Description

Technical Field

[0001] This invention relates to the field of online payment technology, and in particular to a chain payment and settlement method and system with mutual guarantee functions. Background Technology

[0002] "Payment" is the settlement of debts and receivables, a one-way completion of fund transfers. Currently, both domestically and internationally, payment is the most common method for settling funds related to transactions. In payment settlement, considering the settlement needs of the seller or payee, and depending on the different transaction scenarios, commercial banks can provide the following main types of payment settlement services:

[0003] 1. Entrusted collection: Entrusted collection is a settlement method in which the payee entrusts a bank to collect funds from the payer;

[0004] 2. Collection and payment: Collection and payment is a settlement method in which the payee, after shipping the goods according to the purchase and sale contract, entrusts a bank to collect payment from the payer in another location, and the payer acknowledges payment to the bank.

[0005] 3. Letter of Credit: A letter of credit is a payment commitment made by the issuing bank to pay the inventor's invention upon presentation of documents that comply with the terms of the letter of credit.

[0006] 4. Jointly Managed Account: A jointly managed account is an account opened by Party A, Party B, and the bank based on a joint management account agreement for the joint management of funds;

[0007] 5. Bill of exchange business: Bill of exchange business refers to the routine business activities of credit institutions for the establishment, transfer and redemption of bills of exchange in accordance with certain methods and requirements.

[0008] Collection on behalf and collection on delivery are banking services that emphasize settlement convenience based on the payer's consent or commitment. They are still determined by the payer's will, and the success of collection remains uncertain.

[0009] Letters of credit are a risk transfer service. Besides their high cost, their documentary nature makes the process complex and inefficient. Like collection and payment agents, the payer does not provide actual funds as a guarantee for settlement.

[0010] A co-managed account is a temporary product or service provided by a single bank. The parties involved need to provide an agreement certificate that reflects their common will. The bank verifies each transaction before making the transfer payment. It cannot be used as a technical tool for interbank transactions and does not have the universality and wide applicability of transaction settlement.

[0011] Banks' bill business is based on commercial credit, combining bank credit and commercial credit. The credit risks it is prone to arise from mainly manifest in the risks associated with holding the bills, discounting, and repurchase agreements.

[0012] Current payment settlements are unidirectional and irreversible. Guarantees and guarantees require the involvement of a third party. Summary of the Invention

[0013] To address the aforementioned problems, the present invention aims to provide a chain payment and settlement method and system with mutual guarantee functions, which solves the problem that the fund transfer generated by existing payment technologies is completed solely by the payer according to their unilateral will, and the process is irreversible and unalterable, and mutual guarantee can be achieved without the intervention of a third party.

[0014] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0015] In a first aspect, in one embodiment of the present invention, a chain payment and settlement method with mutual guarantee functions is provided, including a chain order, a chain issuer, a chain bearer, a chain payment, chain payment, chain payment, chain period, payment settlement, return settlement, settlement settlement, payment extension order, entropy control period, and entropy reduction fund.

[0016] A blockchain transaction agreement is a written document in which both parties agree to mutually issue blockchain funds and manage them in a linked manner.

[0017] The person who initiates the chain link is called the chain issuer.

[0018] The party that confirms the validity of the interconnected transaction is called the "chain bearer".

[0019] Interconnected loans, which are loans made between each other, are called interconnected loans.

[0020] In transaction settlement, after the payer completes the disbursement, the commercial bank or payment institution provides custody guarantee services for the payment. At the same time, it grants both the payer and the payee equal rights to negotiate and assert the subsequent receipt of the payment. This is to meet the dynamic needs of transaction agreements and changes, and to mitigate the settlement risks for both the payer and payee. This settlement method, in which the payer and payee exercise mutual control over the payment, is called blockchain payment.

[0021] Chain payment is a payment method in which the payer disburses funds to the payee, and the commercial bank or payment institution fulfills its custody guarantee obligation for the disbursed funds. At the same time, the rules system of the commercial bank or payment institution also gives both the payer and the payee equal rights to negotiate and claim the subsequent return of the disbursed funds. This payment method of unilateral disbursement and mutual agreement on the return of funds is called chain payment.

