deLinZK is a Zero-Knowledge solution providing a platform for organizations and employees to accurately issue Verifiable Credentials which serve as Proof-of-Employment. It provides a comprehensive job board allowing organizations to post jobs, and employees to apply to them. The organizations do not need to spend additional time verifying the work experience of applicants, since all of them are already verified by deLinZK through a ZKP way. Built at ETHforAll hackathon, this project addresses the problem of fake credentials and forged certificates in networking platforms by using Polygon ID for credential verification.
