How to run

Option 1: Build react app and run it with flask

# Run flask app on port 5000
cd frontend
npm run build
cd ..
cd backend
flask run

Option 2: Run react app and flask separately

Run the following commands in two separate terminals:

# Run react app on port 3000
cd frontend

cd backend
flask run

Blockchain

Execute these commands from inside the frontend/ folder:

npx hardhat node --port 8546

npx hardhat node --port 8545

Starts the blockchain nodes (8546 for public one, 8545 for private one). It always resets the chains.

npx hardhat run scripts/deploy.ts --network localhost

Deploys the contracts located in contracts/ on the private chain. The script needs to get updated when creating new contracts.

node scripts/rollup.js &

Runs the rollup script in the background (& for Linux). It will shut down automatically when the connection to the private chain ends. Rollups are logged in the scripts/rollup_logs.log file.
