The federal government is moving on two tracks that are headed toward a collision.
On one track, it is investing billions of dollars to accelerate quantum computing and requiring federal agencies to migrate critical systems to post-quantum cryptography by 2030 and 2031.
On the other, policymakers are rapidly integrating quantum-vulnerable blockchain infrastructure into the financial system through stablecoins, tokenized securities, federally chartered crypto firms, and exchange-traded products.
The crypto industry increasingly recognizes that it has a problem. Coinbase, BitGo, the Bitcoin Security Consortium, and others have begun preparing for post-quantum migration, and there is a growing technical debate over how blockchains should upgrade, protect exposed wallets, and address dormant assets that cannot migrate themselves.
Financial regulators, however, have been almost entirely silent about what this means for custody, stablecoins, tokenized markets, collateral, and financial stability.
The latest Senate draft of the CLARITY Act acknowledges that quantum computing threatens digital assets. But its response is limited to guidance, technical assistance, and “voluntary, market-driven measures.” It imposes no migration deadline, planning obligation, or quantum-readiness standard on the institutions it would federally license.
My new blog post summarizes the problem, and my accompanying working paper proposes a federal quantum-resilience perimeter designed to protect regulated finance while preserving self-custody and leaving technical decisions to protocol communities.

This is a working draft, and I welcome feedback from financial regulators, lawyers, cryptographers, blockchain developers, market participants, and others thinking about the intersection of quantum computing, digital assets, and financial stability.
