Myobu Integrates Chainlink VRF to Secure The “Fountain of Fortune” Giveaway Contract

Myobu integrates Chainlink’s VRF solution

We’re excited to announce that Myōbu, the project which plans to give back more to its community than any other project in the cryptoverse has integrated Chainlink Verifiable Random Function (VRF) on the Ethereum mainnet. By integrating Chainlink’s industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to select a random user from the pool of all users who contributed to the fountain contract. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can be certain that the contract will work, and cannot be exploited in any way.

This means users can contribute ETH to the Fountain of Fortune contract, receive their tickets in exchange and then the winning ticket will randomly be selected from the list of pooled users via the Chainlink VRF. This will all be done automatically in a trustless, immutable way. (Which is essential for a protocol which will process millions of dollars worth of contribution & distribution.)

The Fountain of Fortune explained

In order to ensure the winner is truly selected randomly, 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. This Myōbu 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 the Fountain of Fortune is provably fair and cannot be tampered with by the oracle, outside entities, or the Myōbu team.

Chainlink’s VRF explained (simplified)

As Myōbu expands, the project will continue to evolve and create new & exciting ways for the community to enjoy more fun, useful and rewarding features. Whenever an oracle is needed, Chainlink is the obvious choice. Whether it will be a “pick the price” game or a “random draw winner” contest, our smart contracts will integrate Chainlink solutions to make this a trustless experience.
