Guest Post: Quantum-Resistant Wallets Could Support Institutional Blockchain Adoption

Guest Post by Seb Audy | COO at AmericanFortress, COO at Moon Pursuit Capital

Institutional finance has a problem with how it approaches blockchain security. We are spending billions building systems intended to hold and move assets for decades, while much of the cryptography protecting those assets was designed without quantum computing in mind. For an industry that measures risk in basis points and spends enormous sums protecting against unlikely events, that inconsistency is odd.

I think quantum-resistant wallets could meaningfully affect institutional blockchain adoption because they address a question banks and asset managers will eventually have to answer: how comfortable are you holding billions in assets on infrastructure whose security assumptions may have an expiration date?

Nobody knows when a cryptographically relevant quantum computer will arrive. But a bank doesn’t evaluate infrastructure solely against the threats it faces this morning. It considers how that infrastructure will perform throughout its useful life, what replacing it might cost, and whether it can withstand foreseeable risks.

Consider a pension fund allocating capital to tokenized bonds or a custodian safeguarding digital assets for institutional clients. Some positions could remain in custody for decades. The institution responsible needs to know whether the mechanisms controlling ownership and authorization can be upgraded as cryptographic standards change.
