Community Trust ScoreLikely Real
President Trump signed two executive orders on June 22. They’re already rattling the crypto world — and not in a small way.
The first order tells federal agencies to implement post-quantum cryptography for encryption keys by the end of 2030 and for digital signatures by the end of 2031. The second launches a program to build a quantum computer for scientific applications at a Department of Energy facility. Both orders together paint a pretty clear picture: the U.S. government thinks quantum threats are real, they’re coming faster than most people assumed, and Washington isn’t waiting around.
Nearly 7 million Bitcoin — worth roughly $449 billion at current valuations — sit exposed.
What the Orders Actually Say
The quantum development piece has a name: the Quantum Computer for Application Development and Discovery Science, or QC-ADDS. The order tied to it requires technical specifications to be defined within 90 days and cost and timeline evaluations within 180 days. Beyond that, a five-year plan calls for deploying quantum-enabled sensors and networks. It’s an aggressive roadmap, and the specifics matter — because every month the government moves faster on quantum capability is a month Bitcoin’s cryptographic foundation looks a little shakier.
The orders also push to grow the domestic quantum workforce and shield research from foreign espionage. Two new structures get created in the process: the National Quantum Workforce Development Institutes and a restructured Quantum Counterintelligence Protection Team. Neither of those is a small bureaucratic footnote — workforce gaps and foreign theft of quantum research have been real problems, probably for longer than officials wanted to admit publicly.
Short version: this isn’t a vague policy gesture. There are deadlines, agencies named, and programs funded.
Bitcoin’s Quantum Exposure Problem
About 65% of all Bitcoin are currently shielded from immediate risk because their public keys stay hidden until the coins are actually spent. Once spent — once that public key hits the blockchain — the protection disappears. A sufficiently powerful quantum computer could, in theory, reverse-engineer the private key from the exposed public key and drain the wallet. That’s the core vulnerability, and it’s not theoretical anymore. It’s a matter of timing.
Address reuse makes everything worse. When users repeatedly transact from the same wallet, the public key gets exposed over and over. In May 2026 alone, address reuse added 28,306 BTC to the pool of quantum-exposed coins. That’s not a rounding error.
And the concentration is striking. Around 84.5% of exposed Bitcoin sit in just 4,079 wallets. Many of those wallets have no public identification attached to them. Compliance firms trying to figure out which institutions or major holders face the most risk are basically working blind.
Then there’s the Satoshi problem.
Dormant Coins, Ancient Keys, No Easy Fix
Bitcoin mined in 2009 — coins widely associated with the network’s pseudonymous creator, Satoshi Nakamoto — are held in Pay-to-Public-Key outputs. That format permanently exposes the public key on the blockchain. Those coins haven’t moved in 16 years. Their keys are just sitting there, visible to anyone, waiting for a machine powerful enough to exploit them.
Migration to safer address formats has been slow. Too slow, probably, given the timeline Trump’s orders just set.
A draft proposal called BIP-361 tries to address this directly. It lays out a phased approach. Phase one: stop additional funds from being sent to quantum-vulnerable addresses. Phase two, proposed to kick in roughly five years after phase one: restrict conventional cryptographic methods — specifically the Elliptic Curve Digital Signature Algorithm (ECDSA) and Schnorr signatures — and require a new quantum-safe rescue process for spending those coins.
It’s a radical idea. And it forces a genuinely hard question onto the Bitcoin network: do you let dormant coins stay at risk and potentially get drained by a future quantum attacker? Or do you adopt measures that could permanently lock out those coins if their owners never migrate them in time?
Neither option is clean. Both carry real costs. The decentralized nature of Bitcoin means no single entity gets to make that call — it requires broad consensus among developers, miners, and the broader community. That kind of consensus can take years. Years the quantum timeline may not provide.
The BIP-361 proposal is still a draft. No activation date, no confirmed support from the broader developer community as of now. Details on implementation remain sparse.
But the pressure just got a lot more real. Trump’s June 22 orders set a hard government deadline for post-quantum cryptography by 2031. Bitcoin developers are now racing against a clock they didn’t set, on a timeline they didn’t choose, with 7 million coins and $449 billion hanging in the balance.
84.5% of the exposed Bitcoin. 4,079 wallets. Most of them anonymous.
Frequently Asked Questions
What did Trump’s executive orders on June 22 require for quantum computing?
The orders mandate federal agencies to adopt post-quantum cryptography for encryption keys by end of 2030 and digital signatures by end of 2031, and launch the QC-ADDS program to build a quantum computer at a Department of Energy facility.
How much Bitcoin is currently at risk from quantum computing attacks?
Roughly 7 million Bitcoin, valued at approximately $449 billion, are exposed due to publicly visible keys — with 84.5% of those coins concentrated in just 4,079 wallets.
