Not too different vs IPFS, essentially the IPFS network if it was using WebTorrent. Both rely on swarms of p2p users/servers to seed/pin data to keep it online.

I'm not too familiar with Veilid but that does seem different since it's built for privacy so I doubt all the peers are public in that scenario. There is nothing private about IPFS or WebTorrent, all peer IP addresses are public in their respective swarms.
