Abstract

Abstract: With the continuous development of the Internet of Things (IoT), the application of blockchain technology to the Internet of Things has become a trend of the times. As we all know, the core of the blockchain lies in the consensus mechanism. In order to apply the blockchain to the Internet of Things, and for subsequent research needs, this research proposes a lightweight, high-throughput consensus mechanism system. Using scalable technology, any number of nodes and gateways can be set up. The experimental results show that the system throughput increases synchronously with the increase of the test load; in addition, when the test load is 800tps, the system throughput reaches the maximum value, which is close to 600tps. When the test load exceeds 800tps, the actual system throughput begins to drop, and about 90% of transactions have a delay time of 5000ms. This blockchain consensus system can be used for the simulation of lightweight IoT systems.
