# Assessment 4

#### Let's apply what you have learned so far to a specific scenario. Choose the most correct response (choose ALL that apply).

You are assisting a customer who wants to make an online payment using a new electronic payment system based on cryptographic proof. They are unsure about how their transaction will be secured and validated without a trusted third party. How do you explain the security features of this system to the customer?

* [x] Explain that cryptographic knowledge proofs ensure that the funds are secure and verifiable.
* [x] Inform them that digital signatures allow for quick validation of transactions without third-party involvement.
* [ ] Tell them that the system is completely unregulated and relies solely on user trust.
* [ ] Suggest that they should wait for a bank to verify the transaction before proceeding.

**Notes to Learners**

In this scenario, it's important to reassure the customer about the security of their transaction. Cryptographic knowledge proofs provide a secure way to establish custody over funds, ensuring that transactions are both secure and verifiable. Additionally, digital signatures facilitate quick validation of transactions, enhancing efficiency without the need for third-party intervention. It's crucial to emphasize these features to build the customer's confidence in the electronic payment system.
