## Week 3 and 4

This week’s primary goal was to finish the issue I had taken up, which involves preventing repeated CLI arguments from allowing the node to start. I have almost completed it. Just need to write unit tests before submitting a PR.

The issue I am facing is that when using boolean commands like besu **---privacy-enabled=true ---privacy-enabled=false**, the Besu node still starts. For single-value types (not arrays, sets, or lists), the last specified value overrides the previous one and is used.

We expect it to throw an error if the same argument is specified more than once.


Apart from this, I have also been researching EIP-7639, which is a project from the Besu team.

## Next Steps

* My goal for the coming week is to complete and close the above PR and continue researching EIP-7639
