The scheme of the embodiment of the present invention can be by being executed based on the transactions requests processing unit of intelligent contract, which can It is realized, and can be integrated in the calculating equipment of carrying block chain link point by the way of hardware and/or software.Referring to Fig. 1, the party Method can specifically include:

S110 generates the transactions requests based on Intelligent target contract.

In the present embodiment, intelligent contract, which refers to, to be called based on what Plugin Mechanism was write for the node in block chain network And the code segment executed, the execution of an intelligent contract can be achieved at least one function or handle a kind of transactions requests；It can be It makes an appointment, is stored in wound generation block when block chain creation；It can also be and create what process dynamics added in block chain, It is stored in a certain block；It is local that block chain node can also be stored in independently of block chain.Optionally, block chain node can portion Multiple intelligent contracts are affixed one's name to, different intelligent contracts can correspond to different functions.Intelligent target contract refers to that localized nodes are disposed Intelligent contract in one.

Transactions requests can be the locally generated issued transaction demand of localized nodes, or receive a certain trigger mechanism such as When the issued transaction demand that three method, apparatus (such as client, terminal device or server) are sent, according to the issued transaction demand Intelligent target contract is determined, then based on other sections for being used to request caused by the Intelligent target contract in block chain network Point, as current block chain generates the request of certain affairs of node processing.

For example, localized nodes are detecting that user clicks affairs button event on localized nodes, it is determined that generate affairs Process demand；Issued transaction demand interface can be showed to user later, and according to the input and/or selection of acquired user Operation, determines Intelligent target contract；And then generate the transactions requests based on the Intelligent target contract.

If localized nodes according to user input, determine invocation target intelligence contract " contract.add " to count into Row plus 1 processing, then the generated transactions requests based on Intelligent target contract are as follows:

S120 carries out pre-execution operation to transactions requests according to local data, determines input dependence data acquisition system and output Change data acquisition system.

In the present embodiment, local data is the localization data of block chain node.Optionally, if localized nodes are general areas Block chain node then directly can get the data from local；If localized nodes are lightweight node, can be from block link network Other nodes in network obtain local data.
