Official golang implementation of the Bytom Sidechain protocol.
Automated builds are available for stable releases and the unstable master branch. Binary archives are published at https://github.com/Bytom/bmc/releases.
Bytom sidechain is a high-performance layer 2 scalability solution that is compatible with EVM (Ethereum Virtual Machine) and OFMF (Open Federation Management Framework) cross-chain.
- High-performance: High speed of transaction and low transaction fee.
- EVM-compatible: Supports Ethereum developing ecosystem and tools.
- OFMF Cross-chain: Supports cross-chain with Bytom, Bitcoin and Ethereum.
- Go version 1.8 or higher, with
$GOPATHset to your preferred directory
Ensure Go with the supported version is installed properly:
$ go version
$ go env GOROOT GOPATH- Get the source code
git clone https://github.com/Bytom/bmc.git $GOPATH/src/github.com/bytom/bmc- Build source code
cd $GOPATH/src/github.com/bytom/bmc

geth |
Main Bytom Side Chain client binary. It is the entry point into the BMC network，capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It has the same and more RPC and other interface as go-ethereum and can be used by other processes as a gateway into the BMC network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. geth --help and the CLI page for command line options. |
