It should be understood that the type and number of computer devices and networks in FIG. 1 are merely illustrative. There may be any type and number of computer devices and networks, as the implementation requires.
Fig. 2 is a schematic flowchart of a resource flow transaction method applied to a provider client according to an embodiment of the present invention, and as shown in fig. 2, the method is applied to the provider client, and the resource flow transaction process provided by the present disclosure is described as follows from the perspective of the provider client:
the method comprises the following steps:
s201: establishing an association with a requestor client through a blockchain server, providing a resource stream to the requestor client such that the requestor client receives and uses the resource stream.
S202: obtaining credential information representing a state of the requester client using the resource stream, sending the credential information to a blockchain server, and determining, by the blockchain server, a first numerical value based on the credential information, where the first numerical value is used to represent a numerical value added by the requester client to an account of a provider client.
It can be seen that the method shown in fig. 2 establishes an association with a corresponding requester client through the blockchain server before the transaction starts to perform the transaction, enables the blockchain server to supervise the transaction progress status by sending the credential information to the blockchain server during the transaction, and determines the transaction fee through the blockchain server after the transaction is ended so as to enable the requester client to perform payment. According to the method, the transaction of the resource flow is participated in by the blockchain server as a third party from beginning to end, and the blockchain server is any node in the blockchain network, and the action of any blockchain server is seen by other blockchain servers in the blockchain network, so that multi-party credible supervision on the transaction action of the resource flow is formed, the blockchain server in a requester, a provider or the blockchain network cannot cheat, and a fair transaction mode of the resource flow is realized.
As described above, the resource flow in the embodiments of the present disclosure refers to a resource that can be continuously and streamingly provided and consumed with usage, and may be, for example, one or more of a network traffic resource, a power resource, a computing resource, a designated data flow resource with real-time dynamics, and the like, without limitation.
In one embodiment of the present disclosure, operation S201 of the method shown in fig. 2 establishes an association with a requesting client through a blockchain server, and providing a resource flow to the requesting client includes: receiving transaction request information sent by a blockchain server, wherein the transaction request information comprises identification information of a requester client and a digital signature of the requester client, the transaction request information is sent to the blockchain server by the requester client, when the transaction request information is permitted, transaction permission information is sent to the blockchain server, the transaction permission information comprises the transaction request information and the digital signature of a provider client, and resource flow is started to be provided to the requester client.
According to the embodiment, after the requester client selects the provider client according to the self requirement, the transaction request information expressing the transaction requirement of the resource flow is sent to the provider client through the blockchain server, the provider client can judge whether to permit the transaction request information according to the self requirement, if the transaction request information is permitted, the corresponding transaction permission information is sent to the blockchain server, namely association between the requester client and the provider client is established, the transaction can be started, if the transaction request information is not permitted, subsequent processing can be omitted, namely association between the requester client and the provider client is not established, and the transaction cannot be carried out. The transaction request information carries a digital signature of a requester client for proving the authenticity of the transaction request information, and the blockchain server can forward the transaction request information to the provider client after verifying that the transaction request information is true based on the digital signature of the requester client, or the provider client can verify the authenticity of the transaction request information based on the digital signature of the requester client after receiving the transaction request information, and whether the transaction request information is permitted or not is considered after the transaction request information is verified to be true. The transaction approval information carries a digital signature of a provider client for proving authenticity of the transaction approval information, and the blockchain server may verify authenticity of the transaction approval information based on the digital signature of the provider client, or the blockchain server may verify authenticity of the transaction approval information collectively not only by the digital signature of the provider client but also by the digital signature of a requester client in the transaction request information carried in the transaction approval information.
