Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data processing method based on the block chain can be applied to the application environment shown in fig. 1. The application environment includes a terminal 102 and a node 104 in a blockchain network. The terminal 102 and the node 104 communicate through a network, and each node in the blockchain network also communicates through the network. The user terminal 102 may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The nodes 104 may be implemented as individual servers or as a server cluster of multiple servers. Each type of service container in the node 104 determines service containers of other types of the at least two types of service containers and services registered in a service registry container; each service is used to perform a processing element of the data processing logic sequence of node 104. When the node 104 acquires the data to be stored from the terminal 102, the data is processed according to the corresponding service through the service containers of the corresponding class according to the data processing logic sequence of the node 104. After reaching consensus with other nodes in the blockchain network, the node 104 stores the data to be stored through a service container providing storage service in at least two types of service containers. Those skilled in the art will understand that the application environment shown in fig. 1 is only a part of the scenario related to the present application, and does not constitute a limitation to the application environment of the present application.
In one embodiment, as shown in fig. 2, a data processing method based on a blockchain is provided, which is described by taking the method as an example applied to a node 104 in a blockchain network in fig. 1, and includes the following steps:
s202, each type of service container determines other types of service containers in the at least two types of service containers and services registered in a service registration center container; each service is for performing a processing element of the node data processing logic sequence.
Wherein a container is a process that processes data. A service registry container is a type of registration container used to register services, discover services, and check the health status of services. The service container is a container in which a module is operated to provide a service corresponding to the module. A service is a function provided by a module, such as a service that provides at least a portion of the functionality in a blockchain, a service that implements links of a transaction, or a service that implements links of a social interaction.
A blockchain network is a carrier and organization way to run blockchain technology. Block chaining (bt) is a technology of internet database, also called distributed book technology. The method is characterized by decentralization, openness and transparency, and each person can participate in data recording. The blockchain technology is a brand new distributed infrastructure and computing mode that uses blockchain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to secure data transmission and access, and uses intelligent contracts composed of automated script codes to program and manipulate data.
In the embodiment of the invention, each node in the block chain network runs a service registration center container and at least two types of service containers. Each type of service container on the node may register the service with the service registry container, and each type of service container may further determine services for which other ones of the at least two types of service containers are registered with the service registry container.
In one embodiment, the blockchain network may have at least three nodes, and the nodes may communicate with each other through the network. At least one service registry container and at least two types of service containers are operated in each node, and the number of each type of service container can be one or more than one. Each type of service container is independent, and when each type of service container needs the service of other service containers in at least two types of service containers, the service registered by each type of service container in the service registration center container can be acquired.
Referring to fig. 3, in one embodiment, a blockchain network exists with nodes A, B, C and D communicating between nodes A, B, C and D through a P2P container. And a service registration center container and six types of service containers are respectively operated on each node. The six types of service containers are respectively a P2P (Peer-to-Peer) container, a node container, a cache container, an intelligent contract container, a storage container and a consensus container. Among other things, the P2P container may provide services for communication between nodes in a blockchain network. The node container can provide a service for verifying the data to be stored sent by the terminal and broadcasting the data to be stored through the P2P container. The cache container may provide a service to store temporary data or frequently accessed data. The intelligent contract container can provide a service for generating an intelligent contract simulation result according to the computer protocol and the data to be stored. The storage container may provide a service of storing the blocks generated by the data to be stored in a hard disk or a database. The consensus container can provide a service of consensus among all nodes in the block chain network through consensus operation.
And S204, when the data to be stored is obtained, processing the data according to the corresponding service through the service containers of the corresponding class according to the node data processing logic sequence.
In particular, the terminal may send data to be stored to nodes in the blockchain network. When the node acquires the data to be stored, the data to be stored can be processed according to the corresponding service through the service containers of the corresponding classes according to the logical sequence of the node data processing.
In one embodiment, the data to be stored sent by the terminal to the nodes in the blockchain network may be transaction data. The transaction data may specifically include the name of the transaction, the time of the transaction, the amount of resource transfer, the number of transactions, and the account names of the two parties to the transaction. The node can verify the validity of the transaction data, specifically, verify the validity of data information, the accuracy of the transaction data and the like. The transaction data which passes the validity verification is the transaction data which is complete in record, correct and has not been tampered.
