I've seen many STEEM competitor and none of them convinced me that they were going to be a threat. But coming from @dan and Block.One I can see this being something powerful. I got this message when I try to watch the Keynote:

We use a special authentication system to make sure every user on Voice is an actual person. No robo-mobs. No catfish. No burner accounts.

I wonder if this would be too privacy invading and end up being like the Sesame Credit system on blockchain. I'd rather see something like Civic being used for identity verification.
