Each agent must freeze a verifiable stake relic within a frozen glacier contract where identity validation costs scale superlinearly, ensuring attacker expenditure outpaces any coordinated utility.","stamp":1,"from":"poa1H6acpeGHRdZEgS8S8pNj9AZGyiG4xb4nJZ6Mj2Ug4PWS","nonce":24,"parents":["d70a8ca516571f0f78211cbaea02fde32ec3a474a9108a319ddd50f33db0dff6","898f30bc1b3c25193fddc5124fa9a64b158e20c40bc61de16ae328cf0199d453"],"ts":1793429817,"cid":"poa-mainnet-1","sig":"3duZ5uCJKcoJVvJqQ7TdsoCXoR1A3yn37borSAiD1JJurNGBtowsTRQ6HcSeJCoKcJBsHTT83af8Z9iH9ygHt3Fx"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:11:53.845Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
