Jinglan (Jing) Wang (Co‑Founder and CEO of Optimism)
Optimism protocol is a leading Ethereum Layer 2 scaling solution and the foundation of the Superchain ecosystem.
It emerged as one of the most influential forces in crypto through pioneering optimistic rollups and the open-source OP Stack, powering high-profile chains like Base.
In 2025, Optimism stands out for advancing the Superchain vision with significant upgrades, including Superchain Upgrade 16a, enhanced interoperability, and governance improvements, thereby solidifying its role in unifying multiple chains for scalable Ethereum adoption.
Optimism launched its mainnet in January 2021 with the initial vision of scaling Ethereum via optimistic rollups to provide low-cost, fast transactions while maintaining Ethereum’s security.
Founded by Karl Floersch and others, it evolved from early experiments to introduce the OP Stack in 2022, a modular framework for building custom chains, and the Superchain concept in 2023, envisioning a network of interconnected OP Chains sharing security, governance, and revenue models.
In 2025, Optimism has continued to shape the crypto conversation by driving Superchain interoperability upgrades, security enhancements, and revenue-sharing models that align incentives across chains.
This influenced other builders to adopt OP Stack for new networks, boosting investor confidence in modular scaling and expanding user access to low-fee transactions via chains like Base, which contributed to Ethereum’s L2 dominance.
Optimism is set to implement Superchain protocol upgrades for configurable blockspace, native cross-chain messaging, and deeper integration with Ethereum scaling efforts, such as Fusaka.
Tied to modular blockchains and Ethereum’s multi-chain future, it promises sustainable growth through revenue buybacks and ecosystem reinvestment.
Challenges include competition from other Layer 2s, but its standardized approach positions it as core infrastructure, potentially processing a significant share of Ethereum transactions as Layer 2s scale toward 80% dominance by 2028.
