Fig. 3 is a schematic diagram of a chain code deployment system according to an embodiment of the present application. Referring to fig. 3, the chain code deployment system includes: a plurality of devices 301 and a blockchain system 302.

The target device 301 is included in the plurality of devices 301, and the blockchain system 302 may be the blockchain system 100 described above in the embodiments of fig. 1-2.

For any one device 301 of the plurality of devices 301, the one device 301 may be a general purpose computer device or a special purpose computer device. In a specific implementation, the device 301 may be a desktop, a laptop, a web server, a palmtop, a mobile phone, a tablet computer, a wireless terminal device, a communication device, or an embedded device, and the embodiment of the present application does not limit the type of the device 301.

In another possible approach, the device 301 is a device that is not capable of communicating directly with the blockchain system 302, e.g., the device 301 may be a terminal device, etc. In this way, referring to fig. 4, the chain code deployment system may further include a service platform 303. The service platform 303 is a platform that can access the blockchain system 302, for example, the service platform 303 may be a BaaS platform. The service platform 303 may communicate with the device 301 through a wired network or a wireless network, and the service platform 303 may also communicate with the blockchain system 302 through a wired network or a wireless network. In this manner, this device 301 can communicate with the blockchain system 302 through the service platform 303.

The structure of the blockchain system 302 is described below.

Referring to fig. 5, the blockchain system 302 may include one or more organizations 500 and one or more channels 502, and the blockchain system 302 is illustrated in fig. 5 as including three organizations 500 and one channel 502. Each organization 500 includes one or more compute nodes (i.e., peer nodes) 501, one or more compute nodes 501 in each organization may join a channel 502, and each channel 502 also has a sort node (i.e., Orderer node) 503.

The same node may join one or more channels 502 and maintain an accounting book for each channel 502.

The multiple devices 301 and the blockchain system 302 may implement a chain code deployment method described in the embodiment of fig. 6 below to implement the deployment of the chain code.

The chain code deployment method provided in the embodiments of the present application is explained in detail below.

Fig. 6 is a flowchart of a chain code deployment method provided in an embodiment of the present application. Referring to fig. 6, the method includes the following steps.

It is noted that in the embodiment of the present application, each device in the plurality of devices is logged with a user identifier, and each user identifier is associated with an organization in the blockchain system. Each device corresponds to an organization in the blockchain system, and the organization corresponding to each device is an organization associated with the logged-in user identifier in the blockchain system.

The user identifier is used to identify the user, and for example, the user identifier may be a user name, a user certificate number, a user account number, and the like of the user, which is not limited in this embodiment of the application. The association relationship between the user identifier and the organization may be stored in the service platform, or may be stored in the blockchain system, which is not limited in this embodiment of the present application.

Step 601: the target device acquires the chain code information.

The target device is logged in with a target user identifier. The target user identifier is used to identify the target user, for example, the target user identifier may be a user name, a user certificate number, a user account number, and the like of the target user, which is not limited in this embodiment of the application.

A target user identification is associated with one or more organizations in the blockchain system, the target user identification having administrative rights for the one or more organizations, including but not limited to having rights to deploy chain codes in the one or more organizations. The organization associated with the target user identifier may also be referred to as an organization corresponding to the target device logged with the target user identifier.

The chain code information may be information related to a chain code. For example, the chain code information may include the name of the chain code, a profile, a version number, a source code, an endorsement policy, etc. The chain code may be an intelligent contract, such as a deposit and license contract.

The link code information acquired by the target device may be input to the target device by the target user, and may also be acquired by the target device in other manners, which is not limited in this embodiment of the present application.

For example, the target device may log in the service platform by using the target user identifier, at this time, the front end page of the service platform is displayed on the target device, the target user may input the chain code information in the front end page, and the target device may acquire the chain code information input by the target user on the front end page.

Step 602: and the target equipment sends a chain code packaging request carrying the chain code information to the block chain system.

The link code packaging request is used for requesting a target organization corresponding to the target device (namely, a target organization associated with the target user identifier) to package the link code. Optionally, the chain code packaging request may carry a target organization identifier, where the target organization identifier is used to identify the target organization, for example, the target organization identifier may be a name of the target organization.

In one possible approach, the target device may send the chain code packing request directly to the blockchain system. In another possible manner, the target device may first send the chain code packaging request to the service platform, and then the service platform sends the chain code packaging request to the blockchain system.

In some embodiments, if a target user identification is associated with only one organization in the blockchain system, then this organization may be directly taken as the target organization. In this case, the target device may directly generate a chain code packaging request carrying the identifier of the organization (i.e. the target organization identifier) and the chain code information.

If the target user identification is associated with multiple organizations in the blockchain system, one of the multiple organizations may be selected as the target organization. Specifically, the target device may display a plurality of tissue identifications; when the target device detects a selection operation for one of the plurality of tissue identifiers, the selected one tissue identifier is taken as a target tissue identifier. In this case, the target device may generate a chain code packaging request carrying the target organization identifier and the chain code information, where the chain code installation request is used to request the target organization identified by the target organization identifier to package the chain code.

