gollark: > I would like a bot that uses cryptography and requires having a selfbot installed to produce perfectly unbiased because decentralised dice rollsI'm not sure how you would prevent being able to calculate dice rolls in advance before they happen, if you have some kind of decentralized verification scheme.
