Anonymity? Not sure that's a main goal here.

I thought consensus methods were more about ensuring all nodes are legitimate, so maybe option D is the right choice?

I feel like option B is close since it talks about security and the 51% agreement, but I'm not entirely convinced that's the main goal of consensus methods.

I think I came across a practice question that mentioned how consensus helps in validating transactions, but I can't recall the exact details.

I remember studying that consensus methods are mainly about agreement among nodes, but I'm not sure if it's just about security or something broader.

I'm a bit confused by this question. I'm not familiar with all of these tools, so I'll have to guess on this one. Hopefully I can narrow it down.

This seems like a straightforward question about project management processes. I'll need to think through the different processes and which one involves providing cost and schedule updates.
