Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a page access method of a decentralizing application according to an embodiment of the present application. The decentralizing application (Decentralized Application, DAPP) refers to an application running on a distributed network (blockchain) that performs decentralizing operations by nodes in the blockchain. In FIG. 1, the de-centralized application 10 is running on top of the blockchain 20, wherein nodes 20a, 20b, 20c, and 20d are each part of nodes in the blockchain 20, and any of nodes 20a, 20b, 20c, and 20d may access or otherwise operate on the de-centralized application 10. The nodes 20a, 20b, 20c and 20d may be devices accessing the blockchain 20, including, but not limited to, mobile terminals, notebook computers, tablet computers, wearable portable devices, and the like. The nodes 20a, 20b, 20c and 20d may also be users accessing the blockchain 20 through the above devices, and may be specifically determined according to the actual application scenario, which is not limited herein. When the node 20a is a first user node logging into the decentralized application 10, and when the node 20 needs to share a target page, the decentralized application 10 may receive a target page sharing request sent by the node 20a, where the target page may be any page of the decentralized application 10, such as a first page, a setup page, etc. of the decentralized application 10, which may be specifically determined according to an actual application scenario, and is not limited herein. After receiving the target page sharing request, the decentralized application 10 may send the target page sharing request to the consensus node in the blockchain 20 so that the consensus node determines whether the node 20a has the sharing authority of the target page. The common nodes in the blockchain 20 may be the nodes 20b and 20c in fig. 1, or may be determined according to the actual application scenario, which is not limited herein.

When the consensus node of the blockchain 20 determines that the node 20a has the sharing right of the target page, the decentralized application 10 may determine the blockchain address of the page information of the target page in the blockchain 20 according to the page identifier of the target page carried by the target page sharing request sent by the node 20a, and send the blockchain address to the node 20a so that the node 20a signs the blockchain address according to the private key thereof to obtain the encrypted blockchain address. Further, the decentralized application 10 may obtain the encrypted blockchain address sent by the node 20a, and generate a two-dimensional code according to the encrypted blockchain address to broadcast the two-dimensional code in the blockchain 20, so that other user nodes in the blockchain 20, such as the node 20b, access the target page of the decentralized application 10 according to the two-dimensional code.

Referring to fig. 2, fig. 2 is a flow chart of a page access method of a decentralizing application according to an embodiment of the present application. The page access method of the decentralizing application shown in fig. 2 may include the following steps S201 to S204.

S201, the decentralizing application receives a target page sharing request sent by a first user node.

In some possible embodiments, the first user node may be any terminal device accessing to the blockchain, such as a notebook computer, a mobile terminal, a portable device, or the like, or may be a user accessing to the decentralized application according to the above device, which may be specifically determined according to an actual application scenario, and is not limited herein. The target page may be any page of the decentralized application, such as a commodity detail page of the shopping application, or a video playing page of the video application, which may be specifically determined according to an actual application scenario, and is not limited herein. When the first user node needs to share the target page of the decentralizing application so that other nodes access the target page, the first user node can send a target page sharing request to the decentralizing application, and at the moment, the decentralizing application can receive the target page sharing request sent by the first user node so that other nodes access the target page. The first user node needs to carry the page identifier of the target page or the application identifier of the decentralizing application when sending the target page sharing request to the blockchain, so that the decentralizing application running in the blockchain can identify the target page sharing request sent by the first user node.

S202, the decentralizing application sends a target page sharing request to a consensus node in the blockchain, so that the consensus node determines whether the first user node has the sharing authority of the target page.

In some possible embodiments, after receiving the target page sharing request sent by the first user node, the decentralizing application may further determine whether the first user node has the sharing authority of the target page, thereby improving the application security of the decentralizing application. Specifically, the decentralized application may send a target page sharing request to consensus nodes in the blockchain to enable each consensus node in the blockchain to respectively verify whether the first user node has the sharing authority of the target page. Each consensus node can acquire the node information of the first user node and the page identifier carried by the target page sharing request, determine the authority level of the target page according to the page identifier, determine the authority level of the first user node according to the node information of the first user node, and when the authority level of the first user node is not lower than the authority level corresponding to the target page, the consensus node can determine that the first user node has the sharing authority of the target page. Optionally, the consensus node may determine a permission node list corresponding to the target page according to the page identifier, further determine whether the first user node is in the permission node list corresponding to the target page according to the node information of the first user node, and when the first user node is in the permission node list corresponding to the target page, the consensus node may determine that the first user node has the sharing permission of the target page. Optionally, the consensus node may further verify whether the first user node is a preset node (such as an administrator node, an application maintenance node, etc.) according to the node information of the first user node, and determine that the first user node has the sharing authority of the target page when the first user node is the preset node. It should be specifically noted that, the specific implementation manner of determining whether the first user node has the sharing authority of the target page by using the formula node may be determined according to an actual application scenario, which is not limited herein.

