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 is building Optimism mainnet, and by extension, the infrastructure that powers all OP-Stack chains. We are improving Ethereum’s performance by orders of magnitude and donating the profits from doing so to funding Ethereum public goods. By operating as a Public Benefit Corporation, OP Labs can align its incentives with the public good and take positive-sum steps toward a sustainable future for the internet.

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.
