According to the token economic model disclosed in the DePIN protocol http://io.net document, the fixed maximum supply of IO, the native token of the IOG network, is 800 million, of which 500 million IO tokens will be distributed at launch, including seed round investors (12.5%), A round investors (10.2%), core contributors (11.3%), R&D and ecosystem (16%) and community (50%). The remaining 300 million will be issued and paid to suppliers and their stakers every hour for 20 years as rewards, and the rewards follow a deflationary model, starting with 8% in the first year and decreasing by 1.02% per month (about 12% per year). IO uses a programmatic token destruction system, in which the revenue generated by http://io.net from the IOG network is used to purchase and destroy IO, and the destruction mechanism will adjust the destruction amount according to the price of IO. Foresight News notes that http://io.net said its token economic model is under revision and may be changed before launch.
