本文主要是介绍Hyperledger Besu(1)“系统框架”,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

1. 定义

是一个运行在以太坊公网上的java语言的以太坊客户端,旨在对公共和私有许可网络用例进行企业友好。它也可以在 Rinkeby、Ropsten 和 Görli 等测试网络上运行。

1.1 功能

  • 在以太坊区块链中处理交易的执行环境
  • 用于持久化与事务执行相关的数据的存储
  • 点对点 (P2P) 网络,用于与网络上的其他以太坊节点通信以同步状态
  • 应用程序开发人员与区块链交互的 API

1.2 实现了规范 企业以太坊联盟 EEA(Enterprise Ethereum Alliance) 规范

1.3 核心模块

  • 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.
    监控运维:区块链浏览器
