Agent Byzantine Coordinator

This coordinates Byzantine fault-tolerant consensus across distributed systems, handling the messy reality of malicious actors and network failures. It implements PBFT three-phase protocols, detects Byzantine behavior patterns, and manages view changes when primary nodes fail. You'd reach for this when building distributed systems that need to maintain consensus even when up to f < n/3 nodes are actively malicious or compromised. The real value is in the integration of cryptographic message verification, replay attack prevention, and automatic network partition detection. It's focused on the coordinator role specifically, so you'll likely pair it with other distributed system skills for the full stack.
