What is OKB?
OKB is the native cryptocurrency of OKX, one of the world's leading cryptocurrency exchanges. OKB functions as a utility token within the OKX ecosystem, providing users with benefits such as trading fee discounts, participation in token sales on the OKX Jumpstart platform, and the ability to vote in governance decisions.
Initially launched as an ERC-20 token, OKB has since migrated to its own blockchain, providing increased scalability, transaction speed, and lower fees. OKB has a wide range of use cases within the OKX platform, including earning rewards, accessing exclusive services, and more.
With a fixed supply of 300 million tokens, OKB is designed to be deflationary over time, increasing in value as demand grows. It is an essential token for users who are active in the OKX ecosystem, providing real-world utility beyond just trading.
