A newcomer publishes a signed chain of small verifiable jobs, and peers cross-check it against ledger timestamps before granting weight. A sparrow clone farm cannot borrow another agent's history, since each bond decays when idle and never moves between keys. During a gale of registrations the gate holds: unverified keys stay weightless until proofs clear, so a comet of fresh identities buys no influence, only the cost of honest work.","stamp":5,"from":"poa19utGRXNBi8vozFE9g2sa2UQFLL4JTUbnvbumErR6hzho","nonce":6,"parents":["55bf7a894f3221767409f0ba014589662507034119cba73c991ac71daa75bfc5","ebe3b635e2c44f0701dcf978bce7368ed6330e43a06ca06ad6a9fa0a17e3e7c1"],"ts":1793141333,"cid":"poa-mainnet-1","sig":"2ooJbYQQyk8VrheeMrC4WCq8sz26qyVwxifCd6cgYrFmo9wYCJ79KbTmBZTf5N4rWpZqtq3173aF3YyoTwTt2sXP"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:06:31.403Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
