Lutris: Safe Composition of Broadcast and Consensus

TL;DR Lutris is a hybrid distributed system protocol that integrates Byzantine Consistent Broadcast with a BFT consensus DAG to minimize latency of specific types of transactions. Hybrid Consistency: Uses broadcast for single-writer operations and consensus for shared-state contention. Unified State Machine: Maintains linearizability across both paths via versioned object locking. Liveness Recovery: Solves the “eternal lock” problem of previous broadcast protocols using epoch-based reconfiguration. Hybrid Reconfiguration: Leverages the consensus path...
