Foundations of Blockchain
Learn the foundations of blockchain technology - its core concepts and algorithmic solutions across cryptography, peer-to-peer technology, and game theory. Key FeaturesLearn the core concepts and foundations of the blockchain and cryptocurrenciesUnderstand the protocols and algorithms behind decentralized applicationsMaster how to architect, build, and optimize blockchain applicationsBook Description Blockchain technology is a combination of three popular concepts: cryptography, peer-to-peer networking, and game theory. This book is for anyone who wants to dive into blockchain from first principles and learn how decentralized applications and cryptocurrencies really work. This book begins with an overview of blockchain technology, including key definitions, its purposes and characteristics, so you can assess the full potential of blockchain. All essential aspects of cryptography are then presented, as the backbone of blockchain. For readers who want to study the underlying algorithms of blockchain, you’ll see Python implementations throughout. You’ll then learn how blockchain architecture can create decentralized applications. You’ll see how blockchain achieves decentralization through peer-to-peer networking, and how a simple blockchain can be built in a P2P network. You’ll learn how these elements can implement a cryptocurrency such as Bitcoin, and the wider applications of blockchain work through smart contracts. Blockchain optimization techniques, and blockchain security strategies are then presented. To complete this foundation, we consider blockchain applications in the financial and non-financial sectors, and also analyze the future of blockchain. A study of blockchain use cases includes supply chains, payment systems, crowdfunding, and DAOs, which rounds out your foundation in blockchain technology.

Elliptic Curve Digital Signature Algorithm in Theory and Practice
"Elliptic Curve Digital Signature Algorithm in Theory and Practice" "Elliptic Curve Digital Signature Algorithm in Theory and Practice" is an authoritative guide that offers readers a comprehensive exploration of ECDSA from fundamental principles to cutting-edge applications. The book begins with a detailed study of the algebraic underpinnings of elliptic curve cryptography, examining algebraic structures, coordinate systems, and the essential group laws that form the basis for secure cryptographic schemes. Through rigorous comparisons with classical algorithms like RSA and DSA, and an analysis of mathematical attacks and curve vulnerabilities, the work equips readers with a deep understanding of the theory that underlines the robust security offered by ECDSA. Building on these foundations, the text systematically covers digital signature schemes and the formal security models that define their resilience in the digital landscape. It provides a technical walkthrough of the ECDSA specification, including parameter selection, international standards compliance, point encoding, and the implementation nuances necessary for practical deployment. Comprehensive chapters address performance optimizations, defense mechanisms against side-channel and implementation-level attacks, and approaches for secure operation in constrained environments such as embedded and IoT devices. Additionally, the book demystifies advanced ECDSA variants and extensions, including threshold signatures, batching, aggregation techniques, and emerging trends like post-quantum and hybrid cryptographic systems. Completing the journey from theory to practice, this volume delivers an in-depth review of real-world deployments and key management strategies in diverse domains—ranging from secure communication protocols and blockchain platforms to hardware security modules and large-scale enterprise systems. Case studies and practical guidelines illuminate best practices for integration, auditability, compliance, and incident response. With a dedicated focus on testing, formal verification, continuous integration, and evolving research trajectories, this book is an indispensable resource for security professionals, implementers, and academics striving to navigate and contribute to the dynamic landscape of digital signatures and elliptic curve cryptography.
