Abstract
The Internet of Things is widely used and has far-reaching significance. It is essential to ensure the trustworthiness of the IoT computing environment. Using blockchain technology to store and manage the data traces in the IoT is feasible to implement the trustworthy IoT. In a “Cloud-Edge-End” structure, the difference in the degree of energy constraint between various parts makes the use of the same consensus algorithm a compromise between overall performance degradation and energy constraints on terminal devices. We take advantage of the high modularity of the chained consensus algorithm to build a layered consensus mechanism framework, running a two-phase consensus algorithm in the local environment of the terminal devices, and a three-phase consensus algorithm with better overall performance. Preliminary evaluation shows that this scheme is feasible.
