Background technique

Property enforcement refers to the act of collecting the property of the person (individual or legal person) who is in debt, based on the results of judicial decisions, by a judicial institution (generally a court). In judicial practice, many executors deliberately transfer and hide property in order to evade payment of debts, resulting in a judicial decision that is ineffective and cannot be executed.

In addition, with the rise of blockchain technology, in the future, individual or legal person property accounts may no longer be managed by a single management agency, but by a blockchain network composed of multiple management agencies.

detailed description

Here, we first explain some concepts that will be used later.

Executing Party : Refers to the agency or the staff of the agency responsible for executing the property of the person subject to execution (legal person or individual) in judicial practice. For example, the executing party may be a court, a court executive bureau, an executive judge of the court executive bureau, etc.

Execution user : the individual or legal person who is in debt according to law.

Application execution user : an individual or legal person who has a claim against the executed user according to law, can apply to the executing party to perform property execution on the executed user.

Execution Amount: The amount of debt that the executed user owes to the application execution user, that is, the amount that the executing party will collect for the executed user.

Locked amount : Part or all of the user's property account that the user has no right to dispose of is the locked amount of the user's property account. When there is more than one user's property account, the account types corresponding to the user's property accounts are also different. For example, user Zhang San has three property accounts, namely savings account, pension account and provident fund account.

In addition, when the user has more than one property account, each property account can have a corresponding locked sub-amount, each property account can have a different locked sub-amount, and the sum of the locked sub-amounts of each property account is that the user has no The locked amount of the right to punish. In other words, the locked amount is shared by the locked sub-amount of each user's property account. For example, if the user Zhang San has no right to dispose of the locked amount of 100,000 yuan, then the user Zhang San ’s savings account can have a locked sub-amount of 50,000, the pension account can have a locked sub-amount of 30,000, and the provident fund account can have a locked sub-amount The amount can be 20,000.

Amount of apportionment : If there is more than one property account of the executed user, when the executing party performs property execution on the executed user, for any property account of the executed user, the amount deducted from the property account is the corresponding property account Apportioned amount. In other words, the execution amount is allocated by all or part of the user's property account.

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail in conjunction with the drawings in the embodiments of the present specification. Obviously, the described implementation Examples are only a part of the embodiments of this specification, but not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection.

The technical solutions provided by the embodiments of this specification will be described in detail below in conjunction with the drawings.

FIG. 1 is a schematic flowchart of a blockchain-based property execution method provided by an embodiment of this specification, including the following steps:

S100: The executor device obtains the execution amount and the executed user ID.

In the embodiment of the present specification, for each user, part or all of the amount of the user's property account is set as the locked amount that the executed user has no right to dispose of. Among them, the user has no right to dispose of the locked amount, which means that the user cannot perform withdrawal, transfer or any other disposition operation on the locked amount.

For example, for the personal user Zhang San, the balance of Zhang San ’s property account is 100,000, and 30,000 in Zhang San ’s property account can be set as the locked amount that Zhang San has no right to dispose of. For another example, for the corporate user A company, the balance of the company A ’s property account is 1 million, and the 200,000 in the company A ’s property account can be set as the locked amount that the company A has no right to dispose of.

In this way, for any user, when the user owes debts to others according to law but refuses to repay, the executor can execute the property of the user based on the locked amount of the user's property account.

In the embodiment of this specification, for each user, the locked amount of the user's property account is determined as follows:

Obtain the credit score corresponding to the user; the credit score corresponding to the user is positively related to the credit evaluation of the user; determine the locked amount of the user's property account based on the balance of the user's property account and the credit score corresponding to the user; The locked amount of the user's property account is positively related to the balance of the user's property account, and the locked amount of the user's property account is negatively related to the credit score corresponding to the user.

Among them, in practical applications, the credit score corresponding to the user may be given by a blockchain network that is responsible for performing credit evaluation services.

In the embodiment of the present specification, the executor device may specifically be a server, computer, mobile phone, or other device of the executor. It should be noted that in practical applications, a blockchain network (may be referred to as a judicial blockchain network) for performing judicial-related businesses can be constructed in the judicial field. The nodes in the judicial blockchain network can be various Equipment of high-level courts, public security organs and procuratorates. In this case, the executor device may be a node in the judicial blockchain network.

In step S100, the executor device may receive the execution amount input by the executor and the executed user identification.

