The new book from one of TIME's 2021 most influential people Author was in Forbes 30 Under 30 Hall of Fame "A crucial contribution to development of a new technology that will impact all of our lives.” –Laura Shin, host of the Unchained podcast and author of The Cryptopians: Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze “Vitalik Buterin is one of the most influential creators of our generation....Like most of his work, it is sure to become a must-read.”–Camila Russo, author of The Infinite Machine, founder of The Defiant The ideas behind Ethereum in the words of its founder, describing a radical vision for more than a digital currency—reinventing organizations, economics, and democracy itself in the age of the internet. When he was only nineteen years old, in late 2013, Vitalik Buterin published a visionary paper outlining the ideas behind what would become Ethereum. He proposed to take what Bitcoin did for currency—replace government and corporate power with power shared among users—and apply it to everyday apps, organizations, and society as a whole. Now, less than a decade later, Ethereum is the second-most-valuable cryptocurrency and serves as the foundation for the weird new world of NFT artworks, virtual real estate in the metaverse, and decentralized autonomous organizations. The essays in Proof of Stake have guided Ethereum’s community of radicals and builders. Here for the first time they are collected from across the internet for new readers. They reveal Buterin as a lively, creative thinker, relentlessly curious and adventuresome in exploring the consequences of his invention. His writing stands in contrast to the hype that so often accompanies crypto in the public imagination. He presents it instead as a fascinating set of social, economic, and political possibilities, opening a window into a conversation that far more of us could be having. Media scholar Nathan Schneider provides introductions and notes.

A book of poetry by Charles Valle

Handbook of Research on Blockchain Technology presents the latest information on the adaptation and implementation of Blockchain technologies in real world business, scientific, healthcare and biomedical applications. The book's editors present the rapid advancements in existing business models by applying Blockchain techniques. Novel architectural solutions in the deployment of Blockchain comprise the core aspects of this book. Several use cases with IoT, biomedical engineering, and smart cities are also incorporated. As Blockchain is a relatively new technology that exploits decentralized networks and is used in many sectors for reliable, cost-effective and rapid business transactions, this book is a welcomed addition on existing knowledge. Financial services, retail, insurance, logistics, supply chain, public sectors and biomedical industries are now investing in Blockchain research and technologies for their business growth. Blockchain prevents double spending in financial transactions without the need of a trusted authority or central server. It is a decentralized ledger platform that facilitates verifiable transactions between parties in a secure and smart way. - Presents the evolution of blockchain, from fundamental theories, to present forms - Explains the concepts of blockchain related to cloud/edge computing, smart healthcare, smart cities and Internet of Things (IoT) - Provides complete coverage of the various tools, platforms and techniques used in blockchain - Explores smart contract tools and consensus algorithms - Covers a variety of applications with real world case studies in areas such as biomedical engineering, supply chain management, and tracking of goods and delivery

Deepen your understanding of blockchain technology and develop your own blockchain applications. This book provides a thorough review of distribution-based systems on blockchain technology, starting from the fundamental concepts that underlie it, all the way through the implementation of a blockchain network for business purposes. Author Joseph Thachil George begins by introducing you to blockchain and some basic concepts of technology, including distributed systems, systems of systems, cyber-physical systems, the Byzantine Consensus, the CAP theorem, and cryptographic techniques. Next, he analyzes the structure of blocks and smart contracts and the mother of all blockchain platforms, Bitcoin. That sets the stage for an examination of transaction structure, validation, and flow, from creation to registration in the ledger and structure of the blocks, the Nakamoto consensus, and finally forks. From there, you’ll experience a deep dive into Ethereum; including the concepts of Gas and Message, smart contracts and the Ethereum virtual machine. From there, you’ll learn about the Ethereum consensus protocol, Ethereum Casper, and the Ethereum Proof-of-Stake algorithm. You’ll then see how blockchain can be connected to a distributed system, followed by a demonstration of how you can model a distributed system using Blockly4SoS and Kilobots. The concluding chapters offer a practical example that combines distributed systems with blockchain technology. After reading this book, you will understand how to implement blockchain technology in a distributed system and be able to leverage this knowledge in your own projects. What You Will Learn Learn the concept of blockchains by way of a practical example Grasp the connection between distributed systems and blockchain technology Learn the design of blockchain with hyperledger fabric Learn the design of cyber-physical systems in a distributed environment Who Is This Book For Developers who are enthusiastic about the design and implementation of distributed systems.

This book constitutes the refereed proceedings of three workshops heldat the 20th International Conference on Financial Cryptography and DataSecurity, FC 2016, in Christ Church, Barbados, in February 2016. The 22 full papers presented were carefully reviewed and selected from 49 submissions. They feature the outcome of the Second Workshop on Bitcoin and Blockchain Research, BITCOIN 2016, the First Workshop on Secure Voting Systems, VOTING 2016, and the 4th Workshop on Encrypted Computing and Applied Homomorphic Cryptography, WAHC 2016.

This book presents the peer-reviewed proceedings of the 5th International Conference on Intelligent Computing and Applications (ICICA 2019), held in Ghaziabad, India, on December 6–8, 2019. The contributions reflect the latest research on advanced computational methodologies such as neural networks, fuzzy systems, evolutionary algorithms, hybrid intelligent systems, uncertain reasoning techniques, and other machine learning methods and their applications to decision-making and problem-solving in mobile and wireless communication networks.

Blockchain technology has certainly been hyped over the past few years, but when you strip all of that away, what can actually do with it? This book is a collection of articles that provide an introduction to Ethereum, an open source platform that's based based on blockchain. It enables developers to build and deploy decentralized applications that can be relied on to work without fraud, censorship or interference from third parties. We start off by explaining what blockchain is and how it works, and also look at some potential practical applications for blockchain technology. We then move on to looking at the Ethereum platform specifically. Far more than just a cryptocurrency or smart contracts platform, Ethereum is becoming an entire ecosystem for building decentralized applications.