The plurality of organization identities includes an identity of each of a plurality of organizations associated with the target user identity. Each organization id is used to identify an organization, which may be the name of the organization, etc.

The selecting operation is to select one tissue identity from the plurality of tissue identities. The selection operation may be triggered by a target user, for example, the selection operation may be a click operation, a slide operation, a voice operation, a gesture operation, a motion sensing operation, and the like, which is not limited in this embodiment of the present application.

Illustratively, the target device may log into the service platform using the target user identification. The service platform may obtain an identifier of each of a plurality of organizations associated with the target user identifier, that is, obtain a plurality of organization identifiers, according to the association relationship between the user identifier and the organizations, and then send the plurality of organization identifiers to the target device. After receiving the plurality of organization identifiers, the target device may display the plurality of organization identifiers on a front-end page of the service platform. Then, the target user can select one organization identifier from the plurality of organization identifiers displayed on the front page of the service platform to specify an organization that needs to package the chain code.

Step 603: and after receiving the chain code packaging request, the block chain system generates a chain code package at the computing node of the target organization according to the chain code information.

The chain code needs to be packaged into a deployable structure before installation, and optionally, can be packaged into a file in tar format, that is, a chain code package.

After receiving the chain code packaging request, the block chain system can send the chain code information carried by the chain code packaging request to the computing node of the target organization, and the computing node of the target organization generates a chain code packet according to the chain code information.

The operation of generating the chain code packet by the computing node of the target organization according to the chain code information is similar to the operation of generating the chain code packet by a certain node according to the chain code information in the related art, which is not described in detail in the embodiment of the present application. For example, a computing node of the target organization may obtain a chain code packet using a peer command based on the chain code information.

Step 604: the block chain system sends the chain code packet to the target device.

After receiving the chain code packet, the target device may obtain a chain code deployment strategy corresponding to the target channel. The target channel is the channel that needs to deploy the chain code. The chain code deployment policy is used to indicate an organization that requires chain code approval at the time of chain code deployment, wherein chain code approval is an agreement to deploy the chain code. When channels needing to deploy chain codes are different, corresponding chain code deployment strategies can be different.

The target device may locally store the chain code deployment policy corresponding to each of the one or more channels, and then obtain the chain code deployment policy corresponding to the target channel therefrom. Or, the target device may obtain a chain code deployment policy corresponding to the target channel from the service platform or the blockchain system.

Optionally, the chain code deployment policy may be used to indicate any one of: deploying chain codes in the target channel and requiring all organizations to join the target channel to approve; deploying the chain code in the target channel and requiring any organization to join the target channel for approval; deploying chain codes on a target channel requires more than half of all organizations joining the target channel to approve.

In this case, after receiving the chain code packet, the destination device needs to send the chain code packet to a device corresponding to another organization in order to obtain approval from the other organization.

In one possible approach, after receiving the chain code packet, the target device sends the chain code packet to other devices according to an organization indicated by the chain code deployment policy.

In this way, the target device may first determine the user identifier associated with the organization indicated by the chain code deployment policy, and then send the chain code packet to the device logged in with the determined user identifier.

In another possible manner, after the target device receives the chain code packet, the target user knows the chain code packet, and then may notify other users of the chain code packet, and the other users may input the chain code packet to devices logged in with their respective user identifiers.

Step 605: each device in the plurality of devices sends a chain code installation request carrying the chain code packet to the blockchain system.

The plurality of devices includes a target device. Each device is logged with a user identification, each user identification associated with an organization in the blockchain system. The chain code installation request sent by each device is used for requesting an organization corresponding to each device (namely, an organization associated with the user identifier logged in by each device) to install the chain code. Optionally, the chain code installation request may further carry a target channel identifier, where the target channel identifier is used to identify a target channel in which the chain code needs to be deployed, and for example, the target channel identifier may be a name of the target channel.

It should be noted that, for any one of the multiple devices, if the user identifier logged in by the device is only associated with one organization in the blockchain system, the device may directly send a chain code installation request carrying the identifier of the organization and the chain code packet to the blockchain system. The chain code installation request is used for requesting the organization installation chain code identified by the carried organization identification.

If the user identifier of the device log-in is associated with a plurality of organizations in the blockchain system, one of the organizations can be selected from the plurality of organizations. Specifically, the device may display a plurality of organization identifiers, where the plurality of organization identifiers include an identifier of each of a plurality of organizations associated with the user identifier logged in by the device; the device may generate a chain code installation request carrying the selected organization identifier and the chain code packet when detecting a selection operation for one of the plurality of organization identifiers. The chain code installation request is used for requesting the organization installation chain code identified by the carried organization identification.

Illustratively, this device may log into the service platform using the user identification. The service platform may obtain an identifier of each of a plurality of organizations associated with the user identifier logged in by the device, that is, obtain a plurality of organization identifiers, according to the association relationship between the user identifier and the organizations, and then send the plurality of organization identifiers to the device. After receiving the plurality of organization identifiers, the device may display the plurality of organization identifiers on a front-end page of the service platform. Thereafter, the user may select one of the organization identifiers displayed on the front page of the service platform to designate an organization to which the chain code needs to be installed. The user may then enter the chain code package in the front page of the service platform and click the install button. The device may generate and send a chain code installation request carrying the selected organization identifier and the chain code packet to the service platform. After receiving the chain code installation request, the service platform may send the chain code installation request to the blockchain system.