[0022] The chain period is the time frame set for chain payments, from the time the funds are disbursed to the time the funds are automatically transferred to the payee. Once a chain payment subject to the chain period is disbursed, the creditor's claim and the payee's debt relationship are established as agreed.

[0023] Payment settlement refers to the act of a payer who chooses the blockchain payment settlement method to complete the disbursement of blockchain funds, and then transferring part or all of the blockchain funds to the payee through the services of a commercial bank or payment institution.

[0024] Refund refers to the act of a payee who chooses the blockchain payment and settlement method transferring part or all of the blockchain funds back to the payer through the services of a commercial bank or payment institution.

[0025] The term "clearing" refers to the mutual agreement between the payer and payee to clear the balance of the chain funds in one go. This involves transferring part or all of the remaining balance to the payer while simultaneously transferring the remaining chain funds to the payee. This process is executed after the payer's bill of lading is confirmed and becomes effective by the payee.

[0026] A payment extension order is an action taken by the payee to extend the time period for the automatic settlement of funds in the payment chain.

[0027] The entropy control period is the time period of 80% to 100% within the initially set chain period.

[0028] Entropy reduction funds are a type of quasi-chain fund used as collateral when the two parties to a transaction disagree on the netting of the chain fund balance. In order to ensure that the chain fund balance is netted according to the party's claim and to express this claim, one party must issue funds to the other party and entrust a commercial bank or payment institution to execute the remittance. The issuance of entropy reduction funds must be accompanied by a netting plan for the relevant chain fund balance.

[0029] As a further aspect of the present invention, the payment and return of the chain funds are collectively referred to as payment settlement.

[0030] Secondly, in one embodiment of the present invention, a blockchain payment and settlement method with mutual guarantee functions is provided, the method comprising the following steps:

[0031] S1. Obtain basic information of chain payment users and complete the signing of traditional contracts and installation of digital contracts;

[0032] S2. Based on their mutual consent or agreement, both parties choose the chain payment and settlement method. The chain issuer enters the chain payment and settlement system, selects the payee, completes the chain payment disbursement, and clarifies the amount of chain payment to be disbursed to the other party, i.e. the chain bearer, and sends a message to the chain bearer and its bank.

[0033] S3. The chain bearer enters the chain payment and settlement system, completes the chain payment disbursement according to the agreed amount, and sends a message to the chain issuer and its bank, thus forming an interconnected chain;

[0034] S4. Interchain funds are securely deposited into dedicated accounts of commercial banks or payment institutions and managed by blockchain payment and settlement application contracts.

[0035] S5. The mutual chain funds between the two parties can be cleared by the chain issuer and confirmed by the chain recipient, with the condition that each item is cleared to zero.

[0036] S6. If neither party objects, the chain period expires, and the mutual chain funds will be automatically paid to the other party, thus ending the transaction.

[0037] S7. Both the payer and payee have the right to negotiate and counterbalance each other when the other party is passively resistant, and can send relevant instructions through the blockchain payment and settlement system; during the entropy control period, either party in the inter-chain order can issue entropy reduction funds for their own inter-chain funds, resulting in the termination of the inter-chain order's association management with the inter-chain funds; the payer has the right to choose to issue entropy reduction funds first, and the payee can only choose to issue entropy reduction funds subsequently; the issuance of entropy reduction funds must be accompanied by a solution for clearing the relevant chain fund balance;

[0038] S8. After the linkage management between the two interconnected funds is terminated, the payer and payee of the two funds can perform operations such as payment release, return release, clearing, and payment extension.

[0039] S9. Upon expiration of the chain period, in accordance with the agreement reached between the payer and payee, the chain payment and settlement system will send an automatic instruction to instruct the commercial bank or payment institution to transfer the chain balance to the payee.

[0040] Thirdly, in one embodiment of the present invention, a blockchain payment and settlement system with mutual guarantee functions is provided, comprising:

[0041] The ChainPay user information acquisition module is used to acquire basic information about ChainPay users.

[0042] The blockchain payment and settlement system interaction module is used by the blockchain issuer and the blockchain recipient to send instructions or have the system execute automatic instructions based on the permissions granted by the blockchain payment and settlement application contract after the blockchain issuer and the blockchain recipient have completed the mutual disbursement of blockchain funds, thereby completing the transfer of all or part of the blockchain funds from the remittance account to the accounts of the payer and recipient.

