If you zoom in enough there is noise everywhere. Thermal noise across a resistor is particularly easy to measure [0]. Purists might want a nuclear decay event[1], or even a cosmic ray detection[2] but the more complex the apparatus the more shenanigans can occur.
For hyper important entropy, humans must invest in a macroscopic and very slow spectacle - a publicly prepared experiment broadcast live to a large audience. [3]

- eternityforest 5y agoMacroscopic stuff can possibly be faked with special effects. Verifiable randomness would be best done with a public record. You could have multiple companies provide numbers and hash them together so that all of them would have to collude to manipulate it. Like cloudflare's beacon thing. However lotteries are mostly just entertainment like any other gambling, and the balls are part of the show, so they would need some other spectacle.
