It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one

As shown in fig. 1, the method may specifically include:
s110, extracting a target contract name of a target intelligent contract from the contract deployment demand under the condition that the contract deployment demand is determined; inquiring from a block chain network according to the target contract name to obtain a historical mapping relation associated with the target contract name; and generating a target contract version of the target intelligent contract according to the historical contract version in the historical mapping relation.
In this embodiment, the contract deployment requirement refers to a requirement that requires contract deployment, and may include an intelligent contract file including a target intelligent contract; the target intelligent contract refers to an intelligent contract written by a user, and may include a target contract name and further a target contract version.
Specifically, when a user has a demand for deploying a target intelligent contract, the contract deployment demand is sent to a block chain platform; correspondingly, the blockchain platform determines a target contract name and a target contract version of the target intelligent contract according to the contract deployment requirement when receiving the contract deployment requirement, namely under the condition that the contract deployment requirement is determined to be possessed.
According to an optional mode, a target contract name of a target intelligent contract can be extracted from contract deployment requirements, then, according to the target contract name, a historical mapping relation associated with the target contract name is obtained through query from a block chain network, and then, according to a historical contract version in the historical mapping relation, a target contract version of the target intelligent contract is generated.
The historical mapping relation refers to the mapping relation among the target contract name, the historical contract version and the historical contract address stored in the block chain network. It should be noted that the contract names of different versions of the intelligent contract stored in the blockchain network are not changed.

For example, the target contract version of the target intelligent contract is generated according to the historical contract version in the historical mapping relationship, and if the target contract version of the target intelligent contract is extracted after analyzing the contract deployment requirement, whether the target contract version exists in the same historical contract version of the target intelligent contract or not is searched from the historical mapping relationship; if so, the target contract version is substituted for the historical contract version.
For example, the target contract version of the target intelligent contract is generated according to the historical contract version in the historical mapping relationship, and if the target contract version of the target intelligent contract is not extracted after the analysis on the contract deployment requirement, the version obtained by adding 1 to the historical contract version of the highest version in the historical mapping relationship may be used as the target contract version of the target intelligent contract.

Optionally, when determining that the historical contract relationship associated with the target contract name is stored in the block chain network according to the target contract name, identifying whether the target contract version is the same as the historical contract version in the historical contract relationship, and if so, replacing the historical contract relationship with the target contract version and the target contract relationship among the target contract addresses fed back by the block chain link points. And if not, storing the target mapping relation into the block chain network.
It should be noted that the mapping relation recording method and the mapping relation querying method in this embodiment are pre-stored in the pre-compilation contract, and when the block chain platform has a mapping relation recording or mapping relation querying requirement, the mapping relation method or the mapping relation querying method in the pre-compilation contract is automatically invoked to perform the mapping relation recording or querying.
