The cryptocurrency world regularly sees headlines predicting the end of Bitcoin due to quantum computers. But are these fears justified? Google’s recent achievements with its quantum processor “Willow” make us wonder how close we are to a real threat to the world’s most important cryptocurrency.
🔬 Quantum Computers: What Are They and Why Are They a Concern?
Quantum computers are computing devices that use the principles of quantum mechanics to solve complex mathematical problems at lightning speed. In theory, they can perform parallel calculations that would be impossible for classical computers.
What does this mean for Bitcoin?
Bitcoin uses the SHA-256 algorithm to secure transactions and generate new blocks on the blockchain network. This process is called “mining” and is secured against attacks thanks to its immense mathematical complexity, which requires enormous computing power.
🚨 Can Quantum Computers Crack Bitcoin?
According to research, to break the SHA-256 algorithm in less than an hour, a quantum computer would need to have at least 317 million qubits. Currently the most advanced quantum processors, such as Google Willow (105 qubits) i IBM Eagle (127 qubits), are still far from this value.
Example:
It's like trying to drill into a bank vault... with a plastic spoon. The difference between 105 qubits and the required 317 million is astronomical.
🔒 Why Is Bitcoin Safe (For Now)?
- Current State of Technology:
Current quantum computers are too primitive to harm Bitcoin. Although quantum technology is developing at a rapid pace, the road to creating a device capable of breaking the blockchain remains long. - Progress in Cryptography:
The Bitcoin development community is aware of the potential threat and is already working on algorithms resistant to quantum computers, such as:- Supersymmetric cryptography
- Post-quantum algorithms (e.g. RSA-4096)
- Blockchain Flexibility:
The Bitcoin protocol is a “living” ecosystem. In the event of a serious threat, it could be shut down updated for additional security.
🔭 What Do the Experts Say?
Scott aaronson, professor of theoretical physics at the University of Texas:
“Quantum computers are the future, but destroying Bitcoin is far beyond their reach. Current achievements are just the tip of the iceberg.”
Vitalik Buterin, creator of Ethereum:
“Anyone concerned about the future of cryptocurrencies should focus on innovation rather than fear. Bitcoin and blockchain will survive by adapting.”

🤔 Should I Invest in Bitcoin? My Opinion
Would I buy Bitcoin in the face of quantum computers? Tak.
Grounds:
✅ Quantum computers are still a long way from being able to crack Bitcoin.
✅ The blockchain industry is developing dynamically and is ready to adapt.
✅ Fear of quantum technology is overrated – most reports are clickbait.
📊 Summary: What Does the Future Bring?
Although quantum technology offers great opportunities, it will not pose a direct threat to Bitcoin for a long time. The key will be development of quantum cryptography and blockchain protocol improvements, which will help protect the system against potential attacks.
