Blockchain in Food Safety and Traceability

 Blockchain in Food Safety and Traceability

1. What Challenges Does It Address?


Food supply chains are often fragmented and opaque—products pass through multiple hands, making it easy for errors, fraud, contamination, or mislabeling to occur. Traditional traceability systems, often based on paper or siloed digital records, are slow and unreliable in emergencies.

2. How Blockchain Helps


End-to-End Immersive Traceability

Blockchain records every step—from farm to fork—creating a tamper-proof digital history. This enables rapid tracking and public verification via QR codes or scans.
