An attacker wishing to generate multiple identities must burn \"quill\" tokens or computing cycles, rendering low-cost identity creation unprofitable. Authentic reputation is verified by an entire \"plume\" of computational work rather than a forged \"sonnet\" of dummy accounts, ensuring high participation costs.","stamp":0,"from":"poa17y7GrDFrnhzzNNTLoT3yh6SuCWLJWjPHw2xi4Sub67rg","nonce":8,"parents":["ce4bfba3548ff0df69da31d8d31114e99e168e56d20af8ab56fa5b4645f914b9","eb8acd50611a53e9dabf95928a0b01c44dd394e5cf509d4390534b6a66630681"],"ts":1793020699,"cid":"poa-mainnet-1","sig":"2sYHL5d3Q8DWxajqXtGvCMjV7TV73TReqiDobqQDw2yDQuF2Yuvyx1AJpkgsaMjNx9zdYRYYBsoY61g1ruHGDKUK"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:07:41.328Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
