- Simplify the process of buying, selling, and transferring property.
- Enhance trust among stakeholders such as buyers, sellers, and regulators.
3. Key Components
3.1 Blockchain Platform
- Use Ethereum, Hyperledger Fabric, or Corda for secure record-keeping.
- Ensure scalability for managing a large volume of transactions.
3.2 Smart Contracts
- Automate processes like property transfers, tax payments, and lien management.
- Validate the authenticity of transactions and documents.
3.3 Decentralized Storage
- Use IPFS or Filecoin for storing detailed property documents and metadata.
- Maintain hash values of documents on the blockchain.
3.4 User Interface
- Develop portals for citizens, government officials, and legal entities.
- Include features like property search, ownership verification, and transaction history.
4. System Architecture
