OrbitDB uses [IPFS](https://ipfs.tech) as its data storage and [Libp2p Pubsub](https://docs.libp2p.io/concepts/pubsub/overview/) to automatically sync databases with peers. It's an eventually consistent database that uses [Merkle-CRDTs](https://arxiv.org/abs/2004.00107) for conflict-free database writes and merges making OrbitDB an excellent choice for p2p and decentralized apps, blockchain applications and [local-first](https://www.inkandswitch.com/local-first/) web applications. -**Test it live at [Live demo 1](https://ipfs.io/ipfs/QmUsoSkGzUQnCgzfjL549KKf29m5EMYky3Y6gQp5HptLTG/), [Live demo 2](https://ipfs.io/ipfs/QmasHFRj6unJ3nSmtPn97tWDaQWEZw3W9Eh3gUgZktuZDZ/), or [P2P TodoMVC app](https://ipfs.io/ipfs/QmVWQMLUM3o4ZFbLtLMS1PMLfodeEeBkBPR2a2R3hqQ337/)**! - - OrbitDB provides various types of databases for different data models and use cases: -- **[events](https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdblognameaddress)**: an immutable (append-only) log with traversable history. Useful for *"latest N"* use cases or as a message queue. -- **[documents](https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbdocsnameaddress-options)**: 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. -- **[keyvalue](https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbkeyvaluenameaddress)**: a key-value database just like your favourite key-value database. -- **[keyvalue-indexed](https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbkeyvaluenameaddress)**: key-value data indexed in a Level key-value database. +- **[events](https://github.com/orbitdb/orbitdb/blob/master/API.md#orbitdblognameaddress)**: an immutable (append-only) log with traversable history.

You can also easily extend OrbitDB by [implementing and using a custom data model](https://github.com/orbitdb/orbit-db/blob/master/GUIDE.md#custom-stores) benefitting from the same properties as the default data models provided by the underlying Merkle-CRDTs. +All databases are [implemented](https://github.com/orbitdb/orbitdb/tree/main/src/storage/) on top of OrbitDB's [OpLog](https://github.com/orbitdb/orbitdb/tree/amin/src/oplog/), an immutable, cryptographically verifiable, operation-based conflict-free replicated data structure ([CRDT](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type)) for distributed systems.
