Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the embodiments in the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, a method for storing block chain associated data provided in an embodiment of the present disclosure includes:
step 102: sending a first transaction for creating a first data tag to a blockchain, wherein the transaction content of the first transaction comprises the specific content of the first data tag, and after the first transaction is completed, returning a first tag address on the chain;
step 104: and sending a second transaction of the associated data certificate to the blockchain, wherein the transaction content comprises: the data to be stored and the first label address;
after the second transaction is completed, returning a data evidence storage address on the chain, and recording the mapping relation between the evidence storage address and the first label address on the block chain;
step 106: and sending a third transaction of the associated data query to the blockchain, wherein the transaction content comprises the first label address, searching a certificate storage address list which has a mapping relation with the first label address, obtaining certificate storage data according to the certificate storage address list and returning the certificate storage data as a third transaction result.
Optionally, the content of the first transaction includes a privacy identification of the first data tag;
when the privacy identification is valid, the second transaction can take effect only after the initiator of the second transaction obtains the authorization of the creator of the first data tag.
Correspondingly, when a second transaction of the associated data certificate is sent to the blockchain, whether an initiator of the second transaction is authorized or not needs to be checked, and the data certificate is stored after the checking is passed.
Optionally, the method further includes:
when the initiator of the second transaction obtains the authorization of the creator of the first data label, the creator of the first data label sends a fourth transaction to the chain of the creator of the first data label, and the transaction content is the user address of the initiator of the second transaction added to the use permission list of the first data label;
an initiator of the second transaction obtains the first tag address.
How to obtain the first tag address by the initiator of the second transaction is not specifically limited in the embodiment of the present invention. The initiator of the second transaction can inquire whether the user address is in the use authority list of the first data label through the transaction, and if so, automatically returns the first label address to the initiator of the second transaction.
Optionally, the method further includes: sending a fifth transaction for creating a second data tag to the blockchain, wherein the transaction content comprises the specific content of the second data tag, the identifier of the second data tag subordinate to the first data tag and the first tag address;
and after the fifth transaction is completed, returning the second tag address on the chain.
For example, in practical applications, such hierarchical tags can further refine stored data, and at the same time, can more conveniently collect and summarize multiple pieces of lower-level tag data through upper-level tags during query.
Optionally, the method further includes:
sending a sixth transaction of the associated data query to the blockchain, wherein the transaction content comprises the first tag address;
looking up the second tag address that is subordinate to the first data tag;
searching a certificate storing address list which has a mapping relation with the second label address; and obtaining the certificate storage data according to the certificate storage address list and returning the certificate storage data as a sixth transaction result.
In practical applications, before the second data tag is established, the creator of the first data tag needs to perform mutual authorization and authentication to establish the dependency relationship between the two data tags.
As can be seen from the above, the data content corresponding to the second data tag belongs to the subset of the content corresponding to the first data tag, and in practical application, by sending the certificate storing transaction and the query transaction with the second tag address, the certificate storing and calling of the content with only the second data tag can be realized, which is not described herein again.
According to the technical scheme, the logic association or the time sequence correlation between the data is embodied on the block chain by creating the data label, so that the block chain technology can be more flexibly adapted to the actual service, and convenience is provided for the inquiry, retrieval and utilization of the subsequent evidence data. Meanwhile, the form of the multi-level label is established, so that the stored data presents clear dependency relationship.
