BLOCKCHAIN TECHNOLOGY AND DECENTRALIZED FINANCE APPLICATIONS

Öz

Abstract: Blockchain technology is a distributed ledger architecture that allows us to manage user data and digital assets. Cryptocurrency systems, which are proposed based on blockchain architecture, and virtual economy and financial systems are gradually developing. The innovative side of blockchain architecture is that instead of a central server, it maintains a distributed ledger in the internet environment with a decentralized structure. Blockchain technology supports the emergence of innovative financial services in the field of finance with its robust architectural structure offered by mechanisms such as hash functions, asymmetric encryption, and consensus algorithms. In this study, the opportunities created by the services of decentralized finance that come with blockchain technology are evaluated with their difficulties and risks.

Blokzincir Teknolojisi ve Merkeziyetsiz Finans Uygulamaları

Öz

Blokzincir teknolojisi kullanıcı verilerini, dijital varlıkları yönetmemizi sağlayan dağıtık defter yapısında bir mimaridir. Blokzincir mimarisine dayalı bir yapı olarak önerilen kripto para sistemleri ile sanal ekonomi ve finans sistemleri giderek gelişmektedir. Blokzincir mimarisinin yenilikçi tarafı merkezi bir sunucu yerine, merkezi olmayan bir yapı ile verileri internet ortamında dağıtık bir defter yapısında tutmasıdır. Blokzincir teknolojisi özet fonksiyonlar, asimetrik şifreleme, tam mutabakat algoritmaları gibi mekanizmalarla sunduğu sağlam mimari yapısı ile finans alanında yenilikçi finansal hizmetlerin ortaya çıkmasını desteklemektedir. Bu çalışmada blokzincir teknolojisi ile gelen merkeziyetsiz finansın sunduğu hizmetlerin yarattığı fırsatlar zorlukları ile değerlendirilmektedir.
