OP Mainnet is a Layer 2 platform for Ethereum.
OP Mainnet is, in a nutshell, an application inside of Ethereum that executes transactions more efficiently than Ethereum itself. It's based on the concept of the Optimistic Rollup, a construction that allows us to "optimistically" publish transaction results without actually executing those transactions on Ethereum (most of the time). OP Mainnet makes transactions cheaper, faster, and smarter.
