Quantum computers are considered one of the most promising technologies of the future. They promise computing power far beyond that of classical computers. However, this revolution could also pose a threat to modern cryptography—and thus to systems like Bitcoin.
The critical question is: Can quantum computers break Bitcoin? And if so, will Bitcoin need an upgrade?
How Quantum Computers Threaten Cryptography
The security of modern cryptography relies on mathematical problems that are difficult for classical computers to solve. Bitcoin primarily uses two algorithms:
1. SHA-256 (for hash functions)
2. ECDSA (Elliptic Curve Digital Signature Algorithm, for digital signatures)
Quantum computers could specifically attack ECDSA using Shor’s Algorithm, which can break elliptic curve cryptography. In theory, this would allow an attacker to derive private keys from public addresses—a nightmare scenario for Bitcoin.
Does This Also Affect SHA-256?
Fortunately, SHA-256 (and similar hash functions) are only minimally vulnerable to quantum attacks. Grover’s Algorithm could theoretically cut search times in half, but even then, attacking Bitcoin mining or transaction hashes would be extremely resource-intensive.
Is Bitcoin Really at Risk?
The good news: Not anytime soon.
1. Quantum computers are not yet powerful enough
- Current quantum computers have only a few error-prone qubits.
1. Breaking ECDSA would require thousands of error-corrected qubits—something that is still years or decades away.
2. Bitcoin transactions are often "quantum-resistant"
- As long as Bitcoin addresses are used only once (as recommended), the risk is low.
- Only publicly known addresses (e.g., unused funds in old wallets) would be vulnerable.
3. The community can adapt
- If quantum computers become a real threat, Bitcoin can upgrade to quantum-resistant cryptography (e.g., Lamport signatures or lattice-based cryptography).
Will Bitcoin Need an Upgrade? Long-term: Yes.
Once quantum computers become practically viable, Bitcoin will need to update its signature algorithms. However, progress is slow enough that the community will have time to respond.
Possible Solutions:
- Post-quantum cryptography (e.g., XMSS, SPHINCS+)
- Schnorr signatures (already part of Bitcoin’s protocol, offering better scalability and serving as a foundation for quantum-resistant upgrades)
- Hybrid systems (combining ECDSA with quantum-resistant signatures)
Conclusion: Bitcoin is (Still) Safe
Quantum computers pose a potential threat, but not an immediate one. Bitcoin developers have time to prepare, and promising quantum-resistant solutions already exist.
Bitcoin won’t be cracked overnight—but the community must stay vigilant. Once quantum computing makes significant advances, an upgrade will be necessary. Until then, the network remains secure.

Bitcoin, a cryptocurrency, relies on cryptographic algorithms to ensure its security. However, the emergence of quantum computers poses potential threats to Bitcoin's security protocols. In this article, we'll explore the likelihood of quantum computers hacking Bitcoin and the future of cryptocurrencies.
Bitcoin's Security Protocols
The Bitcoin network uses SHA-256 hash function and Elliptic Curve Digital Signature Algorithm (ECDSA) to secure transactions. These algorithms are considered difficult to break for current classical computers.
Capabilities of Quantum Computers
Quantum computers operate using quantum bits (qubits) and can perform computations by leveraging quantum mechanical properties such as superposition and entanglement. This enables them to calculate multiple possibilities simultaneously, potentially solving certain problems much faster than classical computers.
Quantum Computers and Cryptography
Quantum computers, particularly through the use of Shor's Algorithm, could have superior abilities to factor large numbers into prime factors. This poses a threat to cryptographic algorithms like ECDSA, which rely on prime factors.
Bitcoin Network's Resilience to Quantum Attacks
Currently, it's too early to discuss the practical existence of a quantum computer. However, if such a computer is developed in the future, the Bitcoin network would need to update its security protocols. Transitioning to post-quantum cryptography could be a solution.

While quantum computers theoretically have the potential to hack Bitcoin, practical implementation of this technology is not yet available. Bitcoin and other cryptocurrencies continue to work towards enhancing their security against future threats.

🔐 The future of Bitcoin and digital security might be under threat much earlier than many anticipated. Google has revealed that recent breakthroughs in quantum computing could significantly reduce the resources required to crack the encryption protecting crypto wallets and sensitive data.

⚠️ Quantum Leap: From 20 Million Qubits to Under One Million
Craig Gidney, a quantum researcher at Google, stated that factoring a 2048-bit RSA key — one of the core cryptographic standards — may no longer require 20 million qubits, as he estimated in 2019. Instead, it could now be achieved with fewer than one million qubits in under a week.
This leap is possible thanks to:

🔹 advanced quantum algorithms,

🔹 improved error correction techniques,

🔹 and denser qubit encoding that allows for more efficient operations.

⚡ Willow Chip Solves "10 Septillion-Year" Problem in 5 Minutes
In December 2024, Google unveiled its new quantum chip Willow, capable of solving a problem in five minutes that would take traditional supercomputers 10 septillion years. Critics quickly raised alarms, suggesting that such power could potentially rewrite the Bitcoin blockchain or even access dormant wallets, including those possibly linked to Satoshi Nakamoto.

🧠 What This Means for Crypto Security
Bitcoin uses elliptic curve cryptography, which is mathematically similar to RSA. If quantum computers can crack RSA faster than expected, Bitcoin's security timeline might have just shortened significantly.
Google warned that some state actors or tech rivals might already be collecting encrypted data now to decrypt later when quantum machines become viable.

🧪 Magical States and Quantum Efficiency
Google researchers also employed so-called T-states (magical quantum states) to boost computing power without increasing system load. This technique allows for more efficient operations, saving time and physical space.

🔎 Project 11: Quantum Bounty on Bitcoin Security
Meanwhile, Project 11, a quantum research group, has offered a $85,000 bounty to anyone who can break a simplified version of Bitcoin's encryption using a quantum computer. While the test targets short key lengths (1 to 25 bits), far below Bitcoin’s 256-bit standard, it helps assess how urgent the quantum threat really is.
The group argues that Shor’s algorithm, a key quantum technique, could eventually break Bitcoin’s elliptic curve encryption altogether.

📅 Timeline: Is 2030 Too Late?
The U.S. National Institute of Standards and Technology (NIST) recommends phasing out vulnerable systems starting in 2030. But Google’s findings suggest this timeline may be too conservative.
Tech giants are already making moves:

🔹 IBM aims to build a 100,000-qubit quantum computer by 2030

🔹 Quantinuum plans to deliver a quantum-secure system by 2029

🧩 Bottom Line: Bitcoin Is Safe… For Now — But the Clock Is Ticking
Google reassures that user digital assets are currently safe. However, the trajectory of quantum progress is undeniable. The crypto industry must start preparing now if it hopes to remain secure in the quantum age.
