Detailed Description
The following description of the embodiments of the present invention 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 invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Aiming at the problems of complex operation, low efficiency and the like commonly existing in the prior art of changing account management functions, the embodiment of the invention provides an account management method which can conveniently and efficiently manage accounts by utilizing intelligent contracts and flexibly change the logic of account management.
Referring to fig. 1a, an architecture diagram of an account management system according to an embodiment of the present invention includes a blockchain network 10 and a user terminal 102, wherein:
the blockchain network 10 refers to a network for data sharing from node to node, and a plurality of nodes 101 may be included in the blockchain network. Each node 101 may receive input information while operating normally and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information. In order To ensure information intercommunication in the blockchain network, information connection can exist between every two nodes, point-To-point (P2P) communication can be realized between any two nodes, and particularly P2P communication can be performed 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, an on-board smart terminal, etc., which is not limited in the embodiment of the present invention.
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 node identifier corresponding to the node identifier, and each node in the blockchain network can store the node identifiers of other nodes in the blockchain network, so that the generated blocks can be broadcast to other nodes in the blockchain network according to the node identifiers of the 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 internet protocol (Internet Protocol, IP) address, or any other information that can be used to identify the node, and the table is described only by way of example as an IP address.
Wherein each node in the blockchain network stores one and the same blockchain. The blockchain is composed of a plurality of blocks, see fig. 1b, the blockchain 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 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, referring to fig. 1c, when the node where the blockchain is located receives input information, checking the input information, after the checking is completed, 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:
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; 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 network where the newly generated blocks are located according to the node identifications of other nodes in the blockchain network, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the blockchain stored in the newly generated blocks after the verification is completed.
The intelligent contract is a code implementation for executing when a certain condition is met, a developer can define contract logic through a programming language, issue the contract logic to a blockchain (intelligent contract registration), call a key or trigger execution according to the logic of contract clauses to complete the contract logic, and simultaneously provide functions of upgrading and logging off the intelligent contract.
In some possible embodiments, the node 101 of the 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, and 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, broadcast a respective signed consensus verification result, and the node 101 detects whether the signed consensus verification result of the other nodes meets a triggering condition by invoking an intelligent contract, if yes, the node 101 invokes the intelligent contract to manage an account included in the blockchain according to the account identifier and the operation type of the target blockchain account, thereby managing the account conveniently and efficiently by using the intelligent contract, and flexibly changing logic of account management.
In some possible embodiments, the node 101 of the blockchain network decrypts the signed consensus verification result broadcast 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 triggering condition by calling the 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.
