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.

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."

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.

Описание: High-performance computing (HPC) describes the use of connected computing units to perform complex tasks. It relies on parallelization techniques and algorithms to synchronize these disparate units in order to perform faster than a single processor could, alone. Used in industries from medicine and research to military and higher education, this method of computing allows for users to complete complex data-intensive tasks. This field has undergone many changes over the past decade, and will continue to grow in popularity in the coming years.Innovative Research Applications in Next-Generation High Performance Computing aims to address the future challenges, advances, and applications of HPC and related technologies. As the need for such processors increases, so does the importance of developing new ways to optimize the performance of these supercomputers. This timely publication provides comprehensive information for researchers, students in ICT, program developers, military and government organizations, and business professionals.
