The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a deployment method of a blockchain node according to an embodiment of the present application. The embodiment provides a deployment method of a blockchain node, an execution main body of which is a BaaS platform server, and the deployment method of the blockchain node specifically comprises the following steps:
s201, receiving a blockchain node adding instruction, wherein the blockchain node adding instruction comprises identity information of a blockchain node to be added.
In this embodiment, the BaaS platform server is configured with a Web front end, and when a new blockchain node needs to be added to the blockchain network deployed in the BaaS platform, a user may send a blockchain point adding instruction to the BaaS platform server through the Web front end, where the blockchain point adding instruction carries identity information of the blockchain node to be added, including, but not limited to, a name of the blockchain node to be added, and the like.
S202, carrying out identity registration on the blockchain node to be added in the blockchain network according to the identity information.
In this embodiment, the identity of the blockchain node to be added needs to be registered in the blockchain network, so that each blockchain node in the blockchain network knows the identity of the blockchain node to be added, and specifically, a transaction including the identity information of the blockchain node to be added can be issued in the blockchain network.
Alternatively, any operation of the BaaS platform server on the blockchain network in this embodiment may be performed by a blockchain proxy node of the blockchain network. Further, in S202, the BaaS platform server may send a blockchain node addition instruction to the blockchain proxy node, and control the blockchain proxy node to perform identity registration on the blockchain node to be added in the blockchain network according to the identity information.
Optionally, after the identity registration of the blockchain node to be added is completed, the blockchain proxy node may notify the BaaS platform server that the blockchain node to be added has completed the identity registration.
S203, calling a resource layer service to create and start the blockchain node to be added in the blockchain network.
In this embodiment, after the identity registration of the blockchain node to be added is completed, the BaaS platform server invokes a resource layer service to create the blockchain node to be added in the blockchain network, where the resource layer service may be Kubernetes (K8 s) is a container orchestration engine supporting automated deployment, large-scale scalability, and application containerization management, and through Kubernetes, a Pod of the blockchain node to be added is created, where the Pod is a minimum deployable computing unit that may be created and managed in Kubernetes, and is a set (one or more) of containers in which the service of the blockchain node to be added actually runs. It should be noted that Pod is started, but the service actually deployed in Pod is not necessarily started.
After the Pod of the blockchain node to be added is created by the Kubernetes, the blockchain node can be created according to a preset blockchain node template, and the blockchain node to be added is configured according to the identity information of the blockchain node to be added, so that the creation of the blockchain node to be added is completed.
Further, the blockchain node to be added is started, namely, the service of the blockchain node to be added in the Pod is started, so that the blockchain node to be added provides http access, but the blockchain node to be added is not a consensus node at the moment and cannot participate in consensus in the blockchain network.
S204, synchronizing the blockchain ledger in the blockchain network to the blockchain node to be added, and activating the blockchain node to be added.
In this embodiment, after the block link point service to be added is started, the BaaS platform server may initiate activation of the block chain node to be added, so that the block link point to be added becomes a consensus node and can participate in consensus in the block chain network.
Specifically, the BaaS platform server may control the blockchain account book in the blockchain link point synchronization blockchain network to be added, and after the blockchain account book synchronization is completed, may control the blockchain node to be added to modify the state to be a consensus node, and update the network topology of the blockchain network, so that the blockchain node really becomes the consensus node in the blockchain network, and other consensus nodes may perform heartbeat detection with the consensus node and may participate in the consensus in the blockchain network.
Optionally, when activating the blockchain node to be added, the BaaS platform server may send an activation instruction to the blockchain proxy node, so that the blockchain proxy node determines the blockchain link point to be added as a consensus node in the blockchain network, and updates the network topology of the blockchain network.
Optionally, because a plurality of different blockchain ledgers may be deployed in the blockchain network, different blockchain ledgers may have different blockchain nodes participating, synchronizing one or more target blockchain ledgers may be designated when the blockchain ledgers in the blockchain network are to be synchronized with the added blockchain points. Specifically, a user can send a blockchain ledger selection instruction to a BaaS platform server through a Web front end, wherein the blockchain ledger selection instruction comprises any target blockchain ledger in a blockchain network; after receiving the blockchain ledger selection instruction, the BaaS platform server can control the blockchain node to be added to acquire the target blockchain ledger from any blockchain node of the blockchain network through the blockchain proxy node for synchronization, so that the flexibility of deploying the blockchain ledger for the blockchain node to be added is improved.
