🎲Zk-VRF
Zone Nine's initiative to enhance transparency in web2 gaming by using Zk-VRF to addresses a critical concern in online gaming: the fairness and unpredictability of game outcomes
What is Zero-Knowledge Proof Verifiable Random Function (ZK-VRF)?
Zero-Knowledge Proof (ZKP) is a cryptographic method that allows one party to prove to another that a statement is true, without revealing any information apart from the fact that the statement is indeed true. A Verifiable Random Function (VRF), on the other hand, is a type of public-key algorithm that produces a pseudorandom output which can be verified by anyone who has the public key. Combining these two, ZK-VRF provides a way to generate random values that are both unpredictable and provably fair, while also ensuring that the process remains transparent to all players involved.
Solving Transparency Issues in Web2 Gaming
In traditional web2 gaming environments, players often raise concerns regarding the integrity of random number generation (RNG), which is crucial for the fairness of games such as loot drops, enemy behavior, and other chance-based mechanics. The centralization of these RNG systems typically means that players must trust the game developers to not manipulate outcomes.
Transparent Randomness: By incorporating ZK-VRF, Zone Nine can offer a decentralized solution where the randomness can be verified by any participant without having to trust a central authority. This is because the output of the VRF can be independently verified using the public key.
Enhanced Security: ZK-VRF not only ensures the randomness of outputs but also keeps the process secure against attacks that might attempt to predict or influence the RNG outcomes. The zero-knowledge proof element guarantees that no additional information (like how the number was generated) is revealed except the number itself and its validity.
Auditability: Every instance of number generation is accompanied by a proof that can be audited by any third party. This means that the operations of the RNG are completely transparent and open to scrutiny, enhancing trust among players.
Reducing Cheating and Bias: By ensuring that the game mechanics are transparently fair, ZK-VRF helps in reducing cheating and bias in gameplay, providing a level playing field for all players.
Implementation in Games
Implementing ZK-VRF in a gaming context involves a few technical considerations:
Integration with Game Engines: The technology needs to be integrated with existing game engines, requiring collaboration between cryptographic experts and game developers.
Performance: Maintaining high performance while implementing cryptographic operations is crucial, as these should not interfere with the gaming experience.
Scalability: As the number of players increases, the system should efficiently handle multiple, simultaneous verifications of random outputs.
At Zone Nine, we are pleased to work with Orochi Network (https://orochi.network/) - the world leader in Zk research and application. We are able to access Zk-VRF with a latency of merely 15 ms, which will guarantee the realistic experience of our game will not be disrupted.
