Natural phenomena such as floods, storms, volcanic eruptions, earthquakes, landslides have affected our planet in an unpredictable way and the need for a proper disaster management  plan is crucial to overcome these challenges. Blockchain technology could help to improve communication between multiple parties, but that leaves the question of how best to protect information and data.

In this study, the authors have developed different models using blockchain network concepts and utilised its ability to store information and data safely and making the transaction secure and anonymous. These models are further utilised in the process of providing better communication between two parties during a disastrous situation and using these models in order to provide secure storage of
private information by the respective organisation.

They have also focused on the ways to provide more efficient National Security using emerging techniques like blockchain.
More specifically, this study is interested in the following research questions:

• What is blockchain and how does it work?
• Can a blockchain network provide better disaster management?
• Can a blockchain network be used for safer storage of private information and reduce the possibilities of identity theft?
• Can blockchain network and technology be used to provide better national security in terms of border security and the weapon of mass destruction?
