Enhancing the engineering supervision process in China : a solution enabled by integrating hybrid blockchain system

This paper analyzes the current status of the engineering supervision process in construction and infrastructure projects in China. It discusses the existing problems, such as low efficiency of supervision, distorted monitoring data, resource waste, and environmental damage. Based on extensive literature research and combining the consensus mechanism, ECDSA encryption algorithm and so on, the paper proposes the idea of integrating blockchain technology with the engineering supervision process. This includes the decision of blockchain type, the use of digital signature technology to implement responsibility, and the construction of a hybrid blockchain system using the blockchain's consensus mechanism. The paper presents the general design, the design of the system structures, and the design of modules of the system. Through this system, project participants can verify their identities and share sensitive information confidentially, thereby improving the efficiency of supervision work and preventing data forgery, reducing resource waste, decreasing carbon emissions, and minimizing environmental damage.
