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.

Example 1:

in recent years, blockchain technology has been rapidly developed, and blockchains can be roughly classified into public chains, private chains and alliance chains according to different application scenes and user requirements. The alliance chain has higher transaction speed than the public chain, can partially decentralize, and can realize more complex authority control.

The embodiment of the invention provides a management device for managing blockchain nodes, as shown in fig. 1, the device comprises:

a receiving unit 101, configured to receive an intelligent contract installation request sent by a supervisor, where the intelligent contract installation request includes identification information of a blockchain node of an intelligent contract to be installed;

and a sending unit 102, configured to send the smart contract to the blockchain node of the identification information, so that the blockchain node of the identification information receives and configures the smart contract.

Blockchain is considered a subverted technique primarily because intelligent contracts can be implemented on blockchain nodes and enable blockchain nodes to automatically run according to logic set in the intelligent contracts. In the prior art, when intelligent contracts are configured on the blockchain nodes, the intelligent contracts are manually configured into the corresponding blockchain nodes by a user, namely, the attribute of each blockchain node is unchangeable in the subsequent operation, and if the attribute needs to be changed, the user needs to manually configure again.

One blockchain organization corresponds to one set of blockchain nodes, another blockchain organization corresponds to another set of blockchain nodes, and one blockchain organization may contain multiple enterprises. For example, "grain" is one of the blockchain organizations that includes the following enterprises: ancient boat, wudeli, goldfish, north Dawang and the like. In order for these enterprises to commonly use blockchain nodes and to ensure safe and reliable operation of blockchain nodes, the management and supervision of trusted regulators are not separated.

The management device for managing the blockchain nodes is provided with a receiving unit and a sending unit, wherein the receiving unit is mainly used for receiving various requests generated by a supervisor, managing the blockchain nodes through various requests generated by the supervisor, and the sending unit is used for sending information to the blockchain nodes or the supervisor; the supervisor is used to manage and supervise blockchain nodes.

The management device may further include a display interface in which the supervisor inputs the corresponding request. Specifically, the receiving unit receives an intelligent contract installation request sent by a supervisor, wherein the intelligent contract installation request contains identification information of a blockchain node of an intelligent contract to be installed. In particular embodiments, each blockchain node has an identification that is unique. The transmitting unit holds in advance the smart contracts transmitted by the supervisory party. In a specific implementation process, a supervisor can specify which blockchain nodes are configured with the intelligent contract, and specifically, the supervisor can send an intelligent contract installation request to a receiving unit, wherein the intelligent contract installation request comprises identification information of the blockchain nodes to be provided with the intelligent contract, and after the receiving unit receives the intelligent contract installation request, a sending unit sends the locally pre-stored intelligent contract to the blockchain nodes with the identification information; after receiving the intelligent contract sent by the sending unit, the blockchain node of the identification information installs the intelligent contract in the blockchain node so that the blockchain node can operate according to the logic set in the intelligent contract.

In the specific implementation process, when the intelligent contract is configured, the node with authority to carry out endorsement and consensus operation is selected, so that the execution safety of the intelligent contract is ensured. Alternatively, most policies or sharding policies may be selected to prevent single or multiple malicious nodes from averting. Specifically, most strategies refer to that after most nodes in each blockchain organization are subjected to endorsement consensus, the nodes can have permission to execute intelligent contracts; the slicing strategy refers to dividing each node into groups according to a certain rule, selecting one or more nodes in each group to be identified according to a certain rule, and then carrying out unified identification party executable intelligent contract on the results obtained after the identification of each group according to the rule approved by the blockchain organization.

Example 2:

in order to better monitor the blockchain nodes, on the basis of the above embodiment, in the embodiment of the present invention, the receiving unit 101 is further configured to receive ledger information sent by each blockchain node;

The apparatus further comprises:

and the verification unit 103 is configured to determine whether the account book information of each blockchain node is consistent according to the account book information sent by each blockchain node, and if there is inconsistent account book information, notify the blockchain node to be verified corresponding to the inconsistent account book information of the blockchain node to be verified of sending intelligent contract version information and/or software version information.

