MIT's Muriel Médard Argues Blockchains Can Be Quantum-Safe Without Quantum Hardware

Her proposal splits data into coded equations and encrypts roughly one in ten of them, which she says protects the whole payload while cutting the computational burden by about 90%.

Muriel Médard, a professor at the Massachusetts Institute of Technology and co-founder of the networking company Optimum, argues that blockchains do not need quantum computers to defend against them. Her case rests on classical mathematics…
