Blockchain Nedir?

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.

What is calendar call spread?

Call calendar spread trading is an options trading strategy that seeks to lock in gains from the changing prices over time of two options contracts with different expiry dates. Call calendar spreads are formed when a trader buys or sells a longer-dated call contract and takes the opposite position in a shorter-dated contract with the same strike price at the same time. Call calendar spreads are sometimes known as time-spreads or horizontal spreads. They become more lucrative as expiration approaches because of the time decay from both option contracts.

Understanding the concept of an all-time high (ATH) in crypto

As the crypto market continues its powerful surge following the April 2024 Bitcoin halving, we’re witnessing breathtaking gains across a wide range of coins and tokens. The rally has reignited memories of past bull market frenzies, only this time, prices have already shattered previous records. Bitcoin, which set its former all-time high of around $68,742 on November 10, 2021, has since stormed past the $100,000 mark in late 2024 and reached over $123,000 in August 2025. With fear of missing out (FOMO) running high, traders are now asking not if the market can reclaim old highs, but how far this cycle can push the boundaries of what’s possible.
