[0002] A blockchain is a chain of blocks linked together using cryptographic methods. The data in each block of a blockchain is related to the data in the previous block. Therefore, it is impossible to cheat by tampering with the data in the blocks, ensuring that the data in any block is public and transparent, thus improving the security of input information.

[0003] Currently, blockchain frameworks can be embedded into cloud computing platforms, allowing users to operate on the blockchain through web interfaces by leveraging cloud service infrastructure.

[0004] However, the inventors discovered that the related technology has at least the following technical problems: cloud computing platforms may have vulnerabilities, which could reduce the security of the blockchain. Summary of the Invention

[0011] The blockchain creation method, apparatus, device, storage medium, and program products provided in this application, based on a foundational blockchain, involve sending the blockchain creation information and ring signature result from the blockchain creation request to the consortium node terminal specified in the request after the foundational blockchain node receives the request.

[0024] The connection between the basic blockchain node 101, user terminal 102, and consortium node terminal 103 can be either wired or wireless.

[0025] It is understood that the scenarios illustrated in the embodiments of this application do not constitute a specific limitation on the blockchain creation method. In other feasible implementations of this application, the above scenarios may include more or fewer components than illustrated, or combine some components, or split some components, or arrange different components, which can be determined according to the actual application scenario and are not limited here.

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

[0027] Figure 2 This is a flowchart illustrating the blockchain creation method provided in this application embodiment. The execution entity of this application embodiment may be... Figure 1 The basic blockchain nodes in the example are not specifically limited in this embodiment. Figure 2 As shown, the method includes:

[0028] S201: Receive a blockchain creation request sent by a user terminal. The blockchain creation request includes creation information and ring signature results. The creation information includes configuration parameters and alliance node identifiers.

[0029] In this step, a blockchain chain establishment request can be received by receiving messages, data packets, etc. sent by the user terminal. The ring signature result can include the result obtained by the user terminal using the public key of a known consortium node in the blockchain and its own private key to ring sign the chain establishment information.

[0030] The chain information can be generated by the user on the user terminal through data input, selection of drop-down menus, and selection of options.

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

[0032] This step may include encapsulating the chain establishment information and ring signature result according to a preset protocol and sending them to the consortium node terminal. The consortium node terminal verifies the ring signature result using the chain establishment information, the ring signature result, and the pre-known public keys of each consortium node. Verification involves checking whether the signature satisfies a specific mathematical relationship or equation to determine the correctness and authenticity of the signature, thus obtaining the verification result. The consortium node terminal can display the chain establishment information.

[0033] S203: Receive the decision results sent by each alliance node terminal based on the chain establishment information.

[0034] In this step, the decision result can be input by the user into the consortium node terminal, which then sends it to the base blockchain node using a preset communication protocol.

[0035] S204: If all decisions result in agreement, then a new blockchain is created using the configuration parameters.

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

[0037] As described in the above embodiments, this disclosure uses a basic blockchain as its foundation. After the basic blockchain node receives a blockchain creation request, it sends the creation information and ring signature result from the request to the consortium node terminal specified in the request. The consortium node terminal verifies the ring signature result and obtains the verification result. After successful verification, the creation information is output to obtain the user's input decision result. A new blockchain is established when all decision results are agreed upon. Since the new blockchain is created by the blockchain itself, the creation process is protected from external influences, increasing the security of the new blockchain creation. Furthermore, the use of ring signatures to verify the identity of the party proposing the creation of the new blockchain ensures the security of the initiation process of creating the new blockchain.

[0038] In one possible implementation, the configuration parameters correspond to the configuration type.

[0039] Configuration types include processor type, memory size, consensus algorithm type, and consortium identifier. Consensus algorithm types include Proof-of-Work, Proof-of-Stake, Practical Byzantine Fault Tolerance, and Delayed Proof-of-Work.

[0040] Accordingly, in step S204 above, if each decision result is in agreement, a new blockchain is created using each configuration parameter, including steps S204A1 and S204A2.

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

[0042] In this step, the smart contract template may contain data write locations corresponding to each configuration type. The configuration parameters are written to the corresponding data write 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 uncovered configuration types can use the default configuration parameters.

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

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

[0045] As can be seen from the description of the above embodiments, the present disclosure embodiments obtain 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 agreed.

[0046] In one possible implementation, if all decisions result in agreement, a new blockchain is created using each configuration parameter, including steps S204B1 to S204B3.

[0047] S204B1: If all decisions result in agreement, then find the smart contract template corresponding to the configuration parameters.

[0048] This step may include finding the corresponding smart contract template by configuring the parameters.

[0049] Specifically, this involves using configuration parameters to find the correspondence between preset configuration parameters and templates, thereby obtaining the corresponding smart contract template. The correspondence between configuration parameters and templates can be pre-configured by staff and written into the blockchain, stored in formats such as tables or files.

[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 step S204A1 above, and will not be repeated here.

