It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a block chain-based electronic equity transaction method, including:
s101, determining a blockchain platform which is created in advance based on a blockchain framework, wherein nodes in the blockchain platform comprise a plurality of users.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform created based on the blockchain framework may first be determined. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
In the transaction process of the electronic rights and interests, a plurality of users are required to participate in the transaction process, so that the plurality of users participating in the transaction can be deployed in the blockchain platform as nodes. Of course, the user may act as a seller or purchaser with different identities during different transactions.
And S102, receiving selling information which is sent by a first user and represents that the electronic rights owned by the first user are sold, and writing the selling information into the block chain platform, wherein the electronic rights comprise at least one of a red packet, a coupon, a credit card right and a digital service.
When the user wants to take the electronic right, sale information indicating that the electronic right owned by the user is sold can be transmitted. For convenience of description, the user is referred to as a first user. The electronic rights may include at least one of a red packet, a coupon, a credit card right, and a digital service, and the digital service refers to some digital services, such as a web lesson purchased on the network, a network service, and the like, which are not described herein again.
S103, receiving purchase information aiming at the electronic rights and sent by a second user, and writing the purchase information into the block chain platform.
And S104, after the second user carries out payment, writing payment information into the block chain platform.
After a first user writes sales information into the blockchain platform, if a user wants to make a purchase, purchase information indicating that the user wants to purchase an electronic interest may be sent and then written into the blockchain platform, where the user may be referred to as a second user. After the second user makes a payment, the payment information can be written into the blockchain platform, and at this time, the transaction process of the electronic right is completed.
In one embodiment, if it is determined that the first user is fraudulent, the first user may be penalized and then written into the blockchain platform. Wherein the penalties may include: tokens, credits, permissions in the blockchain platform, priority when writing data to the blockchain platform, storage space in the blockchain platform, no sale allowed for a preset duration, etc.
Specifically, the fraudulent behavior may include: the electronic interest cannot be used, there is a false description of the use limit or value of the electronic interest in the sales information, and there is no description of the use limit of the electronic interest in the sales information.
The electronic interest is not available, either due to expiration or a counterfeit electronic interest. The limits in the false description may include date limits, amount limits, people number limits, etc., and the value may include the value corresponding to itself. The lack of a description may mean that some necessary usage restrictions are not described, resulting in misleading consumers.
In one embodiment, after the transaction is completed, the second user may also send a usage rating for the electronic right, which is then written into the blockchain platform. After the usage evaluation indicates that the second user has used up the electronic right, the form of the electronic right and/or the evaluation of the first user may be a text, a picture, a voice, a video, a score, and the like, which is not limited herein. By setting the feedback mode, the first user can be more careful when selling the electronic rights and also provide certain reference for other buyers.
In one embodiment, the nodes in the blockchain platform further include issuers to which electronic benefits correspond. For example, if a coupon, the issuer may be the business that issued the coupon. In real life, there are electronic rights that are bound to the identity of the first user in the issuer's server, and if the transaction is conducted directly, the issuer's server may not be able to make timely changes. The issuing party is used as a node and deployed in the block chain platform, after the second user pays, the issuing party can determine that the electronic right is bound with the identity of the first user, the identity can be unbound by the issuing party, then the identity binding between the electronic right and the second user is established, and the reestablished identity binding is written into the block chain platform, so that the block chain platform is very convenient.
In one embodiment, after the first user sends the sale information, it may be determined whether the electronic right has a lifespan and a current time. If the time length between the current time and the service life is lower than the preset threshold value, the electronic right is indicated to reach the service life soon, at this time, a prompt can be given to the first user, and the prompt is written into the block chain platform, so that the first user can have a basis when describing or making a selling price.
In one embodiment, the corresponding intelligent contracts may also be generated in advance and deployed in the blockchain platform. The smart contract includes at least one of sales information, purchase information, and payment information. The intelligent contract is used for writing the selling information into the block chain platform after the selling information is received; or after the purchase information is received, writing the purchase information into the block chain platform; or after the second user carries out payment, the payment information is written into the block chain platform. Since the intelligent contracts on the blockchain platform are public, each node can check whether the intelligent contracts are in accordance with the preset agreement or not and deploy the intelligent contracts on the own node. And each user can inquire the intelligent contract through a corresponding way, so that the degree of automation of the transaction is improved, and the trust degree of each user is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
In one embodiment, a digital object Unique Identifier (DOI) for the electronic rights may also be generated, such as a two-dimensional code, barcode, etc., to facilitate more convenient querying of the electronic rights by the respective user. Taking the two-dimensional code as an example, each user can access data associated with the electronic right, such as sales information, purchase information, payment information, and the like, by scanning the two-dimensional code corresponding to the electronic right. Once the electronic rights and interests have problems, the second user can trace the electronic rights and interests by scanning the two-dimensional code at any time so as to find the problems, and the method is very convenient.
