Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and in particular to a chain code deployment method, system, device and storage medium. Background Art

[0002] Chaincode is abbreviated as chaincode, which generally refers to the application code written by the user. Chaincode can be deployed on the nodes in the blockchain system, and the data in the distributed ledger of the blockchain system can be operated by calling the chaincode.

[0003] Currently, chaincode deployment can be performed through the BaaS (Backend as a Service) platform. Specifically, if a user wants to deploy a chaincode in a channel in the blockchain system, the user can upload the chaincode to be deployed to the BaaS platform after logging into the BaaS platform, and the BaaS platform will directly deploy the chaincode on the computing nodes of multiple organizations that have joined this channel.

[0004] However, in the above chaincode deployment method, users can deploy chaincodes on nodes in the blockchain system as long as they log in to the BaaS platform, and the chaincode deployment authority is too concentrated. Summary of the invention

[0086] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0087] It should be understood that the "plurality" mentioned in this application refers to two or more. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish the same or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0088] Before explaining the embodiments of the present application, the relevant contents of the blockchain are explained first.

[0089] Figure 1 It is a structural diagram of a blockchain system provided in an embodiment of the present application.

[0090] See also Figure 1, the blockchain system 100 refers to a system for sharing data between nodes. The blockchain system 100 may include multiple nodes 101, and the multiple nodes 101 may refer to various clients in the blockchain system 100. Each node 101 can receive input information during normal operation, and maintain the shared data in the blockchain system 100 based on the received input information. In order to ensure the information intercommunication within the blockchain system 100, there may be an information connection between each node 101 in the blockchain system 100, and information can be transmitted between the nodes 101 through the information connection. For example, when any node 101 in the blockchain system 100 receives input information, other nodes 101 in the blockchain system 100 obtain the input information according to the consensus algorithm, and store the input information as data in the shared data, so that the data stored on all nodes 101 in the blockchain system 100 are consistent.

[0091] Each node 101 in the blockchain system 100 stores an identical blockchain. Figure 2 The blockchain consists of multiple blocks. The genesis block includes a block header and a block body. The block header stores the input information characteristic value, version number, timestamp and difficulty value, and the block body stores the input information; the next block of the genesis block takes the genesis block as the parent block, and the next block also includes a block header and a block body. The block header stores the input information characteristic value of the current block, the block header characteristic value, version number, timestamp and difficulty value of the parent block, and so on, so that the block data stored in each block in the blockchain is associated with the block data stored in the parent block, ensuring the security of the input information in the block.

[0092] The blockchain system 100 has computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. The blockchain system 100 is a distributed shared account book and database, which has the characteristics of decentralization, non-tamperability, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the sharing, openness, authenticity, integrity, security and reliability of the blockchain.

[0093] The system architecture involved in the embodiments of the present application is described below.

[0094] Figure 3 is a schematic diagram of a chain code deployment system provided by an embodiment of the present application. Figure 3 , the chain code deployment system includes: multiple devices 301 and a blockchain system 302.

[0095] The multiple devices 301 include a target device 301, and the blockchain system 302 can be the above Figure 1-Figure 2 The blockchain system 100 described in the embodiment.

[0096] For any one of the multiple devices 301, the device 301 may be a general-purpose computer device or a dedicated computer device. In a specific implementation, the device 301 may be a desktop computer, a portable computer, a network server, a palm computer, 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.

[0097] In one possible manner, the device 301 is a device that can directly communicate with the blockchain system 302, such as the device 301 can be a network server, etc. In this manner, the device 301 can communicate with the blockchain system 302 via a wired network or a wireless network.

[0098] In another possible manner, the device 301 is a device that cannot communicate directly with the blockchain system 302, such as the device 301 can be a terminal device, etc. In this manner, see Figure 4 , the chain code deployment system may further include a business platform 303. The business platform 303 is a platform that can access the blockchain system 302, for example, the business platform 303 may be a BaaS platform, etc. The business platform 303 may communicate with the device 301 through a wired network or a wireless network, and the business platform 303 may also communicate with the blockchain system 302 through a wired network or a wireless network. In this way, the device 301 may communicate with the blockchain system 302 through the business platform 303.

[0099] The relevant structure of the blockchain system 302 is described below.

