Abstract |
The Blockchain-based applications, nowadays, has gotten insanely popular. It is a race out there; everyone is trying to build his application on top of the blockchain. Certainly, that is due to its unique characteristics and design. However, such characteristics are not well suited to all applications of blockchain technology. Not merely alteration of the blockchain’s protocols would make it suitable, but rather redesigning its architecture is required to make it suitable for different applications. This paper describes the overview of blockchain technology in a very comprehensive manner, summarizes most of the popular attacks that surfaced against such a technology and the vulnerabilities exploited by them, which leads to design a better version of the blockchain that is well suited to the application in question. |
