Gnosis is a decentralized forecasting market based on the Ethereum agreement. Gnosis provides an open platform for predicting the outcome of any event, greatly simplifying the creation of custom forecast market applications. At the same time, Gnosis leverages the trust of blockchain machines and the automatic execution of smart contracts to give players more flexibility and freedom to enter the forecasting market, giving the forecasting market an even greater amount of room for imagination. In the future, Gnosis participants do not even need to be natural persons. In the Internet of Things, the information collected by the sensors can also be easily entered into the blockchain as information assets to buy and sell.