[0100] See also Figure 5 , the blockchain system 302 may include one or more organizations 500 and one or more channels 502, Figure 5 In the example, a blockchain system 302 includes three organizations 500 and a channel 502. Each organization 500 includes one or more computing nodes (i.e., peer nodes) 501. One or more computing nodes 501 in each organization can join a channel 502. Each channel 502 also has an ordering node (i.e., Orderer node) 503. The channels 502 in the blockchain system 302 implement private isolation between the organizations 500 in the blockchain system 302. The chain codes and transactions in each channel 502 are visible only to the nodes (including computing nodes 501 and ordering nodes 503) that have joined the channel 502. The same node can join one or more channels 502 and maintain a ledger for each channel 502.

[0101] Multiple devices 301 and blockchain system 302 can perform the following Figure 6The chain code deployment method described in the embodiment is used to implement the deployment of the chain code.

[0102] The chain code deployment method provided in the embodiment of the present application is explained in detail below.

[0103] Figure 6 This is a flowchart of a chain code deployment method provided by an embodiment of the present application. Figure 6 , the method comprises the following steps.

[0104] It is worth noting that each of the multiple devices in the embodiment of the present application is logged in with a user ID, and each user ID 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 the organization associated with the logged in user ID in the blockchain system.

[0105] The user ID is used to identify the user, such as the user ID can be the user's user name, user ID number, user account number, etc., which is not limited in the present embodiment of the application. The association between the user ID and the organization can be stored in the business platform or in the blockchain system, which is not limited in the present embodiment of the application.

[0106] Step 601: The target device obtains the chain code information.

[0107] The target device is logged in with a target user ID. The target user ID is used to identify the target user, such as the target user ID can be the user name, user ID number, user account number, etc. of the target user, which is not limited in the present embodiment of the application.

[0108] The target user ID is associated with one or more organizations in the blockchain system. The target user ID has management rights over the one or more organizations, including but not limited to the right to deploy chain codes in the one or more organizations. The organization associated with the target user ID can also be referred to as the organization corresponding to the target device logged in with the target user ID.

[0109] The chaincode information may be information related to the chaincode. For example, the chaincode information may include the name, introduction, version number, source code, endorsement policy, etc. of the chaincode. The chaincode may be a smart contract, such as a proof contract, etc.

[0110] The chain code information obtained by the target device may be input into the target device by the target user. Of course, it may also be obtained by the target device through other means, which is not limited in this embodiment of the present application.

[0111] For example, the target device can use the target user ID to log in to the business platform. At this time, the target device displays the front-end page of the business platform. The target user can enter the chain code information in the front-end page, and the target device can obtain the chain code information entered by the target user on the front-end page.

[0112] Step 602: The target device sends a chain code packaging request carrying the chain code information to the blockchain system.

[0113] The chain code packaging request is used to request the target organization corresponding to the target device (i.e., the target organization associated with the target user ID) to package the chain code. Optionally, the chain code packaging request may carry a target organization ID, which is used to identify the target organization. For example, the target organization ID may be the name of the target organization.

[0114] In one possible way, the target device can directly send the chain code packaging request to the blockchain system. In another possible way, the target device can first send the chain code packaging request to the business platform, and then the business platform sends the chain code packaging request to the blockchain system.

[0115] In some embodiments, if the target user identifier is only associated with one organization in the blockchain system, this organization can be directly used as the target organization. In this case, the target device can directly generate a chain code packaging request carrying the identifier of this organization (i.e., the target organization identifier) ​​and the chain code information.

[0116] If the target user ID is associated with multiple organizations in the blockchain system, one organization can be selected from the multiple organizations as the target organization. Specifically, the target device can display multiple organization IDs; when the target device detects a selection operation for one of the multiple organization IDs, the selected organization ID is used as the target organization ID. In this case, the target device can generate a chain code packaging request carrying the target organization ID and the chain code information, and the chain code installation request is used to request the target organization identified by the target organization ID to package the chain code.

[0117] The multiple organization identifiers include the identifier of each organization in the multiple organizations associated with the target user identifier. Each organization identifier is used to identify an organization, and the organization identifier may be the name of the organization, etc.

[0118] The selection operation is used to select an organization identifier from the multiple organization identifiers. The selection operation can be triggered by the target user, such as the selection operation can be a click operation, a slide operation, a voice operation, a gesture operation, a somatosensory operation, etc., which is not limited in the embodiment of the present application.

[0119] For example, the target device can log in to the business platform using the target user ID. The business platform can obtain the ID of each of the multiple organizations associated with the target user ID based on the association relationship between the user ID and the organization, that is, obtain multiple organization IDs, and then send the multiple organization IDs to the target device. After the target device receives the multiple organization IDs, it can display the multiple organization IDs on the front-end page of the business platform. Afterwards, the target user can select an organization ID from the multiple organization IDs displayed on the front-end page of the business platform to specify an organization that needs to package the chain code.

