RE: Do you know Dtube's Dirty Little Secret?
Important information, thanks for the update. Love to hear that they are giving back to creators and curators, good rewards leads to more quality content and more Steemians... win-win.
One thing I still dont understand is how Dtube stores the video on the blockchain, does it? Is it locked in there forever? Or is it one day erased due to "storage" and "bandwidth" costs? I heard that somewhere, but doesnt that mean its not "immutable"? I though Steem platform made all the posts secure and immutable forever, stored in perpetuity?
It is not. Videos, like images in posts, are stored using the IPFS protocol, what is stored in the blockchain is the link to the gateway which enables people to see the video.
What makes IPFS really great is that, as more people sees the video -when using an IPFS client-, the more faster other people will be able to download it.
Busy is also using IPFS for storing images.
Honestly I have no idea about storage, its something I need to really learn about ASAP.
What little I know, I think the video is NOT stored in the blockchain, its just linked to on the chain. Meaning the chain has the link, not the video and therefore the video which is stored externally, on bandwidth they pay for, is where you have your actual video. So when the video is X amount old, they stop storing it because it costs something to keep it.
I may be wrong. That's what I heard.
The @dtube videos are stored using the decentralized IPFS protocol. IPFS doesn't guarantee the file gets hosted in perpetuity. However, it does ensure that if anyone is willing to host the file, that it can be hosted in perpetuity. With existing centralized services, you cannot step in to host the content if they go down. IPFS changes this and thus while not a complete solution is a huge step forward.
See for example what happened here. @andrewagostini, a new Steem user, posted an amazing @dtuve video. However, the video was very high resolution and took a while to load. In fact it was almost impossible to watch. Thus, I set up an IPFS node so I could mirror his video, allowing more users to watch it without lag.
That is really helpful information. Thank you for filling in that picture a bit better.
