About the Technology
Imagine unbreakably secure applications that handle personal and business transactions without any central agency controlling the process. Decentralized applications, or Dapps, do just this, shifting power to users. The Ethereum blockchain platform provides the tools you need to build Dapps, including an innovative "smart contracts" model and Solidity, a Dapp-aware JavaScript-like programming language.
About the Book
Building Ethereum Dapps teaches Dapps development on the Ethereum blockchain platform. You'll begin with a mental model of how Dapps operate, and then dive into designing and implementing smart contracts in Ethereum's Solidity language. You'll explore Ethereum smart contract development tools, like Truffle and Web3, and pick up best practices for design and security. Practical exercises throughout give you valuable hands-on experience.

Discover how blockchain will facilitate a new currency that will transcend space and time
Largely inspired by The Denationalization of Money by Fredrich Hayek, Money Without Boundaries' ideological foundation is also inspired by economists and thought leaders like Milton Friedman and Irving Fisher, advancements in capital markets over the past 50 years, and the convergence of old and new technologies. Author Thomas J. Anderson explains how blockchain acts as the filter and the glue, making it all possible.
Compared with other currencies, blockchain-managed money markets are more straightforward and transparent. It is easier to monitor, understand, and assess the quality of their "full-faith and credit." Money Without Boundaries shows how not only money, but also the process of borrowing and lending, will evolve to be conducted in a 100% trusted, secure, transparent, open architecture environment. Anderson begins with a history of money and discusses the rise of cryptocurrency, concluding with a comparison of decentralized money markets to all other alternatives.
Money without Boundaries:
- Demonstrates how blockchain technology allows full transparency
- Explains how blockchain makes it possible for money to be fully commoditized
- Explains how this fully market-based, decentralized, self-regulating system has vast implications throughout the global financial system
- Shows how everyone will benefit when they have the opportunity to compete on "full faith in credit"
If you are interested in cryptocurrency, money, monetary theory, or understanding how the applied uses of blockchain technology will change your everyday life, this is essential reading.

Описание: This book provides an overview of the latest developments on Blockchain technology and its applications. The internet has already made it possible to transfer information quickly and cheaply, without involving intermediaries, while Blockchain gives the same benefits for transferring value. The Internet is used to transfer words and images, while Blockchain is used for transactions. Essentially, Blockchain is a combination of two elements: a shared and distributed ledger with synchronized data spread over multiple sites, countries, and / or institutions, and a cryptography - a digital token with a monetary value. This technology could have a huge impact on the value chain in our society. This impact includes efficiency, transparency, ownership, value (transfer), automation, and service provision. To understand the world of blockchain, we need to understand the innovation of the currency Bitcoin in 2009, that was built on Blockchain technology. Bitcoin is a combination of four individual elements: (1) cryptography, (2) a peer-to-peer network, (3) an open source protocol and (4) a shared ledger. This makes it a phenomenon that people have been enthusiastic about. This book is comprised of chapters written by experts on Blockchain from Austria, Brazil, China, Croatia, Georgia, Germany, Italy, Netherlands, Slovenia, Spain, and Switzerland, on the following topics: (1) Blockchain and the Agenda 2030 by Danielle Mendes Thame Denny, (2) Application of Blockchain Technology in the Field of E-Government Services by Jiarui Zhang, (3) Can the Cybersecurity of Smart Building be Improved Using Blockchain Technology? by Ben van Lier, (4) Influence of Blockchain Applications and Digitalization on Real Estate by Jan Veuger, (5) Blockchain: Technology Looking For a Problem in Real Estate? by Jo Bronckers and Jan Veuger et al., (6) Real Estate Start-up Get a Brick by Wendel Hulsebos and Jan Veuger, (7) Blockchain: An Efficiency Solution For Housing Associations? by Michel Vonk, (8) Blockchain Applications in Support of the Energy Transition by Mieke Oostra and Jelle Rijpma, and (9) Many Keys of Blockchain for Real Estate by Esther Dekker. Many questions remain about Blockchain, including whether to continue looking at existing markets for applications of the technology, or at disruptive and innovative newcomers. Is Blockchain only a technological disruption or a real game changer? Will the entire value chain of the market embrace it? Confidence in Blockchain is certainly a precondition for guiding disruption where (new) companies use new technology to offer cheaper and superior alternatives in the market. However, the big question is, how quickly will Blockchain develop as well as all its applications? Stephen Hawking wrote in his book Brief Answers to the Big Questions about how we will shape the future (Hawking, 2018: p207): "In the same way that the internet, our mobile phones, medical imaging, satellite navigation, and social networks would have been incomprehensible to the society of only a few generations ago, our future world is beginning to be conceived. Information on its own will not take us there, but the intelligent and creactive use of it will."

This book addresses what software architects and developers need to know in order to build applications based on blockchain technology, by offering an architectural view of software systems that make beneficial use of blockchains. It provides guidance on assessing the suitability of blockchain, on the roles blockchain can play in an architecture, on designing blockchain applications, and on assessing different architecture designs and tradeoffs. It also serves as a reference on blockchain design patterns and design analysis, and refers to practical examples of blockchain-based applications.
The book is divided into four parts: Part I provides a general introduction to the topic and to existing blockchain platforms including Bitcoin, Ethereum, and Hyperledger Fabric, and offers examples of blockchain-based applications. Part II focuses on the functional aspects of software architecture, describing the main roles blockchain can play in an architecture, as well as its potential suitability and design process. It includes a catalogue of 15 design patterns and details how to use model-driven engineering to build blockchain-based applications. Part III covers the non-functional aspects of blockchain applications, which are cross-cutting concerns including cost, performance, security, and availability. Part IV then presents three detailed real-world use cases, offering additional insights from a practical perspective. An epilogue summarizes the book and speculates on the role blockchain and its applications can play in the future.
This book focusses on the bigger picture for blockchain, covering the concepts and technical considerations in the design of blockchain-based applications. The use of mathematical formulas is limited to where they are critical. This book is primarily intended for developers, software architects and chief information officers who need to understand the basic technology, tools and methodologies to build blockchain applications. It also provides students and researchers new to this field an introduction to this hot topic.
