Module engine 

Simplex BFT consensus engine.

This module provides the main engine that orchestrates the Simplex BFT consensus protocol for the Guts decentralized code collaboration platform.

Architecture

The engine integrates with commonware-consensus’s Simplex implementation to provide Byzantine fault-tolerant consensus. The key components are:

• Application Actor: Handles block proposal and verification
• Marshal Actor: Manages block storage and synchronization
• Buffer Engine: Buffers broadcast messages for efficient delivery
• Consensus Engine: Core BFT voting logic (Batcher, Voter, Resolver)

Usage

The engine requires P2P channels for:

• pending: Pending consensus votes
• recovered: Recovered messages after reconnection
• resolver: Fetching missing certificates
• broadcast: Block broadcast messages
• marshal: Block sync messages