In some possible embodiments, after sending the target page sharing request to the consensus nodes, the decentralized application further determines that the first user node has sharing authority, and when the number of the consensus nodes determined that the first user node has sharing authority exceeds a certain data amount (e.g., more than half) of the number of all user nodes in the blockchain, the decentralized application may determine that the first user node has sharing authority of the target page. Optionally, the decentralizing application may determine whether a preset consensus node in all the consensus nodes determines that the first user node has the sharing authority of the target page, and when the preset consensus node has the sharing authority of the target application, the decentralizing application may determine that the first user node has the sharing authority of the target application.

And S203, when the first user node has the sharing right, the decentralizing application determines the blockchain address of the page information of the target page in the blockchain according to the page identification, and sends the blockchain address to the first user node so that the first user node signs the blockchain address according to the private key of the first user node to obtain the encrypted blockchain address.

In some possible embodiments, when the first user node has the sharing right of the target page, the decentralizing application may determine, according to the page identifier carried by the target page sharing request, a blockchain address of the page information of the target page in the blockchain. Specifically, the de-centering application may determine a target block marked by the page identifier from the blockchain, or the de-centering application may determine a target block height corresponding to the page identifier and determine a block corresponding to the target block height as the target block, and further, the de-centering application may determine the target block height of the target block as the blockchain address of the page information. Optionally, the decentralizing application may call an intelligent contract corresponding to the page identifier, and further determine the blockchain address of the page information of the target page by executing the intelligent contract. It should be specifically noted that, the above blockchain address may include, in addition to the target block height, a specific storage location of the page information of the target page in the target block corresponding to the target block height, which may be specifically determined according to the actual application scenario, and is not limited herein.

In some possible embodiments, to further improve the security of the decentralizing application, after determining that the page information of the target page is the blockchain address in the blockchain, the decentralizing application may send the blockchain address to the first user node to enable the first user node to sign the blockchain address according to the private key of the first user node to obtain the encrypted blockchain address. Specifically, the decentralizing application sends the blockchain address to the first user node, so that the first user node further signs the blockchain address by using a private key of the first user node to obtain an encrypted blockchain address. Optionally, the decentralizing application may further directly obtain a private key of the first user node, and further sign the blockchain address according to the private key of the first user node after determining that the page information is in the blockchain address to obtain a final encrypted blockchain address.

Optionally, in order to further improve the security of the blockchain address, the decentralizing application may further perform hash computation on the blockchain address to obtain a digest of the blockchain address, and sign the digest with a private key of the first user node to obtain a digital signature of the blockchain address, so that the blockchain address and the digital signature of the blockchain address are regarded as corresponding encrypted blockchain addresses. Referring to fig. 3, fig. 3 is a schematic diagram of a scenario for determining an encrypted blockchain address according to an embodiment of the present application. In fig. 3, assume that the digest of the blockchain address obtained after the hash calculation of the blockchain address by the decentralizing application is 1000100, and the digest 1000100 is signed by the decentralizing application using the private key of the first user node to obtain 0010101. Assuming that the blockchain address is abcd at this time, the decentric application can consider abcd and 0010101 as the corresponding encrypted blockchain addresses.

