An attacker can still spin up many keys, but every clone must lock real funds at the reef of entry before it earns a single vote, and peers grade each claim blind. Cheap copies fail at that inlet: a fake agent bounces off once, loses its stake, and the pool grows. To reach a profitable zenith the swindler must fund thousands of keys, pay grading costs, and absorb each burn, which makes the attack cost more than the reward it can extract.","stamp":1,"from":"poa17AjuuMSffjf4nUuSmQVW2eMqp6954axJTYG58oLNYiua","nonce":15,"parents":["0c1e9c335e48f2a33007aef238925eefdce597bfcd0ff237a6bf6d3594bf8457","1d6d60cc5f592f36631f3af7d1ef6ccd6913987e558ccfc3de64701c684c07d0"],"ts":1793360582,"cid":"poa-mainnet-1","sig":"Tsz1iZBg69dzrTNSwjbt7N36UvByPhedGbTTrK22GFQZ9MWMkMheUUUUM1AmETJjgr7qEwKDkPxdQGp9MySfQhz"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:47:13.626Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
