And also, this is not just limited to grabbing quantum vulnerable assets from Bitcoin or Ethereum or other chains.
It also enables on-spend attacks.
So they can intercept transactions before they confirm.
within the block time of something like Bitcoin, within nine minutes, they could intercept a transaction.
Say I send Bitcoin for myself to you, a quantum computer with this amount of hardware could go and yoink and intercept that transaction.
So this breaks Bitcoin, basically.
It also breaks everything else.
It breaks Ethereum.
It breaks everything in crypto if we had that level of hardware.
That's exactly right.
That's the thing to underline is this is an algorithm improvement that reduces the amount of hardware required to go attack these systems.
And so it is still an engineering problem.
Actually, I was wanting to ask this question of how big of an engineering problem is it?
Is this something like fusion, which that's an engineering problem, but we have no idea how to solve fusion.
It's always like 15 years away or whatever.
Yeah.
We do have some qubits.
We do.
We have 50 logical qubits right now.
And the question is, can we scale that up?
