Optimism (OP) is the second level of Ethereum scalability based on Rollup optimization technology. This technology allows you to increase the performance of the blockchain, reduce the cost of transactions and increase its scalability. The main idea of Optimism is to reduce the number of transactions on the Ethereum blockchain by transferring them to the second level (Rollup).
Rollup is a platform that groups several transactions into one and sends only the total result to the main Ethereum network. This allows you to significantly increase the network bandwidth and reduce the cost of transactions.Optimism uses Ethereum Virtual Machine (EVM) and allows you to run all the same smart contracts as on the main Ethereum network.
This allows you to create decentralized applications (dApps) based on Optimism without the need to change the code of smart contracts.The main advantage of Optimism is to increase the performance of the Ethereum blockchain and reduce gas costs (transaction fees).
Also, thanks to the scaling of the second level, Optimism can significantly reduce the waiting time for transaction confirmation.In addition, Optimism develops a number of tools to improve the performance and scalability of smart contracts, such as an optimized set of tools for developing, managing transactions and testing smart contracts.
There are many projects and companies using Optimism technology to create scalable and productive decentralized applications on Ethereum.
The Optimism team is actively working to further improve Rollup technology and attract new users and developers. In general, Optimism represents an important step in the development of blockchain technologies and decentralized applications.
Its application can increase the scalability of Ethereum and make it more accessible and efficient for users and developers.
