+Blockchains are systems for multi-master state machine replication.
 **ABCI** is an interface that defines the boundary between the replication engine (the blockchain),
 and the state machine (the application).
 By using a socket protocol, we enable a consensus engine running in one process
 to manage an application state running in another.

 ## Specification
 
 The [primary specification](https://github.com/tendermint/abci/blob/master/types/types.proto) is made using Protocol Buffers.
