Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, when a node joins a blockchain, a series of operations such as node configuration, join request verification, node joining a blockchain network and the like need to be realized in steps, and although existing blockchain frameworks (for example, Fabric and the like) provide many tools and examples for the operations, still a professional is required to perform complicated and complicated configuration and operation. However, most organizations have poor understanding of the blockchain technology, which brings obstacles to users to join the blockchain ecology, and how to rapidly join the organizations into the blockchain ecology is a problem to be solved urgently. Based on this, the method and the device for joining the blockchain provided by the embodiment of the invention do not need a user to deeply understand the blockchain technology, but realize a series of operations such as node configuration, joining request verification, node joining the blockchain network and the like through the BaaS platform, thereby reducing the user operation, enabling the user to rapidly join the blockchain ecology and participate in the blockchain transaction. In addition, visualization can be realized through the BaaS platform in the process of adding the node into the block chain network, so that the running state and the operation result of the node one-key adding process can be intuitively known in real time.
For the convenience of understanding the embodiments of the present invention, a method for adding a blockchain according to the embodiments of the present invention will be described in detail below.
BaaS (Blockchain as a Service) is a Service that is used to help users create, manage, and maintain enterprise-level Blockchain networks and applications in conjunction with Blockchain technology. The main uses of BaaS are: the method can quickly establish the required block chain application environment and provide a series of operation services such as search query, transaction, data analysis and the like based on the block chain network. The embodiment of the invention realizes the purpose of rapidly adding block chain ecology by a user based on BaaS.
Fig. 1 shows a flowchart of a method for joining a blockchain according to an embodiment of the present invention. Referring to fig. 1, a method for adding a block chain provided in an embodiment of the present invention is applied to a BaaS platform, and the method includes the following steps:
s110, acquiring a first node joining request, wherein the first node joining request is used for requesting to join a node to be joined to a target block chain network;
the user to which the node to be added belongs can log in the BaaS platform through the user terminal to initiate the first node adding request by one key, the BaaS platform receives the first node adding request, and the node to be added can be the user terminal or other nodes.
The first node join request may include information of a node to be joined and a target blockchain network identification. The information of the node to be added and the target blockchain network identifier may be determined based on an operation of the user on the BaaS platform, where the operation may include selecting, filling, and the like.
The information of the node to be joined may include a joining feature, and the joining feature may include a feature attribute of the node, for example, the feature attribute of the node may include information such as a node identification, a physical address, a network address, and the like.
The target blockchain network identifier may include a name of a blockchain to be joined, an identifier of the blockchain to be joined, and the like, and the target blockchain network identifier is used to specify a target blockchain network to be joined.
For example, the first node join request may include a join instruction and a join feature, wherein the join instruction may include a target blockchain network identification.
In some embodiments, the first node join request may also be checked. For example, target blockchain network information may be determined based on the target blockchain network identification; checking whether the first node joining request is legal or not based on the information of the node to be joined and the network information of the target block chain; if the first node join request is legitimate, step S120 is performed.
For example, when verifying whether the first node join request is legal, the BaaS platform may verify the content of the first node join request, for example, may verify a user name, a user identifier, a node identifier, a name of a to-be-joined block chain, an identifier of the to-be-joined block chain, or may verify information of the to-be-joined node based on a requirement of a target block chain network, so as to verify whether the information of the to-be-joined node meets the requirement of the target block chain network, where the requirement of the target block chain network may include one or more of a region requirement, a reputation requirement, a processing capability requirement, and the like, and may be specifically determined according to actual needs. If the verification is not legal, prompt information can be sent to the user equipment to prompt the user to modify the related parameters.
S120, generating a node configuration file according to the first node joining request, and sending the node configuration file to the node to be joined so that the node to be joined is configured according to the node configuration file;
determining network resources of a node to be added in the target block chain network based on the target block chain network information and the node to be added information; and generating a node configuration file based on the network resources so that the node to be added communicates in the target block chain network according to the network resources.
The content of the configuration file may include information such as a node identifier, a node type, a host name, and a domain name of the node to be added. The BaaS platform sends a node configuration file to a node to be added, so that the node to be added reads the configuration file, loads a corresponding plug-in the node, initializes a node program and the plug-in, then starts the node program and the plug-in, resets a network state and a communication protocol service state of the node, monitors and connects a blockchain network to be added, and can establish a secure communication channel with the blockchain network by using a technology meeting a password standard. In addition, the node to be added can generate a public key and private key pair, and the private key of the node to be added is stored in the encryption database, so that the security of the private key is ensured, the public key can be used for encryption, and the private key can be used for signature.
S130, sending a second node joining request to the target block chain network so that other nodes in the target block chain network communicate with the node to be joined based on the second node joining request.
The second node joining request may include notarization information of the BaaS platform. For example, the BaaS platform may sign the first node join request using a private key to obtain signature information; determining a second node joining request based on the first node joining request, the signature information and the public key.
For example, the first node join request may be digitally signed using RSA (Rivest Shamir Adleman), DSA (Digital Signature Algorithm), or ECDSA Elliptic curve Digital Signature Algorithm, etc., where ECDSA is a combination of ECC (Elliptic curve Cryptography) and DSA.
After each node in the block chain network receives the first node joining request, the signature information and the public key of the node to be joined, the public key of the node to be joined is used for decrypting the signature information to obtain decrypted summary information, then the HASH function is used for generating the summary information of the first node joining request, and the decrypted summary information is compared with the generated summary information, so that identity verification is carried out on the node to be joined. In addition, the initial information in the account book data can be compared, the validity of the first node joining request is verified, if the verification results of all nodes in the block chain network are agreed, the node to be joined is approved to join the block chain network after the identity of the node to be joined is confirmed, the node to be joined is added to the block chain member, the node identification is added to a local permission list, the record is submitted, and a new block is generated. And at this point, the node to be added is finally added into the block chain network. If the identity of the node to be joined is not confirmed, it is not allowed to join the blockchain network. And finally, the block chain network returns the adding result of the node to be added to the BaaS platform.
