Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an information processing method, device, node management unit and node. Background Art

[0002] Blockchain technology, also known as distributed ledger technology, is a technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Blockchain technology has been widely used in many fields because of its decentralization, openness and transparency, each computing device can participate in database records, and data can be quickly synchronized between computing devices.

[0003] At present, the test methods for changes to smart contracts and applications corresponding to existing blockchain networks include: the blockchain test network deploys the changed applications or smart contracts and adds a block reading interface to the traditional blockchain network to obtain the blockchain environment and block data in the production environment (before the change, i.e. the current version) to build a node for the blockchain network to be tested. For more information about the blockchain test network, see Figure 1 .

[0004] However, in existing blockchain testing solutions, the generation environment and the test environment are separated, such as Figure 2 As shown, it is not conducive to resource sharing and may lead to test deviation and low test accuracy.

[0449] Wherein, copying the production area information to the test area includes: using a preset method to copy the production area information to the test area; wherein, the preset method includes at least one of the following methods: copying the production area data; copying the access link of the production area data.

[0450] In an embodiment of the present invention, when the third sub-information indicates that the node type indicated by the second type information is not a newly added type, after changing the node type according to the second indication information, it also includes: synchronizing chain block data with nodes of the same node type.

[0451] Furthermore, after changing the node type according to the second indication information, the method further includes: updating the contract version.

[0452] Furthermore, the method further includes: receiving a block synchronization adjustment instruction sent by the PMU; and adjusting the block data synchronization operation according to the block synchronization adjustment instruction.

[0453] The receiving of the second indication information sent by the node management unit PMU includes: receiving the first sub-information sent by the PMU; feeding back the first response information to the PMU according to the first sub-information; and receiving the second sub-information sent by the PMU according to the first response information.

[0454] Corresponding to the following new node joining process, the method also includes: receiving fourth indication information sent by the PMU; marking the node type of the node as a production type or a test type, and installing a contract according to the fourth indication information; and adding result information to the PMU feedback node; wherein the fourth indication information includes fourth sub-information for indicating that the node type is marked as a production type or a test type and fifth sub-information for indicating the contract to be installed.

[0455] The receiving of the fourth indication information sent by the PMU includes: receiving fourth sub-information sent by the PMU; feeding back second response information to the PMU according to the fourth sub-information; and receiving fifth sub-information sent by the PMU according to the second response information.

[0456] Specifically, marking the node type of the node as a production type or a test type and installing the contract according to the fourth indication information includes: marking the node type of the node as a production type or a test type according to the fourth sub-information; and installing the contract according to the fifth sub-information.

[0457] Furthermore, after marking the node type of the node as a production type or a test type according to the fourth indication information and installing the contract, it also includes: when there are nodes of the same node type, synchronizing chain block data between nodes of the same node type.

[0458] Corresponding to the following node registration process, the method further includes: receiving a node status query request sent by the PMU; and feeding back the node status and node resource information of the node to the PMU according to the node status query request.

[0459] Corresponding to the following test process, the method further includes: receiving test data sent by the PMU; verifying the signature data in the test data; and executing the test cases in the test data if the verification passes.

[0460] Corresponding to the following contract installation and / or upgrade process, the method also includes: receiving contract processing instruction information sent by the PMU; verifying the signature data in the contract processing instruction information; if the verification passes, installing and / or updating the contract according to the contract program file in the contract processing instruction information, and feeding back processing response information to the PMU based on the processing result.

[0461] The information processing method provided by the embodiment of the present invention is further described below in conjunction with multiple sides such as a node management unit and a node, wherein the above-mentioned contract is hereinafter referred to as a smart contract, and the above-mentioned node may correspond to each node involved below, which is not limited here.

[0462] First of all, the blockchain network is a technical infrastructure that provides ledger and smart contract services for applications. First, smart contracts are used to generate transactions, which are then distributed to each node in the network and recorded on each node's copy of the ledger and cannot be tampered with.

[0463] In most cases, multiple organizations come together as a consortium to form a network. A blockchain network is mainly composed of a group of nodes. Nodes host ledgers, smart contracts, and policies. An organization joins or exits a blockchain network by deploying or revoking nodes. Therefore, nodes can be considered as physical devices of a blockchain network, while ledgers, smart contracts, policies, etc. are logical units of the blockchain.

