[0022] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required to be used in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0023] Currently, in a blockchain network, users can use the on-chain services of DAPPs running on blockchain node devices by paying a fee. That is to say, before using the on-chain services of DAPPs running on blockchain node devices, users need to pay a certain fee to the developers of the DAPPs. On this basis, how to use the on-chain services of DAPPs for free through payment by others has become a current research hotspot.

[0024] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the architecture of a data processing system disclosed in an embodiment of the present invention. As Figure 1 shown, the data processing system includes at least one blockchain node device, and the above at least one blockchain node device constitutes a blockchain network. Among them, any blockchain node device in the blockchain network can run a smart contract to provide on-chain services for the obtained transaction data. In a specific implementation process, after the blockchain node device receives the transaction data and the identity information about the transaction data, it can verify the identity information to obtain a verification result. If the verification result indicates that the verification is successful, it provides on-chain services for the transaction data through the decentralized application; if the verification result indicates that the verification fails, it refuses to provide on-chain services for the transaction data through the decentralized application, for example, deleting the transaction data and the identity information.

[0025] Optionally, the data processing system may further include a user device, and the user device can interact with the blockchain node device to update a preset database in the blockchain node device. Optionally, the user device can also interact with the blockchain node device to send virtual resources to the blockchain node device. Among them, the user device can be the paying party, that is, the party that pays the fee for the user to the blockchain node device.

[0026] Exemplarily, the transaction data may include a block query request and a height, and then the on-chain service may be to query the block according to the height. Another exemplarily, the transaction data may include transaction flow information, and then the on-chain service may be to chain the transaction flow information. It should be noted that the above are only examples and do not constitute a limitation on the embodiments of the present invention. For example, the transaction data may include a hash, and then the on-chain service may be to obtain the plaintext according to the hash, and so on.

[0027] Blockchain is a new application mode of computer technologies such as distributed data storage, consensus mechanism, and encryption algorithm. In essence, it is a decentralized database; a blockchain can be composed of multiple concatenated transaction records (also known as blocks) connected and protected by cryptography. The distributed ledger concatenated by the blockchain can enable multiple parties to effectively record transactions and can permanently verify this transaction (non-tamperable).

[0028] Among them, the consensus mechanism refers to a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in a blockchain network. The consensus mechanism is a mathematical algorithm commonly recognized by each node in the blockchain network. The consensus algorithms in the consensus mechanism include, but are not limited to, the Proof of Work (PoW) algorithm, the Proof of Stake (PoS) algorithm, the Delegated Proof of Stake (DPoS) algorithm, the Practical Byzantine Fault Tolerance (PBFT) algorithm, etc.

[0029] In the data processing process of this application, any blockchain node device in the blockchain network stores a smart contract, and they can provide on-chain services for transaction data by running the smart contract. Among them, a smart contract is a computer protocol designed to spread, verify, or execute a contract in an information-based manner, allowing for trusted transactions without a third party. These transactions are traceable and irreversible. A smart contract is a set of commitments defined in digital form, including the protocol on which the contract parties can execute these commitments, and is a piece of code written on the blockchain. The smart contract in the embodiment of the present invention can be understood as a DAPP.

[0030] Based on the above description, an embodiment of this application proposes a data processing method as Figure 2 shown, and this data processing method may include the following steps S201 - S203:

[0031] S201: The blockchain node device receives transaction data and identity information about the transaction data.

[0032] Among them, the identity information about the transaction data can be used to indicate the identity of the sender who sent the transaction data, and the identity information may include account information or device identification, etc.

[0033] For example, if the DAPP running in the blockchain node device only provides free on-chain services to VIP users, then after the user logs in through the account information of the instant messaging application on the terminal, the user can send transaction data and the account information to the blockchain node device through the terminal. The blockchain node device can determine whether the user is a VIP user based on the account information. If the user is a VIP user, the blockchain node device provides on-chain services for the transaction data through the DAPP.

[0034] For another example, if the DAPP running on the blockchain node device only provides free on-chain services to the employees of enterprise A, then after the user logs in through the employee's account information on the terminal, the user can send transaction data and the account information to the blockchain node device through the terminal. The blockchain node device can determine whether the user is an employee of enterprise A based on the account information. If the user is an employee of enterprise A, the blockchain node device provides on-chain services for the transaction data through the DAPP.

[0035] For another example, if the DAPP running on the blockchain node device only provides free on-chain services for the transaction data sent by the device corresponding to the target device identifier, then the device sends the transaction data and the device identifier of the device to the blockchain node device. The blockchain node device can determine whether the device is the device corresponding to the target device identifier based on the device identifier. If the device is the device corresponding to the target device identifier, the blockchain node device provides on-chain services for the transaction data through the DAPP.

[0036] In one implementation, the transaction data received by the blockchain node device can be input by the user or sent by the user to the blockchain node device through the terminal, which is not specifically limited by the embodiments of this application.

[0037] S202: The blockchain node device verifies the identity information to obtain a verification result.

[0038] In one implementation, the blockchain node device can compare the account information with at least one piece of account information in the preset database. If the account information exists in the preset database, a first verification result is generated, and the first verification result indicates successful verification. If the account information does not exist in the preset database, a second verification result is generated, and the second verification result indicates failed verification.

