请随时联系 OpenBlock 客服团队。


# 什么是粉尘 UTXO 错误？

v1.1

---

## 什么是粉尘资产？

粉尘资产 (Dust) 是指钱包中的极小额代币的价值低于发送该代币所需的交易费用，因此该粉尘资产属于无法使用的类型。粉尘资产存在于所有基于 UTXO 模型的代币类型中，如：BTC、BCH,  LTC, DOGE, RVN, DGB 等。粉尘资产是 UTXO 模型的副产物，存在破坏区块链生态系统稳定性以及造成数据存储和网络处理时间的延长致使区块链网络拥堵的可能性。（虽然粉尘资产的数额极小，但在区块链网络中需要与其他有效交易相同的数据存储量。）

## 什么是粉尘 UTXO 错误？

在钱包中显示的基于 UTXO 模型的代币余额总和，实际余额由实际可花费余额以及多个粉尘资产的个体构成。由于粉尘资产的价值小于发送其所需的交易费用的价值，且每个粉尘资产仍然是孤立和不可用的，但是粉尘资产仍然会被计入钱包总余额。未花费交易输出错误 (UTXO error) 的发生是由于多个粉尘资产的个体总价值是无效的。

例如，一个 Bitcoin 地址可能包含 0.0087 BTC。在实际使用中，该钱包包含了三笔 UTXO 资产，其价值分别为 0.0080, 0.0002 和 0.0005 BTC。假设当前每笔 UTXO 的交易费用为 0.00055 BTC，因此 0.0002 和 0.0005 BTC 的 UTXO 资产将成为粉尘资产。用户发送 0.00087 BTC 将导致粉尘未花费交易输出错误，但用户可以成功发送价值 0.00080 BTC。

该笔交易将在网络处理前被拒绝。因为处理该笔交易将减缓网络处理速度并需要超过其交易价值本身的交易费用。

## 如何解决粉尘 UTXO 错误？

1. 最好的处理方式是不要发起低于交易费用的粉尘交易。区块链网络将自动拒绝该笔交易。
2. 请将交易费用调整至略低于粉尘资产价值的较低级别。请悉知越低的交易费用将延长交易的处理时间，最长可能延长至数日。
3. 请点击“**全部**”按钮发送您余额的全部剩余部分，因为根据系统设计，该笔交易将不包含粉尘资产。


# 关于 OpenBlock KYC


---

# 什么是 OpenBlock KYC？

OpenBlock KYC 是全新的 Web3 去中心化数字身份与可信凭证，聚合各大头部 KYC Provider 的认证结果，通过 ZK 等技术实现链下认证与链上自验证，在保护用户隐私的同时，实现了个人信息的验证与证明。

在 KYC 过程中，信息的认证均在 KYC Provider 的页面进行，因此 OpenBlock 不会存储任何的 KYC 明文信息，仅可拿到 KYC 的验证结果，全面保证数据安全。

# 如何完成 OpenBlock KYC?

1. 地址签名生成 ZK ID。使用 BenFen Mainnet 的地址进行链上签名以生成 ZK ID，每个地址具有一个独立的 ZK ID，用于 KYC 结果在链上的标识。
2. 证件上传与生物识别。上传可以证明自己信息的证件，如护照、身份证、港澳通行证等，并完成人脸识别，通过 KYC Provider 的官方数据库检验后即可认证成功。

# OpenBlock KYC 的特性与核心优势是什么？

1. KYC 平台聚合器。链上聚合了各大 KYC Provider 的认证结果，无论在哪个平台完成 KYC，都可以在链上查到相关的认证记录，实现了一个地址多个 KYC 一键查询的效果。
2. 链上可用性。使用 W3C 标准下的 DID 和 VC 协议将 KYC 结果数据存储在链下，使用独特的自验证数据上链技术取代预言机，可以在保证数据真实的情况下轻松与链上的智能合约进行数据共享。用户能真正意义上获得自己身份数据的主权，并灵活地使用自己的 KYC 验证结果在协议层驱动智能合约开展业务。
3. 支持点对点身份信息验证。第三方智能合约拿到的用户信息可以是简单的 KYC 检查通过/未通过状态，也可以是更复杂的基于零知识证明的身份信息。OpenBlock KYC 在完全用户隐私的情况下，通过点对点的方式，完成向智能合约传递包括所在地范围、年龄区间、收入水平、信用等级、风险偏好等多种要素在内的用户身份证明。

