Based on the above description of the embodiment of the block chain structure, the embodiment of the present invention provides a block chain construction method, which can be applied to the block chain structure shown in fig. 1, and can be specifically executed by the first terminal shown in fig. 1. Referring to fig. 2, the block chain construction process may include the following steps S201 to S203:
s201, the first terminal responds to the block chain creating operation to generate a block chain, and the first terminal is determined to be a node in the block chain.
In this embodiment of the present invention, the first terminal may receive a block chain creation operation input by a user, and generate a block chain in response to the creation operation, where the first terminal is to be a node in the generated block chain.
In a specific implementation, the first terminal may allocate an independent storage space for the generated blockchain in the built-in storage space, so as to prevent the content stored in the blockchain from being mixed with the local content of the first terminal, and enhance the independence of the content stored in the blockchain. Specifically, the first terminal may create a created block of the block chain in the independent storage space to generate the block chain.
In one implementation, after the first terminal generates the block chain, corresponding port information may be generated based on an address of the block chain, where the port information includes a port number, a two-dimensional code, a link, and the like, so that other terminals may access the block chain according to the port information.
In an implementation manner, after the first terminal generates the block chain, it may also receive a configuration operation input by a user, and determine port information for the block chain according to the configuration operation, so that other terminals access the block chain according to the port information.
S202, the first terminal receives a block chain adding request sent by the second terminal, and the adding request carries verification information required by adding the block chain.
In the embodiment of the invention, after the first terminal generates the block chain, the port information of the block chain is broadcasted, wherein the port information comprises at least one of a port number, a two-dimensional code and a link, so that the second terminal accesses the block chain generated by the first terminal according to the port.
In an implementation manner, the first terminal may broadcast the port information through WIFI, and specifically, the first terminal may broadcast the port information through WIFI, that is, the first terminal transmits the port information to a user connected to the same WIFI, for example, the port information is a two-dimensional code, the first terminal may generate a two-dimensional code corresponding to a block chain after generating the block chain, and send the two-dimensional code to a second terminal connected to the same WIFI, and the second terminal may access an address of the block chain in a manner of recognizing the two-dimensional code, and send a block chain adding request to the first terminal.
In one implementation, the first terminal may also receive a selection operation input by a user, where the selection operation includes a second terminal to which the port information needs to be sent, and the first terminal may send the port information to the second terminal corresponding to the selection operation through a network, so that the second terminal may access the block chain according to the port information.
Further, after receiving the port information, the second terminal may send a block chain joining request to the first terminal according to the received port information, where the block chain joining request carries verification information required for joining the block chain. In one implementation, the port information is a two-dimensional code, and the second terminal may identify the two-dimensional code after receiving the two-dimensional code and access the generated blockchain to send a blockchain join request to the first terminal, or the port information is a link, and the second terminal may access the generated blockchain based on an address in the link to send a blockchain join request to the first terminal after receiving the link. Or, the port information is a port number, and the second terminal may access the generated blockchain by inputting the port number in a blockchain access function built in the terminal after receiving the port number, so as to send a blockchain join request to the first terminal. In an implementation manner, the same port number may also be agreed in advance by a user using the first terminal and a user using the second terminal, and after the first terminal generates the block chain according to the port number, the user of the second terminal inputs the port number in the second terminal, so that the second terminal accesses the block chain generated by the first terminal, thereby implementing face-to-face establishment of the block chain. The blockchain access function may be inserted into any Application (APP), such as a social APP, a video APP, and a music APP. In specific implementation, for different types of APPs, the content stored in the established blockchain may be different, for example, the blockchain established by social APPs may be used to store transaction information, chat information, and the like between users, the blockchain established by video APPs may be used to store videos communicated between users, and the blockchain established by music APPs may be used to store music communicated between users, and in specific implementation, when accessing the APP generated by the first terminal using the blockchain access function in the APP, the second terminal needs to be the same as the APP used by the first terminal to establish the blockchain.
It should be noted that when the second terminal sends the block chain join request to the first terminal, the second terminal also needs to carry check information required for joining the block chain, where the check information may include one or more of request time, request address, and secret key, the request time is the time when the second terminal sends the block chain join request, the request address is the address when the second terminal sends the block chain join request, and the secret key may enter a password required for the block chain.
S203, the first terminal verifies the verification information, and if the verification is passed, the second terminal is determined to be a node in the block chain.
In the embodiment of the invention, after the first terminal receives the verification information, the verification information is verified, and if the verification is passed, the second terminal is added into the block chain.
In an implementation manner, the verification information includes a request time, and the process of the first terminal verifying the verification information may specifically be that the first terminal verifies whether the request time of the block chain join request sent by the second terminal is within a preset time period, and if so, it is determined that the verification information satisfies the verification condition. If not, determining that the verification condition is not met, and ending the process. Specifically, the created blockchain may be set by a user using the first terminal 10 minutes, 1 hour, 1 day, and the like after the blockchain is created in the preset time period. By the method, the port information of the block chain can be time-efficient.
