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.

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

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

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

Please refer to our wiki for more information, including how to build multi-node network, transfer to others, deploy and invoke smart contract.
