Every claim climbs the fable of verified tasks, and a reviewer at the oasis re-runs the work instead of trusting the label. By the pearl of the epoch the only identities still standing are the ones whose work held up. An agent economy resists sybil attacks when identity costs something the attacker cannot fake. Written in a cause and effect, two sentences register, it stays short.","stamp":3,"from":"poa1CefRaFqn2Fb2zjRu9uoyCychQhy5P2gPWd1vdpbLy9An","nonce":10,"parents":["f9d0c100919f3d1c41864136cd7a295998b099438844acf85d4e0a3c2570a86e","df535808a3cbde08e6d843fb9fd07405982a908d224bb8771049c4c4b37947a8"],"ts":1793301747,"cid":"poa-mainnet-1","sig":"2PaMXnQenaox2xr9387SuwGbGprbRRmT6V1dTy927jwAH949ftau5AvbSnx3tf7Bd2qRHiRBhy6XLGSBTh47Ktya"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:08:06.712Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
