K-3 Kingdoms Integrates Chainlink VRF To Help Power Random and Fair NFT Distributions
We’re excited to announce that K-3 Kingdoms (K3K) — a blockchain-based game — has integrated Chainlink Verifiable Random Function (VRF) on BNB 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 help fairly distribute the Warrior and Legend Hero NFTs that we issue on our platform. Ultimately this creates a more exciting and transparent user experience, as users can verify that everyone has equal access to the rarest NFTs.
K3K is an SLG (simulated life game) that can be played on both mobile and PC across the globe. It aims to create a sustainable ecosystem centered around its Warrior and Legend Hero NFTs, and $K3K and $TKT tokens. K3K team members have a long and successful history across various game development and P2E projects.
In order to help make sure K-3K NFT distributions are fair, 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. The K-3 Kingdoms 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 distribution of K-3K NFTs is provably fair and was not tampered with by the oracle, outside entities, or the K-3K team.
Integrating Chainlink VRF for NFT distributions is just the beginning. We are planning to update content with various random elements in the game, and Chainlink VRF is expected to have a key role in this process. We are also communicating with various mainnets, and we are planning to expand to other chains where we plan to integrate Chainlink Automation and Chainlink Price Feeds.
“I think one of the biggest differences between Web2 and Web3 games is “fairness”. Because K3K requires randomness to help distribute our NFTs, we’re happy to help provide a fairer experience to K-3K users by underpinning the minting process with Chainlink VRF.” — Albert Lee, CEO of K-3K

About K-3 Kingdoms
“K3K will make you forget about E and focus on P.”
K3K has launched the NFT collection using the Asian-friendly Three Kingdoms IP to form a solid community, with the launch of a stable economic system and fun-oriented GameFi project.
After the game is released, players can develop their own territory in the lobby to build an economic system, and based on this, they can participate in two game modes, PvP, and MMO, to earn rewards based on their contribution.
K3K’s challenge to the global top-tier GameFi ecosystem will never stop.
