Based on the above description of the embodiment of the blockchain structure, the embodiment of the present invention provides a blockchain construction method, which can be applied to the blockchain structure shown in fig. 1, and specifically can be executed by the first terminal shown in fig. 1. Referring to fig. 2, the blockchain construction process may include the following steps S201-S203:
s201, the first terminal responds to the blockchain creation operation to generate a blockchain, and the first terminal is determined to be a node in the blockchain.
In the embodiment of the invention, the first terminal can receive the block chain creation operation input by the user, and respond to the creation operation to generate the block chain, and the first terminal is used as a node in the generated block chain.
In a specific implementation, the first terminal can 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 an creation block of the blockchain in the independent storage space to generate the blockchain.
In one implementation, after the first terminal generates the blockchain, the first terminal may generate corresponding port information based on the address of the blockchain, where the port information includes a port number, a two-dimensional code, a link, and so on, so that other terminals may access the blockchain according to the port information.
In one implementation, after the first terminal generates the blockchain, the first terminal may also receive a configuration operation input by a user, and determine port information for the blockchain according to the configuration operation, so that other terminals access the blockchain according to the port information.
S202, the first terminal receives a blockchain joining request sent by the second terminal, wherein the joining request carries verification information required for joining the blockchain.
In the embodiment of the invention, after the first terminal generates the blockchain, the port information of the blockchain 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 blockchain generated by the first terminal according to the port.
In one implementation manner, the first terminal may broadcast the port information through WIFI, 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, then the first terminal may generate a two-dimensional code corresponding to the blockchain after generating the blockchain, 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 blockchain by identifying the two-dimensional code, and send a blockchain joining request to the first terminal.
In one implementation manner, the first terminal may also receive a selection operation input by the user, where the selection operation includes a second terminal to which 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 the network, so that the second terminal may access the blockchain according to the port information.
Further, after receiving the port information, the second terminal may send a blockchain joining request to the first terminal according to the received port information, where the blockchain joining request carries verification information required for joining the blockchain. In one implementation, if the port information is a two-dimensional code, the second terminal may identify the two-dimensional code after receiving the two-dimensional code and access the generated blockchain to send a blockchain joining request to the first terminal, or if the port information is a link, the second terminal may access the generated blockchain based on an address in the link after receiving the link to send a blockchain joining request to the first terminal. Or, if the port information is a port number, 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 joining request to the first terminal. In one implementation, the user using the first terminal and the user using the second terminal may agree on the same port number in advance, and after the first terminal generates the blockchain 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 blockchain generated by the first terminal, and face-to-face establishment of the blockchain is realized. The blockchain access function may be inserted in any Application (APP), such as social APP, video APP, music APP, and the like. In a specific implementation, for different types of APPs, there may be a difference in content stored in a blockchain established by the second terminal, for example, a blockchain established by a social APP may be used to store transaction information between users, etc., a blockchain established by a video APP may be used to store video exchanged between users, etc., a blockchain established by a music APP may be used to store music exchanged between users, etc., and in a specific implementation, when the second terminal accesses the APP generated by the first terminal using a blockchain access function in the APP, the second terminal needs to be the same as the APP used by the first terminal to establish a blockchain.
It should be noted that, when the second terminal sends the blockchain joining request to the first terminal, the second terminal also needs to carry verification information required for joining the blockchain, where the verification information may include one or more of a request time, a request address, and a key, where the request time is a time when the second terminal sends the blockchain joining request, the request address is an address when the second terminal sends the blockchain joining request, and the key may enter a password required by the blockchain.
And 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 blockchain.
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 blockchain.
In one implementation manner, the verification information includes a request time, 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 blockchain joining request sent by the second terminal is within a preset time period, if yes, it is determined that the verification information meets a verification condition. If not, determining that the verification condition is not satisfied, and ending the flow. Wherein, 10 minutes, 1 hour, 1 day, etc. after the creation of the blockchain in the preset time period, the created blockchain may be specifically set by the user using the first terminal. By the method, the port information of the blockchain can be made to be time-efficient.
In one implementation manner, the verification information includes 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 distance between the request address of the blockchain joining request sent by the second terminal and the address of the first terminal is smaller than a preset distance, and if yes, it is determined that the verification information meets the verification condition. If not, determining that the verification condition is not satisfied, and ending the flow. By the mode, the function of establishing the blockchain face to face can be realized, and illegal terminals are prevented from entering the blockchain by mistake.
