Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

An embodiment of a data storage method based on a block chain provided in this specification is as follows:

referring to fig. 1, which shows a processing flow chart of a data evidence saving method based on a block chain according to this embodiment, and referring to fig. 2, which shows a processing flow chart of a data evidence saving method based on a block chain applied to a transfer evidence saving scenario according to this embodiment.

Referring to fig. 1, the data certification method based on a block chain provided in this embodiment is applied to a contract platform, and specifically includes steps S102 to S108.

Step S102, according to a bill deposit request submitted by a first transaction party to which a transaction bill belongs, a data snapshot of the transaction bill is created, and deposit application data of the first transaction party is generated.

The block chain-based data certificate storing method provided by the embodiment achieves consensus of transaction bills of both transaction parties in a contract signing mode aiming at the transaction bills generated after the transaction of both transaction parties, achieves consensus of uploading the transaction bills to the block chain for certificate storing, and simultaneously records and links up related data of both transaction parties in the contract signing process, so that certificate storing data of the transaction bills on the block chain are more complete and comprehensive, a basis is provided for solving possible transaction disputes of both transaction parties around the transaction bills, a completed data basis is provided for electronic notarization files for subsequently generating the transaction bills, and the right maintaining cost for the transaction parties to solve the transaction disputes is reduced.

In this embodiment, the transaction party includes a user, a merchant, and a transaction platform such as an online selling platform and an online recycling platform that performs a transaction with the user or the merchant. The transaction bill refers to a bill generated after a transaction is carried out by two transaction parties or multiple transaction parties, the first transaction party refers to one or more transaction participating parties participating in the transaction, and the second transaction party refers to another transaction participating party or another transaction participating parties participating in the transaction.

For example, after the user and the merchant perform a transaction to generate a commodity transaction bill, the user is a first transaction party, and the merchant is a second transaction party; or after the transfer transaction is carried out between the two users to generate a transfer bill, the transfer initiator is a first transaction party, and the transfer receiver is a second transaction party; for another example, after a plurality of users jointly participate in a commodity transaction of an online shopping platform in an order-piecing manner to generate a commodity transaction bill, a first transaction party includes one or more users participating in the order-piecing manner, and a second transaction party includes the online shopping platform or other users except the online shopping platform and the first transaction party.

The bill deposit request in this embodiment refers to a request for the first transaction party to initiate uplink deposit of the transaction bill. Optionally, the bill deposit request is submitted to the block link point after the first transaction party triggers a deposit control configured on a bill display page of the transaction bill; the bill display page is created and displayed after the transaction of the first transaction part and the second transaction part is completed.

For example, after the user a transfers money to the user B through the application program and generates a transfer bill, a deposit button for depositing the transfer bill is configured and displayed on a display page of the transfer bill in the application program, and both the user a and the user B can initiate chain deposit of the transfer order by clicking the displayed deposit button at the first time when the transfer is completed and the transfer order is generated.

In addition, in order to further facilitate the transaction party to initiate the evidence saving of the transaction bill, optionally, the bill evidence saving request is submitted to the block link point after the first transaction party selects the transaction bill in the bill list page and triggers the evidence saving control; the billing listing page is accessed through an application page of an application. For example, after the user a transfers money to the user B through the application program and generates a transfer bill, the user a wants to initiate the deposit of the transfer bill within a period of time after the transaction is completed, the transfer bill can be searched and selected in the bill list of the application program, and the user a initiates the uplink deposit of the transfer order by clicking a deposit button generated after the transfer bill is selected.

In an optional implementation manner provided by this embodiment, the creating the data snapshot of the transaction bill specifically adopts the following manner, including: inquiring bill data corresponding to the bill identification based on the bill identification carried in the bill deposit request; and creating and storing a data snapshot of the transaction bill based on the inquired bill data.

In specific implementation, in order to improve the notarization effectiveness of the subsequently generated electronic notarization certificate, in the embodiment, in the process of performing chain storage on the transaction bill, the process data of the process of applying for the certificate storage by both transaction parties is recorded and chain storage is performed, and finally, the electronic notarization certificate is generated based on the certificate storage data of the transaction bill stored in the block chain and the process data of the process of applying for the certificate storage by both transaction parties, in an optional implementation manner provided in the embodiment, the certificate storage application data of the first transaction party is generated in the following manner:

acquiring a type keyword and an additional keyword of the transaction bill input by the first transaction party, and application operating environment information;

and generating and storing the evidence storage application data of the first transaction party based on the type keywords, the additional keywords and the application operation environment information. The evidence storing application data refers to process data of a first transaction party in the process of initiating the evidence storing of the transaction bill.

For example, in the process of saving the transfer bill of the transfer transaction with the user B, the user a inputs the transaction type (such as debit, transfer, payroll, house renting and the like) of the transfer bill, and inputs the key information (amount, transaction time, transaction place and the like) of the transfer bill, and in the process of generating the saving application data of the user a, the saving application data of the user a for the transfer bill is generated according to the transaction type of the transfer bill and the key information of the transfer bill input by the user a, the application environment information of the saving application initiated by the user a, and the data snapshot of the transfer bill.

And step S104, uploading the data snapshot and the evidence storage application data to the block link points, and sending an invitation of an evidence storage contract to a second trading party recorded in the trade bill.

