Book SynopsisThis thought-provoking book challenges the way we think about the regulation of cryptoassets based on cryptographic consensus technology. Bringing a timely new perspective, Syren Johnstone critiques the application of a financial regulation narrative to cryptoassets, questions the assumptions on which it is based, and considers its impact on industry development.Providing new insights into the dynamics of oversight regulation, Johnstone argues that the financial narrative stifles the 'New Prospect' for the formation of novel commercial relationships and institutional arrangements. The book asks whether regulations developed in the 20th century remain appropriate to apply to a technology emerging in the 21st, suggesting it is time to think about how to regulate for ecosystem development. Johnstone concludes with proposals for reform, positing a new framework that facilitates industry aspirations while remaining sustainable and compatible with regulatory objectives.Rethinking the Regulation of Cryptoassets will be an invaluable read for policy makers, regulators and technologists looking for a deeper understanding of the issues surrounding cryptoasset regulation and possible alternative approaches. It will also be of interest to scholars and students researching the intersection of law, technology, regulation and finance.Trade Review‘Prof. Johnstone’s book on the regulation of cryptoassets forces us to think twice about the way we try to regulate the digital economy. He challenges the habit of the regulators to push new disruptive ideas and instruments into old frames and concepts, and invites them to move out of their comfort zone. Rethinking the Regulation of Cryptoassets is a complete account of the challenges we face in developing a crypto-economy and proposes a coherent and sustainable regulatory framework that ensures both market efficiency and technological relevance.’ -- Eva Kaili, Chair of the STOA Committee, Rapporteur of the Blockchain Resolution of the European Parliament, Brussels‘Cryptographic consensus technology presents extraordinary market opportunities but also raises a host of vexing regulatory challenges. Rethinking the Regulation of Cryptoassets maps this complex terrain and charts a way forward, offering a novel approach to the regulatory enterprise to protect against abuses while fostering innovation. Johnstone brings considerable legal, financial, and technological sophistication to the task, and his analysis is at once rigorous and accessible. This book will become essential reading on the future of cryptoassets.’ -- Christopher Bruner, University of Georgia School of Law, US‘The crypto industry moves fast and requires regulatory frameworks that can cater to that pace. Prof. Johnstone brings forward a number of ideas that are worth reflecting on as crypto assets are definitely here to stay.’ -- Henri Arslanian, Global Crypto Leader and Partner, PwC‘Johnstone provides a refreshing way to think about the regulatory limits of applying the standard financial narrative to a technology that is globally programmable but locally valuable. His DBA (Determined-By-Architecture) framework may help align regulation with the borderless possibilities of mathematics.’ -- Pindar Wong, Chairman, VeriFi (Hong Kong) LtdTable of ContentsContents: About the author Foreword Preface Why cryptoasset regulation needs rethinking: an introduction PART I THE INITIAL JOURNEY Acquiring the tradition 2 Cypher fundamentals 3 Responses from the centre PART II THE PRIMARY ISSUES 4 Applying securities laws to cryptoassets 5 Regulatory building blocks and other concerns 6 Complexities in a developing technology PART III THE SECONDARY MARKET 7 An emerging market 8 Cryptoexchange models 9 The concept of an exchange 10 Regulatory concerns PART IV INFLUENCES AND CONSIDERATIONS 11 The ordering of progress 12 Ecosystem development 13 Incrementalism and paradigms PART V FUTURE DIRECTIONS 14 Responding to change 15 Proposals for policy development 16 The origin of cryptocommunity Suggested readings Postscript Index

Book SynopsisIn The Political Economy and Feasibility of Bitcoin and Cryptocurrencies Spencer J. Pack brings his authority as a scholar and advisor to this study of bitcoin and cryptocurrencies from the perspective of the history of economic thought. Major theorists analyzed in depth include Aristotle, Smith, Law, Marx, Keynes, Rothbard and Hayek, and the book draws extensively upon the ideas of Schumpeter, Galbraith and Sraffa.The book argues for reconceptualization of the basic microeconomic categories into rental, sale and financial asset prices along with a reconsideration of Keynes’ general theory to his special theory and Rothbard’s relationship to Rousseau. The author posits that intense theoretical and practical struggles will continue over who should control the quantity of money, the cause of the capitalist economy’s instability, and who or what is more dangerous: concentrated centers of private wealth and private enterprises or the contemporary state. He concludes that in terms of the quality of money, the cryptocurrency community is probably correct, with new forms of money potentially being better than sovereign fiat currency.The book’s relevance will appeal to members of the history of economic thought community, economic theorists, and political science and political theory scholars as well as to policy makers and members of the cryptocurrency community.Trade Review‘At a time when the history of economic thought is unfortunately neglected, it is refreshing to see this book in which Spencer Pack deals brilliantly with a critical contemporaneous and practical issue from the perspective of the history of economic thought. The analysis fills a big gap in the literature on bitcoin and cryptocurrencies.’ -- Imad Moosa, RMIT, AustraliaTable of ContentsContents: Preface PART I ESSENTIAL FOUNDATIONS: BEFORE THE FRENCH REVOLUTION 1.

