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.

Özet

Blokzincir teknolojisi, dağıtık defter mimarisi, kriptografik güvenlik mekanizmaları ve merkeziyetsiz çalışma prensipleri sayesinde son yıllarda önemli ölçüde dikkat çekmiştir. Finans, sağlık, eğitim, kamu hizmetleri ve tedarik zinciri yönetimi gibi farklı sektörlerde şeffaflık, veri bütünlüğü, güvenlik ve izlenebilirlik gibi avantajlar sunmasıyla, blokzincir tabanlı sistemler dijital dönüşüm süreçlerinin kritik bir bileşeni haline gelmiştir. Bu çalışma, blokzincir teknolojisinin temel bileşenlerini ve çalışma prensiplerini incelemekte; farklı alanlardaki güncel uygulamalarını analiz ederek bu uygulamaların sunduğu fırsatları ortaya koymaktadır. Ayrıca, ölçeklenebilirlik sınırlamaları, yüksek enerji tüketimi ve düzenleyici belirsizlikler gibi temel zorluklar değerlendirilmektedir. Son olarak, teknolojinin evrimi ve daha geniş ölçekte benimsenmesine ilişkin geleceğe yönelik perspektifler tartışılmaktadır. Çalışma, blokzincir teknolojisinin etkilerini ve yansımalarını bütüncül ve disiplinlerarası bir bakış açısıyla ele alan anlatısal bir derleme olarak tasarlanmıştır.