[0464] Based on the above, in view of the above technical problems, an embodiment of the present invention provides an information processing method, which can be based on Figure 5 and Figure 6 The blockchain network implementation shown in FIG. Figure 5 , through each organization to increase the production and testing of two types of nodes, such as Figure 6 , generating multiple logically independent virtual blockchain networks in a unified physical blockchain. The production nodes form a unique blockchain production environment, and the test nodes form multiple virtual environments for different purposes, such as performance testing and pre-launch test networks for new versions of smart contracts.

[0465] Specifically, an organization can join the following types of nodes:

[0466] 1. Add production nodes and test nodes at the same time. In this case, there are two configurations for the number of production nodes and test nodes: static configuration, which refers to a fixed number of production nodes and test nodes or a fixed ratio between production nodes and test nodes; and dynamic configuration, which is dynamically adjusted according to the access traffic of the production environment and the test environment.

[0467] 2. Join only production nodes. In this case, from the perspective of the organization, this blockchain is a production blockchain network.

[0468] 3. Only join the test node. In this case, from the perspective of the organization, this blockchain is a test blockchain network. Currently, an online test blockchain network is provided, which is conducive to guiding organizations to use the blockchain network.

[0469] Among them, multiple logical blockchain networks follow the following technical requirements:

[0470] 1. The test blockchain network produced by the mirror follows the relevant smart contracts and policies of the production environment (defining the permissions of each organization to join the blockchain network, etc.);

[0471] 2. The test blockchain network produced by the mirror can read the block data of the nodes in the production environment to build blocks for testing. The block reading can read the genesis block or any intermediate block according to the needs;

[0472] 3. The node can be a production node or a test node. When the node is converted between a production node and a test node, the blockchain data of its production environment is permanently valid. When it is restored from a test node to a production node, it is only necessary to upload the production transaction data of the period of time as a test node to the chain. The test chain data of the test node can be retained or deleted according to the storage status of the node. The data of the test chain and the production chain are strictly separated.

[0473] In addition, in order to realize the above production and test integration of blockchain network, it is necessary to add a Peer Management Unit (PMU) to the existing blockchain network. PMU is a logical functional unit, which can add related functions or new functional modules to the current blockchain network management tool. PMU mainly realizes the following functions:

[0474] (1) Node registration;

[0475] (2) Node configuration;

[0476] (3) Smart contract management;

[0477] (4) Functions such as switching of production test networks.

[0478] Among them, PMU is only responsible for the management process of the node, and does not participate in the business processes such as the status query and on-chain transaction of the blockchain network, and does not change the channels, endorsement strategies, smart contracts and configuration and functions of the application programs of the existing blockchain network. This has little impact on the existing blockchain network itself, and is convenient for the subsequent upgrade and implementation of the blockchain network.

[0479] The blockchain network channel needs to add a type field to indicate the production or test network, and the data storage on the node needs to distinguish between the production area and the test area.

[0480] Two information registries need to be added to the PMU, one is the smart contract registry (SCR) and the other is the peer state registry (PSR). For efficiency reasons, the PMU can store the index information of the SCR and PSR. The index information can only include the code, name, and channel fields.

[0481] The SCR includes but is not limited to the following fields:

[0482] Table 1 Smart Contract Registry

[0483]

[0484] PSR contains but is not limited to the following fields:

[0485] Table 2 Node status registration table

[0486]

[0487]

[0488] The logical architecture of the node after adding the PMU unit can be seen in Figure 7 , where the node management unit technology implementation requirements are as follows:

[0489] a) The node management unit can produce multiple instances in the blockchain network. Generally, each organization in the blockchain needs to install an instance of PMU to manage the nodes and smart contracts belonging to the organization. PMU changes the production and test type of the node by adjusting the configuration parameters of the blockchain system; including the storage configuration of the linked list, certificate configuration, etc.

[0490] b) The node management unit should store the node registry and smart contract registry as well as the certificate issued by the organization (the certificate issuance process is generally that the PMU of each organization generates a public-private key pair and provides the public key and related PMU information to request the affiliated organization to sign), so as to determine the organizational affiliation of the PMU. At the same time, in accordance with the certificate and member management requirements of the blockchain network, the PMU certificate needs to be broadcast to each node and stored in the member service directory of each node. In this way, each node of the organization can allow the PMU to access and control through certificate verification to change the configuration parameters of the node, so as to achieve the function of the PMU setting the node type and reading the block data from the production area. The specific technical implementation is described in conjunction with the following processes.

[0491] The above integers can be understood as signatures. Figure 7 The chain block directory and database access parameters in the blockchain account book include the chain block and the world state. In the implementation, the chain block is the file system, and the world state is the database. Therefore, to store the blockchain, it is necessary to configure its related file directory or database access parameters to store the blockchain account book.

