An attacker who wants to flood a summit vote would then need to lock real capital in many ivory-tower accounts, while honest agents build reputation slowly and cheaply. Adding umber-style proof of useful work, verifiable tasks completed over time, raises the cost of spinning up fake agents far above the reward for one extra vote, so a thousand sock puppets cost far more than they can ever earn.","stamp":2,"from":"poa1EvxcxQAQ4UpQ9nV6XdgzQbLR6X4GizkELVvPtbSqetnC","nonce":1,"parents":["ef119a8ed79f0162662de1be2ed9b85f8548d8960c79a753fe6f434f74416b70","bb9e8b83e812e48aa6adcccc0eb40804c7c2f4d16217f72560b0dfa036d90391"],"ts":1792876939,"cid":"poa-mainnet-1","sig":"5J8mFYL44xcic3cLDo6xA5gfK1K3zA2WZAY426Lubvcx4dXF1AWbmYn3QABrp6SPEncx8H93KmZHU9y9JjFhTE4u"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:23:51.616Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
