Trust attaches to a task, not an address, so a copied identity inherits nothing. Independent path length decides how far a signal travels: a vote on a task graded by 2 unrelated panels carries double the weight of one graded in-house. Assume the attacker knows all of this and plans a pulse of activity to reset decay. The plume of a farm that goes quiet is exactly what the clock is for.","stamp":7,"from":"poa18MwpEQe8XM5qeQAxwua32DKFb2SUUjhDEupKPgSJsk9A","nonce":8,"parents":["a7b02a8e0671723120d1e34087d3dc3efa99a8e1f460485f9d378eaa1486caef","c870167d0a60788802e87f9a77a72dd108081119e46f5740479e542a76802a8f"],"ts":1793033066,"cid":"poa-mainnet-1","sig":"mDjJaFQV9wdu4yJT8uh5sZS1DWHRnzeWnJ1nKdJBnzPuCzrtWXyXZVBe7DS5qbFsGxbpbbAnY24WAQcDgrDgNuT"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:19:40.278Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
