What is XuperUnion

XuperUnion, the first open source project of XuperChain, introduces a highly flexible blockchain architecture with great transaction performance.

XuperUnion is the underlying solution for union networks with following highlight features:

• High Performance

  • Creative XuperModel technology makes contract execution and verification run parallelly.
  • TDPoS ensures quick consensus in a large scale network.
  • WASM VM using AOT technology.

• Solid Security

  • Contract account protected by multiple private keys ensures assets safety.
  • Flexible authorization system supports weight threshold, AK sets and could be easily extended.

• High Scalability

  • Robust P2P network supports a large scale network with thousands of nodes.
  • Branch management on ledger makes automatic convergence consistency and supports global deployment.

• Multi-Language Support: Support pluggable multi-language contract VM using XuperBridge technology.

• Flexibility: Modular and pluggable design provides high flexibility for users to build their blockchain solutions for various business scenarios.

Quick start

Requirements

• OS Support: Linux and Mac OS
• Go 1.12.x or later
• GCC 4.8.x or later
• Git

Build

Clone the repository

git clone https://github.com/xuperchain/xuperunion

Enter the xuperunion folder and build the code:

make

Note that if you are using Go 1.11 or later, go modules are used to download 3rd-party dependencies by default. You can also disable go modules and use the prepared dependencies under vendor folder.

Run test:

make test

Run

There is an output folder if build successfully. Enter the output folder, create a default chain firstly:

./xchain-cli createChain

By doing this, a blockchain named "xuper" is created, you can find the data of this blockchain at ./data/blockchain/xuper/.

Then start the node and run XuperUnion full node servers:

nohup ./xchain &

By default, the xuper chain will produce a block every 3 seconds, try the following command to see the trunkHeight of chain and make sure it's growing.

./xchain-cli status

Run with Docker

Build image

docker build . -t xuperunion

Run image

# run xchain daemon
docker run -d -p 37101:37101 -p 47101:47101 --rm --name xchain xuperunion
# enter running container
docker exec -ti xchain bash
# run command
./xchain-cli status

This is only a demo for local single container, you can use volume to mount and overwrite configurations.

构建

克隆XuperUnion仓库

git clone https://github.com/xuperchain/xuperunion

编译

cd xuperunion
make

跑单测

make test

单机版xchain

./xchain-cli createChain
nohup ./xchain &
./xchain-cli status

容器运行

编译镜像

docker build . -t xuperunion

运行镜像

# 运行容器 daemon
docker run -d -p 37101:37101 -p 47101:47101 --rm --name xchain xuperunion
# 进入容器
docker exec -ti xchain bash
# 运行指令
./xchain-cli status

本地容器化运行的示例，实际场景中可以用卷的方式挂载并覆盖配置。
