0G Builder Spotlight: How Kult Games Is Building the Ultimate Gaming Browser

0G’s AI-focused infrastructure is designed to meet the high-performance, data-intensive demands of next-gen games. Its modular architecture combines execution, storage, data availability, and compute into a unified stack, unlocking new opportunities across a vast array of onchain gaming ecosystems.

Kult Games is one of the first partners to show what this looks like in a live environment. Rather than building a single title, Kult is creating a unified gaming browser where identity, inventory, and progression persist across multiple games, all running natively on 0G.

Their first release, ZeroGPool, provides a live example of how this infrastructure behaves under real conditions. This release includes:

• <100ms execution for in-game actions processed directly on 0G Chain
• Sub-120ms reads from 0G Storage that load full player profiles instantly
• 5× faster DA streaming, enabling transparent match validation and anti-cheat
• A 65–70% cheaper backend stack than AWS that is infinitely more composable

This marks a new era for web3 gaming, proving that real-time entertainment can operate onchain at scale. And it works because Kult built its entire ecosystem on 0G’s unified, high-performance onchain stack.

What Is Kult Games?

Kult Games is developing a unified gaming browser built on 0G. The objective is to create a cohesive environment where multiple titles share the same identity system, inventory, and long-term progression model. In this structure, a player does not restart when switching games. Instead, achievements, items, preferences, and history remain consistent across the entire ecosystem.

ZeroGPool, Kult’s first released title, serves as a practical demonstration of this vision. It provides early access to the core mechanics that the browser will eventually standardize. These include:

• Real-time competitive gameplay that runs fully onchainin with sub-100 millisecond execution on 0G Chain
• A persistent identity stored on 0G Storage that loads within roughly 120 milliseconds
• Inventory and rewards that remain accessible across future Kult titles
• Publicly verifiable match data streamed through 0G Data Availability
• Early exposure to upcoming cross-game systems such as AI-driven matchmaking and intelligent NFTs

The browser approach treats each game as part of a larger system rather than as an isolated release. The underlying infrastructure must therefore support fast reads, reliable execution, and a high volume of persistent data. These requirements shaped Kult’s evaluation of different blockchains and ultimately led the team to adopt 0G as the foundation for the entire platform.

“0G’s modular infrastructure is the bedrock of our ecosystem. It lets us unify multiple games into one persistent universe and unlock real-time PvP, AI systems, and a cross-game inventory that simply wasn’t possible before.” — Karn Chakerverty, CEO of Kult Games

Why Kult Chose 0G

Before 0G, Kult experimented with multiple chains and off-chain systems. Each had their verifying strengths, but none offered a unified environment capable of supporting real-time gameplay, large-scale storage, and cross-game identity in a single stack

These limitations forced Kult to rely on AWS S3 for storage, Firebase for identity and leaderboards, and custom servers for progression data. The stack became fragmented, and player information had to be recreated for each game. Cross-game progression, unified identity, and shared inventory simply were not achievable in a clean or cost-effective way.

Kult selected 0G because it addressed all of these constraints directly:

• Unified infrastructure. 0G combined chain execution, decentralized storage, and data availability, allowing Kult to retire AWS, Firebase, and custom metadata servers.
• Real-time performance. Transaction times under 100 milliseconds made it realistic to process competitive gameplay directly onchainin rather than offchain.
• Fast and affordable storage. Read and write times under 120 milliseconds and roughly 65-70% lower cost than AWS enabled scalable identity and progression storage.
• High-performance DA. 0G DA supported continuous streaming of gameplay packets and replay data, which allowed for transparent rankings and stronger anti-cheat systems.
• Simplified development. A single integrated environment reduced engineering overhead and helped the team ship ZeroGPool in a matter of weeks.
• Support for AI-native features. The upcoming compute layer and ERC 7857 intelligent asset standard aligned with Kult’s plans for AI matchmaking, adaptive NPCs, and evolving player avatars.

For Kult, 0G was the first environment capable of supporting the architectural requirements of a unified gaming browser. It allowed the team to consolidate their stack and build features that had been impractical or impossible with previous solutions.

“Kult Games chose 0G because it is the only infrastructure capable of running real-time, AI-powered onchain games at scale with modular compute, fast DA, and storage built for gaming rather than just tokens.” — Karn Chakerverty, CEO of Kult Games

How Kult Games Integrated 0G

Kult makes use of several major components of the 0G stack, with plans for additional integrations as 0G comes fully live on mainnet. Their objective was to consolidate gameplay logic, identity data, and progression systems into a single environment rather than relying on multiple external services.

The team adopted these layers gradually, beginning with chain execution for real-time gameplay and then extending into storage, DA, and compute as the scope of their offerings expands. 

Broadly speaking, 0G’s modular offerings unlock the following for Kult Games:

0G Chain

• All player actions, match state updates, and reward logic are executed directly onchain.
• Execution times under 100 milliseconds support real-time competitive gameplay.
• Provides the shared identity and progression contracts that all Kult titles interact with.
