Traditional database technologies present several challenges in recording financial transactions. As an example, this can be seen in the case of property sales, where the buyer's ownership is obtained after payment has been completed. Both buyers and sellers can record monetary transactions, but there is no reliable source. However, all parties can deny each other. Blockchain is a database that contains a history of whatever information it is designed to store. Blockchain consists of a series of information "blocks" built on top of one another in an immutable chain. This book guides developing Smart Contracts with Solidity, on Polygon. Ethereum is a lovely blockchain to work with, but the heavy traffic and many people building on it have made the network a bit congested. The 2nd layer solution to solving this problem by extending the scalability of Ethereum is with Polygon. Polygon is an Ethereum companion network with Ethereum security and lower gas fees.

Deep and machine learning is the state-of-the-art at providing models, methods, tools and techniques for developing autonomous and intelligent systems which can revolutionise industrial and commercial applications in various fields such as online commerce, intelligent transportation, healthcare and medicine, etc. The ground-breaking technology of blockchain also enables decentralisation, immutability, and transparency of data and applications. This event aims to enable synergy between these areas and provide a leading forum for researchers, developers, practitioners, and professionals from public sectors and industries to meet and share the latest solutions and ideas in solving cutting-edge problems in the modern information society and the economy. The conference focuses on specific challenges in deep (and machine) learning, big data and blockchain. Some of the key topics of interest include (but are not limited to): Deep/Machine learning based models Statistical models and learning Data analysis, insights and hidden pattern Data visualisation Security threat detection Data classification and clustering Blockchain security and trust Blockchain data management

Learn how to use Solidity and the Ethereum project – second only to Bitcoin in market capitalization. Blockchain protocols are taking the world by storm, and the Ethereum project, with its Turing-complete scripting language Solidity, has rapidly become a front-runner. This book presents the blockchain phenomenon in context; then situates Ethereum in a world pioneered by Bitcoin. See why professionals and non-professionals alike are honing their skills in smart contract patterns and distributed application development. You'll review the fundamentals of programming and networking, alongside its introduction to the new discipline of crypto-economics. You'll then deploy smart contracts of your own, and learn how they can serve as a back-end for JavaScript and HTML applications on the Web. Many Solidity tutorials out there today have the same flaw: they are written for “advanced” JavaScript developers who want to transfer their skills to a blockchain environment. Introducing Ethereum and Solidity is accessible to technology professionals and enthusiasts of all levels. You’ll find exciting sample code that can move forward real world assets in both the academic and the corporate arenas. Find out now why this book is a powerful gateway for creative technologists of all types, from concept to deployment. What You’ll Learn See how Ethereum (and other cryptocurrencies) work Compare distributed apps (dapps) to web apps Write Ethereum smart contracts in Solidity Connect Ethereum smart contracts to your HTML/CSS/JavaScript web applications Deploy your own dapp, coin, and blockchain Work with basic and intermediate smart contracts Who This Book Is For Anyone who is curious about Ethereum or has some familiarity with computer science Product managers, CTOs, and experienced JavaScript programmers Experts will find the advanced sample projects in this book rewarding because of the power of Solidity

An in-depth and authoritative treatment of one of the most pressing topics of our time In Blockchain and Web3: Building the Cryptocurrency, Privacy, and Security Foundations of the Metaverse, two tech and finance experts deliver a comprehensive and accessible guide to the present and future of blockchain technology and how it will form the foundation of a new, better internet. To support a concept as bold as the Metaverse, we need several orders of magnitude more powerful computing capability, accessible at much lower latencies, across a multitude of devices and screens. You’ll discover how blockchain can accelerate data flow, exchange, and transactions to create and transfer value around the world and, at the same time, how it can be used to protect user data privacy and security with decentralized web infrastructures. The book also includes: Discussions of how sovereign governments are entering the blockchain fray and how their entry, especially with CBDC digital currency, shapes the conversations around Web3 Explorations of whether we will ever realize the holy grail of blockchain tech: interoperability to compete with Big Tech platforms Discussion of new security and privacy issues rising from the intersection of Blockchain, Web3 and Metaverse.A fascinating and eye-opening treatment of the past, present, and future of blockchain and the role it will play on the internet and metaverse, Blockchain and Web3 is a truly original and engaging discussion of a timely and critical topic.

This book proposes new technologies and discusses future solutions for ICT design infrastructures, as reflected in high-quality papers presented at the 7th International Conference on ICT for Sustainable Development (ICT4SD 2022), held in Goa, India, on 29–30 July 2022.
