Data immutability problem

[IShishkin]

Hi there. I'm curious about the public opinion on the following questions:
1) How do you understand the "data immutability" in the context of blockchain networks? What description of this feature would you suggest?
2) What does it mean to be a solution that ensures data immutability? What does it mean for data to be immutable?
3) How do various blockchain solutions approach to data immutability?

I understand blockchain immutability, but in your text you are basically asking same question 3 times, and your question is implying that there's a problem with data immutability but you are not telling us what that problem is.

Answer depends of the definition of your question and this could go in so many ways if i had to guess what you mean.

I thought that data immutability was not a problem but rather a desirable feature of blockchains.
Since we as cryptocurrency users expect the blockchain to offer unbiased and factual information for us all, if somehow the data was mutable or able to be changed, then wouldn't that imply there is a way to censor or alter information/transactions?

I guess there are some cases one can find information our there that is one does not want to be public, though.

I agree. The word "problem" projects a negative light on the subject. I'll edit my question and use the word "feature" instead.

Yes, you are right. That's what I'm looking for.
