And is not particularly limited herein.

It should be noted that the method for accessing the blockchain network provided by the embodiment of the present disclosure is generally performed by the management server 107, and accordingly, the device for accessing the blockchain network is generally disposed in the management server 107.

It should be understood that the number of block chain extended networks, proxy servers, user terminals, etc. in fig. 1 is merely illustrative. There may be any number of blockchain extended networks, proxy servers, user terminals, as desired for implementation.

With continued reference to fig. 2, a flow 200 of one embodiment of a method of accessing a blockchain network is shown in accordance with the present disclosure. The method for accessing the block chain network comprises the following steps:

in step 201, a blockchain network access request is received.

In this embodiment, the blockchain network access request may be used to request access to the blockchain network to implement various operations on the blockchain network. For example, the access request may be for requesting creation of a new ledger or smart contract, initiating a transaction, and so forth.

A blockchain network may refer to a network built from several network nodes based on blockchain techniques. Specifically, the building of the blockchain network can be realized by utilizing various blockchain service platforms. For example, a blockchain network is built based on baas (blockchain as a service).

An executing agent (e.g., management server 107 shown in fig. 1, etc.) of the method of accessing a blockchain network may receive a blockchain network access request. The blockchain network access request can be initiated by a user of the blockchain network according to actual needs.

For example, a user may use a user terminal used by the user to access a Web application or a client application provided by the blockchain service platform to send a blockchain network access request to a backend server of the blockchain service platform (e.g., the control server 108 shown in fig. 1), and the backend server of the blockchain service platform may send the blockchain network access request to the execution subject. For another example, after accessing the blockchain service platform, the user may initiate a blockchain network access request through an interface provided by the blockchain service platform.

Step 202, selecting a blockchain network matched with the access request from a preset blockchain network group as a target blockchain network.

In this embodiment, the blockchain network group may be composed of a blockchain main network and at least one blockchain expansion network. The blockchain master network and the blockchain expansion network may be various types of blockchain networks. The blockchain expansion network can be obtained by expanding according to expansion requirements on the basis of a blockchain main network, so that a better service is provided by utilizing a blockchain network group obtained by expansion. Each blockchain network in the blockchain network group may correspond to a different proxy server. The proxy server may act as a communication bridge between the corresponding blockchain network and the outside world.

The blockchain network that matches the access request may refer to a blockchain network that is capable of responding to the access request. Generally, each blockchain network in the blockchain network group is independent of each other. The ledger, the intelligent contract, the transaction data and the like stored in each blockchain network may be the same or different. Thus, only a portion of the blockchain networks in the set of blockchain networks may be able to respond to the access request. For example, if the access request is for operating ledger "a," then the blockchain network in the blockchain network group having ledger "a" may be considered the blockchain network matching the access request.

The execution agent may use various methods to select a blockchain network from the set of blockchain networks that matches the access request. For example, the blockchain networks may be sequentially selected from the blockchain network group according to a preset sequence, and then it is determined whether the selected blockchain network can respond to the access request, and if it is determined that the selected blockchain network can respond to the access request, the selected blockchain network may be used as the target blockchain network. In particular, various methods may be employed to determine whether the selected blockchain network can respond to the access request. For example, a confirmation request may be sent to the proxy server corresponding to the selected blockchain network, and then the proxy server corresponding to the selected blockchain network determines whether the blockchain network can respond to the access request, and returns a confirmation result to the execution main body.

Step 203, sending the access request to a proxy server corresponding to the target block chain network.

In this embodiment, the execution subject may forward the access request to a proxy server corresponding to the target blockchain network, so that the proxy server may control the corresponding blockchain network to respond to the received access request, thereby obtaining a response result.

In some optional implementations of this embodiment, the preset blockchain network group may be generated in advance by: and receiving a block chain network creation request, and creating a corresponding block chain main network and at least one block chain expansion network as a block chain network group according to the creation request. Wherein the creation request may be for requesting creation of a blockchain master network and at least one blockchain expansion network. In general, the creation of a blockchain network group may be implemented by a blockchain service platform.

Specifically, various parameters may be included in the creation request to describe the desired constructed blockchain network group according to the actual application requirements. For example, parameters include, but are not limited to: the number of blockchain expansion networks, the name of the blockchain master network, the name of the blockchain expansion network, the lower-level underlying protocol used by the blockchain network, the current version, the consensus mechanism used by the blockchain network, etc. At this time, the corresponding blockchain main network and at least one blockchain expansion network can be created as the blockchain network group according to the parameters in the creation request.

In this case, it can be realized that the blockchain master network can be expanded according to actual application requirements before the blockchain master network is established.

In some optional implementations of this embodiment, the preset blockchain network group may be updated by: and receiving a block chain network expansion request, and creating a block chain expansion network corresponding to the main block chain network in the block chain network group according to the expansion request. The expansion request may be used to request to create a blockchain expansion network corresponding to the blockchain master network, so as to implement expansion of the blockchain network.