The application of decentralization can be performed by adopting an information abstraction algorithm when hash calculation is performed on the block chain address. Among them, the above information Digest Algorithm includes, but is not limited to, cyclic redundancy check-8 (Cyclic Redundancy Check-8, CRC 8), cyclic redundancy check-16 (Cyclic Redundancy Check-16, CRC 16), cyclic redundancy check-32 (Cyclic Redundancy Check-32, CRC 32), information Digest Algorithm version 2 (Message-Digest Algorithm 2, MD2), information Digest Algorithm version 4 (Message-Digest Algorithm 4, MD4), information Digest Algorithm version 5 (Message-Digest Algorithm 5, MD5), secure hash Algorithm 1 (Secure Hash Algorithm, SHA 1), secure hash Algorithm 256 (Secure Hash Algorithm, SHA 256), secure hash Algorithm 384 (Secure Hash Algorithm, SHA 384), secure hash Algorithm 512 (Secure Hash Algorithm, SHA 512), RACE original integrity check Message Digest Algorithm (RACE INTEGRITY PRIMITIVES Evaluation MESSAGE DIGEST, RIPEMD), PANAMA, TIAdger and ler-3 algorithms, etc., and may be specifically determined based on the actual application scenario without limitation. Wherein, the length, the expression form and the like of the abstracts obtained by different information abstracting algorithms are different. For example, a hash value expressed in 8-bit hexadecimal numbers can be obtained based on CRC32, a hash value expressed in 32-bit hexadecimal numbers can be obtained based on MD5, and a hash value of 32 bytes (256 bits) in length can be obtained based on SHA 256.

For example, referring to fig. 4, fig. 4 is a schematic diagram of a scenario for performing hash computation on a blockchain address according to an embodiment of the present application. As shown in fig. 4, the blockchain address determined by the decentralizing application is A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa, and at this time, if the decentralizing application performs hash computation on the blockchain address based on MD5, the corresponding digest obtained by the decentralizing application is d33d49bc2379e65ac7e7c9edd0a80a48.

S204, the decentralizing application acquires an encrypted blockchain address, a two-dimensional code is generated according to the encrypted blockchain address, and the two-dimensional code is broadcasted in the blockchain so that the second user node accesses the target page according to the two-dimensional code.

In the embodiment of the application, after the decentralizing application signs the blockchain address to obtain the encrypted blockchain address at the first user node, the decentralizing application obtains the encrypted blockchain address sent by the first user node and generates the two-dimensional code according to the encrypted blockchain address, and the decentralizing application can broadcast the two-dimensional code in the blockchain to enable the second user node to access the target page according to the two-dimensional code. The specific method for generating the two-dimensional code by the application of decentralization according to the encrypted blockchain address can be seen in fig. 5. Fig. 5 is a schematic flow chart of generating a two-dimensional code according to an embodiment of the present application. The method for generating the two-dimensional code provided in fig. 5 may include the following steps S2041 to S2043.

S2041, the decentralization application determines an index value of each character of the encryption blockchain address, and determines a data code of the encryption blockchain address according to the index value of each character.

In the embodiment of the present application, for the encryption blockchain address, each character in the encryption blockchain address corresponds to a fixed index value, wherein for the digits 0-9, the index value corresponding to each character is respectively 0-9, for the english letters a-Z, the index value corresponding to each character is respectively 10-35, the index value corresponding to the "+" is 37, the index value corresponding to the "%" is 38, the index value corresponding to the "x" is 39, the index value corresponding to the "+" is 40, and the index value corresponding to the "-" is 41. When the encryption block chain address is encoded, each character of the encryption block chain address is firstly converted into a corresponding index value, every two characters are divided into a group, and then the group is converted into a binary result of 11 bits. For one character of the drop list, the decentralization application may convert it to a 6bits binary result. Wherein, since the encoding of the encrypted blockchain address belongs to character encoding, the character encoding flag is 0010. It should be noted that, after obtaining the binary result corresponding to each group of characters, the number of the characters of the encrypted blockchain address needs to be converted into the corresponding binary according to the preset two-dimensional code version (the two-dimensional code version to be generated or generated by default), and then the character codes of the encrypted blockchain address are obtained according to the three-segment character strings. For character encoding, two-dimensional code versions 1-9 correspond to 10bits, two-dimensional code versions 10-26 correspond to 11bits, and two-dimensional code versions 27-40 correspond to 13bits.

