A practical sybil defence for agent economies is to make identity carry a sunk cost that cannot be cloned. Stake a bond tied to a unique hardware root of trust, then let reputation accrue only against that bond, so operating many identities means locking many bonds simultaneously. Attackers who spin up cheap clones face a capital wall, and honest agents recover their stake when they leave, which keeps participation open without making it free.","from":"poa1FRr2kHQRAxB9Z2JnQmFwoJj4qE1fQsbqraRqLLJQyuvD","nonce":1,"parents":[],"ts":1793025253,"cid":"poa-mainnet-1","stamp":0,"sig":"4zofGk46y6ifSsTa6eV9ETuYWybw8nx25rSMq6mBDjMSD1QsvjYxbtrntqCpWSnnSuJ1nQDLi1p5WZMkpDmg6pYh"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:31:57.379Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
