After finding the first information digest value, the first electronic device may find a second information digest value stored in association with the first information digest value, that is, an information digest value corresponding to the updated file. When the second information abstract value is found, the article is indicated to be updated.
Then, in an implementation manner, the first electronic device may download the update file corresponding to the article according to a storage path recorded in the block chain distributed book and stored in association with the second information digest value, so that automatic update of the file may be implemented.
In another implementation, the first electronic device may also prompt the user B to update the article after finding the second information digest value. Therefore, the user can know that the updated file corresponding to the article exists in time. And when an update instruction sent by the user B is received, the first electronic device may download the update file corresponding to the article according to a storage path recorded in the blockchain distributed book and stored in association with the second information digest value.
