Blockchain Technology and Decentralized Finance: Theory and Practice in Cryptocurrency Creation

Blockchain technology represents a revolutionary concept in the field of digital economy, enabling security, transparency, and decentralization of data and transactions. This paper explores the fundamental principles of blockchain technology, the role of cryptocurrencies, and the development of decentralized finance (DeFi). It analyzes key differences between centralized and decentralized exchanges, as well as the significance of DeFi applications in the modern financial ecosystem. Additionally, through a case study, the paper presents the process of creating a new cryptocurrency—ELAB—including the implementation of a smart contract on the Binance Smart Chain network and token distribution. The main goal of the paper is to provide both theoretical and practical insights into the fundamental concepts of blockchain and its application in real-world systems. The study’s results demonstrate how cryptocurrencies can be utilized in various contexts, including the educational system, where gamification through digital tokens can enhance student engagement.
