# Assessment 7 #### Which statements about blockchain's tamper-proof records are TRUE? (choose all that apply) * [ ] Records can be changed if both parties agree * [x] Every change creates a permanent history showing what was modified * [ ] Only the system administrator can see the complete transaction history * [x] Attempting to alter past records is visible to all participants * [ ] Blockchain replaces the need for human decision-making **Notes to Learners** This question addresses a common misconception. Blockchain doesn't prevent authorized updates—businesses need to correct legitimate errors. Instead, it makes **any change visible and permanent**. If a delivery date needs updating, that's fine—but the original date and the change are both recorded forever. This transparency prevents retroactive fraud while allowing normal business corrections. And critically (answer E is false), blockchain doesn't make decisions—humans do. It just automates the execution of decisions that have already been made. --- # 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.