In order to better realize supervision on the blockchain nodes, whether each blockchain node operates normally is determined by comparing account information stored by each blockchain node. In order to determine the operation condition of each blockchain node, the management device for managing blockchain nodes according to the embodiments of the present invention may further include a verification unit.

Specifically, each block link transmits its own identification information and its own account book information to the receiving unit. The checking unit judges whether account book information of each blockchain node is consistent, if inconsistent account book information exists, the checking unit takes the blockchain node corresponding to the account book information as the blockchain node to be checked, and the checking unit informs the blockchain node to be checked of intelligent contract information and/or software version information. Specifically, if the account book information of a certain blockchain node is inconsistent with the account book information of other blockchain nodes, the situation that the configuration information of the blockchain node is inconsistent with the configuration information of other blockchain nodes may exist, wherein the configuration information may be intelligent contract version information or software version information. In the implementation process, when the checking unit determines that account book information of a certain blockchain node is inconsistent with account book information of other blockchain nodes, specifically, the account book height of the certain blockchain node is inconsistent with the account book height of other blockchain nodes, the checking unit can take the blockchain node as the blockchain node to be checked and send notification information to the blockchain node to be checked, wherein the notification information is used for notifying that the blockchain node to be checked needs to send intelligent contract version information and/or software version information stored by the blockchain node to be checked to the receiving unit.

Therefore, in the embodiment of the present invention, the receiving unit 101 is further configured to receive intelligent contract version information and/or software version information sent by a blockchain node to be verified;

the verification unit 103 is further configured to determine whether the intelligent contract version information of the blockchain node to be verified is consistent with the pre-stored intelligent contract version information if the intelligent contract version information sent by the blockchain node to be verified exists, and if not, notify the sending unit to send the pre-stored intelligent contract version information to the blockchain node to be verified, so that the blockchain node to be verified updates the self-stored intelligent contract version information according to the intelligent contract version information; if the software version information sent by the blockchain node to be verified exists, judging whether the software version information of the blockchain node to be verified is consistent with the pre-stored software version information, if not, informing a sending unit to send the pre-stored software version information to the blockchain node to be verified, so that the blockchain node to be verified updates the self-stored software version information according to the software version information.

When there is a blockchain node for which ledger information is inconsistent with ledger information of other blockchain nodes, it may be caused by the intelligent contract installed in the blockchain node not being updated or by the software used in the blockchain node not being updated. Preferably, before starting or configuring each block link point, the supervisor will send the intelligent contract and software information to the sending unit, and the sending unit receives and stores the version information of the intelligent contract and software sent by the supervisor. Therefore, when the checking unit determines that the blockchain node to be checked exists, the checking unit can send a notification to the blockchain node to be checked, and when the blockchain node receives the notification, the receiving unit sends the intelligent contract version information and/or the software version information locally stored in the blockchain node to be checked, and receives the intelligent contract version information and/or the software version information sent by the blockchain node to be checked.

When receiving the intelligent contract version information sent by the blockchain node to be checked, judging whether the intelligent contract version information of the blockchain node to be checked is consistent with the pre-stored intelligent contract version information, if not, the checking unit informs the sending unit to send the pre-stored intelligent contract version information to the blockchain node to be checked, and after the blockchain node to be checked receives the intelligent contract version information, updating the intelligent contract version information stored by the blockchain node to be checked according to the intelligent contract version information. When receiving the software version information sent by the blockchain node to be verified, judging whether the software version information of the blockchain node to be verified is consistent with the pre-stored software version information, if not, the verification unit informs the sending unit to send the pre-stored software version information to the blockchain node to be verified, and after receiving the software version information, the blockchain node to be verified updates the software version information stored by the blockchain node to be verified according to the software version information.