Specifically, various parameters may be included in the extension request to describe the block chain extension network that is expected to be newly added according to the actual application requirements. For example, parameters include, but are not limited to: the identification of the main network of the blockchain, the name of the newly added blockchain expansion network, a consensus mechanism used by the blockchain network, and the like. At this time, a blockchain extension network can be created according to the parameters in the extension request and added to the blockchain network group.

In this case, it can be realized that after the component block chain master network, the block chain master network can be dynamically expanded according to the actual application requirement.

In addition, the operations such as updating or deleting the blockchain extension network in the blockchain network group can be performed according to the actual application requirements, so as to further improve the flexibility of the blockchain network extension.

Optionally, the parameters in the above-mentioned blockchain network creation request may include network parameters of each blockchain network in the created blockchain network group. Network parameters include, but are not limited to, at least one of: storage location, number of network nodes.

Wherein the storage location may be used to indicate a storage location of data in the blockchain network. For example, the storage location may be a designated hard disk or the like. The number of network nodes may be the number of network nodes comprised by the blockchain network. The network parameters of each blockchain network in the blockchain network group may be the same or different.

Correspondingly, the parameters in the block chain network extension request may include network parameters of the created block chain extension network. Network parameters include, but are not limited to, at least one of: storage location, number of network nodes.

Wherein the storage location may be used to indicate a storage location of data in the created blockchain extended network. For example, the storage location may be a designated hard disk or the like. The number of network nodes may be the number of network nodes comprised by the created blockchain extension network. The network parameters of the created blockchain extended network and the network parameters of each blockchain network in the current blockchain network group can be the same or different.

In the expansion process of the blockchain network, various network parameters of the blockchain network, such as clustering, storage and the like, can be dynamically specified according to requirements, so that the convenience and flexibility of the blockchain network expansion are further improved.

Optionally, after each network node in the blockchain network is started, identification information such as the service address of the network node and the corresponding proxy server may be sent to a back-end server of the blockchain service platform, and then the back-end server forwards the information to the execution main body, so that the execution main body may record information such as the service address of each proxy server, thereby facilitating subsequent distribution processing of the access request.

Alternatively, each blockchain network in the blockchain network group may be deployed in a different cluster, respectively, so as to more effectively manage and control each blockchain network. For example, a kubernets service may be utilized to create a blockchain master network and a blockchain expansion network, and deploy the created blockchain master network and blockchain expansion network in different clusters.

When using the kubernets service, resources and the like required by various components or services and the like may also be deployed by using the kubernets service, for example, Pod services and the like of each component are started, and specifically, one Pod service may be started for each network node, so as to facilitate management and maintenance of the blockchain network.

In this case, the network parameters in the above block chain network creation request may further include the cluster to which the network parameters belong. At this time, the cluster may indicate a cluster to which each blockchain network in the created blockchain network group respectively belongs. Correspondingly, the network parameter in the block chain network extension request may include the cluster to which the network parameter belongs. At this time, the cluster may indicate a cluster to which the created blockchain extension network belongs.

And each block chain network is deployed by using the cluster service, so that the management, deployment, maintenance and the like of each block chain network are facilitated.

In some optional implementation manners of this embodiment, when the number of the blockchain networks matched with the access request in the blockchain network group is multiple, various methods may be flexibly adopted according to an application scenario to select one blockchain network from the multiple matched blockchain networks as a target blockchain network. For example, one blockchain network may be randomly selected from the matched plurality of blockchain networks as the target blockchain network. For another example, one blockchain network may be randomly selected from the multiple matched blockchain networks as a target blockchain network by using a hash modeling method according to a transaction hash carried by the access request, so as to implement efficient access request distribution.

In some optional implementations of the embodiment, the network parameters included in the blockchain network creation request and the blockchain network extension request may be obtained based on various visualization techniques. For example, a page for inputting network parameters may be presented on a screen using various visualization techniques, so that network parameters may be obtained based on the page for user convenience.

It should be noted that, if the access request specifies a target block chain network (e.g., includes an identifier of a proxy server), the access request may be directly sent to the proxy server specified by the access request, so as to improve the access processing efficiency.

By way of example, referring to fig. 3a and 3b, fig. 3a shows a schematic diagram of a visualization interface corresponding to a blockchain network creation request, and fig. 3b shows a schematic diagram of a visualization interface corresponding to a blockchain network extension request. As shown in fig. 3a, the visual interface may be presented at the user terminal initiating the blockchain network creation request, and the user may fill out the network name "net 01", the underlying protocol "X" used, the current version "1.5.0", and the consensus mechanism "Raft" used of the blockchain primary network desired to be created according to actual requirements. In addition, a multi-selection button for supporting the browser is displayed in the visual interface. If "yes" is selected, indicating that a browser is supported, the user may view various information (e.g., attributes of various transactions, number of parties, etc.) of the blockchain primary network through the browser. Correspondingly, if "no" is selected, which means that the browser is not supported, the user cannot view various information of the blockchain main network through the browser.

