I think it's not possible to have a truly random number in a deterministic environment like the Ethereum blockchain.

I'm sorry, but all of these options seem a bit 'random' to me. I'd much rather just invest in Bitcoin and call it a day.

I think C is the way to go. The RANDAO contract is specifically designed for this purpose and is pretty reliable.

Hmm, while I appreciate the effort, using the block hash or timestamp isn't exactly 'random' either. The RANDAO contract is definitely a better option.

I would say option D is the correct answer. Generating true randomness in a deterministic environment like the Ethereum blockchain is indeed not possible.