Book SynopsisThe end of the 20th century witnessed an information revolution that introduced a host of new economic efficiencies. This economic change was underpinned by rapidly growing networks of infrastructure that have become increasingly complex. In this new era of global security we are now forced to ask whether our private efficiencies have led to public vulnerabilities, and if so, how do we make ourselves secure without hampering the economy. In order to answer these questions, Sean Gorman provides a framework for how vulnerabilities are identified and cost-effectively mitigated, as well as how resiliency and continuity of infrastructures can be increased. Networks, Security and Complexity goes on to address specific concerns such as determining criticality and interdependency, the most effective means of allocating scarce resources for defense, and whether diversity is a viable strategy. The author provides the economic, policy, and physics background to the issues of infrastructure security, along with tools for taking first steps in tackling these security dilemmas. He includes case studies of infrastructure failures and vulnerabilities, an analysis of threats to US infrastructure, and a review of the economics and geography of agglomeration and efficiency. This critical and controversial book will garner much attention and spark an important dialogue. Policymakers, security professionals, infrastructure operators, academics, and readers following homeland security issues will find this volume of great interest.Trade Review'The world is growing more interconnected every day, spun with fiber optic cable, electric power lines, transportation and water networks. Gorman provides a detailed analysis of the pattern of telecommunications networks and their interrelationships with other infrastructure. The work is truly interdisciplinary in scope, and provides planners, policy makers, security analysts, and infrastructure managers and educators in all of these fields with an invaluable resource in terms of a rich database, a methodology, and process for assembling, analyzing and portraying information on key infrastructure assets. This work emphasizes space and place in understanding interconnectivity of physical infrastructure, integrating policy and geography as well as providing an important complement to engineering approaches to interconnected infrastructure. He presents the readers with a broad set of questions and how they can be addressed about threats, risk and vulnerability and policy options for their reduction. This is a rare book of its kind, and joins a growing literature on how complexity is a key factor in understanding and setting policies for the services upon which our society depends.' -- Rae Zimmerman, New York University, US'The concepts of Critical Infrastructure Protection are radically redefining the relationship between the public and private sectors in terms of both our national and economic security. Networks, Security and Complexity is a worthy contribution in defining and advancing many of these concepts. The author is among the vanguard of rising young scholars who will assist this nation in thinking through the significant security challenges faced in the age of information and asymmetric threat.' -- John A. McCarthy, George Mason University School of Law, US'This volume on complex networks opens surprising perspectives for the interested reader, either a scientist or a policymaker. It describes and analyzes in a convincing way the significance of critical infrastructures, be it internet or transport connections. Due insight into the existence and emergence of such infrastructures is a prerequisite for an effective security policy. This study presents a model-based, operational framework for identifying critical domains in dynamic networks. The various concepts are illustrated by means of empirical case examples.' -- Peter Nijkamp, VU University Amsterdam, The NetherlandsTable of ContentsContents: 1. Setting the Stage 2.

