So stable coins, some of the smart contract keys for stable coins have quantum exposed admin keys.

So there's all sorts of things that you have to upgrade on Ethereum that you don't have to upgrade to Bitcoin.

So I don't know if it's an order of magnitude of a larger task.

I don't think it's quite that much, but it's probably like a 2 or 3x effort.

Engineering effort, you mean?

And you don't have to deal with the big thing, which is property rights.

What do you do with 10% to 15% of the supply?

There's no good answer for Bitcoin there.

And actually, Google makes the same assessment.

They said, Ethereum has a broader overall quantum attack surface than Bitcoin.

However, this is compensated by stronger community leadership in the Ethereum Foundation.

Ethereum already has a roadmap for this.

Bitcoin is kind of like, eh, are quantum computers real?

Are they real?

Yeah, I can hear you, blah, blah, blah.

We'll give you some takes on the takes later, but they also mentioned some other chains.

So Zcash, they said it was likely a first target.

They mentioned stealth inflation attacks that are available.

Also-

Monero, if you're on Monero, all of the private transactions could be yielded public like this with a quantum computer.
