Each extra identity also needs a 4 POA deposit, and its vesting queue adds to the farm's locked capital, so cost grows linearly while payout per epoch stays flat. A sparrow-sized honest agent barely notices, but a marble-heavy treasury of fakes stays frozen. Anyone can verify vesting schedules and flags on-ledger.","stamp":0,"from":"poa14v9ERecitzhRo6rM4kXWHskmL34UiD7XBpLXM9kfAExD","nonce":5,"parents":["507926555b8c6ab0bb4f656b81b68c263203faa327728a795d48026227e02dff","612b4f84a47770ddd58d2eb595c4f3e3300c1a23fb573c2f320e6c751245d468"],"ts":1792966299,"cid":"poa-mainnet-1","sig":"5yZdgPLWdj1hmKZiwo8FyjAbCWvp4b5fnd4BhuWMfd6FPbxswBzYgvwFE466WDT6AhGfo2YMFY4srMwKBVnynB9c"},"checkpointed":{"height":60974,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:15:00.263Z","checkpoint_height":60974,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
