DFSocial Implements Chainlink VRF to Secure Randomized Outcomes on Its Gaming Protocol

6 min readJul 20, 2021

DFSocial Gaming is committed to our Gamers & Sponsors — first and foremost. Whether it’s offering the widest selection of games, adding new ways to reward our users in crypto, or ensuring the platform is as efficient and secure as can be, no stone will be left unturned in our quest to see DFS rise to the top based on input from our loyal community.

It has been quite a ride since the platform went live six months ago, resulting in tremendous growth in users and supporters thus far. However, we are not stopping there — we have integrated Chainlink VRF to expand the DFS ecosystem on Binance Smart Chain, enabling new types of assets and applications on our platform based on provably fair randomness, such as dynamic NFTs, giveaways, and mystery boxes. We are also looking to use Chainlink to bring other types of data on-chain, including gaming data for various results and statistics.

Chainlink was the logical oracle solution for DFSocial because it is the most widely used, time-tested, and easy-to-integrate oracle network in the industry. Chainlink oracle technology already secures tens of billions of dollars in value for industry-leading projects in DeFi, NFTs, and other major smart contract markets, making it a no-brainer that we are thrilled to bring to our community.

Why DFS Needs Oracles

A smart contract is a tamper-proof program running on the blockchain. The program’s code will execute deterministically based on the inputs it receives, wherein the inputs interact with the contract’s hard-coded logic to produce outputs.

Oracles are a service that enables external data from the real world (API) to be inputted into blockchains so it can be consumed by a smart contract. For example, oracles allow DeFi applications to access real-time price feeds on digital assets and gaming applications to obtain truly fair random numbers.

Unfortunately, compromised smart contracts have been commonplace due to faulty oracles supplying incorrect or manipulated inputs. Most notably, flash-loans have been used to manipulate price data on exchanges, centralized oracles open up central points of failure in data retrieval and/or data sourcing, and on-chain randomness solutions like block hashes have been gamed by miners.

Chainlink overcomes these problems as the undisputed leader in decentralized oracle solutions. The team at DFS couldn’t be more thrilled to implement Chainlink to better serve and protect our community from potential exploits as well as enhance the platform’s capabilities.

This integration swings the door of opportunity wide open for future implementation of new features; keep reading to find out exactly how this benefits all DFS users in the future!

Understanding Chainlink VRF

Chainlink’s VRF (Verifiable Random Function) is a provably fair and verifiable random number generator (RNG) purpose-built for smart contracts. Chainlink VRF allows smart contracts to access randomness in a manner that is transparent, secure, and unbiased to all players. Chainlink VRF will be applied in nearly all future implementations of new features in the ecosystem that require randomness. The basic workflow includes:

For every new request for randomness, Chainlink VRF generates a random number and cryptographic proof of how that number was determined.
The DFS smart contract will only accept the random number if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof.
The random number is used to produce a truly random outcome on the DFS platform.

Chainlink VRF ensures that oracle operators, miners, users, and even DFSocial developers cannot manipulate the results for personal gain, or any other reason, period.

DFSocial Will Leverage Chainlink VRF To:

Vastly Improve Security/Stability — To prevent randomness from being tampered with by miners or RNG data providers for financial gain or other nefarious reasons. Chainlink VRF provides critical security and transparency to the RNG process, ensuring users can verify that all outcomes produced by it happened exactly as intended.
Generate Random NFTs — Randomly assigning NFTs their rarity, benefits, and appearance, among other details to ensure each is authentic and unique.
Giveaways — Giveaways (that will randomly select winners in the community) can be trusted to be 100% randomized, secured, and free from foul play.
Mystery Boxes — The selection of prizes assigned to the Mystery Boxes (that will contain random rewards such as NFTs, free access to tournaments, merchandising, extra rewards, $bDFSocial tokens, etc.) can be 100% randomized, secured, and free from foul play.
Random Draws — A random draw system will be integrated into the platform, and the winner selection process will be 100% randomized, secured, and free from foul play.

As the DFSocial team explores other possible ideas to reward our community, we’re all extremely excited to roll up our sleeves and get to work! The possibilities are nearly endless.

This added flexibility moving forward will result in increased efficiency by team members, as repetitive and laborious tasks can now be automated with the implementation of Chainlink VRF. Ultimately, we can now focus our efforts on more pressing tasks that require immediate attention.

The only thing a user needs to worry about now is remembering the time and date of the next tournament!

“Integrating Chainlink into the DFS Gaming platform was imperative in the growth of our user base and the security it provides when computing and delivering random numbers. Chainlink’s technology will ensure that all DFSocial smart contracts are as secure and reliable as possible while also allowing for the evolution of our rewards systems to develop efficiently.”
- Founder of DFSocial, Ibay Amor

A Brighter Future

The team couldn’t be happier with all the recent additions and improvements to the platform — and this one takes the cake as this will open up more possibilities than we can fathom at this point. Once again, we’d like to thank Chainlink and our community for their support. The future is bright, and we’re so excited to roll up our sleeves and put our thinking caps on to cook up some more magic for our loyal and deserving community.

Game on!
