SIX Network Integrates Chainlink VRF to Support K-POP NFTs Protocol

We’re excited to announce that SIX Network — a blockchain company that is a subsidiary of FSN (Future Stream Network Co., Ltd.), a top digital marketing company in KOSDAQ (Korean Securities Dealers Automated Quotations) — has integrated Chainlink Verifiable Random Function (VRF) on 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 determine which ID K-POP NFT purchasers receive upon mint. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users get stronger assurances that the NFTs issued from the minting protocol is fairly determined.

SIX Network launched T-ARA, the first NFT collection on Dingo x and one of the first K-POP NFTs launched in China and Southeast Asia. The T-ARA NFT collections consist of 5 tiers of rarity: Legendary (300), Epic (750), Rare (2,500), and Normal (5,000). Users are able to purchase the tier and card on their own.

In order to determine the IDs of the NFTs minted, we needed 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 NFT minting 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 T-ARA NFT collections are provably fair and cannot be tampered with by the oracle, outside entities, or the SIX Network team.

“Chainlink VRF was the obvious solution for helping ensure our minting algorithm is both fair and secure, giving users the chance to receive rare NFT IDs without paying full price. We wanted to make sure the process was fully transparent and unbiased, and Chainlink VRF helps us achieve that by allowing any user to independently verify the integrity of the randomness used.” — Vachara Aemavat, Co-CEO of SIX Network
