BLOCKCHAIN TECHNOLOGY FOR SECURE AND TRUSTWORTHY DECENTRALIZED APPLICATIONS

Abstract

This study explores the complex world of blockchain-based decentralized applications (DApps), concentrating on security and trust mechanisms. The study detects and classifies security flaws in DApps, which include flaws in smart contracts, difficulties with consensus, including dangers of data manipulation. By contrasting reputation-based systems with token-based incentives, it investigates trust mechanisms and clarifies their effects on user behaviour. The study emphasizes the crucial part that blockchain integration plays in boosting DApp security by employing its built-in immutability, decentralization, and cryptographic characteristics. The benefits of blockchain are supported by empirical data and vivid case examples. The paper ends with advice for DApp creators that emphasizes secure development methods, thorough audits, as well as user education while also indicating potential directions for future research.
