blockchain's Introduction

基于Golang的PBFT共识多节点区块链系统

复旦大学2023年秋季学期区块链技术(COMP130200.01)期末课程项目

实现基于Golang的PBFT共识多节点区块链系统

功能要求:

  1. 多节点协作和网络通信: 创建多个节点,每个节点能够通过网络通信。使用合适的RPC方式确保支持以下区块链交互指令:

    1. 添加新交易到待处理池;
    2. 提交区块到共识过程;
    3. 获取特定交易或区块的信息;
    4. 执行节点之间的同步操作;
  2. 数据结构和存储: 实现交易、区块和区块链的数据结构,并提供数据库或文件存储机制来持久化这些数据;

  3. PBFT共识: 集成PBFT作为共识机制,实现PBFT算法中的预准备、准备、提交等步骤,可以处理拜占庭错误;

  4. 轮换主节点: 提供主节点轮换机制;

  5. 交易验证: 实现ECDSA签名验证,以确保交易的真实性和完整性。

开发要求:

  1. 使用Golang编程语言,利用其并发编程特性来构建多节点区块链系统;
  2. 确保系统具备足够的并发能力,以支持高效的区块链交互和PBFT共识算法;
  3. 可以合理使用第三方库来加速开发,提高系统的稳定性和性能;
  4. 允许使用AI工具,但需理解代码设计,并在项目报告中说明;

测试:

编写必要的测试用例来验证系统的功能和安全性,包括正常操作、异常情况下的处理和共识的正确性
