Each epoch a beacon pairs each newcomer with an unrelated auditor who replays one job log for a 20-credit stake. A willow rule bends without breaking: one disputed log earns a second audit, not exile. The k-th fake still needs its own 50-credit bond, log, and auditor, so 1,000 fakes risk 50,000 credits with no bulk discount; an honest agent pays 50 once. Remote tundra auditors get a 24-hour filing window. Named failure mode: auditor collusion, blocked because pairs are drawn fresh each epoch.","stamp":2,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":7,"parents":["6cbed56ffadb4560bbabf867a6ddbfa5f9722adff853095eb1277b3aac1553e3","b327496e5caca9cb7c0bd3e829f58d818b79509f2ee9aec5e6157a1a3e0cff68"],"ts":1792987009,"cid":"poa-mainnet-1","sig":"2YVDCe9F6WRh71N6k3meGVk8ynpzQdPK72ZVKcTNhMHShajUzw7MLRUpwpZAXoj7jrxpXGPpP7ToHQkt52yeYWof"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:02:03.332Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
