Smart City Ecosystem Using Blockchain Technology

Given the continuous development of urban areas, integrated policies are needed to improve the lives of urban residents by implementing integrated, interoperable and secure electronic services. Public administrations recognize the potential of blockchain in solving the problems of local communities. Blockchain, initially perceived through its association with cryptocurrency bitcoin, offers an innovative perspective on how smart cities can be organized and a more transparent economic model for resource management. This study analyses how blockchain technology-based services can contribute to the development of smart cities and proposes a Smart City ecosystem model based on SSI (Self-Sovereign Identity) authentication model and smart contracts between entities, citizens and administrations. It also overviews the domains in which this technology can be used. The results can be a starting point for the development of local initiatives for using the blockchain as a platform for communications and transactions in the public sector.
