Orthus: A Blockchain Platform for Smart Cities
blockchain, smart city, scalability.
Currently, blockchain has been widely used to store decentralised and secure transactions involving cryptocurrency (for instance, Bitcoin and Ethereum solutions). On the other hand, smart city applications are concerned about how data and services can be safely stored and shared. In this regard, this research investigates the use of blockchain and pinpoints a set of essential requirements to meet the needs of blockchain for the context of smart cities. Base on that, a platform named Orthus was proposed to support the use of blockchain in smart city initiatives focused on scalability. This master’s thesis demonstrated a case study about how to use the proposed platform in the context of the Natal Smart City Initiative, in Brazil, to handle land registration. Moreover, it also compares this platform with other implementations that use blockchain in different domains. Finally, this research confirms that use of blockchain technology has much to contribute to smart city solutions once it enables the creation of solutions in distributed networks being able to meet the demand of the entire population.
