Hi,

I'm creating a new ERC20 token but I want to make it POS only. I found this tutorial that shows how to create ERC20 token:

https://steemit.com/ethereum/@maxnachamkin/how-to-create-your-own-ethereum-token-in-an-hour-erc20-verified

Is this all I need for a simple ERC20 token or I need add anything in this contract to make it POS?

Thank you in advance.
