Blockchain Nedir?

Blok Zinciri Mid

Blockchain, Türkçe’de “blok zinciri” olarak da bilinir ve verilerin şeffaf, güvenli ve değiştirilemez şekilde saklandığı dijital bir kayıt sistemidir. Her yeni veri, bir “blok” olarak zincire eklenir ve bu bloklar kırılması neredeyse imkânsız bir yapıyla birbirine bağlıdır.En basit hâliyle, blockchain bir nevi dağıtık dijital defter olarak düşünülebilir. Bu yapı sayesinde merkezi bir otoriteye ihtiyaç kalmadan, kullanıcılar arasında güvenli işlem yapılabilir.

Blockchain Nasıl Çalışır?

  • Her işlem, bir blok olarak oluşturulur.

  • Bu blok, zaman damgası ve önceki bloğun kimliğini içerir.

  • Blok doğrulandıktan sonra zincire eklenir ve tüm ağ tarafından görünür hale gelir.

  • Bir bloğun içeriği değiştirilemez çünkü zincirin tamamı etkilenir; bu da veri güvenliğini sağlar.

Blockchain Nerelerde Kullanılır?

  • Kripto paralar: Bitcoin, Ethereum gibi dijital paralar blockchain altyapısını kullanır.

  • Akıllı kontratlar: Şartlara göre otomatik çalışan, blockchain üzerinde kayıtlı sözleşmelerdir.

  • Tedarik zinciri yönetimi: Ürünlerin üretimden teslimata kadar izlenmesini sağlar.

  • Oylama sistemleri, dijital kimlik, NFT, sağlık kayıtları gibi alanlarda da kullanımı yaygındır.
