# Json Web Token(JWT)
Source: https://docs.chainbase.com/api-reference/jtw



## What is a JWT?

JSON Web Tokens (JWTs), also known as JOTs, were created to establish a standard and secure method for two parties to communicate. They offer the advantage of stateless session management, eliminating the need for communication between a backend server and an authorization server.

JWTs can be transmitted via an HTTP header, URL, or POST parameter, and their compact size contributes to their efficiency. A JWT comprises three parts: a **Header**, **Payload**, and **Signature**, each separated by a period and derived from a JSON object that is encoded into a text string using BASE64. Further information on this standard is available in [RFC-7519](https://tools.ietf.org/html/rfc7519).

## How to use JWT in Chainbase?

Chainbase now provides users with the option to safeguard their blockchain nodes using the JWT authentication method. This feature can be utilized either as a stand-alone security measure or in conjunction with other protective methods offered by Chainbase, including IP whitelisting and domain whitelisting. It should be noted that if multiple authentication services are activated on a project, each method must successfully pass its security check, or the user request will result in an error.

### Generate your RSA-256 keys

Chainbase supports JWTs created from key pairs using the **RS256** algorithm.

Generate your own **RSA-256** public and private key with 2048 length. Below is the example using OpenSSL.

```bash
# generate rsa key
openssl genrsa -out jwtRSA256-private.pem 2048
openssl rsa -in jwtRSA256-private.pem -pubout -outform PEM -out jwtRSA256-public.pem
```

### Add public key to a Chainbase Project

Step 1: Login -> Dashboard -> Choose a project -> Security (tab)

Step 2: Click "Add" button and Input the public key generated in the previous step.

Step 3: You will obtain the public key ID after clicking "Create" button.

### Enable JWT feature

After enabling the JWT feature, it is mandatory to include the JWT in the header of all subsequent requests.

  <img src="https://files.readme.io/d0ac1f2-image.png" />
</Frame>

### Generate the JWT

To generate a JWT, the following components are required: **Header**, **Payload**, and **Signature**.

An example of how to generate a JWT using [https://jwt.io/](https://jwt.io/) is provided below.

<Frame caption="Encode and verify JWT using the debugger">
  <img src="https://files.readme.io/bad111d-image.png" />
</Frame>

Step 1: Choose **RS256** algorithm

Step 2: Paste the following JSON to the JWT tool to encode the **Header** component.

```json
{
  "alg": "RS256",
  "typ": "JWT",
  "kid": "e7af4467-00f1-480e-97d7-6490d7f749b9"
}
```

Here are the meanings of the fields:

| Field | Description                      | Example |
| :---- | :------------------------------- | :------ |
| alg   | The signing algorithm being used | RS256   |
| typ   | The type of the token            | JWT     |
| kid   | The key id copied from Chainbase | XXX     |

Step 3: Paste the following JSON to the JWT tool to encode the **Payload** component.

```json
{
  "aud": "chainbase.com",
  "exp": 1690523501
}
```

Here are the meanings of the fields:

| Field | Description                             | Example       |
| :---- | :-------------------------------------- | :------------ |
| aud   | The audience of this JWT                | chainbase.com |
| exp   | The expiry time. Unix timestamp format. | 1690523501    |

Step 4: Input your private key to generate the **Signature** component.

Congrats! Now you get the encoded JWT. You can verify your token by providing your public key to the JWT debugger.

### Send requests with JWT

After generating the JWT, you would need to add the JWT as a part of your request header `-H "Authorization: Bearer` entry.

```bash
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer <YOUR-JWT>" \
--data '{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": []}' \
"https://ethereum-mainnet.s.chainbase.online/v1/<YOUR-API-KEY>"
```

In the event that the JWT feature has been activated but requests are sent without a JWT or with an invalid JWT, an HTTP **401** error status code will be returned along with the following response.

## FAQ

> Q: Which APIs are JWT supported on?
>
> A: JWT is supported on all Chainbase API services.

> Q: How do I discard a JWT before it expires?
>
> A: If your JWT might have been exposed and you want to prevent it from being used, you can remove the public key from the security tab.

> Q: Can I add multiple JWTs to a project?
>
> A: Yes. If multiple JWTs are active, the request should only match one of the available keys to succeed. Chainbase now supports up to 3 keys.

> Q: Which cipher does Chanbase support?
>
> A: RSA 256 (RS256) is supported at this time.

> Q: What expiration date should I choose?
>
> A: You can set any expiration date in the future you'd like. Generally, the shorter the expiration time, the more secure your JWT is.

# Data Cloud SQL Query (Classic)
Source: https://docs.chainbase.com/api-reference/sql-api/data-cloud-sql-query

post /dw/query

## Example

Query the hashes of the last 3,000 blocks in Ethereum and the number of transactions in each block:

```bash
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
     -H 'X-API-KEY: YOUR-API-KEY ' \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
  "query": "select number, transactions_count from ethereum.blocks order by number desc limit 3000;"
}'
```

If there are more than 1000 rows, you need to paginate through the`task_id` and `page` to get all the results:

```bash
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
     -H 'X-API-KEY: YOUR-API-KEY ' \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
       "task_id": "xxxxxxxxxxxxxxxxxxxxx",
       "page": 2
}'
```

<Note>
  🚧 Note

  1. When `quey_id` is passed in, the content of query will be ignored
  2. The executed request generates a `task_id`, which is valid for 1 hour
  3. A maximum of 100,000 pieces of data are allowed to be obtained from the request, and 1,000 results are paginated per page

This cost efficiency makes it more affordable for users and developers to interact with decentralized applications, fostering greater adoption and usage.

3. **EVM Compatibility**: Arbitrum is fully compatible with the Ethereum Virtual Machine (EVM), enabling developers to deploy their existing Ethereum-based smart contracts and DApps on Arbitrum with minimal modifications. This compatibility ensures a seamless transition for developers and allows them to leverage Ethereum’s extensive ecosystem of tools and libraries.


# Raw
Source: https://docs.chainbase.com/catalog/Arbitrum/Raw



## 1.arbitrum.blocks

### Table Description

The arbitrum.blocks table stores crucial data about the Ethereum blockchain's block structure. Each block in the Ethereum blockchain contains a unique set of data that ensures the integrity and chronological order of transactions. Blocks are the building blocks of the Ethereum blockchain, and they contain several key components:

1. Block Header: This includes metadata such as the block number, timestamp, parent block hash, and nonce. The header is essential for maintaining the blockchain's integrity and linking blocks together in a chain.

2. Transactions: Each block includes a list of transactions that have been validated and added to the blockchain. These transactions consist of various operations, such as transfers of Ether, execution of smart contracts, and other state changes.

3. Uncle Blocks (Ommer Blocks): These are blocks that were mined but not included in the main chain. They are referenced in the block to improve the chain's security and reward miners for their efforts.

4. State Root: This is a cryptographic hash representing the state of the entire Ethereum network at the time the block was mined. It includes account balances, storage, and other state data.

5. Receipts Root: This is a hash of the receipts of all transactions included in the block. Receipts contain information about the execution of transactions, such as gas used and logs generated.

The arbitrum.blocks table provides a detailed and organized view of the blockchain's structure, allowing for efficient retrieval and analysis of blockchain data. This information is crucial for developers, researchers, and analysts working with the Ethereum blockchain, as it enables them to understand the state and evolution of the network.

## 1.arbitrum.contracts

### Table Description

The arbitrum.contracts table contains essential data about smart contracts deployed on the Ethereum blockchain. Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They are a fundamental aspect of Ethereum, enabling decentralized applications (DApps) and automating complex transactions without intermediaries. The arbitrum.contracts table includes several key components:

1. Contract Address: This is a unique identifier for each smart contract deployed on the Ethereum network. It is derived from the creator's address and the transaction nonce.

2. Creator Address: This is the Ethereum address of the account that deployed the smart contract. It provides traceability and accountability for the origin of the contract.

3. Creation Transaction: This includes the transaction hash of the deployment transaction, linking the contract to the specific transaction that created it.

4. Bytecode: This is the compiled code of the smart contract that gets executed on the Ethereum Virtual Machine (EVM). It includes the contract's logic and functions.

5. ABI (Application Binary Interface): The ABI defines the contract's interface, including its functions, inputs, and outputs. It is crucial for interacting with the contract programmatically.

6. Source Code (optional): Some contracts include the original source code, providing transparency and enabling verification of the compiled bytecode.

7. Block Number: This indicates the block in which the smart contract was deployed, providing a chronological context for the contract's creation.

8. Timestamp: The exact time when the smart contract was deployed, allowing for time-based analysis and tracking.

Ethereum blockchain is a decentralized platform capable of executing smart contracts and decentralized applications (DApps). It was introduced by Vitalik Buterin in 2015 and is more general and flexible compared to Bitcoin's blockchain. The core of Ethereum is its virtual machine, the Ethereum Virtual Machine (EVM), which can execute Turing-complete scripts, allowing developers to create and deploy smart contracts.

### The Major Features of the Ethereum Blockchain

1. **Smart Contracts**: Smart contracts are self-executing contracts with predefined rules and conditions, running on the Ethereum blockchain. Once the conditions are met, the contract's execution is irreversible, ensuring transparency and trust. Smart contracts enable complex decentralized applications, such as decentralized finance (DeFi) platforms and non-fungible token (NFT) marketplaces. The automation and immutability of these contracts are core advantages of blockchain applications.

2. **Decentralized Applications (DApps)**: Ethereum supports the development and deployment of decentralized applications, which run on the blockchain without being controlled by a single entity. This makes applications more transparent and secure, while also reducing the risk of single points of failure due to centralized control. Developers can leverage Ethereum's tools and frameworks to create innovative decentralized solutions. The widespread application of DApps spans various sectors, including financial services, supply chain management, and identity verification, showcasing the versatility and innovative potential of the Ethereum platform.

