Optimism’s Optimistic Virtual Machine (OVM) potentially represents a monumental leap forward for Layer 2 solutions. In this article, we’ll take a closer look at what Layer 2 solutions are, why they’re so important, and why Optimism and their Optimistic Virtual Machine could constitute such an important breakthrough for Ethereum. In essence, the OVM environment theoretically allows developers to move their smart contracts onto this quicker and less expensive solution with only a few lines of code.
Scalability has been an issue related to the Ethereum blockchain for years, so the next time you hear terms like Sidechains, Plasma, Channels, or Rollups, you’ll no longer have to wonder what they mean. These are all proposed solutions to help Ethereum scale. Moreover, so-called Layer-2 solutions are widely seen as potentially holding the keys to helping Ethereum to scale and reduce Ethereum gas fees.
