摘要
The quality traceability of precast components has largely affected the widespread adoption of prefabricated buildings.Blockchain technology provides an effective solution to change the centralized storage mode of traditional traceability system and its related disadvantages.In this paper,we propose a framework of quality traceability system for precast components based on blockchain technology.The system framework adopts a hybrid blockchain architecture and dual storage mode,defines three types of smart contracts,and creates an interactive and efficient source tracing query method,which could effectively achieve the goals of decentralization,openness,and non-tamperability,as well as efficient traceability.