# BNB Smart Chain Testnet
Source: https://docs.chainbase.com/catalog/OtherEvm/BNB_Smart_Chain_Testnet



\-- Layer1 blockchain

In early 2019, Binance launched Binance Chain. By 2020, the community utilized source code from the Ethereum network and launched a modified EVM-compatible blockchain called Binance Smart Chain. In February 2022, both the Binance Chain (rebranded as BNB Beacon Chain) and the Binance Smart Chain (rebranded as BNB Smart Chain) evolved into a unified, modular system referred to as BNB Chain. This dedicated layer1 blockchain is dedicated to building the infrastructure powering the world’s parallel virtual ecosystem. When the two blockchains merged, the Beacon Chain became the dedicated layer used for Governance (staking & voting), and the BNB Smart Chain became the dedicated layer for EVM consensus and execution.

# Ethereum Classic
Source: https://docs.chainbase.com/catalog/OtherEvm/Ethereum_Classic



\-- The first blockchain with smart contract functionality

Ethereum is the first decentralized, open-source blockchain with smart contract functionality. It was initially described in a white paper by Vitalik Buterin in late 2013 and launched in 2015. This network serves as the foundation for an ecosystem of interoperable, decentralized applications (dApps) powered by token economies and automated smart contracts. Assets and applications designed on Ethereum are built with self-executing smart contracts that eliminate the need for a central authority or intermediary. 
The network is powered by its native cryptocurrency ether (ETH), which is used to pay transaction fees. Ethereum has the characteristics of being open-source, programmable, private, and censorship-resistant, forming the backbone of a decentralized internet.

# ☆ Overview
Source: https://docs.chainbase.com/catalog/zkSync/Overview



zkSync is a Layer 2 scaling solution for Ethereum, designed to provide high throughput and low transaction costs while maintaining the security and decentralization of the Ethereum network. Developed by Matter Labs, zkSync leverages zk-rollup technology to offer fast and cost-effective transactions, making it a powerful platform for decentralized applications (DApps).

### The Major Features of the zkSync Blockchain

1. Scalability: zkSync significantly enhances Ethereum's scalability by bundling multiple transactions into a single batch, which is then processed off-chain before being committed to the Ethereum main chain. This zk-rollup technique allows zkSync to handle thousands of transactions per second, reducing congestion and improving overall network performance.

2. Low Fees: By processing transactions off-chain and only recording the final state on the Ethereum main chain, zkSync dramatically reduces transaction fees. This cost efficiency makes blockchain interactions more affordable for users and developers, promoting greater adoption and usage of decentralized applications.

3. EVM Compatibility: zkSync is fully compatible with the Ethereum Virtual Machine (EVM), enabling developers to deploy their existing Ethereum-based smart contracts and DApps on zkSync with minimal modifications. This compatibility ensures a seamless transition for developers and allows them to leverage Ethereum’s extensive ecosystem of tools and libraries.

* **Security**: Tolerates any type of failure, including malicious attacks.
* **Consistency**: All normally operating machines can see the same transaction logs and calculate the same state.

## **Features of CometBFT**

* **Byzantine fault tolerance**: CometBFT can tolerate less than one-third of machine failures, which can be in any form, including malicious attacks.
* **Universal Application Interface**: Through the Application Block Chain Interface (ABCI), developers can use any programming language and development environment to build their own application logic.
* **High performance and ease of use**: CometBFT is simple in design, high in performance, and suitable for various distributed applications.
* **Modular design**: Separates the consensus engine from application state management, providing a flexible development environment.

## **Why Choose CometBFT as the Consensus Engine**

In the distributed network of Chainbase Data Network, all execution layer nodes need to reach a consensus on the status of large-scale data processing. The efficiency and resilience of consensus are key factors, so CometBFT is an ideal choice. It ensures that the system can efficiently and robustly reach consensus when processing large amounts of data, providing strong support.

## **How to Integrate CVM Consensus**

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/consensus-layer-1.png)

### CVM Consensus

1. **Block Proposal:** Validators take turns proposing new blocks. The proposing validator requests the latest block from CVM through the Engine API.
2. **Block Construction:** The execution layer CVM obtains the source data to be processed from the Data Accessibility Layer, runs the logic of the Manuscript data processing submitted to the network, generates the result of the Dataset record and index proof, and builds a new CVM block.
3. **Block Inclusion:** The proposed CVM block is packaged as a CometBFT transaction and added to the consensus layer block, ready for network validation.
4. **Finalizing Blocks:** If the proposed consensus layer block obtains the approval of two-thirds of the validator set, the block will be finally determined and added to the Chainbase Data Network chain. These final blocks include the index proof and state after CVM processes the data, and the final consensus block represents that this processed data can be used externally.

## Glossary

* Data Providers: Provide On-Chain or Off-Chain data
* Data Consumers: Consumers like LLM / Developers / Data Engineer and so on.
* SCP: Storage-Based Consensus Paradigm. This is how the dataset is being proved.
* CDC(Changelog): Change Data Capture. Data stored permanently in Arweave, like changelog which generated by CDC.
* Dataset: Data set which is stored in any database or file system. It can be accessed directly by the data consumer through API / SQL / Sync.
* Data Manifest: Data manifest is a metadata file that contains the information about the dataset.

## Data Flow

1. Data Providers collect On-Chain & Off-Chain data, then push the data with Zero-Knownledge Proof to CVM.
2. The CVM verifies the raw data provided by the Data Provider and writes the data permanently and immutably into Arweave in the form of a Changelog(CDC), while updating the data index in the Manifest.
3. The Manuscript consumes the raw data in a streaming manner using the CDC approach to extract and process high-value data.
4. The processed data can be directly stored in a database or local files, and the CVM provides direct data access services via SQL/API/Sync

# Solved Problems

## Distributed Data Lake

The raw data is stored immutably and in a decentralized manner on Arweave. The data is shared according to specific rules and uploaded to Arweave after sharding. The data shards are maintained through a Manifest and the query index is provided by the Scheduler.

The structure of the Manifest is as follows:

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/da-2.png)

The data within the shards is stored in the form of a Changelog. The contents of the Changelog are as follows:

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/da-3.png)

Storing data in the Changelog format has the following advantages:

1. Elegantly solves the Reorg issue in blockchain data.
2. Data is written in an Append Only manner, eliminating the need to handle conflicts, allowing for optimal data freshness.
3. The downstream CVM can continuously read upstream data in a streaming manner then process it. While benefiting from the compounding effect of upstream data, the downstream data also maintains good data freshness.

## Proof of Raw Data

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/da-4.png)

Chainbase Network uses Zero-Knowledge Proof(ZKP) technology to prove the source and integrity of the data. Any network user can verify the source and validity of the data based on the ZKP.

The network’s raw data comes from decentralized Data Providers. These Data Providers obtain data from different Web3 RPC service nodes and use consensus algorithms to determine the final data results, thereby preventing any single data provider from supplying incorrect or malicious data.

Chainbase Network also establishes an SLA(Service Level Agreement) that Data Providers must adhere to regarding data quality and service standards. If Data Providers violate the corresponding SLA, they may face penalties.

## Proof of Indexed Data

Indexed Data is verified using SCP(Storaged-Based Consensus Paradigm).

The basic principles are as follows:

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/da-5.png)

All verified Raw Data is immutably and persistently stored on Arweave. Manuscript is a data processing script written in programming languages such as Python, Javascript, Rust, and SQL, which are consensus already taken in the physical world. These data processing scripts will remain open-source, allowing any Validator to verify the generated Indexed Data based on Raw Data and Manuscript, thus achieving consensus on Indexed Data in a simple and effective manner

# Summary

In summary, Chainbase Network stands out by leveraging advanced technologies like Zero-Knowledge Proof(ZKP) and a Storage-Based Consensus Paradigm(SCP) to ensure data integrity and reliability. With decentralized and immutable storage on Arweave, and Manuscript for data processing, Chainbase Network offers robust data verification, seamless data services, and unparalleled data freshness.

This decentralized data lakehouse establishes Chainbase Network as a leader in secure and efficient data management.

# Chainbase Network AVS Design
Source: https://docs.chainbase.com/core-concepts/avs-design



## **Overview**

EigenLayer's AVS is a cornerstone of its high-performance execution layer. Details to be specified [here](/core-concepts/data-processing-based-on-avs).

## **Integration with EigenLayer Core (AVS Directory)**

To integrate with EigenLayer Core, Chainbase Network implements an instance of ECDSAServiceManagerBase or ServiceManagerBase (BLS). This integration allows operators to register by sending transactions to the AvsServiceManager, completing the registration process
![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/avs-design-01.png)

## **On-Chain Verification Challenges**

Chainbase Network requires a stable and efficient group of operators to form a decentralized and trusted data processing network. The Coordinator component needs a mechanism to measure the operational quality of these operators, ensuring they meet the network's standards. This is achieved through an on-chain consensus game involving slashing for non-compliance.

The Coordinator periodically generates a challenge task, which involves calculating the block hash of a specific block within the blockchain data integrated into Chainbase Network. This task has a clear answer and expected outcome. The challenge is sent to operators' manuscript-node nodes, where they execute the task and return the signed result along with the recorded task execution time. This information is used to evaluate the operators' efficiency, and the results are verified on the AVS chain.
![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/avs-design-02.png)

## **Implementation Details**

**Coordinator:**

1. Listens to the on-chain contract `ChainbaseServiceManager` events.
2. Sends tasks to `Manuscript Node` via an RPC interface.
3. Receives task responses from `Manuscript Node` via the RPC interface.
4. Aggregates responses from multiple `Manuscript Nodes` and submits the results to the on-chain contract `ChainbaseServiceManager`.

