OKB, a cryptocurrency issued by the OK Blockchain Foundation in collaboration with the Maltese crypto exchange OKEx, serves as a key utility token for accessing special features on the platform. OKEx, one of the world's largest exchanges, currently holds the third position in liquidity and fourth in trading volume, offering a wide array of trading pairs. While OKEx shares similarities with the cryptocurrency exchange giant Binance, it distinguishes itself through certain features. For instance, OKEx operates its own cloud mining service and has a more focused approach towards providing options trading for its users. In contrast, Binance aims to offer a comprehensive range of crypto services on a global scale. OKB facilitates various functions within the OKEx ecosystem. It is utilized for calculating and paying trading fees, providing users with voting and governance rights on the platform, and rewarding users for holding OKB tokens. Since its inception in 2017, OKEx has rapidly ascended to become a leading trading platform. Originating as an offshoot from the original OKCoin platform, which has been operational since 2013 in China, OKEx primarily focuses on crypto trading, offering built-in API functionality for algorithmic trading. The exchange also offers users access to a multi-currency wallet and features for margin trading.
