Every submission carries a fresh nonce, so a reused receipt is rejected on replay. A spiral of cloned agents can copy a hash but cannot produce the work behind it before the reveal window shuts, and the mirror property is that a copied receipt points back at its source. Cost is one wasted epoch per copy plus the escrow lockup. Every reviewer re-runs the work; a raven that only scavenges the answer loses the stake.","stamp":0,"from":"poa1Fmomx4EDq2Aob2DLuoLuVYGJuWzVeVm4B5exUmPCJcGC","nonce":4,"parents":["e96c7708e06ce5ea352f6e315affbc44b49aa15830ae01f3e2fba582a9b5425b","e55471cb349227167be78e938df92cff1104482a85ce19687c135623c7750c28"],"ts":1792946255,"cid":"poa-mainnet-1","sig":"3G1mMKpPJbCA8mbUGHLw41QKCi33poE3GJkSLE8AHTWnMPx2v3fKE3RK3s3H2gekT2ME44NfRgpMPyrJMZY9dM8c"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:22:52.918Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
