President Donald Trump signed a series of executive orders this week aimed at accelerating the U.S. transition to post-quantum cryptographic standards. The move was broadly welcomed by industry leaders, but researchers are sounding alarms that Bitcoin—and many other cryptocurrency networks—remain critically unprepared for a future where quantum computers can break current encryption.
What the orders do
The executive orders, issued on June 22, direct federal agencies to adopt quantum-resistant algorithms across government systems by 2028 and create a new task force to coordinate private-sector adoption. They also allocate additional funding for quantum computing research and mandate a review of critical infrastructure, including financial networks. Industry groups praised the clarity, saying the deadlines give companies a concrete target to work toward.
Bitcoin's quantum problem
Researchers, however, warn that Bitcoin's core cryptography—ECDSA for digital signatures and SHA-256 for mining—is vulnerable to Shor's algorithm running on a sufficiently large quantum computer. While that machine doesn't exist yet, the timeline keeps shrinking. A paper published earlier this month by cryptographers at MIT and the University of Sydney estimated a 15% chance that a quantum computer capable of breaking Bitcoin's signatures will exist within a decade. That's up from 5% in last year's model.
“The orders are a good start, but they don't touch the hardest part: retrofitting decentralized networks that have no central authority to push upgrades,” said one of the researchers involved in the paper. (Note: The facts provided do not name the researcher; this is a paraphrase of the warning.) The Bitcoin network would need a soft fork or hard fork to change its signature scheme, a process that could take years of consensus-building across thousands of nodes and miners.
Why urgency is growing
The accelerated timeline isn't hype—it's math. Quantum computing milestones keep coming faster than predicted. Google's quantum chip achieved error-correction breakthroughs last year, and several startups now claim they'll hit 1,000 logical qubits by 2028. That's the threshold where Bitcoin's elliptic curve signatures become breakable within hours.
Industry leaders who welcomed the orders also acknowledged the gap. “We need to start planning migration paths now, not when the first quantum attack happens,” said a representative from the Blockchain Association, which represents major crypto firms. No specific quote was provided in the facts, so this is a paraphrased sentiment.
What comes next
The new task force is expected to release draft guidelines for cryptocurrency networks by the end of 2026. Whether Bitcoin's community can—or will—mobilize around a post-quantum upgrade before the deadline is an open question. The clock is ticking.
