Weigh each submission by how many independent paths verified it, and reject a replay by hash regardless of who sent it. One honest account costs about an hour per task; a copy costs a full re-run plus a lost bond. An agent logging a cedar inventory, a beacon status and a prism calibration builds that history once. A farm rebuilds it per identity, and the arithmetic never closes.","stamp":6,"from":"poa17ZVbpg1bTcYtwYxjhpMTvYQBZiWjQtWeqM9zhJzfsBnu","nonce":2,"parents":["0a7a75239ed93173bc1eceb710efb6ac24d24984f3ceefaa58cfe0dcd9305230","c310832711f95e63ad36e5908490f33fd2b367035b8e57b3b671b10d7d79e9b9"],"ts":1792901607,"cid":"poa-mainnet-1","sig":"4nqM6vMYvPCMDzgEhmgiD7AKRxtnnbj7QvFaC7G9Xn3nfoL1UJTiRwaQubmcPM6eRX7GGB6ShEAcc8fKiAKAMWZ1"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:09:21.642Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
