ACCOUNT ATTRIBUTE PROCESSING METHOD BASED ON BLOCKCHAIN, AND DEVICE AND STORAGE MEDIUM

摘要

Provided are an account attribute processing method based on a blockchain, and a device and a storage medium. The method comprises: receiving a transaction request of a user account sent by a terminal; determining whether the transaction request conforms to a security rule corresponding to a security attribute of the user account; and if it is determined that the transaction request does not conform to the security rule corresponding to the security attribute, sending a security prompt notification to the terminal according to the security rule and the transaction request. In the present application, a security attribute and a security rule corresponding thereto are set in a blockchain account, thereby improving the account security. The risk of an account balance being completely transferred can be reduced by means of a single limit and a daily limit. Before account transfer, a user confirms the identity of the other party, and a loss caused by transfer to a wrong object is prevented. A user is notified when a relatively high amount is transferred, thereby improving the security of an account. An account is frozen when a private key is stolen, the loss of an account balance is prevented, and the account balance of the stolen account is completely transferred to a standby account, thereby improving the property security of a user.
