# Module Introduction

### **Data Accessibility Layer**

[Data Accessibility Layer](/network/core-concepts/architecture/data_accessibility_layer) manages data access and storage in the network, is compatible with data access interfaces for both streaming and batch scenarios, and provides data validity verification. It includes:

* **Data Access Interface:** Provides access to both batch and streaming data.
* **Data Storage:** Supports various storage solutions, including Lakehouse, Arweave, S3, and IPFS.
* **Data Proof:** Implements zk-proofs and storage-based consensus paradigms to ensure data integrity and availability.

### **Consensus Layer**

[Consensus Layer](/network/core-concepts/architecture/consensus_layer) ensures that all nodes in the network reach a consensus on data and status consistency, based on CometBFT's instant finality, achieving second-level data freshness. Including:

* **Consensus Algorithm:** Based on CometBFT and DPoS (Delegated Proof of Stake) to achieve efficient and secure consensus.
* **ABCI++:** An extension of Cosmos network's ABI, responsible for converting the state of the Chainbase Virtual Machine (CVM) to a format compatible with the CometBFT consensus engine.
* **Stake Aggregator:** Aggregates staked tokens from various Cosmos ecosystem sources to ensure network security.

### **Execution Layer**

[Execution Layer](/network/core-concepts/architecture/execution_layer) is responsible for large-scale data processing and execution of Manuscripts' data transformation logic. Including:

* **Chainbase Virtual Machine (CVM):** A virtual machine that provides parallel computing capabilities to execute Manuscripts
  * **Parallel Execution Engine:** Utilizes multithreading for parallel data processing, enhancing performance and throughput.
  * **ChainbaseDB (CDB):** A database system that supports multiple data storage engines, including VectorDB, GraphDB, and KV storage.
* **Eigenlayer AVS (Proof Verification System):** Introducing the Ethereum economic security brought by Restake, making the CVM running environment fully decentralized

### **Co-processor Layer**

Chainbase has introduced the [Co-processor Layer](/network/core-concepts/architecture/co_processor_layer) to facilitate user collaboration in data processing and AI expertise. This layer allows users to transform their specialized knowledge into tradeable assets, managed and incentivized through the \$C token system, creating a dynamic ecosystem. This design enhances data accessibility and encourages developer collaboration, accumulating knowledge and generating collective intelligence, thereby unlocking greater potential for blockchain technology.

### **Dual Staked Security**

This module enhances the network security of the consensus layer and execution layer in the dual-chain architecture through a double staked mechanism. Including:

* Shared Staked Pool:
  * Native Token Stake: \$C native token captures network value
  * Eigenlayer Restake: Introduces Ethereum tokens with low volatility and deep liquidity
* Double Staked Model: By aggregating all validators' stake and their power mapping for various assets, the total cryptographic economic security is calculated.

### Manuscript

[Manuscript](/resources/manuscript/overview) defines the standard schema that different data sources need to follow when converting into datasets.

### CVM Interface

The CVM Interface provides a set of standardized interface protocols for interacting and communicating with CVM, allowing developers to write and manage Manuscripts on the network, as well as access Dataset in the data network.
