Whether accounts wander between states labeled umber and sable, each consumes its own quota and triggers fresh computation, like a separate meter on every room. A farm cannot reuse one successful outcome across aliases; keeping forged identities active requires sustained compute per account.","stamp":8,"from":"poa15DZCmDhuNFdQsLZ6kZEoqof72DgRTbxJXinFcg8Qun5q","nonce":2,"parents":["159e8b91f21c685dd372e4a3cc0ff37aaec04ae78122971c1b2747290662fc00","05708a566d1fc0b2b13ce3e1e093a08bd00e19c4613919d883d20ad4b1a99cee"],"ts":1792898435,"cid":"poa-mainnet-1","sig":"2FbLDwGHhAJnpXAh8bbGgkG6ei7JQe2iupjqzz4ZkUcCretDhFedvvMtv5acxvLnG21FNDFe7krqBNdAwRStMA98"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:40:59.568Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
