    longDescription= ''
      Bitcoin is a free open source peer-to-peer electronic cash system that is
      completely decentralized, without the need for a central server or trusted
      parties. Users hold the crypto keys to their own money and transact directly
      with each other, with the help of a P2P network to check for double-spending.

      Bitcoin XT is an implementation of a Bitcoin full node, based upon the
      source code of Bitcoin Core. It is built by taking the latest stable
      Core release, applying a series of patches, and then doing deterministic
      builds so anyone can check the downloads correspond to the source code.
