Smart city IoT is responsible for communicating system-critical data about urban infrastructure that keeps our modern cities functioning. Today, IoT devices lack commu- nication protocols with data integrity as a priority. Without data integrity, smart city infrastructure is at risk of actuating urban environments on compromised data. Attackers can use this IoT communication flaw to wage cyber-physical attacks on Smart Cities. We designed and developed an integrity-first communication protocol for IoT that is distributed and scalable based on the Ethereum blockchain. Our light client ensures data communication integrity for systems that require it most.

Description	Smart city IoT is responsible for communicating system-critical data about urban infrastructure that keeps our modern cities functioning. Today, IoT devices lack commu- nication protocols with data integrity as a priority. Without data integrity, smart city infrastructure is at risk of actuating urban environments on compromised data. Attackers can use this IoT communication flaw to wage cyber-physical attacks on Smart Cities. We designed and developed an integrity-first communication protocol for IoT that is distributed and scalable based on the Ethereum blockchain. Our light client ensures data communication integrity for systems that require it most.
