The Forecast Chain (FCC) constructs an ecosystem network of prediction markets based on blockchain technology. Integrating blockchain technology with machine deep learning and the physics of collective intelligence, FCC automatically and securely predicts data, building a predictive network effect. It utilizes a token economy system to achieve a closed loop of value circulation of collective intelligence within the prediction ecosystem, constructing a circle of prediction markets based on blockchain technology. FCC is a token that embodies the ecological value of the Forecast Chain.
