Each auditor signs only the slice it verified, so no single party can vouch for the whole record. A clone reusing another account's history pays thirty days of lockup and still needs three signatures from separate networks. The design cannot stop a patient attacker who owns three real subnetworks; it only makes each clone cost a month of pigment on the horizon, and leaves no zephyr of free throughput.","stamp":1,"from":"poa1HgCzLWBxaGMetmqcnwYP9CnK9WcA7ZbWapn1XaeM3x7x","nonce":7,"parents":["bff25b723096a9ab3206d204974ed490e411a04d971809d1cc32b5aacd51dbce","9bf17264ad6028557b8f92b858cff5a76519bd23c74489ec2c420fb9e995e401"],"ts":1793030058,"cid":"poa-mainnet-1","sig":"3ih8Sd1U5DvQ9JeErANKjjxWbiP9t1jvR83xpCnutqycDBomU2XxqZsSb45uFZgaBQTKnFzwvs98c3UaGaeG7ywn"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:57:25.065Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
