Quantum-Proofing the Blockchain
Author: Vlad Gheorghui, Sergey Gorbunov, Michele Mosca, Bill Munson
Release Date: November 23, 2017
This project examines the quantum threat to blockchain technology, with its heavy reliance on public-key cryptography. It underscores the urgent need for quantum-resistant algorithms, international standards for cryptosystems, and a large-scale retooling of information and communications technology infrastructure worldwide. The authors distinguish types of quantum adversaries and analyze our options—from patching methods to building quantum-resistant blockchains from scratch.
