Using blockchain platforms to build decentralized applications

This study aims to analyze the development and implementation of decentralized applications (DApps) on blockchain platforms. The research employs a comprehensive approach, examining architectural features of popular blockchain platforms, security aspects, and risk management strategies. A practical implementation of a supply chain management DApp on Ethereum is presented, detailing key development stages such as smart contract design, data storage integration, and user interface creation, alongside an analysis of associated technical, economic, and regulatory challenges. The study reveals that while DApps offer significant advantages in transparency, censorship resistance, and immutability of data, they encounter significant barriers in scalability due to limited transaction throughput, challenges in delivering user-friendly interfaces, and uncertainty in regulatory compliance across multiple jurisdictions. The research contributes to the field by providing an in-depth analysis of current DApp development practices, innovative approaches to identity and access management, and strategies for mitigating operational, financial, and reputational risks. The findings suggest that further interdisciplinary research and industry-academia collaboration are crucial for realizing the full potential of DApps in transforming various sectors of the digital economy.
