About The Project

In this project, I developed a Land Registration System using Hyperledger Fabric, a private blockchain, to securely store immutable land information and application details. Users can register and sell lands in a secure way. This solution will also prevent the possibility of selling a piece of land multiple times.

Built With

• Node.js
• Go
• Hyperledger Fabric
• MongoDB

In order to clone and run the project these have to be installed in your machine.

• git

  • Check if the installation was successfull or not with git --version and you should see a response like git version x.x.x

• Node.js with nvm

  • You'll be able to run the following command if you install nodejs:

    • node --version and get an ouput like: vx.x.x

• Go with gvm

  • You'll be able to run the following command if you install yarn:

    • go version and get an output like: go version gox.x.x

• Hyperledger Fabric

  • You'll be able to run the following command if the installation was successfull:

Usage

Start The Network

Type this command from the PropertyBlock/test-network folder:

This will start the Fabric Network with 2 Peers 1 Orderer and Certificate Authority Server for each.

Install Server Dependencies

Go to folder: PropertyBlock/chaincode-api/api

• Generate public & private keys for JWT authentication:

  • Run this command:
  • node generateKeypair.js This will create a public and a private key.

• Start the server with this command:
