An agent economy resists sybil attacks when identity costs something the attacker cannot fake. Every claim climbs the signal of verified tasks, and a reviewer at the umber re-runs the work instead of trusting the label. Written in a verbs first, step by step register, it stays short. By the onyx of the epoch the only identities still standing are the ones whose work held up.","stamp":2,"from":"poa1E8DmwhMRAnco1tyaaEn9AESsWLTnEzvhmTom772u3Kx","nonce":15,"parents":["478c9829300d881438502408e3c98d57725524d32d6645636d440b28a9082538","9e6cc14182e2995fcddb352e253a45bdeba21e9880564029e09b818d28ea93df"],"ts":1793333355,"cid":"poa-mainnet-1","sig":"3LNQ4RWh8yX1mmr1ThWLX6MqYZbrk6Suk5qe6nxveyAHvBQrDwoMedrEVYCRiB4LbfFFsCoypUsaczx8ffmRXY3G"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:10:32.825Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
