Edit (Nov 2022): There have been breaking changes to NEAR integration since we built this demo; we're leaving this example up, but builders beware that we're not able to provide a whole lot of support for this example at the moment. Thank you for your understanding.
This README includes instructions to install and play RISC Zero Battleship on your own machine. For more information about RISC Zero Battleship, check out the tutorials at www.risczero.com. For questions, find us on Discord.
RISC Zero Battleship is a 2-player hidden information game implemented in Rust on the NEAR Network.
Players produce proofs of game-state and the result of their actions to enable two players to play fairly with no intermediaries.
- Web UI (client)
- Prover web service
- NEAR smart contract
Follow the instructions for Yew Project Setup.
Install the near-cli:
npm install -g near-cli
Create a NEAR account: https://wallet.testnet.near.org/create
Deploy the NEAR smart contract (optional)
cd contract
cargo build --release
near dev-deploy target/wasm32-unknown-unknown/release/battleship_contract.wasm
NOTE: If you deploy your own smart contract, you'll need to update the code to point to this new contract.
See: https://github.com/risc0/battleship-example/blob/main/web/client/near.js#L16
Launch the web service:
cargo run --bin battleship-web-server --release
Launch the web client:
cd web/client
trunk serve --open
cargo test
- There's an issue with the near javascript API that prevents adjusting the contract allowance during sign in or when the game starts. This limits each game to only a few moves regardless of how much NEAR the account had.
