Most, if not all, digital systems are exposed to cyber security risks, thus, it is vital to innovate solutions to protect them and record proof of possible attacks.
One of the possible solutions would be using blockchain and distributed ledger technologies (DLT). The large-scale diffusion of Internet of Things (IoT) systems provides plentiful state-of-the-art solutions like e-healthcare, smart homes, e-voting, smart surveillance, e-democracy, smart industries, smart cities, e-commerce and smart grids.
Consequently, this has led to a significant increase in the threats that exploit the vulnerabilities of IoT devices. So, it is very crucial to engineer powerful cyber security solutions that are able to protect vulnerable devices and create models of digital forensics capable of recovering evidence of possible attacks.
