Detailed Description

The following description of the embodiments of the present application is provided for illustrative purposes, and other advantages and capabilities of the present application will become apparent to those skilled in the art from the present disclosure.

In the following description, reference is made to the accompanying drawings that describe several embodiments of the application. It is to be understood that other embodiments may be utilized and that changes in the module or unit composition, electrical, and operation may be made without departing from the spirit and scope of the present disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Although the terms first, second, etc. may be used herein to describe various elements, information, or parameters in some instances, these elements or parameters should not be limited by these terms. These terms are only used to distinguish one element or parameter from another element or parameter. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the various described embodiments. Both the first and second elements are described as one element, but they are not the same element unless the context clearly dictates otherwise. Depending on context, for example, the word "if" as used herein may be interpreted as "at … …" or "at … …".

Also, as used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It will be further understood that the terms "comprises," "comprising," "includes" and/or "including," when used in this specification, specify the presence of stated features, steps, operations, elements, components, items, species, and/or groups, but do not preclude the presence, or addition of one or more other features, steps, operations, elements, components, species, and/or groups thereof. The terms "or" and/or "as used herein are to be construed as inclusive or meaning any one or any combination. Thus, "A, B or C" or "A, B and/or C" means "any of the following: a; b; c; a and B; a and C; b and C; A. b and C ". An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some way.

Those of ordinary skill in the art will appreciate that the various illustrative modules and method steps described in connection with the embodiments disclosed herein may be implemented as electronic hardware, or combinations of computer software and electronic hardware. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the implementation. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

Natural contracts, such as buying and selling contracts, leasing contracts, giving contracts, contracting contracts, and entrusting contracts of two or more parties are equivalent, and they require manual review, information transfer, and the like during execution, and the execution efficiency is low.

Although some block chain applications combined with contracts exist in the prior art, such as the ant chain of ant golden clothes, the block chain electronic contract application of "smart chain cloud sign" in the kyoto digital department, and the like, all do some work of electronic chain linking of contracts; however, these blockchain applications are only based on the consideration of reliable contract deposit, and the full text of the contract content is electronically stored, and do not involve the automatic execution logic related to the natural contract fulfillment, and the transaction actions of the contract signing party cannot be recorded on the blockchain, and it is impossible to trace back whether both parties perform.

Therefore, one of the inventive ideas of the present application is to provide the idea of converting natural contracts and pass-through into intelligent contracts in the embodiment, in view of the fact that the natural contracts and the intelligent contracts in the block chain technical field are communicated approximately on the contract characteristics, so as to utilize the automatic execution characteristics of the intelligent contracts to efficiently complete the executable parts in the natural contracts, and utilize the characteristic that the intelligent contracts are located in the block chain, so as to form credible records for tracing when subsequently resolving contract disputes.

The block chain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace retaining in the whole process, traceability, collective maintenance, openness and transparency and the like. The characteristics ensure the honesty and the transparency of the block chain and lay a foundation for creating trust for the block chain. Known block chain types are Public block chain (Public block chain), Private block chain (Private block chain) and alliance block chain (Consortium block chain).

The block chain is a distributed shared account book and a database, and each node in the block chain system generates blocks and updates under a mechanism of consensus confirmation. Each node may be implemented by a server, a server group, a tablet Computer, a mobile phone, a Personal Computer (PC), a notebook Computer, or other devices, or implemented by a distributed processing system with multiple configurations in these devices, and the nodes are connected through peer-to-peer network communication to transmit and receive information to and from each other.

An intelligent contract is a set of commitments (commitments) defined in digital form, comprising an agreement on which the contract participants can execute the commitments. In particular, smart contracts are a significant reason why blockchains are referred to as "decentralized," which allows for the execution of traceable, irreversible, and secure transactions without the need for third parties.

The intelligent contract contains all information about the transaction and only after the requirements are met will the resulting operation be performed, the code itself interpreting the relevant obligations of the parties.

In practice, an intelligent contract may be used for any transaction between two or more parties to contract, the code of which contains conditions that trigger the automatic execution of the contract. Smart contracts have been implemented in various blockchain networks, such as bitcoin networks and etherhouses, and other scenarios such as elections, supply chain optimization, e-commerce may also make efficient use of smart contracts.

