Fig. 1 shows a schematic flow diagram of a block chain-based overdue contract processing method in an embodiment of the present disclosure. The embodiment can be applied to an electronic device, and as shown in fig. 1, the method for processing an overdue contract based on a block chain of the embodiment includes the following steps:
step S110, in response to the signing terminal detecting the overdue unsigned target contract, obtaining the signing record of the target contract from the block chain.
The signing terminal is qualified for processing the target contract, and a signing party of the target contract can sign through the signing terminal. The target contract may be an electronic contract, or the like. The contract records include processing events for the target contract, and the contract records for the target contract may be stored in a blockchain.
In one implementation, after a signing terminal initiates a signing process for a target contract, a signing party of the target contract needs to sign the target contract within a signing time specified by the signing terminal, the signing for the target contract is completed, and when the signing party does not sign the target contract beyond the specified signing time, an overdue unsigned target contract is generated. For example, the contracted duration specified by the contracted terminal may be 1 hour, and when the contracted terminal does not detect that the contracted party signed the target contract after transmitting the target contract to the contracted party for 1 hour, the target contract is determined to be an overdue unsigned target contract.
The Block Chain (Block Chain) is a Chain data structure which combines data blocks in a sequential connection mode according to a time sequence and is a distributed book which is cryptographically used for ensuring that the data cannot be tampered and forged.
And step S120, acquiring the number of times of overdue unsigned target contracts according to the signing records of the target contracts.
The signing record can include the number of times of overtime unsigned, the record of the overtime unsigned, and the like of the target contract, and the record of the overtime unsigned includes: a contractor who expires without signing the target contract, a time at which an expired without signing the target contract is detected, a signed contractor, etc.
In one implementation, when the signing terminal detects an overdue unsigned target contract, the signing terminal generates an overdue unsigned record of the target contract, where the overdue unsigned record includes the contracting party that overdue unsigned the target contract, the time at which the overdue unsigned target contract was detected, and the signed contracting party. And the signing terminal acquires the signing record of the target contract from the block chain, updates the overdue unsigned record of the target contract into the signing record, and updates the number of overdue unsigned times in the signing record, namely adds 1 to the number of overdue unsigned times.
Step S130, in response to the number of times of overdue unsigned target contracts being less than or equal to the first preset number of times, the signing terminal sends a contract signing request aiming at the target contract to the signing party of the overdue unsigned target contract, so that the signing party of the overdue unsigned target contract signs the target contract.
The signing terminal may be preset with a first preset number of times, which may be set according to an actual requirement, for example, the first preset number of times may be 1 time. The contract signing request may include the target contract.
In one implementation mode, when the signing terminal determines that the number of overdue unsigned times of the target contract is less than or equal to a first preset number of times, the signing terminal sends a contract signing request aiming at the target contract to a client of a signing party which overdue unsigned the target contract, wherein the client of the signing party is in communication connection with the signing terminal. A contractor that expires without signing the target contract may sign the target contract with its client.
In the embodiment of the present disclosure, step S130 and step S140 are not in sequence, and after the signing terminal executes step S130, when the signing party that overdue and unsigned the target contract signs the target contract, the signing terminal may execute a subsequent signing process, for example, when the signing party that overdue and unsigned the target contract is the signing party with the last signature of the target contract, the signing is completed on the target contract, and when the signing party that overdue and unsigned the target contract is not the signing party with the last signature, the signing is performed on the target contract by sending the target contract to the next signing party. And when the signatory of the overdue unsigned target contract does not sign the target contract, updating the number of overdue unsigned times in the signing record, and then determining to execute the step S130 or the step S140 according to the updated number of overdue unsigned times.
Step S140, in response to that the number of times of overdue unsigned of the target contract is greater than the first preset number of times and less than or equal to the second preset number of times, the signing terminal sends a re-signing request to the signed signing party of the target contract.
Wherein the re-signing request comprises the target contract. The second preset number of times may be set according to an actual situation, where the second preset number of times is greater than the first preset number of times, for example, the second preset number of times may be 2 times.
