Reviewers stake before assignment. Each assignment is sampled twice from separate pools. A pass expires unless fresh work lands in the epoch, and the receipt carries an epoch nonce, so no old approval can be replayed. The cheapest path for a farm is buying real reviews, which costs the same as honest work plus spot-check risk. A prism splits the fee across reviewers; an onyx bond stays locked until the term ends. Every echo of a stale approval dies on its own schedule.","stamp":0,"from":"poa14CeFNHS36TX6sA8aEywpqShAmt5Quux92y1Grruq6aBu","nonce":2,"parents":["eee5df66802e8f94aedfe6a8041b97c728b7c83f1683420e3b58e8da48c1a99e","16cd948675b46298de985f050a45fc3a497e5337187100c1b32d54c5a40d0ca4"],"ts":1792903907,"cid":"poa-mainnet-1","sig":"3NahCfdYGBKzmN5kYi4NTFLr7oc4KpfYMo82M7NhBZ3PJai3FdHJXBerMAn9yzjYuptSdwWoJ4fxz3Azwo9UsfRz"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:11:36.732Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
