RegiTrust

Blockchain Based Land Registry App

RegiTrust is designed to streamline the process of land registry using blockchain technology. By leveraging blockchain's properties such as immutability and transparency, the project aims to create a secure and efficient system for recording land ownership and transactions. This not only simplifies the process of accessing land records but also helps in reducing crimes such as scams, bribes, and illegal encroachments.

Introduction

The primary purpose of the Blockchain Land Registry App is to provide a digital platform for managing land registry records efficiently. By utilizing blockchain technology, the project ensures the integrity and transparency of land ownership records, making it easier to access and verify property information.

Features

• Cross-platform functionality using Dart and Flutter.
• Compatibility with the Polygon blockchain network.
• Functionality to showcase land area on a map using Mapbox API.
• Local testing capability using Ganache.
• Utilization of blockchain characteristics such as immutability and transparency.
• Transfer of ownership requiring authentication from both parties.
• Generation of a receipt upon successful land transfer.

Installation (Polygon)

To install the project, follow these steps:

1. Clone the repository to your local machine.
2. Ensure that Flutter and Dart are installed on your system.
3. Install truffle via npm npm install -g truffle.
4. Setup account on Alchemy and project on the Polygon Amoy Testnet.
5. Refer to Amoy api and documentation on alchemy and make changes to truffle-config.js and other source file accordingly.
6. Run:

truffle init
truffle compile
truffle migrate --reset

7. Copy the contract address as shown below and paste in contract address variable in lib\constant\constants.dart

8. Install any dependencies using flutter pub get.
9. Run the project using flutter run -d web-server --web-port 5555
10. Ensure that Metamask is connect to the same network as the Application and add the required wallets.
11. If need of funds for gas head to https://www.alchemy.com/faucets/polygon-amoy
12. Run the web interface on http://localhost:5555

Installation (Non Polygon)

To install the project, follow these steps:

1. Clone the repository to your local machine.
2. Ensure that Flutter and Dart are installed on your system.
3. Install truffle via npm npm install -g truffle.
4. Install and Start Ganache
5. Run:

truffle init
truffle compile
truffle migrate --reset

6. Copy the contract address as shown below and paste in contract address variable in lib\constant\constants.dart

7. Install any dependencies using flutter pub get.
8. Run the project using flutter run -d web-server --web-port 5555
9. Ensure that Metamask is connect to the same network as the Application and add the required wallets.
10. Run the web interface on http://localhost:5555

Usage

The usage of the Blockchain Land Registry App involves the following steps:

1. Users create their accounts and get verified by land inspectors.
2. Users add land details, including area, price, address, and documents.
3. Land inspectors verify the land details.
4. Users can choose to sell their land, and buyers can send buy requests.
5. The transfer of ownership requires authentication from both parties and generates a receipt.

Technologies Used

The project utilizes the following technologies, frameworks, and APIs:

• Dart and Flutter for cross-platform development.
• ImageBB API for document uploading.
• API for Ethereum to INR conversion.
• Mapbox API for capturing map coordinate data.
• Solidity for smart contracts.
• Truffle for connecting smart contracts with the network.
• Ganache as a local development network.
• Polygon AMOY network for testing and development.
