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.

One or more embodiments of the present specification provide a method, an apparatus, and a device for verifying block chain data, where service data is stored in a first block chain in advance, and verification information of the service data is stored in a second block chain, so that when a first user needs to verify the service data, the service data to be verified is obtained from the first block chain through a terminal device of the first user, and the verification information of the service data is obtained from the second block chain, so that the service data can be verified according to the obtained verification information. Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data in the first block chain, and therefore, the requirement of the first user on verification of the service data is met on the basis that excessive resources of the first user are not occupied.

Fig. 1 is a schematic view of an application scenario of a verification method for blockchain data according to one or more embodiments of the present disclosure, as shown in fig. 1, the system includes: a terminal device of a first user, a first block chain node and a second block chain node; the terminal equipment of the first user can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like; the first block chain node is a node in a first block chain, and the first block chain is used for storing service data of a user; the second block chain node is a node in a second block chain, and the second block chain is used for storing the verification information of the service data in the first block chain; the terminal equipment of the first user is in communication connection with the first block chain node and the second block chain node through a wireless network; further, the first blockchain and the second blockchain may be union chains or public chains.

Specifically, when the first user needs to verify the service data stored in the first blockchain, the first user may operate the terminal device thereof to send a data verification request to the terminal device; the terminal equipment of the first user responds to a data verification request of the first user, acquires service data to be verified from the first block chain, and acquires verification information of the service data to be verified from the second block chain; and verifying the service data to be verified by adopting the acquired verification information. The business data includes transaction data, enterprise operation data, user identity data, and the like. Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data in the first block chain, and therefore, the requirement of the first user on verification of the service data is met on the basis that excessive resources of the first user are not occupied.

Based on the application scenario architecture, one or more embodiments of the present specification provide a method for verifying blockchain data; fig. 2 is a flowchart illustrating a method for verifying blockchain data according to one or more embodiments of the present disclosure, where the method in fig. 2 can be executed by a terminal device of a first user in fig. 1, and as shown in fig. 2, the method includes the following steps:

step S102, acquiring service data to be verified from a first block chain; the first block chain is used for storing service data of a user;

the service data to be verified may be service data of a first user or service data of a second user; the second user is a user other than the first user, and it should be understood that in a specific scenario, the user identity referred to by the first user and the user identity referred to by the second user in this specification may be replaced with each other.

Step S104, obtaining the verification information of the service data from the second block chain; the second block chain is used for storing the verification information of the service data in the first block chain;

after the verification information of the service data is that the first user or the second user stores the service data to be stored to the first block chain, the terminal device of the first user or the terminal device of the second user generates the verification information based on the service data to be stored.

And step S106, verifying the service data to be verified according to the acquired verification information.

In one or more embodiments of the present specification, a terminal device of a first user can, in response to a data verification request of the first user, obtain service data to be verified from a first blockchain, obtain verification information of the service data from a second blockchain, and verify the service data according to the obtained verification information. Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data in the first block chain, and therefore, the requirement of the first user on verification of the service data is met on the basis that excessive resources of the first user are not occupied.

When the first user needs to verify the service data of the first user, before the verification, the first user first stores the service data into the first block chain through the terminal device of the first user, specifically, as shown in fig. 3, before step S102, the method further includes:

step S100-2, sending a first data storage request to a first block chain node; the first data storage request comprises service data to be stored, so that the first block link node stores the service data and the first hash value in a first block chain in an associated manner;

step S100-4, receiving a first hash value sent by a first blockchain node.

The first hash value is a hash value calculated by the first block link point based on the service data and the additional data; specifically, the terminal device of the first user responds to the data storage operation of the first user and sends a first data storage request to the first block chain node according to the service data to be stored; when a first block link node receives a first data storage request, acquiring service data from the first data storage request, calculating the service data and additional data according to a second preset algorithm to obtain a first hash value, storing the service data and the first hash value in a first block chain in a correlation manner, and sending the first hash value to terminal equipment of a first user so that the terminal equipment of the first user inquires the service data according to the first hash value; the terminal equipment of the first user receives and stores the first hash value sent by the first blockchain node; in practical applications, the additional data may be set as needed, such as the receiving time of the first data storage request received by the first block node, the block identifier of the block storing the service data, and the like. The first user can effectively prevent the service data from being lost and the service data from being maliciously tampered and the like based on the characteristics of the block chain by storing the service data into the first block chain.