[0039] In one implementation, before the blockchain node device compares the account information with at least one piece of account information in the preset database, it can also receive database update information sent by the user device. The database update information includes target account information, and then updates at least one piece of account information in the preset database according to the target account information to obtain an updated database. Further, the blockchain node device can compare the account information with at least one piece of account information in the updated database.

[0040] For example, after user A becomes a VIP user, the user device can send the account information of the user to the blockchain node device so that the blockchain node device can add the account information to the preset database.

[0041] For another example, when user B leaves enterprise A, the user device can send the account information of user B to the blockchain node device so that the blockchain node device can delete the account information of user B from the preset database.

[0042] In one implementation, the database update information may further include a digital signature of the target account information, which is obtained by the user device signing the target account information using the private key of the user device. After receiving the database update information sent by the user device, the blockchain node device may further verify the digital signature using the public key of the user device. If the verification passes, it triggers the execution of updating at least one account information in the preset database according to the target account information to obtain an updated database.

[0043] S203: If the verification result indicates successful verification, the blockchain node device provides on-chain services for the transaction data through the decentralized application.

[0044] In the embodiments of the present application, the blockchain node device receives transaction data and identity information about the transaction data, verifies the identity information to obtain a verification result. If the verification result indicates successful verification, the blockchain node device provides on-chain services for the transaction data through the decentralized application, and can use the DAPP for free to provide on-chain services for the transaction data submitted by specific users.

[0045] Please refer to Figure 3 , Figure 3 which is another data processing method proposed based on the embodiments shown in Figure 2 This data processing method may include but is not limited to: S301 - S305.

[0046] S301: The blockchain node device receives transaction data and identity information about the transaction data.

[0047] For the specific description of step S301 in the embodiments of the present invention, please refer to the description of step S201 in the above embodiments, and the embodiments of the present invention will not be elaborated here.

[0048] S302: The blockchain node device verifies the identity information to obtain a verification result.

[0049] For the specific description of step S302 in the embodiments of the present invention, please refer to the description of step S202 in the above embodiments, and the embodiments of the present invention will not be elaborated here.

[0050] S303: The blockchain node device obtains virtual resources about the transaction data.

[0051] The virtual resources regarding the transaction data obtained by the blockchain node device can be those submitted by the user to the blockchain node device, or those submitted by the user device to the blockchain node device.

[0052] For example, the user device sends digital resources to the blockchain node device, so that the blockchain node device sends the virtual resources corresponding to the digital resources to the user device according to a preset exchange ratio. The user device can send the virtual resources to each user (such as VIP users or employees, etc.). When the user sends transaction data to the blockchain node device, the virtual resources regarding the transaction data can be sent to the blockchain node device.

[0053] Another example is that the user device sends digital resources to the blockchain node device, so that the blockchain node device sends the virtual resources corresponding to the digital resources to the user device according to a preset exchange ratio. After the user sends transaction data to the blockchain node device, the blockchain node device can request the virtual resources regarding the transaction data from the user device, and then the user device can send the virtual resources regarding the transaction data to the blockchain node device.

[0054] S304: The blockchain node device analyzes the transaction data to determine the first amount of virtual resources required to provide on-chain services for the transaction data.

[0055] The blockchain node device can analyze the transaction data, determine the business requirements regarding the transaction data, then determine the on-chain services that need to be provided for the transaction data based on the business requirements, and determine the first amount of virtual resources required for the on-chain services based on the determined on-chain services.

[0056] In one implementation, before the blockchain node device provides on-chain services for the transaction data through a DAPP, it can obtain the virtual resources regarding the transaction data, analyze the transaction data to determine the first amount of virtual resources required to provide on-chain services for the transaction data.

[0057] In one implementation, before the blockchain node device obtains the virtual resources regarding the transaction data, it can receive the device identifier of the user device. Based on this, the way for the blockchain node device to obtain the virtual resources regarding the transaction data can be: the blockchain node device sends a first virtual resource acquisition request to the user device corresponding to the device identifier, and receives the virtual resources sent by the user device in response to the first virtual resource acquisition request.

[0058] In one implementation, before the blockchain node device obtains virtual resources regarding the transaction data, it may also receive a second virtual resource acquisition request sent by a user device. The second virtual resource acquisition request carries a second virtual resource quantity. If it is detected that the user device transfers the digital resources corresponding to the second virtual resource quantity from the management account of the user device to the associated account of the blockchain node device, the blockchain node device sends virtual resources with the quantity of the second virtual resource quantity to the user device.

[0059] S305: If the verification result indicates successful verification and the virtual resource quantity of the virtual resources is greater than or equal to the first virtual resource quantity, the blockchain node device provides on-chain services for the transaction data through the decentralized application.

[0060] In the embodiments of the present application, the blockchain node device receives transaction data and identity information regarding the transaction data, verifies the identity information to obtain a verification result. If the verification result indicates successful verification and the obtained virtual resource quantity of the virtual resources is greater than or equal to the first virtual resource quantity, the blockchain node device provides on-chain services for the transaction data through the decentralized application, and can provide on-chain services for the transaction data submitted by a specific user to the DAPP for free through the way of payment on behalf.