And S206, after the node agrees with other nodes in the block chain network, storing the data to be stored through a service container which provides storage service in at least two types of service containers.
Specifically, the processing result after data processing is performed according to the corresponding service through the service container of the corresponding class is sent to the block chain network for consensus operation. When the node agrees with other nodes in the block chain network, the node stores the data to be stored locally through a service container which provides storage service in at least two types of service containers.
In one embodiment, the consensus operation in the blockchain network may be implemented by a consensus algorithm. Common consensus algorithms in the blockchain network include POW (Proof of Work), POS (Proof of interest), DPOS (cleared Proof of interest), PBFT (Practical Byzantine Fault Tolerance algorithm), and the like. The embodiment of the application does not limit the consensus algorithm adopted by the consensus node.
In one embodiment, a node may have a cache container and a storage container running thereon. The cache container can cache data processing results sent by other nodes in the blockchain network, and the data processing results in the cache container are stored in the storage container after the data processing results in the cache container reach a consensus in the blockchain network. Therefore, when the block chain network processes a large amount of data to be stored, the burden of the storage container can be greatly reduced, and the storage speed is improved.
In the above data processing method based on the blockchain, the services provided by each type of service container are registered to the service registration center container. Therefore, when the data to be stored is acquired, the node can acquire the corresponding service provided by the corresponding class through the service registry container when executing each processing loop of the node data processing logic sequence. And when the node agrees with other nodes in the block chain network, the storage service is acquired through the service registration center container, and the data to be stored is stored. Thus, the service required by each service container is acquired through the service registry container. Each function module in the traditional block chain is packaged into a service container which can independently run respective service in a single node, each service container is independent, and each service container can be flexibly expanded, so that the service efficiency of the block chain network is greatly improved. In addition, each module is packaged into independently-operated service, and is in an extremely-low coupling state with other modules, so that the version iterative development and maintenance of each module in the follow-up process become easier and the cost is lower.
In one embodiment, in step S202, that is, each class of service container determines the service container of the other class of service containers, and before the step of serving the service registered by the registry container, the method for processing data based on the blockchain further includes: acquiring a service registration center container mirror image and a service container mirror image; mirror-image running of a service registration center container to form a service registration center container, and mirror-image running of the service container to form a service container; the service container registers the corresponding service in the service registry container.
The mirror image is a file storage form and is a type of redundancy, and data on one disk has an identical copy on another disk, namely the mirror image. Common Image file formats include ISO (Open Systems interconnection), BIN (Binary file), IMG (Image file), TAO (Track-At-one), DAO (Disk-At-one), and the like. The embodiment of the application does not limit the format of the mirror image file.
In particular, a node in a blockchain network may obtain a service registry container image and a service container image. Furthermore, the node may run the service registry container mirror as a service registry container and the service container mirror as a service container by running the technology of the program. After the service registry container and the service container are both started, the service container can register corresponding services in the service registry container.
In one embodiment, the technology for running the program may specifically be a Docker technology. The Docker is an open-source application container engine, and related applications and dependency packages can be packaged into a portable image through the Docker technology and then distributed to computer equipment. The Docker technology is characterized in that the containers operated by the Docker technology do not have any interfaces with each other. In addition, the technology for running the program may specifically be Tomcat technology. Tomcat is a Web (World Wide Web) application server. The Tomcat technique is characterized in that the vessels operated by the Tomcat technique are independent of each other.
In one embodiment, the service registry container may be implemented by the Consul technology. Consul is a service grid solution. Consul is a distributed, highly available system. Consul provides a fully functional control plane. Consul is mainly characterized in that: service discovery, health check, key value storage, security service communication and multiple data centers. The service registry container may also be embodied in Zookeeper technology. Zookeeper is a highly available, high-performance and consistent open source coordination service designed for distributed applications, is a basic component of a big data distributed cluster, and provides distributed lock service for the cluster. The service registry container may also be implemented in particular by Etcd technology. Etcd is a distributed KV (Key-Value, Key-Value pair) storage facility. Etcd is characterized in that: the method has the advantages of consistency, high performance and high availability.
In the above embodiment, the service registry container is obtained, and the service registry container is operated as the service registry container in a mirror image manner, so that the service registry is provided for the node. By acquiring the mirror image and the service container mirror image, the service container mirror image is operated to be a service container, so that each service container can be operated independently. And registering the service provided by each service container to the service registry container, so that each service container can acquire the corresponding service from the service registry container.