In addition, a multi-selection button for judging whether to create a multi-network is displayed in the visual interface. If "yes" is selected, it means that the blockchain extension network is added. If 'no', it means that no blockchain extension network is added.

When the add blockchain extended network is selected, the added blockchain extended network may be continuously added through the "+" button. For example, add blockchain extension network "net 01-1" is selected and indicates that blockchain extension network "net 01-1" is deployed in cluster "cluster 1," data is stored using "storage 1" and the number of network nodes is "1". Then, add blockchain extension network "net 01-2" is selected, and blockchain extension network "net 01-2" is instructed to be deployed in cluster "cluster 2", store data using "storage 2" and the number of network nodes is "2". After entering the parameters, the user can click on the "create network" button to submit the parameters, which facilitates the creation of the corresponding blockchain main network and blockchain expansion network.

As shown in fig. 3b, the visual interface may be presented at the user terminal initiating the blockchain network extension request, and information (such as network name, cluster where the blockchain network is located, storage, node number, and the like) of each blockchain extension network that has been currently extended may be presented in the visual interface. The user can click on the "expand" button according to actual needs to add a new blockchain expanded network. For example, new blockchain extension networks "net 01-3" and "net 01-4" may be added, while the cluster, storage, and number of nodes in which each added blockchain extension network resides may be specified. After inputting each parameter, the user can click a 'submit' button to submit each parameter, so as to add a corresponding blockchain expansion network.

In a blockchain network deployed by BaaS and the like in the prior art, only one proxy server is usually used as an entrance of all access requests. In this case, when a large number of concurrent requests are received, the processing efficiency is low, and when the proxy server is abnormal, the normal operation of the whole blockchain network and the access to the blockchain network are directly affected. Moreover, due to the influence of a common recognition mechanism (for example, a Raft mechanism only allows one node to process an access request), when a large flow of requests is encountered, problems such as long response time, low throughput, low QPS (query rate Per Second) and the like easily occur.

The method provided by the above embodiment of the present disclosure disperses the blockchain main network and each blockchain expansion network, and each blockchain main network or each blockchain expansion network has a corresponding proxy server, and receives the access request by the management server and forwards the access request to the corresponding proxy server, so as to disperse the network load, and not only facilitate dynamic expansion of the blockchain main network at any time, but also improve the maximum access request amount that the blockchain network can bear and the processing efficiency of the access request, thereby alleviating the problems in the prior art.

With further reference to fig. 4, a flow 400 of yet another embodiment of a method of accessing a blockchain network is shown. The process 400 of the method for accessing a blockchain network includes the following steps:

in step 401, a blockchain network access request is received.

In this embodiment, the access request may include an operation object identifier. Wherein the operand identification may be used to identify the operand that the access request is expected to handle. The operation object includes, but is not limited to, at least one of the following: account book, intelligent contract. The operation object identifier may adopt various representation methods according to actual application scenarios.

Step 402, selecting the block chain network with the operation object indicated by the operation object identification included in the access request from the block chain network group as a target block chain network.

In this embodiment, the blockchain network in which the operation object indicated by the operation object identifier included in the access request is recorded may be determined as the target blockchain network. In particular, various methods may be employed to determine the target blockchain network.

For example, the execution body may store in advance the operation objects recorded in each blockchain network in the blockchain network group. At this time, the blockchain network in which the operation object indicated by the operation object identifier included in the access request is recorded may be determined by querying.

Since the blockchain networks correspond to the proxy servers one to one, the execution subject may record the identifiers (such as service addresses, etc.) of the proxy servers corresponding to the blockchain networks, so as to forward the access request to the proxy servers. In this case, the identifier of the proxy server may also be regarded as the identifier of the corresponding blockchain network.

Step 403, sending the access request to a proxy server corresponding to the target block chain network.

As an example, for an access request indicating creation of an ledger and/or deployment of an intelligent contract, a proxy server corresponding to the ledger and/or the intelligent contract indicated by the access request may be queried, so that the access request is forwarded to the proxy server, so that the proxy server controls a corresponding blockchain network thereof to complete creation of the ledger and/or deployment of the intelligent contract.

As another example, for an access request instructing to call a specified intelligent contract to write a transaction into a specified ledger (for example, for a transaction instructing to call an intelligent contract to write "Key ═ X" into a ledger "B"), the ledger indicated by the access request and the proxy server corresponding to the intelligent contract may be determined, and if there are a plurality of proxy servers, one proxy server may be selected from the plurality of proxy servers by using a hash modeling method according to the transaction hash, and the blockchain network corresponding to the selected proxy server may be used as the target blockchain network.

