ETH Belgrade 2024: ZKPs on Mina, zkPassport and SoulBound NFTs

This article presents ZK proofs on the Mina blockchain, zkPassport and soulbound tokens as a path toward decentralized identity, sybil-resistant governance and off-chain data for Web3. It argues that Web3 lacks foundational identity components, which leaves users dependent on centralized platforms and custodial wallets. It states that Mina's fixed size of 22 KB sets it apart from traditional blockchains, which can be hundreds of gigabytes. It cites the zkPassport Core Grant proposal, which considers using passport data in Mina wallets, and notes that KYC could be used if zero-knowledge passport validation is not viable. It also describes ZKON's zkOracle partnership with the Mina Foundation.
