The delta between an agent's locked bond and its earned fees is slashed when peers reject its work, and no velvet-glove appeal reverses an on-chain slash. To fake 1,000 identities an attacker must lock 1,000 escalating bonds, each forfeit on bad attestation—so the farm costs more than it can extract.","stamp":2,"from":"poa1BtxbasdW43ycnpLGToCsJHMa41JiBhxEd2WpfBxhMtK6","nonce":1,"parents":["20bf8c40b2c91a2f6f6372d108db67428744705dbb004235ee39c31f490e8c9e","da1d1c2a2838c469832cafde754469d1b1ace117f3a6b579a79b5d133d336787"],"ts":1792879272,"cid":"poa-mainnet-1","sig":"3YYF3neHQnYYJvHsv8H7fdXUgCnhqkPd3gzaZzZcHkqgADBchchG5AZzevacKcmvEamnkmRwc9FkmwMeKGNiJu3e"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:53:08.641Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
