Bitcoin's Real Quantum Danger: Your Wallet, Not the Network

Stop worrying about mining. Quantum computers will steal your Bitcoin directly from dormant wallets first. See which addresses are the first prey.

BTQ Technologies Corp. recently published an important research paper that reveals the physical and economic reality of the use of quantum computers in the Bitcoin network. 

The study, titled "Kardashev Scale Quantum Computing for Bitcoin Mining", straightens public concerns about the future of the crypto asset.

Although quantum computers are often perceived as a threat to networks, this research reveals that using such technology to speed up traditional mining is impossible at the moment.

According to study author Pierre-Luc Dallaire-Demers, competitive quantum mining requires unusually large resources.

Based on the difficulty of Bitcoin in January 2025, a fleet of quantum computers would require approximately at the difficulty of Bitcoin as of January 2025, a quantum fleet would require approximately 10 to the power of 23 physical qubits and 10 to the power of 25 watts.

To give you an idea, the energy requirement is close to the total power output of a star. 

This makes quantum mining far beyond the current capacity of human civilization.

The Real Threat: Digital Signature Vulnerability

The study clarifies a common misconception in the crypto industry. If many people are concerned about "quantum-accelerated mining," the research confirms it's a dead end when it comes to calculating real-world hardware and energy costs.

A much more pressing threat is the vulnerability in Bitcoin's digital signature. This is what is called the real "cryptographic crisis".

"To push mining toward a significant consensus effect, one must deploy astronomical quantum fleets with energy scales well above those of current civilizations," Dallaire-Demers said. "The real cryptographic crisis is signature vulnerabilities, and that time bomb is already under way."

Building a secure future of quantum

The findings underpin BTQ's efforts in developing "quantum Bitcoin", a special architecture to protect the network from future quantum attacks. 

The main focus is on strengthening the authentication layer through post-quantum cryptographic standards, such as the NIST standard signature and the “Pay-to-Merkle-Root”model.

In addition to security, this research reinforces the reason for using Quantum Proof of Work (QPoW). In contrast to forcing quantum hardware to perform classical mining, QPoW is designed specifically for quantum machines.

The Model shows that a quantum miner consumes only 0.25 kWh in 10-minute intervals, compared to 390 kWh in a classic machine, being an energy advantage of up to 1,560 times.

Bitcoin's current security mechanism relies on an algorithm called Elliptic Curve Digital Signature Algorithm (ECDSA). This algorithm ensures that only legitimate owners of private keys can spend their Bitcoins. In a conventional computer world, hacking these keys would take billions of years.

However, quantum computers work on a different principle through the phenomena of superposition and entanglement. With specialized algorithms such as Shor's algorithm, quantum computers in the future could theoretically crack the encryption used by almost all digital infrastructures today, from banking to crypto wallets.

The emergence of research such as that conducted by BTQ Technologies becomes very crucial for the sustainability of digital assets. The focus of the industry is now starting to shift from just transaction speed performance to "quantum Readiness".

The move aims to update Bitcoin's underlying protocol before a sufficiently powerful quantum computer is actually created, to ensure the world's digital wealth remains safe from future technological threats.
