"Trustable Food, Transparent Journey"
Matiru is a blockchain-powered agriculture supply chain platform that records every stage of the produce lifecycle - from the farmer to the consumer. It ensures transparency in pricing, quality, and origin, empowering all stakeholders and building consumer trust.
The traditional agricultural supply chain is often plagued by:
- Opaque Pricing: Farmers lack visibility into final market prices, leading to exploitation by middlemen
- Unreliable Quality Checks: Manual and inconsistent certifications are susceptible to fraud and manipulation
- Lack of Consumer Trust: Claims like "Organic" or "Pesticide-Free" are difficult for consumers to verify independently
- Inefficiencies and Waste: Poor traceability makes it challenging to manage inventory, recall contaminated batches, and reduce spoilage
- Farm-to-Fork Traceability: Every event in a produce's journey—from registration and transport to inspection and sale—is recorded on an immutable ledger
- Role-Based Dashboards: A tailored mobile app experience for each stakeholder:
- Farmers: Register produce, generate QR codes, and transfer ownership
- Distributors: Update location, split batches, and manage resale
- Retailers: Confirm inventory and log final sales
- Inspectors: Certify quality and record inspection results on-chain
- Immutable & Secure: Built on Hyperledger Fabric, all transactions are cryptographically secured and cannot be altered, preventing fraud
- Global Chain Access: A transparent ledger explorer allows authorized users to view all supply chain actions, fostering accountability
- QR Code Verification: Consumers can scan a simple QR code on the product packaging to view its entire history, ensuring authenticity and quality
The system is composed of three main parts:
- Hyperledger Fabric Network: A private, permissioned blockchain where organizations (Farmers, Distributors, Retailers, Inspectors) run peers. A smart contract (
chaincode) governs all business logic, such as registering produce, transferring ownership, and performing inspections. - NodeJS Backend: An API gateway that securely connects the mobile app to the blockchain network. It authenticates users and translates app requests into chaincode invocations.
- React Native Mobile App: A cross-platform application that provides a user-friendly interface for all stakeholders to interact with the supply chain. It includes offline support to ensure functionality in areas with poor connectivity.
- Blockchain: Hyperledger Fabric
- Frontend: React Native (Expo)
- Backend: Node.js, Express
- Database: CouchDB (for World State)
