Introduction to Blockchain

"Introduction to Blockchain" is crafted to align with the Skill Enhancement Course at the University of Delhi, under the National Education Policy 2020 guidelines. This book serves as a primer on the basic concepts of blockchain technology, which is poised to revolutionize industries by enabling transparency, enhancing security, and facilitating transactions without the need for intermediaries. Structured in two units, the book first lays the groundwork by explaining the blockchain's foundational aspects—its architecture, underlying mechanisms, and its role in fostering decentralization and trust through cryptographic practices. The initial chapters look into the workings of Ethereum and Hyperledger Fabric, illustrating their relevance in developing decentralized applications (DApps). The second unit shifts focus on practical implementation, including setting up blockchain environments, crafting smart contracts using Solidity, and building DApps. It not only details the theoretical aspects but also provides hands-on exercises that underscore the practical challenges and the profound implications of blockchain technology in real-world scenarios. Comprehensive yet concise, this textbook is an indispensable resource for anyone looking to understand the pivotal concepts of blockchain technology and its applications across various sectors.
