What is Optimism (OP)?
Optimism (OP) is a Layer-2 blockchain built on top of Ethereum. It enhances the scalability and efficiency of the Ethereum network by using optimistic rollups. These rollups bundle transactions off-chain, reducing the load on the Ethereum mainnet and lowering transaction fees.
Key Features of Optimism (OP)
Layer-2 Solution
Optimism is a Layer-2 scaling solution for Ethereum. It addresses slow transaction speeds and high fees by processing transactions off-chain before settling them on the mainnet.
Optimistic Rollups
Optimism employs optimistic rollups, assuming all transactions in a batch are valid by default. Validators monitor the network and can submit "fraud proofs" if they detect invalid transactions, challenging them on the Ethereum mainnet.
