Peer-to-Peer Databases for the Decentralized Web
OrbitDB is a serverless, distributed, peer-to-peer database. OrbitDB uses IPFS as its data storage and IPFS Pubsub to automatically sync databases with peers. It’s an eventually consistent database that uses CRDTs for conflict-free database merges making OrbitDB an excellent choice for decentralized apps (dApps), blockchain applications and offline-first web applications.
OrbitDB provides various types of databases for different data models and use cases:
- log: an immutable (append-only) log with traversable history. Useful for “latest N” use cases or as a message queue.
- feed: a mutable log with traversable history. Entries can be added and removed. Useful for “shopping cart” type of use cases, or for example as a feed of blog posts or “tweets”.
- keyvalue: a key-value database just like your favourite key-value database.
- docs: a document database to which JSON documents can be stored and indexed by a specified key. Useful for building search indices or version controlling documents and data.
- counter: Useful for counting events separate from log/feed data.
All databases are implemented on top of ipfs-log, an immutable, operation-based conflict-free replicated data structure (CRDT) for distributed systems. If none of the OrbitDB database types match your needs and/or you need case-specific functionality, you can easily implement and use a custom database store of your own.
OrbitDB is an open source, open project. Anyone can jump in and hack on it; anyone can create submodules that use it or get involved in planning future developments. That having been said, much of the work is currently funded and run by members of Haja Networks.
