Will optimistic rollup be the best solution for Ethereum scaling?

The Ethereum network's largest issue right now is scalability. Rollups and other scaling methods strive to improve the end user's overall experience. In a word, Ethereum is the most secure and decentralized blockchain that uses smart contracts in the world. However, because of the tremendous demand for Ethereum blockspace, the network becomes extremely costly for the typical user to use. When the network becomes overloaded, blockspace becomes scarce, forcing users to engage in a bidding war to have their transaction included in the next block.

But now we have rollups, rollups have two categories or two solutions: ZK rollup and optimistic rollup. For example, we have Metis which uses optimistic rollup with the enhanced layer 2 rollup solution to resolve the wait time through its Metis Virtual Machine (MVM), a virtual machine that is compatible with the Ethereum virtual machine. It separates the computing and storage of the Ethereum construct for layer 2. Thus, we have low gas fees on transactions and shorter wait times when withdrawing.

Optimistic rollups have been used by protocols such as Optimism and Arbitrum to improve the scalability of Ethereum. Arbitrum and Optimism have seen significant growth in the number of users and TVLs over the last few months. Metis, an Optimism fork, aims to provide another optimistic rollup framework with a different optimization between transaction throughput and decentralization.
