KAKA NFT World Integrates Chainlink VRF to Power a Fair and Transparent Gameplay

We’re excited to announce that KAKA NFT World, a competitive gaming ecosystem platform focusing on metaverse blockchain gaming, has integrated Chainlink Verifiable Random Function (VRF) on the Binance Smart Chain 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 results of all lucky draws that ensure the fairness of the gameplay in every event. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can have more confidence in the transparency and fairness of NFT airdrops and lucky draw events such as the Chosen One.

KAKA NFT World is a competitive gaming ecological platform focusing on the field of metaverse blockchain games. KAKA is creating a fun and valuable metaverse ecology with many well-known IP licenses and original IPs. By solving the strong centralization issue of traditional games and building a cross-chain bridge with the concept of decentralization, KAKA is dedicated to combining the application of NFT and DeFi in the ecosystem to create not only a prediction protocol perpendicular to the esports market prediction, but also an open, transparent, decentralized, and complete ecosystem project.

In order to help ensure the transparency and fairness of the Chosen One event, 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 a time-tested oracle network, 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. KAKA NFT World’s 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 Chosen One event is provably fair and was not tampered with by the oracle, outside entities, or the KAKA NFT World team.

Decentralization, fairness, openness, and transparency are the unchanging attributes of blockchain technology. They have a significant impact on the development of blockchain technology. Combining current development trends and forecasts for the future, KAKA may further apply Chainlink VRF technology to other functions of the KAKA project to help protect the essential rights of all users.

“KAKA integrated Chainlink VRF to provide users with a transparent gaming environment, which will amplify the innate effects of decentralization. Chainlink VRF can help information flow freely and efficiently in KAKA’s events. During operations, clear evidence of process integrity will be provided, which can effectively reduce trust costs and help users obtain a more trustworthy experience.” — Syed Jawad Haider, CMO of KAKA

About Chainlink

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
