摘要:

为集中整合优质作物种质资源,降低中心化数据存储压力,保障优质作物种质数据安全性,加大优质作物种质资源保护与利用力度,针对当前鲜有研究优质作物种质资源数据存储问题的现状,构建“区块链+IPFS”的链上链下协同存储模型。通过降低链上存储压力,搭建IPFS(星际文件系统)节点,将具体种质数据存储在IPFS中,将IPFS返回的Hash值以及种质摘要信息存入区块链,解决区块链无法承担冗余数据量的问题,设计了作物发布、添加和查询的智能合约,并调用智能合约完成对数据的操作。从存储空间、存储时间两方面对模型进行了存储性能测试。实验表明该模型降低了本地存储空间的存储压力;存储时间虽略有延迟,但在可接受范围内。

Abstract:

In order to centralize and integrate high-quality crop germplasm resources, reduce the pressure of centralized data storage, improve the security of high-quality crop germplasm data, and increase the protection and utilization of high-quality crop germplasm resources, a "blockchain+IPFS" on chain and off chain collaborative storage model was constructed in response to the current situation where there is little research on the storage of high-quality crop germplasm resources data. Reduced on chain storage pressure, built IPFS (InterPlanetary File System) nodes. The specific germplasm data was stored in IPFS, Store the hash value and germplasm summary information returned by IPFS into the blockchain to solve the problem of the blockchain being unable to bear the amount of redundant data. designed a smart contract for crop publishing, adding, and querying, and called the smart contract to complete data operations. Finally, the storage performance of the model was tested in terms of storage space and storage time. Experimental results indicate that the model reduces the storage pressure on local storage space; although there is a slight delay in storage time, it remains within an acceptable range.
