The invention relates to the technical field of
information processing, in particular to a commodity
supply management system based on a block chain. An interface switching module; the information classification storage module is used for carrying out partition storage judgment on the
user information according to the user identity, identifying sensitive information and carrying out fragmentation storage judgment on the sensitive information according to a random
algorithm; the
database is stored in a partitioned mode; a front-end
supply management module; a double-end coordination module; and a back-end maintenance module. Through information classified storage and random
algorithm fragmented storage of sensitive information,
data security is enhanced, the front-end
supply management module and the double-end coordination module are combined, the
automation degree and the working efficiency of the
system are improved, and the non-tampering and whole-course recording characteristics of the block chain are utilized, so that the information of each link of the supply chain is transparent and traceable, and the
management efficiency of the
system is improved. And the back-end maintenance module quickly identifies and processes system errors by using a
consensus algorithm, so that the influence of system faults on services is reduced.
