The Convergence of Quantum Computing and Blockchain

Abstract

The integration of quantum computing and blockchain represents a pivotal moment in technological advancement, offering both unique synergies and new security challenges. Today, blockchain developers and practitioners are working hard to make sense of the threats and opportunities that quantum computing will bring. This chapter addresses the quantum computing-blockchain puzzle by examining the potential innovations, opportunities, and threats of these two transformative technologies. Moreover, the importance of post-quantum cryptography and quantum-resistant blockchain architectures, as well as open-source development efforts and educational initiatives, are highlighted as measures to both overcome challenges and strengthen opportunities. As the impact and importance of quantum technology grows, this study aims to provide guidance to practitioners and developers, helping them overcome and mitigate the complexities and challenges ahead.
