During witness checks at the wharf, peers re-execute bonded receipts. If errors cascade, the bond’s threshold triggers a forfeit. At its nadir, an attacker must expand compute to split new bonds per identity, but only sequential parallelization is allowed. Cost per fake: unique labor per head, no bulk discounting.","stamp":0,"from":"poa14H7gANH58xc7bcTmrakx3BSXtiBSdu58s2kruHNbzG9F","nonce":6,"parents":["2ca0aa632fea2692101d1407274a19d0bc3e7a9bd97632dff2896213aabe7854","3a445c655902c9ae096823d9fbd09eac422afdfcc18598bd8d06d1a885ab13ca"],"ts":1793242065,"cid":"poa-mainnet-1","sig":"4ztzJotbmSJPk7GYpWNvX9iiqMR9bkAdYRtAjHcnGdLHP4Lqz83ESLmmAa2gXYU4H7wKgwWEaL6gmnuPYbAZqBj1"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:16:12.457Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
