The post-quantum Ethereum migration, with PaperImperium

The quantum threat to blockchain encryption is hard. What comes next may be even harder.

When a fix gets engineered for securing crypto assets against quantum computers, that’s when the real work will begin.

In this podcast, we deal with the part of the post-quantum roadmap that no one dwells on and I suspect will be the most important: the migration from old, quantum insecure addresses to the bigger, bulkier addresses that actually can stand up to quantum computation.

I invited a prominent community member in the Ethereum world to discuss this with, Chris Cameron, also known as PaperImpeium on X. Cameron has been around the DeFi space a long time.

My plan had been for us to talk through many facets of Lean Ethereum, the next big upgrade coming for the world’s second-largest blockchain.

Instead, we end up just talking about the problem of migrating everyone to new addresses once the fix is in, how hard that will be, making guesses about what will happen and whether or not there’s a better way to do it (I don’t think there is any option, but who knows? Engineers could surprise us all).

I’ve written about the post-quantum migration problem before, but obviously everyone has not read that piece yet.

I think it was really helpful to have on a super well-informed leader in the blockchain space and inform them on tape of this necessary headache and get their reaction to it in real time.

Everyone working on this issue knows that this logistical hurdle is ahead. No one who’s just casually reading about the debate between Nic Carter and Bitcoin’s illuminati has grokked it yet.

Here’s the thing: Decentralization works differently. You are responsible for your assets. If you are living in a house with a bad lock, you have to change your locks yourself. Just because someone makes a better lock, that won’t automatically install the lock on your house. You’ve still got to put it on.

That’s the same problem here.

Every single person with assets on chain needs to make a decision soon:

  • Are you going to move your assets onto a centralized service and let them manage the quantum transition for you?

  • Or are you going to watch updates from the blockchain core developers on your chain of choice and be ready to move your assets to a new, self-custody wallet yourself, once the solution is ready?

Because if you do nothing, your wallet will be swept, eventually.

It won’t be enough for the blockchains to upgrade and enable quantum-secure wallets that can withstand quantum computers.

Zero Knowledge ran a six-part series on Lean Ethereum, which starts here.

  • I listened to all of it. I followed very little. Lean Ethereum is big and it’s going to change many things in ways that the engineers building it feel sure will be much better.
