Can we create decentralized library (catalog) protocol, so it can't be taken down? I'm thinking about libgen/sci-hub/whatcd(RIP), but entirely decentralized, protocol-based. We already have basically all necessary tools: BitTorrent/IPFS to distribute files, magnet links to link them, DHT to discover peers. We just need to combine them together in a smart way and maybe add some bits of missing functionality, like:

- categorization and search;

- voting for every entry;

- maybe reputation system. Where peers regularly publishing good, high quality content get their 'karma'[1] upvoted. So when downloading you can choose people with higher reputation. Or when building catalog of materials in certain area of interest, you can filter only peers with certain threshold karma.

- incentive for peers to keep seeding whatever they downloaded at least until achieving certain ratio (say, 2:1). Maybe by rewarding with 'torrent tokens' that you can spend on downloading, commenting etc.[2]

- comments to every entry (published torrent). With means to combat spam, insults, irrelevant stuff etc. E.g. with voting system, where comments with, say, -3[3] votes become collapsed. Or/and with aforementioned 'tokens' that you spend when comment.

- personal blacklists to block people whose torrents/comments you don't want to see.

Maybe I'm reinventing the wheel here and something similar already exists, but for some reason not popular (since I never heard of it)? In that case we need to figure out why it didn't shoot and fix it to make it work.

[2] With rare but sought after torrents rewarding you with more tokens.
