Similarly, computer device 102 may be a requester requiring use of the resource stream, computer device 101 may be a provider capable of providing the resource stream, after the transaction of the resource stream is started, computer device 101 provides the corresponding resource stream to computer device 102, computer device 102 receives and uses the resource stream, after computer device 102 stops using the resource stream, computer device 102 pays a corresponding transaction fee to computer device 101 according to the total amount of the resource stream used by computer device 102, and the transaction is ended after the transaction fee is paid.
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, depending on the implementation desired.
Fig. 2 is a schematic flow chart of a resource flow transaction method applied to a client of a requester according to an embodiment of the present invention; as shown in fig. 2, the method is applied to a requester client, and a transaction process of a resource stream provided by the present disclosure is explained below from the perspective of the requester client.
As shown in fig. 2, the method includes:
s201: selecting a provider client, and establishing association with the provider client through a blockchain server.
S202: a resource stream provided by the provider client is received and used.
S203: generating credential information representing the state of using the resource flow according to a preset rule, sending the credential information to a blockchain server, and determining a first numerical value by the blockchain server based on the credential information, wherein the first numerical value is used for representing a numerical value added to an account of the provider client by a requester client.
It can be seen that the method shown in fig. 2 establishes an association with a selected provider client to conduct a transaction before the transaction begins, enables the blockchain server to supervise the status of the transaction by sending credential information to the blockchain server while the transaction is in progress, and determines the transaction fee for payment by the blockchain server after the transaction is over. 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 witnessed 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 servers in the blockchain network can not cheat no matter a requesting party, a providing party or the block chain network, and a fair resource flow transaction mode 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, step S201 of the method shown in fig. 2 selects a provider client, and establishing an association with the provider client through a blockchain server includes: the method comprises the steps of obtaining resource flow publishing information of a plurality of provider clients, wherein the resource flow publishing information comprises identification information of the provider clients and price information of resource flows, selecting one provider client based on the plurality of resource flow publishing information, sending transaction request information to a blockchain server, and forwarding the transaction request information to the selected provider client by the blockchain server, so that the provider clients start providing the resource flows when the transaction request information is permitted.
According to the embodiment, any provider client can send resource flow release information according to the characteristics of the resource flow of the provider client, the resource flow release information can be acquired by any requester client, the resource flow release information can include the related information such as the type, the quantity, the price and the like of the resource flow which can be provided, any requester client can select a proper provider client according to the requirement of the requester client, the transaction request information is sent to the provider client through the block chain server after the selected provider client is determined, and the transaction of the resource flow can be started after the permission of the provider client is obtained.
As an optional embodiment, the transaction request information sent by the requester client after selecting the provider client may include a digital signature of the requester client, so that the blockchain server forwards the transaction request information to the provider client when verifying that the transaction request information is true based on the digital signature of the requester client. It can be seen that, in this embodiment, the authenticity of the transaction request information can be verified through the digital signature of the requesting client carried in the transaction request information, and only when the transaction request information is authentic, the transaction request information is forwarded to the providing client through the blockchain server, and the corresponding transaction can be performed.
Specifically, the digital signature of the requester client may be formed through asymmetric encryption, for example, the requester client encrypts the transaction request information based on its own private key to obtain the digital signature of the requester client, and the blockchain server may verify the authenticity of the transaction request information by using the public key corresponding to the requester client, for example, in this embodiment, the digital signatures of both parties of the transaction may be formed through asymmetric encryption, and for any requester client, the requester 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, the public key of the requester client may be obtained by other requester clients, each provider client, and/or each blockchain server, and the private key is not public, 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 also have a dedicated key pair, and any blockchain server may also 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 ways, and the goal is to prove the authenticity of the sent information to a plurality of blockchain servers as third parties, and any way that can achieve this goal is possible, which is not limited herein.
