This is a demonstration of how ERC721 tokens can be used to represent software licenses.
You buy a token, then authenticate with a server by cryptographically verifying that you own the address that owns the token.
- Node.js v8.9.4
- Ganache (or some other local test ethereum node)
- Infura API account and ethereum account loaded with some ETH (we're using Ropsten)
- The following environment variables set in a .env file in /app:
- MNEMONIC (seed mnemonic of an account where first derived address has positive balance)
- INFURA_API (infura eth node api key)
Update contract_address and server_address in app/src/index.js and app/server.js
Run the server:
cd app npm install npm start
Start Ganache or another ethereum node - server.js expects it to be available on port 7454
In a browser go to: http://localhost:3001
Connect to Ganache's network in metamask and import a user from Ganache so that you have ether to spend.
