IoT Meets Blockchain: Parallel Distributed Architecture for Data Storage and Sharing

The rapid development of Internet of Things technology has led to the sharp increase of the number of interconnected devices. A large amount of data is generated by large-scale loT devices. In this paper, we propose PDash with parallel distributed architecture, a scalable blockchain-based platform for loT data storage and sharing. PDash aims to solve the bottleneck problem of blockchain system: scalability, and makes it possible for users to keep ownership of their own data as well as share data securely with economic feedback. PDash integrates decentralized blockchain network and distributed storage network to achieve secure data storage, validation and sharing, and utilizes multiple encryption technologies to enable efficient interaction between two parallel distributed networks.
