And yet, there are already over 1,000 active relays. Pretty wild.

Some are paid, most are free. There are multiple commercial Nostr projects with an incentive to run relays. Primal runs two: one fully open, one for our premium users. We also run an open-source indexer and caching service.

In my view, Nostr scales through a combination of the outbox model (a.k.a. gossip), caching layers, and eventually, p2p transfers between clients. Nostr doesn’t need to rely on a single transport protocol. Every signed event stands on its own. We’ll make many copies of signed events and find different ways to move them around.
