Data analysis method and device based on block chain, electronic equipment and storage medium

The invention discloses a data analysis method and device based on a block chain, electronic equipment and a storage medium. The method comprises the steps of obtaining to-be-processed data related to data storage; the to-be-processed data is divided into multiple pieces of sub-data, data information is extracted from each piece of sub-data, and the data information is data needed for data analysis in different data analysis scenes; constructing a data element corresponding to each piece of sub-data based on the data information to obtain a plurality of data elements corresponding to the to-be-processed data; and uploading the plurality of data elements to the block chain so as to perform data analysis processing on the plurality of data elements on the block chain. The diversity of the data on the chain is realized, and the accuracy of data analysis and data mining is improved. 本申请公开了一种基于区块链的数据分析方法、装置、电子设备和存储介质。该方法包括：获取与数据存储相关的待处理数据；将待处理数据划分为多个子数据，并从每个子数据中提取数据信息，其中，数据信息为在不同数据分析场景下进行数据分析所需的数据；基于数据信息构建每个子数据所对应
