Fireblocks CEO Michael Shaulov this week dismissed the idea that quantum computing poses an insurmountable technical threat to Bitcoin. Instead, he framed the biggest obstacle as a human one: getting the network's sprawling set of stakeholders to agree on a new cryptographic standard.
Not a technical problem
Speaking on the record, Shaulov called the transition to a post-quantum signature scheme 'not a technical challenge' for Bitcoin. The core engineering, he argued, is straightforward. The real difficulty lies elsewhere.
The coordination hurdle
'It's mostly a coordination issue,' Shaulov said. Bitcoin has no central authority. Upgrading the cryptography that secures every transaction requires broad consensus among miners, developers, exchanges, and node operators. That's a political and logistical puzzle, not a code problem.
What quantum means for Bitcoin
Quantum computers, once sufficiently advanced, could theoretically break the elliptic-curve signatures that Bitcoin uses today. That would let an attacker forge transactions and drain funds. The threat has been discussed for years, but until now most of the focus has been on when the hardware will arrive — not on how the network would respond.
Shaulov's comments shift the conversation. If the fix is technically simple, the clock is ticking on governance, not cryptography.
Who has to move
A post-quantum upgrade would touch every wallet and every validating node. Developers would need to agree on a new signature algorithm. Miners would need to signal support. Exchanges and custodians — including Fireblocks — would have to update their systems. The coordination task is enormous, even if the math is not.
No timeline yet
Shaulov did not offer a deadline for when such a change might happen. The Bitcoin community has a history of slow, deliberate upgrades. The question now is whether that pace is fast enough to outrun a technology that is advancing quickly. Whether the network can coordinate in time is an open question.
