Bitcoin Quantum Threat Could Arrive Before Networks Are Ready, New Report Warns

A new report has raised concerns that Bitcoin and other digital assets may not be fully prepared for the growing threat posed by quantum computing. According to researchers, the timeline for upgrading crypto systems could be much slower than the pace at which quantum technology is advancing.

Quantum Computing Could Put $3 Trillion in Digital Assets at Risk

A 110-page report from Project Eleven warns that more than $3 trillion in digital assets secured through elliptic curve cryptography could eventually become vulnerable to quantum attacks within the next four to seven years.

The report argues that a potential “Q-Day” — the moment when quantum computers become powerful enough to break common public-key encryption could happen as early as 2030 and no later than 2033.

Researchers explained that Bitcoin, Ethereum, stablecoins, and many digital systems rely on elliptic curve digital signatures, which could become vulnerable if advanced quantum computers successfully apply Shor’s algorithm to derive private keys from public addresses.

Bitcoin Migration to Quantum-Resistant Security Faces Challenges

The report warns that moving Bitcoin to post-quantum cryptography may take years because upgrades on decentralized networks require broad coordination between users, exchanges, custodians, wallet providers, and miners.

Project Eleven noted that large technological transitions often take between five and ten years, while Bitcoin upgrades have historically moved slowly and faced disagreements within the community. Researchers compared the challenge to Bitcoin’s SegWit upgrade, which took more than two years and resulted in network division.

Banking and Military Systems Also at Risk

The report emphasized that quantum computing is not only a crypto issue. Banking systems, cloud networks, authentication services, and military communications also depend on the same encryption methods, increasing concerns about global cybersecurity readiness.
