[0026] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0027] Figure 2 A flowchart of a blockchain creation method provided in an embodiment of the present application. The execution subject of the embodiment of the present application may be Figure 1 The basic blockchain nodes in this embodiment are not particularly limited. Figure 2 As shown, the method includes:

[0028] S201: receiving a blockchain establishment request sent by a user terminal, wherein the blockchain establishment request includes chain establishment information and a ring signature result, wherein the chain establishment information includes configuration parameters and an alliance node identifier.

[0029] In this step, the blockchain establishment request may be received by receiving a message, a data packet, or the like sent by a user terminal, and the ring signature result may include the result obtained by the user terminal using the public key of a known alliance node in the blockchain and its own private key to sign the chain establishment information ring.

[0030] The link establishment information may be generated by the user in a user terminal by inputting data, selecting a drop-down menu, checking an option, etc.

[0031] S202: Send the chain establishment information and the ring signature result to the alliance node terminal corresponding to the alliance node identifier, so that the alliance node terminal verifies the ring signature result and obtains the verification result. If the verification result is normal, the chain establishment information is output.

[0032] In this step, the chain building information and the ring signature result may be encapsulated according to a preset protocol and sent to the alliance node terminal. The alliance node terminal verifies the ring signature result through the chain building information, the ring signature result and the public keys of each alliance node known in advance. During the verification, the correctness and authenticity of the signature are determined by checking whether the signature satisfies a specific mathematical relationship or equation to obtain a verification result. The alliance node terminal can display and output the chain building information.

[0033] S203: receiving the decision results sent by each alliance node terminal according to the link establishment information.

[0034] In this step, the decision result can be input by the user into the alliance node terminal, and sent to the basic blockchain node by the alliance node terminal using a preset communication protocol.

[0035] S204: If the decision results are in agreement, a new blockchain is created using the configuration parameters.

[0036] In this step, for example, there are currently 5 alliance node identifiers corresponding to 5 alliance node terminals, and the decision results received from these 5 alliance node terminals are all agreed, then a new blockchain is created using the configuration parameters.

[0037] From the description of the above embodiments, it can be seen that the embodiments of the present disclosure take the basic blockchain as the basis. After the basic blockchain node receives the blockchain chain building request, the chain building information and the ring signature result in the blockchain chain building request are sent to the alliance node terminal specified in the blockchain chain building request. The ring signature result is verified by the alliance node terminal to obtain the verification result. After the verification is passed, the chain building information is output to obtain the decision result input by the user. When the decision results are all agreed, a new blockchain is established. Since the new blockchain is established by the blockchain, it is guaranteed that the establishment process of the new blockchain will not be affected by the outside world, which increases the security of the establishment of the new blockchain. At the same time, since the ring signature method is used to authenticate the identity of the party proposing the construction of the new blockchain, the security of the initiation process of creating the new blockchain is guaranteed.

[0038] In a possible implementation, the configuration parameter corresponds to the configuration type.

[0039] Among them, configuration types include processor type, memory size, consensus algorithm type, alliance party identification, etc. Consensus algorithm types include proof of work, proof of stake, practical Byzantine fault tolerance, delayed proof of work, etc.

[0040] Correspondingly, in the above step S204, if the decision results are agreed, a new blockchain is created using the configuration parameters, including: step S204A1 and step S204A2.

[0041] S204A1: If the decision results are in agreement, the configuration parameters are written into the smart contract template according to the configuration type corresponding to the configuration parameters to obtain a smart contract to be executed.

[0042] In this step, the smart contract template may have data writing locations corresponding to each configuration type, and the configuration parameters are written into the corresponding data writing locations to obtain the smart contract to be executed. If the configuration parameters do not cover all configuration types in the smart contract template, the configuration types not covered can use the default configuration parameters.

[0043] S204A2: Execute the pending smart contract to create a new blockchain.

[0044] This step may include executing the code in the smart contract to create a new blockchain.

