Her ne kadar Bitcoin ile tanınmaya başlasa da bu teknoloji, her geçen gün yeni bir uygulama alanı ile adından söz ettirmektedir. Güvenliğin son derece önemli olduğu bir sistemdir. Bu sebeple blok zincir teknolojisinde yapılan her işlemin doğrulanması gerekir, bunun için de mutabakat protokolleri kullanılır. Bu çalışmada, en yaygın olarak kullanılan protokollerden kapsamlı bir şekilde bahsedilmiştir. KW - Blockchain KW - KW - Mutabakat Protokolleri KW - KW - Bitcoin N2 - Blockchain technology, which has reached a popular position in the financial world with crypto currencies, is expressed as a distributed system that ends the central structure. Although it started to be known with Bitcoin, this technology is making a name for itself with a new application area every day. It is a system where security is extremely important. For this reason, every transaction made in blockchain technology must be verified, and consensus protocols are used for this. In this study, the most commonly used protocols are comprehensively mentioned. CR - Gökhan, Ü. N. A. L., & Uluyol, Ç. (2020). Blok zinciri teknolojisi. Bilişim Teknolojileri Dergisi, 13(2), 167-175.
