This is a demonstration of how to use publicly verifiable on-chain randomness withink ink! smart contracts. It is a smart contract and associated user interface that allows players to engage in a p2p, competitive rock-paper-scissors game. In this version of RPS, both players play against future randomness, trying to beat it. It is essentially a lottery where players can guess either 0, 1, or 2.
Locally running the project first requires that you run a local Ideal node. You can get started by running the docker image:
docker pull ideallabs/ideal-node-template
docker run ideallabs/ideal-node-template --tmp --dev --alice or use the template repo: https://github.com/ideal-lab5/ideal-node-template
Install the cargo contract CLI:
cargo install --force --locked cargo-contract- Build the contract
run :
cd contract/rps
cargo contract build- deploy the contracts
Assuming you have a node running on port 9945 (default is 9944), deploy the contract with the cargo contract CLI. From the root directory, run:
cargo contract instantiate ./target/ink/rps.contract --constructor new --args 70 --suri //Bob --url ws://127.0.0.1:9945 -x- configure the UI
Ensure the the constants in App.js use the correct contract address and host.
- run the UI
npm i
npm run start
