Quantum Readiness Bill Puts Crypto Encryption Risks Back in Focus

Two U.S. senators have introduced legislation aimed at accelerating the Pentagon’s adoption of quantum sensing technology, part of a broader government effort to strengthen the country’s position in a rapidly developing field that could reshape defense, cybersecurity and advanced computing.

The National Quantum Readiness Act, introduced by Sens. Mike Rounds and Richard Blumenthal, would require the Defense Department to identify at least three priority quantum sensor projects within 60 days of enactment and set a goal of deploying those systems by Sept. 30, 2028.

The bill also calls for coordination among the Defense Department, Commerce Department, Energy Department and National Science Foundation to support partnerships with private quantum companies.

The legislation does not target cryptocurrencies or require blockchain networks to change their security systems. But it comes as governments worldwide prepare for the possibility that powerful quantum computers could eventually challenge some of today’s encryption methods..

The concern for digital assets comes from cryptography.

Bitcoin, Ethereum and many other blockchain networks rely on public-key cryptography to authorize transactions and protect user funds. Current computers cannot break these systems, and today’s quantum machines are not capable of doing so either.

The long-term concern is that sufficiently advanced quantum computers could make certain mathematical problems easier to solve, potentially threatening some forms of public-key encryption.

That is why governments and researchers are developing post-quantum cryptography (PQC) — encryption methods designed to withstand attacks from future quantum computers.

The U.S. government has already begun planning for that transition. A June 22 executive order directed federal agencies to move toward National Institute of Standards and Technology-approved post-quantum standards and help critical infrastructure operators prepare for future cryptographic risks.

For crypto projects, the challenge is preparation rather than an immediate security threat.

Bitcoin uses elliptic curve digital signatures, while Ethereum accounts also rely on elliptic curve cryptography. In theory, a sufficiently powerful quantum computer could compromise these systems. However, researchers have not built quantum machines capable of doing so.

There are also currently no government requirements forcing Bitcoin, Ethereum, exchanges or blockchain developers to adopt post-quantum standards.

Any transition would likely depend on decisions by blockchain communities, developers and infrastructure providers. Changing cryptographic systems could require major technical upgrades and coordination across networks.

The U.S. quantum strategy is focused on developing capabilities before the technology becomes a security risk.

Quantum sensing has more immediate defense applications, including navigation when GPS signals are unavailable and advanced detection systems. 

For the cryptocurrency industry, the quantum debate is becoming part of a larger discussion about long-term blockchain resilience.

The immediate priorities for Bitcoin and Ethereum remain network security, adoption and development. But as governments and industries move toward post-quantum security standards, blockchain projects may eventually need to evaluate whether their current cryptographic designs can withstand a future quantum era.
