Abstract

The invention provides a verifiable statement generation method and device, electronic equipment and a storage medium, and relates to the technical field of block chains. The method can comprise the following steps: a verifiable declaration application request of a user is received by a issuer block chain, wherein the verifiable declaration application request is used for requesting to generate a verifiable declaration for the user; the issuer block chain analyzes the verifiable declaration application request to obtain attribute information of the user, and writes the attribute information into a local oracle machine contract; the oracle machine service obtains a verification intermediate result of the user according to the attribute information written by the local oracle machine contract, and the verification intermediate result comprises verification result declaration data; the issuer block chain obtains a verification intermediate result of the user from the oracle machine service; and the issuer block chain generates a verifiable statement of the user according to the verification intermediate result of the user. According to the scheme, full supervision of the application process can be realized, and the possibility of data tampering is avoided, so that the reliability of the generated verifiable declaration is improved.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular, to a verifiable statement generation method, device, electronic equipment and storage medium. Background technique [0002] Digital identity information, such as DID (English full name: Decentralized Identifiers, Chinese full name: Distributed Identity Identification), is a decentralized verifiable digital identifier. DID can identify the identity of the individual, the identity of the organization, etc., but since there is no real information about the individual or organization in the DID, such as name, home address, etc., users usually associate the DID with the verifiable statement (English full name: Verifiable Credential, VC for short), through a verifiable statement to prove information such as age, education, and certain permissions. How to generate effective and trustworthy verifiable claims has become the focus of research. [0003] In the existing technol...
