Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
With the coming of the scientific and technological era and the development of the mobile internet, the pace of network revolution is getting faster and faster, the information fusion of the same field or multiple fields is realized, and the process of providing an all-dimensional informatization scheme for customers also faces new challenges of improving the system structure, supporting gravity center transfer and the like. Therefore, the blockchain technology, as a specific implementation of the distributed ledger, is gradually becoming the preferred way to store data and transaction data in various fields by virtue of its natural advantages of storing and managing data.
The block chain network shown in fig. 1 is described as an example. As shown in fig. 1, the node devices in the block chain network may include banks, insurance companies, government buildings, shops, schools, hospitals, and the like. Banks, insurance companies, government buildings, shops, schools and hospitals all participate in the management and processing of the same blockchain network, and can also participate in monitoring the legality of transactions so as to achieve the fairness of processing or storing transaction data by the blockchain network. Meanwhile, the bank, the insurance company, the government building, the shop, the school and the hospital belong to different fields, and the quality and the efficiency of social work can be better improved through information fusion and interaction in the different fields. Any node device in the blockchain network may check the acquired transaction data, and when the obtained check result is that the check is successful, a block (such as the block shown in fig. 1) may be generated based on the transaction data and issued to the blockchain, so that each other node device in the blockchain network may perform distributed storage on the block. For example, as shown in fig. 1, the node devices in the block chain network may include banks, insurance companies, government buildings, shops, schools, and hospitals, and the banks, insurance companies, government buildings, shops, schools, and hospitals may store the identity information of the same user a in a distributed manner, so that the user a may query the identity information of any organization.
The embodiment of the invention provides a distributed system, which can be formed by connecting a client and a plurality of node devices (any type of computing devices in an access network, such as a server and a user terminal) in a network communication mode. Taking a distributed system as an example of a blockchain system, referring to fig. 2, fig. 2 is an optional architecture schematic diagram of the distributed system applied to the blockchain system (or blockchain network) provided by the embodiment of the present invention, and the architecture schematic diagram is formed by a client and a plurality of node devices. A point-To-point (P2P, Peer To Peer) network is formed among the node devices, and the P2P Protocol is an application layer Protocol operating on a Transmission Control Protocol (TCP). In a distributed system, any machine, such as a server or a terminal, can join to become a node, and the node comprises a hardware layer, a middle layer, an operating system layer and an application layer. The client may also be a node device in the blockchain network.
Referring to the functions of each node in the blockchain system shown in fig. 2, the functions involved include:
1) routing, a basic function that a node has, is used to support communication between nodes.
Besides the routing function, the node may also have the following functions:
2) and the Block chain comprises a series of blocks (blocks) which are mutually connected according to the generated chronological order, new blocks cannot be removed once being added into the Block chain, and recorded data submitted by nodes in the Block chain system are recorded in the blocks.
Referring to fig. 3, fig. 3 is an optional schematic diagram of a Block Structure (Block Structure) according to an embodiment of the present invention, where each Block includes a hash value of a data record stored in the Block (hash value of the Block) and a hash value of a previous Block, and the blocks are connected by the hash values to form a Block chain. The block may include information such as a time stamp at the time of block generation. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using cryptography, and each data block contains related information for verifying the validity (anti-counterfeiting) of the information and generating a next block.
3) The application is used for being deployed in a block chain, realizing specific services according to actual service requirements, recording data related to the realization functions to form recording data, carrying a digital signature in the recording data to represent a source of task data, and sending the recording data to other nodes in the block chain system, so that the other nodes add the recording data to a temporary block when the source and integrity of the recording data are verified successfully.
For example, the services implemented by the application include:
3.1) a wallet for providing functions of transaction of electronic money, which includes initiating transaction (i.e. sending the transaction record of the current transaction to other nodes in the blockchain system, and storing the record data of the transaction in a temporary block of the blockchain as a response for confirming that the transaction is valid after the other nodes are successfully verified; of course, the wallet also supports the querying of the remaining electronic money in the electronic money address;
and 3.2) sharing the account book, wherein the shared account book is used for providing functions of operations such as storage, inquiry and modification of account data, the recorded data of the operations on the account data are sent to other nodes in the block chain system, and after the other nodes verify the validity, the recorded data are stored in the temporary block as a response for acknowledging that the account data are valid, and confirmation can be sent to the node initiating the operations.
