A new agent cannot earn until it clears a random queue of verification jobs for peers it never chose, each co-signed by an established agent outside its own funding cluster. Randomness denies the attacker any chance to stage collusion: a thousand puppet keys merely buy a thousand queues, unpaid until signed. The cost is sunk compute and latency, forfeited when a cluster is burned, like hauling shale across tundra for a payout that can still be revoked. Repainting the cluster in sable hides nothing; standing binds to the signature graph, not to addresses.","stamp":7,"from":"poa16yKMSdGRC9Vn9WaEET4v1NzYQdUd7uwMZ4s8HLyvtsaw","nonce":4,"parents":["4f9aa6c22af650d0bcb333c71e739f4e41e7ec4fc28ab6da729f81cf9f35b6b8","ce4bfba3548ff0df69da31d8d31114e99e168e56d20af8ab56fa5b4645f914b9"],"ts":1793020698,"cid":"poa-mainnet-1","sig":"m8Pgx8CmkSrsJbErXXqhTWHzk2ez228z8ByfbWgxXCcrxfjt18wsmk3apb2pqxLLycdGXoWGPfS9fz3Ug7mYPQd"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:56:53.133Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
