Just had a thought.. If we don’t update bitcoin to post quantum cryptography before it happens, it’s all gone. Our secret keys *are * our identity. There is no hard form that returns our money. Is this true? #asknostr #bitcoin #quantum

Yes. This was one reason I almost did not get into Bittie or any other crypto. People need to be serious about this.

Google has switched Chrome over to a quantum resistant hybrid of Kyber-768 and X25519.

This is a sign that this is a puck to skate in front of.

“Bitcoin fixes this…” will sound moronic if a slew of funds starts to disappear and people see that this is no joke.

At the same time, quantum has been sooning so long I understand why people have a hard time taking it seriously.

But Google has changed over, and they are not the only group concerned with this.

It’s a current focus at NIST, and advances come to light so frequently in this domain that we need to start hardening against quantum.

That is my opinion and I’m curious to hear what others think.

Thank you.

When you say a “slew of funds” are you meaning to say won’t be all UTXOs, all at once?

Things I’ve seen, like Shor’s algorithm, have a better chance of finding, say, the private key for any given SHA-256 public key. AFAIK it would not mean they would get the whole rainbow table made GGEZ all at once. More like there’s more of a chance to not strike out all the time so bad when looking for needles in haystacks of haystacks of haystacks due to being able to harness qubits to bring factorial time complexity down to polynomial time

When it first starts to be compromised, I think it is likely it will maybe it will be possible to spend a not prohibitive amount of time compromising one address… let’s say a year. Then as things get more and more sophisticated the whole shebang is completely compromised.

The timeframe is usually 10-20 years from now when you hear security researchers mention the horizon.

I prefer pessimistic and consider that safety is more likely 2-5 years with great confidence and reassess based on current news at regular intervals.

I doubt criminals to be the first people to have their hands on quantum computing.

First will be scientists. They will let the world know that hash was broken.

Bitcoin price will go down a bit.

We will upgrade the network and everything will be fine.

That’s my guess.

It’s likely to be classified first. Likely that it could be compromised and nobody besides a select group will know.

It will be SIGINT. They will tell no one for as long as they can. They may already have a back door. That is their job.

info out that the us gov compromised kyber

Backdoors in cryptography are a perpetual us gov fixation…. From The Clipper Chip to Diffie-Hellman
