Bunicorn Will Integrate Chainlink VRF to Secure VBUNI NFT Collectibles’ Randomness
We’re excited to announce that Bunicorn — the all-in-one BSC-powered DEX — will integrate Chainlink Verifiable Random Function (VRF) on the Binance Smart Chain blockchain. By integrating Chainlink’s industry-leading decentralized oracle network, we can obtain access to a tamper-proof and auditable source of randomness needed to distribute our limited Super Rare & Legendary NFT cards to our users in an unbiased manner. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can have fun turning their time-locked VBUNI tokens into much more valuable assets by wrapping them up into unique NFT game cards which are distributed in a provably fair and verifiably random way.
Bunicorn offers high APY liquidity mining farms with a new NFT reward vesting model which turns user’s rewards into NFT collectibles. We intend to make a universe of gamified cards with unique artworks generated algorithmically similar to that of Crypto Kitties or Polkamons.
We rank the rarity of the NFT collectibles in 6 levels from Normal to Legend based on the number of underlying assets wrapped in that token and the duration of the vesting period. For instance, a BUNI token with a value of $1M locked in 1 month would be classified as Super Rare. Cards can be enhanced until a certain level at which they are fully mature (max).
All the Super Rare & Legend NFTs will have tailor-made design and limited supply. They’ll be distributed with the true randomness made by ChainLink’s VRF.
In order to guarantee all Bunicorn NFTs’ cards are distributed in a verifiably fair way for our users, 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 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, we 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 Bunicorn 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 Bunicorn is provably fair and cannot be tampered with by the oracle, outside entities, or the Bunicorn team.
“Since day one, we have always been sticking with our philosophy to prioritize transparency and fair distribution of all forms for our users. Therefore, it is very critical for us to choose a trusted and capable randomness provider that shares the same vision and helps us fulfill our promise to the community. And we see Chainlink VRF as the most suitable ally on this trailblazing journey as convinced by their powerful portfolios with proven know-how.” –Phuc Nguyen, Bunicorn’s Founder & CEO.
