Description

Method for dyeing bill based on UTXO

Technical Field

The invention relates to the technical field of use of a dyeing bill realized based on UTXO, in particular to a dyeing bill method realized based on UTXO.

Background

As the earliest occurring cryptocurrency, Bitcoin uses the UTXO model as its underlying stored data structure, which is called the unused Transaction output, i.e. the unused Transaction output.

In bitjoin and other cryptocurrencies that use the UTXO model, the balance in an "account" is not represented by a number, but is made up of all UTXOs associated with the current "account" in the current blockchain network.

The data model for UTXO is as follows:

according to the transaction model of the UTXO, any one of the persons in the block chain has the right to spend the possessed UTXO, and any one of the persons has the right to receive the UTXO.

At present, in an actual business model, sales promotion manner, Chinese-stroke-group preference, Chinese-stroke-left welfare oriented bills and the like are common scenes in which the cash-substituting bills can be used, and receiving merchants or organizations of the cash-substituting bills have specificity. The traditional block chain model is public-oriented open transaction and cannot meet the actual requirement of a limited bill.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a method for dyeing a bill based on UTXO, which solves the problems that the existing method for dyeing a bill based on UTXO is inconvenient to satisfy the traditional government affairs and business scenes for block chain encryption currency, and the inconvenient traceability of the dyeing bill based on UTXO is inconvenient, and the role of a payee is not introduced for the inconvenient supervision.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: the invention relates to a method for dyeing bills based on UTXO (unified extensible markup language), which is used for expanding dyeing information based on a data structure model of UTXO and is used for bill circulation scenes. The UTXO is part of a transaction, which is based on the UTXO model and consists of two parts, input (vin) and output (vout):

the traditional UTXO data model solves the problems of double flowers, traceability and the like, and is used like cash in reality.

In order to enable UTXO-based blockchain transaction to support ticketing, we add dyeing data, i.e., an extended color field, to the UTXO data model of the blockchain, where the color includes color value left-falling character verification information and the like:

preferably, the user makes a payment request to the merchant using the ticket, and the payment request is then validated by the validation service.

Preferably, the authentication service device sends a payment request initiated by a user to a role authority authentication center, and the role authentication center authenticates the authority of the merchant.

Preferably, the role authority verification center verifies whether the dyeing bill of the merchant meets the requirement, and if so, the role authority verification center indicates that the transaction is successful.

(III) advantageous effects

The invention provides a method for dyeing a bill based on UTXO. The method has the following beneficial effects:

(1) according to the method for dyeing the bill based on the UTXO, a USER 1(USER _1) goes to a common store (SHOP _1) to buy a commodity with the price of 3, 1 conventional UTXO (UTXO _ COMM _10) with the face value of 10 is arranged in ADDR _ U _1, USER _1 is signed and verified by a service, UTXO _ COMM _10 respectively costs 3 to ADDR _ S _1 of SHOP _1, and 7 to ADDR _ U _1 of USER _ 1.

(2) The method for dyeing the bill based on the UTXO is characterized in that a USER USER _2 goes to an electric appliance store (R2) in a county and city to buy a microwave oven, UTXO _ COLOR _3C is used during payment, a verification service verifies a role value required by dyeing currency UTXO _ COLOR _3C after receiving a payment request, a role authority verification center (see' a multi-chain USER role management and verification method based on a block chain) is requested to verify the authority of a payee R2, if the authority is met, the verification service agrees to sign the transaction, otherwise the transaction fails, the UTXO-based transaction can be traced back in the block chain, but the transaction is transparent, anyone can participate in the transaction, and the transaction is high-frequency and multi-dimensional transaction and is difficult to accept at a supervision level, the dyeing bill is added into the role verification of a payee, so that each expense of the bill can be easily brought into a supervision system, the user can not transfer the received bills to other people, and one user can not take the subsidies of multiple people to effectively supervise the funds such as poverty relief.

Drawings

FIG. 1 is a schematic view of a process for the consumption of dyed tickets.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-1, the present invention provides a technical solution: a method for dyeing bills based on UTXO comprises the following steps:

step 1, a user initiates a request for paying to a merchant by a dyeing bill;

step 2, acquiring the signature and role of the merchant;

step 3, verifying the authority of the merchant to a role authority verification center;

step 4, checking whether the role of the merchant meets the bill requirement;

and 5, if the verification is successful, sending verification service verification, and if the verification is failed, indicating that the payment is failed.

In this embodiment, the user makes a payment request to the merchant using the ticket, and then the payment request is verified by the verification service. The USER 1(USER _1) goes to the general SHOP (SHOP _1) to buy an item with a price of 3, ADDR _ U _1 has 1 regular UTXO (UTXO _ COMM _10) with a value of 10, USER _1 is signed and verified with the service, UTXO _ COMM _10 will cost 3 to address ADDR _ S _1 of SHOP _1 and 7 to address ADDR _ U _1 of USER _1, respectively.

In this embodiment, the verification service device sends a payment request initiated by a user to a role authorization verification center, and the role verification center verifies the authorization of a merchant. The USER USER _2 goes to an electric appliance store (R2) in county and city to buy a microwave oven, uses UTXO _ COLOR _3C during payment, verifies the role dyeing value required by the dyeing currency UTXO _ COLOR _3C after receiving a payment request by a verification service, requests a role authority verification center (see 'a block chain-based multi-chain USER role management and verification method') to verify the authority of a payee merchant R2, and if the authority is met, the verification service agrees to sign transaction, otherwise the transaction fails.

In this embodiment, the role authority verification center verifies whether the dyed ticket of the merchant meets the requirements, and if so, the role authority verification center indicates that the transaction is successful. The transaction based on the UTXO can be traced in a block chain, but the transaction is transparent, anyone can participate in the transaction, the transaction with high frequency and multiple dimensions is difficult to accept in a supervision aspect, the dyed bill is added into the role verification of a payee, so that each cost of the bill can be easily brought into a supervision system, a user cannot transfer the received bill to other people, one user cannot take the subsidy of multiple people, and funds such as poverty relief are effectively supervised.

In operation, the UTXO dyed ticket usage scenario herein is exemplified by grain subsidies and home appliance rural subsidies for government precision poverty relief, such as the tickets having a grain and oil ticket (T1) a chinese-to-home appliance ticket (T2), a grocery store (SHOP _1) a chinese-to-county-city a grain and oil store (R1) a chinese-to-county-city an electrical store (R2), a USER 1(USER _1) a chinese-to-county-city USER 2(USER _2), a USER and a store (a general store and a store supporting the use of precision poverty relief tickets) in a blockchain are addresses in a blockchain; one user may have either a conventional UTXO or a dyed UTXO; all merchants can receive the conventional UTXO, only merchants with specific roles can receive the UTXO with corresponding dyeing authority, and the merchants with dyeing bill payment authority need to perform role setting through a role authority verification center (see a block chain-based multi-chain user role management and verification method for details).

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
