Blockchain Technology: Applications, Challenges, and Future Perspectives Across Multiple Sectors

Abstract

Blockchain technology has attracted significant attention in recent years due to its distributed ledger architecture, cryptographic security mechanisms, and decentralized operational principles. By providing advantages such as transparency, data integrity, security, and traceability across diverse sectors including finance, healthcare, education, public services, and supply chain management, blockchain-based systems have become a critical component of digital transformation processes. This study examines the fundamental components and operational principles of blockchain technology and analyzes its contemporary applications across various domains, highlighting the opportunities these applications present. Furthermore, key challenges such as scalability limitations, high energy consumption, and regulatory uncertainties are evaluated. Finally, future perspectives regarding its evolution and broader adoption are discussed. The study is designed as a narrative review that provides a holistic and interdisciplinary assessment of the impacts and implications of blockchain technology.
