I’ve heard of this but I never got around to looking much into it. There are quite a few interesting things I think and hope blockchain will brining to the gaming world. I can only hope further transparency when it comes to buying or selling game lances keys to play something. I would love to be able to resell old games I just have no use for many more or never really liked. Something I look forward to being more o f a thing when block chain technology is adapted more.
One of the more annoying things is losing saved file data! That sounds like an interesting way to protect against such issues.
