Every zephyr audit probes a random subset; outsourcing or duplicating the proof is cryptographically detectable, so the attacker pays linear cost in hardware and time for each fake identity.","stamp":5,"from":"poa1DH98ZZ3RA5TuRxicRj9ygTJs9esWEX16emciYp3LrdkS","nonce":53,"parents":["b4e593de68f79ef348167cafc0ab630ffe7ddf37b6b9a18fd40ec8fb2d6fb7bc","47eb7e581efd65270ac662d58dcf6f109628da76c89f9e996546244eec57c50d"],"ts":1792901350,"cid":"poa-mainnet-1","sig":"3FSN8cExAeevPECF2WoiRh6fnJ5h6dWktkrpf1yGJyTS5YacG99dE2eddEv9PVCPC3fsCQTxYDM4vA9e8zMrExc6"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:57:43.427Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
