Hi Sai.
You do not have any standard Blog template available in Episerver, but you can create a new PageData class to accomodate your blog post content. That enables you to contain the blog post information within Episerver CMS, but related information such as author, comments and tags though requires other Episerver features such as Categories, Episerver Social or Dynamid Data Store.
Read more about PageData here if that's a new concept for you.

Feel free to provide more details and I am sure we can help you in the right direction.