**Manuscript Node:**

1. Registers the operator by calling `RegisteryCoordinator`.
2. Receives tasks from the Coordinator via the RPC interface.
3. Executes tasks, signs the task response.
4. Sends the signed task response back to the Coordinator.

**Contracts:**

1. The `ChainbaseServiceManager` contract includes functions for `createNewTask` and `respondToTask`, facilitating the creation of tasks and the submission of task responses for verification.


# Data Processing Based on AVS
Source: https://docs.chainbase.com/core-concepts/data-processing-based-on-avs



## **Overview**

Chainbase Network is an hyperdata network powered by a [dual-chain](/core-concepts/dual-chain) architecture using Cosmos and EigenLayer, enabling trustworthy and transparent on-chain data processing. Through the [Manuscript protocol](/core-concepts/manuscript) on the Chainbase Virtual Machine (CVM), the network ensures seamless data interoperability. By integrating [EigenLayer’s](https://www.eigenlayer.xyz/) staking mechanism, Chainbase leverages Ethereum's economic security to build a high-performance AVS for its [Execution Layer](/core-concepts/architecture/execution_layer). This ensures large-scale data processing while maintaining security, decentralization, and scalability, supporting the growing demands of blockchain applications.

## Execution layer node based on AVS

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/data-processing-based-on-avs.png)

The execution layer nodes of Chainbase Network are built on EigenLayer, providing users with a node network for on-chain data processing. Developers can submit Manuscript data processing programs and request the final result dataset. EigenLayer operators with computational resources can restake and register as execution layer nodes of Chainbase Network, providing the required computing resources. As Chainbase Network integrates data query fees, restakers will generate income from it.

As more and more Manuscripts run on Chainbase Network, more high-quality computing resources are needed. To achieve elastic scaling of resources while maintaining high throughput, on-chain computing tasks need to be routed to the best provider according to the running preferences of Manuscript. Key factors include node geographic location (latency), computing hardware, and network environment. EigenLayer will support Chainbase Network through diversified operators and routing strategies to meet these needs.

### **Summary**

Chainbase Network is a full-chain data network supported by the dual-chain architecture of Cosmos and EigenLayer, aiming to provide a trustworthy and transparent data processing environment. To achieve interoperability, the Manuscript protocol was developed and runs on the Chainbase Virtual Machine (CVM), designed for large-scale data processing.

By combining EigenLayer's staking mechanism, Chainbase Network enhances economic and safety guarantees and builds a high-performance execution layer. EigenLayer operators can register as nodes of Chainbase Network, provide computing resources, and profit through integrated data query fees.

With the increase of Manuscript operations, the system needs more high-quality computing resources, and EigenLayer provides diversified operators and routing strategies to support this demand.

# Dual-Staking
Source: https://docs.chainbase.com/core-concepts/dual-staking



# Why dual staking?

* Early PoS (Proof of Stake) networks can face a "death spiral" problem. If the token's value decreases, it weakens the network's security, leading to a decline in Total Value Locked (TVL), which further depresses the token price, thus creating a death spiral.

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/dual-staking-1.png)
capture:[https://www.blog.eigenlayer.xyz](https://www.blog.eigenlayer.xyz)

# How it works

Protect the same PoS network using two tokens, one of which can be a low-volatility, deep-liquidity, more accessible external network token such as Ethereum (ETH). Also use network native tokens to capture network value

# Different method

**Modular Dual Staking**: Local operators and ETH-backed operators are required to reach a quorum respectively.

**Native Dual Staking**: Similar to mesh security, two sets of operators are treated as one, each operator's stake is converted into unified units based on an external oracle, and the user then validates the response based on the combined quorum.

**Veto Dual Staking**: The local operator is first individually quorate and the ETH-backed operator acts as a safeguard to check the behavior of the local operator. If the local operator makes a mistake, the ETH-supported operator has the right to veto a valid response sent by them.

### Impl architecture

![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/dual-staking-2.png)

1. support LST && native token stake

for supported LST please check:[https://app.eigenlayer.xyz/restake](https://app.eigenlayer.xyz/restake)

\$C is our native token, for more detail TBD

2. how to manage stake token

* for LST part, staker first stake to operator then operator register  to our AVS. offline relayer watch && sync avs’s operator stake & delegations(eg.`sync(CainbaseAVS.Operator[] calldata operators`)) info with cosmos part(maybe call xxx chain ?)
* For the \$C part, stakers interact with erc20-stake contract to emit a `Stake(bytes operator_pubkey, uint256 amount)` event. The relayer then watches for this event and syncs the information with the Cosmos part.
* We choose the Native Dual Staking model where an oracle ensures fair price conversion of both `$LST` and `$C` into `$C-Stake` units.

| `TIMESTAMP_LTZ` |                                     |

## Operators

### SELECT & WHERE clause

The general syntax of the `SELECT` statement is:

```sql
select select_list from table_expression [where boolean_expression]
```

The `table_expression` refers to any data set in Chainbase Network. It could be an existing table, or VALUES clause, the joined results of multiple existing tables, or a subquery. The following would read all rows from `blocks`.

```sql
select * from blocks;
```

The `select_list` specification `*` means the query will resolve all columns.

Instead, a `select_list` can specify a subset of available columns or make calculations using said columns. For example, if `token_transfers` has columns name `token_id`, `token_value` and `token_decimal` you could write the following query:

```sql
select token_id, token_value / token_decimal from token_transfers;
```

Rows can be filtered based on a `WHERE` clause:

```sql
select * from ethereum.blocks where block_number = 19938860;
```

### ORDER BY clause

The `ORDER BY` clause causes the result rows to be sorted according to the specified expression(s). If two rows are equal according to the leftmost expression, they are compared according to the next expression and so on. If they are equal according to all specified expressions, they are returned in an implementation-dependent order.

```sql
select * from blocks order by block_timestamp, block_number;
```

### LIMIT clause

`LIMIT` clause constrains the number of rows returned by the `SELECT` statement. In general, this clause is used in conjunction with `ORDER BY` to ensure that the results are deterministic.

The following example selects the latest 10 blocks on blocks table.

```sql
select * from blocks order by block_timestamp limit 10;
```

### SELECT DISTINCT

If `SELECT DISTINCT` is specified, all duplicate rows are removed from the result set (one row is kept from each group of duplicates).

```sql
select distinct contract_address from token_transfer;
```

### Group Aggregation

An aggregate function computes a single result from multiple input rows. For example, there are aggregates to compute the `COUNT`, `SUM`, `AVG(average)`, `MAX(maximum)` and `MIN(minimum)` over a set of rows.

```sql
select count(1) from blocks
```

The standard `GROUP BY` clause is also supported for aggregating data.

```sql
select count(*) from token_transfer group by contract_address
```

### Joins

INNER Equi-JOIN:

```sql
select *
	, token_metas.token_decimal
from token_transfer
inner join token_metas
on token_transfer.contract_address = token_metas.contract_address
```

OUTER Equi-JOIN:

```sql
select *
	, token_metas.token_decimal
from token_transfer
left join token_metas
on token_transfer.contract_address = token_metas.contract_address
```

### INSERT Statement

`INSERT` statements are used to add rows to a dataset.

