It can integrate cloud computing technology and big data to form a distributed cloud computing system, providing efficient services for local enterprises and governments. In addition, local cloud computing is also widely used, and there are many big data in these applications. Blockchain and local cloud computing technology offers safe and reliable information exchange for data exchange and provides a practical method for analyzing big data. This article aims to study how to analyze and research the application analysis method of big data based on blockchain technology and improve the classical apriori algorithm (CAA). This article compares and analyzes the performance of CAA and improved apriori algorithm (IAA) in big data applications. When the number of key words in the query are 20 and 100, the result search time of the CAA are 1.08 and 9.24\u2009s, respectively, and the IAA are 0.76 and 7.58\u2009s, respectively. The result search cost of the CAA is 12.43 and 91.55\u2009kB, respectively, and the IAA is 5.05 and 63.72\u2009kB, respectively. It is not difficult to see that applying the IAA to the blockchain-based government data-sharing scheme had relatively excellent performance and was worth further promotion and application.<\/jats:p>","DOI":"10.1515\/comp-2023-0281","type":"journal-article","created":{"date-parts":[[2023,10,4]],"date-time":"2023-10-04T12:31:16Z","timestamp":1696422676000},"source":"Crossref","is-referenced-by-count":0,"title":["Blockchain localization cloud computing big data application evaluation method"],"prefix":"10.1515","volume":"13","author":[{"given":"Lin","family":"Xu","sequence":"first","affiliation":[{"name":"School of Teacher Education, Shangqiu Normal University , Shangqiu 476000 , Henan , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2023,10,4]]},"reference":[{"key":"2023100412310718419_j_comp-2023-0281_ref_001","doi-asserted-by":"crossref","unstructured":"A.