Specifically, the digital signature of the requester client and/or the digital signature of the provider client may be formed by means of asymmetric encryption, for example,
specifically, in this embodiment, digital signatures of both transaction parties may be formed in an asymmetric encryption manner, for any requesting client, the requesting client corresponds to a unique key pair, and the key pair includes a public key and a private key, where the public key is public, that is, other requesting clients, each provider client, and/or each blockchain server may obtain the public key of the requesting client, and the private key is not public, and any other party cannot obtain the private key of the requesting client, and only the requesting client can use the private key by itself. Similarly, any provider client may have a dedicated key pair, and any blockchain server may have a dedicated key pair. The digital signature of the requester client in the transaction request information may be obtained by encrypting the transaction request information based on a private key of the requester client, and the blockchain server may verify the authenticity of the digital signature by using a public key of the requester client to prove the authenticity of the transaction request information. And/or the digital signature of the provider client in the transaction permission information may be obtained by encrypting the transaction permission information based on a private key of the provider client, and the blockchain server may verify the authenticity of the digital signature by using a public key of the provider client to prove the authenticity of the transaction permission information. In other embodiments, the two parties to the transaction may form their respective digital signatures in other manners, and any manner that can achieve the purpose of proving the authenticity of the sent information to a plurality of blockchain servers as third parties may be used, which is not limited herein.
Further, as an optional embodiment, the transaction request information sent by the requester client further includes a total amount of the expected used resource flow, and after the transaction request information is forwarded to the provider client by the blockchain server, the provider client may determine whether itself can meet the supply requirement according to the total amount of the expected used resource flow therein, i.e. as one of the references for determining whether to permit the transaction. That is, the operation S201 of establishing an association with the requester client through the blockchain server further includes: when the total amount of expected usage resource flow is not greater than the total amount of resource flow that can be provided, the transaction request information is granted.
In one embodiment of the present disclosure, the obtaining, by operation S202 of the method shown in fig. 2, credential information characterizing a state of the requesting client using the resource stream, and the sending the credential information to the blockchain server includes: and receiving the resource flow use certificate sent by the client side of the request party, judging that the resource flow used by the client side of the request party is finished if the resource flow use certificate is not received after the preset time is exceeded, and sending the received resource flow use certificate to the block chain server.
For example, the provider client receives a resource stream usage certificate sent by the requester client at preset time intervals, the resource stream usage certificate records information about usage states such as the number of currently used resource streams, and after receiving the resource stream usage certificate, if the resource stream usage certificate is not received after a preset time, the provider client indicates that the requester client has stopped using, the supply of the resource streams can be stopped, and the transaction fee is settled through the blockchain server.
Further, in order to improve the reliability of the credential information, the resource flow usage credential sent by the requestor client further includes, in addition to the information characterizing the resource flow usage state, a digital signature of the requestor client, where the digital signature is used to prove the authenticity of the resource flow usage credential, and then the sending, in operation S202, the received resource flow usage credential to the blockchain server further includes: and verifying the resource flow use certificate based on the digital signature of the client side of the requester, and if the verification is true, sending the resource flow use certificate to the block chain server. And/or the sending the received resource flow usage credential to the blockchain server in operation S202 further includes: and correspondingly sending the resource flow use certificate and the digital signature of the client side of the provider to the blockchain server, so that the blockchain server can verify the authenticity of the resource flow use certificate according to the digital signature of the client side of the provider and/or the digital signature of the client side of the requester. In the embodiment, the authenticity of the resource flow use certificate is proved by adding the digital signature of the requester client and the digital signature of the provider client to the resource flow use certificate, and only when the resource flow use certificate is authentic, the resource flow use certificate is considered to be valid, and the blockchain server can perform transaction settlement by using the resource flow use certificate.
It should be noted that the resource flow in the embodiment of the present disclosure refers to a resource that can be continuously and streamingly provided and consumed along with use, for example, the resource may be a network traffic resource, an electric power resource, a calculation power resource, a specified data stream resource with real-time dynamics, and the like, and various streamable consumable resources with such characteristics may be used as the resource flow in the embodiment of the present disclosure, which is not limited herein. Based on the above characteristics of the resource flow, the transaction of the resource flow is usually started when the resource flow is used, and ended when the resource flow is used, so that the transaction fee corresponding to the transaction of the resource flow is often obtained only after the transaction is ended, and the corresponding transaction fee is calculated according to the total usage amount of the resource flow.