In one embodiment, the node may determine the number of each of the at least two types of service containers based on the service performance of each type of service container. Specifically, the number of each type of service container running on the node can be flexibly selected according to the performance of each type of service container. For example, a service registry container and six types of service containers are operated on the node. The six types of service containers are respectively a P2P container, a node container, a cache container, an intelligent contract container, a storage container and a consensus container. The node container has lower efficiency of processing data than other five types of service containers. Then, more than one node container can be run on the node, and the more than one node container can process data simultaneously, so that the data processing efficiency of the whole block chain network can be improved. The number of each type of container can be preset, or a plurality of same service containers can be automatically started by detecting the performance of each type of service container.
In an embodiment, the step S202, that is, the step of determining, by each service container, a service container of another class of the at least two classes of service containers and a service registered in the service registry container specifically includes: each service container determines a service identifier of a service to be called; the service identifier is the service identifier of the service registered by the service container of other types in the at least two types of service containers in the service registration center container; and each service container inquires services corresponding to the service identifications from the service registration center container according to the service identifications.
The service identifier is an identifier used for uniquely determining the service provided by the service container, and may specifically include a character string of at least one character of letters, numbers, and symbols.
Specifically, each type of service container running on a node can determine the service identifier of the service required to be called by the current data processing link. Furthermore, each type of service container can inquire the service registered in the service registry container by the service container from the service registry container according to the service identifier, and the service corresponding to the service identifier is registered in the service registry container. And the subsequent service container can call the corresponding service container for providing the service according to the inquired service to perform data processing.
In one embodiment, the service identification may determine services provided by more than one homogeneous service container. For example, three node containers may be run on a node, and since the services provided by the three node containers are the same, the services provided by the three node containers may be marked by the same service identifier. When other service containers in the node call the service of the node container, any one of the three node containers can be acquired as a provider of the service in the service registry container through the service identifier.
In the embodiment, the service identifier of the service registered in the service registration center container by the service container of the other class of the at least two classes of service containers can quickly and accurately inquire the service corresponding to the service identifier in the service registration center container when the service container of the other class of the at least two classes of service containers calls the service, so that the service inquiry time is saved.
In one embodiment, the method for processing data based on block chains further comprises: the service registration center container monitors the state of the service container; when at least one service container is in an abnormal state, the service registration center container periodically checks the state of the abnormal service container; and when the abnormal service container is recovered to the normal state, informing the service container needing to call the service.
Specifically, the service registry running on the node may detect a state of the service container running on the node, and when at least one of the at least two types of service containers running on the node is in an abnormal state, the service registry container running on the node may periodically check the state of the abnormal service container. When the service registration center container detects that the abnormal service container is recovered to the normal state, the service container needing to call the service can be informed to call the service.
In an embodiment, the abnormal state of the service container may be specifically a failed start-up of the service container when the service container is started, or a suspended service caused by an uncontrollable external factor received during the operation of the service container, for example, a hardware damage of the service container due to a natural disaster. In addition, the abnormal state of the service container may also be a software fault occurring during the operation of the service container, for example, data of the service container is tampered by a human being.
In one embodiment, when the service registry container detects that at least one service container is in an abnormal state, the service registry container may check the health status of the abnormal service container immediately, or after detecting the abnormality, the service registry container may check the health status of the abnormal service container according to a preset time, for example, after 5 minutes.
In the above embodiment, the service registration center container periodically checks the health state of the abnormal service container, so that after the service container returns to the normal state, the service provided by the recovered service container can be timely called by the service calling party, thereby ensuring the timeliness of data processing and further improving the service efficiency of the block chain network.
In one embodiment, the node may further comprise at least one service container of the same type as the anomalous server, and the service registry container may monitor the status of the service container. When the service registry container detects that the abnormal service container is not recovered to a normal state, the service registry container can determine at least one service container which is similar to the abnormal service container. The service registry container may notify service containers that need to invoke services, and determine a service container to invoke services from at least one service container that is the same as the abnormal service container.