[0043] The blockchain payment and settlement middleware module is used for the transmission of instructions between the blockchain payment and settlement interaction module and the systems of commercial banks or payment institutions.

[0044] The chain payment and settlement system with mutual guarantee functions also includes:

[0045] The identity verification module is used to verify the identity information of the chain payment user and execute the instructions issued by the user after the identity verification is successful.

[0046] The risk control management module is used to manage the risk of users of the chain payment system.

[0047] The query and statistics module is used to query and analyze past transaction records and account details, as well as query and print transaction vouchers.

[0048] Furthermore, to achieve the above objectives, the present invention also provides a chain payment and settlement device with mutual guarantee function. The chain payment and settlement device with mutual guarantee function includes a processor, a memory, and a chain payment and settlement program with mutual guarantee function stored in the memory and executable by the processor. When the chain payment and settlement program with mutual guarantee function is executed by the processor, it implements the steps of the chain payment and settlement method with mutual guarantee function as described above.

[0049] Furthermore, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a chain payment and settlement program with mutual guarantee functions, wherein when the chain payment and settlement program with mutual guarantee functions is executed by a processor, it implements the steps of the chain payment and settlement method with mutual guarantee functions as described above.

[0050] The technical solution provided by this invention has the following beneficial effects:

[0051] 1. This chain payment and settlement method and system with mutual guarantee function integrates payment and settlement with decentralized and mutually restrictive authority, so that transaction decisions no longer depend on the credit recognition and assessment between trading counterparties. Zero credit settlement promotes the prevalence of unfamiliar and chance transactions, and greatly increases the enthusiasm and prevalence of transactions.

[0052] 2. This chain-based payment and settlement method and system, with its mutual guarantee function, provides tangible security for settlement funds and resolves the fundamental issues surrounding the evolution of creditor and debtor relationships under credit sales transactions. It allows for full negotiation between the transacting parties, reducing the probability of litigation. Furthermore, legal enforcement in cases of litigation becomes simpler and more secure, significantly lowering social legal costs.

[0053] 3. This chain payment and settlement method and system with mutual guarantee function limits the negotiation and mutual restraint between the two parties in the transaction on fund settlement, and maximizes the matching, response and synchronization of the settlement process and the supply process, which greatly improves production efficiency and production planarity.

[0054] 4. This chain-based payment and settlement method and system, with its mutual guarantee function, will make international settlements safer and more convenient through a secure and reliable chain-based payment and settlement model. Factoring and credit insurance transactions in international trade will be significantly reduced, thereby lowering trade costs.

[0055] 5. This blockchain-based payment and settlement method and system, with its mutually reinforcing functions, ensures secure and reliable fund settlement, promoting active and orderly production and consumption. Market participants all need to control settlement risks and hope for new technologies to address the inherent pain points and difficulties in transactions, especially credit sales, as well as the uncertainty of fund settlement. Blockchain payment provides real funds for settlement, granting both payers and payees the right to control the payment's receipt and refund, and the right to negotiate and check the other party's passive exercise of these rights. It can meet the numerous needs of both payers and payees regarding transaction agreements, transaction changes, and settlement security.

[0056] These or other aspects of the invention will become more apparent from the following description of embodiments. It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention.

[0065] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0066] An embodiment of the present invention provides a chain payment and settlement method with mutual guarantee functions, including: inter-chain order, chain issuer, chain bearer, inter-chain payment, chain payment, chain payment, chain period, payment settlement, return settlement, settlement settlement, payment extension order, entropy control period, and entropy reduction fund.

[0067] A blockchain transaction agreement is a written document in which both parties agree to mutually issue blockchain funds and manage them in a linked manner.

[0068] The person who initiates the chain link is called the chain issuer.

[0069] The party that confirms the validity of the interconnected transaction is called the "chain bearer".

[0070] Interconnected loans, which are loans made between each other, are called interconnected loans.

