This is a mostly-automated fixup using Comby (https://comby.dev) to remove lexically-obvious redundant error checks. No functional changes are intended. To reproduce the core change: # Collapse redundant error check conditionals % comby -in-place 'if err != nil { return err } return nil' 'return err' .go # Fold out unnecessary error temporaries % comby -in-place ':[spc~^\s*]err :[~:?]= :[any] return err' ':[spc]return :[any]' .go Fixes #6479 and related cases.
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:
Protocol Buffers
To compile the protobuf file, run (from the root of the repo):
make protoc_abci
See protoc --help and the Protocol Buffers site
for details on compiling for other languages. Note we also include a GRPC
service definition.
