New Means of Transportation: Science and Tech Achievements
The Internet of Things (IoT) industry is continuously growing, leading to more IoT sensors being placed in smart cities. As the number of IoT sensors is growing, it is increasingly important to find ways to maximize the value of the data generated by those sensors. One way to increase the value of the data and the efficiency of the operations, whilst at the same time achieve economies of scale and reduced costs, is to share the available data. At the same time, an increasing number of people and corporations are expressing their interest in the technology of blockchain. The creation of the blockchain marks the time when we start building distributed peer-to-peer networks consisting of non-trusting members that interact with each other without a trusted intermediary but in a verifiable manner.
We will present a decentralized application (DApp) based on blockchain technology for sharing IoT sensors’ data, and demonstrate various challenges addressed during the development process. The application combines blockchain and IoT technologies and operates through smart contracts that are executed on the Ethereum blockchain. The application is a platform for sharing measurements of sensors, acting as a marketplace for IoT data and applying an innovative Sensing-as-a-Service (S2aaS) business model.
