The underlying shared chain is committed to expanding the application and technological boundaries of blockchain technology, so that ordinary internet users can feel the value of blockchain technology. In the underlying shared chain system, point-to-point value transfer can be achieved through the value transfer protocol, and a decentralized application development platform that supports multiple industries can be built based on this protocol. The underlying sharing chain can enable different enterprises and users on the same chain to improve the anti tampering and interoperability between chain nodes to improve efficiency, reduce operating costs, strengthen authentication, and protect data privacy.The vision of the bottom level sharing chain team is to build the best ecosystem, achieve value quantification and value circulation within the platform, build a data authenticity and uniqueness and trustworthy credit system, create a trustworthy ecosystem, and truly achieve the great vision of "bottom level interconnection, shared future"....
