[0033] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0034] See also Figure 1 , is a flowchart of a blockchain service upgrade method provided in Example 1 of the present application. The blockchain to which the blockchain service upgrade method is applicable includes N nodes, where N is an integer greater than zero. For the i-th node among the N nodes, the i-th node is any node among the N nodes, such as Figure 1 As shown, the blockchain service upgrade method includes the following steps:

[0035] Step S101, obtaining a service upgrade proposal of the blockchain.

[0036] Among them, the service upgrade proposal may refer to the solution provided to achieve the service upgrade of the blockchain. The service upgrade of the blockchain is the upgrade of the corresponding node of the blockchain. The service upgrade proposal needs to be applicable to any node of the blockchain, that is, to upgrade any node. For example, when upgrading the alliance chain blockchain, the technology provider in the alliance chain is used to provide a service upgrade proposal. The technology provider needs to fully test the service upgrade proposal and compile and package it to obtain an executable file. The nodes in the alliance chain execute the executable file for upgrading. The upgraded nodes provide services to the business participants of the alliance chain. The service upgrade proposal can contain the proposal hash, the initiator's signature, the update time, the target version binary stream, the target version number and the remarks information.

[0037] Optionally, after obtaining the service upgrade proposal of the blockchain, it also includes:

[0038] Detect whether there is transaction information being processed;

[0039] Accordingly, the launch service upgrade proposal includes:

[0040] If it is detected that there is transaction information being processed, the service upgrade proposal will be initiated after the transaction information being processed is completed.

[0041] Among them, when the upgrade of the i-th node starts through the service upgrade proposal, it is also necessary to detect whether the i-th node is processing transactions, that is, whether there is transaction information being processed. Since the transaction information being processed does not belong to the pending transactions, if it is detected that there is transaction information being processed, it is necessary to wait until the transaction information being processed is completed before continuing the upgrade to avoid the loss of transaction information.

[0042] Step S102, suspending the processing of pending transaction information in the i-th node.

[0043] The pending transaction information may refer to the transaction information in the pending transaction queue of the i-th node that has not been processed, and the suspended processing may refer to the i-th node sending a suspension instruction to the process processing the pending transaction information. For example, a main process and a sub-process are set in the i-th node, and the main process sends a suspension instruction to the sub-process through an inter-process communication mechanism. After receiving the suspension instruction, the sub-process suspends processing of the pending transaction information.

[0044] Step S103, start the service upgrade proposal.

[0045] Among them, after the service upgrade plan is started, the i-th node can be upgraded. The upgrade process does not require human control and is similar to the upgrade of computer software. For example, the child process of the i-th node feeds back the corresponding information to the main process after pausing. After the main process receives the corresponding message, it reads the service upgrade proposal to start the service upgrade proposal.

[0046] Step S104: after the upgrade of the i-th node is completed, the pending transaction information is processed.

[0047] Among them, it is possible to determine whether the upgrade of the i-th node is completed by querying the version number of the software program of the i-th node. For example, when the version number of the software program of the i-th node is the target version number in the service upgrade plan, it is determined that the upgrade of the i-th node is completed; when it is detected that the version of the software program of the i-th node does not correspond to the target version number in the service upgrade plan, it is determined that the upgrade of the i-th node is not completed.

[0048] When it is detected that the upgrade of the i-th node is completed, the pending transaction information that is suspended is processed. For example, when the main process of the i-th node starts the service upgrade proposal, it also starts a new child process, passes the pending transaction information as a parameter to the new child process, and puts the new child process in a waiting state. When the upgrade of the i-th node is completed, the new child process is put in a starting state, and the new child process processes the pending transaction information after it is started.

[0049] Optionally, after the upgrade of the i-th node is completed, processing the pending transaction information includes:

[0050] After the upgrade of the i-th node is completed, the message of the completion of the upgrade of the i-th node is broadcast to other nodes, where other nodes refer to the nodes other than the i-th node among the N nodes;

[0051] Get the upgrade completion message of other nodes;

[0052] If all N nodes have been upgraded, the pending transaction information will be processed.

