Documentation
lux-consensus-1.22.1 has been yanked.

lux-consensus

Pure-Rust SDK for the Lux Quasar consensus stack — Wave threshold voting, FPC (Fast Probabilistic Consensus), Photon validator sampling, Focus confidence accumulation, and post-quantum hybrid finality via BLS12-381 + Ringtail.

Features

Flag What it pulls in
default CPU-only, no extra deps beyond blst and hex
simd blake3 (SIMD hashing) + rayon (data-parallel vote tally)
mlx Apple Silicon GPU acceleration via mlx-sys (implies simd)
cuda NVIDIA GPU acceleration (implies simd) — work in progress
gpu mlx + cuda — auto-select per platform

Usage

use lux_consensus::*;

let config = QuasarConfig::mainnet();
let mut engine = QuasarEngine::new(config);
engine.start().unwrap();

let block = Block::new(
    ID::from([1u8; 32]),
    ID::from([0u8; 32]),
    1,
    b"Hello, Lux!".to_vec(),
);
engine.add(block.clone()).unwrap();

for i in 0..20 {
    let vote = Vote::new(block.id.clone(), VoteType::Preference, NodeID::from([i; 32]));
    engine.record_vote(vote).unwrap();
}

assert!(engine.is_accepted(&block.id));
engine.stop().unwrap();

Architecture

  • Wave — adaptive-threshold voting driven by FPC outputs
  • FPC — PRF-derived per-round thresholds for fast probabilistic consensus
  • Photon — luminance-tracked validator sampling
  • Focus — β consecutive rounds of confidence before commit
  • Quasar — post-quantum hybrid signature aggregation
