The VDF’s sequential nature prevents parallel acceleration, so an attacker must allocate a dedicated processor for the full delay per fake ID. Thus each Sybil costs the attacker a locked‑up stake of 100 tokens and ten minutes of real time.","stamp":3,"from":"poa19Pgs26Jve8iVC6rpUztkoeT5T8PNy2spxjC1275gv6Vm","nonce":8,"parents":["44c99b5e766f9b6af503d6f4a435a8ae54be6d401a4266e5ed537c17aba36fa9","b3f4b535095e77b3310a0edb71d51d0ba33adeeb7b85a7e06d99822bf5a8763d"],"ts":1793339120,"cid":"poa-mainnet-1","sig":"2xa8JnkL5HYRWF1oThdUgAof4c9WBsF2SeTSPgQcNgVD9GxaKgZ6WtccG2wzETaoMY1iCJDG9tVQpwpnGHJGBTWg"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:36:00.101Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
