GalaxyWar Integrates Chainlink VRF to Help Power Provably Fair Lootboxes 

In order to provide our community with exciting and provably fair loot box reveals, we are pleased to announce that GalaxyWar has integrated  Chainlink Verifiable Random Function (VRF). By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable random number generator (RNG) needed to randomize the contents of the GalaxyWar mystery boxes.  

Venturing Safely Across the Multiverse 

GalaxyWar comes to the NFT gaming market by way of Galaxy Studio, founded by chief developer Gru in 2009. His expertise and resume include over 2 decades of game development experience and a host of blockchain titles to his credit. The GalaxyWar game takes its inspiration from classic traditional games such as Roblox, Minecraft, and EVE Online. GalaxyWar is one of the first games to ever launch on the OKEx chain and features immersive multi-chain capabilities through the use of “Wormholes” (bridges). This enables players to travel and earn across several blockchains, which will include  Binance Smart Chain, Avalanche, Ethereum, Polygon, and Fantom in the near future. 

Randomness is a core feature of all games, and it was important to the GalaxyWar team to select an RNG that provided users with the ability to independently audit the randomness. However, most on-chain RNG solutions have not been proven to successfully prevent manipulation and the traditional solution of using block hashes is susceptible to being tampered with by miners or validators. On the other hand, opting for an off-chain RNG solution fails to provide evidence regarding the integrity of the selection process. 


After considering a variety of solutions to provide our users the highest assurances possible that GalaxyWar loot boxes are undeniably fair and unbiased, we chose to integrate Chainlink VRF—a time-tested solution for verifiable on-chain randomness. Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof.

The GalaxyWar smart contract will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This provides our users with automated and verifiable assurances directly on-chain that GalaxyWar loot boxes are provably fair and were not tampered with by the oracle, outside entities, or the GalaxyWar team.

“Removing trust is a core component of blockchain technology, and we felt it was necessary to extend those same features to the game’s RNG. By integrating Chainlink VRF, our users can be assured that we’re using best-in-class infrastructure to provide them with a fair experience when opening loot boxes—a great step towards building a truly player-focused game.”

Gru, founder of Galaxy Studios. 

About Chainlink

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