[0120] Step 603: After receiving the chain code packaging request, the blockchain system generates a chain code package on the computing node of the target organization according to the chain code information.

[0121] The chaincode needs to be packaged into a deployable structure before installation. Optionally, it can be packaged into a tar file, which is the chaincode package.

[0122] After receiving the chain code packaging request, the blockchain system can send the chain code information carried in the chain code packaging request to the computing node of the target organization, and the computing node of the target organization will generate a chain code package based on the chain code information.

[0123] The operation of the target organization's computing node generating a chain code package according to the chain code information is similar to the operation of a node generating a chain code package according to the chain code information in the related art, and the present application embodiment will not elaborate on this. For example, the computing node of the target organization can obtain the chain code package according to the chain code information using the peer command.

[0124] Step 604: The blockchain system sends the chain code package to the target device.

[0125] After the target device receives the chaincode package, it can obtain the chaincode deployment policy corresponding to the target channel. The target channel is the channel where the chaincode needs to be deployed. The chaincode deployment policy is used to indicate the organization that needs to approve the chaincode when the chaincode is deployed. Approving the chaincode means agreeing to deploy the chaincode. When the channels where the chaincode needs to be deployed are different, the corresponding chaincode deployment policies can be different.

[0126] The target device can locally store the chain code deployment policy corresponding to each channel in one or more channels, and then obtain the chain code deployment policy corresponding to the target channel from it. Alternatively, the target device can obtain the chain code deployment policy corresponding to the target channel from the business platform or blockchain system.

[0127] Optionally, the chaincode deployment policy can be used to indicate any of the following: deploying chaincode on the target channel requires approval from all organizations joining the target channel; deploying chaincode on the target channel requires approval from any organization joining the target channel; deploying chaincode on the target channel requires approval from more than half of all organizations joining the target channel.

[0128] In this case, after the target device receives the chain code package, it needs to send the chain code package to the corresponding devices of other organizations in order to obtain the recognition of other organizations.

[0129] In one possible approach, after receiving the chain code package, the target device sends the chain code package to other devices according to the organization indicated by the chain code deployment policy.

[0130] In this way, the target device can first determine the user ID associated with the organization indicated by the chaincode deployment policy, and then send the chaincode package to the device logged in with the determined user ID.

[0131] In another possible manner, after the target device receives the chain code package, the target user learns about the chain code package and can then inform other users of the chain code package, and other users can input the chain code package into the device logged in with their respective user IDs.

[0132] Step 605: Each of the multiple devices sends a chain code installation request carrying the chain code package to the blockchain system.

[0133] The multiple devices include the target device. Each device is logged in with a user ID, and each user ID is associated with an organization in the blockchain system. The chain code installation request sent by each device is used to request the organization corresponding to each device (i.e., the organization associated with the user ID logged in by each device) to install the chain code. Optionally, the chain code installation request may also carry a target channel ID, which is used to identify the target channel where the chain code needs to be deployed, such as the target channel ID can be the name of the target channel, etc.

[0134] It is worth noting that for any of the multiple devices, if the user ID logged in by the device is only associated with one organization in the blockchain system, the device can directly send a chaincode installation request carrying the organization's ID and the chaincode package to the blockchain system. The chaincode installation request is used to request the organization identified by the carried organization ID to install the chaincode.

[0135] If the user ID logged in by the device is associated with multiple organizations in the blockchain system, one organization can be selected from the multiple organizations. Specifically, the device can display multiple organization IDs, including the ID of each organization in the multiple organizations associated with the user ID logged in by the device; when the device detects a selection operation for one of the multiple organization IDs, it can generate a chaincode installation request carrying the selected organization ID and the chaincode package. The chaincode installation request is used to request the organization identified by the carried organization ID to install the chaincode.

[0136] For example, the device can log in to the business platform using a user ID. The business platform can obtain the ID of each of the multiple organizations associated with the user ID logged in by the device based on the association relationship between the user ID and the organization, that is, obtain multiple organization IDs, and then send the multiple organization IDs to the device. After receiving the multiple organization IDs, the device can display the multiple organization IDs on the front-end page of the business platform. After that, the user can select an organization ID from the multiple organization IDs displayed on the front-end page of the business platform to specify an organization that needs to install the chain code. After that, the user can enter the chain code package in the front-end page of the business platform and click the install button. The device can generate a chain code installation request carrying the selected organization ID and the chain code package and send it to the business platform. After receiving the chain code installation request, the business platform can send the chain code installation request to the blockchain system.

