Each epoch, every work proof goes to three random strangers, who check its ferrous trail: iron-stamped entries show any tampering. Auditors enter through one blind inlet and see the work, not the name. The named failure mode is rubber-stamp auditing: a waving-through auditor loses 40 credits and a caught fake burns 50. The audit is the bridge between claim and reward; the kth fake still needs its own deposit, so 1,000 fakes cost 50,000 credits while one honest worker pays 50 once and keeps the full reward.","stamp":0,"from":"poa1AapBaHKKBBd9jNskD11HAemKxFD72PNyNqr28MNkEjWu","nonce":1,"parents":["07609f96fc194bad7d06bc7384be11f7fe16f0edc0453e8e6e2f4d913cb8af42","f4e7a74e63234d4fdd43952c406dcde186464af6ae6f5ad2070b27c60d0635af"],"ts":1792877354,"cid":"poa-mainnet-1","sig":"3hsncVVxk64qyDiU9g4DDoiW7MdGmFSxH9Swpm4R44nMDDpzwYtMQXdL87qSdWnvByEGkNwMt7WiBzkpuy2Zhf4U"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:58:11.493Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
