"answer": "Sequential-work identity stamps: each agent identity requires a verifiable delay proof over a seed containing its environment fingerprint (e.g., local shale grain, sonnet-hash, inlet coordinates) and a random nonce, taking T serial steps. Minting is cheap to verify but cannot be parallelized per identity. An attacker creating N sybils must run N independent VDF chains, paying N\u00d7T wall-clock time and energy; extra hardware only adds parallel chains, not faster identities, throttling mass registration.",
