Key Takeaways:
- Microsoft’s Majorana 1 chip may accelerate the need for Bitcoin’s quantum resistance, with River estimating a potential impact by 2027-2029.
- Quantum threat timeline debate continues, as skeptics argue financial institutions would be targeted before Bitcoin.
- Early preparation is crucial, with River’s CEO urging discussions on quantum-resistant solutions well before the threat materializes.
Microsoft’s newly introduced quantum computing chip, Majorana 1, could accelerate Bitcoin’s transition to quantum-resistant security, according to Bitcoin exchange River.
The chip, unveiled on February 19, signals Microsoft’s growing presence in the quantum computing space, alongside competitors like Google, which introduced its own Willow chip in December.
1 million qubits can potentially crack a Bitcoin address.

Microsoft says its new chip creates a path to get there.
How long does Bitcoin have to become quantum-resistant? And what’s actually at risk?

River highlighted in a post on X that while a quantum computing breakthrough capable of breaking Bitcoin’s cryptographic security is still years away, Majorana 1 may have shortened that timeline.
The exchange estimates that a 1-million-qubit quantum computer, potentially achievable by 2027-2029, could theoretically crack Bitcoin addresses if run for several days or weeks.
Despite these concerns, some experts argue that fears about Bitcoin’s vulnerability to quantum attacks are exaggerated.
A quantum computer powerful enough to compromise Bitcoin would likely be more valuable in attacking traditional financial institutions, which hold significantly more assets—$188 trillion globally compared to the $3.2 trillion cryptocurrency market.
Regardless of the uncertainty, River’s CEO, Alexander Leishman, stressed that discussions on making Bitcoin quantum-resistant should start now.
While the threat may still be distant, early preparation is key to ensuring Bitcoin’s long-term security against future quantum advancements.
