The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning.
Furthermore, the technical features, aspects or characteristics described herein may be combined in any suitable manner in one or more embodiments. It will be readily appreciated by those of skill in the art that the order of the steps or operations of the methods associated with the embodiments provided herein may be varied. Thus, any sequence in the figures and examples is for illustrative purposes only and does not imply a requirement in a certain order unless explicitly stated to require a certain order.
The first embodiment is as follows:
one embodiment of the node processing method based on the block chain of the present invention includes a process of deploying the block chain and a process of running the block chain. The process of the block chain operation, as shown in fig. 1, includes the following steps:
step 102: and detecting the nodes in the block chain.
In a block chain operation scene, the nodes in the block chain can be detected through the servo module, the servo module can be a single daemon thread served by a chain node, and can also be a single process or service except for the independent chain node, the function of the servo module is to monitor and manage the chain node, terminate a designated service thread or process when necessary, and restart or copy the chain node.
The detection mode can be a self-contained function of the link node, and a service for detecting the activity state of the link node can be separately deployed. The starting mode can be spontaneous behavior of the node, and can also be passive triggering of monitoring service.
The rule according to which the detection mode depends includes: service anomaly identification identifier definitions, communication protocols within blockchains, communication protocols across chains, transaction construction containers, authentication algorithms, and the like. Wherein, the node service exception may include: the node service is non-responsive, the phishing algorithm verification is not in accordance with the expected requirement, the consensus algorithm is illegal, the node ip outside the cluster appears in the p2p node list, the cpu utilization rate exceeds the specified threshold value for a certain time, the memory utilization rate exceeds the specified threshold value for a certain time, the disk occupancy rate is not high for a long time or the node service thread occupies too many service ports. The intra-block chain communication protocol is an http protocol based on TCP/IP and a P2P communication technology based on the HTTP protocol; the cross-link communication protocol is that a node is simultaneously used as a common node of two chains, receives the broadcast transaction of the two chains and participates in a consensus algorithm, and the node follows the communication protocols of the two chains simultaneously, and the mode is used for collecting the calculation result of one chain for auditing and verifying; the transaction construction container is used for constructing a transaction by the servo program and submitting the transaction to a specified node to wait for a calculation result; the authentication algorithm comprises the steps of constructing a transaction by using a servo transaction builder, submitting the transaction to a designated node, waiting for the chain consensus where the designated node is located to be finished, taking the consensus result, and verifying whether the calculation result meets the expected result.
Step 104: when the abnormal node service is detected, the abnormal node is copied according to a preset rule, the copied node is connected to the cluster of the block chain, and the external service is carried out.
When one or more nodes are detected to be abnormal in service, starting a self-copying function of the node, copying an agent node of the node, and connecting the agent node to the cluster of the current chain;
checking whether the database of the abnormal node is available, if so, continuing to use the original database to continue the external service; otherwise, initiating a request for synchronous data to the node with normal service, and then serving the node externally, and connecting the node with normal service to the cluster of the current chain for serving the node externally. The duplicated proxy node may be on the current device or on a designated device.
Confirming whether a node is abnormal may include: when one servo module detects that one node is abnormal, p2p broadcasts to the servo modules of other nodes, when the servo modules exceeding a preset number verify that the node is abnormal, the node is considered to be an abnormal node, the preset number can be set according to needs, and if the servo modules can be set to 2/3 or other numbers consider that the node is an abnormal node, the node can be judged to be an abnormal node.
Further, step 104 may include:
step 1042: when the servo module detects that one or more nodes in the block chain have abnormal service, the proxy node of the abnormal node is copied, and the proxy node is connected to the cluster of the current chain. Fig. 2 shows a schematic diagram of a proxy node replicating an exception node. The proxy node is connected to the cluster of the current chain. Checking whether the database of the abnormal node is available, if so, continuing to use the original database to continue the external service; otherwise, initiating a request for synchronous data to the node with normal service and then serving the node with normal service.
Further, step 104 may further include:
step 1044: when the number of the detected abnormal nodes reaches a threshold value, copying the proxy node of each node on the block chain, connecting the proxy node of each node to obtain a virtual chain, checking whether the database of the node on the block chain is available, and if the database is available, continuing to use the original database to continue the external service; otherwise, initiating a request for synchronous data to the node with normal service and then serving the node with normal service. A virtual chain is obtained by copying, and the original block chain is replaced, so that the concurrent processing capacity of the chain is improved. Fig. 3 shows a schematic diagram of a proxy node replicating each node on a blockchain resulting in a virtual chain.
