DECENTRALIZED ARCHITECTURES IN IOT DATA SHARING USING BLOCKCHAIN TECHNOLOGY

The development of IoT applications generally relies on centralized architectures, whether they use solutions based on cloud or on premises environments, usually operated by a single entity. However, recent technologies and the increasing number of interconnected intelligent devices are driving new approaches, the essential requirements being scalability and fault-tolerance. This work studies an alternative concept based on a decentralized architecture useful in several scenarios and focuses on available technologies for potential practical implementations.