Book SynopsisThis textbook is a concise introduction to the basic toolbox of structures that allow efficient organization and retrieval of data, key algorithms for problems on graphs, and generic techniques for modeling, understanding, and solving algorithmic problems. The authors aim for a balance between simplicity and efficiency, between theory and practice, and between classical results and the forefront of research. Individual chapters cover arrays and linked lists, hash tables and associative arrays, sorting and selection, priority queues, sorted sequences, graph representation, graph traversal, shortest paths, minimum spanning trees, optimization, collective communication and computation, and load balancing. The authors also discuss important issues such as algorithm engineering, memory hierarchies, algorithm libraries, and certifying algorithms. Moving beyond the sequential algorithms and data structures of the earlier related title, this book takes into account the paradigm shift towards the parallel processing required to solve modern performance-critical applications and how this impacts on the teaching of algorithms. The book is suitable for undergraduate and graduate students and professionals familiar with programming and basic mathematical language. Most chapters have the same basic structure: the authors discuss a problem as it occurs in a real-life situation, they illustrate the most important applications, and then they introduce simple solutions as informally as possible and as formally as necessary so the reader really understands the issues at hand. As they move to more advanced and optional issues, their approach gradually leads to a more mathematical treatment, including theorems and proofs. The book includes many examples, pictures, informal explanations, and exercises, and the implementation notes introduce clean, efficient implementations in languages such as C++ and Java.Trade Review“The style of the book is accessible and is suitable for a wide range of audiences, from mathematicians and computer scientists to researchers from other fields who would like to use parallelised approaches in their research.” (Irina Ioana Mohorianu, zbMATH 1445.68003, 2020)Table of ContentsAppetizer: Integer Arithmetic.- Introduction.- Representing Sequences by Arrays and Linked Lists.- Hash Tables and Associative Arrays.- Sorting and Selection.- Priority Queues.- Sorted Sequences.- Graph Representation.- Graph Traversal.- Shortest Paths.- Minimum Spanning Trees.- Generic Approaches to Optimization.- Collective Communication and Computation.- Load Balancing.- App. A, Mathematical Background.- App. B, Computer Architecture Aspects.- App. C, Support for Parallelism in C++.- App. D, The Message Passing Interface (MPI).- App. E, List of Commercial Products, Trademarks and Licenses.

Book SynopsisDieses Lehrbuch behandelt im ersten Teil schwerpunktmäßig technische Maßnahmen, die den Schutz personenbezogener Daten sicherstellen. Dazu werden grundlegende Verfahren der Anonymisierung und der Gewährleistung von Anonymität im Internet (z. B. Tor) vorgestellt. Das Buch gibt einen Überblick über gängige Verfahren des Identitätsmanagements (z. B. OpenID Connect) und die in elektronischen Ausweisdokumenten (z. B. im Personalausweis) verwendeten Sicherheitsmaßnahmen. Die Datenschutz-Garantien der vermittelten Ansätze werden im Detail behandelt. Im Bereich des World Wide Web erfährt der Leser, wo die Probleme aus Sicht des Datenschutzes liegen und wie diese Lücken geschlossen werden können. Anonyme Bezahlverfahren und eine Untersuchung von Bitcoin runden den technischen Teil des Buches ab. Der Leser lernt Ansätze aus der Praxis kennen, um so je nach Anforderungen in der Systementwicklung das passende Verfahren auswählen zu können.Im zweiten Teil werden die Grundlagen des Datenschutzrechts behandelt. Denn technische Maßnahmen sollen unerlaubte Datenverarbeitung verhindern; das Recht bestimmt, welche Datenverarbeitungen erlaubt sind. Ohne Kenntnisse im Datenschutzrecht können technische Maßnahmen nicht richtig implementiert werden. Zum besseren Verständnis erfolgt ein Überblick über die Rechtsordnung insgesamt, in die das Datenschutzrecht eingeordnet wird. Betrachtet werden die europäische und die verfassungsrechtliche Dimension des Datenschutzes. Der Schwerpunkt liegt auf den Regelungen der Datenschutz-Grundverordnung. Dabei werden auch besonders häufig vorkommende und Fragen aufwerfende Verarbeitungssituationen wie das Webtracking erörtert. Beispielhaft werden datenschutzrechtliche Fälle bearbeitet.Trade Review“... Im rechtlichen Teil ist hervorzuheben, dass ... Grundlagen des Rechtsverständnisses zielgruppenbezogen für Informatikerinnen und Informatiker dargestellt werden. ... Es bildet die technischen Themen umfassend ab und bietet für das rechtliche Verständnis aktueller Fragestellungen eine solide Grundlage.” (Rudi Kramer, in: AWV-Informationen, 14.
