Quantum computing poses a threat to Bitcoin, but the asset manager VanEck’s Head of Digital Assets Research notes that the community is well aware of the challenge.
During a CNBC interview on Friday, Matthew Sigel explained that although remediation efforts can move slowly due to the decentralized architecture of the cryptocurrency network, participants are actively tackling the problem.
Crypto advocates have previously raised concerns regarding theoretical future breakthroughs in quantum technology that might potentially crack Bitcoin’s underlying cryptography.
Certain industry participants, including various Bitcoin developers, have already initiated preparations for a post-quantum era by experimenting with quantum-resistant signatures across active sidechains.
“It’s a risk,” he stated. “But the community has recognized the scope of the issue. There’s a lot of talent that’s now come together with a framework of how to upgrade the system.”
He further noted: “The upgrades don’t happen as fast because there’s no CEO who can tell the devs, ‘hey, do it now.’ There’s a governance process — it takes more time, it’s a little bit messier, but there are technological paths for quantum resistance, and I think you’ll see more of that over the next couple of years.”
While quantum computers are operational, they are prone to errors, and a machine capable of breaking Bitcoin’s cryptography is not yet a reality. Bitcoin presently stands as the largest computer network globally.
Prominent industry firms—such as Blockstream (a Bitcoin infrastructure company) and Coinbase (America’s leading crypto exchange)—are actively developing remedies.
In July, Coinbase announced its intention to introduce a post-quantum signing pipeline utilizing secure enclaves and threshold cryptography.
Additionally, a Bitcoin Security Consortium comprising BlackRock, Fidelity Digital Assets, Block, and other entities was established in July. The group contributes financial resources and assigns engineers to open-source initiatives supporting measures such as BIP-360, which seeks to add a fresh transaction output type to mitigate long-exposure quantum computing vulnerabilities.
Frequently Asked Questions
Is quantum computing an immediate threat to Bitcoin?
No, a machine capable of breaking Bitcoin’s cryptography does not currently exist, though existing quantum computers are prone to errors.
How is the Bitcoin community addressing quantum risk?
Developers are testing quantum-resistant signatures on live sidechains and major companies are working on technological solutions.
Why do Bitcoin upgrades take time?
Because of Bitcoin’s decentralized nature and governance process, updates take longer since there is no central CEO to direct developers.
What is the Bitcoin Security Consortium?
Formed in July by firms like BlackRock, Fidelity Digital Assets, and Block, it provides funds and engineers to support open-source proposals like BIP-360.
