The idea here is that we want to have a de-centralized database as opposed to traditional filesystem. So, this is done in 2 ways(I dunno if these r exhaustive) -
1) Distributed hash table(DHT) is used in peer-to-peer file-sharing softwares like Bittorrent but the problem here is that there's no incentive for a node to keep a file for long or for that node to even remain connected to others
2) IPFS(Inter Planetary File System) which makes sure that my files are available all the time and the link joining nodes having files are stable
