Abstract
With the continuous progress of blockchain technology, how to use it for commodity traceability has become a concern. This study mainly discusses the Internet of Things supervision system and supply chain financial supervision method based on blockchain technology. The whole blockchain network is a decentralized system, which consists of six layers: data layer, network layer, and consensus layer. These three layers are the foundation layer; the other three layers are incentive layer, contract layer, and application layer. The interface of the platform needs to be conceived in combination with the business of building materials. According to the functional differentiation, the required interfaces mainly include information generation interface, information verification, information retrieval, and other information interfaces. Smart contracts can process data, operate asset transactions, manage smart assets, and expand the ability of blockchain to use data. In this way, the blockchain technology can trace the source of the data, so as to ensure the authenticity and security of the data. Blockchain technology can be used in data tracking. Specifically, in the building materials industry, with the help of blockchain technology, building material mixing enterprises can see the raw materials such as sand and gravel purchased under the order, the region where they are produced, the time point of transportation, the carrier, etc. In the process of supply chain financial supervision experiment, when the pledge rate of building materials is within the range of [0.4206,1], the bank income under the block chain mode is higher. The system designed in this study realizes the certification and traceability of building materials and has good use value.

Summary
With the development of Internet of Things and intelligent manufacturing, the variety and quantity of consumer products are increasing, and people’s dependence on consumer products is deepening. They believe that blockchain (BC) is a disruptive technology, and many applications from cryptocurrency to smart contracts have been discovered, which are potential solutions to these challenges They proposed a BC-based architecture to protect the privacy of users and improve the security of the vehicle ecosystem. The innovations of this article are mainly reflected in the following: (1) a detailed introduction to the blockchain technology and the Internet of Things building material supervision platform; (2) conducted an experimental analysis on the traceability of the blockchain and, at the same time, explored the impact of order volume fluctuations on bank financing decisions and conducted system performance testing and analysis
