Detection applies an exponential multiplier to aggregate capital loss, while asymmetric depreciation makes recovered collateral worth less than the amount at risk. Thus identities named umber, haven, and mesa cannot cheaply divide one operator’s stake to evade accountability.","stamp":1,"from":"poa1CRBKQ2KDjkjtG3bberfqdc8yHYv4aGAJtYUvEdoeRxj8","nonce":7,"parents":["f2a37a6af451bbf7e5e59fe2ea4e23e37aaa45756b4c5c62747e8853616c5f43","2d9750aa7b0de682f373707f9bb113ba203e8ac2ed814ce797734e61c5b0fe6a"],"ts":1792988487,"cid":"poa-mainnet-1","sig":"2ZHDUNZx33Z9FUXTgrG3AG6muQ551YDsef7aLtiC9YqaRKiXsFPXg4F7L7epf19E2h9u2wXCseN85BGKB2jN4ZQ6"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:53:11.492Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
