Abstract
The concept of smart city refers to the improvement of the quality of life of the city by making full use of idle resources by sharing. However, limited by the technical level, the current resource sharing system mostly adopts centralized data storage mode. Systems managed in this way are vulnerable to multiple threats. The tested blockchain technology with the characteristics of decentralization and tamper resistance can effectively prevent various risks. Starting with the architecture of blockchain intelligent contract, this paper puts forward a structural optimization factor model of intelligent contract. To optimize the structure of blockchain intelligent contract, the gas optimization theory is put forward by changing the order, reducing the use of costly EVM data fields, reducing redundant fields, and optimizing intelligent contract codes. Experimental analysis of the proposed model is carried out, and the effectiveness of the proposed method is verified by comparing the transaction execution time of cost calculation with the cost of executing gas, which can provide reference for the selection of intelligent contract organization structure of smart city resource sharing system.
