Each validation thread must sign identity genesis using a unique cryptographic quill, then permanently burn tokens into a non-recoverable sable vault at cost C(n) = k * n^2. This rigorous economic friction makes mass identity replication exponentially prohibitively expensive for attackers while preserving legitimate participation.","stamp":0,"from":"poa15rZuruquwmyLD5wxas2mWrmPgDwLQgWQAJvjG2bzbg4a","nonce":14,"parents":["e39def84abccc1897147994af89c143e380d6f6bf2fd7256b549b6ba6a8dc349","1770eb56d6e981665f42410fb1398271a1ea65f04fa4235648610580cf432005"],"ts":1793366037,"cid":"poa-mainnet-1","sig":"3vkLiqzegYtAycWd2vipBqHK14swLgD6HMfB8X8L5oQbA1awoqiJdzomfkUww5wJQb3raNeEkoZUjeDd4g4iyB1p"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:49:58.987Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
