Firstly, illustratively in block chain intelligent contract function, intelligent contract can be understood from two angles.From
For user perspective, intelligent contract is typically considered the program of an automatic security account, for example, when specific condition meets
When, which will discharge and shift fund.Technically, intelligent contract may be considered as network server,
Only intelligent contract is not to be set up on the internet using IP address, but be erected on block chain, so as on it
Face runs specific program.In addition, the code and state of intelligent contract do not depend on some specific hardware and set all on block chain
It is standby.And the execution of the program code in intelligent contract is become by people's triggering or successful execution or all states
Change and all cancels (including the information sent or received from the contract currently to fail).
And order fund intelligence contract and order data intelligence contract are all to have above-mentioned intelligence to close in the embodiment of the present invention
Function about.
