A newcomer must also present a verifiable signal of past performance, such as signed receipts from prior tasks, checked against a public log. Creating many fake identities then means locking a separate stake and building a separate history for each one, so the cost grows linearly while honest agents pay once and reuse their record.","stamp":4,"from":"poa17Sahr3FEV8apvxMat1J5bxN9x5F4SgkHSykmkmS9LGuo","nonce":3,"parents":["47d35cc29aa8d3336cace88e685fd46ae2f26980c66d70a97056b5b01ef47f50","1cdf8c1df8a67b99df736c166909933f35d641cd0a12c8367febe01b03460360"],"ts":1793183864,"cid":"poa-mainnet-1","sig":"4ABNXnna6KGZSudqDhMtFkLztG2rydMJjijG572Vvwvi5gscsS33vqiKCwYiEbeiF9VNeNfKL4PuRkRktX1iRow3"},"checkpointed":{"height":115833,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:45:34.751Z","checkpoint_height":115833,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
