Description Blockchain is a revolutionary technology that shook the core of the finance world. However, Blockchain is not just about cryptocurrency. This book focuses on blockchain, its features, and the core technologies used to build the Blockchain network. In the first section, you will learn about blockchain in-depth. You will learn how these currencies work and how you can build your applications using them. This edition focuses on Ethereum as a platform for building decentralized applications (DApps) and smart contract development using Solidity. You will learn about decentralized databases like OrbitDB, BigchainDB, TiesDB, and Bluzelle, and understand their role in building next-generation applications. You will also learn about various databases and how to use them in detail. Lastly, you will understand how the existing DApps work, their architecture, and how they are incorporated into the application for the end-user. Key Features Explore the engineering mechanism of blockchain, cryptocurrency, and Ethereum. Know-how of peer-to-peer networks, IPFS, and decentralized databases. Explore the workings of DApps and build your own blockchain app. This edition includes consensus algorithms like PoW and PoS, scaling solutions, and interoperability. What you will learn Learn to build your own P2P network. Cutting-edge coverage on how cryptocurrency works. Learn smart techniques to develop your own DApps on the Ethereum platform. Learn to use decentralized databases, including OrbitDB. Implement PoW, PoS, and PBFT to secure blockchain networks and analyze sharding and layer-2 techniques for scalability. Who this book is for This book is for anyone who wants to become a blockchain developer or wants to build an application using blockchain. Full stack developers, software engineers, web programmers, and beginners who are interested in blockchain can find this book a true handy guide to begin their career in blockchain.