In order to enable a first user to verify the service data stored in the first block chain and enable other users to verify the service data of the first user, after the terminal device of the first user receives a first hash value sent by a first block chain node, the terminal device of the first user also determines verification information of the service data according to the service data to be stored (namely original service data) included in a first data storage request, and stores the verification information into a second block chain through a second block chain node of the second block chain; specifically, as shown in fig. 3, after step S100-4, the method further includes:

s100-6, calculating a second hash value of the service data to be stored according to a first preset algorithm;

step S100-8, sending a second data storage request to a second block chain node; the second data storage request comprises a first hash value and a second hash value, so that the second block chain node stores the first hash value, the second hash value and a third hash value in a second block chain in a correlation manner, and the third hash value is a hash value calculated by the second block chain node based on the first hash value and the second hash value;

and S100-10, receiving a third hash value sent by the second blockchain node.

Specifically, because the first block link point is maliciously controlled, or the service data stored in the first block chain is incorrect due to other factors, in order to enable a user to verify the integrity and accuracy of the service data stored in the first block chain in the subsequent process, when the terminal device of the first user receives a first hash value sent by a first block chain node, a second hash value of the service data to be stored included in the first data storage request is calculated according to a first preset algorithm, and a second data storage request is sent to a second block chain node according to the first hash value and the second hash value; when the second block link node receives a second data storage request, calculating the first hash value and the second hash value according to a third preset algorithm to obtain a third hash value, storing the first hash value, the second hash value and the third hash value into a second block chain in an associated manner, and sending the third hash value to the terminal equipment of the first user, so that the first user can inquire corresponding verification information according to the third hash value; and the terminal equipment of the first user receives and stores the third hash value sent by the second blockchain node.

Therefore, after the first user saves the service data to be stored to the first block chain, the second hash value is calculated based on the service data to be stored, the second hash value and the third hash value are saved to the second block chain, and the corresponding service data saved in the first block chain is verified based on the hash value saved in the second block chain subsequently.

In one or more embodiments of the present disclosure, in order to quickly and conveniently acquire service data when a first user wants to verify whether own service data stored in a first block link point is correct, the first user sends a service data query request to the first block link point through a terminal device of the first user, so that the first block link point quickly queries corresponding service data according to a first hash value in the service data query request; specifically, as shown in fig. 4, step S102 includes:

step S102-2, a service data query request is sent to a first block link point in a first block chain, wherein the service data query request comprises a first hash value, so that the first block link point queries related service data from the first block chain according to the first hash value;

as described above, the first hash value is a hash value calculated by the first block link point based on the service data and the additional data when the first user stores the service data to be stored to the first block chain through the first block link point in advance. Specifically, the terminal device of the first user responds to a data verification request of the first user and sends a service data query request to a first block link node in a first block chain according to a stored first hash value; when the first block link receives a service data query request, the service data stored in association is queried in the first block link according to a first hash value included in the service data query request, and the queried service data is sent to the terminal equipment of the first user.

And step S102-4, receiving the service data sent by the first block chain node.

Further, in order to verify the obtained service data, the terminal device further sends a verification information query request to a second block link point in the second block chain to obtain corresponding verification information, specifically, as shown in fig. 4, step S104 includes:

step S104-2, sending a verification information query request to a second block link point in a second block chain, wherein the verification information query request comprises index information of verification information to be queried, so that the second block link point queries related verification information from the second block chain according to the index information;

and step S104-4, receiving the verification information sent by the second blockchain node.

Specifically, the terminal device takes the stored first hash value and/or the stored third hash value as index information of the verification information to be queried, and sends a verification information query request to a second block link node in the second block chain according to the index information; when the second block link node receives the verification information query request, querying the hash value stored in a correlation manner from the second block link according to the index information included in the verification information query request, and sending the queried hash value serving as the verification information to the terminal equipment of the first user; and the terminal equipment of the first user receives the verification information sent by the second blockchain node.

When the service data to be verified and the verification information of the service data are obtained, the service data can be verified according to the verification information. Specifically, when the index information includes the third hash value, correspondingly, the verification information includes the first hash value and the second hash value; step S106 includes:

step S106-2, determining whether the first hash value included in the verification information is consistent with the first hash value stored in the terminal equipment;

step S106-4, calculating a fourth hash value of the acquired service data according to a first preset algorithm, and determining whether the calculated fourth hash value is consistent with a second hash value included in the verification information;

and step S106-6, if the data are consistent, the service data is determined to pass the verification.

The execution sequence of the step S106-2 and the step S106-4 can be interchanged; further, when it is determined that the first hash value included in the verification information is consistent with the first hash value stored in the terminal device, it may be determined that the obtained verification information is the verification information of the service data to be verified; when it is determined that the fourth hash value is consistent with the second hash value included in the verification information, it may be determined that the service data acquired from the first blockchain is correct, that is, the service data stored in the first blockchain is not tampered. Therefore, effective verification of the authenticity of the business data is achieved based on the first hash value and the second hash value.

