Bitcoin kripto parasının finans alanında yapmış olduğu atak, borsada yeni bir rüzgarın esmesine neden olmuş ve birçok yeni kripto para biriminin ortaya çıkmasıyla kripto para piyasası yeni bir finans alanı haline gelmiştir. Blokzincir teknolojisi Bitcoin'in teknolojik altyapısı olsa da bilinirliği Bitcoin kadar yüksek değil. 1992 yılında bulunmasına rağmen ilk kullanımı 2008 yılında Bitcoin ile birlikte olmuş ve bu sebeple Bitcoin'in gölgesinde kalmıştır. Fakat; blokzincir teknolojisi olmadan Bitcoin sisteminin çalışması mümkün değildir. Bitcoin sahip olduğu merkezi olmayan yapı sayesinde, alıcı ve satıcıları doğrudan bir platformda buluşturmakta ve herhangi bir üçüncü tarafın katılımı olmadan güvenli bir şekilde alışverişlerini gerçekleştirmelerine imkan sağlamaktadır. Sistemde doğrulama ancak katılımcıların %50'sinden fazlasının onayı ile yapılabilmektedir. Böylece merkezi bir otoriteye ihtiyaç duyulmamasının yanı sıra herhangi bir siber saldırının başarılı olması neredeyse imkansız hale gelmektedir. Tüm bu avantajların yanı sıra blokzincir teknolojisi için ele alınması gereken bazı sorunlar da bulunmaktadır. Bunlar; verimsizlik, işlemlerde gecikme, boyut ve bant genişliği, bazı güvenlik açıkları, zincirlere yeni bir blok eklemek için kaynak israfı, kullanılabilirlik ve gizlilik olarak sıralanabilir. Bu yazımızda blokzincir teknolojisinde geliştirilmeye ihtiyacı olan bu hususları tartışacağız.

The Improvement needs in Blockchain Technology

Öz

Bitcoin's attack in finance has caused a new wind to blow in the stock market and with the emergence of many new crypto currencies, the crypto currency market has become a new financial area. Although Blockchain technology is the technological infrastructure of Bitcoin, awareness is not as high as Bitcoin. Despite it was found in 1992, its first use was in the shadow of Bitcoin, influenced by the fact that it was with Bitcoin in 2008. However, due to the features that it provides; Without Blockchain technology, the Bitcoin system would not work. As the dazzling offer of Bitcoin; through the decentralized structure, buyers and sellers can meet directly on a platform and make their purchases securely, without involvement of any third party. Verification in the system can only be done by approving by more than 50% of the participants. Thus, besides of no need for a central authority, it became almost impossible for any cyber attack to be successful. The continued success of Blockchain technology is vital for Bitcoin and other cryptographic currencies survival. Beside of all these advantages, there are some issues that need to be addressed for Blockchain technology. These can be listed as throughput, latency in processing, size and bandwidth, some security vulnerabilities, resource waste for adding a new block to chains, usability, and privacy. In this article, we will discuss these issues that need to be addressed for Blockchain technology.
