New Advances in the Internet of Things

Abstract

Without a central authority, blockchains can easily enable the contractual states that are not controlled by anybody, so they can be trusted. In management oftransactions. Smart contracts stored on blockchains are self-executing ory space, which allow them to execute user-defined programs, e.g., smart contracts. (Internet of Things) devices have more powerful processing power and greater mem- addition, due to increasing improvements in processor and memory technology, IoT decrease many basic data analytics tasks’ execution time. Blockchain can be used as over the IoT network. The parallelism of large-scale storage systems is employed to Shifting part ofapplications’ tasks to IoT devices reduces the transferred data amount chapter proposes a blockchain-based storage system, named Sapphire, for data ana- smart contracts that facilitate and enforce the negotiation ofa contract in the IoT. This contract (OSC) approach employed in Sapphire as a transaction protocol, where IoT objects with IDs, attributes, policies, and methods. We present an OSD-based smart lytics applications in the Internet of Things. All the IoT data from the devices forms returned to clients instead of data files read by them. Therefore, the Sapphire system processors execute application-specific operations. By doing so, only the results are devices interact with such blockchains. For data analytics applications, the IoT device can greatly decrease the overhead of data analytics in the Internet of Things.
