Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of an operation processing method in a blockchain network according to an embodiment of the present disclosure, which may be applied to role division of different blockchain accounts into administrators with different operation permissions, so as to implement a situation that a blockchain network is deployed quickly by role division. The method for processing operations in a blockchain network disclosed in the embodiments of the present application may be executed by an operation processing device in a blockchain network, where the device may be implemented by software and/or hardware, and may be integrated on a blockchain node, and the node may be deployed on any electronic device with computing capability.
As shown in fig. 1, the method for processing operations in a block chain network disclosed in the embodiment of the present application may include:
s101, determining a target administrator level corresponding to a current account according to block chain account login information of a user; wherein, different administrator levels correspond to different operation authorities in the block chain network deployment process.
In the embodiment of the present application, the blockchain accounts are divided into different administrator levels, that is, into different roles, which may include a blockchain system administrator, a network administrator, and a full-node administrator. The blockchain accounts have a corresponding relationship with the blockchain link points, for example, from the viewpoint of node types, the blockchain accounts may include a full node account and a lightweight node account. The blockchain account corresponding to the blockchain system administrator has the highest operation authority, a specific blockchain account can be designated as a network administrator, the network administrator has the authority to control the designated blockchain network, meanwhile, the network administrator has the authority to designate the specific blockchain account as a full-node administrator, and the full-node administrator has the authority to control the access of the lightweight node to the full nodes of the local computer.
The administrator level information corresponding to each blockchain account can be stored in the blockchain data in the role division process, so that the traceability and tamper-proof effects of the administrator level information corresponding to the blockchain accounts are guaranteed. A user can input mnemonics to log in an account through a management client installed on a local node; after the account is successfully logged in, the local node determines a target administrator level corresponding to the current account by utilizing a corresponding relationship between the locally pre-stored account and the administrator level to perform local query or by accessing a blockchain network according to current blockchain account login information, such as an account address or an account unique identifier.
Optionally, determining the target administrator level corresponding to the current account according to the login information of the blockchain account of the user includes: initiating a query transaction request to a blockchain network to which a local node belongs according to the blockchain account login information of a user; and determining the target administrator level corresponding to the current account according to the query result of the query transaction request. The local node can carry the login information of the blockchain account in the inquiry transaction request and send the login information to the blockchain network to which the local node belongs, and after the node in the blockchain network to which the local node belongs executes the inquiry transaction request, the inquiry result is fed back to the local node, so that the local node can determine the target administrator level corresponding to the current account according to the received inquiry result.
S102, obtaining an operation transaction request submitted by a user.
After a user completes account login on a local node, deployment operation can be executed according to the current deployment requirement of a block chain network, for example, a new parallel block chain is created in the block chain network, a new intelligent contract is deployed, block chain nodes are added or deleted, and the like, so that an operation transaction request corresponding to the deployment operation is triggered, the local node detects and acquires the operation transaction request submitted by the user, and if the execution condition of the transaction request is met, the operation transaction request is executed. The execution condition may be determined according to a specific application, for example, the operation transaction request is compliant, the operation transaction request carries a digital signature, the digital signature passes verification, the operation in the operation transaction request is within an operation authority range corresponding to the target administrator level, and the like.
For example, if the target administrator level corresponding to the current account is the blockchain system administrator, the operation transaction request submitted by the user includes at least one of the following:
a transaction request to reset current account information and a transaction request to specify a network administrator. Resetting current account information includes, but is not limited to, resetting mnemonics for blockchain accounts, and by resetting the mnemonics, account security can be enhanced. Furthermore, the user can reasonably select an account address in the blockchain network, and initiate a transaction request for designating a network administrator to the blockchain network to which the local node belongs, so as to request uplink storage of the role corresponding relation between the blockchain account address selected by the user and the network administrator, and realize that the blockchain account selected by the user is marked as the network administrator.
