Decentralized Application (DApps)

Abstract

A Decentralized Application (DApp) is a distributed, open-source software application that runs on a peer-to-peer (P2P) blockchain network. DApps are emerging as a transformative force across various sectors, leveraging blockchain technology to create applications that operate autonomously, offer enhanced security and transparency, and function without a central authority. Common security issues with DApps include smart contract and blockchain vulnerabilities, phishing and social engineering attacks, and key management challenges. Mitigation strategies involve thorough code audits, formal verification, multi-signature wallets, and robust security frameworks. This chapter provides a detailed analysis of DApp security, focusing on theoretical aspects, architectural components, and specific vulnerabilities in smart contracts, oracles, blockchain protocols, front-end interfaces, and cross-chain interoperability mechanisms.
