The steel asset transaction information includes: from public key, to public key, steel asset string, quantity, date, transaction string.
And at the same time of generating the steel asset transaction, destroying the steel asset registration information used by the delivery party for delivery (namely destroying the steel asset of the initiator), and generating new steel asset registration information for the receiver (namely generating the steel asset of the receiver). It may also be desirable to generate change-making steel asset registration information for the delivery party (i.e., generate a sender-side steel asset change) in view of the greater number of steel assets to deliver than are required to be delivered.
For example, a steel mill delivers 50 tons of special steel with XYZ specifications to a B bearing mill. A steel mill has 100 tons of special steel with the specification of XYZ and the furnace number of 123 in an intelligent contract module of a steel asset registration center. The a steel mill may initiate a transaction to the B bearing mill. The order in which the transactions are performed is:
submitting a special steel transaction with specification of XYZ to a 'steel asset registration center' intelligent contract module, wherein the special steel transaction is 50 tons in weight and is sent to a B bearing factory;
the method is characterized in that a steel factory A is destroyed to have 100 tons of special steel assets with specification of XYZ and furnace number of 123 in an intelligent contract module of a steel asset registration center;
generating a 50-ton special steel asset with the specification of XYZ and the furnace number of 123 for an A steel mill in an intelligent contract module of a steel asset registration center as change;
generating a 50-ton special steel asset with the specification of XYZ and the furnace number of 123 for a B bearing factory in an intelligent contract module of a steel asset registration center;
writing a stroke into a B bearing factory in an intelligent contract module of a steel asset registration center, wherein 50 tons of special steel transaction with the specification of XYZ;
in order to facilitate operation, the 'user operation interface' can provide a flexible query mode based on specifications, product codes, furnace numbers and steel asset character strings so as to quickly realize transaction.
Correspondingly, as shown in fig. 4, the principle of processing steel assets in the block chain-based anti-counterfeiting traceability system is described with reference to the embodiment:
the steel asset processing information comprises a public key, a processing archive character string, an input material array, an output quantity, a date and time and a steel asset processing character string. Wherein the input material array is [ array serial number, original steel file character string/steel product file character string, quantity ], wherein the quantity is input data, and the original steel file character string/product file character string comes from steel product processing file information. The output quantity is automatically generated according to the processing file information of the steel product.
At the same time of the steel asset processing generation, the steel asset registration information used as the processing input is destroyed (i.e., the input steel asset is destroyed), and new output steel asset registration information is generated (i.e., the processing result steel asset is generated). Considering that the number of steel assets to be processed is greater than the number of steel assets to be processed, it may be necessary to generate a steel asset registration message for change (i.e., generate an input steel asset change) for the processing manufacturer.
For example, according to the example given above, a B bearing plant produces a total of 49000 bearings of size UVW of 49 tons. According to the process file registration information, the machining requires special steel of XYZ specifications, and the yield is 98%, so 50 tons are required. And the B bearing factory has 50 tons of special steel with the specification of XYZ and the furnace number of 123 in an intelligent contract module of a steel asset registration center, and can initiate one-time processing. The sequence of executing the machining service is as follows:
submitting 49 tons of bearings with the specification of UVW to be produced, and processing 49000 pieces of bearings to a 'steel asset processing center' intelligent contract module in total, wherein the input raw material of the processing is 50 tons of special steel with the specification of XYZ and the furnace number of 123, which is owned by a B bearing factory in the 'steel asset registration center' intelligent contract module;
destroying 50 tons of special steel assets with specification of XYZ and furnace number of 123 which are owned by a bearing B factory in an intelligent contract module of a steel asset registration center;
generating 1 ton special steel assets with specification of XYZ and furnace number of 123 for a B bearing factory in an intelligent contract module of a steel asset registration center as change;
generating 49 tons of special bearing steel assets with the specification of UVW and the furnace number of 123 for a B bearing factory in an intelligent contract module of a steel asset registration center, wherein the total number of the special bearing steel assets is 49000;
writing a bearing with the specification of 49 tons and UVW into an intelligent contract module of a steel asset processing center, processing 49000 pieces of the bearing to the intelligent contract module of the steel asset processing center, wherein the input raw material of the processing is 50 tons of special steel with the specification of XYZ and the furnace number of 123, which is owned by a bearing plant B in the intelligent contract module of the steel asset registration center;
in order to facilitate operation, the 'user operation interface' can provide a flexible query mode based on specifications, product codes, furnace numbers and steel asset character strings so as to quickly realize transaction.
Finally, it is to be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
