From a scalability-demand perspective, Ethereum Layer 2s in 2025 are positioned as core infrastructure rather than speculative extensions. Optimism’s competitive edge lies in its strong alignment with Ethereum’s long-term roadmap, particularly through its close collaboration with core Ethereum developers and its early adoption of the OP Stack. This positions Optimism as a modular scaling framework, while Arbitrum’s advantage comes from its technical maturity and consistently high transaction throughput, making it attractive for applications prioritizing performance and reliability.