S102: The executor device sends the execution amount and the executed user identification to the blockchain network.

S104: Each node in the blockchain network publishes the execution transaction including the execution amount and the executed user identification to the blockchain based on the consensus mechanism.

The blockchain network in step S102 may be a blockchain network responsible for managing the user's property account. For example, the blockchain network may be an alliance chain network composed of major banks, and a node in the alliance chain network is a bank device.

In steps S102 to S104, the executor device may send the execution amount and the executed user ID to the blockchain network, and then, each node in the blockchain network will be based on a consensus mechanism to The execution transaction including the execution amount and the executed user identification is released to the blockchain for certificate deposit.

It should be noted that the transaction described in this specification refers to a piece of data that a user creates through a client of the blockchain and needs to be finally released to the distributed database of the blockchain.

That is to say, there are narrow transactions and broad transactions in the transactions in the blockchain. The narrow sense of the transaction refers to a value transfer issued by the user to the blockchain; for example, in the traditional Bitcoin blockchain network, the transaction can be a transfer initiated by the user in the blockchain. The generalized transaction refers to a piece of business data with business intent published by the user to the blockchain; for example, the operator can build an alliance chain based on actual business needs, relying on the alliance chain to deploy some other types that are not related to value transfer Online business (for example, rental business, vehicle scheduling business, insurance claims business, credit service, medical service, etc.), and in this type of alliance chain, the transaction can be a business with business intent issued by the user in the alliance chain Message or business request.

Based on this, there are two situations:

1. In step S102, the executor device may send an execution instruction including the execution amount and the executed user identification to any node in the blockchain network (herein referred to as a target node) ), The target node may construct the above-mentioned execution transaction based on the execution instruction, and broadcast the execution transaction to other nodes in the blockchain network.

For case 1, further, in step S102, the executor device uses its own private key to sign the execution instruction including the execution amount and the executed user identification, and, the signed execution The instruction is sent to the target node. Correspondingly, the target node may use the public key of the executor's device to sign and verify the execution instruction, and then construct an execution transaction based on the execution instruction.

In practice, property execution is a judicial act that only a specific law enforcement agency has the right to perform. Therefore, the target node needs to ensure that the device that sends the execution instruction to it is the device of the executing party.

2. In step S102, the executor device may also construct an execution transaction containing the execution amount and the executed user identification, and then broadcast the execution transaction to each node in the blockchain network.

For case 2, further, in practice, if only the nodes in the blockchain network have the authority to construct the transaction, then the executor device generally does not have the authority to construct the above-mentioned execution transaction. Therefore, the executor device can obtain the account management private key provided by the blockchain network, thereby having the authority to initiate transactions outside the blockchain network.

Specifically, in step S102, the executor device uses the account management private key provided by the blockchain network to sign the execution transaction including the execution amount and the executed user ID, and The executed transaction is broadcast to each node in the blockchain network. Correspondingly, in step S104, after each node in the blockchain network uses the account management public key corresponding to the account management private key to sign and verify the execution transaction, based on the consensus mechanism, it will include all The execution amount of the execution amount and the executed user identification are released to the blockchain.

S106: Each node in the blockchain network deducts money from the locked amount of the property account corresponding to the executed user ID based on the execution amount.

In the embodiment of the present specification, each node in the blockchain network may be pre-deployed with a smart contract for implementing property execution logic. As such, in step S106, each node in the blockchain network can call the smart contract to operate on the property account corresponding to the managed executed user ID, and from the executed user ID based on the execution amount The corresponding amount is deducted from the locked amount of the property account.

Specifically, for each node in the blockchain network, if it is determined that the execution amount is less than the locked amount of the property account corresponding to the executed user ID, the node may select from the executed user ID The execution amount is deducted from the locked amount of the corresponding property account; if it is determined that the execution amount is not less than the locked amount of the property account corresponding to the executed user ID, the node may select the corresponding amount from the executed user ID In the property account, the locked amount of the property account corresponding to the executed user ID is deducted.

In the embodiment of the present specification, each node in the blockchain network may transfer the amount of the deduction to the executing party or apply for execution after deducting the amount from the locked amount of the property account corresponding to the executed user ID user.

Further, if the executor also opens a property account in the blockchain network, then each node in the blockchain network deducts the money from the locked amount of the property account corresponding to the executed user ID After that, the deduction amount can be added to the property account of the executor user.