Step 606: and when the block chain system receives a chain code installation request sent by one device, installing a chain code at a computing node of a corresponding organization according to the chain code packet carried by the received chain code installation request.

After receiving a chain code installation request sent by a device, the blockchain system may send the chain code installation request to a computing node of an organization corresponding to the device (i.e., an organization associated with a user identifier logged in by the device, i.e., an organization identified by an organization identifier carried in the chain code installation request), and the computing node installs a chain code according to the chain code packet.

The operation of the computing node for installing the chain code according to the chain code package is similar to the operation of a certain computing node for installing the chain code according to the chain code package in the related art, which is not described in detail in the embodiment of the present application.

The chain code can be approved by the computing node in the process of installing the chain code according to the chain code package, and the chain code can be successfully installed only after the chain code is approved. In other words, if the computing node successfully installs the link code according to the link code package, it indicates that the computing node passed the link code approval, i.e., that the organization to which the computing node belongs approves the link code.

And the computing node can send a confirmation message carrying the chain code packet identifier to the sequencing node in the block chain system after the chain code is successfully installed according to the chain code packet. Specifically, the computing node may send a confirmation message carrying the link code packet identifier to the sorting node of the target channel identified by the target channel identifier carried in the link code installation request. The chain code packet identifier is used to identify the chain code packet, for example, the chain code packet identifier may be a name of the chain code packet. The confirmation message indicates that the organization to which the compute node belongs has recognized the chain code.

In this case, after receiving the confirmation message carrying the link code packet identifier sent by each computing node, the sequencing node may know that each computing node has successfully installed the link code, and thus, know that the organization to which each computing node belongs has approved the link code. That is, the sequencing node may determine the organization that has acknowledged the chain code according to all the received acknowledgement messages carrying the identification of the chain code packet.

Step 607: the target device sends a chain code instantiation request to the blockchain system.

The chain code instantiation request is used for requesting to instantiate the chain code, and the chain code instantiation request can carry chain code initialization parameters. Optionally, the chain code instantiation request is used to request to instantiate the chain code in the target channel, and at this time, the chain code instantiation request may carry the target channel identifier.

Illustratively, the target device may log into the service platform using the target user identification. At this time, the target device displays a front-end page of the service platform, and the target user can input chain code initialization parameters and click an instantiation button on the front-end page of the service platform. The target device may generate a chain code instantiation request carrying the chain code initialization parameter and send the chain code instantiation request to the service platform. The business platform can send the chain code instantiation request to the blockchain system.

Step 608: after the block chain system receives the chain code instantiation request, if the chain code is determined to meet the chain code deployment strategy according to the organization to which the computing node which has successfully installed the chain code belongs, the chain code is instantiated.

Specifically, the sequencing node may determine, according to all the received acknowledgement messages carrying the identifier of the chain code packet, an organization that has acknowledged the chain code, and instantiate the chain code to complete the deployment of the chain code if the organization that has acknowledged the chain code is consistent with the organization indicated by the chain code deployment policy. The operation of the sequencing node for instantiating the chain code is similar to the operation of a certain node for instantiating a certain chain code in the related art, which is not described in detail in the embodiments of the present application.

For example, the chain deployment policy is used to indicate that deployment of the chain at the target channel requires approval by all organizations that join the target channel. The sequencing node may instantiate the chain code if all organizations joining the target channel approve the chain code, at which point deployment of the chain code on the target channel is complete.

For another example, the chain deployment policy is used to indicate that deployment of the chain at the target channel requires approval by any organization that joins the target channel. The sequencing node may instantiate the chain code if any organization joining the target channel approves the chain code, at which point deployment of the chain code on the target channel is complete.

As another example, the chain deployment policy is used to indicate more than half of all organizations that the target channel deployment chain needs to join the target channel approve. The sequencing node may instantiate the chain code if most organizations joining the target channel have recognized the chain code, at which point deployment of the chain code on the target channel is complete.

In an embodiment of the present application, a plurality of devices logged in with a user identifier associated with each of a plurality of organizations send a chain code installation request to a blockchain system. And when the block chain system receives a chain code installation request sent by one device, installing a chain code at a computing node of a corresponding organization according to a chain code packet carried by the received chain code installation request. Thus, when the chain code is deployed, each organization in a plurality of organizations realizes the approval of the chain code when the chain code is installed, so that the deployment authority of the chain code is dispersed to the related plurality of organizations, and the peer-to-peer of the organization authority is realized when the chain code is deployed. And then, after the block chain system receives the chain code instantiation request, if the chain code is determined to meet the chain code deployment strategy according to the organization to which the computing node successfully installed the chain code belongs, instantiating the chain code, and completing the deployment of the chain code. Therefore, the installation, approval and instantiation operations of the chain code are separated, and the flexibility of the system is improved.
