Description

Technical Field

[0001] This application seeks protection for an electricity trading technology, and more particularly relates to a blockchain-based electricity trading system. This application also relates to a blockchain-based electricity trading method. Background Technology

[0002] Electricity is the absolute mainstay of energy in modern society's production and daily life, with an extremely wide coverage, basically involving all people. Especially in urban areas, the importance of electricity for both living and production is self-evident.

[0003] Currently, electricity trading can be conducted online, but this trading method is still in a relatively early stage. It uses a centralized database to store and process electricity consumption and transaction data. This method may be vulnerable to cyberattacks on the Internet. At the same time, the data center operator, as an intermediary between the seller and the buyer in electricity trading, cannot guarantee a trustworthy transaction. Therefore, a new electricity trading system is needed. Summary of the Invention

[0004] To address the problems in the prior art, this application provides a blockchain-based power trading system. This application also relates to a blockchain-based power trading method.

[0005] This application provides a blockchain-based electricity trading system, including: a seller, a buyer, and a third-party platform;

[0006] The third-party platform obtains electricity information, generates seller transaction documents based on the electricity information, and sends the seller transaction documents and seller information to the blockchain for identity verification.

[0007] The third-party platform obtains user information, generates buyer transaction documents based on the user information, and sends the seller transaction documents and user information to the blockchain for identity verification.

[0008] The buyer generates a random number and sends the random number to both the seller and the third-party platform. The seller then generates a verification code based on the random number and sends it to the third-party platform.

[0009] The third-party platform decodes the verification code, obtains the decoded random number contained in the verification code, compares it with the random number sent by the buyer, and verifies it. If the verification is successful, the seller's transaction document and the buyer's transaction document are merged to generate an electricity transaction document, which is sent to the seller and the buyer respectively, and the transaction is executed.

[0010] Optionally, after the electricity transaction document is sent to the seller, a payment link will be generated based on the consumption amount in the electricity transaction document and sent to the buyer.

[0011] Optionally, the third-party platform may be connected to the seller and the buyer via different links.

[0012] Optionally, the verification code is generated based on multiple algorithms, wherein the verification code includes a time code, and the algorithm category at that time is determined based on the time code.

[0013] Optionally, the timecode is provided by the third-party platform.

[0014] This application also provides a blockchain-based electricity trading method, including:

[0015] Obtain electricity information, generate seller transaction documents based on the electricity information, and send the seller transaction documents and seller information to the blockchain for identity verification;

[0016] Obtain user information, generate buyer transaction documents based on the user information, and send the seller transaction documents and user information to the blockchain for identity verification;

[0017] The system receives a random number generated by the buyer and a verification code generated by the seller based on the random number. It decodes the verification code to obtain the decoded random number contained in the verification code and compares it with the random number. If the verification is successful, the system merges the seller's transaction document and the buyer's transaction document to generate an electricity transaction document.

[0018] Optionally, after the electricity transaction document is sent to the seller, a payment link will be generated based on the consumption amount in the electricity transaction document and sent to the buyer.

[0019] Optionally, the third-party platform may be connected to the seller and the buyer via different links.

[0020] Optionally, the verification code is generated based on multiple algorithms, wherein the verification code includes a time code, and the algorithm category at that time is determined based on the time code.

[0021] Optionally, the timecode is provided by the third-party platform.

[0027] The following are examples of specific implementation processes provided to illustrate the technical solutions to be protected in this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can implement this application by different technical means under the guidance of the concept of this application. Therefore, this application is not limited to the specific embodiments below.

[0028] This application provides a blockchain-based power trading system, comprising: a seller, a buyer, and a third-party platform; the third-party platform acquires power information, generates a seller transaction document based on the power information, and sends the seller transaction document and seller information to the blockchain for identity verification; the third-party platform acquires user information, generates a buyer transaction document based on the user information, and sends the seller transaction document and user information to the blockchain for identity verification; the buyer generates a random number and sends the random number to both the seller and the third-party platform; the seller generates a verification code based on the random number and sends it to the third-party platform; the third-party platform decodes the verification code, obtains the decoded random number contained in the verification code, compares it with the random number sent by the buyer, and if the verification is successful, merges the seller transaction document and the buyer transaction document to generate a power trading document, sends it to both the seller and the buyer, and executes the transaction.

[0029] Figure 1 This is a schematic diagram of the blockchain-based power trading system described in this application.

[0030] Please refer to Figure 1 As shown, the seller 101 is an electricity provider, the buyer 102 is an electricity consumer, and the third-party platform 103 is an electricity trading platform.

[0031] Figure 2 This is a diagram of the transaction system link structure in this application.

[0032] Please refer to Figure 2 As shown, each third-party platform connects to multiple sellers 101 and buyers 102.

[0033] The third-party platform 103 acquires electricity information, generates seller transaction documents based on the electricity information, and sends the seller transaction documents and seller information to the blockchain for identity verification.

[0034] The seller 101 data includes: name, authentication information, etc., and the electricity information includes: electricity parameters, electricity price, and other related electricity information.

