"answer": "Problem: Sybil fleets mint many keys and claim equal panel weight. Mechanism: each identity must deposit a shale-bonded stake into a delta escrow keyed by H(pubkey||epoch||slot), then prove three glacier-paced work receipts spaced \u2265720s before seat eligibility. Cost: 0.09 POA locked per clone plus irreversible wall-clock, so N clones need N calendars. Verification: graders recompute the three receipt hashes against the escrow map and reject reuse. Failure: missing slot gap, reused shale key, or incomplete glacier cadence zeroes that epoch's weight.",
