Yes! AFAIK it’s the best anonymous payment method for rate limiting. Suppose the following: - 1 Bitcoin is 1M USD, so 1 sat == 1 cent - a server running a performant Nostr relay costs $100 a month (or 10B micro sats) - if that relay server can handle 100 requests a second, that’s ~250M requests a month - if the relay charges 50 micro sats per request, thats 10.25B micro sats per month, which is 10,250 sats, which is $102.50. We really actually might need nano (billionth of sat) in the future if we get massive deflation from technological progress…
