Why Are Layer-2 Solutions Being Developed to Address High Gas Fees?

Layer-2 solutions process transactions off the main blockchain (Layer 1) but still inherit its security. By bundling many transactions into a single Layer 1 proof, they significantly reduce the overall computational load and data required on the main chain.

This drastically lowers the per-transaction gas cost for users.