[0071] In transaction settlement, after the payer completes the disbursement, the commercial bank or payment institution provides custody guarantee services for the payment. At the same time, it grants both the payer and the payee equal rights to negotiate and assert the subsequent receipt of the payment. This is to meet the dynamic needs of transaction agreements and changes, and to mitigate the settlement risks for both the payer and payee. This settlement method, in which the payer and payee exercise mutual control over the payment, is called blockchain payment.

[0072] Chain payment is a payment method in which the payer disburses funds to the payee, and the commercial bank or payment institution fulfills its custody guarantee obligation for the disbursed funds. At the same time, the rules system of the commercial bank or payment institution also gives both the payer and the payee equal rights to negotiate and claim the subsequent return of the disbursed funds. This payment method of unilateral disbursement and mutual agreement on the return of funds is called chain payment.

[0073] The chain period is the time frame set for chain payments, from the time the funds are disbursed to the time the funds are automatically transferred to the payee. Once a chain payment subject to the chain period is disbursed, the creditor's claim and the payee's debt relationship are established as agreed.

[0075] Refund refers to the act of a payee who chooses the blockchain payment and settlement method transferring part or all of the blockchain funds back to the payer through the services of a commercial bank or payment institution.

[0076] The release and return of funds in a blockchain project are collectively referred to as fund release.

[0077] The term "clearing" refers to the mutual agreement between the payer and payee to clear the balance of the chain funds in one go. This involves transferring part or all of the remaining balance to the payer while simultaneously transferring the remaining chain funds to the payee. This process is executed after the payer's bill of lading is confirmed and becomes effective by the payee.

[0078] A payment extension order is an action taken by the payee to extend the time period for the automatic settlement of funds in the payment chain.

[0079] The entropy control period is the time period of 80% to 100% within the initially set chain period.

[0080] Entropy reduction funds are a type of quasi-chain fund used as collateral when the two parties to a transaction disagree on the netting of the chain fund balance. In order to ensure that the chain fund balance is netted according to the party's claim and to express this claim, one party must issue funds to the other party and entrust a commercial bank or payment institution to execute the remittance. The issuance of entropy reduction funds must be accompanied by a netting plan for the relevant chain fund balance.

[0081] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the blockchain payment and settlement method with mutual guarantee function according to the present invention. In an embodiment of the present invention, the blockchain payment and settlement method with mutual guarantee function includes the following steps S1-S9:

[0082] S1. Obtain basic information of chain payment users and complete the signing of traditional contracts and installation of digital contracts;

[0083] S2. Based on their mutual consent or agreement, both parties choose the chain payment and settlement method. The chain issuer enters the chain payment and settlement system, selects the payee, completes the chain payment disbursement, and clarifies the amount of chain payment to be disbursed to the other party, i.e. the chain bearer, and sends a message to the chain bearer and its bank.

[0084] S3. The chain bearer enters the chain payment and settlement system, completes the chain payment disbursement according to the agreed amount, and sends a message to the chain issuer and its bank, thus forming an interconnected chain;

[0085] S4. Interchain funds are securely deposited into dedicated accounts of commercial banks or payment institutions and managed by blockchain payment and settlement application contracts.

[0086] S5. The mutual chain funds between the two parties can be cleared by the chain issuer and confirmed by the chain recipient, with the condition that each item is cleared to zero.

[0087] In embodiments of the present invention, the two parties to the transaction cannot make payments, returns, or clear out the funds between the two parties on the mutual chain. Instead, the mutual chain funds can be cleared out on the condition that the chain issuer initiates the clearing process and the chain bearer confirms it.

[0088] S6. If neither party objects, the chain period expires, and the mutual chain funds will be automatically paid to the other party, thus ending the transaction.

