Who are we?

We believe Ethereum has the potential to solve some of humanity’s most crucial coordination issues. Since our initial inception as a research group, we have sought to scale both its technology and values.

At present, the most pressing bottleneck to the growth of Ethereum is its performance and scalability. We are building the most elegant solution to this problem. We do this in the open (under an MIT open source license) because we believe in open source innovation and its ability to accelerate growth.

OP Labs contributes to the Optimism protocol, an extension to Ethereum that scales both its technology and values. Optimism enables orders of magnitude of improved performance and scalability to Ethereum while doubling down on its commitment to public goods.

The Optimism Collective leads the blockchain protocol landscape, dedicated to fostering a scalable and sustainable ecosystem. Optimism’s ethos, in sync with Ethereum's vision, tackles pivotal coordination challenges of the digital age. Optimism’s goal is to harmonize private incentives with public good, shaping a resilient future for the Internet. Optimism’s scope spans diverse areas like Gaming, DeFi, NFTs, and Enterprise.
