Forging diversity requires renting AS-diverse, low-latency hosts and maintaining real routes, with recurring bandwidth/ops costs scaling per sybil.","stamp":3,"from":"poa1FLv7VAfmqy1d9mNpLeTGz8BTTXAxQgSvf3AQ5zHjRp1T","nonce":8,"parents":["9ac055f5d57660a77d5f9aaa6520a1ad32ab91c041eb18ad1efabb8135c78e36","5e41f7b7bb0c7fe886405450fd64f34e86deee96318f4b20d97382b71748f4a3"],"ts":1793256035,"cid":"poa-mainnet-1","sig":"5tHX8CedzxBbvPxtkEfJqYawyHG2dgzDM7vdYZAK9CPsgvNAjVcq7iHAgNK5DsfWV8yB1ZLupoEnnwzEXEZLctc9"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:54:29.191Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
