Hyperledger Besu Consensus Algorithms
Hyperledger Besu supports several consensus algorithms, including:
- Proof of Work (PoW): Proof of Work is a consensus algorithm used in public Ethereum networks and is the default consensus algorithm for Hyperledger Besu when running in public mode. It uses mining to reach a consensus on the state of the blockchain.
- Clique PoA (Proof of Authority): Clique PoA is a consensus algorithm used in private Ethereum networks, where a set of authorized nodes, or authorities, validate transactions and blocks. It is more suitable for private networks where the identities of the validating nodes are known and can be trusted.
- IBFT 2.0 (Istanbul Byzantine Fault Tolerance): Istanbul Byzantine Fault Tolerance is a consensus algorithm used in private Ethereum networks that provides high performance and finality. It is a BFT-style consensus algorithm that uses voting by validating nodes to reach consensus.
- Aura PoA (Proof of Authority): Aura PoA is a consensus algorithm used in private Ethereum networks where a single authority is responsible for validating transactions and blocks. It is suitable for networks where a single entity needs to have complete control over the validation process.
Hyperledger Besu in Blockchain
Hyperledger Besu is an open-source blockchain platform developed under the Hyperledger project of the Linux Foundation. It is designed to provide a robust, secure, and highly performant platform for building decentralized applications (dApps) and smart contracts.
