Discover CometBFT, the consensus engine powering Berachain. Learn how this innovative technology ensures network safety and consistency, enabling efficient development and deployment of decentralized applications on a high-performance, EVM-compatible blockchain.
Introduce Berachain
Berachain is a high-performance, EVM-compatible blockchain built on the innovative Proof-of-Liquidity (PoL) consensus mechanism. This new consensus model aims to balance network incentives, fostering robust interactions between Berachain validators and the ecosystem’s projects. Berachain’s technology is constructed on the Polaris blockchain framework and the CometBFT consensus engine, supporting Ethereum’s smart contract tools while introducing additional functionalities for decentralized applications.
Leveraging the Polaris framework and the CometBFT consensus engine, Berachain supports Ethereum’s smart contract operations and offers enhanced features for decentralized applications. Known as an “EVM-plus” blockchain, Berachain combines EVM compatibility with advanced features, making it a powerful choice in the blockchain space. Its design, supported by the Cosmos-SDK, provides flexibility and diversity, catering to developers and users who demand advanced and efficient blockchain solutions.
In summary, Berachain is built on the Cosmos SDK framework with key elements including:
- High compatibility with EVM (Ethereum Virtual Machine).
- Utilization of the Proof-of-Liquidity consensus mechanism as an alternative to Proof of Stake.
- Adoption of the CometBFT consensus algorithm.

CometBFT Consensus
CometBFT is a software solution that ensures the safe and consistent replication of applications across multiple machines. It maintains security as long as fewer than one-third of the machines are faulty, and consistency is achieved by ensuring all non-faulty machines have access to the same transaction log and compute the same state. This type of replication is crucial in distributed systems, significantly enhancing the fault tolerance of various applications, from cryptocurrencies to infrastructure coordination.
Byzantine Fault Tolerance (BFT) is a concept that allows systems to handle faults in arbitrary ways, even when machines become malicious. While BFT theory has existed for decades, it has recently gained popularity due to the success of blockchain technologies like Bitcoin and Ethereum. Blockchain technology modernizes BFT by focusing on a peer-to-peer network and cryptographic verification. The term “blockchain” comes from the way transactions are batched into blocks and linked together to form a chain.
CometBFT consists of two main technical components:
- Blockchain Consensus Engine: Based on the Tendermint consensus algorithm, it ensures all machines record transactions in the same order.
- Application BlockChain Interface (ABCI): Provides transactions for applications to process.
Unlike other blockchain and consensus solutions that come with integrated state machines, CometBFT allows developers to use it to replicate the BFT state machines of applications written in any programming language and development environment that suits their needs. CometBFT is designed to be user-friendly, easy to understand, high-performing, and useful for various distributed applications.