Second, if the target administrator level corresponding to the current account is a network administrator, the operation transaction request submitted by the user includes at least one of the following:
1) a transaction request to reset current account information; for example, a mnemonic for a blockchain account may be reset;
2) a transaction request to create a parallel blockchain (or sidechain) in the blockchain network to which the native node belongs; the block chain network to which the local node belongs is a network controlled by a home network administrator at the moment;
3) deploying a transaction request of a target intelligent contract for the parallel block chain; wherein, the content of the target intelligent contract can be set according to the service requirement;
4) adjusting the transaction request of the block chain link point in the block chain network to which the local node belongs; specifically, for example, deleting or adding the block chain link points in the block chain network to which the local node belongs to realize adjustment of the network topology structure of the block chain network to which the local node belongs;
5) appointing the affair request of a full-node administrator in the block chain network to which the local node belongs, namely the network administrator has the right to appoint a full-node administrator for each full node; for example, a user may reasonably select an account address of a full node in a blockchain network to which the local node belongs, and initiate a transaction request for designating a full-node administrator based on the selected account address, so as to request uplink storage of a role correspondence relationship between the account address selected by the user and the full-node administrator, thereby enabling a blockchain account selected by the user to be marked as the full-node administrator.
Exemplary three, if the target administrator level corresponding to the current account is a full node administrator, the operation transaction request submitted by the user includes at least one of:
1) a transaction request to reset current account information; for example, a mnemonic for a blockchain account may be reset;
2) adding or deleting a transaction request of a target lightweight node; wherein, the target lightweight node has the right to access the whole node;
3) and configuring a transaction request of the lightweight node aiming at the access authority policy of the whole node.
The full node administrator may manage lightweight nodes that have access to the native full node. Access rights policies may include, but are not limited to: the lightweight node holds a digital certificate (CA certificate) issued by a preset certification service authority, the account address of the lightweight node is in a preset account address set, and the account address of the lightweight node passes verification of a detection plug-in (which refers to a custom access control program), and the like. The preset account address set refers to an account address set of a lightweight node which has access authority to all nodes of the computer and is preset after a user finishes login of a current account, wherein the target administrator level corresponding to the current account is an all-node administrator. In addition, the access authority policy can also be set as access authority disclosure, namely any lightweight node has the authority of accessing the whole local node.
In the embodiment of the application, different operation authorities are respectively allocated to different administrator levels, executable operation refinement of each administrator role in the block chain network deployment process is realized, hierarchical management and hierarchical deployment of the block chain network are realized, potential safety hazards in the block chain network centralized deployment process of the same administrator are reduced, and flexibility in block chain network deployment realization is enhanced.
S103, if the operation in the operation transaction request is verified to correspond to the target administrator level, executing the operation transaction request.
After obtaining an operation transaction request submitted by a user, a local node needs to verify whether the operation in the operation transaction request corresponds to a currently determined target administrator level, namely, whether the operation in the operation transaction request is in an operation authority range corresponding to the target administrator level is confirmed, if so, the operation transaction request can be executed, operation transaction data are generated, and the operation transaction data are stored in a block; if not, the operation transaction execution request can be refused, so that the role-divided execution of the deployment operation is realized according to the administrator level corresponding to the blockchain account in the deployment process of the blockchain network, but not all the deployment operations are executed in a centralized manner by only one administrator role, and the flexibility of the deployment realization of the blockchain network is enhanced.
Wherein, verifying whether the operation in the operation transaction request corresponds to the target administrator level may include: matching the operation in the operation transaction request in the operation authority information corresponding to the target administrator level stored locally in the local node, wherein if the matching is successful, the verification is successful, and if the matching is failed, the verification is failed; or sending an operation verification transaction request to the blockchain network to which the local node belongs based on the operation in the operation transaction request, so as to request the node in the blockchain network to which the local node belongs to execute the operation verification transaction request, and verifying whether the operation in the operation transaction request corresponds to the target administrator level, wherein the block data stores the operation authority information corresponding to the target administrator level.
According to the technical scheme of the embodiment of the application, the role division is carried out on the block chain network accounts, and the permission operation corresponding to the target administrator level is executed according to the target administrator level corresponding to the current account in the block chain network deployment process, so that the problem that potential safety hazards and limitation exist in the execution of the deployment operation due to the fact that only one administrator account role exists when the block chain network is deployed in the existing scheme is solved, the effect of rapidly deploying the block chain network in the role division is achieved, and the flexibility of realizing the block chain network deployment is enhanced.
Fig. 2 is a flowchart of another method for processing operations in a blockchain network according to an embodiment of the present disclosure, which is further optimized and expanded based on the foregoing technical solution, and can be combined with the foregoing optional embodiments. As shown in fig. 2, the method may include:
s201, determining a target administrator level corresponding to a current account according to the block chain account login information of a user; wherein, different administrator levels correspond to different operation authorities in the block chain network deployment process.
