Abstract

A data writing method, a data writing device and a storage medium based on a block chain intelligent contract are used for protecting privacy information of a block chain account. The method comprises the following steps: encrypting the information to be encrypted of the first block chain account according to a pre-obtained symmetric key to obtain an information ciphertext of the first block chain account; encrypting the symmetric secret key according to the public key of the first block chain account to obtain a secret key ciphertext of the first block chain account; and writing the information ciphertext of the first block chain account and the key ciphertext of the first block chain account into a block chain where the first block chain account is located through an intelligent contract.
