Every time a block fills, a fee spike hurts users. Layer‑2 roll‑ups and sidechains solve this by moving most work off‑chain while still anchoring to the main chain. They cut costs, boost throughput, and keep security. That’s why dApps can offer instant swaps, NFT minting, and gaming at scale. The real hurdle now is making the experience as friction‑less as fiat—only then will mass adoption truly take off.
