以太坊虚拟机 (EVM)The Ethereum Virtual Machine (EVM)
Consensus algorithms: in addition to a proof-of-work algorithm, Besu also features several proof-of-authority protocols, which are well suited for use in blockchain consortia or other private networks where the participants know one another.
共识协议:POA, 多种权威证明协议 -
P2P networking: by leveraging Ethereum’s devp2p network protocols, Besu is able to facilitate inter-client communication.
P2P网络:devp2p 网络协议 -
Storage: Hyperledger Besu utilizes a RockDB key-value database to persist chain data locally. The data is divided into two sub-categories – blockchain data and world state data.
存储:RockDB
区块链数据和世界状态数据 -
Permissioning: while Besu leverages the public Ethereum mainnet, it also provides businesses with the means to create permitioned networks by specifying which nodes and accounts can participate in those networks.
身份准入 -
Privacy: Besu uses a Private Transaction Manager to ensure the privacy of transactions between counterparties.
隐私 -
User-facing API: the client provides mainnet Ethereum and EEA JSON-RPC APIs over HTTP and WebSocket protocols. It also supports a GraphQL API.
用户api ,支持GraphQL API. -
Monitoring: Hyperledger Besu utilizes tools such as Prometheus and Block Explorer to allow for users to monitor node and network performance, respectively.
