The model uses an Issuer-Holder-Verifier trust triangle: authorities sign credentials, users hold them in wallets, and applications request specific proofs, with selective disclosure limiting exposed data. The standards stack combines SD-JWT VC or mdoc credential formats, OpenID4VCI for issuance, OpenID4VP for presentation, and the W3C Digital Credentials API for browser-wallet invocation. Production verification also requires issuer trust lists, trust-framework integration, and key rotation, not merely signature checks.

## Summary

Verifiable Digital Credentials (VDCs) are presented as a new trust layer for applications that need to verify claims such as age, licenses, employment, or eligibility without collecting documents and excess PII. The model uses an Issuer-Holder-Verifier trust triangle: authorities sign credentials, users hold them in wallets, and applications request specific proofs, with selective disclosure limiting exposed data. The standards stack combines SD-JWT VC or mdoc credential formats, OpenID4VCI for issuance, OpenID4VP for presentation, and the W3C Digital Credentials API for browser-wallet invocation. Production verification also requires issuer trust lists, trust-framework integration, and key rotation, not merely signature checks. Because browser API rollout is still progressing, the recommended baseline is redirect-based OpenID4VP with the Digital Credentials API added as a progressive enhancement, starting with one bounded verification use case.

## Context

Applications have traditionally relied on document uploads, third-party verification APIs, and centralized PII storage to verify claims. That approach creates data-protection obligations, compliance costs, manual review queues, and dependence on vendors holding users’ identity data. The source identifies a gap between deployed issuer and wallet infrastructure and slower verifier-side adoption.

## Approach / What changed

Use the Issuer-Holder-Verifier model with cryptographically signed credentials, wallet-held proofs, and selective disclosure. Choose SD-JWT VC or mdoc according to the use case, use OpenID4VCI for issuance and OpenID4VP for presentation, integrate issuer trust lists and trust frameworks, and use redirect-based OpenID4VP as the baseline while adding the Digital Credentials API where supported.

## Takeaways

- A valid credential signature is insufficient: a verifier must also accept the issuer through a curated trust list and integrate the relevant trust framework, including key rotation where required.
- SD-JWT VC suits web and backend use cases such as age, employment, and license verification, while mdoc is intended for mobile driver’s licenses and government-issued digital IDs.
- The source recommends starting with redirect-based OpenID4VP for broad compatibility, then adding the W3C Digital Credentials API as a progressive browser experience enhancement.
