Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.

To clearly describe the technical solution of the embodiment, an application class system architecture diagram based on a block chain is first described. Fig. 1 is a schematic architecture diagram of an electronic bill transfer system based on a block chain according to an embodiment of the present invention. Referring to fig. 1, the system includes a blockchain network for storing and managing electronic tickets and their related information, which may include at least lightweight nodes. The lightweight node is used as a node in the blockchain network, can directly send a request to the blockchain, and receives transaction data fed back by the blockchain network or other blockchain nodes. A certain node in the blockchain network may serve as a service application platform, such as an electronic ticket service platform, to provide service services for users in the blockchain network. The block chain network can also comprise user nodes, the user nodes can be used as channels for communication between the block chain and external equipment, can receive information sent by the external equipment, generate transaction processing requests and transmit the transaction processing requests to the block chain network, and transmit information inquired from the block chain to the external equipment; the user node can also be in communication connection with a service application platform of the non-block chain node, and the service application platform is in communication connection with external equipment. Meanwhile, the user node is used as a node in the block chain network, and can process the transaction processing request in the block chain.

In particular, a lightweight node is a blockchain network node that does not store or store portions of block data and transaction data. The lightweight node configured in the terminal device 210 in fig. 2 provides an upper layer interactive interface for data interaction with the application client through the upper layer interactive interface. The lightweight node can realize functions through software and is integrated in an operating system. The upper layer interactive interface can be an interface for the lightweight node to directly interact with the client, and can also be an interface configured through an operating system.

The upper layer interactive interface can obtain client interactive data from the application program client. Illustratively, the client interaction data may be corresponding functional requirement data generated by triggering the functional options of the application client by the user; it is also possible that the application client receives other applications in the terminal device 210 or receives the function requirement data transmitted by other terminal devices. Functional requirement data can be understood as control commands relating to the blockchain network and as transaction requests relating to entity data.

The lightweight node configured in the terminal device 210 further provides a network interaction interface for performing data interaction with other blockchain network nodes 220 in the blockchain network through the network interaction interface.

Wherein the client interaction data is associated with blockchain network node interaction data. Illustratively, the blockchain network node interaction data may be client interaction data; the client interactive data can also be converted into client interactive data associated data in a form which can be transmitted by a block chain network; but also data fed back by the blockchain network received based on the client interaction data or client interaction data associated data.

It should be noted that the lightweight node may be loaded in the operating system of the terminal device 210, so as to directly drive hardware, such as a CPU, a storage device, a network communication device, and the like, through a driver of the terminal device 210 to implement a corresponding function; the lightweight node may also be installed in the terminal device 210 as an independent third-party application, and the corresponding function is implemented through the operation of the third-party application.

The lightweight node is provided with the deployment data of the block chain, so that the lightweight node can participate in the transaction request interaction process of the block chain, but not store all block data, and when the lightweight node needs to inquire the transaction data in the block, the lightweight node can acquire the transaction data from other nodes in real time and verify the transaction data in a set mode.

It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Example one

Fig. 3 is a flowchart of an electronic bill transfer method based on a blockchain according to an embodiment of the present invention, where this embodiment is applicable to an online transfer situation of an electronic bill, and the method is executed by a blockchain link node, and may be executed by an electronic bill transfer apparatus based on a blockchain configured at a blockchain node, where the apparatus may be implemented in a software and/or hardware manner, and is preferably an electronic device carrying the blockchain node.

The method specifically comprises the following steps:

s310, verifying the validity of the received bill transfer transaction request; wherein the ticket transfer transaction request is generated upon monitoring an electronic ticket transfer event of the first user.

In an embodiment of the present invention, the first user refers to a user who has purchased an electronic ticket and performs ticket transfer. The ticket transfer transaction request refers to a request for initiating a ticket transfer transaction to the blockchain network, and the ticket transfer transaction request is generated by a service end used by the first user. Specifically, the service end is a platform for providing an electronic ticketing service, and may be a client installed on a user terminal device and interacting with a user, and correspondingly, the user terminal device is used as a lightweight node in a block chain network; or a background server of a client interacted by a user, wherein the server is used as a service application platform in a block chain node mode.

