blockj

Java 实现的一个简易区块链(联盟链)项目,包括加密工具,钱包,P2P 传输,区块同步,网络共识等基础实现。 它使用 SpringBoot + Tio 网络框架实现,是一个非常好的区块链学习项目,目前只实现了 POW 共识算法,如果要用于生产项目需要根据自己的项目需求修改共识。


项目架构

主程序使用 SpringBoot 实现, P2P 传输这块使用的是 t-io 网络框架

项目模块

  • blockj-base 基础公共的工具包,如加密,区块,消息等数据模型,数据存储等。
  • blockj-miner 区块链主程序,如矿工,区块同步,P2P 网络,RPC API 等。
  • blockj-client 客户端命令行工具,主要就是调用 Miner 的相关 API,用户跟链交互。

快速开始

创建一条链的操作流程如下:

  1. 创建创世节点(创建一个网络)
  2. 启动创世节点(Genesis Miner)
  3. 其他节点要加入网络的话,只需要以创世区块初始化 Miner,然后再启动 Miner 即可。

创建创世节点

首先我们需要编译打包程序:

git clone https://gitee.com/blackfox/blockj.git
cd blockj
mvn clean package

然后创建创世节点:

./miner genesis --repo=/data/genesis --enable-mining=true

启动创世 Miner:

./miner run --repo=/data/genesis 

启动新 Miner

首先需要初始化 miner,需要导入创世区块(genesis.car)来加入网络:

./miner init --repo=/data/miner1 --genesis=genesis.car --api.port=8002 --p2p.port=3456

启动 Miner

./miner run --repo=/data/miner1

TODOLIST

  • blockj-miner api 实现
  • 消息同步和打包
  • blockj-client(客户端)功能实现:网络,钱包,转账
  • 文档完善
  • 添加 PBFT 共识支持
