Where Fun Meets Fairness: Band VRF Enhances Zaar Chain's Decentralized Gaming Experience
We are excited to announce Band VRF integration with Zaar Chain, an EVM Minitia (L2) built on Initia, with Celestia as its foundation for data availability.
We are excited to announce Band VRF integration with Zaar Chain, an EVM Minitia (L2) built on Initia, with Celestia as its foundation for data availability. Band VRF (Verifiable Random Function) plays a crucial role in decentralized applications (dApps) by ensuring secure, verifiable randomness. On Initia, this integration adds an extra layer of fairness and transparency to applications.
This article will explain how Band VRF works on Initia, why it’s essential for decentralized ecosystems, explore its use cases—such as its role in ZaarChain—discuss how developers can participate, and highlight future opportunities for both Band VRF and the Initia ecosystem.
Why Band VRF on Zaar’s EVM Minitia network
Zaar recently announced Zaar Chain: The Fun Network, an EVM Minitia (L2) built on Initia, leveraging Celestia as its base for data availability. Zaar Chain is dedicated to creating an expansive network where crypto enthusiasts—especially those seeking fun-maximizing experiences—can engage in permissionless activities. This network promises to offer exciting, original games and consumer-oriented dApps that encourage users to "run wild."
Zaar Chain’s gaming applications will benefit immensely from Band VRF, providing the fairness and verifiability needed in randomized outcomes. This ensures that games on Zaar are secure and transparent. The synergy between Zaar's vision of becoming "The Fun Network" and Band Protocol’s mission to empower Web3 developers aligns perfectly, as both seek to foster a space where creativity and fun can thrive without barriers.
Band VRF on Zaar Chain
By incorporating Band VRF, Initia now supports creating decentralized applications that require verifiable randomness. This includes use cases across gaming, lotteries, NFTs, and beyond. The integration ensures trustless, transparent outcomes, contributing to the broader ecosystem of dApps on Initia.
The figure below demonstrates the high-level overview of how Band VRF works on the Zaar Chain in 12 steps.
1.) Request Random Data: The process begins on Zaar Chain where a dApp submits a request for random data to the VRF Provider Contract.
2.) Pick-Up Request: The Off-chain Resolver Bot picks up the randomness request from the VRF Provider Contract.
3.) Request Data on BandChain: The Off-chain Resolver Bot then submits this request to the VRF Oracle Script on the BandChain.
4.) Choose a Data Source Randomly: The VRF Oracle Script randomly selects one of the available VRF data sources to handle the request.
5.) Call External API: The selected VRF Data Source calls an external API to generate a random number.
6.) Generate VRF Result and Proof: The VRF Data Source generates a random number and cryptographic proof, which is sent back to the VRF Oracle Script.
7.) Verified VRF Result: The VRF Oracle Script verifies the result using the proof provided by the VRF Data Source.
8.) Pick-Up Merkle Proof: The verified VRF result is included in the BandChain state, and the Off-chain Resolver Bot picks up the Merkle Proof of this inclusion.
9.) Relay Merkle Proof: The Off-chain Resolver Bot relays the Merkle Proof to the VRF Provider Contract on the Zaar Chain.
10.) Submit Merkle Proof: The VRF Provider Contract submits the Merkle Proof to the Bridge Contract for validation.
11.) Validation: The Bridge Contract validates the Merkle Proof, ensuring that the VRF result was correctly generated and recorded on the BandChain.
12.) Return VRF Result: Finally, the validated VRF result is sent back from the Bridge Contract to the original dApp through the VRF Provider Contract, completing the process.
Use Case: Zaar Flip and Beyond!
Band VRF establishes its use cases on Zaar Original Games like Zaar Flip, offering a unique twist on the classic coin-flipping concept. Players can customize their odds by selecting up to 10 coins and deciding how many must land in their favor. The game also features Turbo Flip, allowing automatic flips of up to 100 rounds with a preset wager per flip. Additionally, users can take on the role of the house by staking INIT tokens and earning a share of the house edge, with a 48-hour cooldown on INIT withdrawals.
Band VRF unlocks several key elements in Zaar Flip:
- Transparency: Guarantee unbiased coin flip outcomes, ensuring users can trust that every flip is verifiable and secure.
- Fairness: Enhance the integrity of the Turbo Flip feature, ensuring fairness across multiple automated flips.
Unleash your Creativity on Initia

The future holds exciting opportunities as developers harness Band VRF to build more dynamic and fair Web3 applications, pushing the boundaries of decentralized innovation.
About Zaar
Zaar is building Zaar Chain: The Fun Network, as an EVM Minitia (L2) atop of Initia, with Celestia underneath, in pursuit of building an all-encompassing network where fellow degenerates can partake in fun maxxing.
At Zaar, we believe what Initia is building is more than just another smart contract platform, but an ecosystem designed to bridge liquidity from the ever-growing amount of ecosystems which inherently become more and more fragmented as they grow, into one grand interwoven layer.
