HiFi Gaming Society Integrates Chainlink VRF for Fair RNG in NFT Generation and P2E Gaming

We’re excited to announce that HiFi Gaming Society — a GameFi platform integrating Metaverse, NFT, and DeFi features to enable users to earn money and reputation for playing popular games from the past — has integrated Chainlink Verifiable Random Function (VRF) on the Binance Smart Chain (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 generate HIFI’s rarity-based NFTs and to offer randomized engagement incentives on the platform. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can earn NFTs and random rewards with varying rarity and gamified utility, which are distributed fairly and without bias.

HIFI’s rarity and utility-based, NFT collection debuts on PancakeSwap’s NFT Marketplace next month!

— Into the HiFi Verse!

In order to generate randomized NFTs and eventually activate our raffle system, 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 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 HiFi Gaming Society 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 HiFi Gaming Society is provably fair and was not tampered with by the oracle, outside entities, or the HiFi Gaming Society team.

Ape Kong Hi5VR is one of the rarest NFTs in our first collection and includes an immersive background.

HIFI will drop new NFTs weekly on PancakeSwap with the final set to be auctioned on HiFi Gaming Society’s ‘NFT Artcade’ launching in 2022.

We’ll continue collaborating with Chainlink, such as evaluating Chainlink Keepers as a solution for automating our rewards system for an improved user experience. We’ll also look into Chainlink Price Feeds when we list on new DEX or expand onto different blockchains.

“Chainlink VRF provides the trust and reliability our community expects when it comes to game/NFT mechanics, and we want to continue aligning with best-in-class blockchain infrastructure like Chainlink.”

About HiFi Gaming Society

HIFI is finalizing it’s successful (1000+ gamers) beta program and the whitelist/password protected site will soon be removed. HiFi’s gaming product is expected to soft launch shortly thereafter.

The GameFi P2E platform integrating Metaverse & DeFi earns users money daily to play evolving versions of classic games. HIFI is building multiple properties including HiFi Gaming (Platform), HiFi TV (1980’s MTV-vibe entertainment network for the joy of gaming, passion for NFTs, and culture of crypto), NFT Collections/Artcade (including Role Playing NFTs needed to enter the HiFi Verse). Each HIFI property connects in a value chain driving growth and value in tokenomics. Features include high score rankings, competitions, events, challenges, achievements, destinations, and streaming experiences via HiFi TV.

HIFI’s mission is to create pathways for gamers/streamers/artists/musicians to build a career and lifestyle on the blockchain. Simultaneously, we’re attracting gaming developers/studios to list their older games and reactivate revenue utilizing HIFI’s reward engine. Our gameplay economics platform is the game, our games and experiences are the rewardable services, and the gameplay analytics backend validates reputation driven by user participation in the ecosystem.
