# Assessment 5 #### What does "single source of truth" mean in the agriculture blockchain context? * [ ] One company controls the database with all farm records * [x] Everyone in the supply chain sees the same verified data simultaneously, with no conflicting records * [ ] Government agencies maintain centralized agricultural records * [ ] Farmers must submit all data to a central blockchain authority \ **Notes to Learners** "Single source of truth" doesn't mean centralized control—it means **shared visibility**. Your farm records harvest data, your distributor confirms receipt, your retailer verifies delivery, your certifier validates compliance—all recorded on the same blockchain. Everyone sees the same data at the same time. No conflicts. No reconciliation meetings. No "your records say X but mine say Y." This is fundamentally different from centralized control (options A and D) or government databases (option C). **The power is in the sharing and verification, not in centralization**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