Example 3:

in order to better implement supervision on the blockchain nodes, in the embodiments of the present invention, the receiving unit 101 is further configured to receive node information sent by each blockchain node and/or information of a server where the node is located;

the verification unit 103 is further configured to determine, according to the node information sent by each blockchain node and/or the information of the server where the node is located, whether the node and/or the server are normal, and if not, notify the sending unit to send an abnormal alarm.

In the running process of the block chain link points, in order to better monitor the block chain nodes, in the embodiment of the invention, the management device for managing the block chain nodes can monitor the node running state of each block chain node or the information of the server where each block chain point is located.

Specifically, each blockchain node sends node information of the blockchain node and/or information of a server where the node is located to a receiving unit, the receiving unit receives the node information sent by each blockchain node and/or information of the server where the node is located, and a checking unit judges whether the node and/or the server are normal or not according to the node information of each blockchain node and/or the information of the server where the node is located.

Specifically, if the node information is abnormal, determining that the blockchain node is abnormal, and notifying a sending unit to send an abnormal alarm, wherein the node information can be the running state of the node, for example, the node is in the running state or in the pause state; if the information of the server where the node is located is abnormal, determining that the server where the node is located is abnormal, and notifying the sending unit to send an abnormal alarm, wherein the information of the server where the node is located can be the resource occupancy rate in the server, when the resource occupancy rate of the server exceeds a preset threshold, determining that the server is abnormal, for example, the resource occupancy rate of the server is 90% and exceeds the preset threshold 70%, and determining that the server is abnormal. In the specific implementation process, an abnormal alarm can be sent to the supervisor, specifically, the supervisor is informed of the abnormality by means of early warning mail or short message notification, so that the supervisor is informed of the abnormality of the block link point, and the supervisor performs subsequent operations, such as restarting operations, according to the abnormal alarm.

In the implementation process, the blockchain node may send the node information of the blockchain node or the information of the server where the node is located to the receiving unit in real time or at a fixed time.

In the embodiment of the invention, the node information comprises node state information and node log information;

The node information includes node state information and node log information, wherein the node state information refers to an operation state of a node, for example, the node is in an operation state or a suspension state; the information of the server where the node is located includes server resource occupancy information. The specific operation condition of the node is recorded in the node log information, wherein the specific operation condition comprises a normal operation condition and an abnormal operation condition, so that whether the node is abnormal or not can be determined according to the node log information.

Example 4:

in order to better implement supervision on blockchain nodes, in the embodiments of the present invention, the receiving unit 101 is further configured to receive a node management request sent by a supervision party, where the node management request carries identification information of a node;

the apparatus further comprises:

and the control unit 104 is configured to process the corresponding node according to the received node management request and the identification information of each node stored in the control unit.

In order to realize the management of the blockchain node, the supervisor can realize the functions of creating the blockchain node, deleting the blockchain node or inquiring the blockchain node, and therefore, the management device for managing the blockchain node further comprises a control unit. Specifically, when the supervisor needs to manage the blockchain node, the supervisor may send a node management request, and the receiving unit receives the node management request sent by the supervisor, where the node management request carries identification information of the node, where the identification information is unique, for example, the identification information may be address information of the node, or may be information that uniquely identifies the node such as a number of the node. Because the corresponding relation between each blockchain node and the identification information of the node is saved when the blockchain node is created. Therefore, the control unit performs corresponding processing on the blockchain node corresponding to the identification information of each node according to the received node management request and the pre-stored identification information of the node.

Thus, in an embodiment of the present invention, the node management request includes a node creation request, a node deletion request, and a node query request.

Specifically, when the node management request is a node creation request, a blockchain node is created, specifically, an IP network segment to which the blockchain node belongs and a domain name corresponding to the IP network segment may be created, the blockchain node is created in the server, and after the blockchain node is created, information of the blockchain node may be recorded in the control unit, for example, identification information of a blockchain organization to which the blockchain node belongs, identification information of the blockchain node, and the like; deleting the block chain node of the identification information when the node management request is a node deletion request; when the node management request is a node query request, the control unit queries various information of the blockchain node of the identification information, such as information of an operation state of the node.

