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

Within the last years blockchain has become more in focus of the commodity trading sector because of its reputed potential. The characteristics of blockchain can be used to make it to an infrastructure technology. The trend toward the use of blockchain therefore furthers the optimization of the entire value chain and reduction of the friction costs within the trading process. To reduce friction costs and to make use of the characteristics of blockchain, the technology is being introduced as a radical innovation into the commodity trading value chain. The focus of this thesis is on the resulting effects on the value chain after implementation. The research is conducted in a qualitative way, with an inductive research approach. Data is collected in order to build the theory, and interviews are conducted using the Gioia methodology for data analysis. The findings indicate that the value chain as a source of competitive advantage is affected in an overall positive way for firms. Competitive advantage is supported by value-adding effects and cost reduction, which are both are enhanced through the use of blockchain. In addition, the results indicate that the competitive advantage of a company is also supported through power. The power that results from independence and control of data and information is enhanced by blockchain. It is therefore possible to conclude that the value chain of a company is positively affected by the radical innovation of blockchain. This leads to a greater competitive advantage for the company and positive performance in a competitive environment.

This book gathers the refereed proceedings of the 1st International Congress on Blockchain and Applications 2019, BLOCKCHAIN19, held in Ávila, Spain, in June 2019. Among the scientific community, blockchain and artificial intelligence are broadly considered to offer a promising combination that could transform the production and manufacturing industry, media, finance, insurance, e-government, etc. Nevertheless, there is no generally accepted approach, nor established best practices, for combining blockchain and artificial intelligence. The 21 papers presented here were carefully reviewed and selected from over 40 submissions. They highlight the latest advances in blockchain, artificial intelligence and their application domains, exploring innovative ideas, guidelines, theories, models, technologies, and tools, and identifying critical issues and challenges that researchers and practitioners will face in the near future.
