Had a great conversation with a normie who understood #bitcoin very well. The only thing he was scared about is that when quantum computing hits, it might destroy the concept of hashing and securing it.

I don’t know enough about quantum computing but would like to continue this conversation soon. Could it be an actual threat? Any research or articles that cover this potential threat including that I can share about that? I feel he was nearly there, but this really held him back. He is very technical and knows his stuff.

You have to remember as computer systems develop so do ways to circumvent issues regarding Bitcoin. The protocol will adapt accordingly

This was basically my answer since I don’t know enough about the topic, but didn’t feel satisfying. Would like to really see the ups and downs

The factor keeping quantum out of taking down the network is room temperature semiconductors. Quantum computers generate a lot of heat and consume a lot of energy. A coordinated quantum attack on every computer running a bitcoin node would be what would change the bitcoin code and have it work. So basically many quantum computers on every internet network in the world where bitcoin is running. It’s not possible because both governments do not trust each other, And that level of quantum computing is not available in all parts of the world. But a quantum computer brute forcing one wallet that is pretty easy. For your wallet to be targeted specifically it would need someone to really attract a lot of attention from someone with access to a quantum computer and who would be willing to use it nefariously, So it would be a pretty specific situation. Quantum computers are for solving problems like how much rocket fuel you need to get to mars, Not cracking bitcoin wallets. Besides this the fact that banks hide trillions of dollars offshore for drug cartels is a more obvious and easy to prove catch of criminal behavior than money hidden in bitcoin.

You can't magically change the laws of #physics or #mathematics. You can't reorganize randomness without following the laws of mathematics and physics.

Chaos is the solution to the unified field theory. Quantum computers won't change these facts. All they can do is crunch the numbers faster. You can always up the numbers by orders of magnitude, and then hash that.

Cryptography is beautiful..🧡😊

It doesn't affect hashing it breaks ECC

Not to mention that if QC's hash better faster stronger cheaper then miners will buy and use them to SECURE the BTC network!

A question I have in mind since the very beginning.

And I have never find any convincing answer to it...

Really curious to have any take on the matter!

An amusing take from someone who is known for being true to science:

Symmetrical cryptography seems unaffected, but asymetrical cryptography looks like it does. So the public key private Key cryptography will be broken, the one from which you sign your transactions. Idk how they are gonna solve that. But there probably are solutions to this.
