The biggest problems of centralized settlement and clearing institutions are low efficiency and high cost, because it uses a two-tier clearing system: centralized clearing institutions clear directly to clearing members, which are usually first-class financial institutions, retail brokers, The client is cleared separately. The application of blockchain technology allows transaction users to settle directly, which eliminates the need for a centralized clearing and settlement institution, and the efficiency of the entire market will be greatly improved.