Referring to fig. 6, fig. 6 is a schematic view of a scenario of a method for determining character encoding according to an embodiment of the present application. In fig. 6, assume that the preset two-dimensional code version is 1, the encrypted blockchain address is AE-86, and at this time, the index values corresponding to the encrypted blockchain address are (10,14,41,8,6). Further, the application of decentralization can group the obtained 5 characters two by two to obtain (10, 14), (41,8), (6), and further convert each group of characters into 11bits binary system. Wherein, (10, 14) can be converted into 45 binary system to obtain 464, and then the 464 is converted into 11bits binary system: 00111010000, converting (41,8) into 45 binary to obtain 1853, and converting 1853 into 11bits binary: 11100111101. for (6), its corresponding 45 bins are still 6, and then converted to 6bits of binary: 000110. at this point, the three binary results may be concatenated to yield 0011101000011100111101000110. Further, when the two-dimensional code version is 1, the number of characters 5 of the encrypted blockchain address needs to be converted into 9bits binary: 000000101, since the character encoding flag corresponding to the encrypted blockchain address is 0010, the character encoding of the encrypted blockchain address is obtained before the character encoding flag and the 9bits binary are added to 0011101000011100111101 000110: 00100000001010011101000011100111101000110.

Further, after the character encoding of the encrypted blockchain address is obtained, an end symbol (continuous 40 values) needs to be added to the end of the character encoding. Wherein if the number of character encoding bits is not a multiple of 8 in addition, it is also necessary to add a sufficient value of 0 after character encoding until a multiple of 8 is reached. On the other hand, for different two-dimensional codes with different error correction levels, each error correction level corresponds to different maximum bits restriction under different versions, so when the character coding plus the ending symbol still does not reach the maximum bits restriction corresponding to the corresponding error correction level, the padding symbol is needed to be added at the end of the coding. Wherein the patch content is repeated for two bytes: 11101100 and 00010001. Taking the example of character codes 00100000 01101010 00101101 00111011 00101001 01111001 01001000 10101101 11101000 00110110 000, there are 83bits in total, so the multiples of 8 are two more bits apart, so the last 5 0's (ending symbol) are added to obtain 00100000 01101010 00101101 00111011 00101001 01111001 01001000 10101101 11101000 00110110 00000000. For the H error correction level of the two-dimensional code version 1, 26 codewords are required, namely 104bits. Now, the ending symbol complemented with 0 is already 88bits, so that 16bits are also required to be complemented. The padded code is ：00100000 01101010 00101101 0011101100101001 01111001 01001000 10101101 11101000 00110110 00000000 11101100 00010001., namely the padded code is the data code of the encrypted block chain address.

S2042, the decentralizing application determines an error correction level corresponding to the decentralizing application, and error correction codes of the data codes are determined according to the error correction level.

In the embodiment of the application, the two-dimensional code has four error correction levels in total, wherein the error correction level L can be corrected by 7% of the code words, the error correction level M can be corrected by 15% of the code words, the error correction level Q can be corrected by 25% of the code words, and the error correction level H can be corrected by 30% of the code words. Specifically, the number of error correction blocks and the number of error correction block code words of the data coding can be determined according to the two-dimensional code version and the error correction level corresponding to the decentralization application, wherein the number of error correction blocks represents the number of error correction blocks to be divided, and the number of error correction block code words represents the number of codewords in each block, namely, the number of bytes.

Taking two-dimensional code version 5 and error correction level as an example, four blocks (a group of two blocks for each of uplink and downlink), wherein the number of error correction blocks in the first group is 2, each block in the group has 33 codewords, 11 data codes, 11×2=22 error correction codes, the number of error correction blocks in the first group is 2, and each block in the group has 34 codewords, 12 data codes, 11×2=22 error correction codes. The use of binary makes the table too large, and therefore turns into decimal numbers ranging from 0 to 255. Wherein each block of group 1 has 11 data codes and 22 error correction codes; each block of group 2 has 12 data codes and 22 error correction codes. The error correction code of the data coding is mainly implemented by a reed-solomon error correction algorithm, which is not described herein. Based on the reed-solomon error correction algorithm, for the first set of first block data 67 85 70 134 87 38 85 194 119 50 6, the error correction code corresponding to that block is 199 11 45 115 247 241 223 229 248 154 117 236 38 6 50 17 7 236 213 87 148 235.

S2043, the two-dimensional code is generated by the decentralization application according to the data coding and the error correction coding.

