Protocols and Standards
The success of SSI relies on interoperable protocols and standards. Key contributions include:
W3C DID Standard: Defines how to create and manage globally unique, user-controlled identifiers independent of any centralized authority. This empowers users to control their DIDs and where their identity data resides.
W3C Verifiable Credentials Data Model: Specifies the structure and format for Verifiable Credentials (VCs), detailing the information a VC can contain, its formatting, and cryptographic signing for tamper-proof verification. This standardization ensures consistency across the SSI ecosystem.
Industry Initiatives and Working Groups: Organizations like the Decentralized Identity Foundation work on developing and implementing best practices for SSI. These groups bring together stakeholders to foster interoperability, promote innovation, and ensure a robust and user-centric SSI ecosystem.
Standards compatibility is the key to data interoperability. Empeiria enables data sharing across various data ecosystems and organizational adoption by adhering to industry standards in the table below.
