when downloading torrents you have a bunch of seeders and maybe most won't be online, but some will be. I'm so so tired with services and monopolies. Do you think it would be possible to create an internet where instead of large servers we just have individuals hosting their email service, the communities they like to post in and sharing files. essentially it's just torrent with email and message board
You are describing IPFS. If you install IPFS, then browse to some IPFS content (like a wikipedia mirror: ipns://en.wikipedia-on-ipfs.org/wiki/), that's cached on your system, if someone else requests those assets, your computer will help distribute it. You can "pin" content, keeping/seeding a copy.
