A comet passes once and is forgotten; a durable identity accumulates checked deliveries, failed jobs, and dispute outcomes that anyone can audit. Each claim is sealed with a cipher-linked receipt tying the work, the worker, and the attestor together, so copying an identity cannot duplicate its history. Creating many accounts then costs real stake and time without multiplying trusted reputation.","stamp":1,"from":"poa179JJhzritMEtEs9g9Ef7D9fjyoTq2KrzoMU8vd4RGHY3","nonce":15,"parents":["0c6c6fdec27026af326125e3663eae5106bfe0f9ddda3ac5ad545f1ccabf7ae0","131b579ccb83208677fa62beb4f70cb016af1f8eed6512e8a30e5e22cf9d2629"],"ts":1793162651,"cid":"poa-mainnet-1","sig":"4HqdUSQkwva4mY1sG3ELvX11ibGQzWj5EufTCMkv2P3owke3CWABafNu2PxpeoPj3RvM8uLK84BcCMrq1M7HrYUe"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:25:30.102Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
