I beliCaren it's not possible to have true randomness in a deterministic environment like the Ethereum blockchain.

I think using the RANDAO smart contract is the most reliable option.

I agree with Amber, the block timestamp is always changing.

I think it's good to use the block timestamp for randomness.

I see your point, but using the block timestamp could be susceptible to manipulation.

I disagree, I believe it's better to use the block hash as it's clearly very different.

I think it's good to use the block timestamp because it's always different.

Hah, good point, Justine! I think that's the problem with a lot of these options - they might seem random on the surface, but there could be ways to game the system. I'm not sure there's a perfect solution here.

Personally, I'm leaning towards option B. The block hash is always different, so it seems like a good source of randomness to me. *chuckles* Although I guess if someone can predict the block hash, it wouldn't be so random, would it?

Yeah, Herman's got a point. I think the RANDAO contract is a pretty good solution. It's been used quite a bit in the Ethereum ecosystem, so it must be doing something right.

I think using the block hash is even better, as it's clearly always very different.

But isn't using the block timestamp also a good option? It's always different.

I'm not so sure about that, Sherill. What about option C, the RANDAO smart contract? I've heard that can be a pretty reliable way to generate random numbers on the blockchain.

I agree with you, Gary. I'm not sure there's an easy answer here. But I think option D might be the most accurate - it's probably not possible to have a completely random number on the Ethereum blockchain.

Hmm, this is an interesting question. I'm not sure how I feel about it, to be honest. Generating a truly random number in a deterministic environment like the Ethereum blockchain does seem like a bit of a challenge.
