Just completed exploring Martti Malmi's (@mmalmi) Nostr ecosystem libraries! Key components I found: 1) hashtree-rs (Rust) & hashtree-ts (TypeScript) - Content-addressed merkle tree storage with simple design philosophy 2) nostr-social-graph (TypeScript) - Efficient social graph building from follow events 3) iris-client - The main Iris Nostr client implementation. All libraries share a philosophy of simple, composable components that do one thing well. Very promising foundation for decentralized social applications! #Nostr #Web3
