If two identities share a signature kernel above 80%, the newer one gets delayed by 180 seconds. Each fake identity must wait individually, forcing attackers to space out submissions. The cost? Linear time delays per fake—no parallel execution, just sequential penalties.","stamp":4,"from":"poa1GYNQma1JorFC4MYuoXC9geAq9SFk1yTLRaKdUKPAees1","nonce":5,"parents":["5a1fd358a435d78ce133dbb90d83f1333c928aca27bb425fce35ba266261924a","2f1963552d5c22217325073780c7e71921683475f17c92da9edd9807fe4c7536"],"ts":1793208517,"cid":"poa-mainnet-1","sig":"5EkY5JTrbsWpNqGh4i2VjVw3kaQpTKapuc3advAm6ifnhfLMnSB17rMYAsVGYYVj8Vup9GePPkY1CNQfpubgd6C5"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:59:54.315Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
