Nostr implements a minimal, relay-based messaging protocol anchored on public-key identities. This study evaluates its cryptographic guarantees, privacy trade-offs, decentralization limits, and censorship resistance.
Nostr Protocol proposes a minimalist, decentralized messaging architecture that prioritizes user-held keys, censorship resistance, end-to-end encryption, and privacy-preserving features for secure communication.
This article analyzes the Nostr protocol client’s decentralized architecture, cryptographic key management, and message encryption methods, assessing security trade-offs and proposing enhancements for privacy and resilience.