Fig. 1 is a schematic flow chart showing an intelligent contract generating method in the embodiment of the present application.

In an embodiment, the intelligent contract generation method comprises the following steps:

step S101: and extracting contract contents in the natural contract.

In some examples, analyzing content in the natural contract includes at least: a basic information part, and an executable part.

The basic information part includes: terms related to basic information of each contracting party. In some examples, the basic information includes: identity information of each contracting party. For example, Paris A: a certain party and B party: b, or party a: enterprise A, party B: the company B may also add an identifier indicating its unique identity, such as a natural person's identification number, passport number, or the like, or a social credit code of the company, to the contract-signing party. Further, optionally, one or more of bank account information, address information, and the like may be added.

The executable portion includes: the contract content can be converted into terms that are automatically executed by the intelligent contract. For example, terms that can be directly and accurately automatically executed, such as time judgment, quantity judgment, data submission, request interaction, and the like, are involved, and in some practical examples, before a certain time point or within a certain time period, one or some parties need to submit a relevant result or an electronic certificate of the result, otherwise, a term of a certain monetary penalty is performed; or after the contractually agreed payment conditions are met, a certain party needs to pay within a certain period, and otherwise, certain amount of fine terms are carried out.

Optionally, the contract content further includes: a non-executable portion. The non-executable part refers to a clause which cannot be converted into a block chain intelligent contract code in the contract content and automatically judges execution, for example, if a design scheme is required to accord with xx style; and other descriptive content such as an explanation in a contract, etc.

Step S102: converting the contract content into an intelligent contract for blockchain for automatically executing the executable portion of the natural contract.

In this step, the contract content is converted into the intelligent contract, and the main part is the conversion of the executable part, so that the automatic execution of the executable part is realized by utilizing the automatic execution characteristic of the intelligent contract.

In some examples, the identity of contract partners that are relevant objects of the executable portion need to be determined in the smart contract; therefore, the basic information part can be converted into an intelligent contract for the block chain, and the intelligent contract specifically comprises the following steps: and configuring the on-chain address of the block chain corresponding to the identity of each contract signing party in the structural function of the intelligent contract corresponding to the identity information in the basic content.

In a blockchain, each party includes an intelligent contract whose identity is represented by an address on the chain of the blockchain.

In some examples, converting the executable portion to the smart contract includes: and forming execution logic corresponding to the executable part in the intelligent contract.

It should be noted that the execution logic formed by the intelligent contract is not directly obtained according to the executable contract logic of the natural contract; different from natural contracts, the functions realized by intelligent contracts cannot directly judge whether the achievements of contract signing parties meet the contract requirements or not. For example, it cannot be directly determined whether the submitted result meets the contract requirement, and whether the content of the electronic proof of the result is really proof and has a proof relationship with the result required by the contract.

The intelligent contracts are enabled to function in accordance with communications with (the on-chain address of the block chain of) each contract-contracting party to obtain the provision of electronic proof of fulfillment of the terms in the executable portion by one or more contract-contracting parties, and consensus confirmation of fulfillment by each contract-contracting party, etc., to determine whether the associated terms have indeed been fulfilled. For example, after a certain party or parties of the contract submit an action and a certain party or parties of the contract make a judgment and perform a reply action (confirm application or deny application) in any way according to requirements of terms related to the contract, automatically performing a preset action (including but not limited to paying contract fee, fines and updating the state of the intelligent contract) according to a related program in the intelligent contract.

In some examples, the information interaction between the intelligent contracting parties may include the following:

1. and submitting the action.

The submission action may be submitted by a result completing party of a certain contract signing party to the intelligent contract through its corresponding on-chain address of the block chain.

In some examples, the submission content of the submission action may include 2 types: submitting a result file to an intelligent contract; and submitting the modified intelligent contract content. Wherein the result document is used as a proof certificate of the result achieved by the contract signing party for fulfilling the contract terms. Optionally, the type and size of the result file may not be limited, and for example, the result file itself may also be a hash value of the file (for verification or finding the result file).

