About book : The decentralized applications in industry are gaining tremendous importance today due to the unique features possessed by them. Decentralized blockchain applications provide a secure and transparent platform for peer-to-peer transactions without the need for intermediaries. These applications offer increased privacy and control to users, as data is stored on a distributed ledger which is immutable and tamper-proof. Decentralized blockchain applications have the potential to revolutionize industries by creating new business models and disrupting traditional ones. The decentralized nature of blockchain applications also makes them resilient to hacking attempts and downtime, ensuring continuous availability. To leverage the power of blockchain tools the current book provides an in-depth and elaborative content for DApp aspirants. The book intends to provide a solid foundation for blockchain developers on usage of various blockchain tools to overcome the intricacies involved in blockchain application development. Chapter 1 focuses on advanced concepts in Solidity. Chapter 2 explores the Geth tool which facilitates creating a private blockchain network. Chapter 3 provides an overview of truffle which provides a streamlined development experience for Ethereum developers, allowing them to focus on building and deploying high-quality, secure, and scalable DApps. Chapter 4 provides in-depth understanding of infura which is Infura is a cloud-based infrastructure provider for decentralized applications (DApps) that allows developers to access the Ethereum and IPFS networks without having to run their own node. Chapter 5 is completely devoted to web3.js. which is a JavaScript library that provides a way for developers to interact with the Ethereum blockchain and build decentralized applications (DApps). Finally Chapter 6 unleashes IPFS is a JavaScript library that provides a way for developers to interact with the Ethereum blockchain and build decentralized applications (DApp
