Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
The present invention is described by taking track information as an example, but the present invention is not limited to the track information. A block chain-based digital certificate system for a school trail chain generally comprises an organization end, a student end and a block chain. The organization end is mainly used for issuing and managing certificates; the student end mainly inquires the certificate information of the student end; the blockchain is mainly to synchronize each successive data. The block chain is typically a federation chain. Hereinafter, a blockchain, a federation chain, and a blockchain federation chain may refer to the same concept, depending on the context.
The organization end is generally provided with a track information storage system for storing and managing track information, wherein the track information comprises one or more of information such as issuing organization information, holder information, certificate content information, learning process records and learning result records, the track information is filled into a certificate template to form certificate information, and the certificate information also comprises link information such as uplink time, whole network synchronization time and the like. When the certificate information is displayed in the form of a certificate, the certificate is formed.
A first aspect of this embodiment provides a method for previewing a blockchain digital certificate, including:
step S101: receiving the trace information;
step S102: and displaying the certificate corresponding to the received trace information, wherein the page structure used for displaying the certificate is the same as the page structure used for browsing the certificate after chain winding. The uplink uploads the received trace information to the blockchain.
According to one embodiment, the presentation of the certificate may be performed in synchronization with the receipt of the information. For example, in the case shown in fig. 2, the certificate presentation may be updated each time a field corresponding to the certificate template is received, for example, when the family graduation is input, the family graduation is presented in the certificate presentation. After the serial number is input, the serial number is displayed immediately, and the display can be performed without waiting for the completion of the input of other fields corresponding to certificate templates such as hospital systems, specialties and the like.
According to one embodiment, the certificate presentation and the receipt of the trace information may be in one interface.
The certificate display structure adopts an adaptive design, which can adapt to different display devices (for example, machines with different screen sizes such as an IPAD, a computer or a mobile phone) under the condition of unchanged structure, and the adaptive technology can be completed by adopting various technologies known in the art. For example, it may be implemented using JavaScript native language, e.g., using align center, width usage percentage, etc., and the whole procedure may be completed by function call. Thus, students and the like can conveniently browse their own certificates and can see the complete certificates.
According to one embodiment, when receiving the trace information, the length of the column for receiving each field of the trace information is adaptively adjusted according to the input length of each field, and the displayed certificate is also adaptively displayed according to the length of each field of the received trace information. Such as automatically wrapping lines, increasing or decreasing word or segment spacing, changing graphic size, etc., to enable the certificate to fit the screen. A field may refer to an individual piece of content, such as a particular department, a particular specialty, or both.
According to one mode, the method further includes step S103, step S104 and step S105, and in step S103, information of the newly added block in the blockchain federation chain is obtained. Because data is written into the block chain, a new block, i.e., a newly added block, is allocated in the block chain. A blockchain federation chain includes a plurality of nodes, each node capable of communication and data synchronization, and each node may include one or more blocks that can be used to store data. And a new block can be applied, or a newly added block can be simulated, and the actual application is carried out when the actual uploading is finished. The obtained information may include whether the new block can be applied successfully, the height of the new block, and its possible identifier. In step S104, the height value of the newly added block in the block chain is obtained. The height value is the serial number of the newly added block in the block chain, i.e. the number of blocks owned by the current block chain after the newly added block is added. And S105, performing animation display according to the height value, and displaying the positions of the displayed certificates in all the certificates stored in the blockchain. According to one embodiment, the animation is a three-dimensional card-overlapped animation, the card-type certificate is overlapped in a three-dimensional manner, and the higher the height of the newly added block in the block chain is, the higher the corresponding three-dimensional card is displayed. This effect can make the recording personnel feel time vicious and improve the responsibility. The positions of the certificates to be entered in all the certificates can also be displayed in the form of a histogram or the like according to the height of the newly added block in the block chain, or displayed by taking time as a measure, such as displaying by years or displaying by specialties. When the certificate is displayed in a professional, the position of the certificate in the professional can be represented, or further comparison with other professionals can be displayed. In one embodiment, the height value is presented in an animation. According to one embodiment, the height value is also displayed in the certificate display.
In the present invention, the steps are numbered only for convenience of description, and different steps are distinguished, and do not represent the sequence of the steps. The animation display can be performed before the certificate display, and can also be performed alternately with the certificate display.
According to one embodiment, when the animation is displayed, the latest height value of the block chain and the related information of the previous height, such as the uplink time, etc., are also displayed.
In an embodiment, the method further includes a block height monitoring step S106, where, due to parallel operation and other reasons, in the recording process, before winding, the block height information is updated in real time, and step S106 detects the update, and if a new block is added in the middle, the block height information related to the current page is updated in real time, so that the user can obtain more detailed information such as the block chain height in real time while editing. And then, performing animation display according to the updated block height value.
According to one embodiment, the simulated on-chain information is presented when the certificate presentation is performed. The certificate shows that the on-chain information is not present when the trace information is not really uploaded to the block, and the blank on-chain information is not beneficial to the examination of the certificate, so that the simulated on-chain information can be provided. According to one embodiment, the uplink time and the network-wide synchronization time (network-wide ack time) are determined according to the current time. The current time itself may be used, or the time calculated according to the current time may be used. The identification information, such as the certificate number, on the chain may be generated randomly or using some algorithm.
The certificate is displayed at least before the learning information is uploaded while the learning information is received, so that errors can be found more intuitively.
After the reception of the trace information is completed, in step S107, uploading and saving are performed. And uploading the trace information confirmed by the check to a block chain, and storing corresponding certificate information.
Fig. 3 is a schematic flowchart of an upload and save step of a trace information certificate preview method according to an embodiment of the present invention. As shown in fig. 3, in this embodiment, for step S107, first, in step S10, the received trace information is uploaded to the newly added tile of the tile chain. And in step S20, the uplink time and hash value generated when the trace information is uploaded to the new chunk are obtained. The hash value is unique. Thus, the uploading time and content of the trace information can not be modified.
Step S30: and indicating the newly added block to carry out full network data synchronization on all nodes in the blockchain alliance chain. Wherein, for a federation chain, full network synchronization is limited to participants in the federation chain. The read authority of all nodes in the alliance chain can be public, and can be limited to participants like write authority, and the consensus process is controlled by the preselected node.
Step S40: and acquiring the whole network synchronization time generated when the newly added block carries out whole network data synchronization. The full network synchronization time may be referred to as the public time.
Step S50: and storing the trace information, the identification of the newly added block, the uplink time, the hash value and the whole network synchronization time. This saving in effect forms a certificate.
The above steps of the present invention may be performed by a track information storage system, and the information involved in step S50 may be stored in a database of the track information storage system.
The above steps S101 to S107 may be repeatedly executed, so as to upload a plurality of different trace information, each trace information having a corresponding new block when being uploaded.
When the blockchain federation chain is used only to store trace information, the blockchain federation chain becomes a trace blockchain. The track blockchain may be used for certificate issuance, learning processes and learning outcome records and corresponding authentication and querying using federation chain techniques.
In the embodiment, the trace information, the chaining time, the hash value and the whole network synchronization time are stored in the trace information storage system for management, and when the trace information storage system inquires the trace information, the chaining time, the hash value and the whole network synchronization time of the corresponding block can be checked at the same time, so that decentralization is realized, the trace information is managed conveniently and quickly, and is anti-fake, permanently stored and not falsified, and fake and embezzlement are effectively prevented.