It should be noted that, for evidence saving of the transaction bill, it is necessary for both parties of the transaction to achieve consensus on the transaction bill, and for evidence saving of data means on the consensus achieved by both parties of the transaction, which is used as a basis for solving a transaction dispute, in this embodiment, the first transaction party initiates an invitation for the second transaction party to invite the second transaction party to achieve consensus on the transaction bill for evidence saving, and in a first optional implementation manner provided in this embodiment, before sending an invitation of the evidence saving contract to the second transaction party, a keyword collection page of the transaction bill is generated and displayed to the first transaction party, and a type keyword and an additional keyword of the transaction bill input based on the keyword collection page are obtained; generating an offer for a vouching contract for the transaction bill based on the type keyword, the additional keyword, and the transaction bill.

When the contract platform is implemented specifically, the contract platform accesses a block chain, carries out chain link certificate storage on the data snapshot of the transaction bill and the certificate storage application data of the first transaction party, specifically uploads the data snapshot and the certificate storage application data to block chain link points in the block chain, and carries out certificate storage on the data snapshot and the certificate storage application data by the block chain nodes. On the other hand, the contract platform sends the invitation initiated by the first trading party to the second trading party, in particular sends the invitation of the evidence contract of the transaction bill to the second trading party recorded in the transaction bill.

And step S106, generating the confirmation signing data of the second transaction party under the condition that the deposit receipt is confirmed and signed.

After the invitation of the deposit contract of the transaction bill initiated by the first transaction party is sent to the second transaction party, the second transaction party may choose to sign the deposit contract, that is, confirm that the transaction bill is certified with the first transaction party, in this case, the confirmation signing data of the second transaction party is generated, where the confirmation signing data refers to process data of the second transaction party in the process of signing the deposit contract with the first transaction party.

In an optional implementation manner provided by this embodiment, the confirmation signature data of the second transaction part is generated as follows:

if a contract signing control configured on an invitation page of the certified storage contract is triggered, recording confirmation signing action data and application operating environment information of the second transaction party;

generating the validation signing data based on the validation signing action data, the application operating environment information, and/or the data snapshot.

Along the use example, in the process of storing the transfer bill of the transfer transaction between the user A and the user B, the user A sends a certificate storage contract for storing the transfer bill to the user B so as to invite the user B to agree and confirm the chain certificate storage of the transfer bill; here, after signing the deposit receipt contract to confirm the deposit receipt of the transfer account, the user B generates the confirmation signing data of the user B for the transfer account according to the signing action data of the deposit receipt contract signed by the user B, the application environment information of the deposit receipt contract signed by the user B, and the data snapshot of the transfer account.

Step S108, uploading the signature confirmation data to the block link point, so as to associate the signature confirmation data with the transaction bill and link up the deposit certificate.

After the confirmation signing data of the second transaction part are generated, the confirmation signing data are uploaded to a block chain node in a block chain accessed by a contract platform, so that the confirmation signing data are stored. The process data in the transaction bill storing process in this embodiment is composed of two parts of data, namely certificate storing application data of the first transaction party and confirmation signing data of the second transaction party, and after the block chain node receives the confirmation signing data uploaded by the contract platform, the block chain node associates the confirmation signing data with the data snapshot of the transaction bill uploaded in the step S104 and the certificate storing application data of the first transaction party, so that the electronic public certificate of the transaction bill is generated according to the data snapshot of the transaction bill, the certificate storing application data of the first transaction party and the confirmation signing data of the second transaction party. Specifically, after the confirmation and signing data is uploaded to the block chain node, the block chain node establishes association with the transaction bill based on a bill identification of the transaction bill included in the confirmation and signing data.

In practical application, when a transaction dispute occurs between two transaction parties or between multiple transaction parties, a core point for solving the transaction dispute often depends on whether effective evidence collection can be performed, and in this embodiment, on the basis that the two transaction parties achieve consensus on depositing the evidence of the transaction bill and process data in the process of achieving the consensus between the transaction bill and the two transaction parties are deposited, an electronic notarization voucher of the transaction bill is generated according to a notarization application provided by any transaction party or the two transaction parties, so that an effective voucher and a strong evidence are provided for solving the transaction dispute, in an optional implementation manner provided by this embodiment, the electronic notarization voucher of the transaction bill is generated in the following manner:

acquiring a notarization application submitted by the first trading party or the second trading party;

responding to the notarization application, and inquiring data snapshot, certificate storage application data and/or confirmation signing data of the transaction bill;

uploading the inquired data snapshot, the certificate storage application data and/or the confirmation signing data to a notarization platform, so that the notarization platform conducts data verification, and an electronic notarization certificate of the transaction bill is generated after the verification is passed; the electronic notarization certificate is an electronic notarization or electronic notarization file with judicial effectiveness;

and issuing the electronic notarization certificate of the transaction bill to the first transaction party or the second transaction party.

Optionally, the notarization platform specifically adopts the following method in the process of data verification: calling block chain nodes to inquire the data snapshot, the certificate storage application data and/or the confirmation signing data of the transaction bill stored in the block chain; comparing the inquired data snapshot, certificate storing application data and/or confirmation signing data with the data snapshot, certificate storing application data and/or confirmation signing data uploaded by the contract platform; and if the comparison result is consistent, generating the electronic notarization certificate of the transaction bill.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 30 s of the 20 th century, improvements in a technology could clearly be distinguished between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

Of course, the functions of the units may be implemented in the same software and/or hardware or in multiple software and/or hardware when implementing the embodiments of the present description.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
