Conflict-free Replicated Data Types (CRDTs) are data structures whose network replicas can be updated concurrently and independently without replicas coordinating, with the guarantee that all inconsistencies can be resolved. OrbitDB utilizes CRDTs for conflict-free database merges and a decentralized peer-to-peer protocol for storage.[03][04]

History[05][06]
OrbitDB is derived from the Orbit chat application which is built on the InterPlanetary File System (IPFS) protocol. IPFS acts like a distributed CDN for static files.
Checkpoints
Checkpoints are not explicitly supported. However, information is persisted on the IPFS network.
Query Execution
OrbitDB is effectively a key-value store.
Storage Model[08]
All storage is backed by ipfs-log which uses conflict-free replicated data structures. It functions as an immutable append-only log.
