I published a production implementation of OpenAC as an npm package.
@l8zk/sdk generates and verifies Spartan2 zero-knowledge proofs with performance matching the paper:
• ~96ms show proof
• ~34ms verification
• full reblinding for unlinkability
• transparent setup (no trusted ceremony)
Current scope: pre-compiled circuits with fixed payload size, matching official PSE benchmarks. Dynamic credential support is under active development.
Built on top of the MIT-licensed zkID work by the PSE / Ethereum Foundation team.

It describes a zero-knowledge identity construction designed to work with existing identity stacks and was purposely constructed to be compatible with the European Digital Identity Architecture and Reference Framework (EUDI ARF). github.com/privacy-ethere…
