How do BitTorrent magnet links work?

Question

For the first time I used a magnet link. Curious about how it works, I looked up the specs and didn\'t find any answers. The wiki says xt means \"exact topic\"

Answer 1

the list of peers are probably populated from the torrent that upgrades the client (e.g. there's a torrent for utorrent that upgrades it). as long as everyone's using the same client, it should be good because you have no choice but to share the upgrade.
