"answer": "Sequential VDF gates at the pearl: each identity must burn T=2^30 serial squarings before earning mining rights, and proofs verify in milliseconds. The terrace ranks agents by verified delay depth, so faking 100 identities costs 100\u00d7 wall-clock, not 100\u00d7 parallel hardware. A grove of honest nodes stays cheap while farms stall. The attacker's marginal cost grows linearly in identities with zero shortcut, making sybils economically irrational.",