The BaaS platform can receive a verification result aiming at a second node joining request sent by other nodes in the target block chain network; and when the node to be joined is determined to fail to join based on the verification result, sending a rollback operation instruction to the node to be joined so that the node to be joined executes rollback operation.
In order to facilitate the user to intuitively know the joining state of the node to be joined, the BaaS platform may further display the joining state of the node to be joined, that is, the joining is successful or fails.
In addition, if the node to be added fails to join the blockchain, the BaaS platform may also send a rollback operation instruction to the node to be added, so that the node to be added executes a rollback operation, thereby recovering a state before the blockchain network to be added is connected. At this time, the BaaS platform may monitor the operating state of the node to be joined and send a prompt to the node to be joined.
When the node to be added in the embodiment is added into the blockchain, a user does not need to deeply know the blockchain technology, but a series of operations such as node configuration, addition request verification, node addition into the blockchain network and the like are realized through the BaaS platform, so that the user operation is reduced, the user can rapidly add into the blockchain ecology and participate in the blockchain transaction.
In addition, a series of operations such as node configuration, join request verification, node joining in a block chain network and the like can be realized through the BaaS platform, whether the node joins in the block chain or not can be displayed through the BaaS platform, and the running state of the node can be monitored. Even if the node is abnormal in the joining process, the node can be rolled back quickly without influencing the existing states of the node and the block chain. Visualization is realized through the BaaS platform in the whole operation process, so that the running state and the operation result of the node one-key adding process can be intuitively known in real time.
Fig. 2 is a schematic flow chart of another method for adding a blockchain according to an embodiment of the present invention. The method can be applied to a node to be added, and the node to be added can be matched with the BaaS platform to realize the addition of the block chain. As shown in fig. 2, the method comprises the steps of:
and S210, sending a first node joining request to the BaaS platform so that the BaaS platform generates a node configuration file according to the first node joining request.

And S220, receiving the node configuration file sent by the BaaS platform.
The configuration file is the same as the configuration file in the embodiment shown in fig. 1, and can be understood by referring to each other.
And S230, configuring according to the node configuration file so as to communicate in the target block chain network.
After the configuration is performed according to the configuration file, the node to be joined can be considered to have the capability of performing communication in the target blockchain network. For example, the configuration file may include network resources allocated to the to-be-joined node according to which the to-be-joined node may communicate in the target blockchain network.
For example, after the node to be joined reads the configuration file, the corresponding plug-in the node may be loaded, and the node program and the plug-in are initialized, and then the node program and the plug-in are started, the network state and the communication protocol service state of the node are reset, and then the node to be joined is monitored and connected to the blockchain network. Additionally, techniques that conform to cryptographic standards may be used to establish secure communication channels with the blockchain network. Meanwhile, the node to be added generates a public key and private key pair, and the private key of the public key and private key pair is stored in the encryption database, so that the safety of the private key is ensured.
In the embodiment, the node to be added realizes node configuration through the BaaS platform, a user does not need to deeply know the block chain technology, the operation of the user is reduced, and the user can conveniently and quickly add the block chain ecology.
In some embodiments, the method may further comprise the steps of:
step 1) receiving a rollback operation instruction sent by a BaaS platform;
and step 2) executing the rollback operation according to the rollback operation instruction so as to recover the state before connecting the to-be-added block chain network.
Fig. 3 is a schematic flow chart of another method for adding a blockchain according to an embodiment of the present invention. The method can be applied to nodes in a target block chain network, in the process of adding the block chain, the nodes in the target block chain network can also be called verification nodes or other nodes, and the verification nodes are matched with the nodes to be added and the BaaS platform to realize the addition of the block chain. As shown in fig. 3, the method comprises the steps of:
and S310, receiving a second node joining request sent by the BaaS platform. The second node join request includes the first node join request, signature information, and a public key.

after each node in the block chain network receives the first node joining request, the signature information and the public key of the node to be joined, the public key of the node to be joined is used for decrypting the signature information to obtain decrypted summary information, then the HASH function is used for generating the summary information of the first node joining request, and the decrypted summary information is compared with the generated summary information, so that identity verification is carried out on the node to be joined. In addition, the validity of the first node joining request can be verified by comparing the initial information in the ledger data.
S330, if the verification result is legal, adding the node to be added into the target block chain network based on the first node adding request.
If the verification results of the nodes in the blockchain network are agreed, the node to be added is approved to be added into the blockchain network after the identity of the node to be added is confirmed, the node to be added is added into the blockchain member, the node identification of the node to be added is added into a local permission list, a record is submitted, and a new block is generated. And at this point, the node to be added is finally added into the block chain network. If the identity of the node to be joined is not confirmed, it is not allowed to join the blockchain network. And finally, the block chain network returns the adding result of the node to be added to the BaaS platform. For example, whether the ratio of the node in the target block chain network to the node in the second node joining request that is verified as being legal reaches a preset value can be determined; and determining the identifier of the node to be added, and adding the identifier of the node to be added into a permitted node list of the target block chain network. The reaching of the preset value can be determined according to actual needs, for example, the reaching of the preset value can mean more than half of the number.
In the embodiment, the node to be added realizes node configuration through the BaaS platform, a user does not need to deeply know the block chain technology, the operation of the user is reduced, and the user can conveniently and quickly add the block chain ecology.