[0053] Among them, the message of the completion of the upgrade of the i-th node is broadcast to other nodes. At the same time, other nodes also broadcast their respective completed upgrade messages. Therefore, the i-th node can get the message of the completion of the upgrade of other nodes. If the i-th node receives the message of the completion of the upgrade broadcasted by other nodes, and the i-th node has also been upgraded, it is considered that all N nodes have been upgraded. At this time, the processing of the pending transaction information is started. For example, when the main process of the i-th node starts the service upgrade proposal, it also starts a new child process, passes the pending transaction information as a parameter to the new child process, and puts the new child process in a waiting state. When the upgrade of N nodes is completed, the new child process is put in a starting state. After the new child process is started, it processes the pending transaction information.

[0054] like Figure 2 As shown, it is a schematic diagram of the architecture of the main process in a node provided in Example 1 of the present application, wherein the transaction queue is used to store pending transaction information, and both sub-process 1 and sub-process 2 include a consensus module and a transaction processing module, which are responsible for logical processing such as consensus and transaction processing. When the node needs to be upgraded, sub-process 1 is controlled to suspend processing the pending transaction information in the transaction queue, and a new sub-process, namely sub-process 2, is generated, and the pending transaction information in the transaction queue is passed as a parameter to the sub-process 2. After the node upgrade is completed, sub-process 2 is started and begins to process the pending transaction information in the transaction queue.

[0055] In the embodiment of the present application, after any node in the blockchain obtains a service upgrade proposal, the processing of pending transaction information in the node is suspended, and the service upgrade proposal is initiated to upgrade the node. After the node upgrade is completed, the pending transaction information is processed. During the upgrade process, the node suspends the processing of pending transaction information, and processes the pending transaction information again after the upgrade is completed. There is no need to stop the operation of the node, and the node can be upgraded online without causing suspension of business other than pending transaction information in the node, which has little impact on the node's business.

[0056] See also Figure 3 , is a flowchart of a blockchain service upgrade method provided in Example 2 of the present application. The blockchain to which the blockchain service upgrade method is applicable includes N nodes, where N is an integer greater than zero. For the i-th node among the N nodes, the i-th node is any node among the N nodes, such as Figure 3 As shown, the blockchain service upgrade method includes the following steps:

[0057] Step 301, obtaining a service upgrade proposal for the blockchain.

[0058] Among them, the content of step S301 is the same as that of the above-mentioned step S101, and reference may be made to the description of step S101, which will not be repeated here.

[0059] like Figure 4 As shown, it is a schematic diagram of communication between alliance chain nodes provided in Example 2 of the present application, wherein the alliance chain includes 6 nodes, among which node 1 can be used by the technology provider, and nodes 2 to 6 can be used by business participants, and node 1 broadcasts the service upgrade proposal to nodes 2 to 6; in addition, node 1 can also be used by business participants, that is, the technology provider and the business participants reuse one node. In this case, the business participants of node 1 need to open the calling authority of the technology provider.

[0060] Step S302, obtaining the first voting result.

[0061] Among them, the first voting result includes the selection result of the i-th node on whether to upgrade through the service upgrade proposal. The selection result may include that the i-th node passes the service upgrade proposal or the i-th node does not pass the service upgrade proposal. The first voting result can be obtained by the user voting through the i-th node. The first voting result can also be obtained by the i-th node analyzing the service upgrade proposal according to its own agreement, contract, mechanism, etc.

[0062] Optionally, obtaining the first voting result includes:

[0063] Get the proposal hash of the service upgrade proposal and the signature of the initiator of the service upgrade proposal;

[0064] Call the voting interface of the i-th node to vote on the service upgrade proposal and determine the voting hash and voting intention. The voting intention is the i-th node's choice of whether to upgrade through the service upgrade proposal.

[0065] The first voting result is determined based on the proposal hash, initiator signature, voting hash, and voting intention.

[0066] Among them, the service upgrade proposal may include the proposal hash, the initiator's signature, the update time, the target version binary stream, the target version number and the remarks information, etc. After the i-th node obtains the service upgrade proposal, the binary stream in the service upgrade proposal is persisted to the local temporary storage directory of the version to be updated of the i-th node, and the file name in the local temporary storage directory of the version to be updated is named as the target version number in the service upgrade proposal.

