And S202, the first block chain node generates the tax closing certification and the related information of the first unit according to the tax closing request, wherein the related information is used for indicating that the first unit owns the tax closing certification.

The related information includes information of the first unit and information of the tax completion certification (for example, the information may be a tax completion certification voucher number), and when the first block link point sends the related information to other nodes in the block chain, the other nodes may determine the information of the first unit and the information of the tax completion certification according to the related information.

S203, the first block link links the related information of the first unit to the block chain.

Specifically, the purpose of the tax closing certification can be included in the tax closing request; or the first unit can send the purpose of the tax completion certification to the first block link point, the first block link point determines a second block link node according to the purpose of the tax completion certification, the first block link node initiates an asset transfer to the account address of the second block link according to the account address corresponding to the first block link node, and the relevant information of the first unit is added to the remark information of the transfer; the account address can also be called a wallet address, and transaction transfer can be carried out between the account addresses in the blockchain. After the transfer is successful, the transfer is recorded on the block chain, when the second block chain node receives the right and interest application of the first unit, the information on the block chain can be inquired, whether the first unit has the information of the tax completion certificate and the tax completion certificate is determined according to the asset transfer of the first unit in the block chain and the related information, and then the related right and interest are handled. Specifically, the second block link point may determine the amount of transacted traffic according to the amount of transfer assets, or may determine the amount of transacted traffic according to the related information. For example, the tax bureau corresponds to a first block chain node, the building part corresponds to a second block chain node, the first block chain node corresponds to a first account address, and the second block chain node corresponds to a second account address; the first block chain link point determines that the duty completion certificate is used for applying for a public rental house by using the duty completion certificate, and then determines a second node corresponding to the building part; the first block link point determines that the tax in the tax completion certificate of the first unit is 40 ten thousand yuan, and sets that 1 token is transferred to each 10 ten thousand yuan, then the first block link node transfers 4 tokens to the second account address by using the first account address after generating the tax completion certificate of the first unit, and adds related information of the first unit in the remark information of the transfer, wherein the related information comprises the identity information of the first unit and the information of the tax completion certificate, and the transfer is recorded on the block link after the transfer is successful; when a second block chain node of the building part receives an application of a first unit to a public rental house, the second block chain node searches the transfer transaction related to the first unit in the block chain and obtains remark information of the transfer transaction; the establishment department can set the application amount of the rights and interests according to specific conditions, specifically comprising the conversion relation between the tax and the rights and the direct proportion relation between the tax and the rights and interests; specifically, the building department may set that one set of public rental houses can be applied for every 10 ten thousand dollar tax fund or one set of public rental houses can be applied for every 1 token, and the second block link node may determine that the first unit can apply for 4 sets of public rental houses according to 4 tokens or 40 ten thousand dollars of tax fund transferred, and complete the handling of the related rights and interests.

S204, the first block chain node receives a tax refund request of the first unit.

Specifically, the first unit can send a tax refund request to the first block link point through the electronic device.

S205, the first block link point determines the use of the tax closing certification.

When the first unit uses the finalization certification, the second block chain node transfers an asset to the first block chain link point, and the asset is recorded in the block chain, so that the first block chain link point only needs to search whether the transfer record of the block chain comprises the relevant first unit, and the transfer record is that the second block chain node transfers to the first block chain link point, if yes, the finalization certification is determined to be used, and otherwise, the finalization certification is not used.

And S206, the first block link point executes tax refund operation according to the use condition of the tax completed certificate.

In one possible embodiment, the uplink of the first unit of related information to the block chain includes: determining a target account on the blockchain according to the tax completion request; and transferring a first quantity of assets to the target account by using the identity of the original account, wherein the remark information of the first quantity of assets comprises related information of a first unit, and the original account is an account corresponding to the first block chain node on the block chain.

The method comprises the steps that a target account is an account corresponding to a link point of a second block on a block chain, an original account transfers a first amount of assets to the target account, the transfer is carried out from an account address of the original account (the account address can be also called as a wallet address) to the account address of the target account, and the transfer amount is the first amount. Wherein the first number is a positive integer. The method comprises the steps that a first amount of assets are transferred from an original account to a target account and are recorded on a block chain, so that each node in the block chain can obtain transfer records and related information from the original account to the target account, and further, it is determined that a current first unit has a tax closing certificate, and the tax closing certificate is used for obtaining rights and interests corresponding to the target account, for example, a department corresponding to the target account is a building department, and the rights and interests corresponding to the building department are public rental houses or talent houses, so that the tax closing certificate is used for obtaining the public rental houses or talent houses, and the rights and interests managed by the building department are waited. The first quantity is proportional to the amount of rights and interests that the first unit can apply for, for example, if the department corresponding to the target account is a building department, the larger the first quantity is, the more public rental houses and talent houses the first unit can apply for in the building department.

In one possible embodiment, determining the use of the tax closing certificate comprises: acquiring at least one asset transferred from a target account to an original account, wherein each asset in the at least one asset comprises remark information; detecting whether the remark information comprises associated information of a first unit, wherein the associated information indicates that the first unit has a first right; if yes, the use condition of the tax completion certificate is used; if not, the use condition of the tax closing certification is not used.

