Background
The intelligent contract is to embed the contract terms into the software and hardware, and to make the contract execute through the agreement and the user interface. In recent years, the rise of the block chain technology creates conditions for intelligent contracts, and the intelligent contracts can support programmable contracts and have the characteristics of decentralization, non-tampering, transparent and traceable processes and the like. The trusted environment on the blockchain has helped the explosion of intelligent contracts. The existing intelligent contract of the block chain is made by the participation of multiple users, the intelligent contract is stored in the block chain network, and when the simple description condition written in advance is satisfied, the program automatically executes the contract. The described intelligent contract execution method is too simple in judgment logic and not suitable for requirements on intelligent contract execution in specific scenes, on one hand, only partial merchants meeting conditions in executed contracts cannot be selected in a self-defined mode according to user preference, on the other hand, network structures formed in merchant cooperation or transaction processes are not considered at all, network constraints of the network structures can guarantee close cooperation among the merchants, and effectiveness and safety of intelligent contract execution can be greatly promoted.
The existing intelligent contract construction and execution rough flow comprises the following steps: multiple users participate in making intelligent contracts together; contracts are diffused through the P2P network and stored in block chains; the blockchain determines when and whether the intelligent contract is executed based on the contract description. For example, if a description of "transaction amount greater than 100 ten thousand" is added to the smart contract, the contract will automatically execute when the transaction amount is greater than 100 ten thousand. The method for executing the contract based on the simple description is not suitable for the complex execution requirement of the intelligent contract under some specific scenes, and the execution condition of the contract can not be measured in multiple dimensions, so that the application of the intelligent contract is greatly limited, and the requirement of a user is difficult to meet.

fig. 1 shows an implementation flow of an intelligent contract execution method provided in an embodiment of the present invention, and for convenience of description, only parts related to the embodiment of the present invention are shown, which are detailed as follows:
in step S101, an intelligent contract execution request input by a user is received, where the execution request includes a search keyword.
The embodiment of the invention is suitable for a network intelligent contract system, so as to conveniently measure the contract execution conditions through multiple dimensions and realize the purpose of automatically executing the intelligent contract. In the embodiment of the invention, before searching for the merchants capable of executing the intelligent contracts, the user firstly sets a group of search keywords for the intelligent contracts as search keywords for continuous search to screen the merchants meeting the custom contract execution conditions, wherein the search keywords set by the user are contained in the intelligent contract execution request input by the user. For example, the user first enters a search keyword in an input box of the search keyword, and then triggers an intelligent contract execution request.
In step S102, a tree index established for the associated merchant in the intelligent contract in advance is obtained, and a form corresponding to the search keyword is generated in the inverted list of the tree index.
In the embodiment of the invention, all the merchants in the merchant network preset by the user are covered in the tree index, wherein, on one hand, network constraints exist among the merchants in the merchant network, and frequent cooperation or transaction can be ensured among the merchants through the network constraints, so that the connections among the merchants are tighter and have practical and practical significance, and on the other hand, the merchants in the merchant network are associated with the intelligent contract, namely the merchants are the merchants signed with the intelligent contract, so that the accuracy, the effectiveness and the safety of executing the contract are improved. After receiving an intelligent contract execution request input by a user, firstly acquiring a search keyword corresponding to the execution request, then acquiring a tree index established for a related merchant in the intelligent contract in advance, and generating a form corresponding to the search keyword in an inverted list of the tree index.
In step S103, it is detected whether the generated form is empty, and when the generated form is not empty, all paths of the tree index are traversed, merchants covering the search keyword are searched in the traversed nodes, and the searched merchants covering the search keyword are added to the contract execution merchant list.
In the embodiment of the invention, whether a form corresponding to the search keyword in the inverted list of the tree index is empty is firstly detected, namely whether merchants meeting contract execution conditions corresponding to the search keyword exist in the merchants included in the tree index is determined according to the inverted list. If the form corresponding to the search keyword in the inverted list of the tree index is not empty, it indicates that there is a merchant satisfying the contract execution condition corresponding to the search keyword in the merchants included in the tree index, that is, the merchant capable of executing the intelligent contract is searched according to the tree index, and at this moment, the merchant capable of executing the intelligent contract is searched according to the tree index. If the form corresponding to the search keyword in the inverted list of the tree index is empty, it indicates that no merchant satisfying the contract execution condition corresponding to the search keyword exists in merchants included in the tree index, and therefore, no intelligent contract is executed for any merchant temporarily.
Preferably, in the process of traversing all paths of the tree index, when a merchant covering the search key word is searched in the traversed nodes, a branch path of the tree index is selected first, then the search is performed along the path from the root node to the non-root node, if a certain node in the branch path does not satisfy the search condition along the path, the search of the branch path is ended, the searched merchant covering the search key word is added into the contract execution merchant list, and then all branch paths of the tree index are traversed, so that all merchants meeting the contract execution condition included in the tree index are added into the contract execution merchant list, thereby improving the rate of merchant search and the effect of search.
