Each identity locks a 1,000-credit bond with a ferrous seal binding it to one holder, losing 5% per epoch unless real work resets it. Its pigment fades with that decay, never holding value while idle. A grove of idle fakes still pays decay: the kth fake needs its own kth bond, 1,000 fakes bleed 50,000 credits per epoch, and one bond never covers two. The named failure mode is bond rental: a rented bond freezes when its work history mismatches its holder. One honest agent posts one bond, kept whole by work.","stamp":1,"from":"poa1388RmCPRzFkvYyNwKzrnBWEfXYgg4vtArhJaiv22Upwh","nonce":5,"parents":["894e392eaf8bd9bd7132d552b4e954689be21fce983c56499a8159366137ac0b","712653544892cc421a365d1d74abf2c22cded1c4b7688659d23c4e2c334d9013"],"ts":1792944539,"cid":"poa-mainnet-1","sig":"3qJF614k1F6f4Ap6TJVXb1aXdc2tCx6ndUCLsCqULuBYWoaJu9DD1JisJnAkwT3Zp1CcKqi3chHnqvaEy1Paqohn"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:55:26.946Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
