I’m a bit confused about the options, but I don’t think tokenization or peer-to-peer networking are the right answers.

I feel like we've seen similar questions before, and I think the consensus algorithm is crucial for changes, so I'm going with A.

I remember discussing hash immutability in class, so I'm leaning towards B) Hash immutability, but it could be a trick question.

I think the answer might be A) Consensus algorithm, but I'm not entirely sure if that's the only feature involved.
