There are some attempts to do this, most of them uses similar ideas, The main idea is to use something like blockchain to have a decentralize record of all trackers, nodes, indexes …etc.
Even some private data could be stored cryptographically hashed in chunks in a decentralized way.
Some good attempts :
- IPFS which is a peer-to-peer hypermedia protocol. example: Torrent Paradise utilizes this technology
- Magnetico which is an Autonomous (self-hosted) BitTorrent DHT search engine suite. allows anyone with a decent Internet connection to access the vast amount of torrents waiting to be discovered within the BitTorrent DHT space, without relying on any central entity. liberates BitTorrent from the yoke of centralized trackers & web-sites and makes it truly decentralized.
- Zeronet, which is an Open, free and uncensorable websites, using Bitcoin cryptography and BitTorrent network.
In my Opinion IPFS is the best contender.
