The user refers to a user who requests to repair the corresponding maintenance device. The maintenance equipment refers to equipment needing to be maintained, such as a smart phone, a vehicle and the like. Wherein:
the blockchain network 100 refers to a network for performing data sharing between nodes. The blockchain network may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the blockchain network. Each node 101 may receive input information and maintain shared data within the blockchain network based on the received input information while operating normally. In order to ensure information intercommunication in the blockchain network, information connection can exist between each node in the blockchain network, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network receives input information, other nodes in the blockchain network 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 blockchain network are consistent.
The terminal device 102 may access the blockchain network and may communicate with nodes in the blockchain network, e.g., send maintenance records of maintenance devices to the nodes, etc. The terminal device 103 may also access the blockchain network and may communicate with nodes in the blockchain network, for example, may receive a signature confirmation request sent by the node, and so on. It should be noted that the number of nodes shown in fig. 1A is merely illustrative, and any number of nodes may be deployed according to actual needs.
Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network 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, and table 1 only illustrates the IP address as an example.
Node name Node identification
Node 1 117.114.151.174
Node 2 117.116.189.145
… …
Node N 119.123.789.258
Each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 1B, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header 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, referring to fig. 1C, when the node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree 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 where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain network where the newly generated blocks are located according to the node identifications of the other nodes in the block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
The intelligent contract can be operated on the nodes of the block chain network, the intelligent contract is realized by codes executed when a certain condition is met, developers can define contract logic through a programming language, issue the contract logic to the block chain (intelligent contract registration), and call keys or other events to trigger execution according to the logic of contract terms to complete the contract logic and simultaneously provide the functions of upgrading and cancelling the intelligent contract.
In some possible embodiments, a node 101 in the blockchain network may obtain a service record of a service device and a first digital signature corresponding to the service record, where the first digital signature is generated according to signature information of the service record on a corresponding terminal device 102 by a service person. The signature information corresponding to the maintenance personnel can be used for identifying the identity of the maintenance personnel and representing that the maintenance personnel approve the maintenance record. For example, the signature information corresponding to the service person may include a handwritten signature (e.g., a handwritten name) of the service person. The node 101 may send a signature confirmation request to the terminal device 103 corresponding to the user, where the signature confirmation request carries the maintenance record and the first digital signature, so that the terminal device 103 generates a second digital signature according to the signature information of the user on the maintenance record and the first digital signature. The signature information corresponding to the user can be used for identifying the user identity and representing that the user approves the maintenance record. For example, the signature information corresponding to the user may include a handwritten signature (e.g., a handwritten name) of the user. Node 101 may receive the second digital signature sent by the terminal device 103, and write the repair record, the first digital signature, and the second digital signature into the account corresponding to the repair device on the blockchain. By adopting the mode, the maintenance record can be more referable and reliable based on the block chain technology.

A certain node 101 in the blockchain network may obtain the maintenance record and a first digital signature corresponding to the maintenance record, and send a signature confirmation request to the mobile phone 1 corresponding to the user a, where the signature confirmation request carries the maintenance record and the first digital signature. After receiving the maintenance record and the first digital signature, the mobile phone 1 may display the maintenance record and the first digital signature. User a may add signature information 2 to the service record and the first digital signature. After the user a adds the signature information 2, the mobile phone 1 may obtain the signature information 2, generate a second digital signature according to the signature information 2, and send the second digital signature to the node 101, where the node 101 may receive the second digital signature sent by the mobile phone 1, and write the maintenance record, the first digital signature, and the second digital signature into an account corresponding to the block chain of the mobile phone 1.
