An interactive briefing tool that makes the case for Verifiable Credentials — built for CDPI.
VC Articulator is a single-page web application designed to help government decision-makers, technologists, and policy advisors understand why Verifiable Credentials (VCs) matter and how to implement them. It combines live demos, economic modelling, and technical guidance into three focused pages.
Upload any identity document and the app instantly demonstrates how easily it can be forged using AI-based image manipulation. It then shows a difficulty-to-forge analysis, a step-by-step attacker playbook, and explains how cryptographically signed VCs eliminate the forgery risk entirely.
An interactive cost calculator for KYC / Financial Services that compares traditional manual verification ($4–8 per check) against VC-based verification (near $0). Includes:
- A population slider to model costs at national scale
- Scenario toggles (Conservative / Base / Optimistic)
- Unit economics broken down by actor: Infrastructure Holder, Issuer (Government), and Acceptor (Bank/Institution)
- Citizen time burden comparison (hours lost to manual processes vs. instant digital verification)
- Sector extrapolation for healthcare, education, and more
Sector-specific implementation guidance covering 11 sectors (National ID, Education, Healthcare, Driver's Licence, and more). For each sector it shows:
- Credentialing priorities — Privacy, Interoperability, Adoption, Offline Use
- Primary standards — EBSI / eIDAS 2.0, mDL ISO 18013-5, OID4VC, W3C VC, AnonCreds (ZKP), SD-JWT VC
- Complementary standards — additional standards relevant to the sector
- Links to the CDPI Vision Paper and the VC Use-Cases deep-dive site
- Pure HTML / CSS / JavaScript — single
