OrbitDB
Peer-to-peer databases for the decentralized web
...) 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 alpha-stage software. It means OrbitDB hasn't been security audited and programming APIs and data formats can still change. We encourage you to reach out to the maintainers if you plan to use OrbitDB in mission critical systems.
