"Nat Eliason had six months to make as much money as possible before his first child was born. So, he turned to where so many others did in 2021: Crypto. Within a year, he'd made millions writing code holding hundreds of millions of dollars of other people's money. He'd been hacked. He'd sold a picture of a monkey for two hundred grand. He'd become an influencer, speaking at conferences, and writing a weekly newsletter to tens of thousands of fans. Best of all, Nat had amassed a small fortune. But how much of this money was even real? And how many times can someone double down before they eventually lose everything? Crypto Confidential is Nat's unfiltered, insider's account of the hyperactive, hyper-speculative, hyper-addictive, nearly unregulated, completely insane world being built on the blockchain. A behind-the-scenes exposâe of the bull runs and breakdowns, revealing exactly how the crypto-sausage gets made. A story of getting rich, going broke, scamming and getting scammed- and how we can all be more educated participants during the inevitable next bull run"--

A quiet revolution is taking place within the computer ecosystem; one that will change the way we do business on the internet.It's called blockchain, and it promises to disrupt the way people interact with one another online, whether its messaging, banking, keeping up with medical records, land records, booking a vacation, socializing, or voting. Programs are also being developed to use blockchain to serve as one's identity "papers."Blockchain technology is based on the idea that all online transactions should be between two people without the need for public or private third-party oversight. Blockchain technology developers believe thoughts and ideas should be shared, not quashed. It's a world where web platforms are governed by their members, not a board of directors; privacy comes first, and one's personal information is kept private, not for third parties to take and sell as they, please.Blockchain technology offers everyone opportunities to take part. Anyone can participate in the fast-growing world using non-fungible tokens (NFTs), where works of art, music, literature, and poetry can be tokenized and sold or traded on a blockchain.These components comprise the next generation of the world wide web, which is referred to as Web 3.0. Billions of dollars are being spent to create infrastructure to create a viable framework to mainstream blockchain.This book offers a peek into this new world with examples of how this technology is being used today as well as the hurdles, including legal challenges, it must overcome to be viable.So, if you're ready, let's meet blockchain.

NFTs cause excitement and skepticism. How much value can a token hold? What drives this value?To properly appreciate NFTs we must first understand what they actually are, how they work and in what contexts they are used.The Everything Token is an essential primer on NFTs (non-fungible tokens), explaining their use, purpose, and how businesses can create and exploit them to develop new product lines, building customer loyalty and increased revenues at the same time.Together the authors have spent much of the past few years embedded in NFT communities and helping launch NFT products. As self-described beta testers of this brand-new technology, they've seen its power first-hand and aim to educate others on the importance, uses and purpose of NFT and surrounding, ever-evolving technologies.Demystifying the complexities, two experts in NFTs show why we should take NFTs much more seriously than their reputation as fun digital art collectibles suggest. They have a wider variety of uses than one may realise.Gripping and accessible, this book provides a guide and an insight into what can often be a hard-to-grasp area of technology.

Die Besteuerung von Kryptowährungen stellt sowohl in der wissenschaftlichen als auch der steuerlichen Praxis ein immer größer werdender Themenbereich dar. Die Beantwortung der sich stetig aufwerfenden Fragen setzt neben einem Verständnis für die zugrundeliegende Technologie und der zivilrechtlichen Einordnung vor allem eine kritische Auseinandersetzung mit den Grundsätzen des deutschen Steuerrechts voraus. Die vorliegende Arbeit gibt zunächst einen Einblick in die technischen Grundlagen von Kryptowährungen sowie den einzelnen technischen Implikationen. Nach einer kurzen zivilrechtlichen Würdigung werden Einblicke in die einzelnen Aspekte der Besteuerung, insbesondere auf die differenzierte Betrachtung innerhalb der einzelnen Krypto-Token Typen und der verschiedenen Anwendungen gewährt. Ein besonderer Schwerpunkt stellt dabei die Besteuerung von Krytpo-Token aus seiner Hard-Fork dar, deren Besteuerung nach dem deutschen Steuerrecht einen über die Ansicht des BMF hinausgehende Handlungspflicht des Gesetzgebers erfordern dürfte. Insgesamt lässt der stetige Wandel und das wachsende Interesse sowohl der Politik als auch der Anleger an Kryptowährungen im Hinblick auf eine der Technologie gerecht werdenden Besteuerung für die Zukunft viele spannende rechtliche Wendungen und Debatten erwarten.

