Polyroll Sets Record for Chainlink VRF Calls As One of Polygon’s Top Dapps
Polyroll has conducted a successful launch of its decentralized gaming platform using the Chainlink Verifiable Random Function (VRF) to determine outcomes. By having random outcomes settled using a provably fair and tamper-proof random number generation (RNG) solution, Polyroll players have verifiable proof that the results are fair and follow stated odds. Random numbers used to dictate outcomes are backed by cryptographic proof verified on the blockchain, meaning outcomes are not manipulated by players, the oracles, or the Polyroll team.
These features have brought the highest level of integrity not only to the blockchain gaming industry, but the entire gaming industry as a whole. Unlike traditional games that run in black boxes, Polyroll runs on transparent, immutable and non-custodial contracts where the key input of randomness is powered by Chainlink VRF.
Our dapp has processed over 500,000 outcomes in our first 55 days and achieved the highest number of calls to Chainlink VRF by any one project. Polyroll plans to continue its use of Chainlink VRF for its existing games as well as its upcoming multiplayer games.
After reviewing various random number generation techniques, we chose Chainlink VRF because it provides strong proof around the integrity of the RNG process. 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. Polyroll’s smart contracts will only accept random number inputs if it has a valid cryptographic proof, and cryptographic proofs can only be generated if the VRF process is tamper-proof. This provides users with automated and publicly verifiable proof directly on-chain that each Polyroll game using Chainlink VRF for randomness is secure, provably fair, and unpredictable by all participants.
Polyroll is a decentralized gaming platform that runs fully on blockchain-based smart contracts. It is a non-custodial platform that does not require sign ups or deposits, eliminating a major pain point of traditional alternatives, where users risk losing their deposits if it becomes insolvent.
Polyroll currently offers 4 games: coin flip, dice roll, polyroll, and roulette — all of which use Chainlink VRF for verifiable randomness.
Through our play-to-earn program, players can earn ROLL tokens whenever they lose. This is icing on the cake, in addition to the cheap 1% house edge fees offered by Polyroll, bringing the effective house edge below 1%.
Through our dividend program, players can stake ROLL tokens to earn 50% of our house profits. Over $93,000 in house profits denominated in MATIC tokens have been distributed to ROLL stakers.
The play-to-earn program and dividend sharing program — on top of our existing features — makes Polyroll the most decentralized solution ever built. It is also testimony to the profitability of the platform since launch.
