#Layer2 Technology: The Future of Ethereum Scalability
Layer 2 technology significantly enhances throughput and reduces costs by processing transactions outside the Ethereum main chain. The main solutions include Rollups (such as Optimistic and ZK-Rollups), state channels, and sidechains, which achieve efficient scaling while maintaining security. Rollups compress transaction data and anchor it to the mainnet, balancing decentralization and low costs. As the ecosystem develops, #Layer2 will become a key infrastructure for the large-scale deployment of DApps, driving blockchain towards mainstream applications.