Specifically, in this embodiment, the above-mentioned asymmetric encryption manner may also be adopted to form digital signatures of both transaction parties, for example, the requesting client encrypts the resource stream usage certificate based on its own private key to obtain the digital signature of the requesting client, the providing client encrypts the resource stream usage certificate and the digital signature of the requesting client based on its own private key to obtain the digital signature of the providing client, and the blockchain server may verify the authenticity of the digital signature of the requesting client and the digital signature of the providing client by using the public key of the requesting client and the public key of the providing client to prove the authenticity of the transaction request information.
By applying the embodiment shown in fig. 2 of the present invention, the transaction of the resource flow is participated in by the blockchain server as the third party from the beginning to the end, and because the blockchain server is any node in the blockchain network, the behavior of any blockchain server is witnessed by other blockchain servers in the blockchain network, so that multi-party credible supervision for the transaction behavior of the resource flow is formed, no matter whether the requester, the provider or the blockchain server in the blockchain network cannot cheat, the problem of cheating by any one or more parties of the requester and the provider in the resource flow transaction process can be at least partially solved, alleviated, inhibited, or even avoided, and a fair resource flow transaction mode is realized.
For ease of understanding, a specific application of the resource flow trading system to which embodiments of the present invention are applied is described below. In practical application, first, the requester client a searches for traffic sharing information sent by each provider client through a dedicated channel, where the traffic sharing information corresponds to the resource flow publishing information, and one or more kinds of information used for describing characteristics of the provided traffic, such as unit traffic price, total amount of the provided traffic, and type of the provided traffic, may be recorded in the traffic sharing information sent by each provider client, and the requester client a may select a suitable provider client according to its own needs. The dedicated channel used by the client a of the requester may be a local area network provided by the client of the provider and enabling the client a of the requester to be used for free at certain time, certain place and the like, and of course, the dedicated channel may be in other forms as long as the requirement of the client a of the requester for viewing the traffic sharing information can be temporarily met.
Then, after the requester client a selects the provider client B, transaction request information is generated, which includes: the identification information of the requestor client a, the identification information of the selected provider client B, the expected usage traffic total, and a second value representing the amount of the prepaid deposit, the second value corresponding to the value of the digital currency decremented from the account of the requestor client a, the requestor client a further generating a digital signature a1 of the requestor client a based on the generated transaction request information and the private key of the requestor client a, the digital signature a1 being appended to the generated transaction request information. The client a of the requester sends the transaction request information to a traffic sharing contract running in the blockchain server, and after the traffic sharing contract verifies that the transaction request information is true according to the public key and the digital signature a1 of the client a of the requester, sending the transaction request information to the provider client B, wherein the provider client B can determine whether to permit traffic sharing with respect to the requester client a according to information recorded in the transaction request information, and if the traffic sharing is permitted, the provider client B can generate a digital signature B1 of the provider client B based on the received transaction request information and a private key of the provider client B, the digital signature B1 is attached to the received transaction request message to form transaction approval message, which the provider client B sends to the traffic sharing contract indicating approval for traffic sharing and starts providing traffic to the requester client a.
The traffic sharing contract can store the received transaction permission information into the blockchain database corresponding to each blockchain server through the consensus verification of each blockchain server so as to obtain the joint supervision of multiple parties.
