# Optimism Optimism is a second—level solution (Layer2, L2), which is designed to increase the speed and scalability of the Ethereum network. The Optimism blockchain uses the Optimistic Rollups technology, which reduces the cost of transaction fees tenfold compared to the first level (L1) of the Ethereum network and at the same time makes it easy to deploy any smart contracts and decentralized applications written in the Solidity language in the second level network. All CryptoDo modules and smart contracts are available for deployment on the Optimism network.
