However, big data still form \u201cdata islands,\u201d which seriously affects the level of scientific research and the progress of scientific research. In this regard, this article proposes the research and realization of the big data scientific research model and key mechanism based on blockchain. This article uses the <jats:italic>K<\/jats:italic>-means algorithm to cluster scientific research data and reasonably utilizes the decentralization, smart contracts, and non-tampering characteristics of the blockchain to design a distributed data model based on the blockchain. This article proposes that a BIZi network is formed based on a blockchain Interplanetary File System (IPFS) and Zigzag code (blockchain, IPF Sand Zigzag code, BIZi for short) to achieve reliable data connection and through a set of data access control mechanisms and data service customization mechanism to effectively provide data requirements for scientific research. Finally, IPFS network transmission speed performance can better meet the needs of scientific research. The larger the number of file blocks, the higher the fault tolerance rate of the scheme and the better the storage efficiency. In a completely open data-sharing scenario, the fault tolerance rate of Byzantine nodes is extremely high to ensure the stability of the blockchain. The current optimal consensus algorithm fault tolerance rate reaches 49%.<\/jats:p>","DOI":"10.1515\/comp-2022-0258","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T09:17:47Z","timestamp":1666862267000},"page":"357-363","source":"Crossref","is-referenced-by-count":0,"title":["A study on the big data scientific research model and the key mechanism based on blockchain"],"prefix":"10.1515","volume":"12","author":[{"given":"Shengwei","family":"Wen","sequence":"first","affiliation":[{"name":"Department of Science and Computer, Ganzhou Teachers College , Ganzhou , 341000, Jiangxi , China"}]}],"member":"374","published-online":{"date-parts":[[2022,10,27]]},"reference":[{"key":"2022102709173576888_j_comp-2022-0258_ref_001","doi-asserted-by":"crossref","unstructured":"A.
