Project overview and context

Overview

Hidden Warrior demonstrates how encrypted game logic can be applied to turn-based battles. Instead of exposing the rules directly in the client or on-chain, combat resolution and ability triggers are computed inside Arcium's Multi-Party Execution Environment (MXE). This makes the system tamper-resistant, unpredictable to cheaters, yet fair to honest players.

Problem definition and constraints

Challenge

In traditional RPGs, combat formulas are transparent: damage multipliers, cooldowns, and critical hit chances are easily reverse-engineered. The challenge was to build a battle system with hidden logic, where outcomes remain confidential while still following consistent, fair rules.

Approach and methodology

Solution

• Encrypted Combat Resolution: Player inputs sent into Arcium MPC clusters; outcomes revealed without exposing internal formulas.

• Confidential Abilities: Items and skills stored as NFTs with encrypted metadata on Solana, revealing hidden powers only when activated.

• Pixel RPG Layer: Built retro 16-bit style frontend in Next.js to make encrypted battles feel intuitive and familiar.

Technical decisions and architecture

Implementation

Key technical decisions and architectural choices

01.

Encrypted Battle Logic

Problem: Combat rules are usually easy to datamine and exploit

Solution: Battle formulas executed inside Arcium MXEs

Effect: Fair fights with hidden mechanics, impossible to reverse-engineer

02.

Pixel-Perfect UI

Problem: Needed modern accessibility while keeping SNES-style look

Solution: Custom React + Next.js interface styled for retro battle screens

Effect: Authentic retro feel, smooth user experience

03.

Solana Integration

Problem: Player assets needed hidden properties

Solution: Encrypted NFT attributes reveal unique abilities only in combat

Effect: Dynamic item discovery, long-term replay value
