| Agricultural natural resources are the basic resources of modern agricultural production,generally referring to various elements,such as meteorology,water,land,biological and other natural objects.A large amount of information and many links are involved in traditional agricultural natural resource platform,and each production factor is independent of each other,so the information is not circulated and resource utilization rate is not efficient.In addition,traditional agricultural natural resource platforms mostly adopt centralized management and control,so data is easy to be leaked,lacking of security and reliability.This paper studies the construction of agricultural natural resources platform by taking advantage of the decentralized,tamper-free and traceable characteristics of blockchain technology.The main contents are as follows:(1)Study the agricultural natural resources storage model combining block chain and IPFS.In this model,meteorology,land,water,biological and other data of agricultural natural resources are not directly stored in the blockchain network,but the original data is stored in combination with the IPFS system,and the HASH generated by IPFS is uploaded to the blockchain network to ensure the integrity and security of agricultural natural resources data and reduces the storage pressure on the chain.(2)Design the overall architecture of agricultural natural resources platform based on block chain technology.This paper analyzes the feasibility of the platform based on blockchain technology and establishes the overall framework.Then,according to the overall framework,the main functional modules of the agricultural natural resources platform based on block chain are designed as follows: user management,collection and transmission,storage,processing and display modules;Finally,ethereum technology is used to design the life cycle model and security model of the platform.(3)Develop and implement an agricultural natural resources platform based on blockchain technology.In view of the ethereum development environment,HTML,CSS and JAVA SCRIPT is choosed to realize the user front page,GO language is used to program logical code,and data in the form of HASH is stored on the blockchain in this paper.(4)Propose specific application of agricultural natural resources platform based on block chain.Taking farmland protection as an example,the function of data reporting can be added to the platform in combination with blockchain technology.Users can report the data,at the same time,the data link and smart contract writing can be displayed to complete the traceability query function of farmland protection.In this paper,the platform of agricultural natural resource is established based on blockchain,and the chain agricultural natural resources information of all elements is realized on the platform,so that the authenticity and traceability of data is enhanced,with the help of the platform,basic information support for agricultural natural resources can be achieved,such as asset ownership confirmation,asset ownership confirmation,agricultural insurance and other business needs.Finally,the digitization and the value of agricultural natural resources are implemented. |
