Chapter 19: The Quantum Leap

Quantum computing is the next natural stage in computing, and will revolutionize how big questions in computing are addressed, including in cryptography.  Many anticipate advanced quantum computers to defeat what today is considered strong cryptography, allowing users to undo, alter or dominate existing blockchains.  In addition to serving as a basic introduction to concepts in quantum computing, his chapter addresses not just the impacts for blockchains, but how the advances in cryptography brought on by blockchain will have applications in countering the advantages held by strong quantum computers, and in protecting friendly quantum computers as they interact with the wider network.
