Optimism’s strength lies in its developer-friendly environment, leveraging the Optimistic Virtual Machine (OVM), which is highly compatible with Ethereum’s EVM. This allows developers to port existing Ethereum dApps with minimal changes, reducing onboarding friction. The OP Stack, a modular framework for building L2 and L3 chains, fosters interoperability through the Superchain concept, attracting projects seeking customizable scaling solutions. Optimism’s simpler single-round fraud-proof system prioritizes transaction speed, appealing to dApps requiring quick finality, such as gaming or microtransactions.
