Blockchain-based Microbial Sequencing Gene Sharing System: Design And Implementation

After the wave of Bitcoin,blockchain began to blossom in various industries.After extensive research and research on the development of blockchain technology,microbial gene data sharing and storage,the research found that compared with the closed technology of foreign gene sequencing service platform,the common problems of gene sequencing platform at home and abroad: the demand for microbial sequencing services in university laboratories and individuals has not been solved;The unique decentricization,data encryption security,non-tamperable and other characteristics of blockchain provide ideas for solving the above problems,so the paper puts forward a microbial sequencing gene sharing platform based on blockchain,the main research content is as follows:The system combines blockchain,smart contract,IPFS and distributed microservices Web development technology to realize the microbial sequencing gene sharing platform based on blockchain,which facilitates researchers and reduces the cost of researcher management.For the storage of microbial gene data,the traditional single-point central management is abandoned,the distributed gene file management network is designed by IFPS(interstellar file system),the hidden danger of single point of failure is reduced,and multi-node service is provided to ensure the stability of file service.based on blockchain design and implementation of gene sharing integration trading model,microbial gene data as an asset in the user chain,about gene data sharing,purchase,provide permissions,by intelligent contracts for automatic execution,platform personnel can not intervene,to achieve a credible,protect user privacy of genetic data transactions.The paper finally designs and implements the microbial gene sequencing sharing platform based on blockchain,introduces blockchain technology,takes the user’s microbial sample gene data as the asset on the chain,adopts the integral trading model incentive mechanism to manage the gene sharing community,uses the smart contract to write the logic of the business layer,automatically executes and can’t tamper with,guarantees the authenticity of the microbial gene data,and also reduces the trust cost of the integration transaction.