2. An action is applied.

In some examples, the application content of the application action may include one or more of: applying for confirming the submitted content of the submitted action; applying for a pause intelligent contract; applying for modifying the intelligent contract; and applying for terminating the intelligent contract.

The submission action may be made by a contract contracting party (including a work completing party) submitting to the intelligent contract through its corresponding on-chain address of the blockchain.

In an alternative implementation, the apply action may be a commit action that is accompanied by an originator of the commit action. For example, in the contract fulfillment process, one or several contract signing parties submit according to the time point or time period required by the specific terms of the contract, and upload the result, and simultaneously, apply for confirmation of the submitted content of the submission action along with the application action, that is, let other contract signing parties confirm through the intelligent contract.

Of course, in other examples, the application action may be presented without accompanying the submission action, and is not limited by the above examples.

3. And (6) returning to the action.

The reply action represents the confirmation of other contract signing parties to the content of the submission action or the application action initiated by the certain contract signing party, namely whether the result is approved or not; therefore, the recovery action comprises: an act of confirming or denying the contents of the act of submitting and applying for an act.

The mode of proposing the reply action is that a party of the contract submits to the intelligent contract through the address on the block chain of the party.

The execution logic of the intelligent contract judges the fulfillment condition of the corresponding contract clauses according to the contents of the actions.

For example, the execution logic of the intelligent contract comprises: according to the submitting action of at least one contract signing party on an electronic certificate representing the result formed by the contract signing party to fulfill the clause in the natural contract and the replying action of a result receiving party in other contract signing parties on the electronic certificate, judging whether the result meets the clause requirement to obtain a judgment result; and automatically executing corresponding preset actions according to the judgment result.

More specifically, the intelligent contract is informed when the at least one contract-signing party performs a submitting action of an electronic certificate indicating its achievement of fulfilling terms of the natural contract, and the at least one contract-signing party submits an application action for confirming the submission of the submitting action; other contract signing parties initiate a reply action to the result through interaction of respective addresses on the block chain and the intelligent contract, wherein if the result receiver of the other contract signing parties judges in any way and the submitted result meets the contract clause requirement, the result receiver performs a confirmed reply action to indicate that the result meets the contract requirement after the result receiver is identified; otherwise, if the result receiver judges that the result does not meet the requirement of the contract clause, a response action of denial is carried out; the intelligent contract determines whether to complete the contract according to the reply action of each result receiver.

In some examples, if the natural contract has a punishment term such as "if a needs to execute xxx before xx, otherwise, the penalty of xxx needs to be assumed", the execution logic of the intelligent contract may be implemented correspondingly.

The "before xx is time, a needs to execute xxx, otherwise, the fine of xxx needs to be assumed" may actually be correspondingly expressed in the execution logic of the smart contract as "if the action of submitting yyy certificate (i.e. representing the result of executing xxx action) exceeds the time limit, the smart contract automatically transfers the specified fine amount, and if the action is not overtime and the relevant party accepts yy certificate, the contract status (i.e. representing the status of executing the next step of the contract) is shifted backwards"; in some examples, the intelligent contracts are in effect a transfer of the amount of the fine, e.g., payment instructions may be formed directly to require the default party to pay the fine to the recipient's financial account, such as transferring some token of value (token) directly over the blockchain; alternatively, the voucher to be paid for the associated fine is formed and the fine funds are redeemed by some party by any means.

In some examples, at any time, a contract signing party can apply for suspending the intelligent contract, applying for terminating the intelligent contract and applying for modifying the intelligent contract (modifying the intelligent contract content along with the submission in the submitting action), and after each participant of the contract performs the confirmed application in the reply action, the intelligent contract changes correspondingly.

In some examples, the intelligent contracts may be activated to the blockchain by joint activation of the respective contract-contracting parties involved. Specifically, each contract signing party can electronically sign the block chain intelligent contract through the corresponding on-chain address of the block chain, so that the intelligent contract is activated, and then the intelligent contract can automatically execute the execution logic.

Fig. 2 is a schematic diagram showing a logic principle of an intelligent contract implemented by a natural contract in the embodiment of the present application.

In the present embodiment, it is assumed that contract contracting parties of the natural contract X have a party a and a party B, and have an on-chain address a and an on-chain address B in the blockchain, respectively.

