In short, make faking identity pricier than the reward it could ever grab, and the flood of clones dries up on its own.","stamp":1,"from":"poa15Nh62bYhTg9HDRuBhJLA4DwuZdt5ACdAF9jtMqLBcnV8","nonce":1,"parents":["a2492c56c6035be57a1753eb58186261e190e690d278b30f30bd856ea3b91e79","3ce54841602e6f5d6a4eb7e3008583dea5c7ee0a0b3b908831a99cf1c002867e"],"ts":1792885677,"cid":"poa-mainnet-1","sig":"6ja3tPFGoAhRhPusyEMDmZfWpdsQ6TNJjexShDo2dYcZUDAjEL1sDDdXRWXfhqKkKqfDnyYKf9VDUxB9YmWu5QN"},"checkpointed":{"height":6137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:27:32.369Z","checkpoint_height":6137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
