License Maven Central Build Status

一个面向企业应用场景的通用区块链框架系统,能够作为企业级基础设施,为业务创新提供高效、灵活和安全的解决方案。

源码构建

JD Chain源码通过gitgit submodule进行管理,如下操作可快速构建:

$ git clone https://github.com/blockchain-jd-com/jdchain.git jdchain

$ cd jdchain

# 此处仅以 master 分支为例,正常情况下 master 分支可无障碍构建成功
# 不推荐使用 develop 分支,submodule 代码可能未对齐
# 推荐切换到具体已发布的版本分支
$ git checkout master

$ chmod +x build/*.sh

# 执行完整的构建,包括执行”集成测试“和”打包“两部分;提供两个参数:
# --skipTests :跳过集成测试部分; 
# --update :从远程仓库更新子模块。注意,采用此参数会导致子模块本地仓库丢失尚未 commit 的代码。
#           不附带此参数的情况下不会更新子模块仓库。
$ build/build.sh --update

# 跳过子模块代码更新和集成测试,直接编译和打包;
$ build/build.sh --skipTests

# 首次代码拉取,跳过集成测试和编译打包可执行:
$ build/build.sh --update --skipTests

构建完成后会在deploy模块,deploy-gatewaydeploy-peer目录target中生成网关安装部署包(jdchain-gateway-*.zip)和共识节点安装部署包(jdchain-peer-*.zip)。

部署使用

快速部署

使用源码构建生成的部署安装包,或者下载官方部署安装包 参照快速部署文档可快速部署运行JD Chain网络。

数据上链

  1. 命令行工具

JD Chain 命令行工具集,即jdchain-cli,可快速执行数据上链和链上数据查询。

  1. SDK

JD Chain提供了JavaGo版本的SDK。实际项目开发中Java可参照示例代码Go语言SDK参照framework-go
