Blockchain Scalability: What are Layer 2 Scaling Solutions
This reason has led to the creation of layer two scaling solutions that are much cheaper and faster when compared to the Ethereum network.
Layer 2 , like the example of the Linux distros, is built on top of layer 1. Layer 2s are tools and solutions that make the Ethereum network faster! To grossly oversimplify, they are built on Ethereum's layer 1 to leverage its security and existing functionalities like Smart Contracts.
Layer 2s primary focus is to scale the Ethereum network by offloading transactions from the Mainnet or Layer 1 while still harnessing Layer 1's robust security features.
You may be wondering, "why do we need a layer 2? why can't we directly scale layer 1" ; It is a bit complicated to explain why we can't scale layer one but let's get to the basics first!
The Ethereum network can only handle up to 15 transactions/second, which is very slow compared to other blockchains like Solana or even centralized applications like VISA, which handles over 50,000 transactions/second and 100,000 transactions/second, respectively.