[0137] Step 606: Whenever the blockchain system receives a chain code installation request sent by a device, it installs the chain code on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request.

[0138] After the blockchain system receives a chaincode installation request sent by a device, it can send the chaincode installation request to the computing node of the organization corresponding to the device (that is, the organization associated with the user ID of the device login, that is, the organization identified by the organization ID carried by the chaincode installation request), and the computing node will install the chaincode according to the chaincode package.

[0139] The operation of the computing node installing the chain code according to the chain code package is similar to the operation of a computing node installing the chain code according to the chain code package in the related art, and this embodiment of the present application will not be elaborated in detail.

[0140] The computing node will review the chain code during the process of installing the chain code according to the chain code package, and can only successfully install the chain code after the chain code is approved. In other words, if the computing node successfully installs the chain code according to the chain code package, it means that the computing node has approved the chain code, which means that the organization to which the computing node belongs recognizes the chain code.

[0141] After the computing node successfully installs the chaincode according to the chaincode package, it can send a confirmation message carrying the chaincode package identifier to the sorting node in the blockchain system. Specifically, the computing node can send a confirmation message carrying the chaincode package identifier to the sorting node of the target channel identified by the target channel identifier carried by the chaincode installation request. The chaincode package identifier is used to identify the chaincode package, such as the chaincode package identifier can be the name of the chaincode package. The confirmation message is used to indicate that the organization to which the computing node belongs has approved the chaincode.

[0142] In this case, after receiving the confirmation message carrying the chain code package identifier sent by each computing node, the sorting node can know that each computing node has successfully installed the chain code, and also know that the organization to which each computing node belongs has approved the chain code. That is, the sorting node can determine the organization that has approved the chain code based on all the confirmation messages received that carry the chain code package identifier.

[0143] Step 607: The target device sends a chain code instantiation request to the blockchain system.

[0144] The chaincode instantiation request is used to request the instantiation of the chaincode, and the chaincode instantiation request can carry chaincode initialization parameters. Optionally, the chaincode instantiation request is used to request the instantiation of the chaincode on the target channel, and the chaincode instantiation request can carry the target channel identifier.

[0145] For example, the target device can log in to the business platform using the target user ID. At this time, the target device displays the front page of the business platform, and the target user can enter the chain code initialization parameters on the front page of the business platform and click the instantiation button. The target device can generate a chain code instantiation request carrying the chain code initialization parameters and send it to the business platform. The business platform can send the chain code instantiation request to the blockchain system.

[0146] Step 608: After the blockchain system receives the chain code instantiation request, if it is determined that the chain code meets the chain code deployment policy based on the organization to which the computing node that has successfully installed the chain code belongs, the chain code is instantiated.

[0147] Specifically, the sorting node can determine the organization that has approved the chain code based on all received confirmation messages carrying the chain code package identifier. If the organization that has approved the chain code is consistent with the organization indicated by the chain code deployment policy, the chain code is instantiated to complete the deployment of the chain code. The operation of the sorting node instantiating the chain code is similar to the operation of a node instantiating a chain code in the related art, and the embodiment of the present application will not be elaborated on this in detail.

[0148] For example, the chaincode deployment policy is used to indicate that the deployment of the chaincode on the target channel requires the approval of all organizations that join the target channel. Then the sorting node can instantiate the chaincode when all organizations that join the target channel approve the chaincode, and the deployment of the chaincode on the target channel is completed.

[0149] For another example, the chaincode deployment policy is used to indicate that the deployment of the chaincode on the target channel requires the approval of any organization that joins the target channel. Then the sorting node can instantiate the chaincode if any organization that joins the target channel approves the chaincode, and the deployment of the chaincode on the target channel is completed at this time.

[0150] For another example, the chaincode deployment policy is used to indicate that the deployment of the chaincode on the target channel requires the approval of more than half of all organizations that join the target channel. Then the sorting node can instantiate the chaincode when most of the organizations that join the target channel approve the chaincode, and the deployment of the chaincode on the target channel is completed at this time.

