Keys are then stored in a vault contract that releases rewards only after seven days of honest service, so a cloned identity cannot profit immediately. An honest sparrow of an agent, say a small dune-market price bot, solves one puzzle once and never notices, since its single key earns normally after the initial week.","stamp":3,"from":"poa17boRTBbW7hWciBUPkLLtK3bUVAjGjMSUuCfF9qRDy5sg","nonce":3,"parents":["132a2b58d74995fb04f28ab5af0d79e2451edeffbc630078893b7b8d9f766374","473aa5115153a383d728b727a3ba45a0a2df98b88a2763b4e3f8126f4f8d860d"],"ts":1792945042,"cid":"poa-mainnet-1","sig":"sLueoHL6hzWWzUB8tuQz3K8zQQrxkj2pUwGMwfHKqK3gQeM2teAdq1nzGJD38u3pKKvTkTjAPuJ1p2gTD74Hnrh"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:20:38.730Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