# OpenBlock KYC 是怎么做的？

OpenBlock KYC 通过与 Legit ID 合作，由 Legit ID 提供 KYC 信息的验证与加密，KYC 信息经过 ZK 加密后存储在 Legit ID，并将 KYC 认证结果通过自验证数据上链技术部署在 BenFen Mainnet 的智能合约中。当 KYC 隐私信息需要验证时，通过点对点的方式，验证方与被验证方共同使用私钥对 KYC 信息进行加解密，从而完成信息的授权和验证。

# 如何保证 KYC 数据的安全性？

OpenBlock 及 Legit ID 均不存储任何用户的原始 KYC 信息，仅存储加密过的 KYC 信息，需用户凭借自己的私钥进行签名解密后才可获得全部 KYC 信息。因此，若未经用户授权签名，任何人都无法拿到 KYC 原始信息。

# 如何备份 MPC 单元？

v2.5

---

## 为什么需要备份（导入导出）MPC 单元？

在新设备上登录钱包时，需进行设备验证，比对本地 MPC 单元与服务器的解析，解锁钱包。验证方式包括设备同步和导入备份的 MPC 单元。为获取本地 MPC 单元，需从已验证设备导出这份加密的 MPC 单元。每次导出仅可备份一个本地 MPC 单元，导出新备份会使旧备份失效。为确保安全，应分别保存本地 MPC 单元。

钱包设备管理页会显示已验证设备信息，应定期检查并管理。同时，需定期检查电子邮箱警报、设备管理页以及注销不再需要登录的设备。点击此处了解更多 OpenBlock 钱包安全方案。

## 什么时候可以导入 MPC 单元？

# 如何导出私钥？

V 2.0

## 如何导出 OpenBlock 钱包账户中的私钥

尽管 MPC 单元相较于私钥拥有，安全，方便管理，可社交恢复等优势。对于依旧有私钥导出需求的用户我们还提供了“离线恢复工具”用来把  MPC 单元安全的复原为私钥。具体复原步骤如下：

1. 首先你目标导出私钥的钱包需要是一个社交恢复钱包，或者是已经转换为社交恢复模式下的钱包地址。
2. 然后在我的钱包，管理钱包页面找到“社交托管恢复 MPC 单元”按钮，跟随指引要求社交托管人提供社交托管 MPC 单元，并上传到指定位置，点击导出私钥完成私钥导出。
3. 私钥是一种非常难以管理的账户所有权证明，请妥善保管导出的私钥。可以导入传统 EOA 钱包进行使用，或者硬件钱包进行储存。

## 我们导出的哪些链的私钥:

**ECDSA**** ****私钥：**

Bitcoin      -Ethereum      -BSC         -DOGE      -Solana      -Tron

Cosmos         HECO        - Optimism        - Ronin

Osmosis        - Fantom        - Arbitrum        - Nervos

Conflux        - Polygon        - ArbitrumNova        - Cronos

ETC        - Avalanche        - ZkSync Era        - Eth Testnet

LTC        - Klaytn        - Smart BCH        - BSC Testnet

OKC        - Gnosis        - Harmony        - Sui Testnet

**暂时无法导出的 EDDSA 私钥：**

stc、sui、aptos、casper、polkadot

## 

## EdDSA 签名私钥暂时无法导入导出说明

在公钥密码学中，爱德华兹曲线数字签名算法（EdDSA）是一种数字签名方案，它使用基于扭曲爱德华兹曲线的 Schnorr 签名变体，它是由 Daniel J. Bernstein 等人在 2011 年提出的。EdDSA 签名算法通过对一组随机数和私钥进行计算，生成一个数字签名，该签名可以被验证人使用对应的公钥进行验证。

EdDSA: RFC 8032 中定义的 Edwards-Curve 签名算法

Ed25519: RFC 8032 中定义的 Ed25519 的 Edwards-Curve 签名算法

Ed448: RFC 8032 中定义的 Ed448 的 Edwards-Curve 签名算法

## EdDSA 算法签名常用于普通热钱包的私钥生成，其生成步骤如下：

1. 选择⼀个爱德华曲线，⽐如常⽤的 Ed25519 曲线。
2. 随机选择⼀个 32 字节的随机数作为种⼦，也可以从安全的随机数⽣成器中获取。
3. 通过哈希函数将种⼦转换成⼀个 32 字节的字节数组，作为私钥。
4. 通过爱德华曲线的变换公式计算公钥

而 MPC 中的 EdDSA 私钥生成通常使用的是分布式密钥生成算法，该算法可以将一个私钥分成多个部分，每个部分由不同的参与者掌握，从而实现私钥的安全生成和管理。

