Abstract

The invention relates to an account information confirmation and retrieval method and device based on a block chain, an electronic device and a storage medium. The method comprises the steps of afteran account information confirmation request sent by a user is received, analyzing and acquiring the user identity information in the account information confirmation request; calculating an md5 valuecorresponding to the user identity information through an intelligent contract based on the block chain, and comparing the md5 value with an md5 value corresponding to the user identity searched in apreset user identity information and md5 value corresponding table in the intelligent contract; and if the comparison results are consistent, sending an account information verification request to theuser through the smart contract based on the block chain, receiving a verification result returned by the user, completing account information confirmation, further binding a new address again through the smart contract, and updating the contract related data to complete the account information retrieval. According to the invention, the security level of the user account information is improved based on the block chain technology.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, electronic device, and computer-readable storage medium for confirming and retrieving account information based on blockchain. Background technique [0002] With the continuous development of blockchain technology, the scale and maturity of the application in the blockchain field have been greatly developed. Decentralization is a well-known feature of blockchain. The decentralization of the blockchain enables each member to have the right to control their own assets (data, rights and funds, etc.), and the private key is the proof of identity. Mastering the private key means mastering all assets under the identity. assets. Due to the decentralization of identities, it means that once the private key is lost, it is no longer possible to retrieve the assets directly belonging to this identity through platform verification like a centralized system. ...