3.3) Intelligent contracts, computerized agreements, which can execute the terms of a certain contract, are realized by codes deployed on a shared book for execution when certain conditions are met, and are used for completing automated transactions according to actual business requirement codes, such as inquiring the logistics state of goods purchased by a buyer and transferring the electronic money of the buyer to the address of a merchant after the buyer signs the goods; of course, smart contracts are not limited to executing contracts for trading, but may also execute contracts that process received information.
In addition, rights management is the core content of blockchain technology. At present, whether a client has an operation authority for a blockchain account is mainly detected by calling an authority management module at the bottom layer of a blockchain, but in the process of calling the authority control module to detect the authority of the client, the authority control module needs to be compiled, and the compiling process consumes longer time, so that the authority detection efficiency is low. Based on this, an embodiment of the present invention provides an operation method for a blockchain account, including the following steps: receiving an operation request which is sent by a client and aims at a target account in a block chain network, wherein the operation request carries a target operation requested by the operation request, and the target operation comprises reading resource data in the target account, transferring the resource data into the target account, transferring the resource data out of the target block chain account and the like; and calling a first intelligent contract related to the target account in the block chain network to detect whether the client side has the operation right on the target account, and executing the target operation on the target account when the client side has the operation right on the target account. In the method, the contract related to the authority management is written into the intelligent contract in advance, and the intelligent contract is directly called in the subsequent authority detection process to carry out the authority detection, so that the diversity of the authority detection mode is increased; in addition, the compiling time can be saved, and the authority detection efficiency can be improved, which is explained in detail below.
Referring to fig. 4, fig. 4 is a flowchart illustrating an operation method of a blockchain account according to an embodiment of the present invention. The operation method of the blockchain account described in the embodiment of the present invention may be applied to a node device, where the node device may be any node device of a blockchain network in the distributed system shown in fig. 2. In other embodiments, the node device is an optimal node device determined according to a load condition, a response time, and a distance from a client of each node device in the block chain network. The operation method of the blockchain account described in the embodiment of the invention comprises the following steps:
s401, receiving an operation request which is sent by a client and aims at a target account in a block chain network, wherein the operation request carries a requested target operation.
In the embodiment of the invention, the target account is a block chain account in a block chain network; the target operation requested by the operation request may be an operation of reading resource data in a target account, transferring resource data into the target account, or transferring resource data out of the target blockchain account. The node device may obtain the requested target operation carried by the operation request immediately after receiving the operation request for the target account sent by the client; or, when it is detected that the client has the operation right for the target account in the following, the requested target operation carried by the client is obtained from the operation request.
S402, calling a first intelligent contract related to the target account in the block chain network to detect whether the client side has the operation authority of the target account, and obtaining a detection result.
In the embodiment of the invention, the first intelligent contract is a permission management contract which is issued in advance in the block chain network, is related to the target account and can be used for permission detection. In one embodiment, the node device calls a first intelligent contract related to a target account in the blockchain network to obtain an authorization list of the target account, wherein the authorization list comprises a plurality of authorization identifications having operation permission for the target account. The authorization identifier is an identifier of a terminal with an operation authority to the target account; the identifier can be a character string which can uniquely identify the terminal, such as an IP address or an MAC address of the terminal, and the identifier can also be obtained after the character string is subjected to encryption, Hash algorithm, signature and other processing; the terminal may be a node device in a blockchain network.
Further, the node device invokes the first intelligent contract to detect whether the identity of the client initiating the operation request is an authorized identity in the authorization list. The identification of the client can be a character string which can uniquely identify the client, such as an IP address or an MAC address of the client, and the identification can also be obtained after the character string is subjected to encryption, Hash algorithm, signature and the like; the identification of the client is consistent with the calculation mode of the authorization identification. If the identifier of the client is detected to be the authorization identifier in the authorization list, a detection result indicating that the client has the operation authority for the target account is obtained, and step S403 is executed. And if the identification of the client is not the authorization identification in the authorization list, obtaining a detection result indicating that the client does not have the operation authority of the target account.
