Why Layer 2
Scaling Ethereum.
The Scaling Problem
Ethereum can only process a limited number of transactions per second. When demand surges, blocks fill up and gas fees spike.
Layer 2 (L2) solutions exist to scale throughput without sacrificing the security of the base chain.
Layer 1 vs Layer 2
Layer 1 (L1) is the base blockchain like Ethereum. Layer 2 is a separate system that processes transactions off the main chain but settles back to it.
- L1: maximum security, limited throughput
- L2: high throughput, inherits L1 security
