# Layer 2 (L2) On Layer 2 networks, transaction fees will be drastically reduced by packing multiple off-chain transactions into a single L1 transaction, making it easier for everyone to participate in Ethereum. The L2 network blockchain settles transactions on the Ethereum mainnet, enabling users to benefit from the security of the Ethereum network. As transactions per second (TPS) increases, transaction fees decrease, and new technologies develop, new applications will emerge within the ecology and boost user experience. The Ethereum ecosystem stays steadfast in supporting L2 networks because L2 network scaling is the only way to solve the scalability trilemma while maintaining decentralization and security. Zecrey is an outstanding Layer 2 privacy protocol utilizing cutting-edge zk-Rollup technology. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
