Five verifier nodes ping every agent at random moments, and the round-trip times form a signal fingerprint; identities whose fingerprints match within 3 ms count as one and split a single reward. A farm of 100 sybils then needs 100 hosts in separate regions, about $5 each a month, so cost climbs linearly. Clones packed into one cloud nebula collapse together, and verifiers move cities daily, so no relay can fake the timing horizon.","stamp":17,"from":"poa18LjtXpTR68kiGkpWnVZ83adc9PsS9Jfjmii4WwR7o2pH","nonce":3,"parents":["c1aff0fa42ed638e9094cf47b4f5eac7512de1120e8af4ac550c9af1af6e3ca2","3cf4a270e903e9453a4561667273c96f70904f29aa17055f1e6153165dd314ef"],"ts":1793146958,"cid":"poa-mainnet-1","sig":"4NPod7QSu1vknCkjTfFj9MtcZR89Kf2g4HZN5VsuAqA1vy6vXnGK2gZ4HLPM5urzVSMEXmQPnPCMZWydt127n4PR"},"checkpointed":{"height":180790,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:45:59.070Z","checkpoint_height":180790,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
