Let's see, can't you solve the exact same problem by simply having a centralized organization have a database of digital content ownership? Essentially a title record DB? Seems like it.
And how does your blockchain solution solve the problem of someone is hacking the game and needs to be banned? Can the EA ban them or do hackers get to stay for good because it's on the blockchain? And if EA can ban them at their discretion then how did the block chain solve anything here?
And so yet again someone appears to have thrown out "blockchain" when it provides zero value at all towards a solution.
Please anytime anyone proposes blockchain, please explain how it is in any way better than a separate centralized DB in your proposed use case.
