A Zero-Knowledge Proof-based NFT is a non-fungible token (NFT) that utilizes zero-knowledge proofs to verify users' eligibility without revealing their private data.
A Zero-Knowledge Proof (ZKP)-based NFT is a non-fungible token (NFT) that utilizes zero-knowledge proofs to verify users' eligibility without revealing their private data. Zero-knowledge proofs allow one party (the prover) to demonstrate knowledge of a value to another party (the verifier) without disclosing the actual information. This enhances security and privacy while ensuring access is restricted to verified individuals.
Privacy-Preserving: Users can verify eligibility without exposing personal data.
Replay Attack Prevention: Each proof is used only once to prevent fraudulent reuse.
Secure Minting: Only verified users can mint NFTs using valid cryptographic proofs.
Identity-Based Access: Ensures NFTs are assigned to pre-verified individuals only.
Efficient and Transparent: Uses smart contract logic to authenticate zero-knowledge proofs on-chain.
Decentralized and Trustless: Eliminates the need for third-party verification.
Network: EduChain
Contract Address: 0x7E502AA4a3d10fE377f09efF7224ceC96Faf62db
Proof Submission: Users generate and submit a zero-knowledge proof.
Validation: The contract verifies the proof against stored valid hashes.
Minting Process: If the proof is valid, an NFT is minted and assigned to the user.
One-Time Use: The proof is invalidated after use, preventing replay attacks.
Ownership Tracking: The contract maintains an ownership record of minted NFTs.
Balance Check: Users can check their NFT holdings using balance queries.
Register a Proof: setValidProof(bytes32 proof) - Admin sets a valid proof.
Mint an NFT: mint(bytes32 proof) - Users provide a valid proof to mint an NFT.
Check Ownership: ownerOf(uint256 tokenId) - Retrieves the owner of a specific NFT.
View Balance: balanceOf(address owner) - Displays the number of NFTs owned by an address.
Enhanced Security: Eliminates the risk of unauthorized access or forgery.
User Anonymity: Users remain anonymous while proving eligibility.
Reduced Fraud: Prevents reuse of proofs and unauthorized minting.
Scalability: Can be integrated into large-scale identity verification systems.
Exclusive Memberships: Only verified members can access NFT-based communities.
Digital Certificates: Securely issue and verify educational or professional credentials.
Access Control: Restrict access to certain services based on NFT ownership.
Gaming and Metaverse: Enable anonymous yet verified in-game asset ownership.