According to the deployment method of the blockchain node, the blockchain node adding instruction is received, wherein the blockchain node adding instruction comprises identity information of the blockchain node to be added; registering identities of blockchain nodes to be added in a blockchain network according to the identity information; invoking a resource layer service to create and start a block chain node to be added in the block chain network; synchronizing a blockchain ledger in the blockchain network to the blockchain node to be added, and activating the blockchain node to be added. The embodiment can dynamically add new block chain nodes to the block chain network of the BaaS platform, and improves the flexibility and convenience of configuring the block chain network of the BaaS platform.
On the basis of any one of the above embodiments, the deployment method of the blockchain node provided in the embodiments of the present application further provides a method for logging off the blockchain node in the blockchain network, as shown in fig. 3, which specifically includes the following steps:
s301, receiving a cancellation instruction of the block chain node to be cancelled.
In this embodiment, when any blockchain link point in the blockchain network needs to be logged out, the user may send a logging-out instruction for the blockchain node to be logged out to the BaaS platform server through the Web front end.
S302, inquiring all the blockchain account books related to the blockchain link points to be logged out according to the log-out instruction.
In this embodiment, the BaaS platform server may request a database to query all blockchain ledgers related to the blockchain points to be logged out, so as to log out node information of the blockchain nodes to be logged out from all blockchain ledgers.
S303, canceling node information of the block chain node to be canceled for all the block chain account books related to the block chain link points to be canceled.
In this embodiment, for any blockchain ledger related to the blockchain link point to be logged off, node information of the blockchain node to be logged off is logged off, that is, the blockchain node to be logged off is determined to be an invalid node in the blockchain ledger, for example, a certain blockchain ledger a is deployed on blockchain nodes 0 to 4, when the blockchain node 1 needs to be logged off, 5 blockchain nodes can be queried for the blockchain ledger a, through the logging off process, only blockchain nodes 0 and 2 to 4 of the valid node can be enabled, the blockchain node 1 is the invalid node, and the blockchain nodes 0 and 2 to 4 no longer perform heartbeat detection with the blockchain node 1.
Specifically, the BaaS platform server may traverse all blockchain accounts related to the blockchain link points to be logged off through the blockchain proxy node, and log off node information of the blockchain nodes to be logged off, that is, the BaaS platform server may send a log off instruction of the blockchain nodes to be logged off to the blockchain proxy node of the blockchain network, so that the blockchain proxy node logs off node information of the blockchain nodes to be logged off of all blockchain accounts related to the blockchain nodes to be logged off.
S304, calling the resource layer service to cancel the blockchain node to be cancelled in the blockchain network.
In this embodiment, after all blockchain account books related to the blockchain node to be logged off log off node information of the blockchain node to be logged off, the BaaS platform server invokes the resource layer service to log off the blockchain node to be logged off, and specifically, the BaaS platform server may log off Pod of the blockchain node to be logged off (at this time, set the copy number of Pod to 0) by invoking Kubernetes, so as to complete the log off of the blockchain node to be logged off.
It should be noted that, in the process of canceling the blockchain node to be canceled, the node information of the blockchain node to be canceled needs to be canceled by all blockchain account books related to the blockchain node to be canceled first, and then the blockchain node to be canceled is invoked by the resource layer service in the blockchain network.
In addition, considering that the blockchain ledger related to the blockchain point to be logged off may adopt a common-knowledge mechanism of the bayer algorithm, for example, a BFT-Smart common-knowledge mechanism, at least 3f+1 common-knowledge nodes (at least 4) are needed, and if a blockchain ledger has fewer common-knowledge nodes than 3f+1 common-knowledge nodes (at least 4) after logging off the blockchain node to be logged off, the blockchain network may run abnormally, even crash. Therefore, after querying all blockchain accounts related to the blockchain link points to be de-registered according to the de-registration instruction in S302, the method further includes:
judging whether the number of the consensus nodes of any blockchain account book related to the blockchain link points to be logged out meets the minimum number (3f+1) of the consensus nodes required by the account book after the blockchain nodes to be logged out are logged out;
further, if it is determined that the number of the consensus nodes of all the blockchain account books related to the blockchain link points to be logged out meets the minimum number of the consensus nodes required by the account book after the blockchain nodes to be logged out are logged out, the node information of the blockchain nodes to be logged out is logged out of all the blockchain account books related to the blockchain nodes to be logged out;
if the number of the consensus nodes of any blockchain account book related to the blockchain link point to be logged off is determined to not meet the minimum number of the consensus nodes required by the account book after the blockchain node to be logged off is logged off, the registration of the blockchain node to be logged off is not allowed, so that the normal operation of the blockchain network is ensured.
