Firework Games: Spark Era Trilogy Integrates with Chainlink VRF to Help Power Gaming Experience

We’re excited to announce that Firework Games: Spark Era Trilogy — the real metaverse world under the law of the “Dark Forest” — has integrated Chainlink Verifiable Random Function (VRF) on the Polygon mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to empower the loot box system and all in-game mechanics that require randomness. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can enjoy a fair “Play-To-Earn” gaming environment filled with elements of randomness.

Firework Games: Spark Era Trilogy is developed based on blockchain technology, combining both GameFi and NFT gaming assets as the core to advance the ecological construction of the game. In Firework Games: Spark Era Trilogy, players will play the role of star citizens of different races and battle against each other under the law of the “Dark Forest”. Players can build and upgrade interstellar warships in the game, conduct interstellar commercial trading, NFT empowered mineral collection, NFT card battles, planetary auctions, space station construction, real star exploration, strategic confrontation, and other activities.

In order to generate the items when opening loot boxes, matchmake players against one another, and assign planets (which you will know more about when the game is released) fairly, 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 Firework Games: Spark Era Trilogy smart contract will only accept the random number input if it has 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 Firework Games: Spark Era Trilogy is provably fair and was not tampered with by the oracle, outside entities, or the Firework Games: Spark Era Trilogy team.

We are excited about the integration with Chainlink VRF to help ensure that Firework Games: Spark Era Trilogy NFT distributions and in-game mechanics are executed in an unbiased and tamper-proof manner. This allows players to verify that Firework Games: Spark Era Trilogy uses a trustworthy process to distribute NFTs with real-world value. In the future, we hope to further integrate Chainlink products by applying Chainlink Keeper into our in-game store to enhance users’ experience through automation.

“I believe that Chainlink is one of the most famous projects in the crypto space. By using Chainlink VRF, our players will have more confidence in terms of fair gameplay and help our community grow exponentially” — Radesh, CEO of Firework Games.
