Blockchain Explained from the Ground Up
Blockchain Made Easy provides a structured path through blockchain technology, filling the gap between overly promotional explanations and highly technical specifications. Written by university educators specializing in cybersecurity and information security engineering, the book introduces the subject from first principles and progresses toward practical blockchain development.
Designed for beginners and self-learners, it explains complex concepts clearly while gradually introducing the technical foundations behind modern blockchain systems.
What You’ll Learn

From Fundamentals to Smart Contracts
The learning journey begins with the cryptographic foundations that secure blockchain networks, including hashing, digital signatures, public-key cryptography, blocks, and Merkle trees.
The book then moves into detailed explorations of Bitcoin and Ethereum before introducing Solidity and practical smart contract development. Readers can explore token standards such as ERC-20, ERC-721, and ERC-1155 alongside NFTs and Web3 applications.
Practical Learning and Hands-On Exercises
Each chapter is designed to support both teaching and independent study. Learning objectives introduce the material, while summaries, key terms, review questions, discussion questions, practical exercises, and multiple-choice questions reinforce the concepts.
Hands-on labs provide practical experience, taking readers from an empty project folder through to a verified smart contract operating on a public test network.
DeFi, Web3 and Blockchain Security
Beyond the fundamentals, the guide examines decentralized finance, automated market makers, lending, liquidations, decentralized organizations, Layer 2 technologies, bridges, and cross-chain interoperability.
Security topics include 51% attacks, reentrancy, oracle manipulation, and MEV, giving readers a broader understanding of the risks and challenges associated with blockchain systems.
Honest About Blockchain’s Limitations
The book also examines major blockchain failures and security incidents, including The DAO hack, the Parity wallet freeze, the Ronin bridge theft, and the Terra collapse. It takes a practical look at where blockchain technology works, where it faces limitations, and whether using a blockchain is always the right solution.
The technical content is presented as verified through January 2026, covering developments including post-Merge proof of stake, EIP-4844 blob transactions, and contemporary blockchain development tooling.
