This solution implements a blockchain-based real estate platform in which each property is digitally represented as an ERC721 non-fungible token (NFT). Zero-knowledge proofs (ZK-SNARKs) are utilized to ensure confidential ownership verification. The platform is developed with Solidity, ZoKrates, and features integration with external NFT trading platforms such as OpenSea.
- Property Tokenization: Real estate assets are individually tokenized as ERC721-compliant NFTs on the Ethereum blockchain.
- Confidential Ownership Verification: Title ownership can be validated using ZK-SNARKs, constructed and verified through ZoKrates, preventing exposure of non-essential personal or transaction information.
- Marketplace Interoperability: NFTs are compatible with external marketplaces and can be listed, transferred, or traded. Test deployment integrates with OpenSea (testnet support available).
- Smart Contract Development: Solidity, Truffle, OpenZeppelin ERC721 modules.
- Zero-Knowledge Proofs: ZoKrates framework for constructing and validating ZK-SNARKs.
- Development Tools: Docker for containerized environments, Infura for decentralized node access, Remix IDE for interactive contract management.
- Clone the repository and install dependencies:
npm install - Deploy the contracts to the desired network, for example:
truffle migrate --network rinkeby - Mint property NFTs via Remix IDE or directly through OpenSea integration.