Syntax:

```sql
insert into table_name select_statement
```

Examples:

```sql
create table latest_10_blocks (
	  block_number bigint NOT NULL COMMENT 'Block number uniquely identifying the block',
    hash varchar(66) NOT NULL COMMENT 'Hash value representing the unique identity of the block(with bloom filter)',

# What is Manuscript?

Manuscript is a revolutionary blockchain data streaming framework. With Manuscript, you can seamlessly integrate on-chain and off-chain data into target data storage for unrestricted querying and analysis.

# Vision of Manuscript

![manuscript\_01.png](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/manuscript_01.png)

The vision of Manuscript is to realize "data trade" within the Chainbase network, establishing a Chainbase ecosystem component that allows users to access any data through any means, across any service, using any language. This grand vision can be broken down into the following key aspects:

* Any language: We hope users can use scripts in any mainstream programming language to customize data, including but not limited to: Golang, Rust, Python, Node.js, Java, C/C++, Zig, WebAssembly (WASM)
* Any method: Different users are familiar with different forms of data access, we hope users can access data through various means, including but not limited to: SQL, DataFrames, HTTPS, gRPC, FTP, WebDAV, FUSE
* Any data: Users should be able to access data in any format, such as: JSON, CSV, ORC, XML, XLSX, BLOB
* Across any service: Users' expected data storage services also vary, we hope users can access, transfer, and control data in any service, such as: RPC, S3, IPFS, Azblob, HDFS, Google Drive, BigQuery, WebDAV, MySQL, PostgreSQL

In the Chainbase ecosystem, on-chain data can be tagged, categorized, and processed, transforming complex data into easily understandable and usable forms. Artificial intelligence algorithms can automatically analyze massive blockchain data, discovering hidden patterns, trends, and anomalies, helping users gain insights from the data. Manuscript provides rich tools and resources for this process, making data processing more efficient and transparent. Through these technical means, Manuscript not only makes access to on-chain data more free and flexible but also greatly enhances the value of data, allowing more people to easily use and apply this on-chain data.

This mechanism not only incentivizes the production of high-quality data but also promotes the positive development of the entire blockchain ecosystem.

# Design of Manuscript

As the data access layer in the Chainbase network, Manuscript needs to interface with a large number of existing data protocols. Its core design philosophy revolves around modularity and scalability, consisting of the following key components:

![manuscript\_02.png](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/manuscript_02.png)

1. Accessor (Data Source):

* As the lowest-level interface, all services need to implement this interface, responsible for translating upper-layer calls into lower-level requests
* For example, translating a read request into corresponding service API calls
* Provides a unified data access abstraction, shielding the differences in underlying storage and services

2. Processor (Data Method):

* High-level methods oriented towards users, allowing them to conveniently create read and write requests
* Provides operations such as SQL syntax, initializing Datasets, etc.
* Encapsulates complex data interoperation underlying logic, providing a concise user interface

3. Handler (Data Target):

* Handles specific read and write requests, manages the lifecycle of data objects, implements data serialization and deserialization
* Deals with data consistency and concurrency issues
* For example, writing user-processed data to local relational databases like MySQL, PostgreSQL, etc.

4. Signer (Proof of Stake):

* Allows users to pre-generate signed URLs, supporting temporary authorized access, enhancing the security of data access
* Implements permission management and stake allocation proof interfaces based on smart contracts

# Manuscript Community

The Chainbase Network provides an open, trustless, and permissionless data ecosystem network, encouraging data democratization and monetization, where both users and data providers can participate without authorization from any governing body. Through Manuscript, participants can produce high-quality data and profit from it.

# Delegators
Source: https://docs.chainbase.com/introduction/networks/delegators



## Delegators

Delegators enhance the economic security of the network by staking their tokens to validators and operators. The Chainbase network uses a dual staking mechanism, where delegators can choose to stake `$ETH (or $LST)` and `$C`.

### Staking Tokens

Delegators can stake their tokens to support validators and operators, contributing to the network's security and stability.

## Developers

Developers are both the demand and supply side of the network's data. Developers build manuscripts and publish them to the network to earn rewards, and at the same time, when they build Dapps, they query network data, becoming users of the network.

### Local Development(Coming soon)

Developers use the `chainbase-sdk` to build manuscripts locally. The SDK provides a comprehensive set of tools and libraries that simplify the process of data transformation and querying.

#### Setting Up the Development Environment

To get started, developers need to set up their local development environment. This involves installing the necessary dependencies, configuring the SDK, and setting up a local blockchain node for testing.

1. **Install Dependencies**: Ensure you have Node.js and npm installed. Then, install the `chainbase-sdk` using npm:
   ```bash
   npm install chainbase-sdk
   ```
2. **Configure the SDK**: Create a configuration file to specify the connection details for your local blockchain node and other settings.
3. **Set Up Local Node**: Run a local blockchain node to simulate the network environment. This allows you to test your manuscripts in a controlled setting.
   refer to [how to run a node](xxx)

### Testing and Validation

After development, manuscripts can be deployed to our sandbox environment, where developers have the opportunity to validate their manuscripts in advance to ensure there are no indexing errors and that they work as expected.

#### Sandbox Environment

The sandbox environment mimics the main network but operates in isolation, allowing developers to test their manuscripts without affecting the live network. This environment provides tools for debugging and performance monitoring.

1. **Deploy Manuscripts**: Use the SDK to deploy your manuscripts to the sandbox environment.
2. **Run Tests**: Execute a series of tests to validate the functionality and performance of your manuscripts.
3. **Debugging Tools**: Utilize the provided debugging tools to identify and fix any issues.

### Publishing

When developers are satisfied with their manuscripts, they can publish them to the network. This is an on-chain operation that registers the manuscript so that indexers (operators) can discover it.

#### On-Chain Registration

Publishing a manuscript involves an on-chain deploy that registers the manuscript with the network. This process ensures that the manuscript is indexed and available for querying by other network participants.

1. **Prepare Manuscript**: Ensure your manuscript is finalized and thoroughly tested.
2. **Initiate deploy**: Use the SDK to initiate the on-chain deploy for publishing your manuscript.
3. **Confirmation**: Wait for the deploy to be confirmed on the blockchain. Once confirmed, your manuscript is officially published and indexed.

### Earning Rewards

By publishing manuscripts, developers can earn rewards based on the usage and value of their data transformations. The network incentivizes high-quality and frequently used manuscripts, providing a steady stream of rewards to active developers.

1. **Usage-Based Rewards**: Earn rewards based on the number of queries and the amount of data processed by your manuscripts.
2. **Quality Incentives**: High-quality manuscripts that provide valuable data transformations are eligible for additional incentives.

# The Age of AI Demands a New Data Economy

Data is the foundation of artificial intelligence.

As AI grows more autonomous and deeply embedded into digital infrastructure, high-quality data has become the most valuable asset.

Yet, current data systems aren't built for intelligent machines. Blockchain data remains fragmented, unstructured, unverifiable, and lacks pricing or incentive model. There's no native mechanism to value, trade, or coordinate data effectively.

Chainbase introduces a new standard: **Hyperdata Network**. Designed for the AI-native internet, it transforms raw blockchain activity into structured, composable, and machine-consumable data. It enables autonomous agents, protocols, and humans to access and coordinate through a shared data layer.

At the heart of this ecosystem is **\$C**. It powers AI and the broader DataFi economy.

## What is \$C?

\$C is the foundational asset of DataFi ecosystem, enabling the production, exchange, and governance of structured data across AI and crypto.
![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/tokenomics-1.webp)

### Core Utilities of \$C

#### Dataset Access

Agents, apps, and protocols use \$C to query and consume structured data.

#### Ecosystem Incentives

Distributed to developers, contributors, and users based on their activity and value to the network.

#### Decentralized Execution Security

Staked to support and validate data processing through the AVS layer.

#### Protocol Governance

Token holders vote on protocol upgrades, incentive models, and network parameters.

#### DataFi Currency

Serves as the standard unit of account and settlement across the Chainbase ecosystem.

## Token Distribution

Chainbase has allocated 65% of the total \$C supply to ecosystem growth, contributor rewards, and user incentives. This reflects Chainbase's commitment to open participation and long-term alignment.
![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/tokenomics-2.webp)

### Token Distribution Breakdown

* **Ecosystem + Community (40%)**: Reserved for grants, integrations, developer incentives, campaign rewards, and long-term community growth. This allocation supports open access and sustained participation in the Chainbase network.

* **Airdrop Incentives (13%)**: Distributed over three seasons to reward strategic partners (e.g: Season 1 allocates 3.5%, including 2% native community incentives and an additional 1.5% Binance Alpha), developers, users, project teams, and contributors who actively support ecosystem growth.

* **Worker Incentives (12%)**: Allocated to participants who operate data nodes and support Chainbase's decentralized infrastructure.

* **Early Backers (17%)**: For initial investors who provided early support and guidance to the project.

* **Core Contributors (15%)**: Reward for founding team members and core builders, with allocations optimally aligned with long-term protocol success.

* **Liquidity (3%)**: Reserved for exchange support and healthy market dynamics.

**Total supply**: 1,000,000,000 \$C

**Initial Unlocked Supply**: 16%

## Unlock Schedule

The \$C release model is structured to ensure long-term stability and meaningful participation.
![death spiral](https://mintlify.s3.us-west-1.amazonaws.com/chainbase/images/tokenomics-3.webp)

### Core Team & Early Backers

Tokens vest over 3 years, with a 12-month cliff followed by linear distribution over 24 months—designed to incentivize long-term contribution.

### Sustained Incentives for Infrastructure Operators

Worker Incentives, distributed to participants operating data nodes, vest linearly over 60 months, ensuring consistent support for the decentralized infrastructure that powers the Chainbase network.

### Ecosystem-Aligned Emissions

Tokens allocated to ecosystem development unlock linearly over 36 months, aligned with developer growth, incentive programs, and platform adoption milestones.

This phased rollout model allows \$C supply to expand in parallel with real usage, mitigates short-term speculation pressure, and reinforces sustainable participation in the DataFi economy.

## Launching on Base and BNB Chain

\$C will launch primarily on Base, with additional liquidity provided on BNB Smart Chain (BSC). This dual-chain approach enables the Chainbase ecosystem to:

* Leverage Base's performance, low fees, and strong developer ecosystem
* Provide access to broader liquidity and user base through BSC
* Cross-chain utility and trading

This approach ensures a smooth launch and positions Chainbase for long-term interoperability across Web3 ecosystems.

## Why \$C Matters

Data is no longer passive infrastructure. **It is capital**.

\$C turns raw data into an economic asset. It facilitates autonomous coordination, rewards real contributions, and enables an open, AI-ready data economy.

Chainbase provides the infrastructure. \$C brings it to life by making the infrastructure liquid, scalable, and usable to everyone.

## About Chainbase

## Installation Process

### Migration From Previous Version

If you've previously run a Chainbase AVS operator node:

1. You can delete old version `chainbase-avs-setup` directory on your server, but need to back up your encrypted **ECDSA** and **BLS** keys.
2. Skip the **EigenLayer Registration** step and only start from **Chainbase AVS Setup** step.

### EigenLayer Registration

Ensure you've registered with EigenLayer before proceeding. For guidance, refer to the [EigenLayer Operator Installation Guide](https://docs.eigenlayer.xyz/eigenlayer/operator-guides/operator-installation).

### Chainbase AVS Setup

1. Clone the Chainbase AVS setup repository:

```
git clone https://github.com/chainbase-labs/chainbase-avs-setup
```

run a Chainbase AVS operator node on mainnet (**invited and whitelisted**):

```
cd chainbase-avs-setup/mainnet
```

**OR** run a Chainbase AVS operator node on testnet (**no restrictions**):

```
cd chainbase-avs-setup/holesky
```

2. Set up the environment file:

```
cp .env.example .env
```

Configure all fields in the `.env` file with your specific information:

