With the advancement of technology, online transactions have been on the rise. These include Bitcoin, a digital currency with no physical existence. When one engages in an online transaction, one expects that their information is secure and confidential. However, the increment of such systems has opened chances for information attacks by malicious users (Bourgeois et al., 2019). With Bitcoin, various measures have been installed to ensure top-notch information security; however, the mining and transactions are not completely secure, so they may be a target for hackers (Gallaugher, 2015). Therefore, Bitcoin is vulnerable to information security threats such as double spending, distributed denials of service (DDoS), and selfish mining.
