So about media on the chain.

I AM exploring various avenues to IPFS and watching the VCS proposal closely... either or both could lead to archival de-cent storage for stream replay VoDs (videos on demand) but for now, Im opting NOT to store live streams for a dozen reasons, and people can still save their own and upload them wherever now, or simulcast to venue that saves them or five of those at a time, with places like restream.io or streamyards services...

Once upon a time myself and another witness back then, sat one night on a discord call and created code between us that literally stored a copy of the star wars movie trailer onto (then steem) blockchain blocks. We were able to store it in chunks of video data in stringified text format, then reassemble and play it by retrieving, ordering and stitching the block content back together.

We also crashed the entire blockchain with that for something like 17 hours till all the witnesses were able to rewind and replay the chain to the point our "bad blocks" hit the chain :) Oops! Our bad! We took some shit for that :D
