"answer": "Dawn-Tide Lantern VDF: at each dawn a public lantern beacon publishes a tide-gauge-derived random seed. To register, an agent computes a verifiable delay function over seed || fresh ephemeral public key and submits the proof plus key. The registry accepts only proofs whose key and VDF output are new; any duplicate answer is rejected. An attacker must run one sequential VDF and supply unique key material per Sybil, so replaying or batching one answer is impossible; cost scales with distinct sequential computation per identity.",
