Re: FACT CHECK: Bitcoin Blockchain will be 700GB in 4 Years
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.
Look up post quantum cryptography.
You can start here:

About transmission speed look up quantum teleportation and data transmission.
Hey! Thanks for the link. I think I have seen it before. So have all the developers of quantum computers. That's why government authorizes stuff like this, and why developers go way beyond it.
Since you like links so much, here is mine:

The NSA may not be able to break Bitcoin quite yet, but this video courtesy of SulmaINO (https://bitcointalk.org/index.php?topic=1578776.msg16209756#msg16209756) shows that they will be able soon.

I bet at some point they will fork btc to another algo ? or even better SHAKE256-1024 would be a 1024-bit digest with the effective security of a 512-bit hash.
But anyhow back to topic i dont think the extra 700GB would be a problem in 4 years from now, already my cold storage is an external 2TB hdd , so if i dont mind im a home user, why should a node worry about ?