[0089] S7. Both the payer and payee have the right to negotiate and counterbalance each other when the other party is passively resistant, and can send relevant instructions through the blockchain payment and settlement system; during the entropy control period, either party in the inter-chain order can issue entropy reduction funds for their own inter-chain funds, resulting in the termination of the inter-chain order's association management with the inter-chain funds; the payer has the right to choose to issue entropy reduction funds first, and the payee can only choose to issue entropy reduction funds subsequently; the issuance of entropy reduction funds must be accompanied by a solution for clearing the relevant chain fund balance;

[0090] In embodiments of the present invention, during the entropy control period and / or the extended period, if the two parties to the transaction disagree on the netting of the chain balance, the payer has the right to choose to pay the entropy reduction fund first, and the payee can only choose to pay the entropy reduction fund subsequently; the payment of the entropy reduction fund must be accompanied by a netting plan for the relevant chain balance, and the payment of the entropy reduction fund is irrevocable and executed immediately; the payer pays the entropy reduction fund at a certain percentage of the amount claimed for return, and the payee pays the entropy reduction fund at a certain percentage of the difference between the amount claimed for return and the amount claimed for return by the payer; the payer's payment of the entropy reduction fund causes the existing chain period of the relevant chain balance to be automatically extended by 3 days, and active payment, return, netting, and chain reconnection cannot be achieved. The chain period is extended; if entropy reduction funds are disbursed during the entropy control period, the payment extension order becomes invalid; if the payee does not disburse entropy reduction funds along with the payer until the chain period expires, the chain balance will be automatically cleared and the entropy reduction funds will be returned according to the clearing plan provided by the payer; if the payee disburses entropy reduction funds along with the payer, the chain balance will be automatically cleared according to the amount claimed to be paid to the other party in the clearing plan of both parties, and the remaining chain funds, together with the entropy reduction funds of both parties, will extend the chain period for another 90 days and restore the clearing function. From then on, both parties can: clear the chain balance to automatically return the entropy reduction funds; clear the entropy reduction funds and the chain balance separately as a condition; when the chain period expires, the chain balance will be automatically paid out, and the entropy reduction funds of both parties will be automatically returned.

[0091] S8. After the linkage management between the two interconnected funds is terminated, the payer and payee of the two funds can perform operations such as payment release, return release, clearing, and payment extension.

[0092] S9. Upon expiration of the chain period, in accordance with the agreement reached between the payer and payee, the chain payment and settlement system will send an automatic instruction to instruct the commercial bank or payment institution to transfer the chain balance to the payee.

[0093] In an embodiment of the present invention, upon the expiration of the chain period, the chain payment and settlement system will send an automatic instruction to instruct the commercial bank or payment institution to transfer the chain balance to the payee. The chain period, as a mandatory means of payment transfer, is the basis for confirming the creditor-debtor relationship.

[0094] In some embodiments of the present invention, if the outstanding balance of the chain payment is not cleared and one party initiates litigation, the payer and payee should actively execute the judgment; otherwise, the relevant commercial bank or payment institution will be subject to enforcement by the authorized entity. If the plaintiff holds the relevant commercial bank or payment institution as a third party with joint liability, and the judgment does not stipulate that the relevant commercial bank or payment institution has liability for compensation, the plaintiff's access to the chain payment system will be automatically closed, and the closure period can be set.

[0095] The blockchain payment and settlement method with mutual guarantee functions in this invention integrates payment and receipt, decentralizing and mutually restraining each other during settlement. This eliminates reliance on credit recognition and assessment between trading partners, promoting zero-credit settlement and encouraging transactions between strangers and chance encounters, significantly increasing the enthusiasm and prevalence of transactions. The practical guarantee of settlement funds resolves the fundamental issues of debt evolution under credit sales conditions. Both parties can fully negotiate, reducing the probability of litigation, while legal enforcement in cases of litigation becomes simpler and more secure, greatly reducing social legal costs. The mutual restraint and negotiation between the two trading parties in fund settlement maximizes the matching, responsiveness, and synchronization of the settlement process with the supply process, significantly improving production efficiency and plannability. The safe and reliable blockchain payment and settlement model will make international settlement safer and more convenient. Factoring and credit insurance in international trade will be greatly reduced, lowering trade costs. Ensuring safe and reliable fund settlement promotes active and orderly production and consumption. Market participants need to control settlement risks and hope for new technologies to address the inherent pain points and difficulties in transactions, especially credit sales, as well as the uncertainty of fund settlement. ChainPayment provides real-world funds for settlement, granting both payers and payees the right to control the payment's disbursement and refund, and the right to negotiate and check the other party's passive exercise of these rights. It can meet numerous needs of both payers and payees regarding transaction agreements, transaction changes, and settlement security.

