- Solana’s co-founder Anatoly Yakovenko warns of the potential of quantum technology to disrupt Bitcoin’s cryptographic foundations.
- Yakovenko predicts a 50/50 chance of a quantum breakthrough in five years, urging Bitcoin to shift to a quantum-resistant signature system.
- Quantum computing could potentially crack Bitcoin’s Elliptic Curve Digital Signature Algorithm (ECDSA), exposing Bitcoin’s private keys and destroying blockchain immutability.
At the All-In Summit 2025, Solana’s co-founder Anatoly Yakovenko delivered a striking message that sent ripples across the cryptocurrency landscape. His cautionary words targeted the looming shadow of quantum technology and its potential to shatter the very cryptographic foundations upon which Bitcoin stands. Yakovenko stressed that the timeline for this technological leap might be much shorter than many crypto enthusiasts believe. In his own words:
“I see a 50/50 chance of a quantum breakthrough in five years. Bitcoin should shift to a quantum-resistant signature system.”
This wasn’t just a hypothetical scenario. By comparing the astonishing speed at which artificial intelligence evolved from research papers to real-world tools, Yakovenko emphasized how disruptive technologies can advance faster than anyone anticipates. His bottom line was clear: Bitcoin must act now—or risk being caught unprepared.
The Quantum Threat Explained
To grasp the gravity of Yakovenko’s warning, one needs to understand how quantum computing threatens traditional cryptography. Bitcoin wallets today rely on the Elliptic Curve Digital Signature Algorithm (ECDSA), which is built on the elliptic curve discrete logarithm problem (ECDLP). For classical computers, solving ECDLP is practically impossible—it would take billions of years. But quantum machines could potentially crack these algorithms in hours or even minutes. That means Bitcoin’s private keys could be exposed, leading to catastrophic consequences. Wallets could be drained, transactions manipulated, and the very trust in blockchain immutability destroyed. While many still see quantum computing as “decades away,” cybersecurity researchers insist the timeline could be dramatically shorter.
Experts Say Quantum Might Hit Sooner Than Expected
In June, David Carvalho, founder and chief scientist at Naoris Protocol, echoed Yakovenko’s concerns. He claimed that quantum computers are already strong enough that within five years they could “tear through” Bitcoin’s cryptography. The message from researchers is consistent: don’t underestimate the pace of quantum development. Quantum computing has already made progress in specialized tasks like optimization and simulation. If breakthroughs in error correction or qubit scaling accelerate, the cryptographic shield protecting Bitcoin could be pierced much earlier than the optimistic projections suggest. Yakovenko compared the situation directly to AI:
“It’s shocking how quickly AI went from academic theory to dominating industries. Quantum will not move any slower.”
Why Upgrading Bitcoin Won’t Be Easy
If the threat is so severe, why hasn’t Bitcoin already moved toward quantum resistance? The answer lies in the very structure of blockchain governance. To replace ECDSA with a quantum-safe algorithm, Bitcoin would need a hard fork—a fundamental change to its underlying protocol. Historically, Bitcoin’s community has been extremely resistant to such changes, valuing security, decentralization, and consensus over innovation. A hard fork would require global coordination among miners, developers, and node operators, something notoriously difficult to achieve in the decentralized world. Worse, if consensus isn’t universal, the Bitcoin blockchain could split, creating competing versions of the network. This political and technical barrier means that even if the threat is real, acting fast is far from simple.
Bitcoin Leaders Push Back on the Urgency
Not all Bitcoin leaders share Yakovenko’s sense of urgency. Some argue that quantum computing is still far from practical danger.
- Adam Back, CEO of Blockstream, dismissed the immediate threat. He stated that while quantum computers may one day pose a risk, current machines are nowhere near capable of breaking Bitcoin. According to him, such breakthroughs might only become relevant in “maybe 20 years.”
- Samson Mow, founder of Jan3, echoed a similar sentiment. In an interview earlier this year, he admitted quantum computing is indeed a real risk but insisted the timeline is distant. In his words:
“The danger is likely a decade away. Other systems will break before Bitcoin does.” This reflects a divide in the crypto space. While some push for proactive action, others believe the risk is exaggerated—or at least not urgent enough to warrant the disruption a hard fork would cause.
The debate over quantum computing and Bitcoin’s future is far from settled. On one side, leaders like Anatoly Yakovenko argue for urgent action, warning that the five-year window could be decisive. On the other, established figures like Adam Back and Samson Mow insist the risk is distant, urging caution against overreaction. What’s undeniable is that quantum computing is no longer a distant theory—it is a rapidly advancing technology. Whether it takes five years, ten, or twenty, the day may come when quantum machines can crack Bitcoin’s defenses. And when that happens, the entire crypto world will be tested. The question is not just whether Bitcoin will survive, but whether its leaders and community will have the foresight to act before the storm arrives.
