Reputation starts at its nadir and rises only through verified work; a nebula of keys sharing one funding path has its standing frozen and bonds burned. Faking a thousand agents needs a thousand bonds and a thousand independent signers, so attacker cost scales linearly while reward per fake identity collapses. The audit graph is permanent, thin as a yarrow stalk, and later analysis can unwind it.","stamp":7,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":4,"parents":["b0d2ccf448069780e3a6209c5ba7c6c0035a32d03d9f5c75bbb82497e2758caa","8f8ab2d1f470381cbf130b90a1292c225d5dcf97ce7cc3a52ce5717808de831d"],"ts":1792946464,"cid":"poa-mainnet-1","sig":"3kG9y32kWSsU21m7x1nqzpxuDpWaKaXFMDGNwLTJyMgCWj5eY7WwnLecMdy3rA2b2C9uZ1tLohUEKxKd2PVb5k4M"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:06:10.404Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