Optionally, the node types can be divided into an accounting node, a consensus node and a supervision node, wherein the node issues a node certificate for identifying the identity to the node after verifying the identity of the node by generating an admission request to a trusted organization. Wherein, the accounting node records the complete account book data of the blockchain system; the consensus node ensures that the blockchain system achieves the whole network consensus according to a certain rule, and ensures the consistency and the effectiveness of the transaction; the supervising node can supervise all data in the nodes in the blockchain organization, and ensure the supervising requirement of the blockchain organization on the nodes in the organization.

Example 5:

in order to better implement the supervision on the blockchain node, in the embodiments of the present invention, the receiving unit 101 is further configured to receive an enterprise management request, where the enterprise management request includes identification information of the enterprise and identification information of a blockchain organization to which the enterprise belongs;

the apparatus further comprises:

and the management unit 105 is configured to verify the enterprise management request according to the enterprise management request and the stored identification information of each blockchain organization, and operate information corresponding to the blockchain organization corresponding to the enterprise after the verification is passed.

In order to achieve management of blockchain organizations, a supervisor may achieve a function of managing an enterprise joining blockchain nodes, and thus the management apparatus for managing blockchain nodes further includes a management unit. Specifically, when the supervisor needs to manage the enterprise, the supervisor may send an enterprise management request, and the receiving unit receives the enterprise management request sent by the supervisor, where the enterprise management request carries identification information of the enterprise and carries identification information of a blockchain organization to which the enterprise belongs, where the identification information of the enterprise is unique, for example, the identification information of the enterprise may be information that uniquely identifies the enterprise, such as a serial number of the enterprise; the identification information of the blockchain organization to which the enterprise belongs may be information that uniquely identifies the blockchain organization, such as a serial number of the blockchain organization.

Because the corresponding relationship between each blockchain organization and the corresponding enterprise is preserved when the corresponding enterprise in the blockchain organization is created. Therefore, the management unit verifies the enterprise management request according to the received enterprise management request and the prestored identification information of each blockchain organization, and when the verification is passed, the management unit operates the information corresponding to the blockchain organization corresponding to the enterprise. And carrying out corresponding processing on the blockchain node corresponding to the identification information of the node. The specific verification process is to verify by comparing the identification information of the blockchain organizations carried in the enterprise management request with the stored identification information of each blockchain organization.

Thus, in an embodiment of the present invention, the enterprise management request includes an add enterprise request, a delete enterprise request, and a query enterprise request.

Specifically, when the enterprise management request is an add enterprise request, the management unit adds the enterprise to the blockchain organization; when the enterprise management request is an enterprise deletion request, the management unit performs deletion operation on the enterprise corresponding to the identification information of the enterprise in the corresponding blockchain organization; when the enterprise management request is a query enterprise request, the management unit queries information of the enterprise for the identification information.

In implementations, different blockchain organizations create different nodes, and enterprises within a blockchain organization may share blockchain nodes within the organization, so that multiple blockchain points in a blockchain organization correspond to one chain, e.g., there are 5 blockchain organizations, and there are 5 chains. The different chains should be completely isolated to ensure data isolation between different applications and services, meet the requirement of privacy protection of users, and support writing the data which need to be isolated into different chains. Optionally, data privacy protection based on cryptography can be provided for sensitive data, so that the security of the data is ensured and the requirements of various privacy protection are met. Meanwhile, the management system has authority to dynamically add the block chain organization and organization members which are newly added in the established chain, so that dynamic allocation is realized.

