I’m leaning towards double spending and maybe a planned fork, but I’m not confident about the third option. I wish we had more practice questions on this topic!

Cancelling transactions seems plausible too. I feel like we discussed how attackers could manipulate the network to invalidate transactions.

I’m not entirely sure about the unplanned fork. I remember it being mentioned, but I can’t recall if it’s a direct result of a 51% attack.

I think double spending is definitely one of the repercussions. It’s like what we practiced in that case study about blockchain vulnerabilities.
