A brief introduction to Dlive from someone who knew about and used it (as a viewer) before TRR joined up.
Dlive is a video hosting and streaming service. Technology-wise, it's not all that different from Twitch or YouTube in that regard. The videos it hosts and broadcasts are
not on a blockchain.
That being said, Dlive used to be integrated with the Steem blockchain. Aside from handing user-to-user token transactions like Bitcoin and Litecoin and such, the Steem blockchain allows users to attach long text messages to transactions, or replies, upvotes and downvotes/flags on existing messages. The Steem blockchain generates tokens regularly to users based on the upvotes they have received. Front ends for the blockchain can use these features to present various interfaces for these features. The most widely used interface is
Steemit, which presents the blockchain like a blog/forum site somewhere between Reddit and Livejournal, where users can upvote good posts and comments or flag bad ones, but there are other interfaces which display the content of the blockchain more like a standard forum, or like an image hosting site (though the images themselves cannot be hosted on the blockchain; just links to them), or like a microblogging site, or so on. (Some people conflate Steem and Steemit as the same thing, but technically they are not; Steem is the underlying blockchain, and Steemit is the most popular, but one of many, interfaces with which to view the content of, and add content to, the blockchain.)
So Dlive used the Steem blockchain as the back end of a video hosting site; you could use your blockchain keys to log in to your Steem "account," post comments to videos, upvote or downvote videos or streams, or tip streams with Steem's tokens. (Confusingly, the Steem blockchain actually has three "official" tokens on it.) But again, the blockchain only stores links to these videos or streams; it cannot store the videos or streams themselves.
A couple months ago, however, Dlive, for whatever reason, switched from using the Steem blockchain to this in-house Lino one - and promptly lost a lot of users. The Steem blockchain is widely supported enough that there are a fair number of places where you can exchange its tokens for other ones such as Bitcoin, which can then be easily sold for real fiat currency, and the order books (that is, the databases of offers people have placed to exchange X units of token A for Y units of token B) are wide open. Lino's tokens are, as far as I can tell, only exchangeable for Bitcoin or USD on Lino's site itself, and there is no order book, so who knows if the rate they're selling them for is accurate to how the market really wants to valuate them. Perhaps that will change in the future, but for now, the value of the "ice creams" that Ralph is getting is more or less whatever Lino says they're worth. And as far as I can tell, Lino's blockchain, if it really is one, doesn't support video hosting or streaming either - they're still using standard architecture for that stuff.
tl;dr: Dlive/Lino is sketchy. Videos/streams are not on blockchain and not at all uncensorable. If you want to gib shekels, use Streamlabs rather than Lino.