The first user has a blockchain account, and the user does not have a strict corresponding relation with a node in the blockchain network. That is, one user may correspond to several nodes, one node may also bear several users, and there is no fixed corresponding relationship between nodes and users. The user can manage the account data of the user through the public key and the private key of the user, and correspondingly, the bill transfer transaction request at least can include the first user address, namely the information of the blockchain account of the first user, the transferred electronic bill, the transferred quantity, the transferred price and the like.

In this embodiment, the blockchain account of the first user writes the electronic bill to be transferred, and when the business end to which the first user belongs monitors the electronic bill transfer requirement of the first user, a bill transfer transaction request is generated and transmitted to the blockchain network. Correspondingly, other nodes in the block chain network receive the ticket transfer transaction request broadcast in the block chain network, and can perform validity verification on the ticket transfer transaction request.

Specifically, different from the conventional verification method of the block link point for the transaction processing request, the block link point in this embodiment may directly verify the validity of the ticket transfer transaction request according to the electronic ticket voucher purchasing data stored in the block chain, that is, the electronic ticket to be transferred by the first user is used as a digital asset, and it is verified whether the electronic ticket to be transferred actually exists in the block chain account of the first user, that is, whether the electronic ticket exists is verified. The block chain node is prevented from calculating the account information of the first user block chain again according to the bill transfer transaction request, and the process of comparing the calculation result with the information in the received bill transfer transaction request is avoided, but whether the electronic bill exists or not is directly verified. If the verification exists, the validity of the ticket transfer transaction and the authenticity of the electronic bill required to be transferred are verified.

Illustratively, a block chain node receiving a bill transfer transaction request may invoke an authentication intelligent contract to determine whether an electronic bill to be transferred exists in a block chain account of a first user; and if so, determining that the bill transfer transaction request is valid. And if the bill transfer transaction request is invalid, rejecting the bill transfer transaction request, and writing the failed transfer record of the first user as transaction data into the block chain.

Correspondingly, before the validity verification of the received ticket transfer transaction request, the purchase process of the electronic ticket by the first user is also included. Specifically, when monitoring a first ticket purchasing event of the first user, the service end to which the first user belongs generates a ticket issuing transaction request, and transmits the ticket issuing transaction request to the block chain network. Correspondingly, other nodes in the blockchain network receive the ticketing transaction request broadcast in the blockchain network, call the ticketing intelligent contract to generate an electronic bill, and write the generated electronic bill into the blockchain account of the first user. And writing the purchase voucher data of the electronic bill generated according to the first user information into the block chain as transaction data.

And S320, if the bill transfer transaction request is valid, generating a bill transfer notice, and sending the bill transfer notice to other user nodes in the blockchain network for other users to obtain the transfer information of the electronic bills.

In the embodiment of the invention, the block chain node point which receives the bill transfer transaction request verifies the validity of the bill transfer transaction request, and if the bill transfer transaction request is valid, that is, the electronic bill to be transferred exists in the block chain account of the first user, and the validity of the bill transfer transaction and the authenticity of the electronic bill to be transferred are verified, the block chain node point may generate a bill transfer notification for notifying other users in the block chain network of knowing the transfer information of the electronic bill.

In particular, the validation of validity and the generation of the notification may be performed by any blockchain node participating in the blockchain network, preferably a blockchain generation node. For example, the blockchain generation node may generate a ticket transfer notification when the ticket transfer transaction request is validated, and transmit the ticket transfer notification into the blockchain network, so that other nodes in the blockchain network terminate validation of the ticket transfer transaction request and receive the ticket transfer notification. In this embodiment, the node generating the ticket transfer notification is not limited, the validation of the ticket transfer transaction request may be performed by an intelligent contract, and the node generating the ticket transfer notification may be determined by a consensus mechanism.

In this embodiment, the other user nodes may be lightweight nodes, for example, are installed at a client of the user terminal, and show the assignment information in the ticket assignment notification in a client page; or the other user nodes can be servers of the service application platform, and the servers push the transfer information in the bill transfer notification to the client of each user in the form of messages or notifications to be displayed. Wherein, the bill transfer notice at least comprises transferred electronic bills, transferred quantity, transfer price and other transfer information. Accordingly, after receiving the transfer information of the electronic ticket, other users in the blockchain network can decide whether to purchase the electronic ticket transferred in the blockchain.

S330, in response to the received bill granting transaction request, writing the electronic bill into the blockchain account of the second user; wherein the ticket granted transaction request is generated upon detection of an electronic ticket granted event of the second user.

