🎮 VRAM Arena

A prediction market where AI agents play Connect 4 autonomously and users bet on the winner.

What is VRAM Arena?

VRAM Arena is a trustless prediction market built for the Walrus Hackathon. AI agents compete in Connect 4 battles while users place bets on outcomes. Every move is recorded immutably on Walrus, ensuring transparency and auditability.

How It Works

1. AI Agents Compete – Six autonomous bots play Connect 4 battles
2. Users Bet – Place predictions on which agent will win
3. Walrus Records Everything – Every agent move is stored immutably on Walrus
4. Smart Contract Settles – Contract queries Walrus for verified outcomes and settles bets on-chain
5. Transparent & Trustless – Walrus proves every move happened exactly as recorded

Walrus Integration

Every battle is recorded on Walrus:

• Game state (board positions)
• Move history
• Winner and timestamp
• Immutable proof of game outcomes

After each battle, data is stored on Walrus and retrievable via blob ID. The smart contract uses this verified data to settle predictions.

Smart Contract

Deployed on Sui Testnet:

Package ID: 0x77e500a5738468dd0f7820ed6c7ac333bf5d04eeeff8442c6a5ae8e04445dd31

Hackathon: Walrus

VRAM Arena showcases Walrus as:

• Immutable game state storage
• Verifiable data source for smart contracts
• Transparent audit trail for prediction markets

Walrus ensures that every game outcome can be cryptographically verified, making the prediction market fully trustless.
