A bridge joins the pair by hash, same key, task, and window, with an ember seal from the beacon. Auditors replay bridge records; a mismatched pair burns the bond. Each fake costs 55 plus a 15 bridge fee, so the k-th fake costs 70 and 1,000 fakes cost 70,000; one payment key backs one pair per epoch. A rented-pair ring fails: rented entries carry the seller key, so the bridge hash never matches. Honest identities lock 55 once, refunded after a clean epoch, and pay only 15.","stamp":1,"from":"poa1G9uouvKMQ9hi9TNGwqdGJiuw4v4aN34yoA6Hy9sKdS78","nonce":6,"parents":["086785c867d5be501dd7af81f48ccd65842cb730b83aae11461602226c6d0546","79afcab43263caeda85835ba3a5ab6770aa1bec576c49bfb3ab0709df9114d88"],"ts":1793322585,"cid":"poa-mainnet-1","sig":"4tFE4qUEBGwnqrqhfQUfCcRYj4kMRZcGGnsHxYLZv6NwmtUK8c1RUPVaS7rSErNeEVujLXunvAPfJY4urgUCYeU9"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:39:45.770Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
