UN Discusses Quantum Risks for Banks and Blockchain
The UN session puts the focus on post-quantum migration, with NSA and NIST guidance as the starting point. The UN pension fund’s blockchain system is also under review.
Key Takeaways
- The UN discussed how banks and institutions are preparing for post-quantum cryptography, as the NSA and NIST speed up the move to quantum-resistant standards.
- The UN pension fund is exploring a quantum-resistant blockchain and re-encrypting historical records for its proof-of-life system with 80,000 beneficiaries.
- The discussion also touches crypto, because wallets, transactions, and blockchain infrastructure run on the same cryptographic principles and take time to adapt.
Quantum computers may not yet be powerful enough to break modern encryption on a large scale, but governments and financial institutions are no longer waiting around. During a regulatory session at UN headquarters in New York, the main question was how systems are preparing for post-quantum cryptography, now that the US NSA has already set a clear migration path.
Pressure on Financial Systems
The NSA wants new commercial national security systems to support quantum-resistant algorithms starting in 2027. Incompatible systems must be phased out by 2030 at the latest. That fits into a broader shift, because NIST has already finalized post-quantum standards and is pushing for migration instead of waiting until powerful quantum computers are actually available.
The core concern is simple: attackers can already steal encrypted data today and try to decrypt it later once quantum computers are far enough along. That means the debate is not just about future attacks, but also about information that is already being stored now.
The UN Pension Fund Looks Ahead
Brian McGleenon spoke at the event with IRS Chief Risk and Control Officer Dottie Romo, UN Joint Staff Pension Fund Deputy Chief Executive Dino Cataldo Dell’Accio, and Mastercard executive Julius Moye. Dell’Accio said quantum is already a concrete issue for the blockchain-based proof-of-life system of the pension fund, which serves about 80,000 beneficiaries in 190 countries.
According to him, it is not just about building new systems, but also about keeping existing blockchain data safe if current cryptography becomes vulnerable. That is why the fund is exploring a quantum-resistant blockchain and ways to re-encrypt and publicly record historical records.
Dell’Accio also warned that there may not be a clean Q-Day when institutions can simply switch over and be done. Quantum-safe keys can be much larger, which could also mean firewalls, network equipment, and software may need to be adjusted.
Why This Also Matters for Crypto
For crypto, this matters because the same cryptographic principles sit underneath wallets, transactions, and blockchain infrastructure. If large institutions are already planning migration now, that says something about how much time it takes to adapt systems and how complex that transition is.
Ripple's migration plan for the XRP Ledger also shows that major blockchain projects are already taking post-quantum security into account. Romo closed with a broader warning about timing. According to her, risk is still being viewed in a traditional way right now, but that will not be sustainable over time. That makes quantum not just a technical topic, but also a question of oversight, planning, and operational resilience.
