Block data processing method and device and electronic equipment

The invention discloses a block data processing method and device and electronic equipment, and the method comprises the steps: adding a first verification data segment and a block length field into each piece of block data in a first original file for storing the block data, and obtaining a block file; adding a second verification data segment and an index length field into each piece of block index information in the second original file to obtain an index file; in response to a file processing request for the block files, performing corresponding processing on each block file according to the first verification data segment, the block length field and the block data to obtain a file processing result; and according to a file processing result, updating each index file in combination with the second verification data segment, the index length field and the index data. The block data processing efficiency can be improved, the security risk in the data processing process can be reduced, and the method can be
