RPS League announced this Thursday, December 30, through its Twitter account, its official integration with Chainlink, the verifiable random function (VRF) in the BSC main network.
“We are pleased to announce that the RPS League has officially integrated the Chainlink Verifiable Random Function (VRF) into the BSC mainnet. By integrating the industry-leading decentralized Oracle network, we now have access to an auditable and tamper-proof source of randomness needed to create mystery boxes in a demonstrably safe and fair manner. Ultimately, this creates a more exciting, transparent and fraud-proof user experience, as users receive strong guarantees that the contents of the mystery box are randomly generated when purchasing NFT”, he said through an article published in the Medium platform.
The company stated that, in order to help make its action Open the box is random access that we need a secure random number generator (RNG) that any user could do an independent audit. However, RNG solutions for smart contracts require several security considerations to prevent tampering and ensure system integrity. For example, RNG solutions derived from blockchain data, such as block hashes, can be exploited by miners / validators, while off-chain RNG solutions derived from off-chain APIs are opaque and do not provide users with a definitive test of the integrity of the process.
In addition, he highlighted that after reviewing various solutions, we selected Chainlink VRF because it is based on state-of-the-art academic research, backed by a time-tested Oracle network and secured by generating and on-chain verification of cryptographic tests that test the integrity of each random number provided. to smart contracts.
The company explained that Chainlink VRF works by combining block data that is still unknown when the request is made with the previously compromised private key of the Oracle node to generate both a random number and a cryptographic proof. The RPS smart contract will only accept random number input if it has valid cryptographic proof, and cryptographic proof can only be generated if the VRF process is tamper-proof. This provides our users with automated and verifiable assurances directly in the chain that Open Box smart contracts are provably fair and are not tampered with by the oracle, outside entities, or the RPS team.

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