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

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

[0054] As can be seen from the description of the above embodiments, the embodiments of this disclosure obtain the contract to be executed by finding the smart contract template corresponding to the configuration parameters and writing the configuration parameters into the smart contract template, and then executing the smart contract to be executed, thereby creating a new blockchain. This realizes the determination of the smart contract template by combining specific configuration parameters, making the smart contract template more compatible with the specific parameters and avoiding errors in the smart contract.

[0055] In one possible implementation, the configuration parameters also include the application scenario, business requirements, block type, blockchain architecture, and data structure.

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

[0057] S4B11: Based on the application scenario, business requirements, block type, blockchain architecture, and data structure, it searches for the corresponding smart contract template from the preset smart contract template library.

[0058] In this step, smart contract templates can have corresponding tags. This step can include finding smart contract templates with tags that match the application scenario, business requirements, block type, blockchain architecture, and data structure. This step can also include finding smart contract templates whose configuration parameters include the application scenario, business requirements, block type, blockchain architecture, and data structure, as the actual smart contract templates to be used.

[0059] As can be seen from the description of the above embodiments, the embodiments of this disclosure limit the application scenario, business requirements, block type, blockchain architecture and data structure in the configuration parameters, thereby using a smart contract template that meets the requirements of the application scenario, business requirements, block type, blockchain architecture and data structure, so that the resulting smart contract is more in line with the actual use requirements.

[0060] In one possible implementation, after sending the chain establishment information and ring signature result to the alliance node terminal corresponding to the alliance node identifier in step S202, the method further includes steps S210 to S214.

[0061] S210: Receive modification information and modified ring signature sent by at least one consortium node terminal based on chain establishment information and ring signature results.

[0062] In this step, the modified information can be user input on the consortium node terminal side, and the modified ring signature can be obtained by the consortium node terminal signing the modified information using its own stored private key and the public keys of each consortium node terminal.

[0063] S211: Send the modification information and modified ring signature to each alliance node terminal so that each alliance node terminal can verify 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 step S202 above, and will not be repeated here.

[0065] S212: Receive voting information sent by each alliance node based on the modified information.

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

[0067] S213: Determine the selected configuration parameters based on the voting information, chain building information, and modification information.

[0068] This step includes counting the number of votes corresponding to the chain-building information and the modification information. The configuration parameter in the information with the higher number of votes is determined as the selected configuration parameter. Alternatively, if the number of votes for the chain-building information is greater than the number of votes for the modification information, the configuration parameter in the chain-building information is used as the selected configuration parameter. If the number of votes for the modification information is greater than the number of votes for the chain-building information, the configuration parameter in the chain-building information is modified using the modification information to obtain the selected configuration parameter.

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

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

[0071] As can be seen from the description of the above embodiments, this disclosure embodiment receives modification information and modified ring signature sent by the alliance node terminal based on the chain establishment information and ring signature result, sends the modification information and modified ring signature to each alliance node terminal, and 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 parameter in the chain establishment information and modification information according to each voting information, and uses the selected configuration parameter to create a new blockchain, so as to realize that the alliance node terminal can modify the chain establishment information after receiving the chain establishment information.

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

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

[0074] This step may include reading the identifiers of the chain-building information and the identifiers of the modification information from the voting information. For each identifier of the chain-building information read, the count of the chain-building information identifiers is incremented by one; for each identifier of the modification information read, the count of the modification information identifiers is incremented by one. After reading all types of identifiers from the voting information and the modification information, the count of the chain-building information identifiers and the count of the modification information identifiers are obtained. Both the identifiers of the modification information and the identifiers of the chain-building information can be the hash values ​​of the corresponding blocks.

[0075] S2132: If the number of identifiers in the chain establishment information is greater than the number of identifiers in the modification information, then the configuration parameters in the chain establishment information will be selected as the selected configuration parameters.

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

[0077] S2133: If the number of identifiers in the modified information is greater than the number of identifiers in the chain establishment information, then the configuration parameters in the modified information will be determined as the selected configuration parameters.

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

[0079] S2134: If the number of identifiers in the modified information equals the number of identifiers in the chain-building information, then send a re-voting request to each alliance node. Receive new voting information sent by each alliance node based on the re-voting request.

[0080] In this step, when there are multiple blockchain creation information entries, the number of identifiers for each entry and the number of identifiers for each modification entry are equal. The re-voting request can be pre-set by staff, such as "If the votes are tied, please vote again" or "If the votes are tied, please negotiate and vote again." The method for receiving new voting information is similar to step S212 above and will not be repeated here.

[0081] As can be seen from the description of the above embodiments, the embodiments of this disclosure count the number of identifiers of chain-building information and the number of identifiers of modification information in each voting information, select the configuration parameters from the information with higher votes from the modification information and chain-building information as the configuration parameters to be used in practice, and vote again when the votes of the two types of information are the same to ensure that there are available configuration parameters.
