Quantum-Proof Blockchain Debate: Math vs. Machines

What happened: In a CoinDesk opinion piece, MIT professor and Optimum co-founder Muriel Médard argued that classical mathematics, specifically Random Linear Network Coding (RLNC), can deliver quantum-safe security for blockchains without the need for quantum computers. Médard claims encrypting just 10% of coded equations can protect 100% of data, reducing computational burden by 90% compared to full encryption. Optimum, backed by an $11 million seed round, is commercializing this approach.
Why it matters: The op-ed challenges the prevailing narrative that quantum-resistant blockchains require quantum hardware or entirely new cryptographic primitives. If RLNC’s claims hold up under independent scrutiny, it could offer a more efficient path to quantum safety. However, the argument comes from a party with a direct commercial stake, and no counter-analyses from cryptography experts have surfaced to date.