[0096] In some embodiments, see Figure 2 As shown, the present invention also provides a blockchain payment and settlement system with mutual guarantee functions, comprising:

[0097] The ChainPay user information acquisition module 100 is used to acquire basic information of ChainPay users;

[0098] The Chain Payment and Settlement System Interaction Module 200 is used by the chain issuer and chain recipient to send instructions or execute automatic instructions using the permissions granted by the Chain Payment and Settlement Application Contract after completing the mutual disbursement of chain funds, so as to complete the transfer of all or part of the chain funds from the remittance account to the accounts of the two parties.

[0099] The Chain Payment and Settlement Middleware Module 300 is used for the transmission of instructions between the Chain Payment and Settlement Interaction Module and the systems of commercial banks or payment institutions.

[0100] The identity verification module 400 is used to verify the identity information of the chain payment user and execute the instructions issued by the user after the identity verification is successful.

[0102] The query and statistics module 600 is used to query and statistically analyze past transaction records and account details, as well as query and print transaction vouchers.

[0103] In this context, each module in the aforementioned chain payment and settlement system with mutual guarantee functions corresponds to each step in the aforementioned chain payment and settlement method embodiment with mutual guarantee functions, and its functions and implementation process will not be described in detail here.

[0104] The chain payment and settlement method and apparatus with mutual guarantee function of the present invention can be implemented in the form of a computer program, which can run on a chain payment and settlement device with mutual guarantee function. The chain payment and settlement device with mutual guarantee function includes a processor and a memory connected via a system bus, wherein the memory may include non-volatile storage media and internal memory.