In an embodiment, if the detection result indicates that the client does not have the operation permission for the target account, the node device issues the operation request to the blockchain, and broadcasts a message that the operation request does not have the permission to a node in the blockchain network, and/or adds an identifier without permission to the operation request in the blockchain network. By the method, whether the target operation requested by the operation request is executed or not can be verified conveniently and quickly. In other embodiments, when the detection result indicates that the client does not have the operation right for the target account, the node device may reject the operation request of the client for the target account, and send a prompt message of operation failure to the client.
In another embodiment, after receiving an operation request for a target account sent by a client, a node device issues the operation request to a blockchain, and invokes the first intelligent contract to detect whether the client has an operation right for the target account after the issuance is completed, so as to obtain a detection result. Through the mode, the on-chain authority detection can be realized, the on-chain authority detection public trust is higher than the off-chain authority detection, and the safety of the block chain account can be improved.
In an embodiment, the node device invokes the first intelligent contract to detect whether the client has the operation right on the target account, and after obtaining a detection result, adds an executed identifier to the first intelligent contract related to the target account in the blockchain network. Or when the detection result indicates that the client has the operation right on the target account, adding an executed identifier for a first intelligent contract related to the target account in the block chain network. After the first intelligent contract is added with the identification of the completion of execution, the first intelligent contract will not be executed any more later. By the method, the authority management contract has timeliness, and the condition that the authority management contract is tampered can be avoided to a certain extent, so that the safety of the block chain account can be further improved.
S403, if the detection result indicates that the client has the operation authority on the target account, executing the target operation on the target account.
For example, the target operation is to read the fund balance in the target account, the node device reads the fund balance in the target account, and sends the obtained fund balance to the client. For another example, the target operation is to transfer funds of a first value into the target account, the node device adds the first value to the fund balance in the target account, and sends the updated fund balance to the client. For another example, the target operation is to transfer a second amount of funds from the target account, and the node device subtracts the second amount from the balance of funds in the target account and sends the updated balance of funds to the client. The node device may read the fund balance in the target account before transferring the fund from the target account, and detect whether the fund balance is greater than or equal to the second value; when the fund balance is greater than or equal to the second value, the node device subtracts the second value from the fund balance in the target account. And when the fund balance is smaller than the second value, the node equipment refuses the operation request of transferring the fund from the target account and sends prompt information of operation failure to the client. In other embodiments, after the node device rejects the operation request for transferring funds from the target account, the node device issues the operation request for transferring funds from the target account to the blockchain, and broadcasts a message to nodes in the blockchain network that the operation request is not responded to, and/or adds an identification of non-response to the operation request in the blockchain network. By the mode, whether the fund transfer-out operation requested by the operation request is executed or not can be verified conveniently and quickly.
The embodiment of the invention writes the contract related to the authority management into the intelligent contract in advance, and directly calls the intelligent contract to carry out the authority detection in the subsequent authority detection process, thereby increasing the diversity of the authority detection mode; in addition, the intelligent contract runs on the virtual machine, so that the compiling time can be saved to a certain extent, and the authority detection efficiency is improved.
In other embodiments, a node device receives an operation request for a target account in a blockchain network, where the operation request carries a requested target operation, and the operation request is sent by a client; calling a first intelligent contract related to a target account in a block chain network to detect whether a client side has an operation authority on the target account, and obtaining a detection result; if the detection result indicates that the client side has the operation authority on the target account, calling the first intelligent contract to detect whether the client side has the authority on executing the target operation on the target account; if yes, the target operation is executed on the target account. Otherwise, the target operation is refused to be executed on the target account.
