Blokzincir Tabanlı E-Ticaret: Bir Değerlendirme

Öz

Elektronik ticaret, son yıllarda yaşanan teknolojik gelişmeler, tüketici tercihlerindeki değişimler ve COVID 19 salgınının etkisi nedeniyle öngörülerin çok daha ötesinde büyüme yaşayan bir sektör haline gelmiştir. E-ticaret, taraflara sunduğu faydalar ile fiziki mağazaları ikinci plana atarken, geleneksel işletmelerden farklı olarak kendine özgü yeni problemlerin ortaya çıkmasına neden olmuştur. Blok zincir teknolojisi, adem-i merkezi ve üçüncü taraf aracılara ihtiyaç duymayan yapısı ve gizlilik, değişmezlik, güvenlik, şeffaflık, denetlenebilirlik gibi özellikleri ile e-ticaret sektöründe karşılaşılan sorunların çözümünde umut vaat eden önemli bir alan olarak karşımıza çıkmaktadır. Blokzincirin e-ticarete sunabileceği faydalar, daha düşük maliyetler, daha şeffaf ve güvenilir ödeme süreçleri, daha yüksek veri gizliliği ve güvenliği, daha etkin tedarik zinciri ve itibar sistemleri olmak üzere beş başlık altında incelenmiştir. Yapılan çalışma ile blokzincirin sahip olduğu bu özellikleri sayesinde e-ticaret faaliyetlerini yeniden şekillendirebileceği ve e-ticaret sektörünün gelişimini hızlandırarak kârlılığını arttırabileceği sonucuna ulaşılmıştır. Bu doğrultuda blokzincir tabanlı e-ticaret platformlarının mevcut e-ticaret platformlarını arka plana itebileceği düşünülmektedir.

Blockchain-Based E-Commerce: An Evaluation

Öz

The e-commerce sector has grown beyond predictions with the help of the most recent technological developments, changes in consumer preferences, and the COVID-19 pandemic. E-commerce activities assume a subsidiary role of brick-and-mortar shops with the benefits it offers to all parties, which have also resulted in new problems such as privacy, security, transparency, and costs, unlike traditional businesses. Blockchain technology is among the promising technologies in solving the problems of the e-commerce sector with its decentralized structure that does not require third-party intermediaries, and its features (such as privacy, immutability, security, transparency, and auditability). In this study—which examines, under five titles, the benefits that blockchain can offer to e-commerce—it is concluded that blockchain can reshape e-commerce activities by enabling integrated e-commerce systems that include all parties and offering low transaction costs, high transaction speed, traceability of transactions, strong security standards, and low risks. In this direction, blockchain-based e-commerce platforms can push existing e-commerce platforms into the background.
