Business applications are accessible through networks (public or private), and these applications are sets of code that have value until they are accessible, which is when they are needed. Blockchain is a software application running on the cloud that keeps its value until it is not broken or disturbed. For users, the face of blockchain is simply a decentralized application (dApp), and in order to keep it available all of the time, both the frontend and the backend of the system should run seamlessly.
On-time and reliable access to information resembles availability. Cyberattacks such as DDoS cause huge disruption to internet services and result in websites becoming inaccessible, which costs businesses a lot of money. The decentralized nature of blockchain makes it harder to disrupt these applications.
