What is XuperChain

XuperChain, the first open source project of XuperChain Lab, introduces a underlying solution to build the super alliance network. Based on the dynamic kernel of xupercore. You can use xuberchain as a blockchain infrastructure to build a compliant blockchain network.

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

• Dynamic kernel

  • Based on the dynamic kernel technology, the free extension kernel components without kernel code intrusion and lightweight extension customized kernel engine are implemented to meet the needs of blockchain implementation for various scenarios.
  • It provides a comprehensive and high-performance implementation of standard kernel components.
  • Comprehensively reduce the cost of blockchain research and development, and open a new era of one click chain development.

• 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/xuperchain

Note: master branch contains latest features but might be unstable. for production use, please checkout our release branch. the latest release branch is v3.7.

Enter the xuperchain folder and build the code:

cd xuperchain
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

Run single node blockchain

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

cd ./output
sh control.sh start

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

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.

./bin/xchain-cli status

Run multi nodes blockchain

Generate multi nodes. Before running the following command, make sure you have run make to make the code.

make testnet

Enter the testnet directory, and then start three nodes separately (make sure the port is not used)

cd ./testnet/node1
sh ./control.sh start
cd ../node2
sh ./control.sh start
cd ../node3
sh ./control.sh start

Observe the status of each node

./bin/xchain-cli status -H :37101
./bin/xchain-cli status -H :37102
./bin/xchain-cli status -H :37103

构建

克隆XuperChain仓库

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

注意: master 分支是日常开发分支，会包含最新的功能，但是 不稳定。生产环境请使用最新的已发布分支，最新的已发布分支是v3.10。

编译

cd xuperchain
make

跑单测

make test

单机版xchain

cd ./output
sh ./control.sh start
./bin/xchain-cli status

多节点xchain

生成多节点。 在运行下面的命令之前，请确保已经运行make去编译代码。

make testnet

进入testnet目录，分别启动三个节点(确保端口未被占用)。

cd ./testnet/node1
sh ./control.sh start
cd ../node2
sh ./control.sh start
cd ../node3
sh ./control.sh start

观察每个节点状态

./bin/xchain-cli status -H :37101
