About OPN, the Opinion Token
OPN is the official token of Opinion– a decentralised Information Finance prediction market that aims to solve the proxy trading problem, particularly for macroeconomic events, while maintaining pure exposure to real-world outcomes. This means traders can take direct, binary positions on specific economic indicators like FOMC rate decisions, CPI data, and employment figures, rather than relying on correlated assets to express a market view.
