Gnosis is a prediction market platform built as a decentralized application (dapp) on the Ethereum network. The platform includes a multisig wallet as well as a Dutch Exchange, but we��re just going to focus on their flagship product, the prediction market, for this guide. More than just building a prediction market, though, Gnosis is creating an entire infrastructure layer that you can use to build your own prediction market app.The Gnosis cryptocurrency, GNO, is an Ethereum-based token sold during the Gnosis ICO. The primary use case of GNO is for generating OWL tokens via staking. Users can lock GNO for a certain amount of time (up to one year) to earn rewards.For the Ethereum ecosystem, GnosisDAO creates decentralized infrastructure. Gnosis developed a wide range of products including Gnosis Safe (multisig and programable accounts), Gnosis Protocol (CowSwap), Conditional Tokens (prediction markets), Gnosis Auction, and Zodiac (standard and tooling for composable DAOs). After a token merger with xDai, GnosisDAO is proud to announce Gnosis Chain: An Ethereum forerunner-companion that addresses scaling issues through solid engineering.
