Blockchain is a technology developed for the tamper-proof storage of data. The more effective use of blockchain technology and the emergence of decentralized applications have been realized through smart contracts. However, smart contracts cannot receive data from outside the blockchain they are working on. This problem limits the emergence of projects for the solution of real-life problems. Blockchain oracles fill the communication gap between on- and off-blockchain data.
In this research, served information about blockchain technology and smart contracts are given. Then, Blockchain oracles were explained, and information was given about the Blockchain oracle technology architecture, academic study statistics, and major commercial initiatives in this field. In the last section of the research, a case study was demonstrated for the creation of the Blockchain oracles system. In the research, the architecture that constitutes the pilar of a system necessary for transferring data into and out of the blockchain has been revealed theoretically and practically.

Blok zincir, verinin kurcalamaya karşı güvenli olarak saklanmasına yönelik geliştirilmiş bir teknolojisidir. Blok zincir teknolojisinin daha etkin kullanılması ve merkezi olmayan uygulamaların ortaya çıkışı akıllı sözleşmeler aracılığı ile gerçekleşmiştir. Ancak akıllı sözleşmeler üzerinde çalıştıkları blok zincir dışından veri alamamaktadır. Bu problem gerçek yaşam problemlerinin çözümü adına projelerin ortaya çıkışını sınırlandırmaktadır. Blok zincir ulakları blok zincir içi ve dışı verileri arasındaki iletişim boşluğunu doldurmaktadır.
Bu çalışmada blok zincir teknolojisi ve akıllı sözleşmeler hakkında bilgi verilmiştir. Ardından Blok zincir ulakları tanıtılmış olup, ulak teknolojisi mimarisi, akademik çalışma istatistiği, bu alandaki belli başlı ticari girişimler hakkında bilgi verilmiştir. Çalışmanın son bölümünde blok zincir ulak sisteminin oluşturulması için örnek çalışma yapılmıştır. Yapılan çalışmada blok zincir içine ve dışına verilerin aktarılması için gerekli bir sistemin temel taşını oluşturan mimari teorik ve uygulamalı olarak ortaya koyulmuştur.
