Kaia and Proof of Play

The blockchain gaming landscape demands trust, fairness, and transparency. Players need confidence that game mechanics operate without manipulation, while developers require robust infrastructure to build engaging onchain experiences. Kaia’s partnership with Proof of Play addresses these needs by integrating proven gaming infrastructure directly into the Kaia ecosystem.

About Proof of Play

Proof of Play is a blockchain gaming and infrastructure company that developed Pirate Nation, widely regarded as a top onchain game. This game served as a proving ground for Proof of Play’s unique infrastructure stack and tools, which are now accessible to third-party developers for both onchain and offchain applications.

Co-founded by Amitt Mahajan, a co-creator of FarmVille, Proof of Play successfully secured a significant seed round from investors, including a16z and Greenoaks Capital. Proof of Play technology reports processing over 1 billion transactions across its proprietary blockchains, Apex and Boss, and reportedly captured a notable share of Ethereum’s daily compute at peak.

Proof of Play is expanding its technology to integrate with other prominent blockchains, offering a suite of onchain services. These include a Verified Random Number Generator (vRNG) for rapid and scalable random number generation, Mirroring for cross-chain decentralized applications, Gasless Transactions & Signless dApp Experience to streamline user interaction, Gasless Relaying to eliminate user gas fees, and Marketplace APIs for in-game trades. Additionally, Proof of Play provides a NoSQL Database for comprehensive onchain application development.

Now Proof of Play is expanding to other networks and distribution channels. Proof of Play is supporting live-ops gaming on Abstract with the Proof of Play Arcade. They are also developing mobile native app “Shiba Story Go!” showcasing the Marketplace API product supporting real money trades settled onchain with the crypto component completely abstracted away from users. All of the company verticals are aimed at positive cash flow and revenue generation to support the $PIRATE token, available on major exchanges.

Verified RNG (vRNG) on Kaia

To bring fair play and trust to the onchain economy — mirroring what Proof of Play achieved in its own apps — the company has launched its Verified RNG (vRNG) for public use. The vRNG follows key principles:

• Unpredictable
• Unbiasable
• Transparent
• Verifiable
• Fast

The Proof of Play vRNG is a cryptographic tool that confirms random events are generated fairly, without tampering, and stores outcomes onchain for permanent transparency. It delivers results in seconds.

As the largest decentralized randomness service by request volume, it has managed over 100 million calls at scale. It’s integrated into leading apps and games on more than 16 Ethereum-compatible chains, plus EVM testnets, meeting high standards for onchain fairness.

Products using Proof of Play vRNG give communities reliable, tamper-proof randomness. Users gain confidence in fair results when they see the “Powered by Proof of Play” seal.

On Kaia, vRNG supports game mechanics like loot drops, minting, and procedural generation, leveraging Kaia’s efficient consensus and low fees for real-time applications. Developers can request random numbers by calling vRNG functions within their smart contracts deployed on Kaia, ensuring verifiable outcomes in high-volume scenarios.

Proof of Play Marketplace API

Beyond vRNG, Proof of Play’s Marketplace API represents a potential future integration that could expand trading capabilities for Kaia developers. The API enables developers to build in-game marketplaces where items can be traded using USDT on Kaia, while the underlying assets don’t necessarily need to be NFTs — they can remain in traditional databases. This hybrid approach allows developers to leverage blockchain’s transparency for payments while maintaining flexibility in how they manage game assets. This aligns with Kaia’s focus on stablecoin adoption and provides a familiar USD-denominated trading experience for users.

For Kaia developers, this means the ability to:

• Create marketplace functionality with USDT as the settlement layer
• Potentially generate marketplace fees from peer-to-peer trades
• Offer users familiar USD-based pricing while leveraging Kaia’s efficient stablecoin infrastructure

The system is designed to embed directly into existing applications, making it accessible for teams building games, e-commerce dApps, or other applications where user-to-user trading could enhance engagement and monetization.

While the vRNG is the first tool available from this partnership, the vision for the Marketplace API integration highlights the long-term potential for bringing practical, revenue-generating solutions to developers building on Kaia.

Getting Started with vRNG on Kaia

Kaia developers interested in integrating Proof of Play vRNG can begin immediately. The service requires registration during early access, with approval available through the official form or direct contact with the Kaia team.

The integration process involves deploying smart contracts that implement the vRNG callback interface, registering contract addresses with the service, and handling random number requests through standard Solidity function calls.

Comprehensive documentation, including contract interfaces, usage examples, and verification procedures, is available in the vRNG Integration Guide.