On the basis of any one of the above embodiments, the deployment method of the blockchain node provided in the embodiments of the present application further provides a method for activating a logged-off blockchain node in a blockchain network, as shown in fig. 4, which specifically includes the following steps:
s401, receiving an activation instruction of the logged-off blockchain node.
In this embodiment, when any logged-off blockchain node in the blockchain network needs to be activated, the user may send an activation instruction for the logged-off blockchain node to the BaaS platform server through the Web front end.
S402, calling the resource layer service to create and start the de-registered blockchain node in the blockchain network.
In this embodiment, since the de-registered blockchain node has already registered in the blockchain network, it is only necessary to recall the resource layer service to create and activate the de-registered blockchain node in the blockchain network. The process is similar to S203 above, in which the Pod of the logged-off blockchain node is created by Kubernetes, the blockchain node is created according to the preset blockchain node template, and the configuration is performed according to the identity information of the logged-off blockchain node, so that the creation of the logged-off blockchain node is completed, and then the service of the logged-off blockchain node in the Pod is further started.
S403, synchronizing the blockchain ledger in the blockchain network to the de-registered blockchain node, and activating the de-registered blockchain node.
In this embodiment, after the logged off blockchain node is started, the BaaS platform server may initiate activation of the logged off blockchain node, so that the logged off blockchain node becomes a consensus node again, and the process is similar to S204 described above, specifically, the BaaS platform server may control the logged off blockchain node to synchronize the blockchain ledger in the blockchain network, and after the blockchain ledger synchronization is completed, may control the logged off blockchain node to modify the state to be the consensus node, and update the network topology of the blockchain network.
Based on any of the above embodiments, in this embodiment, information of each blockchain node in the blockchain network may be visually displayed on a display device, where the information of the blockchain node includes at least one of identity information, related ledger wall information, intelligent contract information, and status information of the blockchain node.
Specifically, the interface displayed visually may be as shown in fig. 5, where the interface may display the node name, organization name, and node status of each blockchain node in the blockchain network, may provide a logout operation and a button for newly adding a node, may display all blockchain accounts (including information such as contract name and contract version) related to a blockchain point after clicking the logout operation on a blockchain point, and may update the status of the blockchain node in the interface to "suspend" after completing logout, and may display a button for activating operation at this time so as to activate the blockchain point again. In addition, after clicking a button of the newly added node or a button of the activating operation, all blockchain ledger lists of the blockchain network are displayed for selecting the target blockchain ledgers to be added by the blockchain node to be added or the blockchain node to be activated.
The deployment method of the blockchain node provided by the embodiment can realize the dynamic addition, cancellation and reactivation of the blockchain node by the BaaS platform, can be suitable for any consensus mechanism, in particular for a consensus mechanism based on a Bayesian algorithm, and can invite other participants to carry out blockchain networking on the BaaS platform when networking, and can start 4 blockchain nodes by default when networking, so that a blockchain network can be successfully built no matter whether an invitee agrees to networking or not, and then the blockchain node of the invitee is added in the blockchain network by the deployment method of the blockchain node; the network initiator stores a large amount of redundant data by 3 blockchain nodes which are started more than other participants, so that the storage space is wasted, the deployment cost is increased, the network initiator occupies a plurality of groups of blockchain nodes, the probability that the network initiator wins a vote is higher than that of other participants when the votes are commonly known, and the network initiator can log off the redundant blockchain nodes at the network initiator side through the deployment method of the blockchain nodes (the node number is ensured to meet 3f+1 in the log-off process) along with the joining of the network participants, so that the problems can be solved; in addition, the blockchain nodes can be dynamically deactivated or re-activated for other participants, so that the flexibility and convenience of the BaaS platform for configuring the blockchain network are improved.
