What is a Bitcoin core and a Bitcoin Ultimate.

[TheWaiter]

Hi all,
So I have come across these terms and a lot of people are talking about them. I have looked around google for some explanations but all I can find are either a page that indicates how to set up them or some other trashy explanation. So what is a "Bitcoin Core" or a "Bitcoin ultimate"?

Thanks, (sorry for the newbie question)

Bitcoin Core are the developers behind the Bitcoin code.  They keep the code safe, secure and update it as needed or required based on consensus.  Bitcoin Unlimited was a development made by what is now Bitcoin ABC, who are the devs behind Bitcoin Cash.  It was a different suggested implementation prior to the Bitcoin Cash hard fork on Aug 1 when Segwit was implemented.   Hope this helps.  I am sure there are others that are willing and able to chime in more detail as well.