[0151] In an embodiment of the present application, multiple devices logged with user identifiers associated with each of the multiple organizations send chain code installation requests to the blockchain system. Each time the blockchain system receives a chain code installation request sent by a device, it installs the chain code on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request. In this way, when deploying the chain code, each of the multiple organizations recognizes the chain code when installing the chain code, thereby distributing the chain code deployment authority to the multiple related organizations, and realizing the equality of organizational authority when the chain code is deployed. Afterwards, after the blockchain system receives the chain code instantiation request, if it is determined that the chain code meets the chain code deployment policy based on the organization to which the computing node that has successfully installed the chain code belongs, the chain code is instantiated to complete the deployment of the chain code. In this way, the operations of chain code installation, approval, and instantiation are separated, which improves the flexibility of the system.

[0152] Figure 7 is a flowchart of a chain code deployment method provided by an embodiment of the present application. The method is applied to a blockchain system, which can be the above Figure 1-Figure 2 The blockchain system 100 described in the embodiment may also be Figure 3-Figure 5 The blockchain system 302 described in the embodiment. Figure 7 , the method may include the following steps:

[0153] Step 701: Receive a chain code installation request carrying a chain code package sent by each of multiple devices.

[0154] Each device corresponds to an organization in the blockchain system. Each device is logged in with a user ID. The organization corresponding to each device is the organization associated with the logged in user ID in the blockchain system.

[0156] Step 702: Every time a chain code installation request is received from a device, the chain code is installed on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request.

[0161] Step 704: If the chain code satisfies the chain code deployment policy according to the organization to which the computing node that has successfully installed the chain code belongs, the chain code is instantiated.

[0162] The chaincode deployment policy is used to indicate the organizations that need to approve the chaincode when it is deployed.

[0163] The relevant content of step 704 is already mentioned above. Figure 6 Step 608 in the embodiment is described in detail, and will not be described in detail in the embodiment of the present application.

[0164] In an embodiment of the present application, multiple devices logged with user identifiers associated with each of the multiple organizations send chain code installation requests to the blockchain system. Each time the blockchain system receives a chain code installation request sent by a device, it installs the chain code on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request. In this way, when deploying the chain code, each of the multiple organizations recognizes the chain code when installing the chain code, thereby distributing the chain code deployment authority to the multiple related organizations, and realizing the equality of organizational authority when the chain code is deployed. Afterwards, after the blockchain system receives the chain code instantiation request, if it is determined that the chain code meets the chain code deployment policy based on the organization to which the computing node that has successfully installed the chain code belongs, the chain code is instantiated to complete the deployment of the chain code. In this way, the operations of chain code installation, approval, and instantiation are separated, which improves the flexibility of the system.

[0165] Figure 8is a schematic diagram of a chain code deployment device provided in an embodiment of the present application, which can be applied to a blockchain system, and the blockchain system can be Figure 1-Figure 2 The blockchain system 100 of the embodiment may also be the Figure 3-Figure 5 Blockchain system 302 of the embodiment. Figure 8 The device includes: a receiving module 801, an installation module 802, and an instantiation module 803.

[0166] The receiving module 801 is used to receive a chain code installation request carrying a chain code package sent by each device among multiple devices, each device corresponds to an organization in the blockchain system, each device is logged in with a user ID, and the organization corresponding to each device is the organization associated with the logged in user ID in the blockchain system;

[0167] The installation module 802 is used to install the chain code on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request every time a chain code installation request sent by a device is received;

[0168] The receiving module 801 is further used to receive a chain code instantiation request, where the chain code instantiation request is used to request to instantiate a chain code;

[0169] The instantiation module 803 is used to instantiate the chain code when it is determined that the chain code meets the chain code deployment policy according to the organization to which the computing node that has successfully installed the chain code belongs. The chain code deployment policy is used to indicate the organization that needs to approve the chain code when the chain code is deployed.

[0170] Optionally, the device further includes: a generating module and a sending module;

[0178] In an embodiment of the present application, multiple devices logged with user identifiers associated with each of the multiple organizations send chain code installation requests to the blockchain system. Each time the blockchain system receives a chain code installation request sent by a device, it installs the chain code on the computing node of the corresponding organization according to the chain code package carried in the received chain code installation request. In this way, when deploying the chain code, each of the multiple organizations recognizes the chain code when installing the chain code, thereby distributing the chain code deployment authority to the multiple related organizations, and realizing the equality of organizational authority when the chain code is deployed. Afterwards, after the blockchain system receives the chain code instantiation request, if it is determined that the chain code meets the chain code deployment policy based on the organization to which the computing node that has successfully installed the chain code belongs, the chain code is instantiated to complete the deployment of the chain code.