In one implementation manner, the verification information includes a key, and the process of verifying the verification information by the first terminal may specifically be that the first terminal verifies whether the key carried by the blockchain joining request sent by the second terminal matches with a preset key, and if yes, determines that the verification information meets a verification condition. If not, determining that the verification condition is not satisfied, and ending the flow. 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 blockchain by mistake, and the confidentiality is also added for the blockchain.
In one 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 blockchain joining request sent by the second terminal is within a preset time period, if so, verifies whether the distance between the request address of the blockchain joining request sent by the second terminal and the address of the first terminal is smaller than the preset distance, and if so, determines that the verification information meets the verification condition.
In one implementation manner, the verification information includes a request time, a request address and a secret key, and the verification process of the first terminal on the verification information specifically includes that the first terminal verifies whether the request time of the blockchain addition request sent by the second terminal is within a preset time period, if yes, it verifies whether the distance between the request address of the blockchain addition request sent by the second terminal and the address of the first terminal is smaller than the preset distance, if yes, the first terminal verifies whether the secret key carried by the blockchain addition request sent by the second terminal is matched with the preset secret key, and if yes, it determines that the verification information meets the verification condition. By implementing the method, the face-to-face establishment of the blockchain can be realized, and the confidentiality characteristic is added for node addition and deletion of the blockchain.
Further, after at least one second terminal passes verification as a node in the blockchain, the first terminal can acquire transaction data between nodes of the blockchain and package the transaction data to obtain a first block; the first terminal links the first block with the creation block to increase the information stored in the blockchain. Referring to the completed block chain structure shown in fig. 1, the block chain structure is used for data sharing between nodes, and may include a node 101 corresponding to a first terminal, and a plurality of nodes 102, 103, 104 corresponding to a second terminal respectively. Each node may receive input information while operating normally and maintain shared data within the blockchain structure based on the received input information. In order to ensure the information intercommunication in the block chain structure, information connection can exist between every two nodes in the block chain structure, and the nodes can transmit information through the information connection. For example, when any 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 on all nodes in the block chain structure are consistent.
For each node in the blockchain structure, the node identification corresponding to the node is provided, and each node in the blockchain structure can store the node identifications of other nodes in the blockchain structure so as to broadcast the generated blocks to other nodes in the blockchain structure according to the node identifications of other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol interconnecting between networks) address, or any other information that can be used to identify the node.
Each node in the blockchain structure stores one and the same blockchain. The block chain consists 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 time stamp 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 father 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 father 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 are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.
When each block in the blockchain is generated, when the node where the blockchain is positioned receives input information, checking the input information, after the checking is finished, storing the input information into a memory pool, and updating a hash tree used for recording the input information; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of 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 eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.
Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated blocks to other nodes in the blockchain structure where the newly generated blocks are located according to the node identifications of other nodes in the blockchain structure, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the blockchain stored by the newly generated blocks after the verification is completed.
In the embodiment of the invention, a first terminal responds to a blockchain creation operation to generate a blockchain, and the first terminal is determined to be a node in the blockchain; the first terminal receives a blockchain joining request sent by the second terminal, wherein the joining request carries verification information required for joining the blockchain; and 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. By implementing the method, the blockchain can be conveniently constructed, and the practicability of the blockchain application is improved.
Based on the above description of the blockchain structure and the blockchain construction method embodiment, the embodiment of the present invention provides another blockchain construction method, which can be applied to the blockchain structure shown in fig. 1, and specifically can be executed by the first terminal shown in fig. 1. Referring to fig. 3, the blockchain construction process may include the following steps S301-S306:
s301, the first terminal responds to the blockchain creation operation to generate a blockchain, and the first terminal is determined to be a node in the blockchain.
In the embodiment of the invention, the first terminal can receive the block chain creation operation input by the user, and respond to the creation operation to generate the block chain, and the first terminal is used as a node in the generated block chain.
In a specific implementation, the first terminal can 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 an creation block of the blockchain in the independent storage space to generate the blockchain. As shown in fig. 4, the 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, which may be specifically used to store transaction data, access data, and the like of the music class.
Further, the first terminal may also configure attributes for the blockchain, including type, key, and duration.
