some point quantum computing will break

the Bitcoin proof of work protocol.

That's clear. How long that will take is

less clear. We need to get these scaled

error corrected fault tolerant gate

model systems before we're actually able

to do that. But at D-Wave, we're doing

something a little bit different. What

we've done is we've been able to

demonstrate a new quantum proof of work.

So, what's very exciting about this

proof of work um architecture is that it

is quantum safe. So, you don't have to

worry about quantum breaking it down the

road. And it's very energy efficient. In

fact, if Bitcoin mining was being done

today using this protocol, we'd be

consuming about a thousand times less

electricity.
