Penguin Finance x Chainlink VRF Integration
Penguin Finance will integrate Chainlink Verifiable Random Function (VRF) on the Avalanche blockchain to secure the Penguin Arena Gamified dApp.
In order to securely and fairly determine the winners within the Penguin Arena game, they 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 using on-chain data like block hashes can be exploited by blockchain miners, while off-chain RNG solutions like traditional data providers are opaque and don’t provide users with definitive proof about the integrity of the process.
After reviewing various solutions, they selected Chainlink VRF because it’s based on cutting-edge academic research, supported by Chainlink’s time-tested oracle infrastructure, and secured through the generation and on-chain verification of cryptographic proofs that guarantee 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 Penguin Finance 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 users with automated and verifiable assurances directly on-chain that the Penguin Arena is provably fair and cannot be tampered with by the oracle, outside entities, or the Penguin Finance team.
This integration will not only power the Penguin Arena but also the Penguin NFTs themselves. Their core stats will be determined in a provably fair fashion along with the result of each duel. Penguin Finance will also leverage Chainlink’s Price Feeds within its Prediction Markets. This enables their users to predict price movements and receive rewards in a vast array of cryptocurrencies.
“After testing several off-chain and on-chain solutions to settle battles within our PvP game, nothing seemed to be both secure and fast. At least, that’s until we discovered Chainlink’s VRF. It is the industry’s gold standard for such applications. It’ll provide the safest, most convenient solution for our users playing on the battlegrounds.”