Further, when the index information includes the first hash value, or the index information includes the first hash value and the third hash value, correspondingly, the verification information includes the second hash value, and step S106 includes:

step S106-8, calculating a fourth hash value of the acquired service data according to a first preset algorithm, determining whether the fourth hash value is consistent with a second hash value included in the verification information, and if so, determining that the service data passes the verification.

When it is determined that the fourth hash value is consistent with the second hash value included in the verification information, it may be determined that the service data acquired from the first blockchain is correct, that is, the service data stored in the first blockchain is not tampered. Therefore, based on the second hash value, effective verification of the authenticity of the business data is achieved.

In the above, the terminal device of the first user, in response to the data verification request of the first user, obtains the service data of the first user from the first blockchain based on the stored first hash value, obtains the verification information of the service data of the first user from the second blockchain based on the terminal device storing the first hash value and/or the third hash value, and verifies the obtained service data based on the obtained verification information. Therefore, for the first user, the terminal device does not need to be deployed as a node device to join the block chain, the terminal device of the first user does not need to participate in consensus verification in the block chain, and all data in the block chain are not needed to be stored in the terminal device of the first user, so that the verification requirement of the first user on the service data of the first user is met on the basis of reducing the operation of the terminal device of the first user and reducing resource consumption.

Further, the first user may also verify the service data of the second user based on the service data stored in the first blockchain and the verification information stored in the second blockchain. Correspondingly, as shown in fig. 5, step S102 includes:

step S102-6, acquiring service data to be verified and a first hash value associated with the service data from a first block chain; the first hash value is calculated on the basis of the service data and the additional data when the second user stores the service data to be stored to the first block chain in advance through the first block chain link point in the first block chain;

specifically, when the first block chain is a public chain, all users have authority to view data in the first block chain, so that the first user can directly obtain service data to be verified and a first hash value stored corresponding to the service data to be verified from the first block chain through the terminal device of the first user; when the first blockchain is a federation chain, the public range of the federation chain can be preset by members of the federation chain, for example, when a certain group is a member of the federation chain, whether a user in the group deploys a federation chain node or not can be set, the user has the authority to view data on the federation chain, and therefore when the first user is a user with the authority to view data, the service data on the first blockchain can be verified.

Correspondingly, as shown in fig. 5, step S104 includes:

step S104-6, the acquired first hash value is used as index information of the verification information to be inquired, and a verification information inquiry request is sent to a second block chain link point in a second block chain according to the index information, so that the second block chain link point inquires the associated verification information from the second block chain according to the index information;

and step S104-8, receiving the verification information sent by the second blockchain node.

The verification information comprises a second hash value obtained by calculating the service data to be stored by the terminal equipment of the second user according to a first preset algorithm in advance;

correspondingly, as shown in fig. 5, step S106 includes:

step S106-10, calculating a fourth hash value of the acquired service data according to a first preset algorithm, determining whether the fourth hash value is consistent with a second hash value included in the verification information, and if so, determining that the service data passes the verification.

Therefore, when the first user needs to verify the service data of the second user, the terminal equipment of the first user can directly acquire the service data of the second user and the corresponding first hash value from the first block chain, acquire corresponding verification information from the second block chain according to the first hash value, and verify the acquired service data of the second user according to the acquired verification information; therefore, for the first user, the terminal device does not need to be deployed as a node device to join the block chain, the terminal device of the first user does not need to participate in consensus verification, and all data in the block chain are not needed to be stored in the terminal device of the first user, so that the verification requirement of the first user on the service data of the second user is met on the basis of reducing the operation of the terminal device of the first user and reducing resource consumption.

It should be noted that, the first user may deploy its terminal device as a node in the second blockchain, and correspondingly, step S102 includes: acquiring verification information of service data from data stored in terminal equipment; even if the service data is verified by the terminal device of the first user only by storing the verification information and the index information in the form of the hash value, compared with the case of storing the full amount of service data, the amount of the stored data is greatly reduced, so that the requirement on the storage space is reduced, and the resource consumption is reduced.

In the present specification, the integrity of the service data can be verified by the above manner of storing the service data of the user by using the first blockchain and storing the verification information of the service data in the first blockchain by using the second blockchain; it can be considered that, by adopting the double-chain data storage manner, the scheme of the present specification may also be applied to a data verification manner such as validity of service data, and details are not described herein.