[0067] Call the voting interface of the i-th node to vote on the service upgrade proposal. The voting result information may include the proposal hash, the initiator's signature, the voting hash and the voting intention. The proposal hash and the initiator's signature are both used to indicate the object to which the voting result is directed. The voting hash is used to indicate the uniqueness of the voting result to ensure that the voting result is not tampered with. The voting intention is the i-th node's choice result on whether to upgrade through the service upgrade proposal, that is, whether the i-th node passes the service upgrade proposal or not.

[0068] Step S303: broadcast the first voting result to other nodes.

[0069] Among them, other nodes refer to the nodes except the i-th node among the N nodes, that is, the other nodes include N-1 nodes, and each node broadcasts the first voting node to other nodes, that is, each node will receive the voting results of other nodes.

[0070] With the above Figure 4 For example, if node 1 is a node reused by the technology provider and the business participant, nodes 1 to 6 all vote on the service upgrade proposal, and node 1 broadcasts its own voting results (i.e., the first voting results) to nodes 2 to 6. Node 2 also broadcasts its own voting results (i.e., the first voting results) to nodes 1 and 3 to 6, and so on.

[0071] Step S304, obtaining the second voting result.

[0072] Among them, the second voting result includes the selection results of other nodes on whether to upgrade through the service upgrade proposal. The second voting result is the voting result of other nodes, which is in the same form as the first voting result. The i-th node can obtain the voting results of other nodes and its own voting results.

[0073] Step S305: according to the first voting result and the second voting result, suspend processing of the pending transaction information in the i-th node.

[0074] Among them, according to the voting results of all nodes, that is, N nodes, it is decided whether to execute the upgrade of the service upgrade proposal, that is, whether to start the step of suspending the processing of pending transaction information in the i-th node; for example, the number of passed votes and failed votes in the voting results of N nodes are counted. If the number of passed votes is greater than the number of failed votes, the i-th node and other nodes can be upgraded.

[0075] Optionally, according to the first voting result and the second voting result, suspending the processing of pending transaction information in the i-th node includes:

[0076] Check whether the number of passed votes is equal to N, where the number of passed votes is the number of votes that passed the selection result for upgrading the service upgrade proposal in the first voting result and the second voting result;

[0077] If it is detected that the number of passed votes is equal to N, the processing of pending transaction information in the i-th node is suspended.

[0078] Among them, since the blockchain has high requirements for node consensus, each node can be upgraded when all votes are passed, that is, when the counted number of votes is equal to the number of nodes N.

[0079] Optionally, after checking whether the number of votes passed is equal to N, the following is also included:

[0080] Get the update time of service upgrade proposal;

[0081] Check whether the current time reaches the update time;

[0082] Accordingly, if it is detected that the number of passed votes is equal to N, the pending transaction information in the i-th node is suspended, including:

[0083] If it is detected that the number of passed votes is equal to N, and it is detected that the current time has reached the update time, the processing of pending transaction information in the i-th node will be suspended.

[0084] The service upgrade proposal may also include an update time, and the format of the update time may be yyyy (year) -mm (month) -dd (day) HH:MM:SS (hour), that is, the service upgrade proposal needs to be used for node upgrade only after the update time is reached, and may be used to achieve synchronization of node upgrades.

[0085] Step S306, start the service upgrade proposal.

[0086] Step S307: After the upgrade of the i-th node is completed, the pending transaction information is processed.

[0087] Among them, the contents of step S306 and step S307 are respectively the same as those of the above-mentioned step S103 and step S104, and the description of step S103 and step S104 may be referred to, and will not be repeated here.

[0088] The service upgrade proposal of this application may include proposal hash, initiator signature, update time, target version binary stream, target version number and remarks. The corresponding fields and data types when designing the proposal can refer to the following table:

[0089]

[0090] In the embodiment of the present application, after any node in the blockchain obtains a service upgrade proposal, all nodes vote on the service upgrade proposal and decide whether to upgrade based on the voting results, thereby preventing the abuse of the service upgrade proposal and enabling the node's upgrade intention to be conveyed.