The remark information corresponding to each transfer in at least one asset comprises information of an associated unit; such as transfers associated with a first unit, transfers associated with a second unit, etc.

When the target account transacts related rights and interests according to the tax completion certificates of different users, the rights and interests transaction of each user initiates a transfer from the target account to the original account, and the transfer is recorded on the block chain. Therefore, when determining the use condition of the tax completion certificate of the first unit, the first block chain node only needs to query the transfer record of the target account to the original account and the remark information of the transfer record on the block chain, and then the use condition of the tax completion certificate of the first unit can be determined.

And if the use condition of the tax closing certification is not used, executing tax refunding operation aiming at the first unit.

In one possible embodiment, the usage of the tax closing certification is used, and the tax refund operation is performed according to the usage of the tax closing certification, including: transferring a second quantity of assets to the target account by the identity of the original account, wherein the quantity of the second quantity of assets is the same as the quantity of the first assets in the at least one asset, and the remark information of the first assets comprises the association information of a first unit; receiving a third quantity of assets transferred from the target account by using the identity of the original account, wherein the remark information of the third quantity of assets comprises updated associated information of the first unit, and the updated associated information of the first unit represents that the first unit returns the first right; verifying the updated association information of the first unit; and if the verification result is that the first unit returns the first right, transacting the tax refund business of the first unit.

After the first blockchain node transfers a second amount of assets to the target account in the identity of the original account, and before receiving a third amount of assets transferred from the target account in the identity of the original account, the method further comprises the following steps: and the second block chain link point recovers the rights issued to the first unit and updates the associated information of the first unit, and then the second block chain node transfers a third amount of assets to the original account of the first block chain node in the identity of the target account and adds the updated associated information in the remark information of the assets. The first number, the second number and the third number may be the same or different from each other in the embodiment of the present invention, and need to be adjusted according to a specific application scenario of the embodiment of the present invention.

In one possible embodiment, after receiving a request to refund a tax for a first unit; before determining the use case of the tax closing certification, the method further comprises: detecting whether there is a proof of completion of the first unit; it is determined that there is a tax closing proof for the first unit.

After generating the first unit of the proof of completion of duties, the first blockchain node transfers a first amount of assets to the target account in the identity of the primary account, and the transfer record is recorded on the blockchain, so that the first blockchain node detects whether the first unit of the proof of completion of duties exists: inquiring transfer records in the block chain, judging whether transfer records related to a first unit exist according to information of the transfer records, and if the transfer records related to the first unit exist, determining that a tax completion certificate of the first unit exists; if there is no transfer record of the first unit, it is determined that there is no proofs of completion of the first unit.

In one possible embodiment, the close tax request includes attribute information, and after determining a target account on the blockchain according to the close tax request and before transferring a first amount of assets to the target account in the identity of the original account, the method further includes: inquiring a transaction record between the primary account and the target account in the blockchain; determining the resource allocation amount of a first institution corresponding to the target account according to the transaction record; acquiring the total amount of resources of the first mechanism; determining the ratio of the resource allocation amount to the total resource amount; if the ratio is smaller than or equal to a preset threshold value, determining the first quantity according to the tax payment amount in the tax payment certification; and if the ratio is larger than the preset threshold, determining the first quantity according to the attribute information and the tax payment amount.

When any unit applying the tax completion certification to the tax bureau obtains the tax completion certification and applies the corresponding rights and interests to the first mechanism by the tax completion certification, the first mechanism allocates the rights and interests to the unit, meanwhile, corresponding transfer is initiated to the original account on the block chain by the identity of the target account, and the value of the transfer is in direct proportion to the amount of the allocated rights and interests; thus, the first blockchain link point may query transaction records (and transfer records) between the primary account and the target account in the blockchain; and then determining the amount of resources currently allocated by the first organization according to the transaction record.

Wherein obtaining the total amount of resources of the first mechanism comprises: the first block chain node sends request information for acquiring the total amount of the resources to the original account by using the target account; then receiving the total amount of resources in the current period sent by the original account; specifically, the duration of the period may be set by the user of the primary account, for example, the period may be a natural day, a natural week or a natural month. The first block link point may determine the amount of resources that have been allocated in the current period.

If the ratio is less than or equal to a preset threshold, determining the first quantity according to the tax payment amount in the tax payment certification, specifically, storing a corresponding relation between the interval and the quantity of the tax payment amount in a first block chain; for example, the interval of paying tax amount corresponds to the quantity A; b, paying tax amount intervals corresponding to the quantity B; c, paying tax amount interval, corresponding to C quantity; if the tax payment amount proved by tax completion is in the interval of the A tax payment amount, the first amount is equal to the A amount.

In an actual application scenario, the taxpayer may be an individual or a company, the individual has different professions, and the properties of the company may be different, so that the property and attribute information of the individual profession or the company in the embodiment of the present invention; if the ratio is larger than the preset threshold value, inquiring a preset matching relation according to the attribute information to obtain a coefficient value corresponding to the attribute information, wherein the coefficient value is a numerical value larger than 0 and smaller than 1; after determining the corresponding quantity according to the tax payment amount, multiplying the quantity by the coefficient value to obtain a first quantity; for example, if the tax payment amount of the tax closing certification is in the interval of the A tax payment amount, the first quantity is equal to the product of the A quantity and the coefficient value.