If the application execution user also opens a property account in the blockchain network, then the execution transaction may also include the application execution user ID obtained by the executor device. Therefore, each node in the blockchain network deducts the deduction from the locked amount of the property account corresponding to the executed user ID, and then adds the deduction amount to the property account corresponding to the application execution user ID.

With the method shown in FIG. 1, for each user, part or all of the user ’s property account amount is set as the locked amount that the executed user does not have the right to dispose of. The user's property account is managed by the blockchain network. When the executing party needs to execute the property execution for the executed user, it can directly send the execution amount to be executed and the user ID of the executed user to the blockchain network. Each node in the blockchain network will contain the execution amount After the execution transaction with the executed user ID is released to the blockchain for certificate storage, a deduction will be made from the locked amount of the property account corresponding to the executed user ID based on the execution amount. In this way, the executor can successfully execute the property of the user to be executed, which solves the problem of difficult property execution. In addition, the property execution records of the executor will also be posted on the blockchain, which cannot be eliminated or tampered with.

In addition, in practical applications, users can have property accounts of different account types, such as savings accounts, pension accounts, provident fund accounts, medical insurance accounts, and so on.

Therefore, in the embodiment of the present specification, a corresponding locked amount can be set for each user's property account of a different account type. It should be noted that users who have at least two property accounts with different account types generally refer to individual users. Because in practice, the account type corresponding to the legal person user's property account is generally a savings type, while individual users can have property accounts of different account types, such as savings account, provident fund account, pension account, etc.

In the embodiment of this specification, taking any user as an example, for each property account of the user, part or all of the property account is set as a locked sub-amount that the user does not have the right to dispose of, and each property account of the user The sum of the locked sub-amounts is the locked amount that the user has no right to dispose of.

As such, in step S102, the executor device selects at least one property account from each property account of the executed user as the target property account, and determines the allocation amount corresponding to each target property account according to the execution amount. Then, for each target property account, the executor device sends the assessed amount corresponding to the target user account of the executed user ID to the blockchain network.

Among them, the sum of the apportioned amounts corresponding to the respective target property accounts is the execution amount. It should also be noted that, in the embodiments of the present specification, the blockchain network responsible for managing property accounts of various account types may be the same blockchain network, or may not be the same blockchain network.

Based on this, in steps S104-S106, each node in the blockchain network may, for each target property account, based on the consensus mechanism, will include the apportioned amount of the executed user ID corresponding to the target property account The execution sub-transaction is published to the blockchain; then the deduction amount corresponding to the target property account is deducted from the locked sub-value of the target property account.

Further, the locked sub-amount of each user's property account can be determined as follows:

First, sort each user's property account.

Second, according to the locked amount that the user has no right to dispose of, select the top N property accounts. Among them, N is not greater than M, the sum of the balance of the first N property accounts is not less than the locked amount of the user's no right to dispose, and the sum of the balance of the first N-1 property accounts is less than the locked amount of the user's no right to dispose; M is The number of property accounts for this user.

Then, for each of the first N-1 property accounts, the balance of the property account is determined as the locked sub-value of the property account; and, the locked amount that the user does not have the right to dispose of is subtracted from the previous N-1 The difference of the sum of the balances of the property accounts is determined as the locked sub-amount of the Nth property account; and, if N is less than M, the locked sub-amount of the unselected MN property accounts is also determined to be zero.

It should be noted that the above rules for sorting each user's property account can be specified according to actual needs.

For example, suppose user Zhang San has a savings account (balance is 1 million), a pension account (balance is 200,000) and a provident fund account (balance is 500,000). According to the common sense of life, users can withdraw the amount in the savings account at will, and users usually need to meet certain conditions (such as after retirement or to buy a house) before they can withdraw the amount in the pension account and provident fund account. Based on this, if Zhang San ’s credit is good, he may consider giving priority to the amount in Zhang San ’s pension account and provident fund account when locking Zhang San ’s property. Therefore, the three property accounts of Zhang San can be sorted into pension account-provident fund account-savings account from front to back. Assuming that Zhang San has no right to dispose of the locked amount of 800,000, then the balance of Zhang San ’s pension account and provident fund account can all be used as the locked sub amount, and 100,000 in Zhang San ’s savings account can be used as the locked sub amount.

