Okay, I admit it; that subject line is _more than a little_ hyperbolic (it got you to read this message though ;-). If anything, CCP Games is actually downplaying any connection of their latest game - "EVE Frontier" - has to the blockchain; it's barely mentioned, while they are quick to quash any rumors that the blockchain is coming in anyway to "EVE Online".
Still, they've remained firm on the idea that there will be blockchain technology. Although details are scant, it would allow for a third-party marketplace where users could buy and sell in-game assets or 'custom currencies'. Of course, there's no actual advantage to this; sure, I could buy 10,000 hydrogen or 200 ISK or a star cruiser via blockchain... but I can still only use those things in the game itself. It has no value outside of "EVE Frontier", so there's really no point to not selling it through the official marketplace. The only advantage is to those who speculate on the value of such worthless digital knickknacks, which does nothing to make the game more playable or accessible to anyone _outside_ of that community of speculators. It's a bad idea all around.
EVE fans are almost overwhelmingly opposed to the idea. The fact that crypto games attract the worst low-life scammers probably does nothing to make the idea any more palatable. I can only assume the concept is pushed by somebody at CCP Games that has an overly large investment in Ethereum (the crypto-coin that's backing "EVE Frontier's" blockchain) and is desperate to drag some new rubes into that marketplace to prop up the value of their nonsense-money. It just doesn't seem a worthwhile investment to design an entire game around otherwise.
