# 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 monitoring a blockchain network and notice that an attacker is attempting to catch up to the current block. They have not made significant progress in the first few attempts. What should you do to ensure the security of the network?

* [x] Increase the network's hashing power to make it even more difficult for the attacker to catch up.
* [x] Monitor the attacker's progress closely and prepare to implement additional security measures if necessary.
* [ ] Ignore the attacker's attempts since they are unlikely to succeed.
* [ ] Inform the attacker that they should stop trying to catch up.

**Notes to Learners**

In this scenario, it is crucial to recognize that the probability of an attacker catching up decreases exponentially as they fall further behind. By increasing the network's hashing power, you make it even more challenging for the attacker to succeed. Additionally, monitoring their progress allows you to be proactive in implementing further security measures if the situation escalates. Ignoring the attacker or communicating with them is not advisable, as it does not address the potential threat to the network.

# 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/bitcoin-whitepaper-series/section-11-calculations-bitcoin-whitepaper/assessment-4.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
