Awesome! Excited to see this! 

 Yes, that sounds exactly like what I need! 
Please, keep me posted sir 🙏 . 

 Is blind auth already a thing somewhere else?
I found this: https://blog.mutinywallet.com/blinded-authentication/

Also, could it apply to Relays (and other services) too?  

 This made my day sir, btw. 

Finally feel confident enough to design for this.