```
NODE_ECDSA_KEY_FILE_PATH=/your/ecdsa/key/path
NODE_BLS_KEY_FILE_PATH=/your/bls/key/path
OPERATOR_ECDSA_KEY_PASSWORD=yourECDSAKeyPassword
OPERATOR_BLS_KEY_PASSWORD=yourBlsKeyPassword
OPERATOR_ADDRESS=yourECDSAKeyAddress
NODE_SOCKET=yourNodeSocket
OPERATOR_NAME=yourOperatorName
```

Use the command `eigenlayer operator keys list` to retrieve information about your  **ECDSA** and **BLS** key paths and operator address.

* **OPERATOR\_ADDRESS**: Set to your operator address (must match your ECDSA key address).
* **NODE\_SOCKET**: Set to your server's public IP address (format: `<your_server_public_ip>:8011`).

Important:

* Ensure your server's public IP is internet-accessible.
* Verify that port 8011 is open and properly configured in your firewall settings.

# Inscription & Rune Data Support
Source: https://docs.chainbase.com/platform/datasets/inscription-and-rune



## Inscription & Rune Overview

Chainbase is built on the Streaming Warehouse prepared for the blockchain, constructing datasets in various fields. We hope to contribute to the Data field for BTC ecology under Inscription & Rune, making it easier and more efficient for developers to join the BTC ecosystem.

## Why Inscription & Rune is a Challenge from a Data Perspective in the Future

* Theoretically, all blockchains can run the Inscription protocol. Due to their low barrier to entry, throughput and storage will become challenges.
* The protocol is in its early stages, some indexers are still in the paper stage and have not been implemented. This requires infrastructure capabilities.
* The current implementation of indexers is more to solve the asset rights of Inscription & Rune off-chain, while the mining of blockchain data requires more capabilities.

## What has Chainbase done?

### Integrating Community Indexer

At present, Inscription & Rune generally open source protocol indexer, to ensure the legitimacy of off-chain asset verification and provide simple query services. Chainbase hopes to stay integrated with the community, continuously ingesting data into the Chainbase data platform to facilitate the re-mining of data value and create more data applications. At the same time, it can contribute code to the community's indexer.

![](https://files.readme.io/efa8bd6-image.png)

### Unify Data Abstraction Capability

Due to the lack of standardization in the Inscription & Rune's indexer, different indexer protocols use different languages and repeatedly build with different business logic. For example, all indexers will implement balance calculations related to the tick. The platform-based capability of chainbase can unify this part of data abstraction logic, integrating more inscription protocols at a lower cost.

![](https://files.readme.io/28b55ed-image.png)

### Make Developers Better Use Inscription & Rune Data

With the data platform capability based on chainbase, developers can explore more data value. For example

* Insight into investment opportunities on Inscription & Rune based on the product features of datacloud, such as the excavation of smart money
* The ability to actively push based on sync, develop robots based on message flow
* Integrate Inscription & Rune asset data into wallet applications and more based on web3 APIs

## What is Data Cloud?

The Chainbase Data Cloud lets you run your low-latency queries through an endpoint to leverage all our indexed datasets for your custom needs. Chainbase's [Data Cloud](/platform/datasets/overview) is a fully managed online data warehouse service for Web3 developers.  Developers can query the data warehouse through the **API** to access our datasets with zero infra cost.  And the **Data Cloud**'s scalable, distributed analytical data engine and intelligent data modeling allow you to query terabytes of data **in seconds**.

## Quickstart

Query the hashes of the last 3,000 blocks in Ethereum and the number of transactions in each block:

```bash
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
     -H 'X-API-KEY: YOUR-API-KEY ' \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
  "query": "select number, transactions_count from ethereum.blocks order by number desc limit 3000;"
}'
```

If there are more than 1000 rows, you need to paginate through the`task_id` and `page` to get all the results:

```bash
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
     -H 'X-API-KEY: YOUR-API-KEY ' \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
       "task_id": "xxxxxxxxxxxxxxxxxxxxx",
       "page": 2
}'
```

# Data Cloud Custom API (Alpha)
Source: https://docs.chainbase.com/platform/features/api/sql-api/datacloud-custom-api

A data request method supporting high-concurrency scenarios.

The Custom API functionality is designed to offer an efficient and reliable data processing solution, by automatically updating and persistently storing users' SQL query results according to a predetermined schedule in a relational database engineered to handle high concurrency and high throughput demands. This strategy, by sacrificing a certain degree of data real-time accuracy, achieves optimization in reducing response time and enhancing the number of requests processed. Compared to our Task API, the distinctiveness of the Custom API functionality lies in its less stringent requirement for data immediacy.

* **Task API**:  Asynchronous real-time requests with high data freshness (less concurrency scenarios).
* **Custom API**: High concurrency and low latency (with slightly reduced data freshness,at least 5 minutes).

## QuickStart

**Enter Data Cloud**: Access the [Data Cloud](https://console.chainbase.com/dataCloud) interface to start your data exploration.

**Input a Simple SQL Query**: Use the following SQL query in the Data Cloud to extract information from Ethereum transaction data, focusing on a specific block number:

```sql
select
    block_timestamp,
    block_number,
    _value,
    _from,
    _to
FROM ethereum.erc20_transfer
WHERE block_number = 17089970
```

This query retrieves details such as the timestamp of the block, block number, originating address, transaction value, and the transaction hash, specifically targeting transactions in block number 17089970 on the Ethereum blockchain.

**Execute the Query**: Run this query within Data Cloud to pull the specified data from the Ethereum blockchain.

![](https://files.readme.io/91fd400-image.png)

**Introduction to Custom Parameters**: In Data Cloud, you have the ability to use a dedicated parameter input box, which allows for the customization of query parameters. This feature enhances the flexibility and user-friendliness of SQL queries.

**Setting Up a Query with Custom Parameters**: Here’s an example of how you can structure an SQL query using a custom parameter for the block number:

![](https://files.readme.io/f7da96e-image.png)

```sql
SELECT
    block_timestamp,
    block_number,
    from_address,
    value,
    gas,
    hash
FROM ethereum.transactions
WHERE block_number = {blocknumber}
```

**Using the Custom Parameter Box**: When you run this query, use the custom parameter box to input or select the desired block number. This input will replace the {blocknumber} placeholder in the query, allowing you to retrieve data for that specific block on the Ethereum blockchain with ease.

![](https://files.readme.io/8249d4d-image.png)

**Save your query to File Explorer：**

After saving your SQL query, it will be visible and accessible at any time within the "File Explorer" on the left side. This tool is meticulously designed to simplify your navigation and management of saved queries. With easy access to these entries in the file management panel, complemented by the search functionality at the top, you can quickly locate and retrieve previously saved queries, significantly enhancing the efficiency of your development workflow in data analysis and database management. The "File Explorer" serves as a centralized platform for viewing and organizing SQL queries, further enabling developers to manage and execute data operations with great efficiency.

Finally, by clicking on "Generate API," you can create an API endpoint that allows you to invoke the data seen in Data Cloud within your own programs, offering a 'what you see is what you get' convenience. Additionally, you have the flexibility to select from different programming languages according to your tech stack, ensuring seamless integration into your development environment.

```typescript

const apiKey = "your-api-key";
const queryId = "424242";

const headers = {
  "API-KEY": apiKey,
  "CONTENT-TYPE": "application/json",
};

async function executeQuery(queryId) {
  return await fetch(
    `https://api.chainbasehq.com/v1/query/${queryId}/execute`,
    { method: "POST", headers }
  )
    .then((response) => response.json())
    .then((data) => data.data[0].executionId);
}

async function checkStatus(executionId) {
  return await fetch(
    `https://api.chainbasehq.com/v1/execution/${executionId}/status`,
    { headers }
  )
    .then((response) => response.json())
    .then((data) => data.data[0].status);
}

async function getResults(executionId) {
  return await fetch(
    `https://api.chainbasehq.com/v1/execution/${executionId}/results`,
    { headers }
  ).then((response) => response.json());
}

async function main() {
  const executionId = await executeQuery(queryId);
  let status;
  do {
    status = await checkStatus(executionId);
    await new Promise((resolve) => setTimeout(resolve, 1000));
  } while (status !== "FINISHED" && status !== "FAILED");

  return await getResults(executionId);
}

main().then(console.log);
```

## SQL Example

**Query the total cross-chain amount for a user:**

```sql
SELECT
    'out' as type,
    project,
    token,
    from_chain,
    to_chain,
    sum(cast(amount as decimal(38, 0))) as total
FROM
    bridge_ethereum.transfers
WHERE
    "from" = '0xf99d58e463a2e07e5692127302c20a191861b4d6'
group by
    project,
    token,
    from_chain,
    to_chain
UNION ALL
SELECT
    'in' as type,
    project,
    token,
    from_chain,
    to_chain,
    sum(cast(amount as decimal(38, 0))) as total
FROM
    bridge_ethereum.transfers
WHERE
    "to" = '0xf99d58e463a2e07e5692127302c20a191861b4d6'
group by
    project,
    token,
    from_chain,
    to_chain
```

This query consists of two parts: one part calculates the total amount of funds sent from a specific address (marked as 'out'), and the other part calculates the total amount of funds sent to that address (marked as 'in'). The two parts are combined using UNION ALL to provide a complete view of the total cross-chain transfer amount.

**Query the total liquidity provided by the user for each liquidity pool.**

```sql
select
    project,
    pool,
    token_address,
    sum(cast(amount as decimal(38, 0)))
from
    dex_ethereum.liquidity
where
    "from" = '{{UserAddress}}'
    or "to" = '{{UserAddress}}'
group by
    project,
    pool,
    token_address
```

**Query for token holdings**

```sql
select
    *
from
    ethereum.erc20_balances b
    left join ethereum.token_metas t on t.contract_address = b.contract_address
where
    wallet_address = '0x2e12979da9ad061ccc204c00d0e3a477a8cc4aea'
limit
    10
```

**Query the total amount of loans and collateral for a user.**

