# Special Equipment Safety Supervision System Architecture Based on Blockchain Technology
## 6 Conclusions  
The number of special equipment in China is increasing year by year, and the related safety supervision work is becoming heavier and heavier. In the context of China's social relations, represented by the reciprocal social network, the traditional safety supervision system of special equipment has exposed many drawbacks, resulting in endless loopholes in safety supervision. Considering the high frequency of safety accidents in special equipment, and the huge casualties and property losses caused by it, it is necessary to improve the safety supervision system. Aiming to find out the specific requirements for improving the safety supervision system, we conducted a requirement analysis based on the current supervision situation and the suggestions in numerous literature and accident reports. As a result, the current specific requirements can be summarized into four parts: efficient accident responsibility tracing, more transparency, more efficient data sharing, and integrating more functions.  
For a long time, many researchers have failed to put forward feasible solutions to meet these requirements, so that the situation of safety supervision could not be changed, but blockchain technology provides different possibilities. Many unique features of blockchain technology, such as the inherent transparency mechanism and data-sharing mechanism, just meet our requirements. Therefore, we propose to design a special equipment safety supervision system based on blockchain technology. As described in this paper, our basic idea is to build the system on a distributed digital ledger with unlimited extension, and treat \"transactions\" of the blockchain as information updates, so we can record all supervision information by updating the ledger. In order to adapt to the technicalfeatures of special equipment safety supervision work and simplify the development process of the system, the Hyperledger Fabric blockchain platform will be adopted. From the system architecture and the description of system functions, we can see that the system can maintain an efficient and safe implementation mechanism, and various supervision work can be well completed in it.  
Although the system has so many advantages and excellent feasibility, some data standardization and operation process optimization design still need to be improved. The development and testing of the system are a long process. In the future, we will cooperate with more supervision authorities and blockchain developers to apply the system to practice as soon as possible. In addition, we will also try to apply the design ideas of the system to other fields that also require safety supervision; the mining industry is the most likely target.
