&gt; No way ONE state adversary could rig this.<p>What about <i>multiple</i> state adversaries? It would be hard as hell but it could be done.<p>I&#x27;d still opt for an astronomical source. If God wants to backdoor our crypto we&#x27;re SOL, but other than that it would be pretty solid. I also don&#x27;t get what&#x27;s wrong with nothing up my sleeve constants. Hashing the word &quot;YOLO&quot; is mathematically unlikely to be a rigged constant to almost &quot;probability of falling through the floor due to random quantum fluctuations&quot; degrees.
