VanEck Head of Digital Assets Research Matthew Sigel said in a CNBC interview that the Bitcoin community now recognizes quantum computing as a real security risk, even though current quantum machines are not capable of breaking Bitcoin’s cryptography.

Sigel said the challenge is being taken seriously inside the Bitcoin ecosystem, with some developers already testing quantum-resistant signatures on live sidechains. He said the community understands the scale of the problem and is bringing together technical talent to work on upgrades.

He also said Bitcoin’s decentralized governance makes any major security transition slower than in centralized systems. Unlike a company-controlled network, changes to Bitcoin require broader coordination among developers, infrastructure providers, and users, which can extend the timeline for deployment.

According to the interview, no existing quantum computer can currently break Bitcoin’s cryptography. The concern is tied to future advances that could eventually threaten signature schemes used across the network. Sigel framed the issue as one the industry has time to prepare for, rather than an immediate failure of Bitcoin’s security model.

The report also pointed to ongoing work by major industry players. Coinbase said in July it planned to implement a post-quantum signing pipeline using secure enclaves and threshold cryptography. The article further said a Bitcoin Security Consortium formed in July, with participants including BlackRock and Fidelity Digital Assets, to fund open-source work tied to proposals such as BIP-360. Different sources describe the matter differently, and the relevant details still require official confirmation.

Why It Matters

Quantum risk is moving from a theoretical talking point to a technical and institutional planning issue for Bitcoin. That matters because Bitcoin’s security assumptions sit at the base of exchange custody, ETF exposure, payments infrastructure, and long-term treasury use. If the industry treats post-quantum migration as a shared infrastructure task early, it reduces the chance that future hardware breakthroughs turn into a disorderly governance event.

The discussion also highlights a broader market-structure point: Bitcoin’s resilience depends not only on code, but on how quickly wallets, custodians, miners, and large financial firms can align on upgrades. That makes post-quantum readiness a coordination question as much as a cryptography question.
