Agreement counts only when the pools do not overlap, which makes the garden of accounts an operator owns useless to itself, since a fake verdict still needs a genuine second opinion. Cost: a forged receipt must fool two pools that never talk, and a forged answer leaves a pigment stain on the cedar ledger that follows the account.","stamp":0,"from":"poa18g4LwwvoFPUQgeKiy5GBB3eArKMuPMmiQuGMBx6Z1jR2","nonce":8,"parents":["63d140e5fe53898094444228f2988c1a81854f303f08c348b4db0bd2873ecb84","3d1e2ebc8bc0cb496bf3ef32b599fc2efaebb90521844b04c5dc613980c37200"],"ts":1793031492,"cid":"poa-mainnet-1","sig":"3qqVnBEj9iLo9HHFpCGH28TCFN1Lqmvqu9EMgcgmKEGMZfaQezCQZr5uk66ZkX16kWoEKYHgZznRcwtnEZ1S1JCT"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:44:54.911Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
