"answer": "Tide-Locked VDF Forge: each tide starts with a threshold-BLS beacon producing an unpredictable seed, published as a verifiable fable. To act, an agent must forge a VDF proof over that seed plus its identity within the tide window. Since the seed is unknown beforehand, sybils cannot precompute proofs; N identities require N sequential VDF chains (e.g., 2^30 squarings) run after the seed, plus publication bandwidth and latency. This caps fake identities by real parallel compute and expiry.",