[0045] From the description of the above embodiments, it can be seen that the embodiment of the present disclosure obtains a smart contract to be executed by writing the configuration parameters into the position of the corresponding configuration type in the smart contract template when the decision result is consent.

[0046] In a possible implementation, if the decision results are in agreement, a new blockchain is created using the configuration parameters, including steps S204B1 to S204B3.

[0047] S204B1: If the decision results are in agreement, then find the smart contract template corresponding to the configuration parameters.

[0048] In this step, the corresponding smart contract template may be searched through the content of the configuration parameters.

[0049] Specifically, it includes using configuration parameters, finding the correspondence between preset configuration parameters and templates, and obtaining the corresponding smart contract template. The correspondence between configuration parameters and templates can be pre-configured by staff and written into the blockchain, and stored in a format such as a table or file.

[0050] S204B2: Write the configuration parameters into the smart contract template to obtain the smart contract to be executed.

[0051] This step is similar to the above step S204A1 and will not be described again here.

[0052] S204B3: Smart pending execution of smart contracts to create new blockchains.

[0053] This step is similar to the above step S204A2 and will not be repeated here.

[0054] From the description of the above embodiments, it can be seen that the embodiments of the present disclosure obtain the contract to be executed by searching for the smart contract template corresponding to the configuration parameters, write the configuration parameters into the smart contract template, execute the smart contract to be executed, thereby creating a new blockchain, and determining the smart contract template in combination with specific configuration parameters, so that the smart contract template better matches the specific parameters and avoids errors in the smart contract.

[0055] In one possible implementation, the configuration parameters also include application scenarios, business requirements, block types, blockchain architecture, and data structures.

[0056] In the above step S204B1, searching for the smart contract template corresponding to the configuration parameters includes: step S4B11.

[0057] S4B11: Use application scenarios, business requirements, block types, blockchain architecture and data structures to find the corresponding smart contract template from the preset smart contract template library.

[0058] In this step, the smart contract template may have corresponding tags, and this step may include searching for smart contract templates with tags that are the same as the application scenario, business requirements, block type, blockchain architecture, and data structure. This step may also include searching for smart contract templates with application scenarios, business requirements, block types, blockchain architecture, and data structures in the configuration parameters as the actual smart contract templates used.

[0059] From the description of the above embodiments, it can be seen that the embodiments of the present disclosure limit the application scenarios, business requirements, block types, blockchain architectures and data structures in the configuration parameters, thereby using smart contract templates that meet the application scenarios, business requirements, block types, blockchain architectures and data structure requirements, so that the resulting smart contracts are more in line with actual usage requirements.

[0060] In a possible implementation, after the chain establishment information and the ring signature result are sent to the alliance node terminal corresponding to the alliance node identifier in the above step S202, the following steps are further included: step S210 to step S214.

[0061] S210: Receive modification information and modified ring signature sent by at least one alliance node terminal according to the chain establishment information and the ring signature result.

[0062] In this step, the modification information may be input by a user on the alliance node terminal side, and the modification ring signature may be obtained by the alliance node terminal using its own stored private key and the public keys of each alliance node terminal to sign the modification information.

[0063] S211: Send the modification information and the modified ring signature to each alliance node terminal, so that each alliance node terminal verifies the modified ring signature. If the verification result of the modified ring signature is normal, output the modification information.

[0064] This step is similar to the above step S202 and will not be repeated here.

[0065] S212: receiving voting information sent by each alliance node according to the modified information.

[0066] This step is similar to the process of receiving the decision result in the above step S203, and will not be repeated here.

[0067] S213: Determine the selected configuration parameters according to the voting information, link building information and modification information.

