KLT is the token of Klein Chain, a public chain focusing on decentralization. Klein Chain is dedicated to addressing typical issues existing in Over-The-Counter (OTC) trading, such as the moral hazard of intermediaries, security of transaction assets, privacy protection for OTC merchants, and decentralized matching, among others. Klein Chain adopts a DPOS algorithm improved independently as its consensus mechanism, while simultaneously supporting smart contracts to enhance the value of its projects. Based on blockchain technology, Klein Chain realizes matching on-chain and stores matching orders in real-time into the corresponding chains for settlement and profit sharing in the transaction chain. Through cross-chain atomic swap technology, asset settlement is achieved. The combination of these two technologies significantly enhances the safety, privacy, and efficiency of OTC platforms compared to traditional OTC.
