“…Examples of these include Know Your Customer (KYC) checks (Biryukov et al, 2018;Pauwels, 2021), safe ridesharing (Li et al, 2020), and car-sharing (Gudymenko et al, 2020). More importantly, it has allowed for more general and flexible credential and identity management systems (Sonnino et al, 2020;Mukta et al, 2022;Luong and Park, 2023;Namazi et al, 2022;Lee et al, 2021;Rosenberg et al, 2022).…”

We present a general purpose, privacy-preserving framework for verifying user attributes. The framework is designed for users (e.g., a job candidate) to allow a challenger (e.g., a prospective employer) to verify whether the user meets a particular requirement (e.g., does the candidate hold a valid driving license?), without leaking any other information about the user. Importantly, the user is an active part of the challenge-verification process, which ensures that challenges cannot be made without the user's full knowledge and participation. The framework is decentralized and requires a public blockchain. A smart contract is used to manage the challenge-verification process, and zero-knowledge proofs are used to verify challenges in a privacy-preserving manner. We implement a simplified version of the framework using smart contracts deployed on the Ethereum blockchain, and we simulate some simple use cases. All simulation code is available open-source (https://github.com/lifeisbeer/BlockVerify).

“…zkFaith (Namazi et al, 2022) is a protocol where users have their documents verified by an authority and create commitments of their attributes, which are signed by an issuer. The issuer in this protocol also maintains a list of all revoked credentials.…”