由于哈希类算法对 MPC 多⽅计算⽐较不友好， 所以在 MPC 钱包体系⾥，EdDSA 私钥的⽣成过程是直接使⽤了 ScalarBase 之后的数值做计算， ⼜由于哈希算法的结果不可逆性， 所以可以近似理解为 MPC 算法中是⽆法有种子私钥存在。**所以当将⼀个从 MPC 钱包体系中导出合成的 EdDSA 私钥导⼊普通热钱包的时候， 可能会存在兼容问题。 ⼤部分热钱包会将这个私钥作为随机种⼦， 做⼀次哈希。 **⽽如上述提到的 MPC 钱包私钥的生成方式，MPC 钱包中维护和可以导出的是⼀个已经 ScalarBase 和 哈希计算过的数值。由于私钥格式和计算方式的不同，**可能会出现兼容性问题。****兼容性问题可以****通过 ScalarBase 计算之后的数值作为私钥，替代通过哈希函数将种⼦转换成⼀个 32 字节的字节数组作为私钥这一步骤。**

**希望未来有更多的传统**** ****EOA**** ****钱包参与进来，制定方案标准一起解决这个兼容性问题。**

## 免私钥钱包的私钥去哪了

常见的热钱包中的私钥是一组随机生成的字符，为防止被破解，私钥长度一般设计为 256 位比特。持有私钥的钱包用户将拥有该加密钱包的绝对所有权。私钥通常不可见，通常加密算法将私钥简化为 12-24 个简单的英文单词，用于方便用户保存纪律。然而助记词的一大劣势是其存在“单点失效”的风险。助记词非常容易丢失、被盗和被遗忘。不仅所有拥有钱包助记词的用户均可以访问该钱包并取得钱包内全部资金，而且助记词丢失也没有任何补救措施。

OpenBlock 钱包使用 MPC （Multi Party Computation）技术用 MPC 单元替代私钥，将私钥分布式生成，直接在用户端和服务器端分别生成不同的私钥分片，将钱包的多方安全性最大化，而钱包的私钥从一开始就是分片的，完整的私钥从头到尾都没有出现过，解决了私钥丢失、被盗等可能性，大大降低了用户自己管理钱包的风险。

## 如何用离线恢复工具导出私钥

注意：此流程无法撤回，凡是导出私钥的 OpenBlock 账户将无法进行账户重置、恢复等操作。请咨询 OpenBlock 工作人员详细了解后执行导出私钥。

尽管 MPC 单元相较于私钥拥有，安全，方便管理，可社交恢复等优势。对于依旧有私钥导出需求的用户我们还提供了“**离线恢复工具**”用来把 mpc 单元安全的复原为私钥。具体复原步骤如下：

1. 首先你目标导出私钥的钱包需要是一个**社交恢复钱包**，或者是已经转换为社交恢复模式下的钱包地址。
2. 然后在我的钱包，管理钱包页面找到“**社交托管恢复 MPC 单元**”按钮，跟随指引要求社交托管人提供社交托管 MPC 单元，并上传到指定位置，点击导出私钥完成私钥导出。

### 步骤

1. 点击右上角 **MPC 单元图标**

![](static/LOe0bDJrEo1QLixSjVpuoIFOs3e.png)

2. 联系社交恢复人并获取**此钱包的 MPC 单元**，上传后即可导出私钥。（为了隔绝潜在网络风险，此步骤需**断开网络**进行）

![](static/Qyh6bghBVoTLPKxiD62uhIUbsTc.png)

3. 导出成功后，EcDSA 私钥将被分割成前后两段展示，用户需将两段合在一起使用。即可提取私钥妥善保管。

# 如何更好地保护您的 OpenBlock 钱包?

_v1.5_

---

OpenBlock 将安全多方计算 (MPC) 技术作为独家安全方案的核心。OpenBlock 强烈建议用户学习 MPC 钱包的工作原理，以便更好地了解潜在安全风险。用户可以遵循下面列出的行为准则来最小化加密资产或钱包的被盗风险。

## 推荐的用户行为

请注意防范假冒 OpenBlock 的钓鱼邮件或诈骗信息。OpenBlock 仅会向您发送来自 @OpenBlock.com 的邮件。在您登录钱包或输入验证信息前请多次确认登陆域名是否正确。恶意攻击者通常通过改动域名的字母顺序创建假冒的网站地址。

OpenBlock 永远不会通过邮件、电话或短信向您索要登录信息或验证码。请勿向任何人透露或分享您的账户。

请勿点击陌生邮件中自动跳转到 [https://OpenBlock.com](https://OpenBlock.com) 钱包的链接，如已打开该链接请勿轻易授权访问钱包和交易，并立即关闭该窗口，以防遭遇资金诈骗导致财产损失。

