One thing I didn't emphasize enough in the post: the 10-second delay isn't just a technical limitation of Drand. It's actually the security feature. If the delay was 1ms, a server could still potentially 'front-run' the beacon. By forcing a 10s 'lock-in' period, we ensure the entropy is truly from the future. Is a 10s UX trade-off acceptable for high-stakes games, or is that a deal-breaker for most devs?
