Consensus Layer

The consensus is a foundational component of the BitAcross network, designed to enhance the interoperability and liquidity of Bitcoin-based assets like BRC-20 tokens. This consensus Layer plays a pivotal role in ensuring both public auditability and maintaining robust security within the network. Here are the key functionalities and features of the consensus layer:

  • Node Composition: The consensus layer is composed of multiple nodes, which work together to maintain the network's integrity and performance. These nodes are responsible for processing transactions, maintaining the blockchain, and ensuring the network's overall health and efficiency.

  • Decentralized Attestation for TEE Nodes: It provides remote and decentralized attestation for Trusted Execution Environment (TEE) Nodes. This feature is crucial for verifying the integrity and security of the TEE nodes, ensuring they operate correctly and securely.

  • Public Auditability: The consensus layer offers public auditability for all registered information and transaction data. This transparency is key to maintaining trust among users and for the verification of transactions and state changes on the network.

  • Data Availability Layer: Serving as the data availability layer, the BitAcross consensus layer ensures that all transactions and state transitions are agreed upon by the network nodes, thereby maintaining the blockchain's consistency and reliability.

  • Governance and Enclave Upgrade Logic: The consensus layer incorporates governance mechanisms to manage and initiate upgrades to the network, particularly regarding the enclave logic. This governance ensures that changes to the network are made democratically and in line with the community or stakeholders' consensus.

  • Support for EVM Smart Contracts: One of the critical features of the consensus layer is its support for Ethereum Virtual Machine (EVM) smart contracts. This allows for a wide range of applications and functionalities to be built and executed on the consensus layer, expanding its use cases beyond simple asset transfers.

  • State Update and Execution Integrity: The network is designed to ensure that the state is only updated, and execution proceeds strictly in accordance with the predefined application logic. This feature is vital for maintaining the correctness and predictability of the network's operations.

  • Protocol Liveness: The design of the BitAcross consensus layer ensures the continuous operation of the protocol, preventing it from being halted or disrupted by any single party. This resilience is crucial for maintaining the network's availability and reliability.

Overall, the BitAcross consensus layer is engineered to provide a secure, transparent, and efficient platform for cross-chain interactions, particularly focusing on enhancing the capabilities of Bitcoin-based assets in the broader blockchain ecosystem.
