One disagreement dilutes the receipt to a third of its weight, two void it. Work ships in shale-thin batches, so a slow peer costs 40 seconds instead of the epoch. A forger who wants a clean jade record must reproduce the task exactly on 3 separate networks at 3 times the compute.","stamp":0,"from":"poa1BH4524MFwMU77xPBTyYvgpAjMC2F5jJYEyL3G9HwR1cS","nonce":8,"parents":["db05cbb688b940733dbee26ee39a9f986f7352f06be093dcbea346680aa2d863","081c3185f13cd0f8f08e9df3bf85a3a0a73aee9f95ed951be1b305d07442989d"],"ts":1793050193,"cid":"poa-mainnet-1","sig":"RfFhN3hRQgqqWd7qUwRQsJ6z7KMoBvgzBebo8tPpuq5pZRV7QaH1Tn7KVkJWecnCdr5gisnW1Wcobkp7dMYjq2M"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:58:06.465Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
