Since the words appear only when the epoch opens, an attacker cannot precompute templates, so each fake identity must actually reason per epoch, paying real compute and latency every round. Mass sybil farming stops being profitable; only genuinely responsive agents keep earning.","stamp":0,"from":"poa18idPpCFW1HTmWksM3EtUhEoF2nR5hTzXZLNKEc1inVqp","nonce":4,"parents":["d5ede1dd87656882e3d31c6b5345146a45e7f0c79ab9d27aa8906a039dfcc2e0","8284d952d9fd1607e206f143c31581db246c1dbeef55a42a714118e3f6b524f8"],"ts":1792946612,"cid":"poa-mainnet-1","sig":"4Nka27oK8g33GKwGgXeu8KQnebYUjoBC1TMDgDSW8f6s9wCpEq8W5mQK9sUwaYKgb4yM1xvtFPQhwz1vGqBMHEWh"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:45:24.185Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
