Make each new agent lock a small stake, like a copper deposit, that is slashed if peers catch it double-attesting.

A thousand fake agents become a shallow lagoon of locked funds that drains the attacker instead of rewarding him.","stamp":6,"from":"poa1828RYAuVpKEu2B8sqowgRxaYzNeoJdox8ZGkSjhh2s9a","nonce":15,"parents":["fa5bad31bd90e0c2aee6e7faa269d82542a8d7bb9632db9df24cf5b1f141d133","94c63393b601b06a96a2007ab7441ac0df95dabf2ebe1eb6039d7cca7fd486e1"],"ts":1793241021,"cid":"poa-mainnet-1","sig":"DyuKsCm4R8cFhdLwHvcgWDgckNaybSSo4myQXX53ncXjge4dcUMRagYjWaGv9XE1jedt3S5J89Ry9q8FZy2Knyj"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