In some possible embodiments, when the application of decentering is used to generate a two-dimensional code, it is necessary to first draw a positioning pattern on three corners of the two-dimensional code and further draw a pattern for the positioning pattern. The positioning pattern is 7*7 matrix, the pattern is 5*5 matrix, and the specific drawing method can be determined according to the actual application scene without limitation. Further, the application of decentering requires drawing a timing pattern of the two-dimensional code, wherein the timing pattern is two lines connecting three positioning patterns, and format information is added around the positioning patterns. Because the number of the positioning patterns is fixed to 3 and the size is fixed, the format information is also information for fixing 15bits, and the data in 5bits are arranged according to the sequence of the data bits in 5bits and the error correction bits in 10 bits; the data bits occupy 5bits: wherein 2bits are used to represent the error correction level used and 3bits are used to represent the Mask (Mask) class used; error correction bits account for 10bits: calculated mainly by BCH Code. To reduce the difficulty of image recognition after scanning, finally, an exclusive or XOR operation is required to be performed on 15bits and 101010000010010. Because there may be too many 0 values (e.g., error correction level of 00, mask of 000) in the original format information, making the format information all white would increase the difficulty of analyzing the image. Further, the region centering application can fill the obtained data codes and error correction codes into the rest part of the two-dimensional code, and the specific filling mode can be determined according to the actual application scene without limitation. For example, for a conventional module in a two-dimensional code, the order of arrangement of the conventional module (i.e., 8bits of data is all within two columns) should be from right to left, regardless of whether the filling direction of the data (data encoding and error correcting code) is up or down. Alternatively, the most significant bit (i.e., the 7 th bit) of each codeword should be placed in the first available bit. For the direction of upward fill, the most significant bit should occupy the lower right corner of the module; the most significant bit occupies the upper right of the module in the downward filling direction. If the previous module ends inside the column of the right module, the module becomes an irregular module and the highest position should be in the upper right corner when the original filling direction is upward, as compared to the conventional module, and becomes the lower left corner at this time. Alternatively, when two columns of a module encounter a horizontal boundary of an alignment pattern or timing pattern at the same time, it will continue above or below the pattern. Alternatively, when the module reaches the upper and lower boundaries of the region (including the upper and lower boundaries of the two-dimensional code, format information, version information, or separator), any remaining bits in the codeword will be filled in the next column to the left, and the filling direction is reversed. Alternatively, when the right column of the module encounters an alignment pattern, or encounters an area occupied by version information, the data bits continue to fill along a column beside the alignment pattern or version information and form an irregular module. If both next columns are available before the end of the current module fill, the most significant bit of the next codeword should be placed in the single column.

In some possible embodiments, after the two-dimensional code is generated according to the encrypted blockchain address, the decentralizing application may send the two-dimensional code and the public key of the first user node to the consensus nodes, so that each consensus node verifies whether the two-dimensional code matches the blockchain address obtained by the decentralizing application, and determines whether other nodes can access the target page through the two-dimensional code. Specifically, each consensus node may identify the two-dimensional code to obtain an encrypted blockchain address, decrypt the encrypted blockchain address by using the public key to obtain an unencrypted blockchain address and match the unencrypted blockchain address with the original blockchain address, if the two-dimensional code and the encrypted blockchain address are identical, it is indicated that the blockchain address obtained according to the two-dimensional code is the blockchain address corresponding to the page information of the target page, and at this time, the decentralizing application may broadcast the two-dimensional code in the blockchain, so that the second user node or other user nodes access the target page according to the two-dimensional code.

Referring to fig. 7, fig. 7 is another flow chart of a page access method of a decentralizing application according to an embodiment of the present application. The page access method of the decentralizing application shown in fig. 7 may include the following steps S701 to S706.

S701, the decentralizing application receives a target page sharing request sent by a first user node.

S702, the decentralizing application sends a target page sharing request to a consensus node in the blockchain, so that the consensus node determines whether the first user node has the sharing authority of the target page.

S703, when the first user node has the sharing right, the decentralizing application determines the blockchain address of the page information of the target page in the blockchain according to the page identification, and sends the blockchain address to the first user node so that the first user node signs the blockchain address according to the private key of the first user node to obtain the encrypted blockchain address.

S704, the decentralizing application acquires an encrypted blockchain address, generates a two-dimensional code according to the encrypted blockchain address, and broadcasts the two-dimensional code in the blockchain so that the second user node accesses the target page according to the two-dimensional code.