In one embodiment, when a client does not have an operation authority for a target account or does not have an authority for executing the target operation on the target account, a node device receives an authority endowing request sent by the client, wherein the authority endowing request is used for requesting to endow the client with the authority for executing the target operation on the target account; the node equipment calls the first intelligent contract to endow the client with the authority to execute the target operation on the target account; specifically, the identification of the client may be added to the authorization list of the target account. In other embodiments, before the node device invokes the first smart contract to give the client the right to perform the target operation on the target account, it is detected whether the identifier of the client is in a target list, where the target list includes identifiers of terminals that cannot give the operation right to the target account. If the identification of the client is not in the target list, judging whether the authority for executing the target operation on the target account is the authority in the preset authority group or not according to the preset authority group; the authority in the preset authority group is an operation authority which can be automatically given to the target account. If the authority for executing the target operation on the target account is the authority in the preset authority group, the first intelligent energy contract is called to endow the client with the authority for executing the target operation on the target account. Through the mode, the authority management contract written into the intelligent contract can also realize the authority endowing function.
In another embodiment, when a client has a right to perform a target operation on a target account, a node device receives a right revoking request sent by the client, where the right revoking request is used to request to revoke a right of the client to perform the target operation on the target account or revoke an operation right of the client to the target account; and the node equipment responds to the permission revocation request, and calls the first intelligent contract to revoke the permission of the client to execute the target operation on the target blockchain account or revoke the operation permission of the client to the target account. The revoking of the operation authority of the client on the target account may specifically be to delete the identifier of the client from an authorization list of the target account. In other embodiments, if the node device detects that the client has a security risk, the node device automatically invokes the first intelligent contract to revoke the operation permission of the client on the target block chain account. The node device may detect whether the client has a security risk according to data related to the client in the blockchain network; or when receiving a message that the client has a security risk and is broadcasted by other node devices, determining that the client has the security risk. By the mode, the authority management contract written into the intelligent contract can also realize the function of authority revocation.
In other embodiments, the method for operating a blockchain account in the embodiments of the present invention may further include the following steps as shown in fig. 5:
s501, when the authorization list of the target account is changed, issuing a second intelligent contract related to the changed target account in the block chain network.
In the embodiment of the invention, the change of the authorization list of the target account comprises adding an authorization identifier in the authorization list or reducing the authorization identifier in the authorization list; the changed authorization list comprises one or more authorization identifications having operation authority for the target account; the second intelligent contract is associated with the changed target account and may be used for a rights management contract for rights detection, rights assignment, and rights revocation.
In one embodiment, before or after the node device issues a second intelligent contract related to the changed target account in the blockchain network, whether the first intelligent contract adds an identification of the executed completion is detected; and if the executed identification is not added to the first intelligent contract, adding an invalid identification to the first intelligent contract. After the first smart contract is added with the invalid identifier, it will not be executed any more later. By adopting the mode, the selection conflict between the intelligent contracts can be avoided.
S502, when an operation request which is sent by the client and aims at the changed target account is received, the second intelligent contract is called to detect whether the client has the operation authority of the changed target account, and a detection result is obtained.
In the embodiment of the invention, the node equipment calls the second intelligent contract to acquire the changed authorization list of the target account, and calls the second intelligent contract to detect whether the identifier of the client initiating the operation request is the authorization identifier in the changed authorization list. And if the identification of the client is detected to be the authorization identification in the changed authorization list, obtaining a detection result indicating that the client has the operation authority for the changed target account, and executing the operation requested by the operation request on the changed target account. If the fact that the identification of the client is not the authorization identification in the changed authorization list is detected, a detection result indicating that the client does not have the operation authority of the changed target account is obtained, the operation request of the client to the changed target account is refused, and prompt information of operation failure is sent to the client.
By adopting the mode, when the authorization list of the target account is changed, a new authority management contract can be reissued, and the new authority management contract is utilized to respond to a new operation request, so that the authority management contract related to the target account in the block chain network can be updated when the updating condition is met, the authority management contract has timeliness and is more in line with the actual requirement, the condition that the authority management contract is tampered can be avoided to a certain extent, and the safety of the block chain account is further improved.
According to the embodiment of the invention, when the operation request which is sent by the client and aims at the target account in the block chain network is received, the intelligent contract in the block chain network is called to detect whether the client has the operation authority of the target account, and when the client has the operation authority of the target account, the target operation requested by the operation request is executed on the target account, so that the authority detection is realized by using the intelligent contract, the authority detection efficiency can be improved, and the diversity of the authority detection mode can be increased.
