The decentralised prediction marketplace built on the Ethernet protocol provides an open platform for people to predict the outcome of any event, greatly simplifying the process of creating custom prediction marketplace applications. At the same time, Gnosis makes use of the blockchain trust machine and the automatic execution of smart contracts to give players more flexibility and freedom to enter the prediction market, bringing even greater imagination to the prediction market. In the future, participants in Gnosis do not even need to be natural persons. In the Internet of Things, the information collected by sensors can also be easily entered into the blockchain as information assets to be bought and sold. An important potential application of Gnosis is in the insurance industry, where Gnosis can facilitate market making to help individuals or companies hedge against the risk of arbitrary outcomes they do not want to occur. Insurance companies can also use the highly accurate nature of prediction markets to access information on the Gnosis platform to complement actuaries. Prediction markets based on ethereum smart contracts can be highly automated. Insurers can reduce the risk of loss or even profit from the market by automating trading through smart contracts.
