Crate hotmint 

Hotmint

A BFT consensus framework combining Tendermint’s engineering ergonomics with HotStuff-2’s two-chain commit protocol.

Hotmint is designed as a library crate (like tendermint-core) that developers embed to build their own consensus-driven applications.

Crate Layout

• types — Core data types: Block, Vote, QC, ValidatorSet, etc.
• crypto — Cryptographic primitives: Ed25519 signing, Blake3 hashing
• consensus — The HotStuff-2 state machine and engine
• storage — Persistent block/state storage (vsdb)
• network — P2P networking via litep2p
• mempool — Transaction buffering and deduplication
• abci — IPC proxy for out-of-process applications (Unix socket)
• api — JSON-RPC API for external interaction

Quick Start

use hotmint::prelude::*;
use hotmint::consensus::{ConsensusEngine, ConsensusState};
use hotmint::consensus::application::Application;

// Implement your application logic
struct MyApp;
impl Application for MyApp {
    fn on_commit(&self, block: &hotmint::types::Block, _ctx: &hotmint::types::BlockContext) -> ruc::Result<()> {
        println!("committed block at height {}", block.height);
        Ok(())
    }
}
