ADPP – Agri Digital Product Passport

Blockchain-backed W3C Verifiable Credentials Data Model v2.0 for traceability, QC certification, and digital product passport platform

Client: RVO – Netherlands Enterprise Agency

ADPP is an Agri Digital Product Passport concept designed for Malik Seed to make agricultural sourcing, quality control, certification, packaging, and supply-chain traceability more transparent and verifiable. The platform connects farm, hub, plant, QC, production, warehouse, and dispatch operations into a single traceability system. The proposed solution combines GS1/ISO-aligned data capture, batch and lot genealogy, offline QR-based operations, QC certificate verification, blockchain anchoring, and public verification pages. It is designed to support future readiness for GLOBALG.A.P., domestic certification bodies, exporters, retailers, and international compliance stakeholders. My contribution focused on shaping the product architecture, DPP positioning, blockchain certificate verification model, GS1 Digital Link strategy, ICP/L2 verification concept, role mapping, and portfolio-ready technical storytelling for client and CTO-level recommendation.
