Blockchain Based Smart Card for Smart City

Abstract

We are living in the age of various modern technologies and Blockchain is one of the newest among them. Smart contract are used with Blockchain as an add on which brings automation in application. Smart card are also used nowadays widely to access smart services in various domains. Since the vast majority of people nowadays do not want to carry a lot of cards with them at all times. As a result, we came up with a solution to this conundrum. A single Card, which will function as the key card for all municipal services, will serve as the core hub for all of this decentralization. Also planned is the development of a Cryptocurrency wallet, which will allow smart cities to access anything inside the Blockchain Network directly from peer to peer. There will be no intermediates who will be able to access any citizen’s information or data; yet, if an event happens, such as criminal activity, there will be no one to blame. Using blockchain technology, law enforcement will be able to follow down the perpetrators of these crimes since all timestamps will be saved on our platform. Because of this, smart cities will be less prone to criminal activity in general. We can ensure a more efficient smart city by using blockchain technology. Therefore, people will have a greater sense of security at every level of service where Card will play a vital part. Finally, we can say that a Blockchain-based Smart Card will serve as a one-stop solution for all of humanity. Consequently, we don’t have to be worried with all of the services that are offered in any certain place. Life will be far better than it has ever been in the past. Blockchain technology, which was initially introduced in 2008 and is based on cryptography, is the fundamental technology that underpins the bitcoin cryptocurrency. Initially, it was exclusively utilized by the cryptocurrency bitcoin.
