I recently came across an interesting thread where Adam Back, the CEO of Blockstream, revisited the recurring topic of the alleged "quantum risk" to Bitcoin. And honestly, it deserves attention because the guy knows what he's talking about.

For context: Adam Back is not just anyone. He is the creator of Hashcash, a recognized cryptography expert, and has that cypherpunk pedigree that few can boast. Additionally, he exchanged messages with Satoshi Nakamoto, so his perspective on Bitcoin comes from the inside.

What’s interesting is that Adam Back was quite direct this time, basically saying that most of the panic about quantum computers is pure unfounded FUD. His main argument is clear: Bitcoin does not operate with classical encryption in the way fear-mongers try to attack it. So all that talk of "quantum hacking" is based on an incorrect premise.

Adam Back’s critique was blunt: "Bitcoin does not use encryption. If you don’t understand this, you look foolish." It sounds strong, but he’s right at the core. Bitcoin is based on cryptographic hash functions and digital signatures, not on traditional data encryption. The theoretical risk, if any, would be related to old signatures, but even that is speculative.

When asked about realistic timelines, Adam Back was clear: there’s no threat in the short term. Not even in the next 10 years. In earlier estimates, he mentioned a horizon of 20 to 40 years if quantum computers ever reach a practical level that threatens cryptography.

And most importantly, the point Adam Back emphasizes is: the Bitcoin network has time, has the technology, and has the flexibility to adapt long before any real threat materializes. It’s not that they ignore the issue; they understand the true scale of the problem. That’s what differentiates serious analysis from noise.
