Quantum-Safe Blockchains May Depend on Mathematics, Not Quantum Hardware

Blockchain networks may not need access to quantum computers to prepare for quantum-related security risks, according to Muriel Médard, co-founder of Optimum and a professor at MIT. In an analysis published by CoinDesk, Médard argues that established mathematical methods already provide the foundation for building quantum-safe systems. The focus, therefore, is on applying and adapting proven mathematical tools rather than waiting for quantum machines to become available. Her view challenges the assumption that progress toward quantum-resistant blockchain technology depends on developing quantum hardware first. The discussion is relevant to crypto-market participants assessing how blockchain infrastructure could evolve as concerns around quantum computing grow.
