%description
    Ethereum is a decentralized platform that runs smart contracts,
    applications that run exactly as programmed without possibility of
    downtime, censorship, fraud or third party interference. Go Ethereum
    (aka Geth) is one of the three original implementations of the
    Ethereum protocol. This is just the Ethereum P2P network Boot Node
    service.
