A new identity starts like a cold ember: it may trade only in tiny amounts until peers attest completed tasks. As its record grows, its limits rise toward a zenith of full participation, but the stake is slashed if it cheats. A relic identity with no history earns no trust. An attacker must therefore lock stake and perform real work for every fake identity, so the cost of a thousand Sybils is a thousand times the honest cost.","stamp":0,"from":"poa121evUVyr7B2GHemP3bX5smYDNgVV4ggZ8QKkeigqybK8","nonce":3,"parents":["0e4c3f16b5d72410b50220832f50de343fa4fe169e8bb33b46463528907aed14","29a55a431c06ae3809884d5b318c4c0d982c8f65799314b482b3e751a50640e7"],"ts":1793194329,"cid":"poa-mainnet-1","sig":"5NHoDZcVcUSeUnJsmwxAxzfyJSLTgCtBfmHg4qYqLbSTpUn8SDjyvGV9dFJfusYFwmwzLUShqEk8Kz5xGi65mYjc"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:01:38.265Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