In one implementation, the contract record may also include the contractors signed for the target contract. When the signing terminal determines that the number of the overdue unsigned times of the target contract is larger than a first preset number of times and smaller than or equal to a second preset number of times, the signing terminal determines a signing party signed on the target contract according to the signing record of the target contract and sends a re-signing request to a client side of the signing party signed on the target contract.
Step S150, in response to the signing terminal receiving the determined re-signing instruction sent by the signed signing party of the target contract for the re-signing request, the signing terminal sends a contract signing request for the target contract to the signing party which has not signed the target contract for an overdue period.
When the signed signing party determines that a target contract is signed again, the client of the signed signing party sends a determining and re-signing instruction aiming at the re-signing request to a signing terminal;
in one implementation mode, when a signing terminal receives a re-signing refusing instruction sent by a signed signing party in a target contract aiming at a re-signing request, the signing terminal sets a preset watermark on the target contract so as to invalidate the target contract; the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract; the voided contract is uploaded to the blockchain storage.
In the embodiment of the disclosure, different processing modes are performed on the overdue unsigned target contract according to the actual condition of the overdue unsigned target contract, so that the effect of re-signing only for the signatory who does not sign the target contract is realized, the process of repeatedly signing the overdue unsigned target contract by the signed signatory is avoided, and the use experience of a user is improved. In addition, in the embodiment of the disclosure, when the number of times of overdue unsigned target contracts is less than or equal to the first preset number of times, without user operation, the signing terminal directly sends a contract signing request for the target contract to the signing party of the overdue unsigned target contract, which not only avoids that the target contract is not signed due to forgetting of the user, but also directly invalidates the target contract which is not signed due to overdue unsigned target contract, so that the user needs to initiate a signing flow again when signing the target contract, thereby improving the signing efficiency of the target contract, and further improving the use experience of the user without user operation.
In an optional embodiment, as shown in fig. 2, the method for processing an overdue contract based on a blockchain according to an embodiment of the present disclosure further includes the following steps:
and step S210, in response to the fact that the number of times of the target contract which is not signed for a long time is larger than a second preset number of times, the signing terminal sets a preset watermark on the target contract so as to invalidate the target contract.
The style and content of the preset watermark may be preset at the signing terminal, for example, the content of the preset watermark may be "obsolete", and the style may include: transparency of "voiding", font size, location of display in the target contract, etc. The signing terminal can add a preset watermark in the target contract through watermark loading software or program, and the target contract is invalidated.
And step S220, the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract.
Wherein a target contract with a private key generated signature and a preset watermark may be referred to as a revocation contract. The public-private key pair comprises a public key and a private key, the public key in the public-private key pair is used for verifying a signature generated by the private key in the public-private key pair, and the private key in the public-private key pair is used for signing data or information and the like. The signing terminal may generate the public-private key pair using a public SM2 algorithm, a symmetric encryption algorithm, or an asymmetric encryption algorithm.
In one implementation mode, when the signing terminal determines that the number of overdue unsigned times of the target contract is smaller than or equal to a first preset number, the signing terminal sends a contract signing request aiming at the target contract to a signing party which overdue unsigned the target contract, and when the signing party which overdue unsigned the target contract does not sign the target contract within the specified signing time, the number of the overdue unsigned times in the signing record is updated.
The subscribing terminal executes step S120, and when the subscribing terminal determines, according to the updated number of overdue unsigned times obtained in step S120, that the updated number of overdue unsigned times satisfies the condition of the number of overdue unsigned times in step S130 (less than or equal to a first preset number), the subscribing terminal executes the operation of step S130, when the updated number of overdue unsigned times satisfies the condition of the number of overdue unsigned times in step S140 (greater than the first preset number and less than or equal to a second preset number), the subscribing terminal executes the operation of step S140, and when the updated number of overdue unsigned times satisfies the condition of the number of overdue unsigned times in step S210 (greater than the second preset number), the subscribing terminal executes the operation of step S210.
In step S230, the invalidation contract is uploaded to the blockchain storage.
Wherein the contracting terminal may store the revocation contract in the blockchain. The signing terminal can also send a target contract signing failure message and a memory address of the voiding contract to all signing parties of the target contract.
