In this embodiment, a specific application scenario is given, in an internet of things environment, a plurality of devices simultaneously accessing a same internet of things platform have different data access protocols, and a problem occurs when data interaction is performed between two devices having different data access protocols, in this case, a data processing party (i.e., a party that performs mutual conversion on different data access protocols) triggers a protocol conversion instruction, receives the protocol conversion instruction through a protocol conversion program based on an intelligent contract, obtains a transaction corresponding to the protocol conversion instruction, and further, if it is determined that the transaction corresponding to the protocol conversion instruction is a protocol conversion transaction, it indicates that the transaction that the data processing party wants to do is to perform mutual conversion on different data access protocols, and the protocol conversion program based on the intelligent contract sends the protocol conversion transaction to a target block chain, thereby performing a process of performing mutual conversion on different data access protocols, this process is described in detail in the examples below.
Step S20, executing the operation function corresponding to the protocol conversion transaction to trigger the target intelligent contract corresponding to the protocol conversion transaction, and downloading the protocol conversion service in the target intelligent contract.
In this embodiment, a plurality of target intelligent contracts are deployed in a target blockchain, a protocol conversion service written by a plurality of parties (which may be device parties having different data access protocols) exists in a target intelligent contract, and after a protocol conversion transaction is sent to the target blockchain, an operation function corresponding to the protocol conversion transaction needs to be executed to trigger the target intelligent contract corresponding to the protocol conversion transaction, it is known that the operation function is completed by related nodes (nodes related to data access protocol conversion) on the target blockchain together, so that data consistency in a blockchain network of the target blockchain is ensured, and the target intelligent contract includes wisdom and heartburn of a data processing party, and therefore, a condition for triggering the intelligent contract may be set as payment, that is, the operation function corresponding to the protocol conversion transaction is executed to determine the target intelligent contract corresponding to the protocol conversion transaction, and outputting payment information, and triggering the target intelligent contract after the user who wants to download the protocol conversion service in the target intelligent contract completes payment, thereby downloading the protocol conversion service.

The intelligent contract returns an address when deployed on the blockchain, each address corresponds to a protocol conversion transaction, the intelligent contract is uniquely called through the address, each contract defines a specific conversion method of the protocol, the conversion method is defined through an operation function, after the calling, a predefined trigger condition (for example, a payment mechanism) in the intelligent contract triggers a response (for example, downloading), that is, the conversion method is downloaded to the local, and after the target intelligent contract is downloaded, conversion between different data access protocols is completed by running a protocol conversion service corresponding to the protocol conversion transaction in the target intelligent contract, as can be known, the protocol conversion service in the embodiment includes a conversion method between different data access protocols, either between two data access protocols or between multiple data access protocols, one intelligent contract can be written with only one protocol conversion service or a plurality of protocol conversion services, and when a user who wants to convert different data access protocols downloads and runs the protocol conversion service in the target intelligent contract, the user can autonomously complete the conversion of the different data access protocols.
Specifically, the step of S20 refinement includes:
step a1, executing the operation function corresponding to the protocol conversion affair, and searching the target intelligent contract corresponding to the protocol conversion affair in the target block chain.
Step a2, downloading the protocol conversion service in the target intelligent contract when receiving the trigger instruction corresponding to the target intelligent contract.

It can be known that, after sending the protocol conversion transaction to the target block chain, the target intelligent contract corresponding to the protocol conversion transaction needs to be triggered by executing the operation function corresponding to the protocol conversion transaction, and the method for finding the deployed target intelligent contract in the target block chain is that, first, the target protocol to be converted and the target conversion protocol included in the protocol conversion transaction are queried, wherein the target conversion protocol is a protocol converted from the target protocol to be converted, the direction of protocol conversion is defined, i.e. from the target protocol to be converted to the target conversion protocol, and the target protocol to be converted and the target conversion protocol are two different data access protocols, then, screening is performed in the target block chain to screen out the first intelligent contract in the target block chain, wherein the first intelligent contract is written with the first protocol conversion service, and the first protocol conversion service includes a method for converting the first protocol to be converted into the first conversion protocol, the first protocol to be converted is the same as the target protocol to be converted, the first conversion protocol is the same as the target protocol to be converted, the first protocol to be converted and the first conversion protocol are two different data access protocols, and the direction of protocol conversion is also specified, namely the first protocol to be converted is the first conversion protocol, namely, the protocol correspondence is the same, namely, the condition of screening out the target intelligent contract corresponding to the protocol conversion transaction from the target block chain.
In this embodiment, when a protocol conversion program based on an intelligent contract receives a protocol conversion instruction, a protocol conversion transaction corresponding to the protocol conversion instruction is acquired, the protocol conversion transaction is sent to a target block chain, a target intelligent contract corresponding to the protocol conversion transaction is triggered by executing an operation function corresponding to the protocol conversion transaction in the target block chain, the target intelligent contract is downloaded, and finally, protocol conversion is completed by operating a protocol conversion service corresponding to the protocol conversion transaction in the target intelligent contract.

Specifically, steps subsequent to step S10 include:
and e1, querying the consensus node, and determining whether the consensus node stores the operation function corresponding to the protocol conversion transaction.
Step e2, if the common node stores the operation function and receives the trigger instruction corresponding to the operation function, acquiring the operation function to execute the operation function.