In step S104, the intelligent contracts associated with the search keywords are executed for the merchants in the contract execution merchant list.
In the embodiment of the invention, the intelligent contract can provide contracts such as transaction tax return preference for merchants meeting the conditions for governments, and the association grades the merchants meeting the conditions, and the merchants in the contract execution merchant list are mutually associated and meet the search keyword constraint set by the user, namely, the merchants not only cover all search keywords, but also have cooperation with each other. After obtaining the contract execution merchant list, executing the intelligent contracts associated with the search keywords for the merchants in the contract execution merchant list, thereby improving the effectiveness and the safety of executing the intelligent contracts while improving the execution efficiency of the intelligent contracts.
In the embodiment of the invention, after the user gives the execution condition (such as a group of search keywords), merchants covering all the search keywords are continuously searched in the merchant network with business association relation, and then corresponding contracts are executed for the searched merchants, so that the business association relation among the merchants and the conditions of the merchants are combined, the intelligent contract execution efficiency is improved, and meanwhile, the effectiveness and the safety of executing the intelligent contracts are improved.
Example two:
fig. 2 shows an implementation flow of the intelligent contract execution method provided by the second embodiment of the present invention, and for convenience of description, only the parts related to the second embodiment of the present invention are shown, which are detailed as follows:
in step S201, a merchant network composed of associated merchants in the intelligent contract is obtained, and a core value of the merchant in the merchant network is calculated.
The embodiment of the invention is suitable for a network intelligent contract system, so as to conveniently measure the contract execution conditions through multiple dimensions and realize the purpose of automatically executing the intelligent contract. In the embodiment of the invention, a merchant network consisting of merchants signed with contracts is obtained firstly, and the core values of the merchants signed with the contracts are calculated by using a k-core structure decomposition method.
In step S202, a tree index corresponding to the merchant network is established according to the core value.
In the embodiment of the present invention, merchants in the root node of the layer 1 of the tree-type index can form a core structure of 0, merchants under each node of the layer 2 can form a core structure of 1, and so on, a merchant group under each node in the tree is a part of a merchant group formed under a parent node thereof, and nodes (including leaf nodes) through which a path from each leaf node to the root node passes in the tree form a connected part in the whole merchant transaction network, that is, each merchant under the part has at least one path to another merchant, and each merchant only appears in one tree node. The information in the root node includes an independent merchant (i.e., a merchant which does not cooperate with other merchants), a k value of a k core structure formed by a customer group under the node, an inverted list established according to all merchants under the whole network, and child node information, the information of a non-root node is stored in a node information list, and the node information list includes the merchant forming the k core structure, the k value of the k core structure formed by the customer group under the node, location information, child node information, and parent node information corresponding to the merchant lacking compared with its parent node in the inverted list.
Preferably, when the tree index corresponding to the merchant network is established according to the core value of the merchant, a root node of the tree index is established first, the merchant with the core value of zero is set as the merchant in the root node of the tree index, an inverted list corresponding to the root node is established according to the type of the merchant in the merchant network, then the merchant with the core value of nonzero is divided into different remaining merchant sets according to the relationship of the merchant with the core value of nonzero in the merchant network, finally all the remaining merchant sets are traversed, a corresponding non-root node is established according to the core value of the merchant in the remaining merchant sets, and the merchant in the remaining merchant sets are respectively set as the merchant in the corresponding non-root node of the tree index according to the core value, so that the merchant in the tree index meets network constraints, the dimensionality of a search condition is reduced, and the rate of searching for merchants is improved.
In step S203, an intelligent contract execution request input by a user is received, where the execution request includes a search keyword.
In the embodiment of the invention, before searching for the merchants capable of executing the intelligent contracts, the user firstly sets a group of search keywords for the intelligent contracts as search keywords for continuous search to screen the merchants meeting the custom contract execution conditions, wherein the search keywords set by the user are contained in the intelligent contract execution request input by the user. For example, the user first enters a search keyword in an input box of the search keyword, and then triggers an intelligent contract execution request.
In step S204, a tree index that is established in advance for the associated merchant in the intelligent contract is obtained, and a form corresponding to the search keyword is generated in the inverted table of the tree index.
In the embodiment of the invention, all the merchants in the merchant network preset by the user are covered in the tree index, wherein, on one hand, network constraints exist among the merchants in the merchant network, and frequent cooperation or transaction can be ensured among the merchants through the network constraints, so that the connections among the merchants are tighter and have practical and practical significance, and on the other hand, the merchants in the merchant network are associated with the intelligent contract, namely the merchants are the merchants signed with the intelligent contract, so that the accuracy, the effectiveness and the safety of executing the contract are improved. After receiving an intelligent contract execution request input by a user, firstly acquiring a search keyword corresponding to the execution request, then acquiring a tree index established for a related merchant in the intelligent contract in advance, and generating a form corresponding to the search keyword in an inverted list of the tree index.
