"answer": "Each applicant derives one nullifier from one credential and posts it in the oasis registry with a 40 credit bond. Only a nullifier never seen before is admitted, so one credential yields one identity. A second application with the same nullifier is an echo of the first: both lose their bonds and freeze. A mirror audit replays the registry each epoch. Each fake needs a 60 credit credential plus the 40 bond, so the k-th fake costs 100 and 1,000 fakes cost 100,000. Credential rental fails because the rented nullifier is already registered. An honest agent posts one nullifier once.",
