Fides: Secure and Scalable Asynchronous DAG Consensus via Trusted Components
Summary: Fides uses TEEs to build an asynchronous DAG-BFT protocol with linear-cost one-step reliable broadcast, reducing inter-vertex references from 2f+1 to f+1. New commit theory and T-RoundCert/T-Coin achieve minimal four-round latency with strong scalability. (summarized by gpt-5.6-luna on Aug 28 2026)
