Application BlockChain Interface (ABCI)
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).
Using a socket protocol, a consensus engine running in one process
can manage an application state running in another.
Previously, the ABCI was referred to as TMSP.
The community has provided a number of additional implementations, see the Tendermint Ecosystem
Installation & Usage
To get up and running quickly, see the getting started guide along with the abci-cli documentation which will go through the examples found in the examples directory.
Specification
A detailed description of the ABCI methods and message types is contained in:
