Commercial  Data  Storage (Commercial Data Distributed Storage), referred to as CDS for short. Focusing on the commercial data storage agreement, the design of CDS combines and transcends the decentralized technology concept of IPFS, and is built based on the POTS traffic storage consensus technology. Through the design of smart contracts, all commercial data and content based on CDS are recorded and saved, confidentiality and security are improved while achieving commercial data assetization. CDS is committed to solving trust, safe and efficient problems in global business transactions and promoting the development of commercial businesses. At this stage, we focus on promoting the development of all value trading businesses. In the future, in essence, it will promote the two-way development of trading business between commercial transactions and financial institutions. All commercial data can be stored and used safer and more stable in the CDS system.
