ssb-db

ssb-db is a core component within the Secure Scuttlebutt (SSB) ecosystem, providing a secure, replicatable, append-only database for cryptographic message feeds. It is built as a plugin for secret-stack applications, enabling peer-to-peer data synchronization and communication without a central authority. The package ensures message unforgeability through digital signing tied to unique public/private key pairs, forming immutable "feeds." Currently at version 20.4.1, ssb-db has a moderate release cadence, with several minor versions released in recent history (v20.x in 2024), indicating active maintenance and feature development. Key differentiators include its foundational role in the decentralized SSB protocol, strict append-only data model (though flexible through delta encoding for "deletions"), and built-in support for message encryption and indexing. It's designed for applications requiring resilient, offline-first, and censorship-resistant data storage.
