QORPO Integrates Chainlink VRF With CyberTrade NFTs

We’re excited to announce that Qorpo–a blockchain gaming company–has integrated Chainlink Verifiable Random Function (VRF) on Binance Smart Chain. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to generate randomized attributes for NFTs used within the CyberTrade game.

CyberTrade is a P2E (Play-to-Earn) NFT game with multiple types of game modes, team battles, and drag races. The game revolves around NFT cards that can be minted for free and represent fighters, race cars, bosses, and items. Each card has different attributes based on what type of card it is.

There will be special characters you can play with in the city of sin, Metropolit. The city of Metropolit is a futuristic city in the year 2101 that has been largely taken over by big corporations after a technological revolution. These corporations have taken control over a wide range of areas, such as weapons, robotics, pharmaceuticals, and communications, and most of them operate above the law. This has pushed many individuals with no family, fortune, or corporate connections into the streets with no way of getting a decent job.

To randomize attributes of our NFTs within specified ranges, we needed 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 time-tested oracle infrastructure, 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 CyberTrade smart contract will only accept the random number input if it has 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 CyberTrade NFT attribute distribution process is provably fair and was not tampered with by the oracle, outside entities, or the Qorpo team. This ultimately makes the game more unique and fun to play.

“Chainlink proved itself as a VRF leader and it is exactly what we’ve been looking for, so we decided to implement it in our upcoming game CyberTrade. We believe all users will benefit from this update greatly.”

— Rastislav Bakala, CEO of Qorpo
