説明
We built an application that uses zk proofs to allow users to link and privately prove their multi-platform digital credentials (like their age, affiliations, academic qualifications, professional memberships). This is intended to complement the work being doing in the EU with the EU Digital Identity Wallet rollout which is happening at the end of 2025.
We believe that the intersection of verifiable credentials and zk proofs remains largely untapped and a large scale adoption could enable organisations to have data driven insights like never seen before.
Today, it's hard for organisations to get deeper insights about their consumer/user demographic without asking users to upload their personal data. We know that more personal data = more data breaches so we want to avoid this (not to mention that consumers dont want to disclose their personal data!).
Our app, the PaaS ("proof as a service") helps users prove their credentials without oversharing their personal data, unlocking value for organisations who can access verified insights, without the risk.
Our app lets users link their digital credentials (stored in web2 or web3 wallets) and store identifiers pointing to those without the underlying data. They can then choose to generate zero knowledge proofs from those underlying credentials and share the proofs with third parties in a way that doesn’t overshare their personal data.
ハッカソンの進行状況
We built an application comprising: 1. web3 user authorisation & authentication using Argent wallet; and 2. a proof scheme (we implemented logical verification of the user’s name and age and generated a proof using a zk SNARK prover). We developed our dapp with snarkjs, Starknetjs, React, enabling wallet authentication via Argent wallet and the paas backend. The application generates and verifies the proof on the client side, with the user selecting the underlying data from which the proof is to be generated. We also implemented the basic SDK of the application on Open ID Connect, which allows authorisation in third party applications.

資金調達の状況
We are partnering with Fraunhofer Institute for a pilot with their TRAIN trust architecture and will jointly apply as a consortium for EU grants.
