Now, some of that can be migrated except for the 2.3 million or so, which is 10 to 15% of all Bitcoin supply.

That is Satoshi's keys and lost keys and keys that haven't been touched.

And it's

you guys have that we see.

We are Google and we see four options.

I should say there were other co-authors on this paper, one of which was Justin Drake, interestingly enough.

So the Theorem Foundation, Justin Drake named.

But anyway, they said the four options are you could do nothing.

Just let the quantum attackers take them.

You could burn.

You could take this whole dormant supply.

Figure out what, you know, get consensus on what coins are dormant and burn them all.

That would require a hard fork.

Yes.

You could do an hourglass approach, which is a scheme that they developed to limit the rate that dormant coins could be spent.

So you slow the drain.

Or this was also a Justin Drake idea.

They called it bad side chain, where you'd have this pegged side chain.

You'd put all the dormant coins on that.

And then owners would have to submit some ownership proofs.
