Trustchain
About the Project
The Supply Chain Management Verification System is a decentralized platform designed to authenticate products across global supply chains. It leverages Verifiable Credentials (VCs) and Decentralized Identifiers (DIDs) based on W3C standards to ensure legitimacy at every step. The backend is built with Node.js and integrates Cheqd’s decentralized identity network for secure verification processes. On the frontend, a responsive React.js interface allows users to scan QR codes, upload files, or input credential data to verify authenticity in real time.
Key Purpose
The core purpose of this system is to establish transparency, trust, and traceability within supply chain ecosystems. By verifying product credentials at multiple checkpoints, it helps eliminate the risk of counterfeiting and unauthorized distribution. It empowers manufacturers, logistics providers, and retailers with reliable tools to validate product origins and issuers. Additionally, its modular design allows for diverse verification options—text, file, or QR—making it accessible across various user environments.
Key Features Developed
▫️Verifiable Credential Issuance & Verification: The system allows trusted entities to issue digital credentials that verify the authenticity and origin of products, using W3C-compliant standards and Cheqd’s decentralized identity tools.
▫️Multi-Device Responsive Interface: A sleek, responsive frontend built with React and TailwindCSS ensures seamless user experiences across desktop, mobile, and tablets.
▫️Flexible Verification Methods: Users can verify products via file upload, manual text input, or QR code scanning—catering to diverse use cases in the supply chain.
▫️Four-Point Security Check: Each credential undergoes robust verification for digital signature validity, issuer trustworthiness, revocation status, and expiration.
▫️Detailed Credential Viewer: A built-in credential viewer modal displays full VC details, including issuer metadata, credential subject, and cryptographic proof, offering complete transparency and traceability.
How It Works
▫️Credential Issuance: A verified authority (e.g., manufacturer) issues a Verifiable Credential (VC) for a product using Cheqd’s identity SDK.
▫️Credential Sharing: This VC is embedded in the product’s QR code, downloadable as a file, or shareable via a secure link.
▫️User Access: The end-user (e.g., distributor or retailer) scans the QR code or uploads the VC through the platform’s intuitive frontend.
▫️Verification Engine: The backend processes the VC through Cheqd’s verification service, checking issuer identity, digital signatures, revocation status, and expiration.
▫️Result Display: The platform displays a full report, showing whether the product is genuine, along with trust level, issuer info, and metadata.
Conclusion
This system offers a secure and decentralized solution for product verification using cutting-edge technologies like blockchain, DIDs, and VCs. It modernizes traditional supply chain processes by embedding trust directly into the flow of goods and data. With a scalable, mobile-ready frontend and a robust backend, it is adaptable to real-world industrial use cases. Ultimately, the platform ensures product integrity from source to shelf, building consumer trust and reducing fraud globally.