S202, acquiring an operation transaction request submitted by a user; and the operation transaction request comprises the digital signature of the current account.
Specifically, after the user completes the login operation of the current account, according to the current deployment requirement of the block chain network, in the process of triggering the operation transaction request, the local node may automatically invoke the private key of the current account to sign the operation transaction request, and the signature may be used to verify the identity of the administrator corresponding to the current account.
And S203, calling a pre-deployed identity authentication intelligent contract, and verifying the digital signature in the operation transaction request.
The identity authentication intelligent contract is pre-deployed in a blockchain network, for example, a foundational block, and has the function of verifying a digital signature, so that account identity authentication is realized. Aiming at a block chain system administrator, a network administrator and a full node administrator, an identity authentication intelligent contract can be utilized to automatically verify a digital signature in an operation transaction request submitted by a user after the user finishes account login, so that the traceability of identity authentication operation is ensured, and the transparency and the reliability of the identity authentication operation are improved.
Generally, it is considered that the administrator identity of each full node is secret and does not need to be exposed, and at this time, the digital signature of the administrator identity does not need to be verified by using an identity authentication intelligent contract, so that if the target administrator level corresponding to the current account is a full-node administrator, after acquiring an operation transaction request submitted by a user, the method disclosed in the embodiment of the present application may further include: the digital signature in the operation transaction request is locally verified. That is, in the embodiment of the present application, it may be preferable to write the identity certificates of the blockchain system administrator and the network administrator into the blockchain network system-level intelligent contract, and perform the identity certificate of the full-node administrator locally on the node device, for example, verify the digital signature in the acquired operation transaction request by using the pre-acquired full-node account public key. After the full-node account is designated as the full-node administrator, the full node stores the account address belonging to the administrator level locally, for example, the full node receives a transaction request designating the full-node administrator, verifies a digital signature in the transaction request, and stores the account address belonging to the full-node administrator level locally if the verification is passed. The administrator identity authentication of each full node is locally executed, so that the influence on the normal operation of the blockchain network can be avoided, and the data processing pressure of the blockchain network can be relieved.
S204, verifying whether the operation in the operation transaction request corresponds to the target administrator level.
If so, continue to perform operation S205; if not, operation S206 is performed.
It should be noted that there is no strict execution order between operations S203 and S204, and the operations may be executed in parallel or in series.
S205, if the digital signature verification is passed and the operation in the operation transaction request corresponds to the target administrator level, executing the operation transaction request.
S206, refusing to execute the operation transaction request. And, if the digital signature verification fails, the execution of the operation transaction request is likewise denied.
According to the technical scheme of the embodiment of the application, the role division is firstly carried out on the block chain network account, then in the block chain network deployment process, the identity authentication intelligent contract which is deployed in advance is called to carry out identity authentication on the current account, the traceability of the identity authentication operation is ensured, the transparency and the reliability of the identity authentication operation are improved, finally, if the authentication is passed, and the operation in the operation transaction request corresponds to the target administrator level of the current account, the operation transaction request is executed, the problem that the execution of the deployment operation has potential safety hazards and limitation due to the fact that only one administrator account role exists when the block chain network is deployed in the existing scheme is solved, the effect of rapidly deploying the block chain network in a sub-role mode is achieved, and the flexibility of achieving the block chain network deployment is enhanced.
On the basis of the foregoing technical solution, further, if the target administrator level corresponding to the current account is a blockchain system administrator, before obtaining the operation transaction request submitted by the user, the method disclosed in the embodiment of the present application may further include:
acquiring a block chain network deployment request submitted by a user;
respectively sending a node general program packet and a network configuration data packet to target node equipment according to the block chain network deployment request; the node general program packet and the network configuration data packet define data required by the target node device to join the blockchain network.
