hey @dwr.eth, I was reading your github docs today. 

First impression: the whole architecture is very neat and this will attract a lot of devs. I also have a few questions for you ⬇️

2. How can I design my own hub? Are you gonna release an sdk for that?

3. Did we already publish our FID on-chain? Was it done by some (meta?) transaction while signing up? (I don’t remember) 
What is our Farcaster Hub right now?

4. I didn’t understand Verification part (section 4.3.) Why would I use that? How is that different from the validation function?

5. How long ago did you start building farcaster?

1. Where does the validation function takes place? Is it implemented inside the Farcaster hub or on the application client side? Or both? And how do you enforce hubs to correctly perform verification on signed messages?
