Decentralized Marketplace for Tokenized Real Estate

Overview

This repository contains the source code for a Decentralized Marketplace designed to facilitate real estate token transactions between authenticated users. The marketplace supports various real estate assets, including:

• Residences
• Garages
• Apartments
• Warehouses
• Lands

Each asset type includes the necessary fields to store detailed information about the property.

Technology Stack

Distributed Ledger Technology (DLT)

The marketplace is built on Canton, a scalable and privacy-enabled distributed ledger technology (DLT). Canton is responsible for:

• Handling all business logic securely.
• Maintaining an immutable and tamper-proof history of records and transactions.
• Ensuring data privacy and access control in a decentralized environment.

Smart Contracts and Execution

The Daml smart contract language is used to implement the business logic. These smart contracts execute on Canton, ensuring secure and auditable transactions. Daml provides:

• A safe and expressive way to define real estate ownership and transactions.
• Built-in privacy and fine-grained permissions.
• Automatic consistency and integrity enforcement in transactions.

Features

• Tokenized real estate transactions between authenticated users.
• Immutable and auditable transaction history.
• Smart contract-driven asset management.
• Fine-grained access control and privacy mechanisms.
• Support for multiple real estate asset types with structured metadata.

Installation & Setup

Prerequisites

Ensure you have the following installed:

• Daml SDK
• Canton
• Java (for Canton runtime)
• Docker (for deployment, optional)

Setup Instructions

1. Clone the repository:

git clone [email protected]:Badjarda/RealEstateMarketplace.git

2. Install the dependencies (for that run the following command in the root directory):

./scripts/get-dependencies.sh

If you are running it on WSL, do these commands

> dos2unix ./scripts/get-dependencies.sh
> sed -i 's/\r$//' ./scripts/get-dependencies.sh
> ./scripts/get-dependencies.sh

This procedure will download the required Daml packages.

3. Compile and run the project:

daml build --all


You need to have [Node.js] and [Daml] installed.

[Node.js]: https://nodejs.dev
[Daml]: https://docs.daml.com

First, start the Daml components:

```bash
daml start

This starts a server on http://localhost:3000.

See [documentation] for details.
