Dieses essential vermittelt einen Einblick in die Grundlagen von Smart Contracts. Smart Contracts sind kleine Computerprogramme, die vor allem im Zusammenhang mit der Blockchain-Technologie zum Einsatz kommen. Mit ihnen lassen sich Verträge digital abbilden, überprüfen und automatisiert vollziehen. Die damit verbundenen Potenziale sind bei weitem noch nicht ausgeschöpft, doch schon jetzt finden sich zahlreiche Anwendungsmöglichkeiten. Allerdings werfen Smart Contracts auch eine Reihe rechtlicher Fragen auf. Die Autoren erläutern die Bedeutung und die Struktur von Smart Contracts und geben einen Einblick in deren rechtliche Handhabung.

Neues von Bestsellerautor Tariq Rashid: Eine Einführung in die innovative Deep-Learning-Technik GANs "Die coolste Idee im Deep Learning in den letzten 20 Jahren" sagt Yann LeCun, einer der weltweit führenden Forscher auf dem Gebiet der neuronalen Netze, über GANs, die Generative Adversarial Networks. Bei dieser noch neuen KI-Technik treten zwei neuronale Netze gegeneinander an mit dem Ziel, Bilder, Ton und Videos zu erzeugen, die vom Original nicht zu unterscheiden sind. Dieses Buch richtet sich an alle, die selbst ausprobieren möchten, wie GANs funktionieren. Tariq Rashid zeigt Ihnen Schritt für Schritt, wie Sie mit dem populären Framework PyTorch Ihre eigenen GANs erstellen und trainieren. Sie starten mit einem sehr einfachen GAN, um einen Workflow einzurichten, und üben erste Techniken anhand der MNIST-Datenbank ein. Mit diesem Wissen programmieren Sie dann ein GAN, das realistische menschliche Gesichter erzeugen kann. Tariq Rashids besondere Fähigkeit, komplexe Ideen verständlich zu erklären, macht das Buch zu einer unterhaltsamen Lektüre.

Blockchain ermöglicht Peer-to-Peer-Transaktionen ohne jede Zwischenstelle wie eine Bank. Die Teilnehmer bleiben anonym und dennoch sind alle Transaktionen transparent und nachvollziehbar. Somit ist jeder Vorgang fälschungssicher. Dank Blockchain muss man sein Gegenüber nicht mehr kennen und ihm vertrauen – das Vertrauen wird durch das System als Ganzes hergestellt. Und digitale Währungen wie Bitcoins sind nur ein Anwendungsgebiet der Blockchain-Revolution. In der Blockchain kann jedes wichtige Dokument gespeichert werden: Urkunden von Universitäten, Geburts- und Heiratsurkunden und vieles mehr. Die Blockchain ist ein weltweites Register für alles. In diesem Buch zeigen die Autoren, wie sie eine fantastische neue Ära in den Bereichen Finanzen, Business, Gesundheitswesen, Erziehung und darüber hinaus möglich machen wird.

In this book, we take you on a fun, hands-on and pragmatic journey to learning decentralized application (DApp) development on the Ethereum blockchain using the Solidity programming language. You'll start building your first Ethereum smart contract within minutes. Every section is written in a bite-sized manner and straight to the point as I don't want to waste your time (and most certainly mine) on the content you don't need. In the end, you will have what it takes to develop a real-life decentralized eBay Clone app. In the first chapter, we see how Ethereum works and why do we care about it. In the second chapter, we will create our first working smart contract with Ethereum where we learn how to interact with Ethereum as developers. We will then move on to chapters three and four where we will learn about compiling, deployment and testing of Ethereum apps. All these will prepare us for development of our decentralized eBay clone smart contract and the React user front end in chapter five and six. The goal of this book is to teach you how to build decentralized apps with Ethereum. We won't be talking a lot about trading cryptocurrencies, how to invest in Ethereum or how to trade Ethereum (ether) coins. We will have a good overview of Ethereum and cryptocurrencies but we will not be going into super in-depth academic discussion of them as our focus in this book is to have the practical knowledge of how to work with and build products with Ethereum.

Akademische Arbeit aus dem Jahr 2018 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,6, Hochschule Ravensburg-Weingarten, Sprache: Deutsch, Abstract: In diesem Paper wird das Funktionsprinizp hinter Smart Contracts näher beschrieben und ein Beispiel dazu erläutert. Bei Smart Contracts handelt es sich um Computerprogramme, welche festgelegte Vertragsbedingungen validieren und ausführen. Darüber hinaus werden Smart Contracts im Hinblick auf Prozessunterstützung betrachtet und diesbezüglich ein konkreter Anwendungsfall vorgestellt. Die Vor- und Nachteile von Smart Contracts werden im Anschluss diskutiert. Das Paper endet mit einer Zusammenfassung. Blockchain, die Kerntechnologie von Bitcoin, hat in letzter Zeit umfangreiche Aufmerksamkeit erhalten. Blockchain dient als öffentliches Hauptbuch "public ledger", wodurch die in ihr gespeicherten Transaktionen fast unmöglich zu manipulieren sind. Die Technologie besitzt die Schlüsseleigenschaften Dezentralisierung, Persistenz, Pseudonymität und Transparenz. Durch diese Eigenschaften kann die Technologie in vielen verschiedenen Bereichen angewendet werden. In diesem Paper werden zunächst die Grundlagen hinter der Technologie aufgeführt, woraufhin der Fokus auf ein spezielles Anwendungsgebiet von Blockchains gelegt wird: Smart Contracts.
