Ethereum, which holds the title of the largest blockchain of smart contracts, has faced the problem of scalability.  As more users join Ethereum, the network becomes more expensive and slower.  In order to solve Ethereum's scalability problem, solutions have been proposed as alternatives to Ethereum.  In fact, the Ethereum ecosystem has designed and launched layer 2 solutions to solve its scalability problem.  In the meantime, the Optimism network is considered one of the most significant Ethereum layer 2 scaling solutions.  This solution is provided by a technology called Optimistic Rollups (Optimistic Rollups), which puts a large amount of transaction data into processable categories.
