title_body: What is the Cardano Stiftung? I have seen this mentioned a few times and have no idea what it is.
  I get the impression that it is referring to the combination of the Cardano Foundation, IO Global and Emurgo.
upvoted_answer: These are synonyms. Stiftung is German for foundation. The Cardano Foundation is located in Zug, Switzerland - a German-speaking part of the country.
  The twitter handle of the (now verified) Cardano Foundation is CardanoStiftung: https://twitter.com/CardanoStiftung.
