All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the problems of complicated operation, low efficiency and the like commonly existing in the current account management function change, the embodiment of the invention provides an account management method, which can conveniently and efficiently manage accounts by utilizing intelligent contracts and can flexibly change the logic of account management.
Referring to fig. 1a, it is a schematic structural diagram of an account management system according to an embodiment of the present invention, where the account management system includes a blockchain network 10 and a user terminal 102, where:
the blockchain network 10 refers to a network for performing data sharing between nodes, and a plurality of nodes 101 may be included in the blockchain network. Each node 101 may receive input information and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information while operating normally. In order To ensure information intercommunication in the blockchain network, each node may have information connection, and any two nodes may implement Peer-To-Peer (P2P) communication, and specifically may perform P2P communication through a wired communication link or a wireless communication link. For example, when any node in the blockchain network receives input information, other nodes 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 user terminal 102 may access the blockchain network and may communicate with nodes in the blockchain network, e.g., initiate account management requests to the nodes, etc. The user terminal 102 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted smart terminal, and the like.
It should be noted that the number of nodes shown in fig. 1a is only 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 Internet Protocol (IP) address or any other information that can be used to identify the node, and the table is described by taking 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 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, referring to fig. 1c, 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 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 of a blockchain network may obtain an account management request for a target blockchain account, where the blockchain account management request includes an account identifier and an operation type of the target blockchain account, the node 101 broadcasts the account management request to other nodes in the plurality of nodes, so that the other nodes perform consensus verification on the account management request and broadcast respective signed consensus verification results, and the node 101 detects whether the other node signed consensus verification results satisfy a trigger condition by invoking an intelligent contract, and if so, the node 101 invokes the intelligent contract to manage accounts included in a blockchain according to the account identifier of the target blockchain account and the operation type, so that the accounts can be managed conveniently and efficiently by using the intelligent contract, and the logic of account management can be flexibly changed.
In some feasible embodiments, the node 101 of the block chain network decrypts the signed consensus verification result broadcasted by each node by using the public key corresponding to each node in the other nodes to obtain the consensus verification result of each node, and detects whether the consensus verification result of each node meets the trigger condition by invoking an intelligent contract, so that each consensus verification result has a private key signature, thereby effectively preventing tampering and ensuring the validity and traceability of the verification result.
In some possible embodiments, as shown in fig. 1d, in the embodiment of the present invention, management of blockchain accounts is implemented by account management contracts (i.e., intelligent contracts), which can run on virtual machines of nodes, and compared with the prior art as shown in fig. 1e, an account management module for account management is deployed in blockchain code and written in a native language of a blockchain, and when the function of the account management module is changed, configuration of all nodes needs to be restarted.

The triggering condition may be that the number of nodes passing verification reaches a preset value, for example, the number of nodes in the blockchain network is N (N may be greater than or equal to 2), and the number of nodes passing verification may be set to be greater than or equal to N/2 or N × 2/3.
204: and if so, the node calls an intelligent contract to manage the accounts included in the block chain according to the account identification and the operation type of the target block chain account.
