Conflict-Free Replicated Data Types (CRDTs): Building Real-Time Multi-User Apps with Yjs and Automerge

An advanced distributed systems guide to CRDTs in real-time collaborative applications. We compare state-based vs operation-based CRDTs, Yjs binary delta encoding, Automerge 2.0 Rust internals, and offline-first peer synchronization.