## 设备管理

请勿通过公共电脑登录您的 OpenBlock 钱包。如果不得不通过公共电脑登陆，请在退出登陆后清楚浏览器缓存以删除导入的本地设备 MPC 单元。同时删除浏览记录将最小化钱包向公众暴露的风险。

OpenBlock 为提升用户访问便捷性，提供本地浏览器保持用户登录状态 30 天的功能。这一功能在笔记本电脑、移动平板等设备丢失或被盗的情况将导致账户安全性降低。请注意设备环境，并尝试在每次钱包使用后退出登录。

由于 MPC 安全方案的实施，用户可以从多个设备和平台登陆钱包。OpenBlock 将为用户提供最佳的多登录设备管理工具。但用户仍有义务尽量减少登录设备的数量，因为越少的登陆设备意味着潜在攻击的可能性越低。

团队或项目方请使用 OpenBlock 企业钱包模式。该功能将指数级提高团队钱包的安全性。

## 身份验证管理

邮件是 OpenBlock 最主要的验证方案。请确保您的邮箱账户安全。OpenBlock 建议您使用一个不常用或指定的邮箱用于 OpenBlock 账户注册。

登录密码和支付密码是 OpenBlock 钱包的第二级防护系统。两种密码的结构是不同的，登录密码是复杂的数字字母和符号的组合，而支付密码是六位数字。在设定两种密码时，请保持两种密码根本性的不同。此外，请保持两种密码与您日常邮箱密码和移动设备密码的不同。

OpenBlock 支持多种双重身份验证方案 (2FA) 保护账户安全。请在完成注册后绑定并启用双重身份验证功能 (2FA)。在黑客突破前两级防护系统后，双重身份验证功能将成为钱包的第三级防护系统保护账户安全。

安全邮箱是验证用户身份的最后一道安全方案。当用户重置 MPC 单元时需要使用安全邮箱。出于账户安全和用户财产安全考虑，请将该邮箱安全风险降到最低，并为丢失所有登录设备和全部 MPC 单元文件的最糟情况做充足准备。没有安全邮箱，您将无法恢复 MPC 单元。

OpenBlock 最后的建议是请永远不要公开或对外分享您的登录设备、身份验证和资产等信息。如果您有任何疑问，请随时联系 OpenBlock 团队。

# 如何绑定谷歌验证

v2.0

---

谷歌身份验证器（GA）是一个免费的安全应用程序，保护您的账户免受账号密码被盗风险。**双重****验证功能(2FA)会在您登陆 OpenBlock 账户时要求进行第二步验证，从而为您的账号提供更强的安全保障。**双重验证功能使黑客更难使用您的身份信息入侵您的钱包盗取您的资产。即使您的账户密码泄露，第二步的登陆过程将阻止他人登陆钱包。

GA 每三十秒随机生成六位验证码。用户输入有效验证码确定身份信息，实现额外一层安全保障。该应用程序可以在无网络环境下使用。

绑定谷歌双重验证(2FA)是非强制性的，OpenBlock 强烈推荐资产净值 $10,000 以上的账户启用谷歌双重验证(2FA)更好的保护您的加密资产安全。

# 如何重置 MPC 单元?

v2.4

---

## 为什么需要重置 MPC 单元？

OpenBlock 钱包安全的本质是用户需要在本地设备中完成 MPC 单元验证 。只有已验证设备才能访问钱包并发起交易。OpenBlock 目前为用户提供两种验证新设备的方法：设备同步和导入 MPC 单元。用户应知晓如何科学管理已验证设备，并保证钱包账户长期的安全性。

如果用户不慎遗失已验证设备或 MPC 单元文件，上述两种验证方法将不再可用。因为这相当于丢失了传统 Web 3.0 钱包的助记词或私钥。相较于传统钱包，OpenBlock 的 MPC 安全方案专为消除该类单点故障而设计。

MPC 安全协议和 2-3 TSS 架构允许用户重置完整的 MPC 单元。遗失的本地 MPC 单元将被重置后的新的本地 MPC 单元替换，并用于恢复钱包的访问。重置功能也适用于认为本地 MPC 单元已受损的钱包用户。在整个重置流程中，用户的钱包内资产、钱包地址以及账户所有权归属仍保持不变。

由于重置 MPC 单元是账户恢复的最终解决方案，且整个重置流程是专为网络钓鱼、诈骗和黑客而精心设计，为保护您的账户安全，完成整个重置流程需要 2 天的缓冲期。该方案将避免黑客以钓鱼手段获取用户的身份信息登录钱包并重置 MPC 单元进一步造成用户资产损失。在 2 天缓冲期内，作为安全提示，OpenBlock 将每日推送邮件通知告知用户目前正在进行重置流程。如果是非用户本人发起的重置流程，用户可以立即取消重置。

