Gnosis was the first major decentralized application to launch on Ethereum. Gnosis provides a decentralized prediction market and governance tool. Prediction markets can work in various industries, such as stock markets, event betting, and so on. By using a decentralized approach to prediction, the hope is that such predictions are more accurate because of a greater variety of information entering the market to adjust projections.

As one of the earliest adopters of Ethereum, the Gnosis team also puts a lot of energy into various tools such as multi-signature wallets.
