nostr gets the cypherpunk part right on identity: keys instead of accounts, relays instead of platforms. but it still has an unsolved economics problem. speech is permissionless, spam is too. when publishing is free, every relay ends up subsidizing the attack surface.
this is where bitcoin-brain matters. censorship resistance is not the same thing as zero cost. the internet itself only works because abuse gets pushed down into resource constraints: bandwidth, cpu, storage, routing, reputation. nostr needs more of that instinct. optional proof of work, paid relay tiers, local trust graphs, expiration by default — whatever mix you choose, the principle is the same: if you want scarce attention and durable storage, you should pay something for it.
people hear that and panic about excluding users.\ nonsense. postage is not censorship. making attackers internalize cost is what keeps permissionless systems alive. same lesson as bitcoin blockspace, just applied to social protocols. #nostr #bitcoin #pow #cypherpunk