The intelligent contract Y is located in a blockchain 201, and the blockchain 201 can be a public chain, a private chain or a alliance chain. The intelligent contract Y may include a plurality of modules, such as an interactive interface 202, a contract module 203, a payment module 204, a profile storage module 205, and the like. The natural contract X is converted into an intelligent contract Y, and a basic information part, an executable part and a non-executable part in the natural contract X are converted into a contract module 203 in the intelligent contract Y; the interactive interface 202 is used for communicating with the on-chain address A of the first party and the on-chain address B of the second party, for example, receiving the contents of the three actions; the data storage module 205 can be used to store, for example, results confirmed by both parties contracting, daily work records, etc., and store the results in the blockchain 201, so as to be used as a trusted certificate for tracing back when disputes occur in the future. The interactive interface 202 realizes the information interaction between the address A, B on the chain and the contract module 203 in the intelligent contract, and the calling authority of the interactive interface 202 can be configured in the construction function of the intelligent contract in advance; execution logic of the executable portion of the contract module 203 may perform the determining and pre-setting actions based on the information interaction with the linked address A, B, wherein the payment module 204 may be invoked to perform a funds transfer associated with the terms of the contract, such as payment of transaction funds, payment of fines, etc. Optionally, payment module 204 may implement payment by tokenization of a payment currency (e.g., bitcoin, firecoin, etc.), or by final clearing of a transaction currency.

In addition to transactions such as bitcoin or other on-chain assets, the smart contracts can also complete transactions in a universal currency.

Specifically, when the achievement of the contract purpose of the natural contract requires on-line or off-line monetary payment between contract issuers, the intelligent contract generating method further includes: generating payment credentials approved by a payment authority at the smart contract by a payer; wherein the payment credentials are for acquisition by a payer to obtain a corresponding payment currency from the payment authority in an online or offline manner; the payment mechanism includes: a bank or a third party payment authority.

For example, the receiver a (payer) in the contract contractor generates an electronic certificate of 100 ten thousand yuan of RMB required to be paid for purchase in the intelligent contract, when the sender B (payee) in the contract contractor completes the contract and sends the goods to the receiver a, the submitted certificate is approved by the intelligent contract, the electronic certificate can be traded to the sender B, the sender B can obtain the electronic certificate, and obtain 100 ten thousand yuan of goods from the internet bank or off-line bank. In an alternative example, the electronic certificate may be, for example, the characteristic information of an electronic check approved by a certain bank, etc., and the certain bank may verify the authenticity through a specific verification algorithm to determine whether the corresponding money payment can be completed.

In some examples, events, records, etc. occurring during the execution logic of the contract module 203 may generate a blockchain 201 event log stored in the blockchain 201, and may also be used as a trusted certificate for tracing back when a dispute occurs in the future.

In S301, the smart contract is signed. The intelligent contracts are stored and run on a blockchain. For example, in a blockchain system, the nodes of each contracting subscriber deploy the code of the intelligent contract, and the intelligent contract is activated through consensus.

In S302, information interaction is performed between each contract signing party and the intelligent contract according to needs. For example, in the foregoing embodiment, the communication of information interaction is performed between the on-chain address of the contract contracting party and the interaction interface of the intelligent contract. The diagram is simply expressed as "normal flow communication".

When some party finds that the intelligent contract content needs to be adjusted, such as the result form, the result submission time, the payment time and the like, the process proceeds to S303.

In S303, the contract parties perform communication negotiation, and if agreement is reached, the intelligent contract content to be modified is determined, and the process proceeds to S304.

In S304, a certain contract signing party determined by negotiation submits an intelligent contract modification application and modification content, namely the contract modification application in the figure is submitted;

in S305, after the contract modification application of S304 is confirmed by the electronic signatures of each party, the modified intelligent contract is activated, and each contract signing party determines to execute the contract according to the modified intelligent contract due to the version upgrade of the intelligent contract; and then returning to the state of S302, and communicating the parties according to the needs.

In S303, if the contract signing parties do not agree with the intelligent contract modification content negotiation, processing according to an agreed dispute handling manner, such as arbitration litigation; and proceeds to S306.

