Very few organizations will willingly apply decentralization to their system when they make insane amounts of money off of their centralized assets. It's a lose-lose scenario in their eyes, so the majority of successful companies eyeing the blockchain are really just pointing and laughing. "You mean they can buy our Netflix originals and not have to pay us a monthly fee to watch them? What a joke!"
We are off-topic regards the original question but I haven't found many people who seem to grasp this and is the reason I am very cagey about supporting any combination of gaming and blockchain. Publishers have spent years wrestling control away from players and moving everyone into walled gardens - like Netflix - where they can control your purchase agreements, or roll their own content markets. In what universe are these organisations going to knock down their centralised control and turn it over to a blockchain? It won't happen. I know Epic have made a PR point of saying they're open to blockchain but wait until the details are made clear for all to see. I guarantee it won't be what people think.
That's fine - and in the late 90's someone could have said the same about the internet. But there were already a bunch of real companies doing real things (like amazon, ebay, yahoo). They were new companies.
The post is asking - what are the real things being done. They will likely be done by new companies to be sure, but it doesn't change the question.
