The intelligent contract calling method is applied to a blockchain network in a blockchain application system, the blockchain application system further includes at least one user side interacting with the blockchain network, as shown in fig. 1, the method includes the following steps S101 to S105:
s101, receiving a first uplink request sent by any user side, wherein the first uplink request is used for intelligent contract invoking.
Among them, a Smart contract (Smart contract in english) is a computer protocol that propagates, verifies, or executes contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The intelligent contract calling refers to that on a block chain, some functions cannot be completed through one intelligent contract, and at the moment, the calling among the intelligent contracts is used, namely the calling of the intelligent contracts is realized.
Specifically, in the intelligent contract calling, when a user side corresponding to an intelligent contract calling initiating end performs intelligent contract calling, a first uplink request is initiated first, the first uplink request is used for intelligent contract calling, and after a block chain network receives the first uplink request initiated by the user side, the block chain network checks the first uplink request and judges whether the verification of the first uplink request passes.
S102, judging whether the verification of the first uplink request is passed.
S103, if the verification of the first uplink request is passed, triggering the intelligent contract to call.
And S104, returning the intelligent contract to the user side according to a trigger instruction, and reporting an intelligent contract calling chain to a preset memory in a block chain so as to enable the memory to persistently store the intelligent contract calling chain, wherein the intelligent contract calling chain refers to calling information data corresponding to the intelligent contract calling.
S105, if the verification of the first uplink request is not passed, returning a prompt of failure of the verification of the first uplink request.
And the intelligent contract calling chain refers to calling information data corresponding to the intelligent contract calling.
Specifically, the blockchain network verifies the first uplink request, determines whether the verification of the first uplink request passes, allows the ue to perform intelligent contract calling if the blockchain network determines that the verification of the first uplink request passes, triggers the intelligent contract calling, and returns the intelligent contract to the ue according to a triggering instruction, meanwhile, reporting the intelligent contract calling chain corresponding to the intelligent contract calling to a preset memory in a block chain so as to enable the preset memory to store calling information data corresponding to the intelligent contract calling, thereby facilitating querying and tracking the intelligent contract invocation information, and causing the memory to persistently store the intelligent contract invocation chain, due to the consensus mechanism of the block chain network, the disclosure and transparency of intelligent contract calling can be ensured.
Further, in an embodiment, the step of determining whether the verification of the first uplink request is passed includes:
verifying the user identity contained in the first uplink request;
and if the user identity passes the verification, judging that the first uplink request passes the verification.
Specifically, the block chain network receives a first uplink request sent by a user side, judges whether the verification of the user identity contained in the first uplink request is passed, for example, the communication party identity and the signature user identity are verified to be legal, if the communication party identity and the signature user identity are legal, the verification of the first uplink request is passed, triggers the intelligent contract calling, for example, triggers the corresponding intelligent contract calling according to the set interface rule after the verification is passed, and therefore the safety of the intelligent contract calling in the block chain network is ensured through multi-level user identity validity verification.
The block chain application system further comprises at least one user side which interacts with the block chain network, receives a first uplink request sent by any user side through the block chain network, the first uplink request is used for intelligent contract calling, judges whether verification of the first uplink request passes or not, triggers the intelligent contract calling if the verification of the first uplink request passes, returns the intelligent contract to the user side according to a triggering instruction, and reports the intelligent contract calling chain corresponding to the intelligent contract calling to a preset memory in the block chain so as to enable the memory to persistently store the intelligent contract calling chain. Because the intelligent contract calling chain is reported to the preset memory in the block chain, so that the memory stores the intelligent contract calling chain persistently, the openness and transparency of the intelligent contract calling in the block chain can be improved, and the controllability of the intelligent contract calling in the block chain is improved.
Further, the method further comprises: and carrying out consensus and block-out on the called intelligent contracts.
Wherein consensus refers to a consensus mechanism, the so-called consensus mechanism is equivalent to voting, and different consensus mechanisms are equivalent to different voting rules. And the block outputting means that the data in the block chain is output to a user side outside the block chain.
Specifically, the called intelligent contracts are subjected to consensus and block identification to complete verification of data in the block chain, so that the safety of the data in the block chain can be ensured.