In step S205, it is detected whether the generated form is empty, and when the generated form is not empty, one child node is selected from the child nodes of the root node, and the selected child node is set as the current node.
In the embodiment of the invention, whether a form corresponding to the search keyword in the inverted list of the tree index is empty is firstly detected, namely whether merchants meeting contract execution conditions corresponding to the search keyword exist in the merchants included in the tree index is determined according to the inverted list. If the form corresponding to the search keyword in the inverted list of the tree index is not empty, it indicates that there is a merchant satisfying the contract execution condition corresponding to the search keyword in the merchants included in the tree index, that is, the merchant capable of executing the intelligent contract can be searched according to the tree index, at this time, one child node is selected from the child nodes of the root node, and the selected child node is set as the current node, so as to perform merchant search. If the form corresponding to the search keyword in the inverted list of the tree index is empty, it indicates that no merchant meeting the contract execution condition corresponding to the search keyword exists in merchants included in the tree index, and no intelligent contract is executed for any merchant temporarily.
In step S206, the inverted list of the root node is checked according to the node information table of the current node, and it is determined whether the merchant group of the current node covers the search keyword input by the user, and the merchants in the merchant group form a k-core structure, if yes, step S208 is executed, otherwise, step S207 is executed.
In step S207, when the merchant group of the current node does not cover the search keyword input by the user, the sibling node of the current node is set as the current node.
In step S208, when the merchant group of the current node covers the search keyword input by the user, it is determined whether the current node is a leaf node, if yes, step S209 is performed, otherwise, step S210 is performed.
In the embodiment of the invention, the inverted list of the root node is checked according to the node information table of the current node, whether the merchant group of the current node covers the search keyword input by the user is confirmed, namely, the information of the merchants which are lacked in the inverted list compared with the parent node in the current node is checked, only the lacked merchants are concerned whether in the list of the given search keyword, the lacked merchants are in the list of the given search keyword, the merchants are excluded from the corresponding list, the list information of the given search keyword of the user is updated, if the list information is updated and all the search keywords cannot be covered, the merchant group of the current node does not cover the search keyword input by the user, at the moment, the brother node of the current node is set as the current node to search the next branch path, if the list information is updated and all the search keywords can be covered, the merchant group of the current node covers the search keyword input by the user is explained, at this time, whether the current node is a leaf node is determined to determine whether the merchant in the current node merchant group is added into the contract execution merchant list, so that the searching speed and the searching effect are improved.
In step S209, when the current node is a leaf node, the merchants in the current node merchant group are added to the contract execution merchant list, and the sibling node of the current node is set as the current node.
In step S210, when the current node is not a leaf node, a merchant confirmation operation is performed on the current node to confirm whether merchants in the current node merchant group are added to the contract execution merchant list, and a sibling node of the current node is set as the current node.
In the embodiment of the invention, if the current node is a leaf node, the merchants in the current node merchant group are added into the contract execution merchant list, then the brother node of the current node is set as the current node to search the next branch path, if the current node is not the leaf node, the merchant confirmation operation is firstly carried out on the current node to confirm whether the merchants in the current node merchant group are added into the contract execution merchant list, and then the brother node of the current node is set as the current node to search the next branch path.
Preferably, when the merchant confirmation operation is performed on the current node, firstly, the inverted list of the root node is checked according to the node information table of the child node of the current node, then, whether the merchant group of the child node of the current node covers the search keyword input by the user is confirmed, if all the child nodes of the current node do not cover the search keyword input by the user, the merchants in the merchant group of the current node are obtained, the obtained merchants are added into the contract execution merchant list, if one or more child nodes of the current node cover the search keyword input by the user, whether the one or more child nodes are leaf nodes is confirmed, if the one or more child nodes are leaf nodes, the merchants in the merchant group of the one or more child nodes are added into the contract execution merchant list, and if the one or more child nodes are not leaf nodes, the merchant confirmation operation is further performed on the one or more child nodes, and determining whether merchants in the one or more sub-node merchant groups are added into a contract execution merchant list or not, and ending merchant determination operation when the sub-nodes covering the search keywords are leaf nodes or all the sub-nodes do not cover the search keywords, thereby improving the search rate and the search effect.
In step S211, the intelligent contracts associated with the search keywords are executed for the merchants in the contract execution merchant list.
In the embodiment of the invention, the intelligent contract can provide contracts such as transaction tax return preference for merchants meeting the conditions for governments, and the association grades the merchants meeting the conditions, and the merchants in the contract execution merchant list are mutually associated and meet the search keyword constraint set by the user, namely, the merchants not only cover all search keywords, but also have cooperation with each other.
