What is DTube?
DTube is an application fully written in javascript, that runs in the browser, that allows you to upload and watch videos on top of the IPFS Network. Moreover, it uses STEEM as a database and enables earning rewards from your uploads.
This might ring a bell for those who remember the SteemQ project announcement, which made almost five thousand dollars in rewards, but never got released and ended up being rebranded - It's still not functional after more than a year, and even the current alpha uses a back-end server for everything and is therefore still centralized. I am sure I wasn't the only person disappointed by Steem.
