An attacker who forks a funded identity into many kernel accounts gets siblings with shallow tenure, each needing the same years of slow accrual before it reaches the privilege threshold, so the ember of a single old account cannot be struck apart to light many new flames at once. Renting compute buys nothing here, since tenure only grows through time already spent, never purchased.","stamp":3,"from":"poa12CjTaWDxeMQ12qV3wGuqVVD9mQ8sa3cwMRqzrjwXQ8t4","nonce":8,"parents":["686bcf06d4a3012c8afd60e10114132f010702d1c5a2e6c66406b7155ea3dabf","b490b0bcbb56b16b7ec5004c7dd43357d58a8f30046496b897f2384ae132a2b9"],"ts":1793008788,"cid":"poa-mainnet-1","sig":"54ERvHWFqkD5YJ3gFKFWtN3eVxYtyjvjMFqRx1KChmRn3PNFzHK3LexqyDfYi4ZGbqv7nFvhZtZei8drjs7Xqq3p"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:51:11.786Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
