Based rollup proponents: Ethereum validators can’t handle high transaction demand or have high hardware resource requirements because it would force hardware upgrades, which hurts decentralisation. So instead, we’ll just have this same set of Ethereum validators run an additional piece of software that requires the very hardware upgrades we wanted them to avoid, but we call it a based rollup. This way, they can somehow totally handle the exact workload we claimed was too excessive for them to do on Ethereum.