"The Internet of today is a far cry from its early promise of a decentralized, democratic network of creativity and innovation. In the past decade, the Internet has fallen under the control of a tiny group of massive companies like Apple, Google, and Facebook. In Read Write Own, tech visionary Chris Dixon argues that the dream of an open network for fostering creativity and entrepreneurship doesn't have to die, and that in fact it can, and must, be saved with blockchain networks, which he vitally separates from the currency-based speculation that it is unfortunately lumped together with - a distinction he calls "The Computer vs The Casino". With lucid and compelling prose - and drawing from his first-hand observations, mental models, and experiences over a 25-year career in the Internet industry - Dixon shows how the Internet has undergone three distinct eras, bringing us to the critical moment we're in today. The first act was the "read era," lasting from 1990 to 2005, in which early Internet networks democratized information. In the "read-write era," 2006-2020, corporate networks democratized publishing. And we are now entering the "read-write-own era," sometimes called web3, in which blockchain networks have begun to democratize ownership, granting power and economic benefits to the participants in the network--not just to massive corporations"--

'An essential resource. Howson strikes not just at cryptocurrency, but the frauds who promote blockchain technology as a solution to any social problem' David Gerard, author of Attack of the 50 Foot Blockchain'A merciless takedown of attempts to apply blockchain to the world's biggest problems ... If you are thinking of using blockchain for good, read this first' Professor Villi Lehdonvirta, University of OxfordThe subject of immense hope, hype and confusion, crypto has amassed countless headlines in recent years. With cryptocurrencies, NFTs and metaverse markets crashing, the underlying blockchain technology is still promised to solve global development challenges, and revolutionise every industry. But is the technology really a silver bullet?Peter Howson cuts through the jargon and bluster to tell an alarming story of how right-wing libertarian crypto entrepreneurs - often aided by charities, politicians and philanthropists - seek out and exploit conditions of poverty, oppression, corruption and conflict. Their goal? A new front of 'crypto-colonial' extractivism. Let Them Eat Crypto reveals the alarming truth: far from 'banking the unbanked', saving the gorillas, or freeing people from oppressive governments, blockchain offers only false solutions, surveillance and hi-tech snake oil.Peter Howson is a technology writer, researcher and Assistant Professor in International Development at Northumbria University. His work has appeared in Reuters, The Independent, The Conversation, Novara, Jacobin and Coindesk. He investigates the green-washing, aid-washing and crypto-shenanigans that go on in Silicon Valley, as well as the lesser-known tech-hubs of the Global South.

Felix Müller-Eising untersucht die Nutzung der Blockchain-Technologie für das Grundbuch, das Handelsregister und das Aktienregister. Zuerst wird eine Einführung in die allgemeine Funktionsweise einer Blockchain gegeben, wobei Token, kryptografische Schlüssel, Smart Contracts und Konsensmechanismen wie Proof-of-Work und Proof-of-Stake erläutert werden. Danach werden dezentrale und zentrale Einsatzmöglichkeiten einer Blockchain für die Register untersucht. Er kommt zu dem Ergebnis, dass sowohl das Grundbuch als auch das Handelsregister durch eine Blockchain keinen deutlichen Mehrwert erhalten würden. Dagegen habe die Tokenisierung von Aktien in einem blockchainbasierten Aktienregister einige Vorteile, die den Einsatz einer Blockchain rechtfertigen würden.
