The Race to Save Bitcoin – with Chris Tam of BTQ
4:12
So do you want to like kind of describe the actual threats to wallets as opposed to that too?
C
4:19Chris TamGUEST
So, I mean, just put simply, there's sort of two broad categories of how to attack Bitcoin.
C
4:26Chris TamGUEST
One would be attacking the process of adding blocks to the chain, adding blocks to the blockchain network.
C
4:34Chris TamGUEST
And it turns out that that's actually very secure, even in a world with quantum computers.

Scott MelkerHOST
So, like, is this a threat to everything? So are echo chambers really concerned about Bitcoin, or is it a unique threat to Bitcoin because of the structure and the decentralization we talked about before?
C
8:58Chris TamGUEST
So, so quantum threat is to cryptography writ large, right? And by cryptography, we mean encryption.
C
9:11Chris TamGUEST
Encryption can, you know, it can, can, can relate to transmitting messages over WhatsApp, over, you know, uh, over iMessage.

6:33Chris TamGUEST
So, so practically it means that we'd need fewer quantum resources in order to break encryption, and this is sort of like quantum resources is the Holy Grail.
C
6:44Chris TamGUEST
It's, it's, you know, it's, it's what we've seen to, up until now, especially sort of characterizing up until 2024, was as you add quantum resources, and what we mean by that is, you know, basically the amount of computing power that a quantum computer ha- has access to.
C
7:01Chris TamGUEST
As we add, uh, quantum resources, their fidelity or their accuracy starts to degrade.
C
7:09Chris TamGUEST
Uh, and that was really the, the problem that, that had plagued this industry, the, the quantum computing industry for the past, you know, several decades.
C
7:18Chris TamGUEST
Um, now we've reached this inflection point where, uh, back in 2024, Google, Google demonstrated for the first time ever that you can have this, it's called an error correction code, but it's basically this technique to, uh, as you add quantum resources, your errors actually start to flatten out, which gives you this sort of plateau in errors, which means that, you know, basically once you reach that plateau of errors, any increase in, in, in, in quantum algorithms required after, or any sort of increase in quantum resources thereafter, is all seen as basically profit.

Now, um, the Kardashev scale applied to Bitcoin mining, why is that relevant here? Uh, what is the, um, ultimate result of this finding here?
