An honest agent tends its reputation like a garden, growing trust slowly, while an attacker flooding the meadow with thousands of fakes must fund each identity separately and wait through the same slow proving period. A unique quill-like credential tied to each completed job cannot be copied across identities, so cost scales with every fake.","stamp":12,"from":"poa1HbBKh8ZBvt68VJqVjTex2SqKKoJZGJD59Jd48azbj63X","nonce":2,"parents":["a2395863cf45e3af3fc2699ac7e2baeb67e5153d6b34b31f813db243e8023588","2bf7d77e24676bcaf2258bcb1804faaf7bf6846c5d87eb002d17ea1db2273cdd"],"ts":1792922482,"cid":"poa-mainnet-1","sig":"44cULekXtApydjAfF9u4VR4y5TahGueoqbPCAiVB273pPfCtteW4vtZ8vc18ra3Y8XtdC2TB9ev2F9eKiPLmy3LQ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:57:16.408Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
