Contribution

It introduces a modular, scalable blockchain architecture with a context-aware interface to improve smart city processes and stakeholder communication.

Findings

Blockchain enables secure, anonymous data collection.

The architecture improves scalability and stakeholder integration.

Enhanced security and data integrity in smart city applications.

Abstract

The combination between innovative topics and emerging technologies lets researchers define new processes and models. New needs regard the definition of modular and scalable approaches, with society and environment in mind. An important topic to focus on is the smart city one. The use of emerging technologies lets smart cities develop new processes to improve services offered from various actors, either industries or government. Smart cities were born to improve quality of life for citizens. To reach this goal, various approaches have been proposed, but they lack on a common interface to let each stakeholder communicate in a simple and fast way. This paper shows the proposal of an architecture to overcome the actual limitations of smart cities: it uses Blockchain technology as a distributed database to let everyone join the network and feel part of a community. Blockchain can improve processes development for smart cities. Scalability is granted thanks to a context-aware approach: applications do not need to know about the back-end implementation, they just need to adapt to an interface. With Blockchain, it is possible to collect data anonymously to make some statistical analysis, to access public records to ensure security in the city and to guarantee the origin of products and energy.
