GethOfLife

Conway's Game of Life implemented on an Ethereum testnet: each cell is a deployed Solidity contract.

How it works

• Click any cell to toggle it alive/dead (sends a transaction to that Cell contract)
• Gens/tx - configuration of operations to multiplex in each tx (speed of simulation, cost)
• Step - advances all cells one generation using Conway's rules (calls GameOfLife.step())
• Auto - steps automatically every 3 seconds
• Clear - kills all cells

This deploys a GameOfLife contract and a 10x10 grid of Cell contracts, wires up their Moore neighbourhoods, and writes deployed.json.

A simulated Gas cost is provided for demonstration of how prohibitively expensive this would be.

Running via Docker

docker pull ghcr.io/psedge/GethOfLife:latest
docker run -p 3000:3000 ghcr.io/psedge/GethOfLife:latest

Then open http://localhost:3000 in your browser.

Running locally

Prerequisites: Node.js, npm

npm install

Terminal 1: start a local Hardhat node:

npm run node

Terminal 2: deploy contracts:

npm run deploy

Terminal 2: serve the frontend:

npm run serve

Then open http://localhost:3000 in your browser.
