Imagine a fully on-chain poker game where you can’t see your opponents’ cards, or a strategy game with truly concealed player states. This isn’t science fiction; it is the potential unlocked by COTI’s multi-party privacy layer for Web3 gaming.
Currently, on-chain games face a fundamental limitation, full transparency. Every move, card, or resource is visible to everyone on the blockchain. While this ensures fairness, it makes it impossible to build true ‘Fog of War’ games that depend on secrecy or private player states. COTI is changing this narrative by introducing Programmable Privacy to the gaming world.
Breaking the Transparency Barrier with Garbled Circuits
COTI’s Garbled Circuits technology offers a breakthrough solution. As the fastest and lightest privacy layer on Ethereum, COTI enables computations to take place privately on-chain, up to 3,000x faster and 250x lighter than alternative solutions.
This innovation allows developers to maintain transparency for outcomes while keeping sensitive logic or inputs hidden. Because COTI is fully EVM-compatible through its ‘GC Layer’, developers can build privacy-preserving games using familiar Web3 game development stacks, simply adding privacy parameters where needed. COTI unlocks private strategy, in-game economies and even AI agent character play, opening the door to innovation.
From Theory to Reality: Santa’s Vibe Coding Challenge
To demonstrate the power of COTI, we recently launched Santa’s Vibe Workshop, a challenge that invited the community to “vibe code” Christmas-themed games using AI prompts and integrate private tokens on the COTI network. A simple challenge designed to demonstrate how easily privacy can be woven into gameplay. The community responded with incredible creativity, proving that the barrier to entry for on-chain privacy has never been lower. By using COTI’s prompt packs and AI tools, even non-developers were able to build sophisticated, privacy-enhanced games
Community Outcomes: Privacy in Action
The Santa’s Vibe Challenge produced several examples of how COTI’s infrastructure can be applied to gaming:
Christmas Snake Game (by @kagurakagura2_8): A festive twist on the classic snake game, demonstrating how private tokens can be integrated into simple, addictive gameplay.
Santa’s Onchain Race (by @CryptoExpressX): A fully on-chain 3-lane highway racer where players collect gifts and claim rewards privately using COTI to level up their cars.
The Grinch Won (by @OdinBor57812303): A strategy-based game where presents remain safe and private on-chain, even when the Grinch wins, showcasing secure asset management.
Santa Fruit (by @AiceKing27): A “fruit ninja” style game where all transactions and point multipliers are kept private, ensuring a fair and confidential competitive environment.
Santa Shooter (by @wahyu_miftakya): A fast-paced shooter that incorporates a private power-up shop, allowing players to upgrade their abilities without revealing their strategy to others.
Snow Breaker (by @PrasetyaIday): A Christmas-themed “brick breaker” style game where players bounce snowballs to destroy obstacles, featuring private token rewards and updated gameplay mechanics. •
Santa Tetris (by @marianalouca88): A Christmas-themed brick stacking game in the style of Tetris with private token rewards.
These examples highlight three core pillars of COTI’s gaming utility: Private In-Game Economies, Hidden Game Logic, and Accessible Innovation.
Expanding COTI’s Role in Web3
While COTI’s enterprise-grade focus makes it an ideal choice for DeFi, Payments, RWAs, and AI, gaming represents a natural expansion that showcases the flexibility of Garbled Circuits and the ability for privacy infrastructure to influence a new wave of Web3 gaming and blockchain entertainment. COTI provides the resources needed to build the fully on-chain games that weren’t possible before. The future of gaming is private , and with COTI, trust and secrecy coexist seamlessly.
Summary COTI is revolutionizing Web3 gaming by enabling privacy through Garbled Circuits. From the community-led Santa Vibe Workshop to complex on-chain strategy games, COTI provides the speed and privacy needed for the next generation of decentralized entertainment.
