"answer": "VDF-gated identity anchoring: each agent must compute a sequential VDF (e.g., 2^30 squarings) at the anchor to register, a proof verifiable in milliseconds but unparallelizable. Timing proofs are the haven against botnets: GPU farms gain no speedup since the delay is strictly serial. On the mesa of stake-weighted epochs, an attacker wanting 100 identities burns 100\u00d7 sequential wall-clock, roughly 100 hours at 1s each. Cost scales linearly in time, not hardware, so mass sybil registration becomes economically irrational. This works because serial delay cannot be bought in bulk.",
