airspace

Here’s a structured response for your project outline:

Inspiration

The idea stems from the growing need for preserving urban views, such as ensuring that high-rise buildings don't obstruct scenic vistas like the seafront or natural landmarks. By tokenizing air rights, we can introduce a new market for preserving or even leveraging airspace above properties for various purposes, ranging from preservation to real estate development. The inspiration is to innovate urban development by utilizing technology to protect or capitalize on airspace.

What it does

This project enables the tokenization of air rights above properties and also use genai agents to buy sell the minted NFTs All in one go. Users can purchase these rights to prevent developers from constructing taller buildings that would block desirable views or for other urban planning needs. , with full property metadata stored in MongoDB Atlas. It facilitates the minting, transfer, and verification of NFTs through smart contracts, ultimately enhancing the accessibility and liquidity of airspace ownership.

How we built it

Backend:
- Smart Contracts: We developed smart contracts using Solidity to handle the minting and transfer of NFTs representing air rights. These smart contracts are written and tested using a Gen AI agent.
- Data Storage: MongoDB Atlas is used to store comprehensive property metadata, including the maximum number of floors allowed, current floors, and location details.
- Blockchain: We used sepolia test net to deploy our contracts and also used IPFT Pinata for storing the NFT metadata generated.
- USDC Payment Verification: We integrated a mechanism to verify payments (in USDC) before transferring the ownership of the NFT. -GenAI Agents: We used gen ai agents to with locally hosted llama models with help of ollama to deploy contracts to sepola and also perform verifcation on the public address of the participants. The agent is able to create its own contracts, deploy and hardhat config files.
Frontend:
- The frontend leverages Next JS, The user can choose to buy the listed NFTs, create legal agreements and aprrove them which then can execute smart contracts. This interface allows for interactive exploration of the value proposition.

Challenges we ran into

Integrating Complex Data: Pulling accurate property metadata from various local government sources proved challenging, as data is not always standardized or easily accessible.
Smart Contract Development: Ensuring that the smart contracts handled transactions securely and efficiently, especially with payment verification and NFT transfers, took extra time.
3D Map Rendering: Visualizing building heights and layering additional information in a 3D map was more complex than anticipated, especially with interactions for hover and property details.

Accomplishments that we're proud of

Successfully integrating blockchain with real estate data to enable the purchase and transfer of air rights.
Building a sophisticated and user-friendly frontend that presents the concept of airspace ownership in a visually appealing way using 3D mapping technology.
Completing the smart contract development and deploying it on the Midnight blockchain for testing purposes.

What we learned

How to bridge blockchain technology with real-world assets (air rights) in a secure, scalable manner.
The importance of ensuring that property metadata is accurate and accessible, especially when working with local government data.
Effective ways to use 3D map APIs to create a rich, interactive frontend experience.

What's next for airspace

Scaling: We aim to refine the system to support more properties and expand to other regions, providing a global marketplace for airspace transactions.
Collaboration: We plan to partner with local governments or trusted authorities for official verification and regulation of air rights transactions.
Refinement: The next step is to optimize the system for production use, focusing on security, user experience, and potential legal implications of airspace ownership.
