THE DECENTRALIZED FINANCE (DEFI) ECOSYSTEM: A SYSTEMATIC REVIEW AND BIBLIOMETRIC ANALYSIS

Öz

This study aims to analyze research on decentralized finance (DeFi) using bibliometric methodology to evaluate trends and identify gaps in the literature. A detailed bibliometric analysis was conducted on 301 publications retrieved from the Web of Science (WoS) database using the keywords “(TS=("Decentralized Finance" OR "Defi")”. The distribution of publications, citation networks, author collaborations, and thematic concentrations were thoroughly examined. The findings reveal that DeFi plays a significant role in the adoption of cryptocurrencies and the transformation of financial systems. DeFi has the potential to serve as a viable alternative to the current banking system, drawing substantial academic interest in areas such as technological infrastructure, regulatory frameworks, and risk management.

MERKEZİYETSİZ FİNANS (DEFİ) EKOSİSTEMİ: SİSTEMATİK BİR İNCELEME VE BİBLİYOMETRİK ANALİZ

Öz

Bu makale, merkeziyetsiz finans (DeFi) alanındaki araştırmaları bibliyometrik metodolojiyle analiz ederek literatürdeki eğilimleri ve bilgi boşluklarını değerlendirmeyi amaçlamaktadır. Web of Science (WoS) veri tabanında “(TS=("Decentralized Finance" OR "Defi")” anahtar kelimesiyle taranan 301 yayının dağılımı, alıntı ağları, yazar işbirlikleri ve tematik yoğunlaşmaları detaylı bir şekilde incelenmiştir. Bulgular, DeFi’nin blokzincir teknolojisinin benimsenmesinde ve finansal sistemlerin dönüşümünde önemli bir rol oynadığını göstermektedir. Mevcut bankacılık sistemine uygulanabilir bir alternatif sunma potansiyeline sahip olan DeFi, teknolojik altyapı, düzenleyici çerçeveler ve risk yönetimi gibi kritik alanlarda yoğun akademik ilgi görmektedir.
