Google’s newly announced quantum computing breakthrough, the Willow chip, is sending shockwaves throughout the tech world, and it has fresh concerns in the crypto community about Bitcoin’s security.
On December 9, Google CEO Sundar Pichai unveiled Willow, which boasts a powerful 105 qubits. This chip is meant to perform complex calculations at lightning speed. In fact, it cracked a problem in just five minutes that would take traditional supercomputers billions of years to solve.
This leap in quantum computing is seen as a huge milestone, and it could change industries ranging from drug research to energy development.
However, with the potential of Willow, many in the crypto world are raising questions on the future of Bitcoin’s cryptography. Most people feel that quantum computers may one day break Bitcoin’s encryption and put it at risk. Others claim that Willow’s 105 qubits may just make that a reality sooner rather than later.
According to Cochran, the crypto industry has a shorter timeline—less than 10 years—to address quantum computing risks before they become a pressing issue. He stated:
“With one breakthrough we’ve seen a 20-year drop in how long Bitcoin and other cryptocurrencies have to start taking post-quantum encryption seriously. And another breakthrough of this equivalent size would put those issues on our doorstep in no time.”
But the leading experts, including Emin Gün Sirer, founder of Ava Labs, have reassured the community. While Willow is impressive, it’s still far from being able to break Bitcoin’s security. Bitcoin’s encryption is based on robust algorithms like SHA-256 and ECDSA, which would require a quantum computer with millions of qubits to crack—well beyond Willow’s current capabilities.
Furthermore, Satoshi Nakamoto, the creator of Bitcoin, also predicted the quantum threat. Satoshi even had a plan for updating Bitcoin security, in case it would require such a thing; one that the system might simply switch to a new cryptographic algorithm by soft fork, thus leaving its users enough time for upgrading.
For now, Bitcoin is secure. Willow is a large advance in quantum computing, but there’s still a long time until it can be anything even remotely threatening to Bitcoin. Experts are urging the crypto community to keep an eye on progress and take proactive measures. Nevertheless, there is no current call for panic. With that built-in resilience, Bitcoin had always anticipated future problems—it’s quantum or just generally.
