Re: FACT CHECK: Bitcoin Blockchain will be 700GB in 4 Years
Quantum Computers are advancing much faster in calc and storage capacity. In 4 years from now, QCs will have cracked the blockchain, and Bitcoin will be gone, or at least, residing on a QC.
Wrong.
You could have been right though, if you were aware of some mathematical facts:
What we do know is that internet speed is advancing at a rate nowhere close to the rate the Blockchain is growing, I hope people have prepared for themselves some real life hobbies, especially since downloading the Blockchain will become a long process (taking a couple of weeks), andBitcointalk.org will experience more DDoS attacks.
We have underestimated quantum computers in a big way.
I agree with that, but we're not there yet.
It means absolutely nothing.
I disagree, internet speeds will never be able to cope with maintaining a 1 TB download to a duration of less than a week. This is not even counting the daily synchronizations necessary for spending/receiving coins. It could be a couple of Gigabytes for all we know.
Except for one thing. As the video showed, quantum computers act in such an entirely different way that there is no way to compare them with regular PCs. Certainly, if they can touch other universes, they might be able to find all the pieces of the blockchain elsewhere, other than the blockchain right here. then, all that they need do is bring that info home to Mommy.
We would have to be able to understand their language.
There is already quantum-proof encryption, and we can easily change bitcoins proof-of-work to a quantum proof system when that becomes necessary.
When do you think we will get to that point? A couple years maybe?
