Good question @ervin-lemark ! ERC20 would fall under this new "Token Economy." ERC20 is simply a standard to be adhered to by the "tokens" created on or for the Ethereum Blockchain.

Yes, that's what I was implying :)

ERC20 tokens are tokens^2 :)

They are easy to create, don't require a separate blockchain, ...

My guess is that we will see many more of this kind of tokens in the future.