Example 6:

in order to better implement supervision on blockchain nodes, in the above embodiments, the receiving unit 101 is further configured to receive a user registration request, where the user registration request includes identification information of a user to be registered;

the management unit 105 is further configured to determine whether there is identification information of the user to be registered according to the user registration request and the stored information of the registered user, and if not, store the identification information of the user to be registered in the information of the registered user, allocate a corresponding right for the user to be registered and allocate a certificate corresponding to the right.

There are also multiple users in each registered enterprise that can be employees in the enterprise, so that each user has different rights in the blockchain node. For example, some users may only query the data in the blockchain node, some users may write data in the blockchain node, and some users may query the data in the blockchain node, may write data, etc. Therefore, when registering a user, the rights corresponding to the user should also be allocated.

Specifically, when a new user wants to access data in a blockchain node or write data in the blockchain node, the new user first needs to register in the management device, and after the registration is completed, the user can perform corresponding operation according to the corresponding authority.

Specifically, the receiving unit receives a user registration request sent by a supervisor, where the user registration request includes identification information of a user to be registered, where the identification information of the user to be registered is unique, for example, the identification information of the user to be registered may be information that uniquely identifies the user, such as an identification card number of the user. The management unit judges whether the identification information of the user to be registered exists in the information of the user according to the identification information of the user to be registered in the user registration request and the pre-stored information of the user which is already registered, if not, the identification information of the user to be registered is stored in the information of the user which is already registered, and corresponding permission and corresponding certificates are allocated to the user to be registered, wherein the certificates can comprise a signature certificate and an encryption certificate, and the signature certificate is used for identifying the identity of the user so as to access a blockchain network; the encryption certificate is used for data privacy protection of the user. In particular implementations, the user's rights include administrator rights, guest rights, and specific rights, such as rights that can only apply for certificates. In the specific implementation process, the supervisor can input the authority corresponding to the user to be registered to the management unit; the user may apply for an attribute certificate through which the corresponding rights are assigned to the user.

In the specific implementation process, the supervisor can also send a user logout request or a user update information request to the receiving unit; when the request is a user logout request, the receiving unit also receives identification information of a user sent by a monitoring party, and the management unit completes logout operation of the user according to the user logout request and the identification information of the user; when the request is a user update information request, the receiving unit also receives the identification information of the user and the user information to be updated sent by the monitoring party, and the management unit completes the update operation of the user information of the user according to the user update information request and the user information to be updated.

For example, fig. 2 is a schematic diagram of a management device for managing blockchain nodes according to an embodiment of the present invention, where the management device is divided according to functions that can be implemented, including organization management, node management, multi-chain management, intelligent contract management, early warning management, and data analysis, and the specific processes include:

the block chain organization obtains a trusted organization certificate through a trusted third party CA application, and the verification certificate chain can be accessed to the block chain node only after being safe. Specifically, the blockchain organization may be accessed through a unique third party CA that is trusted, or through a different third party CA that is trusted by the management device. The third party CA can issue a national secret certificate so as to meet the requirements of domestic policies and simultaneously ensure the security requirements of autonomous security controllable blockchain nodes. The receiving unit processes the corresponding nodes according to the received node management request and the identification information of each node stored by the control unit, and specifically, the operations of creating the nodes, deleting the nodes or inquiring the nodes and the like can be realized, so that the management of the nodes is realized.

After the initialization of the blockchain system, each organization node is started to operate, one or more chains are created after the operation is normal, and the blockchain organization and nodes required by each chain are selected to be added into the appointed chain, so that the function of multi-chain management is realized.

The receiving unit receives an intelligent contract installation request sent by a supervision party, and the sending unit sends an intelligent contract to the blockchain node of the identification information so that the blockchain node of the identification information receives and installs the intelligent contract to realize the management of the intelligent contract. The receiving unit also receives node information sent by each block chain node and information of a server where the node is located; the verification unit judges whether the node or the server is normal according to the node information of each blockchain node or the information of the server where the node is located, and if not, the notification sending unit sends an abnormal alarm, so that the function of early warning management of the blockchain node is realized.
