Is Blockchain a Blackhole of Data? Help

in #blockchain7 years ago

Although I am new to Steemit, it seems to me that content
on the blockchain just slips off to a blackhole of data.
If there are millions of posts, how can content be searched
and returned to the present?

It seems the blockchain just continues to tick along
and what is created on the chain goes into nothingness.
What am I missing? Help?
