That's the main difference of the lightning network. It's a secondary later, ultimately backed by the Bitcoin ledger, but is capable of performing many transactions that are all backed by a single transaction on the primary ledger. This drops transaction fees by a massive amount, and allows for much quicker transactions. Edit to add: I think Lightening is a really interesting tech, and I'm really curious to see how it handles scaling out in the real world. All that said, I think it's far too early to say how effective lighting will actually be for storefronts like Steam. The promise is that it will help, but we have to see if that promise bears out in the real world.
