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

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 v3.4.
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
There is an output folder if build successfully. Enter the output folder, create a default chain firstly:
cd ./output
./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 XuperChain 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
docker build . -t xuperchain# run xchain daemon
docker run -d -p 37101:37101 -p 47101:47101 --rm --name xchain xuperchain
# enter running container
docker exec -ti xchain bash
# run command
./xchain-cli statusThis is only a demo for local single container, you can use volume to mount and overwrite configurations.
Please refer to our wiki for more information, including how to build multi-node network, transfer to others, deploy and invoke smart contract.

编译
cd xuperchain
make
跑单测
make test
单机版xchain
cd ./output
./xchain-cli createChain
nohup ./xchain &
./xchain-cli status
docker build . -t xuperchain# 运行容器 daemon
docker run -d -p 37101:37101 -p 47101:47101 --rm --name xchain xuperchain
# 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。
