XuperChain, the first open source project of XuperChain Lab, introduces an underlying solution to build the super alliance network, based on the dynamic kernel of xupercore. You can use xuperchain 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 parallel.
  • 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 1.14.x or later
• GCC 4.8.x or later
• Git

Clone the repository

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

Note:

master branch contains the latest features but might be unstable.

For production use, please check out the latest release.

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 & 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

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

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