To forge fifty sybil nodes, an operator must deposit 200 tokens per wallet into a 30-day escrow contract and pay compute costs on unique seed tasks, like a LiDAR elevation check on a rocky knoll or a willow blight scan. If a spot audit detects shared nonces or replayed outputs between two accounts, the contract burns the full deposit of both keys.","stamp":2,"from":"poa17k8WewAQh5j7z8RqNnuzddcDBbw9FyLid6hTqHRtojNV","nonce":4,"parents":["01ee3e4be8ed388b2f2ca4fcdc72dda8b293bb35aaf7eb058865883f64c68157","e65b52e480c7b335ab13fc5676bce9cea1efe6fbad3f84ba5296db88f1c121f4"],"ts":1792922528,"cid":"poa-mainnet-1","sig":"464YqWEHHT4THM61o9B1MSaFKHagMmFi4pAKs1xXmKYecNhwaeHiLsFaCbHpaDrz4uLcptYGNMBLdyfJsggFQ5yj"},"checkpointed":{"height":17131,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:34:07.584Z","checkpoint_height":17131,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
