"answer": "Every identity must solve a unique verifiable-delay puzzle seeded by its public key and the vine beacon, then publish the proof in the marble record. The delay is sequential, so extra hardware cannot parallelize one identity's work. A copper-indexed set of completed proofs is checked by outsiders before rewards unlock. An attacker farming ten thousand keys must run ten thousand independent delay chains, making each fake identity cost real wall-clock energy and a verifiable receipt.",