Of course, if Zhang San ’s credit is poor, he may also consider giving priority to the amount in Zhang San ’s savings account when Zhang San ’s property is locked, until the balance of Zhang San ’s savings account is all set as the locked sub-amount.

When performing property execution on the executed user, first of all, it is necessary to select the property account to be requisitioned from each property account of the executed user as the target property account. In addition, the amount to be allocated for each target property account must be determined based on the execution amount. A person skilled in the art can easily think of a variety of ways to determine the target property account (for example, random selection), and a way to determine the allocation amount corresponding to each target property account. In short, for each target property account, the apportioned amount corresponding to the target property account is not greater than the locked amount of the target property account, and the sum of the apportioned amounts corresponding to the target property accounts is the execution amount.

Further, the target property account may be determined according to the order in which the above property accounts are arranged. Specifically, the executor device selects the first S property accounts as the target property account. Among them, S is not greater than M; the sum of the locked sub-amounts of the first S property accounts is not less than the execution amount, and the sum of the locked sub-amounts of the first S-1 property accounts is less than the execution amount.

In this way, following the above example, the order of Zhang San ’s property accounts is pension account-provident fund account-savings account, then the execution order of Zhang San ’s property is also pension account-provident fund account-savings account. After the current locked sub-amount of the property account is used up, the locked sub-amount of the next property account will be executed. Assuming that the executing party needs to collect 500,000 for Zhang San (the execution amount is 500,000), then since the sum of the locked sub-amounts of Zhang San ’s pension account and provident fund account is enough to pay the execution amount, Zhang can Three's pension account and provident fund account are determined as the target property account, there is no need to determine Zhang San's savings account as the target property account.

In addition, the method for determining the amount of apportionment corresponding to each target property account may be:

For each target property account in the previous S-1 target property accounts, determine the locked sub-amount of the target property account as the apportioned amount corresponding to the target property account; and, subtract the previous S-1 from the execution amount The difference between the sum of the locked sub-amounts of each target property account is determined as the apportioned amount corresponding to the Sth property account.

Still using the above example, since Zhang San ’s pension account and provident fund account are the target property accounts, first of all, for Zhang San ’s pension account, the corresponding locked sub-amount of 200,000 is determined as the corresponding amount of the pension account, and then, For Zhang San's provident fund account, 300,000 of the corresponding locked sub-amount of 500,000 is determined as the corresponding apportioned amount of the provident fund account.

The system shown in FIG. 2 includes: an executor device and a blockchain network, and the blockchain network is responsible for managing a user ’s property account ;

In Figure 2, there are two blockchain networks, namely the judicial blockchain network and the blockchain network (which can be composed of banks) responsible for managing the user's property account. Each user usually has only one account type of property account.

Among them, any node in the judicial blockchain network as the executing party device initiates execution of the property of the executed user. The executor device first obtains the execution amount and the executed user identification, and then sends the execution amount and the executed user identification to the blockchain network for property execution.

3 is a schematic structural diagram of another blockchain-based property execution system provided by an embodiment of this specification. In Figure 3, there are four blockchain networks, namely the judicial blockchain network, the blockchain network responsible for managing savings accounts (which can be composed of banks), and the blockchain network responsible for managing pension accounts (may It is composed of the pension management institutions in various places) and the blockchain network responsible for managing the provident fund accounts (which can be composed of various provident fund management institutions). Among them, any node in the judicial blockchain network as the executing party device initiates execution of the property of the executed user. The executor device first obtains the execution amount and the executed user identification, and then selects at least one property account of the executed user as the target property account according to the execution amount and the locked sub-amount of each property account of the executed user (in turn select pension Gold account, provident fund account as the target property account), and determine the corresponding amount of each target property account. Then, the executor's device can execute property execution for the blockchain network corresponding to each target property account.

Based on the blockchain-based property execution device shown in FIG. 1, the embodiment of this specification also correspondingly provides a blockchain-based property execution device. As shown in FIG. 4, for each user, the user ’s property account Part or all of the amount is set as the locked amount that the executed user has no right to dispose of, and the device includes:

The obtaining module 401 obtains the execution amount and the executed user identification;

The sending module 402 sends the execution amount and the executed user identification to the blockchain network; the blockchain network is responsible for managing the user's property account, so that each node in the blockchain network is based on consensus The mechanism publishes the execution transaction including the execution amount and the executed user ID to the blockchain, and based on the execution amount, debits the locked amount of the property account corresponding to the executed user ID.
