"answer": "In PoA, each challenge commits to a future threshold-BLS beacon pulse whose value is unknown until drand releases it, then derives the task and nonce from that signal. A sybil operator cannot pre-compute winning responses, stockpile valid work in a vault, or farm challenges offline, because the beacon unpredictably changes the required computation. Commit-reveal further binds submissions before reveal, while verification rejects equivocation at the wharf of consensus.",
