Zero-Knowledge KYC using MultiversX NFTs

This project represents a Zero-Knowledge design for the usual KYC workflow. Its frontend and backend are hosted using genezio and the smart contract is on MultiversX. The KYC provider that was used is Passbase.

The project has the following workflow:

• reputation giver
  • creates a space (an sft collection)
  • adds campaigns
  • can choose to distribute a campaign via KYC
• reputation collector
  • can go to a space
  • can choose a campaign
  • can verify via KYC
  • can claim NFT once KYC is verified

This makes it so a user can complete a KYC once and receive a special NFT that shows everyone on the blockchain they completed the KYC without giving the other blockchain users access to their data.

You can interact with a deployed demo here.
