Gnosis is a blockchain infrastructure company and ecosystem on 📝Ethereum, founded in 2015 by Martin Köppelmann and Stefan George out of the ConsenSys mesh, originally focused on a permissionless prediction-market protocol and now spanning a multi-product portfolio of on-chain infrastructure under the Gnosis name.
The protocol's native token, GNO, secures the Gnosis Chain — an EVM-compatible proof-of-stake network with low transaction fees and short block times, particularly favored for payments, micropayments, and consumer applications. Adjacent Gnosis-affiliated products include Safe (formerly Gnosis Safe), the dominant multi-signature smart-wallet platform across Ethereum and major layer-2 networks; CoW Protocol, a batch-auction decentralized exchange built on intent-based settlement; and the Gnosis Card and related real-world-payments stack that bridges Gnosis-Chain balances into conventional Visa rails. Several of these products have been formally spun out into independent organizations while retaining roots in the original Gnosis founding team.