During the traffic sharing period, the requester client a periodically transmits to the provider client B traffic usage credentials corresponding to the above resource flow usage credentials, and each traffic usage credential records the total amount of traffic used by the requester client a from the start of usage to the time point corresponding to the traffic usage credential. The provider client B can know that the requester client a is still using the traffic each time the provider client B receives the traffic use credential, and when the provider client B does not receive the updated traffic use credential more than a predetermined time after receiving one traffic use credential, the provider client B can determine that the requester client a stops using the traffic, and the provider client B can stop providing the traffic to the requester client a and submit the last received traffic use credential to the traffic sharing contract. In this way, when the requester client a does not send traffic usage credentials to the provider client B for a long time, the provider client B can prevent a situation where the requester client a uses traffic without paying for it by cutting off traffic sharing.
After receiving the flow use certificate submitted by the provider client B, the flow sharing contract may calculate, based on the flow use certificate and the unit flow price, a transaction fee corresponding to the current flow sharing, that is, a numerical value of digital money that the requester client a should pay to the provider client B, where the transaction fee is represented by a first numerical value, and the first numerical value represents a numerical value added to an account of the provider client B. The transaction fee may be deducted from the deposit paid by the requester client a in advance, if the second value is 200 and the first value is 150, the deposit is left 50 after the transaction fee is deducted from the deposit of the requester client a, and the remaining deposit may be processed according to the requirement of the requester client a, and if the deposit is returned to the requester client a, that is, the account value of the requester client a is increased by 50, the deposit may not be returned to the requester client a, and the deposit is used when the requester client a needs to pay the transaction fee next time. This completes the transaction process of the resource flow.
It can be seen that, compared with the current situation that network traffic resources are provided for users only by each large telecommunication operator, the traffic is provided for the client of the requester through the provider client selected bidirectionally and autonomously, the monopoly established by each large telecommunication operator by virtue of the advantages of policy, capital, user scale and the like is broken, the blockchain network is introduced to participate in the witness process, the traffic pricing becomes public and transparent, the statistics of traffic use conditions is not counted by one operator, but is jointly witnessed and supervised by multiple parties, the fairness and reasonability of the traffic transaction process are realized, and the requirements of the traffic provider and the traffic requester are both met. The method has the advantages of being not only for the network traffic resource, but also for the transaction of other various resource flows.
Corresponding to the embodiment of the invention shown in fig. 2, the embodiment of the invention also provides a resource flow transaction device applied to the provider client.
Fig. 3 is a schematic structural diagram of a resource flow transaction apparatus applied to a provider client according to an embodiment of the present invention, and as shown in fig. 3, the resource flow transaction apparatus 300 includes: a transaction setup module 301 and a transaction management module 302.
The transaction establishment module 301 is configured to establish an association with a requestor client through a blockchain server, and provide a resource stream to the requestor client, so that the requestor client receives and uses the resource stream.
The transaction management module 302 is configured to obtain credential information representing a state of the requester client using the resource stream, send the credential information to the blockchain server, and determine, by the blockchain server, a first value based on the credential information, where the first value is used to represent a value added to an account of the provider client by the requester client.
By applying the embodiment shown in fig. 3 of the present invention, the transaction of the resource stream is participated in by the blockchain server as a third party from the beginning to the end, and since the blockchain server is an arbitrary node in the blockchain network, and the behavior of any blockchain server is witnessed by other blockchain servers in the blockchain network, a multi-party trusted supervision on the transaction behavior of the resource stream is formed, and no matter a requester, a provider or the blockchain server in the blockchain network cannot cheat, the problem of cheating by any one or more parties of the requester and the provider in the resource stream transaction process can be at least partially solved, alleviated, inhibited, or even avoided, thereby realizing a fair resource stream transaction mode.
In one embodiment of the present disclosure, the transaction establishment module 301 establishes an association with the requestor client through the blockchain server, and providing the resource stream to the requestor client includes: the transaction establishing module 301 is configured to receive transaction request information sent by a blockchain server, where the transaction request information includes identification information of a requester client and a digital signature of the requester client, the transaction request information is sent by the requester client to the blockchain server, and when the transaction request information is granted, send transaction grant information to the blockchain server, where the transaction grant information includes the transaction request information and the digital signature of a provider client, and start providing a resource stream to the requester client.
