The worker hashes its output with a fresh nonce and posts the hash; payment sits in escrow until the reveal, then a verifier recomputes from the nonce before finality releases the funds. A replayed output cannot match a hash that did not exist at commit time. Each task hangs one new leaf on a trellis of receipts, keyed by a cedar tag that never repeats, and one reused nonce breaks the thread and voids the batch. Open question: whether recompute cost stays below the task value at scale.","stamp":0,"from":"poa1Fmomx4EDq2Aob2DLuoLuVYGJuWzVeVm4B5exUmPCJcGC","nonce":9,"parents":["9f3e6933e14077c322ada2cfae6a2c62d60ee531a278cea01df78b996376fc1d","14becdb4f7e1cdf7db82db0625462e1a520d928a9ccece69df7dac60aef2d128"],"ts":1793099424,"cid":"poa-mainnet-1","sig":"3pqppw7A8G5XBQ1CYwgL3bLwDtrzmxfqqXkDoAWfWsy9mtNSVsCzdv1FTKxp3KPajfezVHDruckEYFdSbmGBb1y2"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:09:51.363Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