In an embodiment of the present invention, the second user is a user who purchases an electronic ticket transferred in the blockchain network. A ticket-granted transaction request refers to a request to initiate a ticket-granted transaction to the blockchain network, the ticket-granted transaction request being generated by a service used by the second user. The service end used by the second user may be a client or a server of the service application platform, which is the same as the service end used by the first user. The ticket grant transaction request at least includes information of the second user address, i.e. the blockchain account of the second user, the granted electronic ticket, the granted amount, the paid element, and the like.

In this embodiment, when the service end to which the second user belongs monitors an electronic ticket granting event of the second user, a ticket granting transaction request of the second user is generated and transmitted to the blockchain network. Correspondingly, other nodes in the blockchain network receive the request of the ticket granting transaction broadcast in the blockchain network and directly write the electronic ticket into the blockchain account of the second user. For example, the blockchain generation node directly responds to the request of the ticket-granted transaction, writes the electronic ticket granted by the second user into the blockchain account of the second user, and clears the electronic ticket transferred from the blockchain account of the first user. The electronic ticket to be transferred may be a brand new electronic ticket purchased by the first user, or may be a second-hand electronic ticket that is given by the first user in the blockchain network.

In the embodiment, the electronic ticket associated with the ticket transfer transaction request which is validated effectively is directly written into the blockchain account of the second user, so that the second user purchases the electronic ticket from the first user after the blockchain is validated effectively, and the first user sends the electronic ticket to the second user, namely, multiple interactions between the second user and the first user are avoided. The electronic bill is not required to be sent to the transferee by the transferor, and the transfer market of the electronic bill is standardized.

In this embodiment, for traceability of the electronic ticket, transfer voucher data of the electronic ticket is generated according to the first user information and the second user information, and the transfer voucher data of the electronic ticket is written into the block chain as transaction data.

According to the technical scheme of the embodiment, the block chain link point verifies the validity of the received bill transfer transaction request initiated by the service end to which the first user belongs, if the verification is valid, a bill transfer notice is generated, and the bill transfer notice is sent to other user nodes in the block chain network, so that other users can obtain the transfer information of the electronic bill, and therefore the bill transfer transaction request initiated by the service end to which the second user belongs is received, and the electronic bill is directly written into the block chain account of the second user. According to the method and the device for electronic bill transfer, the transferred electronic bill information is notified to the user in the blockchain network through validity verification of the bill transfer transaction request, the electronic bill can be directly transferred to the blockchain account of the transferee as a digital asset when the user is granted, the electronic bill is truly transferred to the blockchain account of the transferee, repeated operation that the transferor sends the electronic bill to the transferee again after issuing the bill transfer transaction request is avoided, operation of the transferor is simplified, and authenticity, safety and efficiency of electronic bill transfer are improved.

Example two

On the basis of the first embodiment, the embodiment provides a preferred embodiment of the block chain-based electronic bill transfer method, which can link the data of the purchasing and transferring links of the electronic bill, thereby realizing the traceability of the electronic bill and facilitating the user to obtain the authenticity of the electronic bill. Fig. 4 is a flowchart of an electronic bill transfer method based on a block chain according to a second embodiment of the present invention, and as shown in fig. 4, the method specifically includes the following steps:

s410, receiving a ticket issuing transaction request generated when a business end monitors a first ticket purchasing event of a first user; and calling the intelligent contract for drawing the ticket to generate an electronic ticket, and writing the generated electronic ticket into the blockchain account of the first user.

In the embodiment of the invention, the service end is a platform for providing the electronic ticket service, and can be a client end which is arranged on the user terminal equipment and interacts with a user, and correspondingly, the user terminal equipment is used as a lightweight node in a block chain network; or a background server of a client interacted by a user, wherein the server is used as a service application platform in a block chain node mode.

In this embodiment, the first user first performs the purchasing action of the electronic ticket before owning or reselling the electronic ticket, that is, the first user currently refers to the user who is purchasing the electronic ticket. The ticket making transaction request refers to a request of a user for initiating a transaction for purchasing an electronic ticket to the blockchain network.

