Abstract:

Internet of Things (IoT), an significant support for strategic emerging industries, is re-building industrial systems, such as transportation, healthcare and energy, while a number of new features and requirements like data cross-industry sharding appear in recent years. The emerging Blockchain technology has provided a promising opportunity to break information island and single-domain management in multi-domain IoT systems by leveraging distributed storage. On the other hand, the transaction consensus throughput in the mainstream blockchain systems, such as Ethereum and Fabric, is far from meeting the demand for massive data storage in time in multi-domain IoT systems. In this paper, we design a sharding protocol called MDIoTSP. The protocol first partitions the overall blockchains into many small shards, each of which generally recognized as a micro-blockchain according to the multiple domains, and then make the final consensus by merging the hash digests of the sub-blocks which generated from the shards for the multi-domain IoT blockchains ecosystem specifically. We also develop MicrothingsChains to run MDIoTSP in multi-domain IoT blockchains to prove our assumption that MDIoTSP scales up the transaction consensus throughput near linearly with the number of shards.
