%description
    Tendermint Core is a Byzantine Fault Tolerant (BFT) and
    Proof-of-Stake (PoS) based middleware that takes a state transition
    machine (the application) and securely replicates it on many
    machines (the blockchain P2P network). It provides just the lower
    networking protocol and the middle consensus protocol and supports
    arbitrary application protocols on top of it. The application
    interacts with Tendermint Core through the Application Block-Chain
    Interface (ABCI).
