Abstract
As an underlying support technology, blockchain is a shared ledger system and a computational paradigm, which is decentralized, and it is highly compatible with the distributed economic system. The distributed scheduling model of agricultural business resources based on the public service platform is a comprehensive solution to the current situation of agricultural industry which is ”scattered, small, disorderly and weak”, and plays an important role in integrating decentralized resource and making on-demand scheduling. Aiming at some key problems in the current Chinese public service platform, this paper proposes a public blockchain of agricultural supply chain system based on double chain architecture, mainly studying the dual chain structure and its storage mode, resource rent-seeking and matching mechanism and consensus algorithm. The results show that the chain of agricultural supply chain based on double chain structure can take into account the openness and security of transaction information and the privacy of enterprise information, can self-adaptively complete rent-seeking and matching of resources, and greatly enhance the credibility of the public service platform and the overall efficiency of the system.
Introduction
Agricultural supply chain is a complex system which responsible for the circulation of agricultural products in the market. As the carrier of the circulation of agricultural products, agricultural commercial resources are important guarantee to meet the demand of agricultural products and to maintain their quality and safety. At present, there are more than 230,000 agricultural business enterprises in China, most of which are small and medium-sized enterprises. Agricultural commercial resources could be characterized as dispersion significantly. Driven by interests, agricultural business resources have high coverage rates in developed regions, and the resource investment is obviously surplus. However, the coverage rate in remote and underdeveloped regions is extremely low, and agricultural business enterprises can hardly spontaneously meet the demands for agricultural products in remote and underdeveloped regions, showing extrusive social contradictions. With the rapid development of computer technology and distributed computing, public service platform with the targets of ‘‘centralized management of decentralized resources and decentralized service of centralized resources’’ has become the key to solve the contradiction between the demand and supply of agricultural business resources.
