Optimism is a layer 2 scaling solution for Ethereum that uses optimistic rollups to increase transaction throughput while decreasing fees and latency. The goal of this protocol is to give users a smooth experience while keeping the Ethereum network safe and decentralized. In this essay, we’ll talk about how the Optimism protocol works from a technical point of view and how it meets its goals.
Optimistic Rollups
Optimistic rollups are a layer 2 scaling solution that lets Ethereum handle more transactions by combining them into a single transaction that is then sent to the Ethereum network. This is called “rolling up.” A smart contract that runs on the Ethereum network checks the rollup to make sure that it follows the rules of the network. The process of validating optimistic rollups is what makes them safe.The Optimism protocol gives Ethereum the ability to grow by using optimistic rollups. In optimistic rollups, transactions are first verified off-chain. Then, all of the transactions are put into a single rollup and sent to the Ethereum network. This lets Ethereum handle more transactions per second while keeping the network safe and not relying on any one person or group.
Fraud Proofs
Fraud proofs are used to check the rollup transactions to make sure the Optimism protocol is safe. Fraud proofs are used to find transactions that aren’t valid and to make sure that the rollup follows the rules of the Ethereum network. If an invalid transaction is found, the fraud proof is sent to the Ethereum network and the transaction is rolled back. This makes sure that the Ethereum network’s security and integrity are not broken.The Optimism protocol’s way of stopping fraud is based on the idea of the Optimistic Virtual Machine (OVM). The OVM is a virtual machine that simulates the Ethereum network and runs off-chain. It is used to check if a transaction is valid before it is sent to the rollup. If a transaction is found to be invalid, a fraud proof is made and sent to the Ethereum network. The fraud proof is then used to roll back the transaction and keep it from being added to the rollup.
Optimistic Virtual Machine (OVM)
A key part of the Optimism protocol is the Optimistic Virtual Machine (OVM). It is a virtual machine that simulates the Ethereum network and runs off-chain. Before being sent to the rollup, transactions are checked by the OVM. This makes it possible for the Optimism protocol to provide scalability while keeping the Ethereum network safe and not centralized.The OVM is made to work with the Ethereum Virtual Machine (EVM) (EVM). This means that smart contracts written for the EVM can be run on the OVM without any changes. This makes it easy for developers to put their apps on the Optimism protocol.The OVM makes it easy to do transactions off-chain without using a lot of gas. Gas is the fee that miners get paid to do transactions on the Ethereum network. By running transactions outside of the blockchain, the Optimism protocol lowers the gas fees users have to pay, making it cheaper to use.
Conclusion
The Optimism protocol is a layer 2 scaling solution for Ethereum. It uses optimistic rollups to make scaling possible while keeping the Ethereum network secure and decentralised. Using fraud proofs and the Optimistic Virtual Machine (OVM) makes sure that rollup transactions are valid and that the security and integrity of the Ethereum network are not compromised.The Optimism protocol gives users a way to do transactions off-chain that uses less gas. This lowers the amount of gas fees they have to pay. This makes it less expensive to use and makes it easier for people to use.
