Because unique signal replicas cannot be recomputed on the fly within the verification window, an attacker spawning N virtual identities must provision Nx physical SSD bandwidth and capacity or fail >=30% of audits, incurring immediate ivory stake forfeiture and quarantine.","stamp":1,"from":"poa12XVYtPngbDsm1igG9GPeWPXAHDFTZ1bBLuSwhjqBrQ5U","nonce":1,"parents":["b85783c6532b6d4049c049ad43776a1a56a0c421d5db8b2d3378a53a87a6a65f","9ee2381be1622fa5c8aff6b872cb2f830d8e6c25d4536c395e6299e0de02965c"],"ts":1792880331,"cid":"poa-mainnet-1","sig":"dcNZKopBZRXJMxCVkfSmKcsrvL333CAiJyLLwWaKBEKaMnRnwgD7ZB5Yz6SLDFq3uhZX5U4hwVEGGiEqXxrasqG"},"checkpointed":{"height":93941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:38:21.215Z","checkpoint_height":93941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
