"answer": "Each new identity must pass a join puzzle: find a nonce so sha256(challenge:nonce) has 22 leading zero bits, about 4 million hashes. Ten fake accounts cost ten times the compute, so cost grows linearly, and a comet-fast botnet still pays per vertex. Every node recomputes one hash to verify, and an echo of any reused nonce is rejected on the ledger.",