Specifically, when the first user purchases a ticket for the first time, if the service end to which the first user belongs monitors the first ticket purchase event according to the interaction behavior of the first user, for example, the behavior of the first user controlling an electronic ticket purchase page loaded by the client, or the behavior of the first user submitting purchase information, etc., a ticket issue transaction request is generated and transmitted to the blockchain network. Accordingly, other nodes in the blockchain network may receive the ticketing transaction request transmitted in the blockchain network. The ticketing transaction request can include ticket information such as a blockchain account of the first user, a designated use place of the electronic ticket to be ticketed, an applicable crowd type and the like.

In this embodiment, the intelligent contract for drawing tickets is configured in the block chain network in advance, and is used for limiting the ticket drawing rule of the electronic ticket and processing the ticket drawing transaction request. After receiving the request of the ticketing transaction, the blockchain node calls a ticketing intelligent contract, generates an electronic bill purchased by the first user according to a ticketing rule of the electronic bill in the ticketing intelligent contract, for example, generates bill information such as a unique bill number and a valid period of a use place specified by the electronic bill, and writes the electronic bill into a blockchain account of the first user as a digital asset of the first user.

And S420, writing the purchase voucher data of the electronic bill generated according to the first user information into the block chain as transaction data.

In the embodiment of the invention, each electronic bill can be used as an independent digital asset based on the property of the block chain, and the transaction process of the asset needs a full-flow chain. Correspondingly, the voucher purchasing data of the electronic bill is generated according to the first user information, and the voucher purchasing data can comprise information of a designated use place of the electronic bill, a unique ticket number of the designated use place, an applicable crowd type, an effective period, a transaction price, a transaction time, a first user block chain account and the like. Therefore, the data of the purchase voucher is written into the block chain as transaction data, and the electronic bill can be traced according to the data of the purchase voucher stored in the block chain, so that the real safety of the electronic bill is ensured, and the information of the electronic bill is prevented from being tampered.

S430, verifying the validity of the received bill transfer transaction request; wherein the ticket transfer transaction request is generated upon monitoring an electronic ticket transfer event of the first user.

In the embodiment of the invention, the blockchain account of the first user writes the electronic bill to be transferred, and when the business terminal to which the first user belongs monitors the electronic bill transfer requirement of the first user, a bill transfer transaction request is generated and transmitted to the blockchain network. Correspondingly, other nodes in the block chain network receive the ticket transfer transaction request broadcast in the block chain network, and can perform validity verification on the ticket transfer transaction request.

Optionally, invoking an authentication intelligent contract, and determining whether an electronic bill to be transferred exists in the blockchain account of the first user; and if so, determining that the bill transfer transaction request is valid.

In this embodiment, the verification intelligent contract is a verification rule configured in advance in the blockchain network and used for limiting the validity of the ticket transfer transaction request, and verifies the authenticity of whether the transfer user associated with the ticket transfer transaction request has the electronic ticket to be transferred. And after receiving the bill transfer transaction request, the blockchain node calls a verification intelligent contract, and verifies whether the electronic bill to be transferred exists in the blockchain account of the first user according to a verification rule for verifying the validity of the bill transfer transaction request in the verification intelligent contract. And if the electronic bill to be transferred exists in the blockchain account of the first user, determining that the bill transfer transaction request is valid.

Optionally, if the bill transfer transaction request is invalid, the bill transfer transaction request is rejected, and the failed transfer record of the first user is written into the block chain as transaction data.

In this embodiment, if it is verified that the electronic ticket to be transferred does not exist in the blockchain account of the first user, it is determined that the ticket transfer transaction request is invalid. For ticket transfer transaction requests that are validated to be invalid, the block chain node may reject the ticket transfer transaction request. And determining a failed transfer record of the first user according to the first user information and the invalid bill transfer transaction request, and writing the failed transfer record serving as transaction data into a block chain. The transfer failure record may include the blockchain account of the first user, invalid electronic ticket information, transfer price, transfer failure time, and other information.

In the embodiment, through the cochain processing of the failed transfer record, not only is the authenticity of electronic bill transfer ensured, but also the failed transfer label can be added to the first user according to the failed transfer record, or the electronic bill transfer credit degree of the first user is reduced, so that when the first user initiates the bill transfer transaction request again, the bill transfer transaction request of the first user is emphatically verified, even the bill transfer transaction request of the first user is directly rejected, and the invalid application of the first user on the amount is avoided.

And S440, if the bill transfer transaction request is valid, generating a bill transfer notice, and sending the bill transfer notice to other user nodes in the blockchain network for other users to obtain the transfer information of the electronic bills.
