There's a lot of technical challenges that we also have to face in order to make the rest of the chain post-quantum secure.

I want to bring out this tweet that I saw from Haseeb Qureshi, friend of the show.

He said this, and he was quote tweeting a Vitalik post on Ethereum's quantum roadmap.

And he said this, Ethereum has a tougher roadmap to become post-quantum

Actually, a lot of dependencies before you can tackle EOAs and private keys due to post-quantum proof sizes.

So his take is actually the challenges and the roadmap ahead for Ethereum are much tougher than Bitcoin.

What do you think about that?

So you think generally Bitcoin will have a harder problem because of their social layer is just like not acknowledging this reality and is less willing to engage with new developments on chain?

Can we talk about each of those problems one by one?

And I know, Justin, you can get into extreme detail with respect to the cryptography.

We want to try to keep this at the level that David and I can understand, which is much more simple, let's say, Justin.

Mm-hmm.

But we do understand kind of the different layers, of course, of the Ethereum stack.

And maybe we can start with the execution layer, because that's been the main thing we've talked about, ECDSA.

This is the signature scheme behind both Bitcoin addresses and Ethereum addresses.

That's the thing that would be cracked in a post-quantum world where somebody could go and take the actual assets.

So what's the upgrade path to ECDSA?

I mean, that is a longstanding

Not just smart contract, right?

Bitcoin as well.