As another example, for an access request indicating that a specific intelligent contract is called to query a specific account book for a transaction (for example, calling "Value" of an intelligent contract "a" to query a "Key" from an account book "B"), the account book indicated by the access request and the proxy server corresponding to the intelligent contract may be determined, if there are a plurality of proxy servers, one proxy server may be selected from the plurality of proxy servers by using a hash modeling method according to a transaction hash, and a blockchain network corresponding to the selected proxy server is used as a target blockchain network.

The execution process not specifically described in each step in this embodiment may refer to the related description in the corresponding embodiment of fig. 2, and is not described herein again.

According to the method provided by the embodiment of the disclosure, the target block chain network to which the access request indicates to access is determined according to the operation object specified by the access request, so that the access request can be accurately forwarded to the proxy server corresponding to the target block chain network, and the proxy server controls the target block chain network to respond to the access request, thereby realizing distributed processing of the access request and contributing to improvement of processing efficiency of the access request.

With further reference to fig. 5, a timing diagram 500 of one embodiment of a system of accessing a blockchain network of the present disclosure is shown. The system includes a management server (e.g., management server 107 shown in fig. 1) and at least two proxy servers (e.g.,

proxy servers

104, 105, 106 shown in fig. 1) communicatively coupled to the management server. Each proxy server may provide proxy services for a corresponding blockchain network.

In step 501, a management server receives a blockchain network access request.

In step 502, the management server selects a blockchain network matching the access request from a preset blockchain network group as a target blockchain network.

In step 503, after receiving the access, the proxy server controls the corresponding blockchain network to respond to the received access request.

Optionally, the system for accessing a blockchain network further comprises a control server. The control server may receive a blockchain network creation request. The creation request is used for requesting the creation of the blockchain main network and at least one blockchain expansion network. Then, the control server may create the corresponding blockchain main network and at least one blockchain expansion network as a blockchain network group according to the creation request.

Optionally, the control server may also receive a blockchain network extension request. The expansion request may be used to request to create a blockchain expansion network corresponding to the blockchain master network. Then, the control server may create a blockchain expansion network corresponding to the blockchain main network in the blockchain network group according to the expansion request.

Alternatively, the control server may control each blockchain network in the blockchain network group to be respectively deployed in different clusters. At this time, the network parameters of each blockchain network in the created blockchain network group may be included in the creation request. The network parameters may include at least one of: cluster, storage location, number of network nodes. Correspondingly, the extension request comprises network parameters of the created block chain extension network, and the network parameters comprise at least one of the following items: cluster, storage location, number of network nodes.

Alternatively, the control server may obtain the network parameters included in the creation request based on visualization techniques. Correspondingly, the control server may obtain the network parameters included in the extension request based on the visualization technology.

Optionally, the system for accessing the blockchain network may further include a user terminal. The user terminal may send a blockchain network access request to the control server. The control server may transmit the received access request to the management server.

Referring now to fig. 6, shown is a timing diagram 600 of yet another embodiment of the system for accessing a blockchain network of the present disclosure.

In step 601, the control server receives a blockchain network creation request sent by a user terminal.

In step 602, the control server may create a corresponding blockchain master network and at least one blockchain expansion network as a blockchain network group according to the creation request.

In step 603, the control server may receive a blockchain network access request sent by the user terminal.

In step 604, the control server may send a blockchain access request to the management server.

In step 605, the management server may select a blockchain network matching the access request from the previously created blockchain network group as a target blockchain network.

In step 606, the management server may send the blockchain access request to a proxy server corresponding to the target blockchain network.

In step 607, the proxy server may control the target blockchain network to respond to the received blockchain access request.

In step 608, the control server may receive the blockchain network extension request sent by the user terminal.

In step 609, the control server may create a corresponding blockchain extension network to join the previously created blockchain network group according to the extension request.

In some optional implementations of this embodiment, the user terminal may send a deployment request for the blockchain extended networks in the blockchain network group to the control server. The deployment request may be used to request the access right of the deployment user terminal to the block chain extended network.

At this time, the user terminal may be a participant (except for the initiator) of the constructed blockchain network group. In general, a participant may access a blockchain primary network. However, when desiring to access the blockchain extended network, the participant needs to first send a deployment request for the blockchain extended network that is desired to be accessed, so that the control server deploys the access right of the participant for the blockchain extended network, so that the participant can access the blockchain extended network. The access right of specific deployment can be flexibly set according to actual application requirements.

As an example, upon receiving a deployment request by a participant for a blockchain extension network, the blockchain extension network may be created for the participant. At this time, for data (such as an account book, an intelligent contract and the like) before the creation of the blockchain extended network, corresponding data can be created in the blockchain extended network according to requirements through the blockchain service platform.