In an alternative embodiment, as shown in fig. 3, step S110 of the embodiment of the present disclosure may further include the following steps:
step S111, in response to the signing terminal detecting the overdue unsigned target contract, determining whether the signature of the signing party of the target contract is included in the target contract.
When the signing terminal detects the target contract which is not signed for a long time, the signing terminal determines whether the signature of the signing party is included in the target contract or not.
In one implementation, whether signed contractors are included in the contract record of the target contract may be checked, and when signed contractors are included in the contract record of the target contract, the signature of the contractors of the target contract may be determined to be included in the target contract, e.g., when 1 signed contractor is included in the contract record of the target contract, then one of the contractors of the target contract is represented to sign the target contract.
In one implementation, after a contractor signs a target contract, the signing terminal records the signed contractor in a signature record.
Step S112, in response to the signature of at least one contractor including the target contract in the target contract, obtains a contract signing record of the target contract from the blockchain.
When the signing terminal determines that the target contract comprises the signature of at least one signing party of the target contract, the signing terminal acquires the signing record of the target contract from the block chain.
In an optional embodiment, the method for processing an overdue contract based on a blockchain according to the embodiment of the present disclosure further includes: and in response to the target contract not comprising the signature of the contractor of the target contract, the signing terminal sets a preset watermark on the target contract to invalidate the target contract.
When the signing terminal detects the target contract which is not signed for a period of time, the signing terminal determines whether the signature of the signing party is included in the target contract, and when the signing terminal determines that the signed signing party is not included in the signing record of the target contract, the signing terminal can determine that the target contract does not include the signature of the signing party of the target contract.
In one implementation mode, when the target contract does not include the signature of the signing party of the target contract, the signing terminal sets a preset watermark on the target contract so as to invalidate the target contract; the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract; a voiding contract is uploaded to the blockchain storage.
In the embodiment of the disclosure, when it is determined that the target contract has no signature of the contracting party and the target contract has expired without signature, it indicates that all the contracting parties of the target contract do not sign the target contract, and at this time, the target contract is set as void without user operation, and the contracting terminal automatically voids the target contract, thereby simplifying the contracting process and improving the user experience.
The following is an application embodiment of the block chain-based overdue contract processing method in the embodiment of the present disclosure, where a contracted terminal is provided with a specified contracted duration, and taking a target contract having two contracting parties as an example, the contracting parties of the target contract are a contracting party a and a contracting party B, respectively, as shown in fig. 4, a contracted flow of the target contract at the contracted terminal includes the following steps:
step 1, a signing terminal sends a first contract signing request (contract signing request) to a signing party A, wherein the first contract signing request comprises a target contract;
step 2, detecting whether a signing party A signs a target contract within a specified signing time, when the signing party A does not sign the target contract within the specified signing time, detecting the target contract which is not signed for an overdue by a signing terminal, executing the step 3 by the signing terminal, and when the signing party A signs the target contract within the specified signing time, executing the step 6 by the signing terminal;
step 3, the signing terminal determines whether the target contract which is not signed for a long time comprises the signature of the signing party of the target contract, at the moment, the signing party A signs the target contract firstly, so the target contract does not comprise the signatures of the signing party A and the signing party B, and the signing terminal executes the step 4;
step 4, the signing terminal sets a preset watermark on the target contract to invalidate the target contract;
step 5, the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract; uploading the invalidation contract to the blockchain for storage, and then not executing subsequent operations of the embodiment;
step 6, the signing terminal sends a second contract signing request (contract signing request) to the signing party B, wherein the second contract signing request comprises a target contract signed by the existing signing party A;
step 7, detecting whether a signing party B signs a target contract signed by an existing signing party A within a specified signing time, when the signing party B does not sign the target contract signed by the existing signing party A within the specified signing time, detecting an overdue unsigned target contract by a signing terminal, executing step 8 by the signing terminal, when the signing party B signs the target contract signed by the existing signing party A within the specified signing time, detecting the overdue unsigned target contract by the signing terminal, and executing step 19 by the signing terminal;