Specifically, a user may trigger a blockchain network deployment request according to an initial deployment requirement of a blockchain network, and then determine a node common program package and a network configuration data package according to a device configuration performance requirement and network topology configuration information, where the device configuration performance requirement may include, but is not limited to, a system throughput requirement (TPS requirement, which refers to the number of transaction requests or transactions processed per second), an average size of the transaction requests or transactions, a consensus mechanism, and the like, and the network topology configuration information may include, but is not limited to, the number of nodes, a device IP, a port number, and the like. After acquiring a block chain network deployment request submitted by a user, a local node respectively sends a node general program package and a network configuration data package to target node equipment (namely node equipment to be deployed); and after receiving the general program package and the network deployment package, the target node equipment locally executes node deployment operation so as to join the blockchain network.
For example, the content in the node generic package may include, but is not limited to, a node program, an identity authentication program (e.g., CA program), a database program, a search service program, and the like, and the content in the network configuration package may include, but is not limited to, identity authentication authorization configuration information, creation block configuration information, consensus mechanism configuration information, and the like. The specific contents of the node general program packet and the network configuration data packet may be set according to actual situations, and the embodiment of the present application is not particularly limited. It should be noted that, since the IP and port numbers of different node devices are different, the network configuration packets received by different destination node devices are different, and the local node also needs to use the network configuration packet corresponding to its own information, but different destination node devices including the local node may use the same node general-purpose package.
In addition, after acquiring the blockchain network deployment request submitted by the user, the local node can verify the digital signature carried in the deployment request to confirm that the blockchain system administrator corresponding to the current account is verified, if the verification is successful, the sending operation of the general program packet and the network configuration data packet is executed, and if the verification is unsuccessful, the sending operation of the general program packet and the network configuration data packet can be refused to be executed.
By executing specific authority operation in the block chain network deployment process by a block chain system administrator, the phenomenon that the block chain system administrator executes all deployment related operations in a centralized manner is avoided, the executable operation refinement of each administrator role is realized, and the hierarchical management and the hierarchical deployment of the block chain network are realized.
Fig. 3 is a schematic diagram of administrator creation at different levels in a blockchain network according to an embodiment of the present application, for further explaining the embodiment of the present application. As shown in fig. 3, a system level intelligent contract in a blockchain network predefines a default blockchain system administrator account in a created block and default mnemonics to be used when recovering the account; when a blockchain network is initialized, a user A uses a default mnemonic word to log in an account to obtain temporary authority of a system administrator, and then a new mnemonic word is obtained by resetting account information, the blockchain account address, a public key and a private key can be automatically recovered for the user A in the process, the private key can be used for signing a related operation request, and the account address can be used for declaring the account identity; the user A uses the new mnemonic words to log in the account again to obtain the authority of the formal system administrator; the user a may initiate an operation of creating a blockchain network, and may further initiate an operation of creating a network administrator, and the network administrator has a control authority for a specific blockchain.
Assume that the network administrator binds to the blockchain account address of user B. In the starting stage, a user B can register to the blockchain network platform and acquire mnemonics and account addresses; when the blockchain system administrator designates the blockchain account of the user B as the network administrator, the user B acquires the authority of the network administrator after logging in the account, and then can initiate the operation of creating the full-node administrator.
Assume that the full node administrator binds to the blockchain account address of user C. In the beginning stage, the user C can also register to the blockchain network platform and obtain mnemonics and account addresses; when the network administrator designates the blockchain account of the user C as a full-node administrator, the user C acquires the authority of the full-node administrator after logging in the account, and can control the lightweight nodes with the authority to access the full nodes of the local computer.
Assuming that the user D belongs to a lightweight node user, the user D can also register to the blockchain network platform and acquire mnemonics and account addresses; when the block chain account address of the user D is bound by the full node administrator, that is, the lightweight node corresponding to the user D has the access right to access the full node corresponding to the user C.
Fig. 4 is a schematic diagram of a block chain network deployment architecture disclosed in an embodiment of the present application, for further explaining the embodiment of the present application. As shown in fig. 4, after any blockchain account obtains the authority of the network administrator, the network topology and performance requirements of the particular blockchain network may be set, where the particular blockchain network includes a plurality of full nodes, such as the full node 1, the full node 2, the full node 3, and the like shown in fig. 4, each full node uses the same full node general program packet, but different full nodes use full node network configuration data packets corresponding to the respective full node, because the IP and port numbers of different full node devices are different. The network administrator can designate a full node administrator of each full node, and the full node administrator can set the lightweight node authorization configuration information so that the lightweight node with the access authority can access the local full node.