The rules according to which the database is checked include: data validity identification, transaction construction algorithm, authentication algorithm and the like. The data of the database is checked in a mode that after the transaction constructed according to the transaction construction container of the servo module is submitted to a designated node, the transaction data of the Merkel tree structure is stored on a disk of a link point after the consensus is finished, and the servo module can check out the data and compare the data with expected data. Wherein, the data validity mark represents whether the data is valid or not, and the transaction construction algorithm is the construction algorithm used by the transaction constructor; the authentication algorithm is an authentication method for comparing the transaction data taken by the servo module with expected data, and the algorithm is based on an algorithm used by a chain signature, such as an ECDSA elliptic curve digital signature algorithm, a multiple signature method, an RSA algorithm and the like.
Further, the node processing method based on the block chain of the present invention, wherein the process of deploying the block chain, may include the following steps:
step 100: when a single node on the block chain is deployed, a specified number of node clusters are automatically generated according to the configuration file. The positions of the nodes can designate target machines, and node clusters meeting the expected quantity requirements are automatically and intelligently amplified. FIG. 4 shows a schematic diagram of a single node augmented with multiple nodes.
Automatically and intelligently amplifying node clusters meeting the requirement of expected number by means of appointed number or appointed target machines and the like, and avoiding pain points of each node needing manual deployment
As a service, a blockchain is deployed manually in the prior art by manually deploying a plurality of machines or a single machine and a multi-port manner, and manual deployment requires manual modification, which is roughly divided into several steps:
preparing each server user name/password of a node to be deployed → selecting one of the servers to prepare a node executable file → starting a servo service on the selected node (if the servo service is integrated into a chain node program, adding-batch _ default-configuration-yml node 192.168.1.102,192.168.1.xxx, xxx.xxx.xxx.xxx.xxx.xxx.xxx.xxx.xxx.xxx.yml is used to install the specified node and form a cluster.
The consensus algorithm can be a proxy equity Byzantine fault-tolerant algorithm, and the consensus algorithm requires that the number of nodes satisfies n is more than or equal to 3f +1 to satisfy the effectiveness of consensus. The communication protocol in the block chain comprises a http protocol or a https protocol based on a TCP/IP and a p2p communication technology, the invention is not limited to a consensus algorithm, if the number n of block chain link points of other PBFT consensus algorithms is adopted, n is more than or equal to 3f + 1; if a workload certification mechanism (PoW), a rights and interests certification (PoS) or a proxy rights and interests certification (DPoS) g consensus algorithm is adopted, the number n of nodes needs to satisfy that n is more than or equal to 2f + 1.
In the embodiment of the present invention, the configuration file may be set according to a consensus algorithm and a rule based on a specific consensus algorithm, such as whether a node needs to be verified by a proxy rights-of-interest byzantine fault-tolerant algorithm (DS-PBFT), whether the node needs to pass a check label of an initial node, a communication protocol in a block chain, and the like.
The number of the nodes can be set according to the requirement of a consensus algorithm, for example, a chain of a 'agent rights Byzantine fault-tolerant algorithm (DS-PBFT)' is adopted, the nodes are automatically adjusted according to the rule setting, and the automatically amplified nodes need to be checked if the nodes are verification nodes, and are not checked if the nodes are non-verification nodes.
The difference between the automatic amplification deployment of the embodiment of the invention and the multiple deployment in the prior art is that the configuration of each node is automatically generated, and the node cluster meeting the requirement of the expected number is automatically and intelligently amplified by the modes of specifying the number, specifying a target machine and the like, so that the pain point of each node needing manual deployment is avoided.
And automatically and intelligently amplifying the deployment chain nodes, namely, automatically deploying and building a chain of nodes meeting the specified rule quantity by utilizing the specified rule or server information of the servo module, and dynamically adjusting the verification nodes according to the self-defined rule. In one embodiment, a node may be designated as a verification node and the rest as non-verification nodes.
The node processing method based on the block chain comprises a block chain deploying process and a block chain running process. Another embodiment, as shown in fig. 5, comprises the steps of:
step 502: and deploying the block chain, and automatically generating a specified number of node clusters according to the configuration file when a single node on the block chain is deployed.
Step 504: and detecting the nodes in the block chain. In an operation scene, detecting nodes in a block chain, and searching nodes with abnormal service.
Step 506: when the abnormal service of the node is detected, the agent node of the abnormal node is copied, and the agent node is connected to the cluster of the current chain. Checking whether the database of the abnormal node is available, if so, continuing to use the original database to continue the external service; otherwise, initiating a request for synchronous data to the node with normal service and then serving the node with normal service.
Step 508: and judging whether the number of the abnormal nodes reaches a threshold value, if so, turning to a step 510, and otherwise, turning to a step 504.
Step 510: and copying the proxy node of each node on the block chain, and connecting the proxy nodes of each node to obtain a virtual chain. Checking whether the database of the node on the block chain is available, if so, continuing to use the original database to continue the external service; otherwise, initiating a request for synchronous data to the node with normal service and then serving the node with normal service.
The method comprises the steps of copying abnormal nodes according to a preset rule when abnormal node service is detected, and connecting the copied nodes to a cluster of a block chain for external service.