Specifically, in this embodiment, the above-mentioned asymmetric encryption manner may also be adopted to form digital signatures of two parties of a transaction, for example, the requesting client may encrypt the resource stream usage certificate based on its private key to obtain the digital signature of the requesting client, the providing client may encrypt the resource stream usage certificate and the digital signature of the requesting client based on its 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.
In one embodiment of the present disclosure, the step S203 of the method shown in fig. 2 generates credential information representing a state of using the resource stream according to a preset rule, and the sending the credential information to the blockchain server includes: during the use of the resource flow, generating a resource flow use certificate representing the current use state at preset time intervals, sending the resource flow use certificate to the provider client, and sending the resource flow use certificate to the blockchain server by the provider client. Namely, the credential information is generated by the client of the requester, sent to the client of the provider from the client of the requester, and then sent to the blockchain server in the blockchain network from the client of the provider, so that a common witness of multiple parties to the credential information is formed. In this embodiment, the resource flow usage credentials are generated over time, and the provider client may send each resource flow usage credential received by the provider client to the blockchain server, or may send one or more of the received resource flow usage credentials to the blockchain server, for example, the last resource flow usage credential generated by the requester client may be sent to the blockchain server.
For example, after starting to use the resource stream, the requester client may generate a resource stream usage credential at intervals of a preset time interval T and send the resource stream usage credential to the provider client providing the resource stream, where the resource stream usage credential may record information such as the number of resource streams currently used by the requester client, so that the corresponding provider client knows the current state and situation of the requester client using the resource stream, and may timely stop the supply of the resource stream when the requester client no longer continues to use the resource stream, and may subsequently calculate a corresponding transaction fee according to the total amount of the resource stream used by the requester client.
Further, in order to increase the reliability of the credential information and avoid the credential information from being forged or tampered in the transmission process, as an optional embodiment, the resource stream usage credential further includes a digital signature of the requesting client in addition to the information characterizing the usage state of the resource stream, so that the provider client sends the resource stream usage credential to the blockchain server when verifying that the resource stream usage credential is true based on the digital signature of the requesting client. In the embodiment, the authenticity of the resource flow use credential is proved by adding the digital signature of the requesting client to the resource flow use credential, and the resource flow use credential is considered to be valid only if the providing client sends the resource flow use credential to the blockchain server if the resource flow use credential is authentic.
Specifically, the digital signature of the requester client may be formed through asymmetric encryption, for example, the requester client encrypts the resource flow usage credential based on a private key of the requester client to obtain the digital signature of the requester client, and the provider client may verify the authenticity of the resource flow usage credential by using a public key corresponding to the requester client, which is described above and is not described herein again.
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.
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 the multi-party credible supervision on 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 a certain time and a certain place, 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 method further includes generating a digital signature a1 for the requestor client a based on the generated transaction request information and a private key of the requestor client a, the digital signature a1 being appended to the generated transaction request information, the identifying information of the requestor client a, the identifying information of the selected provider client B, the expected usage traffic volume, and a second value characterizing the amount of the prepaid deposit, the second value corresponding to a value of the digital currency decremented from the account of the requestor client a. The requestor client a sends the transaction request message to a traffic sharing contract running in the blockchain server, the traffic sharing contract verifies that the transaction request message is authentic according to the public key of the requestor client a and the digital signature a1, 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 appended to the received transaction request information to form transaction approval information, which the provider client B sends to the traffic sharing contract indicating agreement to traffic sharing and to start 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 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 traffic use credential received last 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 can calculate the transaction cost corresponding to the current flow sharing based on the flow use certificate and the unit flow price, that is, the value of the digital currency that the requester client a should pay to the provider client B, the transaction cost is represented by a first value, and the first value represents the value added to the 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. The transaction process of the resource flow is completed.
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 satisfied. The method has the advantages of being not only for the network traffic resource, but also for the transaction of other various resource flows.
In the embodiment of the invention shown in fig. 2, the embodiment of the invention further provides a resource flow transaction apparatus applied to the client of the requester.
