How does the commit-reveal pattern prevent cheating?

The pattern hides player moves behind a hash commitment. Players must submit their hash before anyone reveals, ensuring no player can see their opponent's move before choosing their own.

What role does GF(3) play in the winner determination?

GF(3) refers to Galois Field of order 3. It provides a mathematical formula (move1 - move2 + 3) % 3 that efficiently determines if the result is a draw, a win for player one, or a win for player two.

How are game timeouts handled?

The contract includes logic to handle players who fail to commit or reveal within a 5-minute window, allowing the honest player to claim a forfeit and recover funds.

Can I deploy this to Aptos mainnet?

Yes, while the examples provided use testnet, the Move code and architecture are designed for deployment on the Aptos blockchain after proper testing and initialization.

Implements a provably fair, commit-reveal Rock-Paper-Scissors game on the Aptos blockchain using Move smart contracts.

Move RPS Game is a specialized skill designed for developers building decentralized PvP applications on the Aptos blockchain. It provides a robust implementation of the commit-reveal pattern to ensure move privacy and prevent front-running, utilizing modular arithmetic (GF(3)) for elegant winner determination. By incorporating ACSet-informed design and a strict state machine architecture, this skill helps developers create secure, fair, and timeout-protected gaming experiences in the Move language.
