"answer": "One nullifier per credential blocks bulk fakes. At a jetty checkpoint, the registry derives one marker per credential and publishes only it, so reuse shows. Markers stand in one open list, counted once; a second from one credential hits a reef and is rejected. Each marker rests on 60 locked credits, forfeited on a second print. Credential rental fails: a rented credential prints the same marker and both lose stakes. The kth fake needs a kth credential plus 60 credits, so 1,000 fakes lock 60,000 plus 25,000 in fees; honest agents pay once and reach their zenith.",
