In the case of, the technology, method and apparatus should be considered as part of specification.For between each unit in attached drawing
Line, it is only for convenient for explanation, indicate that the unit at least line both ends is in communication with each other, it is not intended that limitation does not connect
It can not be communicated between the unit of line.
Fig. 1 is the flow chart 100 of the source tracing method based on block chain of embodiment according to the present invention.
Step S101: the characteristic information of commodity is obtained.In one embodiment, characteristic information include commodity source area and
Certificate number.
Step S102: it if characteristic information does not exist in the block chain account book, is obtained by tracing to the source intelligent contract
It obtains identifier corresponding with characteristic information and characteristic information and identifier is stored in block chain account book.
Step S103: by the intelligent contract of tracing to the source that the circulation information of commodity is associated with the identifier.One
In a embodiment, circulation information includes the dealing information, declaration information and quality information of commodity.
It should be understood that commodity herein are primarily referred to as luxury goods, luxury goods include the jewel of import and other valuable
Commodity.
Next, by by taking the process of circulation of diamond as an example, the technical solution that the present invention will be described in detail.
Fig. 2 is the flow chart 200 of the source tracing method according to an embodiment of the invention based on block chain.
Step S201: intelligent contract is disposed on block chain.It should be understood that intelligent contract here includes intelligent contract of tracing to the source
With intelligent contract of trading.
Step S202: user account is registered on block chain and obtains account corresponding with user account address.It should be understood that
, each participant of the process of circulation of diamond is (for example, foreign exporter, domestic importer, domestic buyer and supervision
Side) user account can be registered in block chain and obtain corresponding account address.Although will also be appreciated that in the present embodiment
Step S201 is before step S202, but step S202 can also be before step S201 or step S201 and step S202
It carries out simultaneously.
Step S203: the characteristic information of diamond is uploaded to block chain.Herein, the characteristic information of diamond include: source area,
Certificate number, weight, color, cleanliness, cutting, polishing grade and symmetry etc..Wherein, certificate number include certificate type and
Certificate number, for example, in one example, the certificate type of diamond is GIA, certificate number 21XXXXXX56, certificate type and card
Book number is bonded the certificate number of the diamond.It should be understood that the type of certificate can be other types such as NGCT.
Step S204: if the certificate number of diamond is already present in block chain account book, S205 is thened follow the steps, otherwise
Execute step S206.
Step S205: it sends a warning message to monitoring party (for example, Shanghai diamond exchange), to prompt the feature of diamond to believe
Breath is already present in block chain account book or exists in the process of circulation of diamond the forgery behavior of set card.
Step S206: the characteristic information of diamond is handled by tracing to the source intelligent contract opposite with characteristic information to obtain
The identifier (also referred to as diamond card number) answered.In one embodiment, identifier is by intelligent contract of tracing to the source to the spy of diamond
Reference breath carries out the cryptographic Hash corresponding with characteristic information of Hash operation acquisition.It should be understood that identifier here can be it is logical
Cross the symbol for capableing of unique identification characteristic information or the code etc. of other way acquisition.
Step S207: characteristic information and identifier are stored in block chain account book.
Step S208: it is by intelligent contract of tracing to the source that the circulation information of diamond is associated with identifier, so that passing through mark
Symbol can inquire the characteristic information and circulation information of diamond.For example, when for the first time from external import to the country, circulation information
Including dealing information (information i.e. in deal contract, the price of the diamond including dealing, information of both parties etc.), declaration
Information and/or related authoritative institution (NGTC, jewel and jade administrative center, Ministry of Land and Resources) reflect to the quality that diamond is made
Determine information (or quality information).After entering the country, circulation information mainly includes dealing information.
In another embodiment, further include after source tracing method based on block chain step S208 shown in Fig. 2 with
Lower step: according to the dealing information in circulation, the right of attribution information of diamond is changed by trading intelligent contract.For example, first is used
Diamond A is sold to party b subscriber by family, intelligent contract the returning diamond A of transaction according to the dealing information between first and second, on block chain
Belong to Quan Congjia and is changed to second.
In another embodiment, source tracing method step S208 shown in Fig. 2 based on block chain or according in circulation
Dealing information, by further including following after step of the intelligent contract of trading to change the right of attribution information of diamond: according to block
Account address list in chain determines the information search access right to the commodity.Wherein, if the stream for taking part in diamond passes through
Journey, then the account address of participant can be included in account address list, when the subsequent information for needing to inquire diamond, using account
Account address in the list of location, which carries out inquiry, can have permission all information (the feature letter i.e. including diamond for inquiring diamond
Breath, circulation information and diamond card number), and the account address not in account list is used to be only capable of inquiring the characteristic information of diamond.
It should be understood that above-described embodiment only elaborates the process of circulation of diamond, but the above method is suitable for other
Similar luxury goods.
Block chain technology is introduced into the entire process of circulation of luxury goods by the present invention, be can be realized and is traced back to luxury goods
Source reduces risk and supervision cost in luxury goods process of exchange, and inhibits the market circulation of smuggling luxury goods.