[0492] The blockchain organizational structure after joining the PMU unit can be found in Figure 8 , Among them, PMU does not participate in the transaction query and on-chain business processes of the blockchain, and serves as the node management unit of each organization.

[0493] The following is an example of an information processing method provided by an embodiment of the present invention.

[0494] Example 1: Smart contract registration process, such as Fig. 9 As shown:

[0495] The organization administrator provides a request to register a smart contract to the PMU and provides the contract name (corresponding to the PMU receiving the contract identifier); the PMU checks whether it is a new smart contract or a new version (corresponding to the PMU determining whether it is a registered version of the contract based on the contract identifier); if so, register it on the SCR (corresponding to recording the contract corresponding to the contract identifier in the contract registration table to obtain the record information corresponding to the contract identifier); if not, obtain the smart contract information from the SCR (corresponding to obtaining the record information corresponding to the contract identifier from the contract registration table);

[0496] The organization administrator provides the smart contract program and test set (i.e., the contract program and test set corresponding to the contract identifier mentioned above) to the PMU, and the PMU determines the version number of the smart contract program and test set (the version number can be expressed as a version number or timestamp that increases from 1), and then registers the smart contract program and test set on the SCR. Then, the PMU confirms the completion of the registration and returns the version information to the organization administrator. Specifically, the technical implementation requirements involved are as follows:

[0497] The content of the smart contract is shown in Table 2. It can be stored in a database or configuration file inside or outside the PMU.

[0498] a) To ensure the tamper-proof requirements of smart contracts, when PMU stores smart contracts, it can use its storage content of PMU for signing, and when reading or using peer nodes (peer nodes are a type of block nodes, corresponding to the Peer appearing in the text, translated as peer nodes, referred to as nodes), the PMU certificate can be called for verification to maintain the legitimacy of smart contract data; the signature data can be stored in a column in the smart contract registry or in an independent table or file.

[0499] b) PMU encapsulates smart contracts and provides external access interfaces such as adding, modifying, deleting, and querying. The data returned in the query interface includes smart contract registry information and signature data, allowing external nodes to verify the signature.

[0500] c) Smart contracts include program files and test scripts, so the original data for signing a smart contract can be in the following format:

[0501] Smart contract number Note 1 + smart contract name + SHA1[program file] + SHA1[test file 1] + … + SHA1[test file n]

[0502] Note 1: The format of signature data is bytecode, so both string and numeric types need to be converted to bytecode. For example, A is encoded in bytecode 0x41, B is encoded in 0x42, ..., so "ABC" is converted to bytecode as byte[] = {0x41, 0x42, 0x43}. Generally, the program can implement String.getBytes() to complete the above conversion.

[0503] Example 2: Node registration process, such as Fig.10 As shown:

[0504] The organization administrator provides the node information to the PMU, and the PMU checks whether the corresponding node is available (corresponding to the above-mentioned sending of a node status query request to the third node according to the node information of the third node when the node information of the third node is received), the node Peer returns the status and node resource information to the PMU (corresponding to the above-mentioned receiving the node status and node resource information fed back by the third node according to the node status query request), and the PMU registers the node information to the PSR (corresponding to the above-mentioned recording of the node information of the third node in the node registration table PSR when the node status and node resource information indicate that the third node can be used), and then completes the registration and feeds back to the organization administrator that the node status is available (corresponding to the above-mentioned display that the node status of the third node is available).

[0505] The technical implementation requirements of the node registry are the same as those of the smart contract. The source data of its signature is:

[0506] Node number + node address + node status + channel + organization + smart contract number 1 + ... smart contract number n.

[0507] Example 3: A new node joins the blockchain (production or testing) process, such as Fig.11 As shown:

[0508] The organization administrator provides a request to join the node to the production or test network of the specified channel, and the PMU obtains the node information from the PSR and the smart contract information from the SCR accordingly (corresponding to obtaining the registry information of the second node from the node registry PSR according to the identification information of the second node in the third indication information, and obtaining the information of the contract to be installed from the contract registry); then the PMU notifies the available nodes to join the specified channel (corresponding to sending the fourth sub-information to the second node according to the third indication information); the available nodes run the instruction to join the channel and join the specified channel (corresponding to marking the node type of the node as a production type or a test type according to the fourth sub-information); then the PMU instructs the available nodes to install The smart contract (corresponding to the above-mentioned receiving the second response information fed back by the second node according to the fourth sub-information; sending the fifth sub-information to the second node according to the second response information), the available node installs the smart contract accordingly (corresponding to the above-mentioned installation of the contract according to the fifth sub-information); then the available node returns the result to the PMU (corresponding to the above-mentioned feedback of the node joining result information to the PMU), and the PMU updates the node status and smart contract version information accordingly (corresponding to the above-mentioned updating of the node information of the second node according to the node joining result information, and recording it in the node registry PSR); further, the PMU notifies the organization administrator to complete the joining of the new node (corresponding to the above-mentioned display of the node joining result information).

