InspirationInspiration

Farmers produce high-quality crops but still earn low income due to middlemen, document fraud and unsafe international payments. Buyers also struggle to verify product authenticity and track shipments. We wanted to build a system where farmers can sell globally with trust, transparency and guaranteed payment — without intermediaries or fraud.

What it does

GramaToGlobal is a mobile platform that connects farmers directly to global buyers. It provides:

Blockchain-based escrow payments (money released only after delivery)

AI document verification to prevent fake certificates

GPS + QR shipment tracking in real time

Digital signatures for legally valid contracts

Tamper-proof export document storage

Result → Fair profit for farmers and full visibility for buyers.

How we built it

Flutter → farmer & buyer mobile app

Node.js / Django + REST APIs → backend logic and transactions

PostgreSQL + MongoDB → secure data storage

Polygon / Hyperledger → smart contract escrow and blockchain verification

OCR + ML → detects fake export documents

GPS + QR + WebSockets → live shipment tracking

AWS / Azure + Firebase + Docker → cloud deployment

Challenges we ran into

Integrating blockchain escrow with mobile app

Real-time GPS + QR tracking for both buyer and seller

AI model for document fraud detection

Simple UI/UX for farmers with low digital literacy

Accomplishments that we're proud of

Built a complete export system without middlemen

Implemented secure blockchain payment release

Developed AI-based verification of export certificates

Created transparent shipment tracking and contract signing workflow

What we learned

Real business use of blockchain beyond cryptocurrency

AI + smart contracts + GPS can stop fraud in the supply chain

Importance of simple and multilingual UI for rural users

Strong teamwork across mobile, AI and backend development

What's next for GramaToGlobal

Multi-currency global payments Buyers can pay in their own currency (USD, EUR, AED, etc.). The system auto-converts to INR and stores the amount in escrow until delivery — making international payments smooth and secure.

AI-based price prediction AI will analyze global market demand and price history to suggest the best price, best selling time and high-demand countries — helping farmers earn maximum profit.
