Everyone on Open is anonymous so we won’t be able to tell you who are you chatting with.
The primary connection on Open is based on having another user's phone number in your phone contacts and they also have yours. You are automatically connect to people you know.
You are welcome to share your own name in conversations should you wish, and they may choose to do the same. The aim isn't to guess who people are, but rather to create a space for people to share more honestly without fear of judgment or criticism.
