Abstract
Systems and methods for implementing a multidimensional identity protocol (MDIP) are disclosed. The techniques described herein can include establishing an MDIP method of a decentralized identifier (DID) specification. The MDIP DID method can be used to provide a peer-to-peer identity layer with secure decentralized verifiable credentials. The MDIP can be used to create a DID anchored to a CAS. The DID can include at least a portion of a unique identifier provided by the CAS and derived from an MDIP DID create operation for a document. The MDIP can be used to register the DID on a decentralized registry. The registered DID can identify a pointer to the document in the CAS. Registered DIDs can be resolved via the MDIP to obtain the associated DID document.