以下规则适用于 OpenBlock 额外的安全层：

1. 在 2 天缓冲期内，所有交易行为将被禁止。
2. 重置流程可以在任意已验证设备中发起，但是整个重置流程仅能在发起重置的设备上完成。
3. 重置完成后，所有已验证设备和备份的本地 MPC 单元将失效。

即使用户恢复了旧设备或已备份的本地 MPC 单元，也无法撤销已完成的重置。请使用重置后的新的 MPC 单元，并重新验证您信任的设备。

## 请按照以下步骤重置您的 MPC 单元（网页端）：

### 第一部分

1. 登录 OpenBlock 钱包，点击右上方“**MPC 单元图标**”。
2. 点击“**重置 MPC 单元**”。

# 如何在通过 MD5 确保安全重置安全

## 使用场景

对于安全性要求较高的用户，可以在打开 MPC 单元前校验 MD5 值，以验证 MPC 单元文件完整性。

## 操作步骤

1. 获取 MD5 值：您将在重置 MPC 单元的邮件中收到 MD5 值，内容示例：
2. 验证 MD5 值：将附件中的 MPC 单元文件上传至 MD5File 网站（[https://md5file.com/calculator](https://md5file.com/calculator)），您将会看到解析出来的 MD5 值，将邮件中的 MD5 值与之核对，核对无误后，再将 MPC 单元文件上传至 OpenBlock 官网，等待解析完成即可。

# 账户余额显示异常如何处理?

v1.2

---

首先，请在转账网络的区块浏览器查看钱包地址和交易哈希 (TxID)（如以太坊主网的 Etherscan、Arbitrum 网络上的 Arbiscan）。如果区块探索器显示的是与钱包一致的异常余额，请按以下步骤继续执行操作：

## 如果您在最后一次转账后余额显示异常：

### **网络异常**

1. 尝试切换网络。如果您的网络较差或不稳定，OpenBlock 将无法与服务器连接以加载正确的余额。
2. 尝试刷新钱包页面或重新打开您的浏览器。
3. 检查您的网络环境，是否连接在陌生网络或网络端口被封的 VPN 上。

## 如果您的余额仍然显示异常，请检查下方列出的原因：

- **错误的转账地址**：请检查您最近的交易信息，并确认您是否将资金发送至正确的钱包地址。
- **错误的区块链网络**：请检查您提币的区块链与您在 OpenBlock 钱包充值的区块链是否一致。例如，当您通过以太坊网络发送 ERC20 格式的 USDT，您需要将您的 OpenBlock 钱包切换至以太坊网络来查看 USDT 余额。当钱包切换至其它区块链网络时，例如 BNB、HECO、ARB 等链，您 ERC20 格式的 USDT 余额将不再显示。
- **交易正在进行中**：由于链上交易量较大导致网络拥堵以及您支付的较低 Gas 费可能导致资金到账延迟。导致资金延迟到账的原因包括：提币平台风控、网络拥堵、低 Gas 费导致交易排队时间长。
- **不常见的高额**** ****Gas**** ****费用**：在极端情况下，Gas 费存在价格极高的可能性。当您在钱包确认交易但未注意到极高的 Gas 费价格，您可能会在“不知情”的情况下支付了高额 Gas 费用导致您的财产损失。

安全提示：此现象常见于以太坊网络。

## 如果您近期没有任何交易且余额显示异常：

**错误的钱包账户**：如果您同时拥有多个 OpenBlock 账户，请检查您是否登录了正确的钱包账户。

**代币预授权**：链上应用 (DApps)、NFT 平台、领取空投奖励及其它 Web 3.0 网站可能会要求您授权一定额度的代币交易，其有权在限定时间转移您授权的指定额度的代币。在 OpenBlock 钱包币种页面下您可以查看您的代币授权历史记录。

安全提示：如果代币授权历史记录中显示了您不知情的授权方或授权金额，您很可能已经遭遇加密诈骗。攻击者制作的假冒网站或链接诱使您在钱包中确认授权。

**检查交易记录**：请检查交易记录中是否有除您以外的人对您的代币发起转账。黑客很可能入侵了您的钱包，在您不知情的情况下盗取您的资金。

如果您已经检查上述所有场景但仍坚信账户余额异常，请立刻联系 OpenBlock 客服团队 support@openblock.com。请在邮件中详细列出所有必需的信息（例如：交易确认页截图、交易哈希等)。OpenBlock 将根据您提供的信息尽快完成调查并回复您的请求。
