Layer‑2 solutions—roll‑ups, state channels, sidechains—are turning blockchains from niche tech into everyday payment networks. By batching transactions off‑chain and anchoring them on‑chain, they slash fees and boost speed, letting billions use crypto for remittances, gaming, and DeFi. The real test is interoperability and developer tooling, but each L2 milestone brings us closer to mass adoption.
