Centralized exchanges lack security,transparency and efficiency.Decentralized transactions are different from centralized exchanges.By operating on the key functionality of the block chain,users can control their own money:they use the technology behind the encrypted currency itself To achieve safer and more transparent transactions. Turing Club Chain,a project launched by the Turing foundation,goes to the center.A chemical exchange is designed to solve centralized trading by establishing a point-to-point market directly on the block chain (mainly in ethernet) This will allow traders to continue to manage funds.