In some possible embodiments, the specific implementation manners of the steps S701 to S704 may be referred to the implementation manners shown in steps S201 to S202 in fig. 2, which are not described herein.

And S705, when an access request triggered when the second user node identifies the two-dimension code is received, the decentralizing application acquires the public key of the first user node, and decrypts the encrypted blockchain address according to the public key of the first user node to obtain the blockchain address.

In some possible implementations, the second user node may access the de-centralized application by identifying the two-dimensional code after acquiring the two-dimensional code broadcast in the blockchain. The second user node may directly obtain the two-dimensional code from the blockchain, or may directly identify the two-dimensional code from other nodes where the two-dimensional code has been obtained, for example, directly identify the two-dimensional code displayed by the B device through the a device, or directly identify the two-dimensional code stored in the B device through the a device, etc., where the specific implementation manner may be determined according to the actual application scenario, and the specific implementation manner is not limited herein. The two-dimensional code is obtained by the decentralization application according to the encrypted blockchain address, so that the second user node can only obtain the encrypted blockchain address when identifying the two-dimensional code, and can not obtain the unencrypted blockchain address through the encrypted blockchain address so as to access the target page through the unencrypted blockchain address. The second user node needs to send an access request to the decentralizing application when identifying the two-dimensional code to cause the decentralizing application to send the unencrypted blockchain address to the second user node. Specifically, when the decentralizing application receives an access request sent by the second user node, the decentralizing application may acquire the public key of the first user node to decrypt the encrypted blockchain address to obtain an unencrypted blockchain address.

S706, the decentralizing application sends the blockchain address to the second user node so that the second user node can acquire the page information of the target page according to the blockchain address and access the target page according to the page information.

In some possible implementations, after the un-encrypted blockchain address is obtained, the application may send the blockchain address to the second user node, so that the second user node may retrieve the page information of the target page of the un-centralized application from the blockchain address by invoking a smart contract. Further, the second user node can construct the target page according to the page information of the target page, so that access to the target page of the decentralizing application is realized. Optionally, the decentralizing application may also directly obtain the page information of the target page according to the blockchain address, and send the page information to the second user node, so that the second user node directly constructs the target page according to the page information, where the specific implementation manner may be determined according to the actual application scenario, and is not limited herein.

In some possible embodiments, the page information of the target page may include page configuration data of the target page and a target smart contract corresponding to the target page, where the target smart contract user implements various page functions of the target page (such as uploading information, sending a message, etc., which may be specifically determined according to an actual application scenario, and is not limited herein). After the decentralized application receives the access request triggered by the second user node and determines the blockchain address according to the public key of the first user node, the decentralized page can respectively acquire page configuration data and the target intelligent contract from the blockchain according to the blockchain address. At this time, the decentralizing application may configure the target page according to the page configuration data, and re-execute the target smart contract to determine whether the target smart contract matches the target page, i.e., verify whether the page function represented by the target smart contract is the page function corresponding to the target page. If the target intelligent contract is matched with the target page, namely the page function carried by the target intelligent contract is the page function corresponding to the target page, the decentralizing application sends an access permission notification to the second user node so that the second user builds the target page according to the page configuration data to realize the access to the target page.

In some possible embodiments, since the two-dimensional code is generated by the encrypted blockchain address and the encrypted blockchain address is encrypted by the private key of the first user node, after the second user node accesses the target page according to the two-dimensional code, the decentralized application may send access event information to the first user node to inform the second user that the target page is accessed by the two-dimensional code obtained by the page sharing request. On the other hand, after receiving the access event information sent by the decentralizing application, the first user node may send the corresponding data volume receiving address (such as an account, a wallet address, etc.) and the node information of the first user node to the decentralizing application, so that the decentralizing application may determine, according to the node information of the first user node, a preset data volume determining manner satisfied by the first user node to determine the transfer data volume that the first user node should receive, and send the transfer data volume to the data volume receiving address. In short, after the user b accesses a certain page of the decentralizing application through the two-dimensional code generated by the target page sharing request of the user a, the decentralizing application may award the user a certain amount of rewards to encourage the user a to share the decentralizing application or a certain page of the decentralizing application with other users for multiple times.
