The debate around Bitcoin’s long-term security has taken center stage once again, this time with strong warnings from Solana (SOL) co-founder Anatoly Yakovenko. Speaking at the All-In Summit 2025, Yakovenko stressed that quantum computing could pose a significant challenge to Bitcoin within the next decade — perhaps as soon as 2030.
“A Quantum Breakthrough Could Happen in Five Years”
Yakovenko estimated that there’s a 50% chance of a major leap in quantum computing power within the next five years. Drawing parallels to the rapid acceleration of artificial intelligence, he argued that technological progress may come much faster than most expect.
“Bitcoin should migrate to a quantum-resistant signature scheme,” he urged, noting that waiting too long could leave the network vulnerable at a critical time.
Why the Quantum Threat Matters
Bitcoin’s security is built on the Elliptic Curve Digital Signature Algorithm (ECDSA). This cryptographic method relies on the difficulty of solving the elliptic curve discrete logarithm problem — something classical computers cannot do efficiently.
Quantum computers, however, are theoretically capable of breaking this system, undermining the foundation of wallet security and transaction validation.
This concern isn’t exclusive to Yakovenko. Earlier this year, Naoris Protocol founder David Carvalho warned that advanced quantum machines might crack Bitcoin’s current encryption in less than five years.
The Challenge of Making Bitcoin Quantum-Resistant
In theory, Bitcoin could adopt quantum-resistant cryptography. But doing so would require a hard fork, one of the most contentious and disruptive types of upgrades in blockchain systems.
Given Bitcoin’s conservative culture and the community’s hesitancy toward drastic protocol changes, implementing such a transition would be politically and technically complex.
Divided Opinions in the Bitcoin Community
While Yakovenko and others push for urgency, not everyone in the Bitcoin ecosystem agrees.
-
Adam Back, CEO of Blockstream, believes existing quantum computers don’t currently threaten Bitcoin, though he admits they could in the long run. In his view, it would likely take at least two decades before quantum machines reach a level where they endanger the network.
-
Samson Mow, founder of Jan3, takes a similar stance. He acknowledges the risk but argues it’s still far in the future: “This is a real risk, but at least a decade away. Many other systems will fail before Bitcoin does.”