step 8, the signing terminal determines whether the target contract which is not signed for a long time comprises the signature of the signing party of the target contract, at the moment, the signing terminal executes step 9 because the signing party A signs the target contract and the target contract comprises the signature of the signing party A;
step 9, the signing terminal compares the number of overdue unsigned times included in the signing record with a first preset number of times and a second preset number of times, when the number of overdue unsigned times is less than or equal to the first preset number of times, the signing terminal executes the step 10, when the number of overdue unsigned times is more than the first preset number of times and less than or equal to the second preset number of times, the signing terminal executes the step 12, and when the number of overdue unsigned times is more than the second preset number of times, the signing terminal executes the step 17;
step 10, sending a second contract signing request to a signing party B (signing party not signing the target contract for an overdue period), detecting whether the signing party B signs the target contract signed by the existing signing party a within a specified signing time, and executing step 11 when the signing party B signs the target contract signed by the existing signing party a within the specified signing time; when the signatory B does not sign the target contract signed by the signatory A within the specified signing duration, updating the number of overdue unsigned times in the signing record and executing the step 9 based on the updated number of overdue unsigned times;
step 11, completing signing of the target contract to obtain a signed target contract, wherein the signed target contract has the signatures of a signing party A and a signing party B, and then subsequent operations of the embodiment are not executed;
step 12, the signing terminal sends a re-signing request to a signing party A (signed signing party of a target contract), the re-signing request comprises a target contract signed by the existing signing party A, the signing terminal determines whether a determined re-signing instruction sent by the signing party A for the re-signing request is received, when the signing terminal receives the determined re-signing instruction sent by the signing party A for the re-signing request, step 13 is executed, when the signing terminal receives a refusal re-signing instruction sent by the signing party A for the re-signing request, step 15 is executed;
step 13, the signing terminal sends a second contract signing request to the signing party B, detects whether the signing party B signs the target contract signed by the existing signing party A in the specified signing time, and executes step 14 when the signing party B signs the target contract signed by the existing signing party A in the specified signing time; when the signatory B does not sign the target contract signed by the signatory A within the specified signing duration, updating the number of overdue unsigned times in the signing record and executing the step 9 based on the updated number of overdue unsigned times;
step 14, completing signing of the target contract to obtain a signed target contract, wherein the signed target contract has the signatures of a signing party A and a signing party B, and then subsequent operations of the embodiment are not executed;
step 15, the signing terminal sets a preset watermark on the target contract to invalidate the target contract;
step 16, the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract; uploading the invalidation contract to the blockchain for storage, and then not executing subsequent operations of the embodiment;
step 17, the signing terminal sets a preset watermark on the target contract to invalidate the target contract;
step 18, the signing terminal signs the target contract provided with the preset watermark by using the private key of the public-private key pair to obtain a revocation contract; uploading the invalidation contract to the blockchain for storage, and then not executing subsequent operations of the embodiment;

In an optional embodiment, as shown in fig. 5, the method for processing an overdue contract based on a blockchain according to an embodiment of the present disclosure further includes the following steps:
step S310, in response to the target contract not including the signature of the signing party of the target contract, the signing terminal performs hash calculation on the target contract to obtain the verification information of the target contract.
When the signing terminal determines that the target contract does not include the signature of the signing party of the target contract, the signing terminal can perform hash calculation on the target contract through a hash algorithm, and correspondingly, the verification information of the target contract can be the hash value of the target contract.
In step S320, the verification information is bound with the revocation contract, and uploaded to the block chain for storage.
Wherein the verification information of the target contract can be bound with the voiding contract to form a corresponding relation between the verification information and the voiding contract.
In one implementation manner, when a user reuses a voided target contract, whether the voided target contract is modified is verified, the user can upload the voided target contract to a signing terminal, the signing terminal performs hash calculation on the voided target contract to obtain a hash value of the voided target contract, the signing terminal can obtain the voided contract corresponding to the voided target contract from a block chain and obtain verification information corresponding to the voided contract, the signing terminal determines whether the hash value of the voided target contract is the same as the verification information corresponding to the voided contract, and when the hash value of the voided target contract is the same as the verification information corresponding to the voided contract, the voided target contract is determined not to be modified.