Referring to FIG. 4, in one embodiment, a service registry container, two node containers, and three intelligent contract containers are run on a node. When the intelligent contract container 3 is in an abnormal state, the service registry container may inform the abnormal state of the intelligent contract container 3 of the node container 1 and/or the node container 2 which called the intelligent contract container 3 service, and the node container 1 and the node container 2 do not call the intelligent contract container 3 any more subsequently. Because the services provided by the intelligent contract container 1 and the intelligent contract container 2 are the same as the intelligent contract container 3, the node container 1 and/or the node container 2 can invoke the services of the intelligent contract container 1 or the intelligent contract container 2 according to the condition obtained by the container query in the service registration center, thereby ensuring the normal invocation of the services.
In an embodiment, step S204, that is, when the data to be stored is obtained, according to the logical sequence of node data processing, the step of performing data processing according to the corresponding service through the service container of the corresponding class specifically includes: when data to be stored are obtained, determining a data processing link in a node data processing logic sequence where a node is currently located; according to the data processing link where the node is currently located, searching services provided by service containers of the class corresponding to the data processing link in a service registration center container; and calling at least one service container in the class corresponding to the service to process the data to be stored.
Specifically, the processing of the data to be stored by the node may be sequentially performed according to the logical order of the node data processing. When the node acquires the data to be stored, the node can determine the data processing link in the node data processing logic sequence where the node is located currently. According to the data processing link where the node is currently located, the node can search the service provided by the service container of the class corresponding to the data processing link in the service registration center container. Furthermore, the node can call at least one service container in the class corresponding to the service to process the data to be stored.
In one embodiment, the processing of the data to be stored acquired from the terminal may include broadcasting the data to be stored, verifying the validity of the data to be stored, processing the valid data to be stored through a computer protocol to generate an intelligent contract simulation result, caching the intelligent contract simulation result, consensus the intelligent contract simulation result, and storing the consensus data.
In the above embodiment, the service required by the current data processing link can be quickly determined by determining the data processing link in the logical sequence of the node data processing in which the node is currently located. Furthermore, the services provided by the service containers corresponding to the current data processing link can be quickly and accurately found in the service registration center container. Therefore, the service container corresponding to the service can be called to process the data to be stored.
In one embodiment, in step S206, that is, after reaching a consensus with other nodes in the blockchain network, before the step of storing the data to be stored by using a service container providing a storage service in at least two types of service containers, the method for processing data based on blockchain further includes: acquiring processing results fed back by other nodes in the block chain network; and performing consensus operation on the processing result in the block chain network through at least one service container of the corresponding class of the consensus service registered in the service registration center container.
Specifically, other nodes in the blockchain network may process the data to be stored, and feed back the processing result to the node. The node can obtain the processing result fed back by other nodes in the blockchain network and locally cache the processing result. At least one service container of the corresponding class of the consensus service registered in the service registration center container can send the processing result of the local cache to the block chain network for consensus operation.
In one embodiment, a node in the blockchain network may vote for the processing result of the data to be stored. And when more than half of the nodes in the block chain network process the data to be stored and obtain consistent processing results, the consensus is passed. When more than half of the nodes do not exist in the block chain network and the processing results obtained by processing the data to be stored are consistent, the data to be stored needs to be pulled again for calculation until more than half of the nodes exist in the block chain network and the processing results obtained by processing the data to be stored are consistent.
In the above embodiment, the processing results fed back by other nodes in the blockchain network are sent to the blockchain network, and the consensus operation is performed on the processing results through at least one service container of the corresponding class of the consensus service registered in the service registration center container, so that the consistency of data of each node in the blockchain network is ensured.
In an embodiment, the step S206, that is, after reaching a consensus with other nodes in the blockchain network, of storing the data to be stored through a service container providing a storage service in at least two types of service containers specifically includes: when the common identification is achieved with other nodes in the block chain network, generating a block by the data related to the data to be stored; searching a service container providing storage service in a service registration center container; and storing the block through the searched storage service provided by the service container.
Specifically, after the processing result of the data to be stored agrees with other nodes in the block chain network, the nodes may pack the data to be stored and the processing result of the data to be stored into blocks. Further, the node may look up a service container that provides storage services in the service registry container. The nodes may store the blocks locally through the storage services provided by the container.
In the above embodiment, the data related to the data to be stored is generated into the block, so that the data related to the data to be stored is exactly in the same block. Through the storage service registered in the service registration center, the newly generated blocks can be rapidly stored, and the service efficiency of the block chain network is further improved.
As shown in fig. 5, in a specific embodiment, the data processing method based on the block chain includes the following steps:
