The Ethereum C++ client.

The cpp-ethereum / Ethereum C++ client project was initiated by Gavin Wood, the former CTO of the Ethereum Foundation, in December 2013. It is the second most popular of the clients with around 5% of 'market share', trailing a long way behind go-ethereum.

It includes:

  • eth A command-line Ethereum full-node that can be controlled via RPC.
  • mix An IDE for contract and user interface development, testing and deployment to the blockchain.
  • solc The solidity command line compiler
  • lllc The LLL command-line compiler.
