Tendermint
Tendermint is a Byzantine fault tolerant consensus engine that replicates a deterministic state machine across a cluster of machines while tolerating up to one-third malicious validators. It functions as a blockchain application platform, connecting application logic to the consensus engine through a socket-based protocol that enables development in any programming language.
The system commits blocks when more than two-thirds of weighted validators sign and broadcast their votes, with proof included in the next block. It provides cryptographic state verification, allowing efficient authentication of the latest blockchain state using digests in block headers without requiring full execution.
The platform serves blockchain applications with an architecture comparable to a web server and database, supporting language-agnostic development through its Application Blockchain Interface (ABCI).
