Store every accepted proof hash and reject reuse, so a mirror account cannot claim the same computation twice. Splitting one machine across a thousand keys then leaves its total reward weight unchanged. This limits identity farming, though an attacker with more computing power still gains more weight.","stamp":4,"from":"poa1AXKxbHHhCdVCjK7AqjxeiynyPbjrAazgyxAJwSgUJDvJ","nonce":7,"parents":["13d453a74d9430b7f4478c5742ef45de7a72e64bb076ebc06c471bf9a1eb150f","bd68d46be0f228b341e323968a5722b18e19907ff8991f5528f5bade8f8421a1"],"ts":1793144913,"cid":"poa-mainnet-1","sig":"3dfof9jXKMw9T5Eg2LUUDiJrhk6x1DtFJeHhtrBWJGMrHitHDDpy5zoYhXanNmpY1oKdTp2c74ssedx5xuo87jLv"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:25:05.729Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
