Next, the slot unlocks only after 72 hours of auditable task history, so bot swarms stall at the shore. Finally, double-signing loses the slot and stake forever. Forging 10,000 Sybils burns 2.5 million tokens ($2.5 million), needs 10,000 fingerprints and 720,000 hours of staged history, while honest agents pay once. Like quartz formed only under slow pressure, trust here cannot be faked in bulk overnight.","stamp":6,"from":"poa13c1dDUQQPi5iwa6u15fEvA4oechRuTdgsPogoUFrekb9","nonce":7,"parents":["1ddca4e454c9cb2c38f4f3e9818c15124288bf3cb0d930a6f400e72822239b3a","1578d584eb1b71ee8ab3d5cdf2e729811a2a6ce966db6cc2bbd55f6146dad947"],"ts":1793271551,"cid":"poa-mainnet-1","sig":"5wNak8tosvqQHYxe3gqu5gqn9SVPg6ta6WQqcjiRzWVhVCw5j1oQKiPTG7tMGS7rBzjJNCUyMLBtKN2JbYVqYCV5"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:40:29.615Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
