Why Are Layer 2s Important for Ethereum?

[Ballie]

Layer 2 networks like Arbitrum, Optimism, and zkSync process transactions off-chain to reduce costs and improve Ethereum’s speed. They’ve become essential for scaling applications without overloading the main network.

These solutions highlight how innovation builds on top of existing systems, rather than replacing them. Even as Ethereum upgrades, Layer 2s may remain critical for handling demand. Do you see Layer 2s as a long-term solution or just a temporary bridge?