[0509] In addition, when there is already a node in the designated channel to which the available node belongs, chain block synchronization is performed (corresponding to the above-mentioned case where there are nodes of the same node type, chain block data synchronization is performed between nodes of the same node type).

[0510] in:

[0511] a) The process of adding a new node to the production environment or the test environment is the same.

[0512] b) This example involves the communication between the PMU and the node, the modification of the registry information, the addition of blockchain instructions, the installation of smart contracts, and the synchronization of data between nodes. At the same time, the synchronization between nodes is an asynchronous process. Depending on the difference between the blocks of the newly installed or connected nodes and the existing node blocks, the data synchronization time may last for several minutes or hours.

[0513] c) The Peer node can verify the certificate information of the PMU to confirm that the PMU unit and the Peer node belong to the same organization and have the authority to operate the Peer node. Before installing the smart contract, the Peer node needs to confirm the signature information of the smart contract to ensure that the smart contract has not been tampered with to ensure the correctness of the smart contract.

[0514] Example 4: Node ownership change process, adding nodes from the blockchain production network to the test network. Fig.12 As shown:

[0515] The organization administrator provides the PMU with an instruction to add the node to the test area. The PMU obtains the node information from the PSR accordingly, and then instructs the designated node to exit the production channel (corresponding to the above-mentioned acquisition of the registry information of the first node from the node registry PSR according to the identification information of the first node in the first indication information when the first indication information is received; and sending the first sub-information to the first node according to the IP address information in the registry information); after receiving the instruction, the designated node runs the channel instruction, exits the production channel (corresponding to the above-mentioned deletion of the first type of information according to the first sub-information in the second indication information, and feedback of the first response information to the PMU), and copies the production area data to the test area (corresponding to the above-mentioned copying of the production area information to the test area after deleting the first type of information and before adding the second type of information); then the PMU instructs the designated node to join the test channel (corresponding to the above-mentioned receipt of the first node root According to the first response information fed back by the first sub-information; according to the first response information, the second sub-information is sent to the first node), the designated node runs channel signaling, creates or joins the designated test channel (corresponding to the above-mentioned receiving the second sub-information sent by the PMU according to the first response information, and adding the second type of information according to the second sub-information), and performs smart contract version upgrade (corresponding to the above-mentioned updating of the contract version after changing the node type according to the second indication information), updates the smart contract on the channel, and returns the result to the PMU (corresponding to the above-mentioned feedback of the node change result information to the PMU); the PMU updates the node information accordingly (corresponding to the above-mentioned updating of the node information of the first node according to the node change result information, and recording it in the node registry PSR), and then the PMU notifies the organization administrator to complete the node change (corresponding to the above-mentioned display of the node change result information).

[0516] In addition, when a node already exists in the test channel to which the designated node belongs, chain block synchronization is performed (corresponding to the above-mentioned situation in which the third sub-information indicates that the node type indicated by the second type information is not a newly added type, after the node type is changed according to the second indication information, chain block data synchronization is performed between nodes of the same node type).

[0517] The PMU can also determine that if a new test channel is created, block consistency is checked (corresponding to the above-mentioned confirmation of whether the nodes under the newly added node type meet the block consistency conditions after a preset time after confirming the existence of the newly added node type; if not, a block synchronization adjustment instruction is sent to the nodes under the newly added node type to control the nodes under the newly added node type to meet the block consistency conditions).

[0518] Regarding checking block consistency, PMU can perform block consistency check after confirming the existence of a new channel for a period of time; it can be performed according to the chain block directory (block number and sequence number) and synchronize the inconsistent ones.

[0519] The node information updated by the PMU may specifically include the channel to which the node joins and the corresponding contract information.

[0520] It should be noted that in this solution, after a node joins a channel, it can broadcast to all nodes under the management of the PMU to synchronize the chain block data.

[0521] Specifically, the technical implementation requirements of the node change process are as follows:

[0522] a) If the test area nodes are added to the production area, the data replication process and block consistency check process may not be included.