[0068] In this step, it includes counting the number of votes corresponding to the link establishment information and the modification information, and determining the configuration parameters in the information with a higher number of votes as the selected configuration parameters. Alternatively, if the number of votes for the link establishment information is greater than the number of votes for the modification information, the configuration parameters in the link establishment information are used as the selected configuration parameters. If the number of votes for the modification information is greater than the number of votes for the link establishment information, the modification information is used to modify the configuration parameters in the link establishment information to obtain the selected configuration parameters.

[0069] S214: Create a new blockchain using the selected configuration parameters.

[0070] This step is similar to the above step S204 and will not be repeated here.

[0071] From the description of the above embodiments, it can be seen that the embodiment of the present disclosure receives the modification information and the modified ring signature sent by the alliance node terminal according to the chain building information and the ring signature result, and sends the modification information and the modified ring signature to each alliance node terminal. After the alliance node terminal verifies the modified ring signature and the verification result is normal, it outputs the modification information, receives the voting information sent by the modification information, determines the selected configuration parameters in the chain building information and the modification information according to the voting information, and creates a new blockchain using the selected configuration parameters, so that the alliance node terminal can modify the chain building information after receiving the chain building information.

[0072] In a possible implementation, in the above step S213, based on each voting information, the selected configuration parameters are determined in the link building information and the modification information, including: steps S2131 to S2134.

[0073] S2131: Count the number of identifiers of the link-building information and the number of identifiers of the modification information in each voting information.

[0074] In this step, it may include reading the identifier of the chain building information and the identifier of the modification information in the voting information, and adding one to the number of identifiers of the chain building information for each identifier of the chain building information read, and adding one to the number of identifiers of the modification information for each identifier of the modification information read, and after reading all the identifiers in the voting information and the modification information, the number of identifiers of the chain building information and the number of identifiers of the modification information are obtained. The identifier of the modification information and the identifier of the chain building information can both be the hash value of the corresponding block.

[0075] S2132: If the number of identifiers in the link building information is greater than the number of identifiers in the modification information, the configuration parameters in the link building information are determined as selected configuration parameters.

[0076] In this step, for example, if the number of identifiers in the link establishment information is 5 and the number of identifiers in the modification information is 4, the configuration parameters in the link establishment information are determined as the selected configuration parameters. For another example, if the number of identifiers in the link establishment information is 7 and the number of identifiers in the modification information is 2, the configuration parameters in the link establishment information are determined as the selected configuration parameters.

[0077] S2133: If the number of identifiers in the modification information is greater than the number of identifiers in the link establishment information, the configuration parameters in the modification information are determined as selected configuration parameters.

[0078] In this step, for example, if the number of identifiers in the link building information is 3 and the number of identifiers in the modification information is 9, the configuration parameters in the modification information are determined as the selected configuration parameters. For another example, if the number of identifiers in the link building information is 5 and the number of identifiers in the modification information is 7, the configuration parameters in the modification information are determined as the selected configuration parameters. For another example, if the number of identifiers in the link building information is 3 and the number of identifiers in the modification information A is 2, the configuration parameters in the modification information are determined as the selected configuration parameters, and the number of identifiers in the modification information B is 11, the configuration parameters in the modification information B are determined as the selected configuration parameters.

[0079] S2134: If the number of identifiers in the modified information is equal to the number of identifiers in the link establishment information, a re-voting request is sent to each alliance node, and new voting information sent by each alliance node according to the re-voting request is received.

[0080] In this step, when there are multiple link building information, the number of identifiers of each link building information and the number of identifiers of the modification information are equal, and the re-voting request can be preset by the staff, such as "please vote again if the number of votes is the same", "please vote again after negotiation if the number of votes is the same", etc. The method of receiving new voting information is similar to the above step S212, which will not be repeated here.

[0081] From the description of the above embodiments, it can be seen that the embodiments of the present disclosure count the number of identifiers of the link building information and the number of identifiers of the modification information in each voting information, and select the configuration parameters in the information with higher votes from the modification information and the link building information as the configuration parameters actually used. If the votes of the two types of information are the same, voting is performed again to ensure that there are available configuration parameters.
