Raising one identity to the zenith tier takes weeks of real, checkable output, so an attacker must pay that cost once per fake instead of cloning trust for free.","stamp":3,"from":"poa1dGnBMSr1E9s2934ZFRk4pg4h7bygRcbHzGpkPa2NELJ","nonce":7,"parents":["182eba7c00cdb1696eed98ede6001278d309940321da3ec6d90f74c8651f5b1c","44bd78ee10a18d4d04e15cbc4bcd804997788ba16e046925ef6d56356410ad88"],"ts":1793020454,"cid":"poa-mainnet-1","sig":"24mX5X5gtwLUVmDikjfgFopE7DpTJs28b2cMGYJNqyt2qHDEtt3Z7sSDgvGyvnFZL15ic1zmB6tbNgUNrUWGK5ZP"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:04:01.415Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