[0523] b) The above process can add one or more nodes from the production area to the test area at the same time. There are two situations. One is to join the existing test area channel, which may not include the data replication involved above (i.e. copying the production area data to Fig.12 The blockchain test (indicates the blockchain and the test type) process and the block consistency check process in the . Only when a new test channel is created (such as a new version of smart contract testing), it is necessary to copy the block data from the production area and check the data consistency. Specifically, the PMU can inform the node whether it is a new channel.

[0524] c) The purpose of block data consistency check is to avoid data inconsistency when batch nodes are traded after joining the test area from the production area. As mentioned above, block data synchronization is an abnormal operation and may last for a period of time. For example, when node A exits the production environment, the block data is written to production block m, and when node B exits the production environment, the block data is written to production block m+1. If data synchronization is not completed after joining the test environment, the test case execution starts, node A executes the test case, and writes test block m+1, so that the data of m+1 blocks of nodes A and B are inconsistent. Therefore, after joining the test area, PMU checks the synchronization execution, keeps the data of nodes A and B synchronized to production block m+1, and writes test data starting from m+2.

[0525] d) Node information updates include: node status, ownership, and installed smart contract information and versions.

[0526] e) The node is switched to the blockchain network by stopping or starting the node (as above, instructing the node to exit the production channel or join the test channel). The parameters usually included in starting a node include: the node's certificate directory, the node's blockchain storage directory, and the database configuration parameters for the node's storage status data. The configuration parameters of the production or test blockchain network are installed and configured on the node to achieve the purpose of joining the production or test blockchain network.

[0527] f) Replication of blockchain ledger data. The underlying storage of block data is a file system, and the built-in database stores the blockchain index, and the block file number and its offset can be located by the block number or transaction ID. Therefore, there are two ways to replicate the chain block data in the production area: physical replication (specifically, replication of data) and logical replication (specifically, replication of links). Specifically:

[0528] Method 1) Physical copying: The blockchain built-in index database locates the transaction ID or chain block number to be copied to determine the file number and offset. The specified file number and the data and index data before the deviation are copied to the test area, and the directory data of the index data is changed. For example, the original index record:

[0529] Block number 00222–> / prod / blkfile032 offset:1000;

[0530] Change to:

[0531] Block number 00222–> / test / blkfile032 offset:1000.

[0532] Method 2) Logical replication, only copy the index data to the test area. Subsequent test data can be placed in the / test / directory, and the data copied from the production area remains in the production area. In this way, the blockchain index includes two prefixes: prod indicates production area data, and test indicates test area data.

[0533] Example 5, test process, such as Fig.13 As shown:

[0534] The organization administrator requests the PMU to specify the channel test, and the PMU obtains the test case from the SCR (corresponding to the above-mentioned determination of the contract parameter information according to the test instruction upon receipt of the test instruction; and obtaining the corresponding test case from the contract registry according to the contract parameter information); the PMU instructs the node of the affiliated test channel to execute test case 1 (corresponding to the above-mentioned acquisition of test data according to the test case and the signature data of the PMU; and sending the test data to the node whose node type is the test type); the node interacts with the blockchain of the test type (i.e., the blockchain test in the figure) for network consensus and transaction on-chain to complete the test of case 1; subsequently, the PMU can instruct the node of the affiliated test channel to execute test case n, which is similar to test case 1 and will not be repeated here. The above can also be understood as: the organization administrator selects the test channel through the PMU, the PMU provides the smart contract number and name on the test channel, the PMU requests the SCR through the smart contract number, and the SCR returns the test case of the formulated smart contract to the PMU; the PMU sends the test cases one by one to the affiliated channel Peer to execute the cases.

[0535] Specifically, the technical implementation requirements are as follows:

[0536] a) The node can verify the signature data of the smart contract, and if the verification is correct, execute the subsequent test cases (corresponding to the above-mentioned node receiving the test data sent by the PMU; verifying the signature data in the test data; and executing the test cases in the test data if the verification is successful);

[0537] b) The execution of the test case includes a technical process of three stages: proposal, sorting, packaging transactions into blocks, and verification and submission. The specific implementation can be done using existing methods and will not be described in detail here.

