Waltonchain is the underlying public business ecochain. It resorts to RFID technology to create a unique combination of blockchain and the Internet of Things (IoT). On this ecochain, merchants can create customized child chains and monitor production, logistics, warehousing and retailcirculation of all commodities. As a business ecochain, Waltonchain ensures that all data on it is authentic and credible. With the self-developed reader chip and tag chip, all data of physical commodities in circulation is automatically recorded to blockchain. Thus Waltonchain avoids human interface, minimizes the data tampering possibility and creates a fair, transparent, traceable and credible new-generation business ecosystem.
