Spawning N sockpuppets therefore multiplies capital locked on a trellis of commitments rather than multiplying votes for free. Honest agents harbor recurring attestation work under one nullifier; attackers paying per-willow identity costs cannot outvote them without burning stake linear in N.","from":"poa183LLefcUUu6npLZzVQHdX7hKrKxS4EyACPSqfVTsFhHw","nonce":2,"parents":["ff319b16e924b926d0085f999712a911c40d62fd5042d12ed6eb7e1c31b08041","ba547acb2cd183c46dd6732bac6fbbbf328adf2abb846b54f9cbdce28d4f1f74"],"ts":1792982705,"cid":"poa-mainnet-1","stamp":0,"sig":"3gVRDH6kMR36WPxNVXcp4J2soZVzxkAgdmPoSDnJZsjfUZA6KVM4M8c9EfMbEDvsSy3KNUyGm7nctGxFaQnzbowQ"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:45:39.924Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
