Optimistic Rollup (OR)

    An Optimistic Rollup (OR) is a type of Layer-2 scaling solution that runs on top of the Ethereum network. Optimistic Rollups are similar to the Plasma scaling implementations used for Ethereum, but unlike Plasma, Optimistic Rollups allow the operation of an Ethereum Virtual Machine (EVM) compatible Optimistic Virtual Machine (OVM), allowing for increased functionalities for Optimistic Rollup technology. The name ‘Optimistic Rollup’ comes from the process of implementing transaction bundles that are ‘rolled up,’ allowing network transaction speeds to increase exponentially.
