BetU Integrates Chainlink VRF For Fair Player Reward Payouts on BetU Fantasy

BetU’s new play-to-earn sports and esports fantasy betting game, BetU Fantasy, has integrated Chainlink Verifiable Random Function (VRF)

We’re excited to announce that BetU’s new play-to-earn sports and esports fantasy betting game, BetU Fantasy, has integrated Chainlink Verifiable Random Function (VRF) on BSC mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to select winners of our weekly consolation rewards. Ultimately, this creates a more exciting, transparent, and fraud-proof user experience, as all players will have an equal chance to receive rewards every week even if they didn’t finish at the top of the BetU Fantasy leaderboard. 


BetU Fantasy gives players the excitement and thrill of sports predictions without any risk. By placing fantasy bets on sports and esports events such as the English Premier League, NBA, UFC, Counter Strike, or Dota 2, players can earn thousands in crypto rewards every week. 


In order to give all players an equal chance of winning consolation rewards, 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 BetU 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 BetU Fantasy consolation rewards are provably fair and not tampered with by the oracle, outside entities, or the BetU Fantasy team.



In the future, both the BetU and BetU Fantasy platforms plan to integrate Chainlink Price Feeds to help power their internal cryptocurrency exchange.

“We wanted to give every player of BetU Fantasy a chance to win rewards, even if they weren’t atop the weekly leaderboard. By integrating Chainlink VRF, we have access to a highly secure and provably fair random number generator that allows us to verifiably prove that consolation reward winners were selected at random with no bias.” — the BetU Team.
