What is the relationship between this coin's devs and PayCoin (XPY) ?
The coin developer for ION has zero relation or affiliation to anything related to Paycoin or XPY.
So this Adam Matlack is a different Adam Matlack?

Adam helped write and edit the whitepaper, but is not a coin developer.
So if Adam "Paycoin" Matlack just wrote the ION whitepaper, who exactly is hiding behind the username ionomy here? A little bit of transparency would be nice.
Otherwise people could get the idea that ION is Paycoin 2.0
