Bitcoin’s security may need an upgrade sooner than many expect, according to Anatoly Yakovenko, co-founder of Solana.
That is the vulnerability Yakovenko highlighted.
Other voices in crypto put the timeline farther out. Reports show Adam Back of Blockstream thinks quantum machines that can threaten Bitcoin are likely decades away — he has cited a figure near 20 years.
Some figures, like Samson Mow, suggest a longer window as well, while newer commentators warn the risk could arrive much sooner if breakthroughs accelerate.
The split in views reflects real uncertainty about when — not whether — quantum will matter for blockchains.
Moving Bitcoin to quantum-resistant signatures is possible, but it is not small work. Based on analysis across industry pieces, such a shift could require major protocol changes, widespread wallet updates, and careful rollout plans to avoid breaking existing addresses or exposing users during the transition.
Some proposals include one-time migration tools and new address types, but none is a simple flip of a switch.
Based on reports, Yakovenko’s main point was urgency: begin testing and building a migration path now, not later.
He noted Bitcoin’s strengths but stressed that preparation would protect users and preserve trust if quantum capabilities arrive faster than many expect.
Industry coverage has already circulated his remarks, prompting renewed discussion across developer forums and research groups.
For now, Bitcoin developers and node operators face a choice between steady, cautious research and faster, coordinated engineering to prepare for several possible futures.
Yakovenko’s estimate — a 50/50 chance in five years — is far from a consensus, but it has pushed the debate back into public view.
