DVCC - Decentralized Identity and Verifiable Co-creation Consortium

The DID/VC Co-Creation Consortium (DVCC) is a Japanese industry consortium established in October 2023 to promote the adoption and interoperability of Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) in Japan. Founded by major Japanese corporations including Mitsubishi UFJ Trust Bank, NTT Data, Hitachi, and Fujitsu, the consortium focuses on developing business use cases and technical standards for Self-Sovereign Identity implementation.

The consortium operates through multiple working groups focused on key areas: business co-creation, interoperability rule development, and resource sharing. It implements technical standards from organizations like W3C, IETF, and OpenID Foundation while adapting them specifically for Japanese business environments. A notable development is the establishment of the Personal Verification Subcommittee in 2024, which explores using DIDs and VCs for Know Your Customer (KYC) processes in financial institutions.

Key technical features and initiatives include:

• Implementation of W3C DID specifications
• Development of interoperability rules for DID/VC systems
• Creation of shared infrastructure for credential verification
• Integration with existing digital identity systems

  Notable implementations include a pilot project for personal verification in banking services, involving major financial institutions like Mitsubishi UFJ Financial Group and Sumitomo Mitsui Financial Group
