A Survey on Blockchain Security
Navid Khoshavi, William Francois, Arman Sargolzaei, Harish Chintakunta · 2019
The blockchain is a revolutionary concept whose premise has been adopted by numerous industries. Applications of the blockchain have single handily driven an age of innovations. There has been a rapid race to use the blockchain to replace old centralized institutions and measures thereby greatly reducing the inefficiency. In this paper, we will survey some unique blockchain implementation measures to update and innovate inefficient sectors in different industries. We also review the security implementations inherent to blockchain along with upgrades done by specific researchers. The blockchain, while it does improve security is not attack proof. We will then discuss attack vectors that apply specifically to the blockchain.
