The application relates to the technical field of blockchains, and discloses a mobile product whole-life-cycle tracing method based on a
blockchain, which comprises the following steps: a
relay chain extracts compliance judgment indexes in administrative rule update data, generates
compliance check salt values in combination with time stamps, and distributes the
compliance check salt values to parallel chains of each
business domain; the parallel chains of the
business domain map material tracing data and the
compliance check salt values, generate business state vectors containing local details and embedding time-effect features of the compliance judgment indexes; and the
relay chain implements logical check on the collected business state vectors by using an orthogonal state
mask, anchors to a global tracing ledger after verifying a compliance
time sequence, and establishes a strong
time sequence constraint benchmark of management logic in a heterogeneous chain by the compliance check salt values, eliminates compliance risks caused by rule replacement
lag of local nodes, and ensures response efficiency of cross-chain tracing under a
mass transaction condition by using a bit operation mechanism.
