Product Engineering Case Study
BlockTrack Technical Case Study
How LayerSeven designed a blockchain-powered supply chain traceability platform.
Problem
Agricultural and logistics supply chains can suffer from poor visibility, manual tracking, middlemen dependency, and limited trust between stakeholders.
Solution
Designed a full-stack traceability platform where supply chain actors can create, transfer, and verify product batches through structured workflows and blockchain-backed verification.
Core Features
Technical Approach
BlockTrack uses a traditional application database for fast querying and business workflows, while blockchain-backed verification is used for traceability and tamper-resistance. This avoids putting every operational detail directly on-chain while still preserving trust where it matters.
Outcome
Built a working product prototype demonstrating end-to-end supply chain traceability, role-based workflows, batch tracking, shipment management, and blockchain-backed verification.
This case study demonstrates LayerSeven's ability to model complex business workflows, design full-stack SaaS architecture, and use blockchain practically where traceability matters.
