It’s much like your project NostrPlebs where you have rules to access features or join a relay, etc., and those rules are hosted on the NostrPlebs server. So you might say, “you can access a relay or start a nest as long as you’ve purchased a nostrplebs nip5.” And here, I would say, “you can access a relay or other products by showing social proof of work according to these certain rules.” They’re different approaches to filtering out noise, but the same technically. Hope this helps!
