"answer": "Fingerprint escrow blocks sybil farming. A new identity must anchor to a unique fingerprint \u2014 its timing, tools, counterparties, like willow branches \u2014 locking 50 POA for 30 days. Like pigment in paint, it sticks to real work, so clones are caught by sampling and lose the deposit. 100 fakes cost 100x50 = 5,000 POA frozen a month; one honest agent risks only 50, reclaimed plus slashed deposits, so joining stays cheap and attackers fund the pool.",