In S306, the intelligent contract status becomes suspended due to disputes between the contract-contracting parties.

If agreement is reached after S306, the adjustment returns to S304; if the two values do not match, the process proceeds to S307.

In S307, the smart contract state changes to terminated.

If each contracting party has no problem with the intelligent contract in S302, and the process proceeds to S308,

in S308, when a contract signing party submits the result or the electronic certification of the result to the intelligent contract through a submitting action, and an application action is accompanied to apply for confirming the submitted content; the result submitted to the intelligent contract agreement by a certain contract signing party;

in S309, each outcome recipient receives the application, confirms that the outcome satisfies the requirement of contract agreement, and submits the information of confirmed outcome to the intelligent contract through the reply action, which is shown as "the submitted outcome is confirmed" in the figure.

If all the achievement receivers confirm that the contract is completed, the intelligent contract can generate contract completion certification information, and the contract completion certification information is collected and submitted to a payment system for payment and settlement; of course, this payment method is merely an example, and in other embodiments, the payment may be completed in real time each time the payment needs to be completed, which is not limited to this; and then may proceed to S310.

In S310, when the payment and settlement are completed, the smart contract execution is ended.

If in S308, a certain contract signing party considers that the result does not meet the contract agreement, the information of response denial is submitted to the intelligent contract through a response action; i.e., proceeds to S311.

In S311, the submission outcome is denied.

In this case, if the rejection does not affect the execution of the smart contract, return S302 continues the normal running of the smart contract. For example, the result is rejected to be submitted in advance, and the result can be submitted again before the deadline, so that the contract is not influenced; optionally, if there is a relevant penalty clause in the contract, the execution logic of the intelligent contract triggers execution of a corresponding penalty measure, such as a fine, and the record can be automatically made to be calculated at the time of payment settlement later.

If the denial affects execution of the intelligent contract, e.g., a deadline for delivery of the outcome has passed, etc.; the state of the intelligent contract can be changed into pause, and S303 is entered for communication negotiation among contract signing parties; if there is a relevant penalty clause in the contract, the execution logic of the intelligent contract triggers the execution of a corresponding penalty measure, such as a fine, which can be automatically recorded to be calculated at the time of payment settlement later.

As another specific example, an implementation manner of the above embodiment in an actual scene is exemplarily described.

For example, in a project design phase in the engineering construction field, a project developer (a) enters into a project design contract with a designer (a). The main contents of the contract comprise the following contents:

first, contract main body

Prescription A: a project developer X, funding account B-X;

b, prescription B: a designer Y, funding accounts B-Y;

two, stage

The contract stipulates that the project is divided into 2 stages:

the first stage, party A provides initial data before date D, and party B designs; the first stage cycle begins after the initial data is submitted, and does not exceed 30 working days; the first stage achievement requires the second party to submit the design file in the middle period, and the design depth meets the cost estimation requirement.

In the second stage, the second party carries out deepened design from the time that the second party submits the design file in the middle period and obtains the confirmation of the first party. The period of the first stage does not exceed 60 working days; the second stage of achievement requires the second party to submit the final design file, and the design content and depth meet the requirements of obtaining the inspection qualified books of relevant supervision departments.

Third, confirm and fund payment

After the other party submits the file or the request, any party needs to reply confirmation or rejection within 5 working days, otherwise, the confirmation is defaulted;

paying the party B m1 Yuan within 10 working days after the party A receives and confirms the first-stage result submitted by the party B;

the party A pays the party B m2 yuan within 20 working days after receiving and confirming the second-stage result submitted by the party B;

penalty of default

Any party does not submit relevant documents and materials according to the contract requirement, and the fine is N yuan every working day later (less than one according to one).

Fifth, other clauses

Design style, quality requirements, file format requirements, etc.

On the basis of signing a contract, the two parties can be supervised and urged to perform by adopting the method shown in the patent. The specific method comprises the following steps:

1. both parties apply for the on-chain address of the block chain, and any party converts the contract into an intelligent contract A.

2. The basic information part in the intelligent contract A comprises: first, contract main body and the on-chain address corresponding to both parties.

