But while the video game seemingly looks and plays much like other online strategy games, under the hood it's a very different story. That's because it doesn't rely on the servers running popular online strategy games like Eve Online and World of Warcraft. Instead, Dark Forest runs completely on a blockchain, in a way that means no one is in control of how it plays out. Its early success doesn't just reflect a fun way of making games that work in an entirely different way. It also helps prove that blockchains can be used for far more interesting and complex applications than just moving digital money around, something some blockchain boosters have been saying since the technology first emerged.