In one embodiment, after the step of returning the intelligent contract to the user side and reporting the intelligent contract call chain to a preset memory in a block chain, the method further includes:
receiving a query request for the intelligent contract calling chain sent by any user side;
calling the intelligent contract calling chain according to the query request;
and returning the intelligent contract calling chain to the user side corresponding to the query request.
Specifically, in the intelligent contract calling, if a first uplink request called by an intelligent contract sent by a user end is verified, the block chain network calls the intelligent contract and returns the intelligent contract to the user end, and simultaneously reports the intelligent contract calling chain to a preset memory in the block chain, so that after the memory persistently stores the intelligent contract calling chain, the block chain network receives a query request sent by any user end for the intelligent contract calling chain, calls the intelligent contract calling chain from the preset memory according to the query request, and returns the intelligent contract calling chain to the user end corresponding to the query request, so as to realize that the any user end queries the calling information data corresponding to the intelligent contract calling, because the intelligent contract calling chain is persistently stored in the preset memory, thereby realizing the disclosure and transparency of the intelligent contract calling chain.

s209, returning the intelligent contract calling chain to the user side corresponding to the query request
S210, if the verification of the second uplink request is not passed, returning a prompt that the verification of the second uplink request is failed.
Specifically, when any user terminal makes an inquiry request for the intelligent contract calling chain stored in the blockchain network, the blockchain network verifies the second uplink request, determines whether the verification of the second uplink request is passed, that is, determines whether the verification of the user terminal is passed, if the verification of the user terminal is passed, calls the intelligent contract calling chain according to the inquiry request, returns the intelligent contract calling chain to the user terminal corresponding to the inquiry request, and if the verification of the second uplink request is not passed, returns a prompt indicating that the verification of the second uplink request fails, so that on the basis of ensuring the openness and transparency of the intelligent contract calling chain, the security of the intelligent contract calling chain is further ensured, and the user terminal having the authority of the inquiry request is ensured to inquire the intelligent contract calling chain, so that the intelligent contract calling chain ensures the openness and the transparency within the preset subject range. Steps S201 to S205 included in fig. 2 correspond to steps S101 to S105 in fig. 1, respectively, and are not described herein again.

In the intelligent contract calling process, data such as corresponding call stack information and the like are reported to a link tracking acquisition end server, and an intelligent contract calling chain is stored persistently to realize data reporting.
17) The block chain network identifies the intelligent contract 1 calling chain and the intelligent contract 2 calling chain together and performs block output; 18) the block chain network returns the uplink interface to the business end of the block chain platform; 19) the business end of the block chain platform returns the uplink interface to the business end of the block chain application; 20) and the block chain application business terminal returns the uplink interface to the terminal user terminal so as to realize uplink return of intelligent contract calling of the terminal user terminal.
With continued reference to FIG. 3, the process of querying the intelligent contract invocation chain includes the steps of:
(1) the request end (i.e. the terminal user end) sends a contract call chain query to the blockchain application provider end.
(2) And the block chain application provider side sends a contract calling chain query to the block chain platform provider side.
3) And the business end of the block chain platform checks the authority of the contract calling chain inquiry, and if the check is passed, the business end sends an inquiry request to a preset memory.
(4) And sending the contract calling chain query to a preset memory.
(5) The preset memory carries out link inquiry of the intelligent contract calling chain.
(6) And the preset memory inquires the intelligent contract call chain inquiry result and returns the intelligent contract call chain inquiry result to the business end of the block chain platform.
(7) And the block chain platform business end queries the intelligent contract call chain query result and returns the query result to the block chain application business end.
(8) And the block chain application business end inquires the intelligent contract calling chain inquiry result and returns the intelligent contract calling chain inquiry result to the request end so as to complete the inquiry of the intelligent contract calling chain.
Through the processes, the terminal user side can check the complete process of intelligent contract calling by clicking the corresponding page and triggering the calling chain inquiry interface after successfully triggering the uplink request on the terminal user side, so that the contract calling process and the result are transparent and public. The invention also solves the problems of the disclosure and the transparency of contract calling and management on the premise of realizing the safe trusteeship of the user key.