```sql
with
    lending_raw as (
        select
            project,
            asset,
            category,
            sum(cast(amount as decimal(38, 0))) as total_amount
        from
            lending_ethereum.feeds
        where
            account = '{{UserAddress}}'
        group by
            project,
            asset,
            category
    )
select
    project,
    asset,
    category,
    total_amount / t.decimals as volume,
    t.name
from
    lending_raw l
    left join ethereum.token_metas t on t.contract_address = l.asset
```

# Write Efficient Queries
Source: https://docs.chainbase.com/platform/features/datacloud/write-efficient-queries



## Tips for writing efficient queries

When you write a query, you want to make sure it runs as efficiently as possible. Here are some tips to help you write efficient queries:

1. **Limit the columns in the `SELECT` clause**: Only request the columns you need, as it reduces the amount of data the query engine needs to process.

2. **Use the `LIMIT` clause**: If you are only interested in a specific number of rows, use the `LIMIT` clause to avoid processing more data than necessary.

3. **Filter early and use predicate pushdown**: Apply filters as early as possible in the query to reduce the amount of data being processed. This takes advantage of predicate pushdown, which pushes filter conditions down to the storage layer, reducing the amount of data read from storage. For example, if you only need data from a specific date range, filter on the date column as early as possible.

4. **Use `UNION ALL` instead of `UNION`**: If you’re combining the results of multiple queries, use `UNION ALL` instead of `UNION` to avoid the overhead of removing duplicate rows.

5. **Only order when necessary**: Ordering results can be computationally expensive. If you don’t need ordered results, avoid using `ORDER BY`.

6. **Always use the actual data while filtering**: Do not use functions on the filter columns: For example, if you want to filter on a date, do not use date\_trunc('day', block\_timestamp) > '2022-01-01'. Instead, use block\_timestamp > '2022-01-01'. The first example will not be able to use the min/max values of the block\_time column to skip entire parquet files or row groups within files while scanning through a table, while the second example will. The same goes for other functions, such as substr, lower, upper etc.

7. **Use `UNION ALL` instead of `OR`**: If you need to combine the results of multiple queries, use `UNION ALL` instead of `OR` to avoid the overhead of removing duplicate rows. For example, instead of using `SELECT * FROM table WHERE column = 'value1' OR column = 'value2'`, use `SELECT * FROM table WHERE column = 'value1' UNION ALL SELECT * FROM table WHERE column = 'value2'`.

8. **User lower-case address directly in SQL**: If you are filtering on an address, use the lower-case address directly in the SQL query. For example, instead of using `SELECT * FROM transactions WHERE from_address = lower('0x1234567890ABCDEF')`, use `SELECT * FROM transactions WHERE from_address = '0x1234567890abcdef'`. This allows the query engine to use the min/max values of the from\_address column to skip entire ORC files or row groups within files while scanning through a table.

# Get native token balances by address
Source: https://docs.chainbase.com/platform/usecases/balance-api/get-native-token-balances



Getting the token balances of an account is an essential task when dealing with cryptocurrencies, as it allows you to know the amount of tokens that an account holds. The Web3 APIs from Chainbase provide the ability to get all transactions and account balances in a straightforward way. By following the steps below, you can seamlessly get the native token balances of an account on a certain chain through a single API call using Chainbase API.

## Overview - Tools you need to work with Chainbase

1. A free account at [Chainbase](https://www.chainbase.com) with an API key.
2. An IDE. Our examples are shown in JavaScript, you can use [VS Code](https://code.visualstudio.com/) as your IDE for example.
3. A known wallet address as your input.

## Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register [here](http://www.chainbase.com/register) for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the [dashboard](https://console.chainbase.com/) to get an overview. Create a new project in the console and get an API key.

![](https://files.readme.io/eb3531c-image.png)

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.

fetch(`https://api.chainbase.online/v1/account/balance?chain_id=${network_id}&address=${wallet_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/account/balance?chain_id=${network_id}&address=${wallet_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print native token balances

Chainbase API [Get native token balances](/api-reference/web3-api/balance/token-balances/get-native-token-balances) takes the chain id and wallet address as parameters, and returns the value of native token balances.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the native token balances of Vitalik’s wallet on Ethereum is `0x122b7e019d9a0431a15` by the time of Mar. 17th, 2023.

# Reverse Resolve ENS Domain
Source: https://docs.chainbase.com/platform/usecases/domain-api/reverse-resolve-domain



Reverse resolving an ENS name involves retrieving the address associated with a given ENS name. This can be useful in cases where you need to verify the ownership of an ENS name or interact with a smart contract associated with the name. By using Chainbase API [Reverse resolve ENS domain](/api-reference/web3-api/domain/ens-domain-endpoints/reverse-resolve-ens-domain), you can easily reverse resolve an ENS name and retrieve the associated address on Ethereum or other chains.

It's important to note that reverse resolving an ENS name only works for names that have been registered on the blockchain. If a name has not been registered, it will not have an associated address and therefore cannot be reverse resolved.

## Overview - Tools you need to work with Chainbase

1. A free account at [Chainbase](https://www.chainbase.com) with an API key.
2. An IDE. Our examples are shown in JavaScript, you can use [VS Code](https://code.visualstudio.com/) as your IDE for example.
3. A wallet address as your input.

## Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register [here](http://www.chainbase.com/register) for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the [dashboard](https://console.chainbase.com/) to get an overview. Create a new project in the console and get an API key.

![](https://files.readme.io/3e13e42-image.png)

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0x57511688c0ca7Cc7C25B90aE51C62B64652136Ac'; // Take our CTO Xiaocong's wallet address as an example.

fetch(`https://api.chainbase.online/v1/ens/reverse?chain_id=${network_id}&address=${wallet_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0x57511688c0ca7Cc7C25B90aE51C62B64652136Ac'; // Take our CTO Xiaocong's wallet address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/ens/reverse?chain_id=${network_id}&address=${wallet_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print the reversed resolved ENS domain

Chainbase API [Reverse resolve ENS domain](/api-reference/web3-api/domain/ens-domain-endpoints/reverse-resolve-ens-domain) takes the chain id and wallet address as parameters, and returns the reversed resolved ENS domain name.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the corresponding domain name of Xiaocong’s wallet on Ethereum is `lxcong`, which means you can get the wallet address using `lxcong.eth`.

```jsx
[
  {
    "address": "0x57511688c0ca7cc7c25b90ae51c62b64652136ac",
    "expiration_time": "2023-04-17T14:19:21Z",
    "name": "lxcong",

# Get all transfers of a NFT collection
Source: https://docs.chainbase.com/platform/usecases/nft-api/get-all-transfers-of-a-collection



If you're interested in tracking the transfers of an NFT collection, there are a few steps you can take to easily access this information. First, you need to find the contract address of the NFT collection you're interested in. You can usually find this on the collection's website or on a marketplace where the collection is listed. After you get the contract address, you can use Chainbase to view all the transactions related to that collection. With Chainbase API, you can easily access all the transfers of an NFT collection and gain valuable insights into the collection's activity.

Once you have these results, you can analyze the data to see who owns each NFT and when it was transferred. This can be useful for tracking the value of a particular NFT or for understanding the buying and selling patterns of a collection's community.

## Overview - Tools you need to work with Chainbase

1. A free account at [Chainbase](https://www.chainbase.com) with an API key.
2. An IDE. Our examples are shown in JavaScript, you can use [VS Code](https://code.visualstudio.com/) as your IDE for example.
3. An NFT contract address as your input.

## Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register [here](http://www.chainbase.com/register) for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the [dashboard](https://console.chainbase.com/) to get an overview. Create a new project in the console and get an API key.

![](https://files.readme.io/d07df31-image.png)

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take the contract address of Azuki as an example.

fetch(`https://api.chainbase.online/v1/nft/transfers?chain_id=${network_id}&contract_address=${contract_addr}&page=1&limit=5`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take the contract address of Azuki as an example.

const axios = require('axios');
const options = {

    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print all transfers of an NFT collection

Chainbase API [Get NFT owners by collection](/api-reference/web3-api/nft/nft-ownership/get-nft-owners-by-collection) takes the chain id and contract address as parameters, and returns all transfers of an NFT collection. You can also filter the results using constraints like block number and timestamp.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the first five transfers of Azuki on Ethereum are as follows by the time of Mar. 23rd, 2023.

```jsx

contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take Azuki's contract address as an example.
token_id = '1';

fetch(`https://api.chainbase.online/v1/nft/owner?chain_id=${network_id}&contract_address=${contract_addr}&token_id=${token_id}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take Azuki's contract address as an example.
token_id = '1';

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/nft/owner?chain_id=${network_id}&contract_address=${contract_addr}&token_id=${token_id}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print the owner of the NFT

Chainbase API [Get NFT owner by token](/api-reference/web3-api/nft/nft-ownership/get-nft-owner-by-token) takes the chain id, NFT contract address and NFT token id as parameters, and returns the owner address.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the address of `0xC8967D1537F7B995607A1DEa2B0C06E18A9756a2` is returned as the owner of the input NFT.

# Get NFT owners by collection
Source: https://docs.chainbase.com/platform/usecases/nft-api/get-nft-owners-by-collection



If you’re interested in the market of NFTs, it’s essential to know who the current owners of particular NFT collection are. Here are some steps to follow to get the owner information:

1. First, you need to identify the blockchain platform that the NFT collection is built on. Popular blockchain platforms for NFTs include Ethereum, Polygon, Binance Smart Chain, and so on.
2. Once you know the blockchain platform, you can use a blockchain explorer to search for the NFT contract address. A blockchain explorer is a tool that allows you to view transaction data on the blockchain.
3. After you find the NFT contract address, you can use Chainbase API [Get NFT owners by collection](/api-reference/web3-api/nft/nft-ownership/get-nft-owners-by-collection) to get all the owners of that NFT collection.

The following tutorial shows how to use Chainbase to get all the owners of a certain NFT collection. With this information, you can see who the largest holder of an NFT collection is.

## Overview - Tools you need to work with Chainbase

1. A free account at [Chainbase](https://www.chainbase.com) with an API key.
2. An IDE. Our examples are shown in JavaScript, you can use [VS Code](https://code.visualstudio.com/) as your IDE for example.
3. The contract address of a known NFT collection as your input.

## Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register [here](http://www.chainbase.com/register) for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the [dashboard](https://console.chainbase.com/) to get an overview. Create a new project in the console and get an API key.

![](https://files.readme.io/d0ae1d1-image.png)

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take Azuki's contract address as an example.

fetch(`https://api.chainbase.online/v1/nft/owners?chain_id=${network_id}&contract_address=${contract_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0xed5af388653567af2f388e6224dc7c4b3241c544'; // Take Azuki's contract address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/nft/owners?chain_id=${network_id}&contract_address=${contract_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print the owners of the NFT collection

Chainbase API [Get NFT owners by collection](/api-reference/web3-api/nft/nft-ownership/get-nft-owners-by-collection) takes the chain id and NFT contract address as parameters, and returns the holders’ address and the corresponding total. You can also get the total holder number in the `count` column of the returned data.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the `data` column of the returned data looks as follows.

