Blockchain automates and streamlines record-keeping processes, reducing the need for manual documentation and intermediaries. Smart contracts—self-executing contracts with terms directly written into code—can automate transactions and enforce compliance, reducing delays and costs. For instance, payment can be automatically released to a farmer once the delivery is confirmed, ensuring timely and accurate transactions.
Combating Food Fraud
Blockchain helps combat food fraud by providing a secure and verifiable record of transactions. Each transaction is cryptographically linked to the previous one, making it nearly impossible to alter or falsify information without detection. This ensures that all claims about a product’s origin, quality, and authenticity can be verified, protecting consumers from fraudulent practices.
Enhancing Food Safety
Blockchain enables rapid and precise traceability in a contamination or outbreak. By accessing the blockchain, stakeholders can quickly identify the source of the problem, isolate affected products, and take corrective actions. This minimizes public health risk and reduces recalls’ economic impact. For example, in the case of an E. coli outbreak, blockchain can help trace the contaminated batches back to the specific farm, enabling targeted recalls and preventing further spread.
