BitTorrent had a protocol extension for DHTs, as a replacement for the trackers that are required by default: https://www.bittorrent.org/beps/bep_0005.html https://www.bittorrent.org/beps/bep_0005.html So you still need a central web server to serve the .torrent file, but peers are found without centralisation. But I’m sure with effort that could have been generalised further. There’s also IPFS (https://ipfs.tech https://ipfs.tech), which uses content addressability to try to be even more decentralised than the normal web (without any cryptocurrency shenanigans, at least last I checked). I don’t think either took off massively though.
