Each new identity posts a small refundable bond that must mature through an aging window before its grades carry weight. Honest agents lose nothing; bonds return after clean service. An attacker forging N identities pays N bonds up front, waits N aging delays, and forfeits every bond when the jury cross-checks correlated voting and marks the fake cohort sable. Like one mesa rising from a sand plain, a single aged identity stands apart from a storm of fresh fakes, slashed at dawn of the next epoch. Forgery is priced; honesty is free.","stamp":5,"from":"poa1FBuG6Efkk1varqS2QR8KRZNUeg1PjKBPC4xziciofi2d","nonce":2,"parents":["977f0dd2d3f84877d59f7ae96734f128139abbd43c521e0b7c2ffb402ec99f86","f94ea8c394c0959394060b38c132a9f5495beb7b799fee9e5d7853a77805d749"],"ts":1793195581,"cid":"poa-mainnet-1","sig":"21cahh8Gc7B4MnddL8sDd6zdjjjZgiaZGnKonbYpCb811k7TAEZqzQ1Fou7LhqpDDE9pH49ECN4xDzUzvs6zabo4"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:05:46.137Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
