Abstract
Son yıllarda özellikle Bitcoin kripto parasının finansal alanda yapmış olduğu sansasyonel çıkış ile birlikte, Bitcoin’in altyapısındaki teknoloji olmasının da etkisiyle blokzincir teknolojisi giderek popüler hale gelmiştir. Blokzincir, tüm işlemlerin bloklar üzerinde şifrelenerek tutulduğu, alıcı ve satıcı tarafların herhangi bir üçüncü tarafın onaylamasına gerek olmaksızın kendi aralarında güvenli bir şekilde alışveriş yapmasına olanak tanıyan merkezi olmayan işlemsel veritabanı teknolojisidir. Bu işlemsel veri tabanı teknolojisinde tüm işlemler, sistemdeki kullanıcılara açık olan “Dağıtık (Açık) Defter” adı verilen bir yapıda kayıt altına alınır. Geleneksel yaklaşımda (merkezi veritabanı), veritabanı üçüncü bir tarafça kontrol edilirken, Blokzincir yaklaşımında veri tabanının birer kopyası tüm katılımcılarda bulunur. Böylelikle, verilerin bozulması ve tahrip edilmesi önlenir. Güvenlik, aracısız işlem, şeffaflık gibi avantajlar Blokzincir teknolojisini çekici kılmakta, birçok teknoloji şirketinin yatırım yapmasına ve mevcut sistemlerini blokzincir teknolojisi ile değiştirme eğilimi göstermesine sebep olmaktadır. Tüm bu avantajların temelinde ise blokzincir teknolojisinin sahip olduğu mimari yapısı yer almaktadır. Bu çalışmada blokzincir ağ mimarisi, kriptografik blok anahtarı yapısı ve fikir birliği yapısının bütüncül olarak blokzincir yapısı olarak ele alınması; bu yapının sağladığı avantajları ve ortaya çıkarttığı fırsatlar değerlendirilecektir.

Abstract
In recent years, especially with the sensational breakthrough of Bitcoin cryptocurrency in the financial field, blockchain technology has become increasingly popular with the effect of being the technology in the infrastructure of this cryptocurrency. Blockchain is a decentralized transactional database technology where all transactions are kept encrypted on blocks, allowing buyers and sellers to securely exchange transactions between themselves without the need for any third-party approval. In this transactional database technology, all transactions are recorded in a structure called "Distributed (Open) Ledger" that is open to users in the system. In the traditional approach (central database), the database is controlled by a third party, while in the Blockchain approach, all participants have a copy of the database. Thus, data corruption and destruction are prevented. Advantages such as security, agentless processing, and transparency make Blockchain technology attractive, causing many technology companies to invest and tend to replace their existing systems with blockchain technology. On the basis of all these advantages, there is the architectural structure of blockchain technology. In this study, the blockchain network architecture, cryptographic block key structure, and consensus structure will be considered as a blockchain structure, the advantages and opportunities of this structure will be evaluated.
