Ethereum is slow. Let's accept this fact. Most of the Ethereum updates are good on layer 2. Most of the switching of funds happen on L2 layers. So Ethereum team decided to move from proof of work to proof of stake. But the update and movement was so slow that despite the move the chain continues to lag in features, speed, performance and updates. 

So the people like Justin drake wants Ethereum to update it's core and focus on beam chain update. So this update would simplify a lot of things about the ethereum. And things would take off much better too. There is an explainer video of this beam chain update. 

Focus is on the upgrade of the Ethereum's consensus layer. And this would make the L2 operations even more easier too. So this update has to be made in order to keep up with the chains in the modern times. And this would also be able to keep up with the new blockchain changes in the market. 

You can learn more about this upgrade in the video below. 

In short, this layer would help move the Ethereum in the modern direction and address some of the issues on the chain. We are going to see updates of the Ethereum chain that would add some value on the chain too. Lot of interesting things being launched. So let's wait for them to come out :)
