Ethereum

Ethereum's Layer 2 solutions enhance the network's scalability by processing transactions off the main blockchain, reducing congestion and fees. Technologies like rollups, sidechains, and state channels enable faster, cheaper transactions while maintaining security through Ethereum's mainnet. Popular implementations include Optimistic Rollups and zk-Rollups, offering significant improvements in throughput. These innovations are crucial for Ethereum's growth, supporting decentralized applications and DeFi projects by addressing scalability challenges and improving user experience.
