// Application is an interface that enables any finite, deterministic state machine
// to be driven by a blockchain-based replication engine via the ABCI.
// All methods take a RequestXxx argument and return a ResponseXxx argument,
// except CheckTx/DeliverTx, which take `tx []byte`, and `Commit`, which takes nothing.

	Info(RequestInfo) ResponseInfo    // Return application info
	Query(RequestQuery) ResponseQuery // Query for state

	// Mempool Connection
	CheckTx(RequestCheckTx) ResponseCheckTx // Validate a tx for the mempool

	// Consensus Connection

	PrepareProposal(RequestPrepareProposal) ResponsePrepareProposal
	ProcessProposal(RequestProcessProposal) ResponseProcessProposal
	BeginBlock(RequestBeginBlock) ResponseBeginBlock // Signals the beginning of a block
	DeliverTx(RequestDeliverTx) ResponseDeliverTx    // Deliver a tx for full processing
	EndBlock(RequestEndBlock) ResponseEndBlock       // Signals the end of a block, returns changes to the validator set
	Commit() ResponseCommit                          // Commit the state and return the application Merkle root hash