```jsx
{
  "address": "0xd46c8648f2ac4ce1a1aace620460fbd24f640853",

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take MATIC token address as an example.

fetch(`https://api.chainbase.online/v1/token/holders?chain_id=${network_id}&contract_address=${token_addr}&page=1&limit=20`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take MATIC token address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/token/holders?chain_id=${network_id}&contract_address=${token_addr}&page=1&limit=20`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print token holders

Chainbase API [getTokenHolders](/reference/gettokenholders) takes the chain id and the contract address of a certain ERC20 token as parameters, and returns the holders of that token. You can also set the parameters `page` and `limit` to do the pagination and set the limitation.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the return data looks as follows. Note that since this API only returns unsorted token holders, query result may vary every time. If you want to get the top token holders, you can try another API called [getTopTokenHolders](/reference/gettoptokenholders).

```json
[

## Step 2: Write script using Chainbase API

1. Using `fetch` in JavaScript.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take MATIC token address as an example.

fetch(`https://api.chainbase.online/v1/token/top-holders?chain_id=${network_id}&contract_address=${token_addr}&page=1&limit=5`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
```

2. Using `axios` in JavaScript. You need to install `axios` using `npm install axios --save` in the terminal first.

```jsx
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
token_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take MATIC token address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/token/top-holders?chain_id=${network_id}&contract_address=${token_addr}&page=1&limit=5`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));
```

## Step 3: Print token holders

Chainbase API [Get top token holders](/api-reference/web3-api/token/token-holders/get-top-token-holders) takes the chain id and the contract address of a certain ERC20 token as parameters, and returns the top holders of that token. You can also set the parameters `page` and `limit` to do the pagination and get top holders.

