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

In den letzten Jahren ist die Abhängigkeit von der Informationstechnik (IT) derart gestiegen, dass heutzutage kein Unternehmen mehr ohne sie auskommt. Vielmehr ist die effektive und effiziente Nutzung der IT zum entscheidenden Wettbewerbsfaktor im globalen Markt geworden. Dabei geht es um Arbeitsprozesse die in vielen Fällen bereits elektronisch gesteuert und überwacht werden. Große Mengen von Informationen sind digital gespeichert, werden zielführend verarbeitet und in Netzen übermittelt, so dass ein gemeinsamer, standort- und geräteunabhängiger Zugriff ermöglicht wird. Dieses erlaubt intensive Formen der Kooperation über geographische Grenzen hinweg, verdeutlicht aber gleichzeitig auch die Abhängigkeit von derartigen Datennetzen. Das gleiche gilt für die drahtlose Kommunikation der verschiedenen kleinen und kleinsten IT-Einheiten untereinander, die mittlerweile in alle Bereiche des beruflichen und privaten Alltags integriert werden. In einer derart digitalisierten Gesellschaft sind die verschiedenen Institutionen in Wirtschaft und Verwaltung stark von dem einwandfreien Funktionieren aber auch von einem gewissen Verständnis für die eingesetzte IT abhängig. Genau hier setzen die dreizehn Beiträge dieses Buches an mit dem Ziel, einen kompakten Überblick über aktuelle Themen und Trends der Informationstechnik zu geben. Sie wurden von Masterstudierenden der Wirtschaftsinformatik der Fachhochschule Dortmund im Rahmen einer Semesterbegleitleistung im Masterkurs "Informationswirtschaft" verfasst. Jeder Beitrag behandelt ein spezielles Thema, in das zuerst allgemein eingeführt wird. Anschließend wird es mit seinen verschiedenen Facetten, d.h. mit Anwendungsbeispielen, Chancen und Risiken oder auch Vor- und Nachteilen möglichst umfassend dargestellt. Den Abschluss der Beiträge bilden fast immer ein Fazit und ein Ausblick, die für die Leser richtungsweisend sein sollen.

Bachelor Thesis from the year 2018 in the subject Economics - Finance, grade: 1,7, University of Applied Sciences Essen, language: English, abstract: The progress of change in society through digitization, globalization and the rapid development of technology prompts new and innovative opportunities for companies across the world. Over the past few years, nearly everything is based on smart devices that are able to communicate among themselves. As a result, new technologies have arisen, been published and are able to be used by people around the world. One of the recently released and most popular topics is blockchain. This term earned its attention through its innovative and unpresented form of technology and has motivated several parties to learn more about this issue, examine it more closely and develop it further. Particularly the range of potential applicability makes it interesting for companies to analyse possibilities for implementation with respect to their own business. In addition, blockchain is related to another term that has arisen along with this technology, namely cryptocurrency. Especially Bitcoin is the forefather in the world of digital currencies. Over the past few years, Bitcoin has skyrocketed in popularity and value since its founding in 2009. Consequently, this digital currency has gained the attention of many people who are trying to predict the commercial development and future per- formance in the world’s economy. There are many pros and cons and some powerful businessmen have published their own opinions based upon the respective commercial interests. ...