3. The executable part in the intelligent contract A comprises: two, stage (but not including design depth and design content requirements), three, medium capital payments, and four, medium default penalties.

4. The non-executable part in the intelligent contract A comprises: second, design depth and design content requirements in the stage, and fifth, other requirements.

5. The specific steps of converting into the intelligent contract A are as follows: the constructor in the intelligent contract needs the on-chain addresses of the two parties A and B in the basic information part to define the identity; the executable part of the intelligent contract is divided into two stages according to the contract description, the first stage automatically enters the second stage after being completed, the two stages comprise executable terms which are three requirements of 'a party needs to submit a certificate of initial data before D days, a penalty of N yuan is given out for one day, a party B needs to submit a design file in the first stage within 30 days, a penalty of N yuan is given out for one day, a party B needs to submit a final design file in the second stage within 60 days', and a contract III, and all the three requirements are converted into intelligent contract codes; and storing the words of the non-executable part in the 4. in the intelligent contract A.

6. The completed intelligent contract a is uploaded into the blockchain by any party. The related party of the intelligent contract A is the chain address of the first and second parties, and the account for paying and receiving funds is the chain address of the first and second parties.

7. The two parties A and B carry out signature confirmation on the intelligent contract A through respective linked addresses, the intelligent contract in the direction A transfers asset vouchers of m1+ m2 elements, meanwhile, the two parties A and B transfer a plurality of fine guaranties to the intelligent contract, and the intelligent contract A starts to run.

8. Party A fails to submit the original material before date D, but instead performs the act of submitting on day D +2 (2 days later) and synchronously submits the application (the application acknowledges the submission).

9. And the second party receives the file on the D +2 day, and after judging that the file meets the requirement, the second party performs a reply action (application confirmation), and the intelligent contract judges that the first party violates and automatically transfers the 2N-element assets to the address account of the second party.

10. The second party starts to design, and performs a submission action (submitting the result file to the intelligent contract) on the 31 st day (1 day later) after the first stage starts, wherein the submitted action is the hash value of the design file (the first party can extract the design file from a certain storage system by the hash value). And simultaneously carrying out the submission action, the party B synchronously submits the application action (the application confirms the submitted content).

11. The first party receives the hash value submitted by the second party and extracts the design file, the first party considers that the first party does not meet the requirements on the design style in the fifth and other terms in the contract after judgment, and carries out a reply action (a rejection application) on the 35 th day after the first stage, and simultaneously, the contract judges that the second party violates and automatically transfers the N-element assets to the address account of the first party.

12. After the two parties communicate in various modes, the agreement is reached on the 40 th day after the first stage, and the agreement is agreed: and starting intelligent contract suspension at the 35 th day after the first stage, continuing at the 45 th day after the first stage, resubmitting the intermediate-term result by the second party before the 45 th day after the first stage, and submitting related applications by the second party and confirming the related applications by the first party.

13. And the second party performs the submitting action again at the 45 th day after the first stage (submits the result file to the intelligent contract), the submitted content is the hash value of the design file, and the application action is synchronously submitted (the application confirms the submitted content).

14. And the first party meets the requirements after judgment, performs a reply action (confirmation application) on the 50 th day after the first stage, and automatically transfers the m1 yuan assets from the contract to the account of the second party after the contract judges that the first stage is finished.

15. The second party carries out the submitting action and the application action in time at the second stage, the submitted content is the final design file, and then the first party also carries out the reply action (confirmation application). The contract judges that the second phase is over and transfers the m2 meta-asset to the second party address account. And simultaneously, after all the stages are judged to be finished by the contract, the residual deposit is returned to the address accounts of the first and second parties respectively.

Through the application of the method, common and possible actions which are rarely followed by duty, such as the first party delaying to submit initial data, the second party delaying to submit results, not paying according to contract requirements and the like, can be limited and controlled in the original natural contract execution, and the overall contract spirit of the society can be promoted along with the continuous popularization of the method.

And for each contract signing party of the contract, the time node of file submission and the time node of payment required in the contract can be well controlled, and related terms can be implemented, so that the overall work of each party is facilitated, and the execution efficiency of the contract is improved.
