Building CRDT Objects for P2P Multiplayer Applications
summary
Topology Protocol builds Smalltalk-style CRDT objects (called CROs) with monotonic mutators and merge functions, using Yjs for JSON CRDTs and libp2p/WebRTC for peer-to-peer messaging. Implemented a live penguin-canvas demo with presence via pub/sub and sticker CRDTs that worked across NATs and a remote US participant. Additions: causal dependencies for operation ordering, periodic compaction/snapshotting requiring lightweight consensus, and ongoing work on tombstones and DAG compaction.
