To make this super clear. Qtum helps bridge the gap but is its own chain in its own right. A community member wrote up a really nice explanation I want to post here:
"@moxie Are you the moxi who wrote the article? There is some false information on that page. In the comment section moxi writes: "Yes, your thinking is spot on! Qtum has the ability to move smart contracts between the two chains. ", which isn't true. Qtum is built using Bitcoin and Ethereum code but operates independently of both networks (Bitcoin isn't even touring complete with their Scrypt system). When Qtum says they bridge the gap between the two communities, what they are trying to say is that due to the fact they borrow code from both projects, both their ecosystems are compatible with QTUM's i.e. Bitcoin payment gateways can be made to support Qtum aswell with minor modifications and Ethereum Smartcontracts can also be very easily ported to QTUM. People from both communities can be united in the Qtum project. I think a lot of people don't really understand this."
