JoyStream rewards seeders for providing bandwidth with micropayments, and this leads to much higher download speeds on all content.
It was discussed here before, but now downloads are available (Win, Lin, OS X, on x64) and runs on testnet.
I haven’t tested it yet, and I don’t think I will (seems like a race to the bottom - you can seed something until someone else downloads and starts doing the same).
I find it hilarious how they say “earn BTC if you have some rare content”. How the hell can it be rare after you’ve seeded it to the world?
The list of current torrents is listed here (https://joystream.co/TorrentList/) - mostly Linux ISOs - but I doubt it will work like that on mainnet because the vendor would probably bet itself in trouble that way.
