What is XuperChain

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.

Quick start


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


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

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

Use Docker to build xuperchain see docker build


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

Run with Docker

Build image

docker build . -t xuperchain

Run image

# 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 status

This 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.

We have new documentation of Chinese version at XuperChain Chinese Docs, the English version is comming soon.
