OKB is the utility token of the OKX ecosystem, a prominent global cryptocurrency exchange. OKB offers its holders benefits like trading fee discounts and exclusive access within the ecosystem. OKB is integral to the OKX ecosystem, used for availing discounts, earning passive income, and participating in token sales. Created by Mingxing "Star" Xu, the founder of OKX and CEO of OKCoin.com, OKB is part of a Buy-Back & Burn program initiated in 2019 to maintain its value, reducing the original total supply of 300 million tokens.
