Quantum-Proof Blockchain

This is a book for the people who build and for the people who decide what gets built. Blockchain or smart-contract developers who want to future-proof their skills are exactly the intended audience. Architects, chief technology officers, or security officers evaluating infrastructure that has to remain trustworthy for decades will find the book provides the technical grounding to make those decisions well. Founders weighing platform choices, auditors extending their practice to post-quantum contracts, and researchers and educators looking for a practical complement to the theory will all find a path through it.Readers will get the most from these pages if they arrive with working knowledge of Solidity and a basic understanding of how a blockchain operates. A background in cryptography, mathematics, or physics is not required: the relevant ideas are introduced from the ground up, at the depth a builder needs and no deeper.The book is a practical one, and practice means code. More than thirty hands-on labs accompany the chapters, and a companion repository hosts every example, test, and deployment script in full, so readers can run, modify, and build on them rather than retyping them. Readers are encouraged to keep an editor open as they read; the concepts settle far more firmly once they have deployed them themselves, and the final chapter assumes they are ready to do exactly that
