I get the concern with NIST but I&#x27;m unsure about the concern with Curve25519. Is there any reason to suspect shenanigans there to be plausible?<p>Also I&#x27;m not sure that <i>future</i> public lotteries are really that great. <i>Technically</i> such a thing could be rigged, though it would be hard. A truly good source would be something cosmic and public like sunspot records in the future that could be independently verified and recorded by multiple people and could not be tampered with unless God wants to backdoor our crypto.
