What happens on a digital planet? Whatever the world’s rules-its “digital physics”-allow, he says. The deepest thinkers about Dark Forest seem to agree that while its use of cryptography is genuinely innovative, an even more compelling proof of concept in the game is its “autonomous” game world-an online environment that no one controls, and which cannot be taken down. Zero knowledge is also not the only focus at 0xPARC. It could also be possible to use zero-knowledge cryptography to prove that you’ve run a machine-learning algorithm on a sensitive data set while keeping the data private, says Gubsheep. You could prove you were above a certain age without revealing your actual age, or that you have more than a certain amount of money in your bank account without revealing the actual amount. Zero-knowledge proofs could make it possible to prove all kinds of things about yourself without revealing anything else. For example, one application the group is interested in is digital identification.

The scope of 0xPARC is not limited to gaming. Bhardwaj recently did a stint as a 0xPARC intern. Gubsheep and others have even launched an R&D organization, called 0xPARC (a reference to PARC, the storied R&D company that Xerox launched 40 years ago), to support this work. Developers and computer scientists inspired by Dark Forest are already exploring new games and applications that take advantage of zero-knowledge proofs.

First, it demonstrates how advanced cryptography can be used to add new features to online worlds.

To Bhardwaj and other true believers, Dark Forest is proof of several new concepts at once. They see Dark Forest as the first step toward rich digital realities-some might call them metaverses-that are run by decentralized networks instead of company servers.ĭark Forest is not only the most complicated blockhain game, says Bhardwaj: “I do not think there is an application on the blockchain that is more complex.” By designing it to run on a blockchain, the game’s creators also produced technical infrastructure that broadens the scope of how we might use blockchains to interact online, he argues.

Some of them, like software developer Nalin Bhardwaj, have been inspired by the game’s technical underpinnings to stay and work on the Dark Forest universe-and build new Dark Forest–inspired games. Since February 2020, more than 10,000 people have played. Every time players move, they send a proof to the blockchain that the move is valid-without revealing their coordinates in the universe. The hidden areas become visible only if the player explores them. What they built, however, has hinted at new possibilities they didn’t fully anticipate.ĭark Forest is the most complicated blockchain game to date, and the first of its kind to feature what game theorists call “incomplete information.” When a new player first arrives in Dark Forest, most of the universe-including potentially hostile opponents-is hidden. Gubsheep and his friends achieved what they set out to do: make a cool, sci-fi-inspired game using cutting-edge cryptography. Despite all the initial hype around a wide range of non-finance uses for blockchains, the popular perception now is that using blockchains makes sense only for simpler, finance-related applications. Blockchains are slow and expensive to use-far from ideal infrastructure for a game that must keep track of many interconnected systems and a vast number of player moves.

They knew it was a “pie-in-the-sky” idea. He acknowledges that it would have been technically possible to write the game in a traditional server so that its entire history would be viewable, including every zero-knowledge proof-“but at that point you’re basically starting to build a blockchain.” They wanted to build the game in a way that would allow everyone to be able to check that “the mathematical protocol underlying the game is being followed correctly,” says Gubsheep. Shortly thereafter, he convinced two friends to help him build it.Įventually, Dark Forest’s creators decided that to make it work they’d need to use a blockchain. When he got home, he stayed up all night sketching out the idea. Gubsheep began to imagine a “cryptographic Dark Forest” in which opposing players would be like civilizations “tiptoeing” through a universe filled with potentially hostile counterparts-hidden from view thanks to zero-knowledge proofs. The most prominent example is Zcash, a Bitcoin-like cryptocurrency that uses a class of zero-knowledge proofs called zk-SNARKs-the same kind Dark Forest uses-to hide transaction data so that users can deal anonymously, almost as if they were using a digital form of cash. The idea behind zero-knowledge proofs dates back to the 1980s, but some of the first practical applications have appeared recently in blockchain systems.
