How to Design Secure and Attack Resilient Blockchain Applications

• Format: ePub

Produktbeschreibung

Learn to secure, design, implement, and test tomorrow's blockchain applications.

Blockchain Application Security guides readers through the architecture and components of blockchain, including protocols such as Bitcoin and beyond, by offering a technical yet accessible introduction. This resource is ideal for application architects, software developers, security auditors, and vulnerability testers working on enterprise blockchain solutions. It bridges the gap between theory and implementation, providing actionable guidance on protecting decentralized systems while capitalizing on their innovative benefits.

Blockchain Application Security covers the essentials, from the fundamentals of distributed ledgers, consensus algorithms, digital wallets, smart contracts, privacy controls, and DIDs, to designing secure dApp architectures with component-level threat analysis and resilient APIs, token transactions, digital exchanges, and identity models. It features a complete lifecycle example for securing a DeFi lending and borrowing platform, along with practical walkthroughs for smart contract development, AWS-integrated blockchain systems, frontend/API integration, and code auditing.
