摘要/Abstract

摘要：

农作物种质资源是国家的战略性资源,是保障国家粮食安全、发展现代种业的物质基础。农作物种质资源工作经过七十多年的发展,已经形成了考察收集、评价鉴定、编目入库、共享利用的系统性工作流程。在计算机技术快速发展的当下,利用信息技术促进农作物种质资源工作规范化是种质资源工作的发展趋势。我国种质资源工作信息化经过三十多年的发展,已经建立了完善的种质资源数据库以及信息系统。针对目前种质资源工作中出现的种质数据溯源困难、难以安全传输以及育成品种产权纠纷等问题,本文提出了一种基于区块链的解决方案,研究了基于区块链的种质资源数据管理方案、存储方案、共识方案和加密方案,将区块链技术体系中的关键技术应用到农作物种质资源数据管理当中,提出了一种区块链技术在种质资源数据管理领域的应用设想。结合目前种质资源工作和区块链技术的发展现状,总结了区块链技术在种质资源数据管理领域的发展方向。

Abstract:

Crop germplasm resources are the strategic resources of our country and the fundamental material for safeguarding national food security and developing modern seed industry.The past 70 years have witnessed China have formed a systematic work of crop germplasm resources,including investigation and collection, evaluation and identification, cataloging and storage, and sharing and utilization. With the rapid development of computer technology, using information technology to promote the standardization of crop germplasm resources’ work is the prospective trend of germplasm resources work. The past 30 years have witnessed China has established a complete database of germplasm resources and information systems for germplasm resources’ work.For the difficulty in traceability of germplasm data, transmission, and property rights disputes in the current germplasm resources, this paper proposes a blockchain-based solution and studies the germplasm resources data Management plan, storage plan, consensus plan and encryption plan based on blockchain . Combined with the current development of germplasm resources’ work and blockchain technology, this paper analysis the prospects of blockchain technology using in the field of germplasm resources.

Key words: germplasm resources, blockchain technology, data management, encryption algorithm, blockchain, asymmetric encryption, crop, germplasm repository
