PROFILE
Paul Bastian
Paul Bastian contributed to the openid/OpenID4VCI repository, focusing on enhancing credential issuance workflows and security protocols. Over five months, he streamlined API design by reducing surface complexity, clarified metadata handling, and introduced new proof types such as key attestations to strengthen verifiability. Paul implemented JWT-based wallet attestation for mobile clients, improved nonce handling for secure token presentation, and enabled signed issuer metadata to increase trust. His work emphasized clear documentation and specification writing, using JSON and Markdown to ensure reproducibility and integration clarity. The depth of his contributions addressed both technical consistency and developer experience across OpenID Connect flows.

Jul 1, 2025July 2025 — OpenID4VCI: Key feature delivered and aligned with business goals. Implemented OpenID Verifiable Credential Issuance Metadata Clarification, clarifying that all issuer metadata parameters must be included as top-level claims within the JWS payload. This reduces ambiguity for wallets and issuers and improves interoperability in the issuance workflow. Commit reference: 36cc3d9dc1c16830850233fdafe205c51aae4f4a ("clarification on signed metadata that parameters are included as top-level claims in JWS payload (#565)"). Overall impact: enhanced spec clarity, smoother integration for downstream clients, and stronger consistency across implementations. No major bug fixes documented for this period. Technologies/skills demonstrated: OpenID Connect / Verifiable Credentials, JWS payload structure, requirement clarifications, and robust change-tracking via commit history.

Dec 1, 2024December 2024: Delivered Wallet Attestation as a JWT-based client authentication method for native mobile wallets in the openid/OpenID4VCI repository. Implemented a platform-agnostic attestation format enabling direct interaction between the wallet and the credential issuer, clarifying the wallet attestation's role in secure credential issuance. The work strengthens onboarding security, reduces issuance friction for mobile wallets, and establishes groundwork for broader cross-platform adoption.

Nov 1, 2024November 2024: OpenID4VCI delivered two principal outcomes: API surface reduction and strengthened credential issuance security. The team removed the optional 'claims' parameter from Credential Request across ISO mdoc and SD-JWT VC formats to resolve cross-format inconsistencies in line with Hybrid WG guidance, and introduced key attestations as a new proof type to enhance verifiability. These changes improve developer experience, reduce surface area for integrators, and strengthen trust in issued credentials.
