Quantum computing power and interledger security

Recommended Posts

Hi there I see a failure in the ledger system for Blockchain if and when quantum computers are being used to hack the system. We already know that quantum computers have been used to hack unhackable systems with ease. The question i  have is there any partnerships being setup with XRP and a quantum technology security protocol company to  built on top or embedded into the Blockchain to remove the threat of quantum computer attacks.

I heard David Schwartz talk about research in making the ledgers quantum proof in his last interview, and they had some solutions in mind but not viable yet.

You say there have been quantum attacks on systems before, but as far as I know there arent any 'real' quantum computers yet right? Just some quantum mimmicking ones like D-Wave systems. Or did I miss something big?

David had mentioned quantum computers hacking blockchain. I believe the answer was that what exists today is in its infancy, and if they implement the measures now then they would essentially have to support protection forever. So they are going to wait until there is a real need for it or the design of quantum computer counter measures have the elegance that is worth supporting.

IBM’s new quantum computer is a symbol, not a breakthrough

If Quantum Computers become an issue. We would have way bigger problems on our hands. If they were able to be used to hack a block chain or distributed ledger that would mean IT security for every bank, every system in this world would be screwed. Quantum Hacking would be the enemy to everything besides using a pen and paper. It wouldn’t be limited to just Blockchain/Distributed Ledger, EVERYTHING would be Fu#$%^ if in the wrong hands. I’m going to trust JK on that things are not there yet, and if that issue ever became a possibility I’m sure that he and every other genius would find a way to protect everything.

Ive seen this discussed outside of the Ripple/crypto sphere and the answer is to simply make the computational space that needs to brute force a key bigger.

This makes sense because the problem you are talking about comes from the fact that quantum computers can search a much larger computational faster than classical computers can.

These quantum technology security protocol companies are popping up all over the place. Huge use case right now.

Yet there's just the round 2 for post-quantum cryptography announced: https://csrc.nist.gov/projects/post-quantum-cryptography/round-2-submissions

I really don't see what these companies would reasonably do other than charging money for snake oil.

Meh.  Quantum computing today is still long on hopium and short on results.

"All we have to solve to have a functioning quantum computer is to eliminate quantum decoherence"  <--->  "All we have to solve to have effective superconductors is to have them work at room temperatures" <--> "All we have to solve for a functioning cold fusion device is to overcome nuclei repulsion without injecting massive amount of energy" 

Yup.  Super simple.  Go get 'em! 

I look forward to advanced AI powered by quantum computing and enabled by superconductivity discovered by that same AI and powered by cold fusion which that AI also subsequently solved.

Only a very select few of company's have them. 

As of June 2018, public records suggest there are eleven Quantum Computers.

 

Quantum Computers will be out in 20 years. 

Still loads of testing to be done.

No where near ready. 

 

You say they have been used for hacking?  Please give a source.
