Abstract

Blockchain technology, which succeeds in attracting attention after the
success of cryptocurrency, is a developing and popular subject of study. With
its decentralized structure, decentralized and indelible data recording,
encrypted block architecture, and data structure that does not allow tampering
by third parties, it is capable of solving many problems. Blockchain, a
supporting technology, is being tried to be integrated into many different
technologies. For this reason, in this article, in which areas blockchain
technology is used and what results are obtained were shared. Information about
the advantages and challenges of blockchain technology is shared. As a result
of the researches we have done, it has been determined which study areas
blockchain technologies can be applied in Turkey. As the application areas of
blockchain technology, banking applications, internet security, supply chain,
internet of objects, insurance, personal and public transportation, online data
storage, foundation and donation processes, voting processes, public
applications, health applications, energy management, intellectual property and
copyright rights applications, real estate and title deed applications, digital
identity, smart cities, smart contracts and legal compliance examination,
applications in the field of education were identified and the information
obtained was shared.

Blokzinciri Teknolojisi ve Türkiye’deki Muhtemel Uygulanma Alanları

Abstract

Kripto paraların elde ettiği
başarı sonrası dikkatleri üzerine çekmeyi başaran blokzincir teknolojisi,
gelişmekte olan ve popüler bir çalışma konusudur. Merkeziyetçi olmayan yapısı,
tek yönlü ve silinemez veri kaydı, şifrelenmiş blok mimarisi ve üçüncü
şahıslarca kurcalanmaya müsaade etmeyen veri yapısıyla birçok soruna çözüm
olacak niteliktedir. Destekleyici bir teknoloji olan blokzinciri, birçok farklı
teknolojiye entegre edilmeye çalışılmaktadır. Bu sebeple makalemizde blokzincir
teknolojisinin hangi alanlarda kullanıldığı ve ne gibi sonuçlar elde edildiği
araştırılmıştır. Blokzincir teknolojisinin sağladığı avantajlar ve karşılaştığı
zorluklar hakkında elde edilen bilgiler paylaşılmıştır. Yapmış olduğumuz
araştırmalar sonucunda blokzincir teknolojisinin Türkiye’de hangi alanlarda
uygulanabileceği belirlenmiştir. Blokzincir teknolojisinin uygulama alanları
olarak bankacılık uygulamaları, internet güvenliği, tedarik zinciri, nesnelerin
interneti, sigortacılık, kişisel ve toplu ulaşım, online veri saklama, vakıf ve
bağış işlemleri, oy verme süreçleri, kamu uygulamaları, sağlık uygulamaları,
enerji yönetimi, fikri mülkiyet ve telif hakkı uygulamaları, emlak ve tapu
uygulamaları, dijital kimlik, akıllı şehirler, akıllı sözleşmeler ve hukuki
uygunluklarının incelenmesi, eğitim alanında uygulamaları gibi on sekiz farklı
çalışma konusu tespit edilmiş ve edinilen bilgiler paylaşılmıştır.
