Top 10 Layer 2 Scaling: Ethereum remains the backbone of Web3, powering decentralized finance, NFTs, and smart contract innovation. Yet, despite its success, the blockchain faces persistent scalability challenges. Gas fees often spike during high demand, transactions can be delayed, and throughput remains capped compared to global financial systems. These bottlenecks limit accessibility and prevent mainstream adoption.
The solution comes in the form of Layer 2 scaling technologies. By building on top of Ethereum, these solutions enable faster and cheaper transactions without compromising security. In 2025, they are no longer just experimental tools—they represent the infrastructure that will determine whether Ethereum can truly compete with traditional payment networks and power the next generation of decentralized applications.