[0538] Example 6: Smart contract installation and upgrade process, such as Fig.14 As shown:

[0539] The organization administrator requests the PMU to install or upgrade the smart contract, and the PMU obtains the smart contract from the SCR accordingly, and then instructs the corresponding node to upgrade the smart contract (corresponding to the above-mentioned case where the processing instruction for installing and / or updating the contract is received, the contract program file is obtained from the contract registry according to the processing instruction; and the contract processing instruction information is sent to the fourth node according to the contract program file); after receiving the instruction, the node installs or upgrades the smart contract accordingly (corresponding to the above-mentioned receiving the contract processing instruction information sent by the PMU; verifying the signature data in the contract processing instruction information; if the verification is passed, the contract is installed and / or updated according to the contract program file in the contract processing instruction information), and then the node executes the channel smart contract instance update to the blockchain, and then responds to the PMU (corresponding to the above-mentioned feedback of processing response information to the PMU according to the processing result); the PMU updates the node information to the PSR accordingly (corresponding to the above-mentioned updating of the node information of the fourth node after receiving the processing response information fed back by the fourth node according to the contract processing instruction information), and then notifies the organization administrator that the process is completed (corresponding to the above-mentioned display of the processing response information).

[0540] The above can also be understood as: the organization administrator requests to install or upgrade the smart contract in PMU, selects the smart contract to be installed, and requests SCR to return the program file of the smart contract according to the smart contract number. PMU installs or upgrades the program file of the smart contract to Peer, and Peer performs subsequent operations accordingly (see above).

[0541] The node information to be updated may include the channel and contract to which the node belongs.

[0542] Specifically, the technical implementation requirements are as follows:

[0543] a) The node can verify the signature data of the smart contract. If the verification is correct, the subsequent smart contract installation or upgrade process will be executed;

[0544] b) The installation or upgrade of smart contracts can be implemented using existing methods, which will not be described in detail here.

[0545] The following is an example of the application scenario process of this solution.

[0546] The processes involved in the above examples can be combined and used in various scenarios. For example, the following process can be used in the new version test launch scenario:

[0547] 1. Execute the process involved in Example 1: smart contract registration process, submit a new version of the smart contract and test set.

[0548] 2. Execute the process involved in Example 4: Create a new test channel for some nodes from the production area. You can use the data in the production environment to avoid the preparation of a large amount of test data and test data. If the node resources are insufficient, you can execute the process involved in Example 2 and Example 3 to add new nodes to join the test network.

[0549] 3. Execute the process involved in Example 5 to test the new version of the smart contract. During the testing process, each time the smart contract is updated, the processes involved in Examples 1 and 6 need to be executed.

[0550] 4. After the test is completed, execute the process involved in Example 6 to upgrade the smart contract of the node in the production environment.

[0551] 5. Execute the process involved in Example 4, add the test node to the production area, and restore the block data synchronization from the last time it exited the production area.

[0552] Other typical application scenarios:

[0553] 1. Performance testing: By adjusting the ratio of test nodes to production nodes, increasing the number of test nodes during idle time, and using production data for performance testing, this saves investment in server resources and reduces the cost and time of building test data and test cases.

[0554] 2. Before the new smart contract is officially launched, multiple organizers configure all nodes as test nodes and conduct full pre-launch testing with the joint participation of multiple parties. After the test is completed, the smart contract is launched by adjusting the ratio of production nodes and test nodes.

[0555] As can be seen from the above, this solution proposes the functions and architecture of the node management unit PMU added to the blockchain network, as well as the technical methods for PMU to manage and implement the original peer nodes of the blockchain; thereby achieving:

[0556] 1. It is conducive to the open testing and supervision of blockchain smart contracts. Multiple organizations join the unified blockchain network for testing, which increases the openness and scenario diversity of the test, and is more in line with the real scene; it avoids the incomplete and insufficient testing in the closed environment of the organization. At the same time, due to the irrevocability of the blockchain, "code and law" is proposed. The correctness of the code depends on the programmer. A public and open test network is conducive to various personnel to verify the correctness of the smart contract.

[0557] 2. The production environment and the test environment share the same smart contracts, applications, and policies; avoiding test deviations caused by inconsistencies between the test environment and the production environment.

[0558] 3. Seamless connection for new smart contract testing and release, adjustable node ratio, and smooth transition from test network to production network.

[0559] The embodiment of the present invention further provides an information processing device, which is applied to a node management unit PMU, such as Fig.15 As shown, the device comprises:

[0560] A first sending module 151 is configured to send second indication information to the first node according to the first indication information when receiving the first indication information;

[0561] A first receiving module 152, configured to receive node change result information fed back by the first node according to the second indication information;

[0562] The first indication information is used to instruct the first node to change the node type;
