This document summarizes a research article on developing post-quantum blockchain cryptography that is resistant to quantum computing attacks. It first discusses how quantum computers threaten current blockchain cryptography based on public-key algorithms and hash functions. It then reviews state-of-the-art post-quantum cryptosystems that could replace these, including lattice-based and multivariate-based encryption and signature schemes. The document analyzes the performance of promising post-quantum algorithms on hardware suitable for blockchain nodes. It also summarizes several existing blockchain proposals that incorporate post-quantum cryptography. The overall goal is to provide guidance to researchers on developing secure blockchain systems resilient to future quantum computers.