To get data printed, run command `node <filename>.js` in the terminal. In this case, the return data looks as follows by Apr. 4th, 2023.

```json
{
  "count": 593525,
  "holders": [
    {
      "wallet_address": "0x5e3ef299fddf15eaa0432e6e66473ace8c13d908",

# Decentralized DORA Tuning
Source: https://docs.chainbase.com/theia/Developers/Glossary/D2ORA



### Abstract

$D^2ORA$ (Decentralized Weight-Decomposed Low-Rank Adaptation) extends the DoRA algorithm to a decentralized environment, enabling distributed training across multiple servers.

### $D^2ORA$ Algorithm

#### Step 1: Initialization

We first initialize the parameter matrices of Theia and the low-rank matrices.

* **Magnitude Vector Initialization**:
  Initialize the magnitude vector $m$ using the column-wise norm of the pre-trained weight matrix $W_0$:
  $$
  m = ||W_0||_c
  $$

* **Directional Matrix Initialization**:
  Set the directional matrix $V$ to the pre-trained weight matrix $W_0$:
  $$
  V = W_0
  $$

* **Low-Rank Matrices Initialization**:
  Initialize the low-rank matrices $B$ and $A$ for the LoRA method.

#### Step 2: Decomposition

Decompose the pre-trained weight matrix $W_0$ into its magnitude and direction components. The pre-trained weight is directly derived from the NLP model.

* **Magnitude Decomposition**:
  $$
  m = ||W_0||_c
  $$

* **Directional Decomposition**:
  $$
  V = W_0 / ||W_0||_c
  $$

#### Step 3: Distributed Training

For each server in the decentralized network, perform the following:

* **Distribution**:
  Distribute the initialized $m$, $V$, $B$, and $A$ to all servers.

* **Iterations**:
  For each iteration $t$ from 1 to $T$:

  * **Weight Update Calculation**:
    Compute the weight update $\Delta W$ using the low-rank adaptation method:
    $$
    \Delta W = BA
    $$

  * **Magnitude Vector Update**:
    Update the magnitude vector $m$:
    $$
    m = m - \eta \nabla_m L(m, V)
    $$

  * **Directional Matrix Update**:
    Update the low-rank matrices $B$ and $A$ with gradient descent:
    $$
    B = B - \eta \nabla_B L(B, A)
    $$
    $$
    A = A - \eta \nabla_A L(B, A)
    $$

#### Step 4: Aggregation

After all iterations are completed, collect updates from all servers and aggregate them:

* **Magnitude Vector Aggregation**:
  $$
  m' = \text{aggregate}(m)
  $$

* **Directional Matrix Aggregation**:
  $$
  V' = \text{aggregate}(V)
  $$

* **Low-Rank Matrices Aggregation**:
  $$
  B' = \text{aggregate}(B)
  $$
  $$
  A' = \text{aggregate}(A)
  $$

#### Step 5: Merging

Merge the updated components to form the final weight matrix:

* **Final Weights Calculation**:
  $$
  W' = m' \frac{V'}{||V'||_c} + B'A'
  $$

#### Step 6: Return Updated Weights

Return the updated weights $W'$ as the final output of the algorithm. We use it as the weight parameters of Theia.

### Summary

D^2ORA enhances the capabilities of DoRA by enabling decentralized training across multiple servers. This approach leverages blockchain technology to ensure trustworthiness, making it suitable for training AI models in a distributed and secure environment.


# Generate to Defend (G2D)
Source: https://docs.chainbase.com/theia/Developers/Glossary/G2D



## Necessity

For any AI models, adversarial attacks occur because attackers exploit vulnerabilities in the model's parameters by crafting inputs that cause the model to make incorrect predictions. These attacks are particularly effective when the model parameters remain static, allowing attackers ample time to probe and understand the model's weaknesses. The necessity of the Generate to Defend (G2D) algorithm arises from the need to counteract these attacks by periodically regenerating model parameters, thereby preventing attackers from gaining prolonged access to a consistent set of parameters. By continually altering the model parameters while maintaining performance, G2D disrupts the attackers' ability to reliably exploit the model, thus enhancing its robustness against adversarial threats, similar to frequently changing passwords to increase security.

### Generate to Defend (G2D) Algorithm

The G2D algorithm periodically generates new model parameters to prevent adversarial attacks by ensuring that the model parameters are not exposed for extended periods. The key idea is to tailor a diffusion model to create new parameters that maintain the model's performance while being sufficiently different from the original parameters. This is achieved by adding a regularizer to the diffusion process that maximizes the L1 distance between the generated parameters and the original parameters.

**1. Preliminaries of Diffusion Models:**

Diffusion models consist of forward and reverse processes indexed by timesteps. We summarize these processes below:

**Forward Process:**
Given a sample $x_0 \sim q(x)$, Gaussian noise is progressively added for $T$ steps to obtain $x_1, x_2, \ldots, x_T$. This process is described by:

$$
q(x_t | x_{t-1}) = \mathcal{N}(x_t; \sqrt{1 - \beta_t} x_{t-1}, \beta_t I)
$$

**Reverse Process:**
The reverse process aims to train a denoising network to remove the noise from $x_t$, moving backward from $x_T$ to $x_0$:

$$
p_\theta(x_{t-1} | x_t) = \mathcal{N}(x_{t-1}; \mu_\theta(x_t, t), \Sigma_\theta(x_t, t))
$$

The denoising network is optimized using the negative log-likelihood:

$$
L_{dm} = \text{KL}(q(x_{t-1} | x_t, x_0) \parallel p_\theta(x_{t-1} | x_t))
$$

**2. Embedding Model into Compact Space:**

To prepare the data, we train an autoencoder to extract latent representations of the model parameters. The encoding and decoding processes are formulated as:

$$
Z = f_{\text{encoder}}(V + \xi_V, \sigma)
V' = f_{\text{decoder}}(Z + \xi_Z, \rho)
$$

where $V$ is the set of model parameters, $Z$ is the latent representation, $\xi_V$ and $\xi_Z$ are added Gaussian noise, and $\sigma$ and $\rho$ are parameters of the encoder and decoder, respectively. The autoencoder is trained by minimizing the mean square error (MSE) loss:

$$
L_{MSE} = \frac{1}{K} \sum_{k=1}^K \| v_k - v'_k \|^2
$$

**3. Training Diffusion Models with Regularizer:**

We modify the diffusion process to include a regularizer that maximizes the L1 distance between the generated parameters and the original parameters. The training objective for the diffusion model with the additional regularizer is given by:

$$
\theta \leftarrow \theta - \nabla_\theta \left( \| \epsilon - \epsilon_\theta (\sqrt{\bar{\alpha}_t} z_k^0 + \sqrt{1 - \bar{\alpha}_t} \epsilon, t) \|^2 + \lambda \| \theta_{\text{gen}} - \theta_{\text{orig}} \|_1 \right)
$$

where $\lambda$ is a hyperparameter that controls the importance of the regularizer, $\theta_{\text{gen}}$ are the generated parameters, and $\theta_{\text{orig}}$ are the original parameters.

**4. Model Generation:**

During inference, random noise is fed into the trained diffusion model and decoder to generate new sets of model parameters:

$$
\theta_{\text{gen}} = f_{\text{decoder}}( \text{ReverseProcess}(\text{Random Noise}))
$$

These generated parameters are then used to replace the existing model parameters, ensuring the model's resilience against adversarial attacks by frequently updating its parameters. This modified diffusion process ensures that the new parameters are significantly different from the original ones, thereby enhancing the model's defense against adversarial attacks while maintaining its performance.

After the model is trained, the Step 4 is executed periodically to randomize AI model parameters, so that the cost of attack is significantly increased. The more frequent we generate, the safer our AI model become. To generate a new parameter, only a diffusion process is inferenced in a cost-effective manner.

# How to Create Task Models
Source: https://docs.chainbase.com/theia/TheiaChat/create-task-models



## Methodology

Theia Task Models is constructed using prompt and data engineering. We introduce these novel concepts including prompt engineering, RAG, and model self-tuning, which is used to build Theia Task Models.

### 1. Prompt Engineering

Prompt engineering refers to a series of instruction for Theia. It can trigger Theia to wake up specific capability in some field and work as a task model as instructed. The instruction should be clear and the output format can be defined. To build a good task model, we normally tell Theia three important messages: role, hint for reasoning and generation, and goal.

For example, to build a crypto investment advisor, we can write the prompt including the three messages:

* **Role:** Theia, you are an investment advisor.
* **Hint:** Whenever I provide you a whitepaper of a project, please analyze the whitepaper and search the news of this project.
* **Goal:** Then generate an investment advisory report.

Thus, the complete prompt is "Theia, you are an investment advisor. Whenever I provide you a whitepaper of a project, please analyze the whitepaper and news of this project. Then generate an investment advisory report."

### 2. Retrieval-Augmented Generation (RAG)

RAG is a method to integrates retrieval-based models with AI models, utilizing the intelligence of AI to analyze data and generate results according to specific objectives. It mainly consists of three steps:

* **Data Retrieval:** Retrieve relevant information from external datasets, e.g., the price variation of BTC in the past 3 months.
* **Task Objective:** Define the objective of RAG by prompt engineering, e.g., "find the buying and selling signals according to the MACD".
* **Augmented Generation:** Input the retrieved data into the Theia Task Model to get the augmented results.

Note that the data quality is one of the keys that decides the success of RAG. However, to obtain high-quality on-chain data, developers usually spent lots of time on extracting and aggregating data from blockchain. In Theia ecosystem, we are supported by Chainbase omnichain datanetwork, therefore providing massive high-quality data for users to build Theia task model in a cost-ffective and efficient fashion.

### 3. Model Self-Tuning

Though prompt engineering and RAG can utilize the capabilities of Theia, the intelligence of Theia is actually not improved in the parameter level, e.g., the intrinsic IQ of Theia. To really increase the IQ of Theia for higher-level task, model self-tuning is proposed. As our community uses Theia and its task models, many dialogues data are generated. They are the new "courses and books" Theia needs to read and learn. Furthermore, the developers are encouraged to upload manually labelled data that is also valuable to increase the Theia intelligence. The more data Theia sees, the higher intelligence it has.

The model self-tuning is based on the **Decentralized Weight-Decomposed Low-Rank Adaptation ($D^2ORA$)** algorithm that fine-tunes Theia periodically. The $D^2ORA$ algorithm focuses on updating the crypto-specific parameter matrix, ensuring that Theia Task Models continually enhance their expertise in the crypto domain as more and more users build task models upon Theia.

# Overview
Source: https://docs.chainbase.com/theia/TheiaChat/overview



TheiaChat is an AI agent built by Chainabse Labs based on Theia, the first crypto world model. TheiaChat provides an interface through which non-expert users can interact with the Chainbase Network, opening up the ability to obtain on-chain data intelligence to everyone for the first time.

Users can enhance the Chainabse Network when interacting with TheiaChat and benefit from it. This mainly involves two types of users:

1. **Non-Expert Users:** people without blockchain knowledge and skills, such as blockchain beginners. They can enhance the Chainbase Network by having conversations with TheiaChat and providing feedback on the results of the conversations, and the network rewards serious and honest users.
2. **Expert Users:** People with blockchain knowledge and skills, such as professional traders and security experts. They can enhance the Chainbase Network by building Theia Task Models in TheiaChat, and the network will reward Task Model builders with high adoption.

Chainbase Labs built the **Theia Security Model (TSM)** as an example to show the ability to build a Task Model based on the crypto world model Theia in TheiaChat. It is a security expert to offer advice in the crypto world, e.g., how to protect my wallet and money. It is constructed by training Theia with security books and community advice.

## How do interactions with TheiaChat enhance the Chainbase Network?

Every user interaction with TheiaChat and every task model built are enhancements to the under hood chainbase network. The basic logic is that these actions will directly trigger **Change Data Captures (CDCs, aka Changelog)**, and these contents are permanently stored on Arweave.

These are powerful complement to the Chainbase Network. It is also the first time that users can contribute data to enhance the Chainbase Network. Before this, only developers could enhance the network by building Manuscripts in the network. **This is the historical transformation of Chainbase Network from targeting 300,000 developers to targeting 30 million to 300 million users.**

In addition, every Changelog is a transaction on the Chainbase Network, which is permanently recorded on the Chainbase Network, and is public, censorship-resistant and cannot be manipulated. Its traceability guarantees the data income rights of every data producer.

# Features
Source: https://docs.chainbase.com/theia/World_model/features



In Web3, Theia excels with its native high performance, robust security measures, and transparent reasoning, making it a next-generation Crypto World Model tailored for the Web3 community.

#### 1. Crypto Native with High Performance

Theia is a native World Model for the crypto ecosystem, trained using the on-chain data from Chainbase hyperdata network and off-chain data from the Internet. It leverages a unique **Decentralized Weight-Decomposed Low-Rank Adaptation ($D^2ORA$) algorithm**, which allows for training a specialized crypto parameter matrix without modifying the parameters of the base natural language processing (NLP) model. By combining these parameters, Theia integrates the robust natural language capabilities of large language models (LLMs) with expert-level knowledge of both on-chain and off-chain crypto data. This results in superior Web3 attributes and performance compared to models like ChatGPT.

#### 2. Security

To enhance security, Theia employs generative AI to periodically update its digital persona. AI models are susceptible to attacks where adversaries can exploit model parameters to induce errors or generate targeted results. This vulnerability arises from the ability to reverse-engineer gradients from the model's parameters. Theia addresses this issue with an innovative **Generate to Defend (G2D)** algorithm, which uses generative diffusion models to capture and randomize the parameter space. This approach periodically refreshes Theia's parameters, preventing exhaustive attacks and model leaks with minimal cost.

#### 3. Transparency

Theia is built to be transparent through the extensive learning and summarization of crypto patterns from both on-chain and off-chain data. These patterns represent explicit rules inherent in the Web3 world. When users interact with Theia, they can transparently observe its reasoning process, ensuring reliability. Additionally, users have the ability to manually modify or add new patterns, allowing them to contribute their own crypto insights and perspectives, further enhancing Theia's intelligence.

# Theia
Source: https://docs.chainbase.com/theia/World_model/theia



We have developed a foundational **Crypto World Model (Theia)** on the Chainbase hyperdata network. Theia aims to transform vast amounts of on-chain dark knowledge into comprehensive intelligence for humans in a trustworthy manner. This is accomplished by distilling knowledge from both language models and the Chainbase hyperdata network through model training.

## How do we build Theia?

We propose a model tuning algorithm for Theia, **Decentralized Weight-Decomposed Low-Rank Adaptation ($D^2ORA$)** technique by revamping the [$DORA$ by NVIDIA](https://research.nvidia.com/publication/2024-07_dora-weight-decomposed-low-rank-adaptation), which decomposes a large language model into magnitude and direction components in a trustworthy manner. By feeding the model with on-chain data, we derive the crypto magnitude vector ($M_c$) and the directional matrix ($D_c$). The product of these components represents a crypto-oriented parameter matrix that encapsulates the extensive knowledge within the crypto space. The decentralized training approach ensures data security, model robustness, and result transparency. Consequently, the crypto knowledge is condensed into the crypto-oriented matrix, independent of the large language model (LLM), allowing it to be enhanced with future data or on-chain activities, thus evolving into an all-in-one expert in crypto.

## Capabilities of Theia

Unlike existing crypto AI projects, Theia offers a complete reasoning chain for question answering, providing transparent and trustworthy results. It learns crypto patterns from extensive on-chain and off-chain data and spatial-temporal activities, and its responses are based on causal reasoning with these crypto patterns. Ultimately, Theia consists of a powerful LLM parameter matrix operating with the crypto-oriented parameter matrix and crypto patterns. To ensure up-to-date intelligence with reliable arguments, we integrate Theia with the real-time hyperdata network and an Internet AI reader via Retrieval-Augmented Generation (RAG). Leveraging Theia's intelligence, users can also build task-specific AI models on top of it.

## Summary

Theia represents the next generation of Crypto World Models, derived from model training using the novel $D^2ORA$ algorithm and crypto patterns identified by machine intelligence. It offers transparent and trustworthy knowledge to the web3 community, illuminating the hidden knowledge within the crypto world.


# Welcome
Source: https://docs.chainbase.com/theia/World_model/welcome



Chainbase is building an crypto world model, Theia, which is designed to learn blockchain data and realize simulation and reasoning of the native blockchain environment. Agents built based on it can effectively understand, predict and interact with the blockchain.

Chainbase assembled a team led by a professor in the field of AI to build the model to support native crypto applications, including AI crypto games, DeFi, security, social, asset management, and more.

## What is Crypto World Model?

The crypto world is built on massive and rapidly growing blockchain data, which contains an abundance of knowledge and underlying opportunities. Chainbase continually extracts, records, and organizes this data, summarizing it for downstream users. However, a significant and persistent challenge is that the vast "dark knowledge" within crypto data cannot be effectively organized solely through traditional databases and limited human effort. Accessing and interpreting this knowledge easily and conveniently remains a challenge for crypto participants.
