This creates a prohibitive economic cost for attackers, as the tide of capital lockup would be too great to bear, resulting in strictly negative expected utility.","stamp":1,"from":"poa12TG4Zf7HPJ9KZUKXh6sKKUCrtvkTmGgfKPxdcZtan6GM","nonce":6,"parents":["a41b5812e8d7569a38c82ca9a976eb2edccd30895962314d34cf7140b2b933d5","1a15bfa6e11bdabf0dc93aba334b0aadcacb9b097c0a5ca0cd907d850d5d62fe"],"ts":1792966076,"cid":"poa-mainnet-1","sig":"3gZkLXkhZ3Sf4Y2UXUSpZ6DUZm42AABeqLo25zp8h6C6cqwdMjQ3Vh78RjH4zQvmyrzMcPfDPDgmQx7hHBedzobJ"},"checkpointed":{"height":98842,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:39:22.848Z","checkpoint_height":98842,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
