sure they came up with that garbage reasoning later

"we'll simulate quantum physics with quantum physics"

that doesn't sound like a computer to me, it's like me saying my kitchen is a food computer with which I can simulate the act of making food

that's not what any of these researchers are focusing on, that's not what gets them excited, they're focusing on shor's algorithm

no, they did not come up with it later.

insane amounts of money was being invested into quantum computing far before Bitcoin existed. Shor discussing his algorithm for factoring cryptographic keys in the context of quantum dates back to the mid nineties. The first demonstration of an actual physical implementation of quantum was over a decade before Bitcoin, and it was for search regardless, not breaking signatures. The whole universe does not revolve around Bitcoin and all of this work began a couple decades before the genesis block.

lol exactly. thank you

the axiom 4d ago

still you must recognize that the food computer analogy was good

leave a like if you agree

thanks

its not a general purpose computer no, its a specialized tool for doing very specific things with limited use cases. you won't be gaming on your quantum pc anytime soon

the main reason is that computing with physics is really difficult.

create a quantum algorithm is like trying to build a program that consists of throwing stones into a pond and trying to encode the answer in the constructively interfering waves.

that's why there are only like 5 discovered algorithms (limited use cases).

i honestly had no idea how shor came up with it. i mean if you just look at him he's a giga nerd.

That being said, your concern is slightly legitimate. A lot of focus *is* being given to Shor over other algorithms and potentially making money off of Bitcoin derivatives markets is a major part of that motivation. Which is exactly why we need to start taking this seriously and have planned quantum resilience baked into Bitcoin. I’d like to see FIPS-204/205 and eventually 206 when it becomes solidified as a standard be made into wallet formats. So that I can have an n-in-n multisig with taproot and all the new algorithms for my life savings, in hopes that at least one will remain invulnerable through the coming era.

If you are right and quantum never materializes as a threat to elliptic curves, we will have accomplished less, but it will be at least enough for my peace of mind (I have 90% of my net worth in Bitcoin) and it will also let the general market see in the interim that Bitcoin developers and the community have taken potential threats seriously.

If you are wrong and Bitcoin breaks elliptic curves, then we will have saved everything my children are going to inherit.

makes sense, I may agree

on an related topic, what do you think of moving to zcash? they're quantum resistant, scalable and fully private, it sounds like the bitcoin ideal

I'm not a zcash shill and don't own any, was just thinking

weev 4d ago

zcash is not fungible
