Quantum-Proof Blockchains Rely on Classical Mathematics
Optimum co‑founder and MIT professor Muriel Médard argues that blockchains can achieve quantum safety without quantum computers, using established mathematical techniques.

Optimum co‑founder and MIT professor Muriel Médard asserts that blockchains do not require quantum computers to become quantum‑safe. She emphasizes that existing mathematical methods already provide the necessary tools for quantum resistance.
Key Argument
The central claim is that classic math, rather than advanced quantum hardware, holds the solution for securing blockchain technology against future quantum threats.
Implications for the Industry
- Focus on mathematical research could accelerate quantum‑proof developments.
- Blockchain projects may prioritize algorithmic upgrades over hardware changes.
