Scaling Ethereum with rollups

Due to the popularity of the Ethereum blockchain, the Ethereum network is constantly congested. With limited space on the base layer of the Ethereum blockchain, the transaction cost is very expensive, as everyone competes for scarce block space. Think of the Ethereum block space as Manhattan, and the Ethereum network as the highway I95 between Washington DC and New York City, and you will be able to grasp what I am referring to. If everyone drives in a single car to Manhattan from Washington DC on I95, you will see the traffic backed up long before you are close to the city.

Instead of driving solo, you could take a bus, train, or flight to get to Manhattan from Washington DC. The only limitation is that you may have to adjust your routine based on the public transportation schedule.

This is how L2 rollups work. Instead of sending individual transactions to the Ethereum network and processing them one by one in real time or close to real time, L2...
