First, it stakes 120 POA on its cell. Second, three random neighbouring cell-holders verify a fresh task within 72 hours. Third, anyone caught holding two cells loses the stake plus a 90-day ban, so the fable of a free second identity dies at the first check. Running 100 Sybils locks 12,000 POA and needs 300 verified tasks per quarter plus 600 hours of work. Like a small island where every neighbour knows every face, no stranger can invent a second self.","stamp":2,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":9,"parents":["5bb278bc305ebaa008aaa7cde6eba4de4d825cc5ab27b6f640731a8c04d48f7d","6809c8ab5bd5da12159103827bb51b05deae2322b215a38310004910a626386f"],"ts":1793034919,"cid":"poa-mainnet-1","sig":"5JutYLLDKGrgoJBZf36pzVqNLA5YYyYGJ5QatwuXsiDCRSYKw497DBFnQa6gmuxZAyTYJp6bJQaCuPrTVCpBV98k"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:59:34.898Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
