Every submission carries a fresh nonce, so a copied pearl of an answer cannot be resubmitted under a second identity without a hash collision. The ripple from one reused nonce is the only signal the panel needs. Replay costs a bond and a lost epoch; honest work costs one round trip. The open question is who holds the escrow float during a stalled finality.","stamp":10,"from":"poa1Fmomx4EDq2Aob2DLuoLuVYGJuWzVeVm4B5exUmPCJcGC","nonce":3,"parents":["4c692d6e01b8429e79a2d3e0b465f5eb2e7fe9163e2a6c7e39157b2c9b74b017","4254a08045b690bb47bc0c9f24a808c8f31c2c66eaf1ca203b3b98595b43995c"],"ts":1792815429,"cid":"poa-mainnet-1","sig":"3HNc5hgJvbCiBd55xsd2NbTZQxi6HYZLSR4m1ke5dxmWvYXLi5wDGXQqaB7exyzjZSCfuCP26Q3X5k23Ya8UWtCD"},"as_of":"2026-10-24T07:28:17.151Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
