The server can be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, taking the application of the method to the server in fig. 1 as an example for explanation, the method includes the following steps:
s10: an original intelligent contract is obtained, the original intelligent contract comprising a logical contract and a data contract address.
A Smart contract (Smart contract), among others, is a computer protocol for propagating, verifying or executing contracts in an informative manner, i.e., a piece of code written on a blockchain in an ethernet design. The original intelligent contract in this embodiment is an intelligent contract that needs data separation, that is, an unprocessed intelligent contract, and includes a logic contract, a data contract, and a data contract address, where the logic contract includes a service code of a system and corresponding data, and is used to implement a specific service function requirement in an ethernet intelligent contract. The data contract address is a data read-write interface and is used as an entrance for accessing the logic contract.
Specifically, the original intelligent contract may be obtained through address instantiation call, and the specific implementation process is as follows: extracting the address of the deployed intelligent contract, then locally obtaining abi codes corresponding to the address of the intelligent contract, instantiating the intelligent contract through abi codes, wherein the instance can use the instance during deployment, and finally the intelligent contract instantiated by calling the address is the original intelligent contract.
S20: based on the data contract address, splitting the logic contract into M sub-logic contracts and M-type contract data which are in one-to-one correspondence with the M sub-logic contracts according to a preset function type in an address calling mode, wherein M is a natural number larger than 1.
The preset function type refers to a type of a function preset according to an application scene of the intelligent contract, M is the number of the preset function types, and the preset function types can be set according to actual needs, for example, the preset function includes 2 business function types including transaction transfer and transaction credit authorization, and at this time, M is 2. The sub-logical contract refers to a split logical contract with only one business function, such as a sub-logical contract with a transaction transfer business function. The contract data refers to data stored in the sub-logic contracts, and the categories of the contract data correspond to the sub-logic contracts one by one, namely the number of the categories of the contract data is M. The address calling mode refers to a mode of reading and writing data in a logic contract by calling a read and write interface (get function and set function) of a data field provided in a data contract address through the data contract address. In this embodiment, the logic contract is split by means of address calling. Specifically, after a logical contract is called according to a contract data address, data in the logical contract is split according to a function preset by the logical contract, so that M sub-logical contracts and M-class contract data corresponding to each sub-logical contract can be obtained. The method comprises the steps of generating a logic contract, generating a service code according to the service code, and dividing the logic contract into a plurality of logic contracts according to the service code, wherein the logic contract comprises data and service codes, and the logic contract comprises the data and the service code, so that the data of the logic contract is increased along with the increase of the service time of the intelligent contract, and the read-write efficiency of the data in the intelligent contract is influenced.

It can be understood that when an old contract is attacked, the property loss of a user is caused, and therefore, address updating is performed on each sub-logic contract in a proxy calling manner to obtain M target sub-logic contracts, that is, in a nameless function (Fallback function), a delagetecall function is used to cooperate with a defined logic contract address variable to perform proxy calling on the logic contract, which is beneficial to ensuring the accuracy and safety of intelligent contract-based transactions, so that the intelligent contract is safe and accurate under the condition of updating or upgrading.

S22: and splitting the target logic contract according to the preset function category to obtain M sub-agent logic contracts.
Specifically, the target contract is decomposed into a plurality of sub-agent logical contracts according to the preset function categories, and the specific decomposition method is consistent with the splitting method in step S20, and is not described herein again.

In an embodiment, as shown in fig. 4, in step S30, address updating is performed on each sub-logic contract in a proxy call manner to obtain M target sub-logic contracts, which specifically includes the following steps:
s31: the delegatecall opcode of the sub-logic contract is obtained.
Where the delegatecall opcode is a code at a target address provided by the EVM, is a call opcode executed in the context of a call logic contract, for updating a logic contract in an intelligent contract. In particular, the delegatecall operation code of a sub-logic contract may be extracted from a storage structure of the sub-logic contract.
S32: and updating the address of each sub-logic contract by adopting the delegatecall operation code to obtain the target sub-logic contract.
Specifically, the server updates the address of each sub-logical contract using the delegatecall opcode and sends a function call request to the address of the sub-logical contract that can be updated. Since the delegatecall can keep the state of function call, the logic of the target function can be updated, the state can be kept in the address of the generation sub-logic contract for the logic of the updatable sub-logic contract, and since the delegatecall operation code can keep the call of each sub-logic contract address, the updating of each sub-logic contract is realized, the target sub-logic contract is obtained, and the accuracy of the target sub-logic contract is ensured.
