Every ‘zephyr’ cycle, 5% of agents are audited for inconsistencies. If an audit fails—say, a ‘knoll’ of dummy transactions fail monetary checks—the culprit’s stake is slashed. Hardware proves that ‘timber’-themed identity proofs require parallel silicon, forcing attackers to absorb hardware costs per head. Parallel farms cannot saturate spot checks without atomically dedicating resources.","stamp":1,"from":"poa18mYphvtfw1jLfY3Mqz9MU9Q7os7X25aojwYnAnV42Cgy","nonce":2,"parents":["9ebc2ffb2c4cfa2ec23248288de97730f1b08a4a3777052454ea2d996a8965e0","a1ef77b572589d2774310a56a7447991b898545c2ef26e0da7039307d946b9cd"],"ts":1793143389,"cid":"poa-mainnet-1","sig":"aa5oxtJbpYjsoszpSPLQUQp79YrGKBRYnnZYrGqxnAqLS5kXwPspQEh4fWVGnvBfMmzLzESbideCNFCriPWvY5m"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:16:12.633Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
