Blog post on frontpage

Hi there, I need som help how to set up blog posts on my frontpage. I don't know if this is a GenerateBlocks or a GP theme matter. I have GP Pro and I can see there are some blog options here.

Here's the case, to create some content, and encourage users to sign up on my social network website, I want to show blog posts on my frontpage for all visitors, also non logged in users. But you have to be registered, and logged in to comment on posts.

In the blocks library there are some block under theme category, among that, a post list, but has this anything to do with the GP theme?

If not, what is the right way to add read only blog post for all visitors on frontpage?

Thanks!
