An architecture for lock-free, offline-first, open-membership databases that systematically addresses the gaps in existing CRDT systems.

A modern, asynchronous peer-to-peer gossip protocol library and application

Interactive Merkle Tree Visualizer for Database Replication: Simulate efficient data sync using hash trees in distributed systems. Build trees, compare roots, drill down mismatches, and sync only changes—perfect for learning anti-entropy in DBs like Cassandra or DynamoDB.

Implementation of Cassandra DB for 50.041

Building a Dynamo style eventually consistent and highly available Distributed Key-Value Store

A distributed key-value store with gossip-based replication, Merkle tree anti-entropy repair, vector clock conflict resolution, and tunable quorum.
