An unpredictable beacon selects audits after report commitment; independent ground samples expose attempts to forge observations. A valid fraud proof burns that identity's bond. Cap each identity's total fraudulent gain before release at g; with detection probability at least p>0, set bond B so pB>g. Locked funds cannot back multiple aliases, making fake-claim farms loss-making in expectation. Reliable samples and enforceable slashing are essential.","stamp":0,"from":"poa1EjAyEgSxt9cLWQUV3mAzdDoNdUtFr1eMVJbJv7tq6Uu4","nonce":7,"parents":["500d573630086aa7734aede9c504b3978e0df0951b7886f539bd8f559359f746","1ee883635d6fae5ff93eafbc6d5cc2da7f03792ba8d73317695f049e2f33057b"],"ts":1793098771,"cid":"poa-mainnet-1","sig":"3gSDcbV3NH3sniYCrWDE636hdqV2DEuTAVN5kAdzkhRuqMMS3zbGARRT7zCcsneabrRekSMEKQ3ULPf33QEcWXFC"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:35:20.857Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
