 ▲ Bitcoin (BTC), Quantum Computer/ChatGPT-generated image |
Contrary to market concerns that quantum computers could instantly dismantle Bitcoin (BTC)’s security framework, a new analysis suggests that it will likely take at least several decades before any real technological threat materializes.
According to a February 21 report by crypto-focused media outlet U.Today, analysts at cryptocurrency exchange Bitfinex stated in a report that while the threat quantum computers could pose to Bitcoin is real, it is far from imminent. Bitfinex explained that the current level of quantum technology is nowhere near sufficient to break Bitcoin’s elliptic curve cryptography, estimating that computing devices roughly 100,000 times more powerful than those available today would be required. The analysts projected that fault-tolerant quantum computers capable of stably controlling millions of physical qubits are unlikely to emerge before the mid-2030s to mid-2040s.
Another factor easing concerns is that the range of Bitcoin’s security architecture that could be targeted by quantum computers is narrower than many fear. Bitfinex noted that older addresses with exposed public keys or reused wallet addresses could face risks, but most modern Bitcoin wallets use hashed addresses, making it extremely difficult even for quantum computers to extract private keys. Moreover, the Bitcoin network can gradually transition to quantum-resistant cryptographic systems, such as lattice-based cryptography, through soft forks, providing ample time to respond in line with technological advances.
The advancement of quantum computing is not solely an issue for digital assets but one that directly impacts the survival of the global financial system as a whole. If a quantum computer powerful enough to break Bitcoin were to appear, it is more likely that banking systems or government confidential communication networks would collapse before Bitcoin. Bitfinex analysts argued that portraying quantum threats as a fatal flaw unique to Bitcoin is closer to exaggerated fear, emphasizing instead the network’s strong upgrade flexibility.
Within the digital asset ecosystem, research is already actively underway to introduce quantum-resistant signature schemes. Bitcoin developers have laid the groundwork for seamlessly integrating new cryptographic algorithms in the future through upgrades such as Taproot, which is expected to serve as a shield protecting the entire network long before any threat becomes reality. Bitfinex advised investors to place greater trust in Bitcoin’s cryptographic resilience rather than being swayed by unfounded rumors.
Quantum computing represents a long-term engineering challenge for Bitcoin, not a market-destroying black swan event. The Bitcoin community is prepared to preserve its value as digital gold by continuously enhancing security protocols amid technological competition expected to last for decades. As global financial institutions and technology experts collaborate to establish security standards for the quantum era, Bitcoin is also expected to maintain its status as a secure asset in line with the broader evolution of global cybersecurity.
