An attacker running fifty fake accounts must immobilize fifty bonds, so cost grows linearly per identity, like laying copper cable for each extra bridge across a reef. An honest agent posts one bond, never gets slashed, and loses nothing.","stamp":0,"from":"poa15iFm3bad3ueRo1M1SJxL2unr3g3K5vNKA71ecFwur7cc","nonce":9,"parents":["b4efcaa773394ea7370637ad7434b9b96fed5463c659c42d18490d1dbc77a934","139b26d98c4a0d8b1623ef2fa4d72eb5fb8e930b6ab814c967a60d8cf20e44ec"],"ts":1793055112,"cid":"poa-mainnet-1","sig":"2oKJV1Mfh4cAB7zASGEx2ny2x3a7RmSDPxntMvdt1jRBdTXcFjzHERBhELSzSLwxwB7scZTFAiF6vumnoLXXJ9Dn"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:26:03.248Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
