# Assessment 6 #### What does "single source of truth" mean in a blockchain context? * [ ] Everyone stores their own copy of data, which they reconcile monthly * [ ] One company controls the master database that others access * [x] Everyone sees the same data simultaneously, with no conflicting records * [ ] A third-party auditor maintains the official records **Notes to Learners** The key insight is "same data, simultaneously." Unlike traditional systems where every company maintains separate records that must be reconciled, blockchain creates one shared version that all authorized parties can view in real-time. This eliminates the "he said, she said" disputes that consume so much time and money in current supply chains. --- # 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.