Claims

1. A chain payment and settlement method with mutual guarantee functions, characterized in that, This includes inter-chain transactions, chain issuers, chain bearers, inter-chain funds, chain payments and receipts, chain funds, chain periods, payment settlement, return settlement, settlement of funds, net settlement, payment extension slips, entropy control periods, and entropy reduction funds; A blockchain transaction agreement is a written document in which both parties agree to mutually issue blockchain funds and manage them in a linked manner. The person who initiates the chain link is called the chain issuer. The party that confirms the validity of the interconnected transaction is called the "chain bearer". Interconnected loans, which are loans made between each other, are called interconnected loans. In transaction settlement, after the payer completes the payment, the commercial bank or payment institution provides custody guarantee services for the payment. At the same time, it grants both the payer and the payee equal rights to negotiate and assert the subsequent receipt of the payment. This is to meet the dynamic needs of transaction agreements and changes, and to mitigate the settlement risks for both the payer and payee. This settlement method, in which the payer and payee exercise mutual control over the payment, is called blockchain payment. Chain payment is a payment method in which the payer disburses funds to the payee, and the commercial bank or payment institution fulfills its custody guarantee obligation for the disbursed funds. At the same time, the rules system of the commercial bank or payment institution also gives both the payer and the payee equal rights to negotiate and claim the subsequent return of the disbursed funds. This payment method of unilateral disbursement and mutual agreement on the return of funds is called chain payment. The chain period is the time frame set for chain payments, from the time the funds are disbursed to the time the funds are automatically transferred to the payee. Once a chain payment subject to the chain period is disbursed, the creditor's claim and the payee's debt relationship are established as agreed. Payment settlement refers to the act of a payer who chooses the blockchain payment settlement method to complete the disbursement of blockchain funds, and then transferring part or all of the blockchain funds to the payee through the services of a commercial bank or payment institution. Refund refers to the act of a payee who chooses the blockchain payment and settlement method transferring part or all of the blockchain funds back to the payer through the services of a commercial bank or payment institution. The term "clearing" refers to the mutual agreement between the payer and payee to clear the balance of the chain funds in one go. This involves transferring part or all of the remaining balance to the payer while simultaneously transferring the remaining chain funds to the payee. This process is executed after the payer's bill of lading is confirmed and becomes effective by the payee. A payment extension order is an action taken by the payee to extend the time period for the automatic settlement of funds in the payment chain. The entropy control period is the time period of 80% to 100% within the initially set chain period. Entropy reduction gold is a quasi-chain fund that serves as a guarantee measure when the two parties to a transaction disagree on the netting of the chain fund balance. In order to ensure that the chain fund balance is netted according to the party's claim and to express this claim, the party must issue funds to the other party and entrust a commercial bank or payment institution to execute the remittance. This blockchain payment and settlement method with mutual guarantee functions includes the following steps: S1. Obtain basic information of chain payment users and complete the signing of traditional contracts and installation of digital contracts; S2. Based on their mutual consent or agreement, both parties choose the chain payment and settlement method. The chain issuer enters the chain payment and settlement system, selects the payee, completes the chain payment disbursement, and clarifies the amount of chain payment to be disbursed to the other party, i.e. the chain bearer, and sends a message to the chain bearer and its bank. S3. The chain bearer enters the chain payment and settlement system, completes the chain payment disbursement according to the agreed amount, and sends a message to the chain issuer and its bank, thus forming an interconnected chain; S4. Interchain funds are securely deposited into dedicated accounts of commercial banks or payment institutions and managed by blockchain payment and settlement application contracts. S5. The liquidation of mutual chain funds is conditional upon the chain issuer initiating the process and the chain bearer confirming it, with each item being cleared to zero. However, neither party can make payment, return, or liquidation for mutual chain funds on a single party. S6. If neither party objects, the chain period expires, and the mutual chain funds will be automatically paid to the other party, thus ending the transaction. S7. Both the payer and payee have the right to negotiate and counterbalance each other when the other party is passively resistant, and send relevant instructions through the blockchain payment and settlement system; during the entropy control period, either party in the inter-chain transaction has the right to deduct entropy reduction funds from their own inter-chain funds, resulting in the termination of the inter-chain transaction's association management of the inter-chain funds; the payer has the right to choose to deduct entropy reduction funds first, and the payee can only choose to deduct entropy reduction funds subsequently; the deduction of entropy reduction funds must be accompanied by a solution for clearing the relevant chain fund balance; during the entropy control period and / or the extended period, if the two parties have a dispute over the clearing of the chain fund balance, the deduction of entropy reduction funds is irrevocable and executed immediately; the payer deducts entropy reduction funds according to a certain percentage of the amount they claim to be returned, and the payee deducts entropy reduction funds according to a certain percentage of the difference between the amount they claim to be returned and the amount claimed by the payer; the payer deducts... Entropy reduction funds automatically extend the existing chain duration of related blockchain funds by 3 days, and active payment, refund, clearing, and chain duration extension are not possible. During the entropy control period, if entropy reduction funds are disbursed, the payment extension order becomes invalid. If the payee does not disburse entropy reduction funds along with the payer until the chain duration expires, the chain balance will be automatically cleared according to the clearing plan provided by the payer, and the entropy reduction funds will be returned. If the payee disburses entropy reduction funds along with the payer, the chain balance will be automatically disbursed according to the amount claimed to be disbursed to the other party in the clearing plan between the two parties. The remaining chain balance, along with the entropy reduction funds from both parties, will extend the chain duration by 90 days and restore the clearing function. From this point on, both parties have the right to automatically refund the entropy reduction funds by clearing the chain balance. Clearing is conditional on the separate clearing of entropy reduction funds and the chain balance. Upon the chain duration expires, the chain balance will be automatically disbursed, and the entropy reduction funds from both parties will be automatically refunded. S8. After the linkage management between the two linked funds is terminated, both the payer and payee of the two linked funds have the right to exercise the functions of payment release, return, clearing, and payment extension. S9. Upon expiration of the chain period, in accordance with the agreement reached between the payer and payee, the chain payment and settlement system will send an automatic instruction to instruct the commercial bank or payment institution to transfer the chain balance to the payee; among them, the chain period, as a mandatory means of payment transfer, is the basis for confirming the creditor-debtor relationship; If the outstanding balance of the chain payment cannot be settled, and one party initiates litigation, the payer and payee should actively comply with the judgment; otherwise, the relevant commercial bank or payment institution will be subject to enforcement by the authorized entity. If the plaintiff holds the relevant commercial bank or payment institution as a third party with joint liability, and the judgment does not stipulate that the relevant commercial bank or payment institution is liable for compensation, the plaintiff's access to the chain payment system will be automatically closed, and the closure period can be set.
