Hellobot Integrates Chainlink VRF to Help Power Random Mystery Box Reveal
We’re excited to announce that Hellobot — the first NFT project by thingsflow — has integrated Chainlink Verifiable Random Function (VRF) on Ethereum 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 randomize the contents of mystery boxes. Ultimately this creates a more exciting and transparent user experience, as NFT holders can have higher confidence that the contents of mystery boxes is determined using verifiable randomness.
Hellobot — originally a WEB2 entertainment AI chatbot with 2.8M cumulative users — is currently exclusively embedded into Naver Z’s ZEPETO, the largest metaverse platform in Korea with more than 20M monthly active users.
In order to help randomize the mystery box reveal process, 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 Hellobot 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 mystery box reveal is provably fair and was not tampered with by the oracle, outside entities, or the Hellobot team.
“We’re excited to leverage Chainlink VRF, a staple of the Web3 gaming and NFT space, to help power our mystery box reveal process. Proof of randomness is critical for establishing a high-integrity reveal process that gives our users high confidence that rewards are distributed fairly.” — Willy Lee, Co-Founder of Hellobot Universe

About Hellobot
Introducing Hellobot Universe, the first NFT collection from Korean WEB2 company, thingsflow. The founder team from DeFi/NFT firm, SOOHO.IO, has brought thingsflow’s character IP into the WEB3 world, revolutionizing the NFT scene with their smart contract tech support, community management, and more.
At Hellobot, the team believes in the core value of “Friendship” and aims to bring new quantitative and qualitative impact to the NFT scene through this value. Team prioritizes “Respect” towards their holders and partners, “NORI”, a Korean term that represents the engagement and entertainment of community members, and “Sustainability”, which enables their project to keep developing itself and its community.
Team implements their core values through advanced technological means, such as the mirroring method and verifiable random function, to show their respect towards their partners and holders. Additionally, their staking functionality with a point system rewards holders for their contributions, which further strengthens their bonds of friendship.
Looking to the future, the team has a comprehensive roadmap in place. Their first business model, “Metaverse Integration”, has already been achieved in the first metaverse, ZEPETO. Their core values will be realized through their sustainable business model. Their second business model, Real World Experiences, will soon upgrade to Real World Assets, paving the way for large-scale expansion.
Join them in the Hellobot Universe, where friendship is valued above all else, and NFTs are more than just digital assets, they’re a symbol of meaningful connections.