In an implementation manner, the verification information includes a request address, and the process of the first terminal verifying the verification information may specifically be that the first terminal verifies whether a distance between the request address of the block chain joining request sent by the second terminal and the address of the first terminal is smaller than a preset distance, and if so, it is determined that the verification information satisfies the verification condition. If not, determining that the verification condition is not met, and ending the process. By the method, the function of establishing the block chain face to face can be realized, and illegal terminals are prevented from entering the block chain by mistake.
In an implementation manner, the verification information includes a secret key, and the process of the first terminal verifying the verification information may specifically be that the first terminal verifies whether the secret key carried by the block chain joining request sent by the second terminal matches a preset secret key, and if so, it is determined that the verification information satisfies the verification condition. If not, determining that the verification condition is not met, and ending the process. Wherein the preset key may be set by a user using the first terminal after inputting the blockchain creation operation. By the method, the illegal terminal can be prevented from entering the block chain by mistake, and the security characteristic is added to the block chain.
In an implementation manner, the verification information includes a request time and a request address, and the process of verifying the verification information by the first terminal may specifically be that the first terminal verifies whether the request time of the block chain join request sent by the second terminal is within a preset time period, if so, verifies whether a distance between the request address of the block chain join request sent by the second terminal and the address of the first terminal is smaller than a preset distance, and if so, determines that the verification information satisfies the verification condition.
In an implementation manner, the verification information includes request time, a request address and a secret key, and the process of verifying the verification information by the first terminal may specifically be that the first terminal verifies whether the request time of the block chain join request sent by the second terminal is within a preset time period, if so, verifies whether a distance between the request address of the block chain join request sent by the second terminal and the address of the first terminal is smaller than a preset distance, if so, the first terminal verifies whether the secret key carried by the block chain join request sent by the second terminal is matched with the preset secret key, and if so, it is determined that the verification information satisfies the verification condition. By implementing the method, the blockchain can be established face to face, and the confidentiality characteristic is added for adding and deleting the nodes of the blockchain.
Further, after at least one second terminal is verified as a node in the block chain, the first terminal may obtain transaction data between the nodes of the block chain, and package the transaction data to obtain a first block; the first terminal links the first block with the created block to increase information stored by the block chain. Referring to the completed block-link structure shown in fig. 1, the block-link structure is used for data sharing between nodes, and the block-link structure may include 101 corresponding to a first terminal and nodes 102, 103, and 104 corresponding to a plurality of second terminals, respectively. Each node may receive input information during normal operation and maintain shared data within the block chain structure based on the received input information. In order to ensure the information intercommunication in the block chain structure, information connection can exist between each node in the block chain structure, and the nodes can transmit information through the information connection. For example, when an arbitrary node in the block chain structure receives input information, other nodes in the block chain structure acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored in all the nodes in the block chain structure are consistent.
Each node in the block chain structure has a node identifier corresponding to the node identifier, and each node in the block chain structure may store the node identifiers of other nodes in the block chain structure, so that the generated block is broadcast to other nodes in the block chain structure according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node.
Each node in the block chain structure stores one identical block chain. The block chain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
When each block in the block chain is generated, when a node where the block chain is located receives input information, the input information is verified, after the verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node of the block chain respectively sends the newly generated blocks to other nodes in the block chain structure according to the node identifications of the other nodes in the block chain structure, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added into the block chain stored in the newly generated blocks after the verification is finished.
In the embodiment of the invention, a first terminal responds to a block chain creating operation to generate a block chain, and determines the first terminal as a node in the block chain; a first terminal receives a block chain adding request sent by a second terminal, wherein the adding request carries verification information required by adding a block chain; and the first terminal verifies the verification information, and if the verification is passed, the second terminal is determined as a node in the block chain. By implementing the method, the block chain can be conveniently constructed, and the practicability of the block chain application is improved.
Based on the above description of the embodiment of the block chain structure and the block chain construction method, the embodiment of the present invention provides another block chain construction method, which can be applied to the block chain structure shown in fig. 1, and can be specifically executed by the first terminal shown in fig. 1. Referring to fig. 3, the block chain construction process may include the following steps S301 to S306:
s301, the first terminal responds to the block chain creating operation to generate a block chain, and the first terminal is determined to be a node in the block chain.
In this embodiment of the present invention, the first terminal may receive a block chain creation operation input by a user, and generate a block chain in response to the creation operation, where the first terminal is to be a node in the generated block chain.
In a specific implementation, the first terminal may allocate an independent storage space for the generated blockchain in the built-in storage space, so as to prevent the content stored in the blockchain from being mixed with the local content of the first terminal, and enhance the independence of the content stored in the blockchain. Specifically, the first terminal may create a created block of the block chain in the independent storage space to generate the block chain. As shown in fig. 4, a user may input a click operation to a "blockchain creation" function built in the music APP in the first terminal, and then a blockchain may be generated, where the blockchain may be specifically used to store transaction data, access data, and the like of the music category.
