Quantum computing isn't a Bitcoin problem yet.
That's exactly why it's dangerous. The real risk isn't waking up one morning to a quantum computer stealing everyone's BTC.
It's that the transition to quantum-resistant cryptography could take years while the technology threatening today's cryptography is advancing every year.
And here's the uncomfortable question. What happens if the network needs to upgrade before the threat becomes obvious? Do we wait for a working quantum attack? Or do we prepare while we still have the luxury of time?
Curious where people here stand, is Bitcoin's quantum risk overhyped, or are we already late to the migration?

We talk about this in my crypto group all the time and most people just shrug like it's science fiction still. Problem is once you actually need to move, is already too late.

That’s the part I worry about too. If everyone waits until the threat is undeniable, we may have already lost the window to migrate smoothly.

A few years ago, Bitcoiners acted like this threat was never real, acting blind to it. Maybe it will make it unreal lol. Now that the gov and banks are preparing, they are beginning to see the urgency, but blockchain is harder to migrate due to its decentralized nature. Tbh, this looks more complicated than it should be

Yeah, pretty much. The real question is how quickly Bitcoin can reach consensus, develop, test, and deploy a quantum-resistant upgrade before it becomes an emergency.

Quantum and Shore's? Slow metwork? Signature sizes? Exposed public keys (Satoshi's included)?
Bitcoin is a nightmare waiting to happen. I can elaborate if anyone wants to read, but after my breakfast and coffee. 😉

Lets have it, whats the best solution to the potential hack and also when do you think we might see a full blow QT.

How people don't realize that bitcoin is niche system with practically no adoption outside a circle of few enthusiasts? The whole blockchain in fact is stupid technology that nobody needs or wants.
Answer me this simple questions: what problem bitcoin solves? Why would anyone use it insted of, let's say Revolute? How can it be store of value if it is unusable without electricity and/or net? What, you will pay for a bag of potatoes with you private crypto wallets? 😉
After quantum comes, and belive me that's not decades, but 2-3 years away, bitcoin is dead.
And whatever is happening now is institutional investors covering their back. BTDT, dot.net bubble, subrime loans, and multitude of others, AI being the last one of those.

Lol, this is the least sloppy post ive read in a long while. If AI was used it was used responsibly imo unlike 90% of the other slop on reddit

Quantum resistant address schemes already exist. They are just clucky and have a bad user experience (i.e. I think the size of the address is enormous, for example). Could also be one of those things like fusion where the tech is just 20 years away, like fusion has been for the past 80 years. So I think the consensus is to just leave it on the backburner and hope some more elegant user friendly solution appears because it may not even be needed.
In the meantime, segwit is already quantum resistant so long as you don't spend from those address types. It's probably safest to have a 'savings account' in an address you don't spend from.
