I got to know about it recently, when someone used it to make video for Morpheus lab and then I asked, was told it is an affiliate of steemit, once you have an account with steemit, you automatically can use it, your steemit followers are also your DTube followers. You also earn when you get upvote using DTube.
That is true. Although completely separated companies, DTube is working together with Steemit.
What does this mean?
When you upload a video (or tag, or comment) on DTube, you can rewarded with both DTC (DTube Coins) and STEEM.
Blockchain were made interoperable, in order to avoid the silo effect.
We think facilitating interactions between chain will be a way of going mainstream (as Youtube and Facebook collaborates together for instance).
By the way, there is just one week remaining for claiming your DTube account, if already have a Steem account, so better hurry if you haven't.
All the best,
DTube team
