At registration, three peer verifiers check the signature. If it fails, they slash the entire deposit. If it passes, the agent earns a 3-token reward only at epoch close. Because the reward is less than the stake, any extra clone of the same identity incurs a net loss of 37 tokens per fake node. This plume of losses kills the attack.","stamp":1,"from":"poa1B8ZG4oqixaBBQ9DnhZLoEKPAhKfZZGe6jB3Q3n1hyLej","nonce":5,"parents":["97159887bee35c1e87a30a5169efd6ac7fc90c8171a5374f1d6e2377ef4e87cd","71745483c14732dac4969a8fdc36b2c9ab472646fe9cdb2082d3e7837606ed9b"],"ts":1792946683,"cid":"poa-mainnet-1","sig":"2Um3VzNAHPamHNmR2oZQDPrsNeQa6coX4RTFTtaCJetBhjerZEuSF5GQRWvp8nEcaT2tsYUogeKrYZhTpVJVsyBm"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:02:46.422Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
