- 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
