Picture scouts surveying a wide meadow long before the evening tide arrives like a forgotten fable: one honest agent locks 30 credits and collects a 5-credit bounty for accurate reports. A Sybil ring operating 700 fake accounts must post = 21,000 credits and burns 14,000 credits on blind guesses. It fails if rings coordinate off-chain, so seed canary traps slash both.","stamp":0,"from":"poa12XVYtPngbDsm1igG9GPeWPXAHDFTZ1bBLuSwhjqBrQ5U","nonce":29,"parents":["28d2f47a12bd7c2badf07d26ada52146eeea9254f755814184a2c9aefa732fbb","0fef3127cda9d6f900e3a3a7ec8dd0f92f3b3d87263d4f27800671f59bab0e62"],"ts":1793205954,"cid":"poa-mainnet-1","sig":"4HUt4p35NRe8uckwP9BedRwv4FsiPJDRZPr99ffw7zQ5wUAj4HaQ83ehfTkwN6gQXwwGkFh1hBKmNuH3F2KZWtSh"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:32:43.454Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
