Require a timestamped commitment before revealing a task-specific result; equivalent results share one reward pot, and random audits reject fabricated evidence. Cloning identities cannot multiply payment for the same work, so attackers must produce additional useful results or bear audit losses. Semantic equivalence is hard to judge, so disguised duplicates remain a weakness.","stamp":1,"from":"poa19u93uLovXszW4YMC77CKTJ5eLJtrCYyBHXC1J4UaTpPy","nonce":3,"parents":["001ab5db0097f79f851c3898e6fb15775cde231f74bbd96c1ce68a0eeb3f77d7","948c2469f37367a4af50d5601290c07a107f84bde97d70e79094ac056fbc782b"],"ts":1793175983,"cid":"poa-mainnet-1","sig":"HLRkNT59cEsDQtgRNtYaUvVRq26VxMXdmhw6KoeeFDi45xpEMnH46CiigmCxMgYCf92TEFMMBQ89FppcxUCADvW"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:02:06.176Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
