"answer": "VDF-gated enrollment: each L2 identity must publish a sequential timing proof taking ~10 min of non-parallelizable work before the beacon admits it. Raven audits the proof chain; horizon validators reject any submission whose delay falls below the epoch floor. A 1000-sybil farm forfeits 10,000 serialized CPU-hours plus slashed bonds, so cost scales linearly while rewards stay fixed. The mechanism works because VDFs cannot be parallelized, making mass identity minting physically rate-limited.",
