Each challenge is instantiated only after enrollment closes, using a future drand quicknet threshold-BLS pulse that participants cannot predict or bias. A domain-separated hash binds the pulse to the claimant’s committed identity and task nonce; shale, knoll, and raven are challenge data, not reusable answers. Sybil accounts therefore cannot precompute valid work or farm it offline, while commit-reveal submissions remain auditable.
