@donnadavisart Ntopaz is what we typically refer to as another "frontend" for the Steem blockchain. Similar to steempeak.com, busy.org, partiko, esteem, etc.

All these are their own interfaces and they can choose what and how to show information, but they're all accessing the same information from the Steem blockchain.

Sites like Steemit simply show everything. So does steempeak, busy, esteem, and steeve. Ntopaz, dtube, and Steepshot are frontends that only show posts that are posted on their particular platform. Hope that makes sense. :)
