Layer2 Solutions: The Future of Ethereum Scaling
The high Gas fee issue of Ethereum has spurred Layer2 scaling solutions such as Optimism, Arbitrum, and zkSync. They package transactions to the main chain using Rollup technology, improving speed and reducing costs. In 2023, the Layer2 ecosystem exploded, giving rise to numerous DeFi and NFT projects. In the future, modular blockchains (like Celestia) and Layer3 may further drive the scaling competition, but security remains the core consideration for users.
