Metagalaxy Land Integrates Chainlink VRF to Help Fairly Mint Planet NFTs
We’re excited to announce that Metagalaxy Land — a MMO strategy game based in the metaverse — has integrated Chainlink Verifiable Random Function (VRF) on BNB Chain mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to mint our Planet NFTs in a provably fair manner. Ultimately this creates a more exciting and transparent user experience, as users can independently verify that they have an equal opportunity to mint the planets with the most exclusive resources.
Metagalaxy Land is a MMO strategy game where players are divided into two categories: Cowboys and Space Pirates. Cowboys own planets and can terraform, manufacture high-value goods, construct ships, and hire Space Pirates. Space Pirates control a single spaceship and can join a Cowboy’s clans to fight for them in a joint quest to conquer the galaxy. Essentially, Cowboys are the brains and Space Pirates are the hired muscle.
All Space Cowboys are the owner of a planet, represented by a Planet NFT. Owning a planet in the metaverse gives Cowboys access to more features, such as constructing planetary and interplanetary manufacturing lines, terraforming planets, forging ships, and forming federations.
In order to distribute Planet NFTs to players in a verifiably random manner, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof about the integrity of the process.
After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by a time-tested oracle network, and secured through the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts.
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 Metagalaxy Land 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 the Planet NFTs minting process is provably fair and was not tampered with by the oracle, outside entities, or the Metagalaxy Land team.
“By integrating Chainlink VRF, our users can independently verify that the random number generator used in the minting process is provably fair and helps ensure that each player has an equal chance to mint the most valuable Planet NFTs.” — Can Gedik, CEO
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.
About Metagalaxy Land
Metagalaxy Land is a metaverse strategy and city-building game where different types of players work together to collect the awards and discover new artifacts. Metagalaxy Land’s major purpose is to provide its investors with the play2earn approach in addition to owning an NFT, which it has related to three key requirements.
Space cowboys in the Metagalaxy Land world will be able to transform their planets into new dwellings, scavenge for resources, and, most importantly, build their space pirate fleet over time.
