⚡️ Adam Back exposes one of the biggest myths in the crypto world: the quantum computing scarecrow
A tip for conspiracy theory promoters:
Bitcoin does not use encryption. Learn the basics first, or this reveals your ignorance."
This sentence
is an accurate diagnosis of a serious cognitive flaw widespread in the crypto community.
Let's analyze it deeply.
First: What does Adam Back mean when he says "Bitcoin does not use encryption"?
Most people confuse 3 different concepts:
1. Encryption
2. Hashing
3. Digital Signatures
Bitcoin does not use traditional encryption
There are no "encrypted" data in Bitcoin that can be decrypted by a quantum computer.
Bitcoin relies on:
SHA-256 (hashing, not encryption)
ECDSA (digital signatures, not data encryption)
And this is a fundamental difference that most conspiracy theory promoters "quantum computers will break Bitcoin" do not understand.
Second: Why do quantum computers not break Bitcoin as promoted?
1️⃣ SHA-256 (hashing)
Even quantum computers:
Cannot invert the hash
Cannot extract private keys from the hash
The most they can do is accelerate probabilistic search only
And the result: breaking SHA-256 quantumly requires energy and resources exceeding the total Earth's production.
2️⃣ ECDSA (digital signatures)
Yes, theoretically:
A very powerful quantum computer could break exposed public keys
But here is the surprise no one mentions:
🔴 In Bitcoin, the public key is only exposed at the moment of spending
Meaning:
You have a very short time window
You need a hypothetical quantum computer
At the same moment
And on a global decentralized network
This is not a practical threat but only a theoretical scenario.
Third: The truth no one talks about
If a quantum computer capable of breaking Bitcoin appears:
Banks will collapse first
SSL/TLS will fail
Military systems will collapse
Satellites will malfunction
Global markets will freeze
Bitcoin will be the last problem
And most importantly: Bitcoin can be upgraded with quantum-resistant algorithms, unlike traditional centralized systems that are not easily changeable.
Fourth: Why is this "quantum computer" theory promoted in the first place?
🔹 To scare new investors
🔹 To undermine confidence in an asset that cannot be controlled
🔹 To justify alternative centralized projects
🔹 To show a false "technological superiority"
That’s why Adam Back said:
Get your basics right or it's a tell
Meaning: your ignorance of the fundamentals exposes you.
The strategic conclusion (and here is the real distinction):
Bitcoin was not built by chance
Its algorithms were chosen for long-term flexibility
Quantum threats have been known for over 20 years
And have been taken into account from the beginning
🧠 Quantum computers are not a threat to Bitcoin but a new test, and Bitcoin is designed to adapt.
The question that breaks the comments:
If quantum computers will break Bitcoin, why haven't we seen any entity use them to break:
Banks?
SWIFT?
Visa?
Military systems?
