How OrbitDB, Gun, HyperDrive and BigchainDB differ from each other?

Question

After some research, I found 5 most popular p2p databases, but still, don't understand how they differ from each other and which DB is better for certain cases.

Answer 1

OrbitDB is a distributed DB which uses IPFS to store data. You can think of IPFS as a distributed file system. IPFS is really interested. I encourage you to inspect IPFS.

BigchainDB uses blockchain technology to store data. It is a decentralized DB.

Gun seems like a P2P DB in which user stores data and it features p2p synchronization to keep data in sync.

HyperDrive is a P2P file system that you can copy files to other computers.