In one or more embodiments of the present description, by saving the service data in the first block chain in advance, and saving the verification information of the service data in the second block chain, the terminal device of the first user can respond to the data verification request of the first user, obtain the service data to be verified from the first block chain, obtain the verification information of the service data from the second block chain, and verify the service data according to the obtained verification information. Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data which the first user wants to verify, and therefore, the verification requirement of the first user on the service data is met on the basis that excessive resources of the first user are not occupied.

specifically, the service data and the additional data are calculated according to a second preset algorithm to obtain a first hash value; in practical application, the additional data may be set according to requirements, such as a receiving time of receiving the first data storage request, a block identifier of a block storing the service data, and the like.

Step S200-6, storing the first hash value and the business data into a first block chain in an associated manner;

and step S200-8, sending the first hash value to the terminal equipment so that the first user inquires the service data according to the first hash value.

Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data in the first block chain, and therefore, the requirement of the first user on verification of the service data is met on the basis that excessive resources of the first user are not occupied.

step S300-4, calculating a third hash value according to the first hash value and the second hash value;

specifically, the first hash value and the second hash value are calculated according to a third preset algorithm to obtain a third hash value; the third preset algorithm can be set as required in practical application.

Step S300-6, the first hash value, the second hash value and the third hash value are stored in a second block chain in an associated mode;

and step S300-8, sending the third hash value to the terminal equipment.

By calculating the third hash value and sending the third hash value to the terminal device of the first user, on one hand, the user knows that the verification information is successfully stored, and on the other hand, when the first user needs to acquire the verification information, the corresponding verification information can be quickly and accurately acquired based on the third hash value.

Since the first hash value and the third hash value are stored in the terminal device of the first user, and the first hash value and the third hash value are also stored in the second block chain, in practical application, when the first user needs to verify the service data of the first user, the first hash value may be used as the index information of the verification information, the third hash value may be used as the index information of the verification information, or the first hash value and the third hash value may be used together as the index information of the verification information. Specifically, when the index information includes the third hash value, step S304 includes:

inquiring the associated first hash value and second hash value from the second block chain according to the third hash value to obtain verification information;

when the index information includes the first hash value, step S304 includes:

inquiring a related second hash value from a second block chain according to the first hash value to obtain verification information;

when the index information includes the first hash value and the third hash value, step S304 includes:

and inquiring the associated second hash value from the second block chain according to the first hash value and the third hash value to obtain verification information.

Therefore, when the first user needs to verify the service data of the first user, the terminal device can respond to the data verification request of the first user and send a verification information inquiry request to the second block link node according to the stored first hash value and/or the stored second hash value, and the second block link node can search the verification information of the service data of the first user according to the first hash value and/or the second hash value.

Further, when the first user needs to verify the service data of the second user, a verification information query request may be sent to the second block link point based on the first hash value obtained from the first block link to obtain corresponding verification information; the index information includes a first hash value, and the first hash value is a hash value calculated by a first block link point based on the service data and the additional data when the service data to be stored is stored in the first block link by a second user through the first block link point in the first block link in advance; correspondingly, step S304 includes:

inquiring a related second hash value from a second block chain according to the first hash value to obtain verification information; the second hash value is a hash value calculated by the terminal device of the second user based on the service data in the first block chain.

Specifically, when a second user sends a first data storage request to a first block chain node in a first block chain through terminal equipment of the second user, the first block chain node acquires service data from the first data storage request, calculates the acquired service data and additional data according to a second preset algorithm to obtain a first hash value, stores the first hash value and the service data in association with each other in the first block chain, and sends the first hash value to the terminal equipment of the second user; when receiving the first hash value, the terminal equipment of the second user calculates the service data to be stored included in the first data storage request according to a first preset algorithm to obtain a second hash value, and sends a second data storage request to the second block chain node according to the first hash value and the second hash value; when the second block chain node receives a second data storage request sent by the terminal equipment of a second user, calculating the first hash value and the second hash value according to a third preset algorithm to obtain a third hash value, and storing the first hash value, the second hash value and the third hash value into a second block chain in an associated manner; therefore, when the second block link point receives the verification information query request sent by the terminal device of the first user, the corresponding verification information can be queried based on the index information included in the verification information query request, namely the first hash value calculated by the first block link point based on the service data to be stored of the second user and the additional data, and the queried verification information is sent to the terminal device of the first user, so that the terminal device of the first user can verify the service data of the second user according to the verification information.

Thus, for the first user, it does not need to deploy a node device to become a node in the blockchain, nor participate in consensus verification, and does not need to store all data in the blockchain; even in this way, the first user can still verify the service data in the first block chain, and therefore, the requirement of the first user on verification of the service data is met on the basis that excessive resources of the first user are not occupied.

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 Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (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: ARC 625D, 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.
