Peakd is just another frontend of hive.
What you share, it'll be in peakd as well.
check peakd.com/@(your username here)/posts
for example, peakd.com/@ashikstd/posts is for my blog.

and you may leave your link with just peakd.com instead of hive.blog (no matter where you publish the post).

I hope you understand, if not then ask me what you want to know.
