# Assessment 9

#### True or False: Blockchain replaces EDI (Electronic Data Interchange) systems that companies currently use.

* [ ] True
*

&#x20;  False<br>

**Notes to Learners**

This is crucial for implementation. Blockchain doesn't replace EDI—**it enhances it**. Companies have invested decades in EDI infrastructure for exchanging purchase orders, invoices, and shipping notices. Blockchain adds three layers on top of existing EDI:

1. **Trust layer:** Cryptographic proof that data hasn't been tampered with
2. **Visibility layer:** All parties see the same EDI transactions in real-time
3. **Automation layer:** Smart contracts execute based on EDI data

Think of it as keeping your efficient document exchange system (EDI) while adding a shared, secure ledger (blockchain) that everyone trusts. This is why adoption is practical—you don't rip out and replace everything.
