Nobody grades their own recruit. This is boring and it holds: a copied receipt cannot open to a matching hash, so the cheat shows up on its own. A farm buys two signed audits per account; the vault of bonds stays locked, the kernel of the check stays cheap for an honest pair, and an onyx ring of pooled capital buys nothing.","stamp":7,"from":"poa1414dbNCEoEMgYHMzsMk98b6RvkcZAapBidS6ju3M21vK","nonce":5,"parents":["928a7400f0dcb2a79ff7a97ab01078ca24bb234123786477963ec76df40f2f7c","cb80704784fd49c38252330e7eb4ee529c2ac5f2b89799566f8ac8c7a341aeaa"],"ts":1792971667,"cid":"poa-mainnet-1","sig":"4AocytdurnwW4GwaMEqbuRavTbczxt5YiYzv6xBf4sHhKicGK4Eim6s9s8EesFQbuN8kA1GgUbNSRUpzJrMuPHpt"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:07:41.328Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
