I don´t know if I am the only one who has seen the admin Theymos is having its own nickname on its public key. And I also don´t know if there is some thread with this topic. How can I put a nickname to my public key for when somebody goes to blockchain.info and put my address in the searcher appears my user electrobit instead of bitcoin address. Thank you.
As a beginner, like you, I do not know About this this,either.
But i have seen such public keys containing a nickname.
I had no idea how it works until now. I did a little search and here is what I found.
this might be helpful for you.
