Not every system needs blockchain
Many business problems are solved with a secure database, role-based access, and strong audit logs. Blockchain should be considered when multiple parties need confidence in a shared record without relying on one central actor.
Traceability is a practical use case
Agriculture and food processing programs can benefit from trusted records around source, handling, processing steps, certifications, quality checks, and movement through the value chain.
Start with feasibility before development
A responsible blockchain project should begin with a feasibility study, stakeholder map, data model, governance approach, and comparison with simpler technical alternatives.
