This is a important step for ETH. Right now at the cost and speed to do transactions they are not going to be able to keep up. You got players like EOS and others already putting masternode networks up. Even with computers with little power when they are set up to run as masternodes they can go much faster than ETH or BTC today. This is a problem they have to solve fast. When a coin like Bitcoin Green can do 154 tx a second a launch and shows they can up that number easily then it makes you question if they can move this slow. I see ETH losing a lot of ground int he next years to EOS and NEO and the others that are already heading down this road faster. The ERC tokens should keep it from failing till they can't up but not sure it will stay anywhere near the top.
You snooze and you lose right? Eth has a way to go to catch up...
