RepChain文档 单机多节点部署 多机多节点部署


  • RepChain免编译版本下载 ——为方便用户使用,提供了免编译版本,此版本不需要编译即可直接运行
  • 前置条件
    • 需要机器上安装java13,并配置好环境变量
    • 单机多节点解压后使用启动脚本 (start.sh或start.cmd),linux/mac使用start.sh,,win系统双击start.cmd
    • 多机多节点使用启动脚本(start01.sh至start05.sh或start01.cmd至start05.cmd),启动前需要修改配置文件


  • akka ——系统内部模块采用akka actor实现
  • akka remoting security ——节点之间安全通信采用akka Remote支持的TLS
  • akka serialization——节点之间消息交互采用protobuf序列化
  • scalaPB——从proto定义生成Scala类的工具
  • protobufjs——在web端根据proto定义,反序列化protobuf字节流
  • swagger-scala——API支持Swagger UI
  • json4s——在API层提供输入对象的json反序列化,返回结果的json序列化
  • d3.js-force layout——入/离网节点的自动布局
  • leveldb for java——存取Blocks、Transactions索引
  • java security——hash、签名、密钥对及证书管理均采用jdk内置方法




  • 数据层:负责数据格式定义,数据结构采用Protocol Buffers定义文件,并以此为基础实现数据的交换、验证、存储、读取及检索
  • 网络层:采用JDK内置的TLS实现,支持入网许可验证,在此基础上进行去中心化的gossip组网,网络传播支持P2P和Pub/Sub两种方式
  • 共识层:完成区块的输入共识和输出共识。采用兼顾实时性和安全性的CFRD算法,既照顾到交易的实时性要求,又能在一定程度防止节点串通作弊;输入共识对入块的交易顺序达成一致,输出共识对交易顺序执行的结果达成一致
  • 合约层:为合约执行提供上下文环境,支持合约的动态部署、运行时加载和编译执行
  • API层:提供外部接口,允许第三方应用以Restful的形式与系统交互,并允许开发者通过Swagger UI进行在线测试。API层提供交易签名提交、区块和交易检索等基本功能
  • 监控层:在区块链网络中收集事件/日志,并将其以Protocol Buffers的格式推送至Web端,以H5图形技术进行实时状态的可视化展示和日志回放




  • assembly
    • 打包成jar包,进行分布式部署


  • BAR(Base App of RepChain):提供了通用的基础功能实现,区块链应用实施者既可以直接复用其提供的功能, 也可以在其源代码的基础上进行开发,快速开发自己的DAppp
  • SBR(Storage Based on RepChain):基于BAR开发的可举证云存储应用示例
  • CRBB(Copyright Register Based on Blockchain):基于RepChain的数字版权登记保护应用示例
