Commercial data storage (financial flow storage protocol), referred to as CDs. Based on the consensus technology of pots (proof of traffic measured storage) and dedicated to financial traffic storage, it is committed to the trust, security, efficient problem solving of financial transactions and the promotion of financial business development. The design of CDs combines the well-known distributed technology concept of IPFs, and considers the special needs of financial data flow, and finally determines to build a consensus technology based on pots traffic storage. Through the design of intelligent contract, it records and saves all the digital information and content of financial transactions based on CDs, so as to improve the confidentiality and security, and realize the capitalization of personal data, CDS can be more specialized in the realization of reliable and safe efficient global financial transactions. At present, CDs is dedicated to promoting the development of individual trading business. In the future, it will be dedicated to promoting the development of trading business between financial institutions. Here: pots, the future development of the consensus, is to upgrade the mining machine into a personal server node through the system, break the traditional single one concept of mining for the purpose of mining, truly make the distributed storage obtain practical application value, and integrate and utilize the idle social resources, so as to achieve decentralization, more security, and more sustainable development The core of the technical team of CDs, a more efficient cryptocurrency value management and information recording system, is from the United States. It has been committed to the research and development of payment networks and protocols in the financial field, and has been applied to financial transactions between individuals and institutions, as well as the storage of financial transaction data. In the financial field, including personal, banking, securities, insurance and other industries, it often occurs in transactions. The distrust of both sides leads to low transaction efficiency, the privacy of transaction data can not be guaranteed, the loss of financial data, and even the loss of user assets caused by the data records can not be saved safely. As a result, trust, efficiency and security become obstacles to the development of business in the financial field, At the same time, personal data privacy is used arbitrarily without knowing, which has been criticized by all parties involved in the transaction and the public. In order to solve the industry problems, CDs is based on its original technology Combined with the consensus mechanism of pots traffic storage in blockchain, a new financial traffic storage protocol is developed.
