Gnosis is a company that was founded in 2015 as part of ConsenSys, an Ethereum venture production studio.

In April 2017, it became an independent company. The company's mission is centered around experimentation and building decentralized infrastructure for the Ethereum ecosystem. Initially, Gnosis focused on building prediction markets to provide global access to accurate information. However, in order to support this platform, the company needed to develop the necessary infrastructure.

Some of the products incubated by Gnosis include Gnosis Safe (storing over $47B in assets), Cow Protocol (formerly CowSwap), Conditional Tokens (prediction markets), Gnosis Auction, and Zodiac (standard and tooling for composable DAOs).

In November 2021, the xDAI and GnosisDAO community voted to combine their ecosystems and create the Gnosis Chain. Gnosis Chain is an EVM-compatible, community-owned network that prioritizes credible neutrality and resiliency. It utilizes the xDai token and encompasses a diverse range of projects and users.

Gnosis Chain is secured by over 150k validators worldwide and is compatible with all future Ethereum EIPs. It uses the same execution layer and consensus layer clients as Ethereum.