[0035] The seller information and power information are obtained, and a seller transaction document is generated based on the seller signal and power information. The transaction document includes at least the power price, the power supply time interval, the power price change rules during the power supply time interval, and other power consumption rules and power purchase rules.

[0036] The seller information and the electricity information are related, and this relationship can be achieved through the same tag. Based on the relationship, the seller transaction documents and seller information are sent to the blockchain for authentication.

[0037] The identity verification refers to storing and recording the seller's transaction document and the corresponding seller information on the blockchain, and verifying whether the information is genuine.

[0038] In this application, the verification is actually performed through the distributed recording rules of the blockchain to verify anti-counterfeiting, and the seller's promised transaction documents are recorded through the distributed rules.

[0039] The third-party platform 103 obtains user information, generates buyer transaction documents based on the user information, and sends the seller transaction documents and user information to the blockchain for identity verification.

[0040] In this application, "buyer 102" refers to the same person as "user," and both terms have the same meaning. "Buyer 102" refers to an electricity consumer.

[0041] When purchasing electricity, buyer 102 first sends a purchase request to the third-party platform 103. The purchase request includes the buyer's user information, which at least includes the amount of electricity to be purchased and the type of purchase.

[0042] Based on the user information, a buyer's transaction document is generated, and the buyer's transaction document and user information are sent to the blockchain for identity verification.

[0043] Specifically, the identity verification of the buyer 102 is the same as that of the seller 101, which involves storing and recording the buyer's transaction documents and user information, and verifying whether the information is true.

[0044] The blockchain described in this application is created based on the third-party platform 103. There are multiple third-party platforms 103, and each third-party platform 103 corresponds to a different seller 101 and buyer 102. However, when performing the identity verification, any one of the third-party platforms 103 sends the electricity information, seller transaction documents, user information and buyer transaction documents, which are then verified, stored and recorded by the other third-party transaction platforms 103.

[0045] The buyer 102 generates a random number and sends the random number to the seller 101 and the third-party platform 103 respectively. The seller 101 generates a verification code based on the random number and sends it to the third-party platform.

[0046] In the specific transaction process, the buyer 102 is the active party, and the seller 101 is the passive party. The active party means that all transaction instructions are sent by the buyer 102, because the buyer 102 is the payer. The seller 101 is the passive party, but the seller 101 can set rules that the electricity transaction can only be carried out after payment is received.

[0047] Based on the above rules, the buyer 102 first generates a random number to verify the authenticity of all parties. Since the information of the buyer 102 and the seller 101 has been verified and stored on the blockchain, only simple verification is needed to determine the authenticity.

[0048] First, buyer 102 generates a random number, which is then sent to seller 101 and third-party platform 103. Seller 101 generates a verification code based on the random number and sends it to third-party platform 103.

[0049] The verification code is generated based on the random data using different algorithms, such as different versions of the national cryptographic algorithm or hash algorithm.

[0050] The third-party platform 103 decodes the verification code, obtains the decoded random number contained in the verification code, compares it with the random number sent by the buyer 102, and verifies it. If the verification is successful, the transaction documents of the seller 101 and the buyer 102 are merged to generate an electricity transaction document, which is then sent to the seller 101 and the buyer 102 respectively, and the transaction is executed.

[0051] Specifically, the verification code verification means that the verification random number and the random number are the same. After the verification is completed, the third-party platform 103 merges the seller's transaction document and the buyer's transaction document to generate an electricity transaction document, and sends the electricity transaction document to the buyer 102 and the seller 101 respectively, and the seller 101 and the buyer 102 execute the electricity transaction.

[0052] The transaction steps include: the seller generating a payment connection based on the consumption amount recorded in the electricity transaction document and sending it to the buyer 102.

[0053] The buyer 101 completes the payment, and the seller verifies whether the payment is completed and sends the power through the payment port.

[0054] Preferably, the third-party platform is connected to the seller and the buyer through different links, specifically one-to-one individual connections.

[0055] Preferably, the verification code is generated based on multiple algorithms, and the verification code includes a time code. The algorithm category at that time is determined based on the time code. This includes reading time information from the third-party platform, generating a time code based on the time information, and sending the time code to the seller 101. The seller 101 adds the time code to the verification code when generating the verification code.

[0056] This application also provides a blockchain-based electricity trading method, which uses blockchain for identity authentication and information storage, avoiding issues of transaction integrity and data centralization.

[0057] Figure 3 This is a flowchart of the blockchain-based electricity trading process in this application.

[0058] Please refer to Figure 3 As shown, S101 acquires electricity information, generates a seller transaction document based on the electricity information, and sends the seller transaction document and seller information to the blockchain for identity verification.

[0059] The third-party platform 103 acquires electricity information, generates seller transaction documents based on the electricity information, and sends the seller transaction documents and seller information to the blockchain for identity verification.

[0060] The seller 101 data includes: name, authentication information, etc., and the electricity information includes: electricity parameters, electricity price, and other related electricity information.

[0061] The seller information and power information are obtained, and a seller transaction document is generated based on the seller signal and power information. The transaction document includes at least the power price, the power supply time interval, the power price change rules during the power supply time interval, and other power consumption rules and power purchase rules.

[0062] The seller information and the electricity information are related, and this relationship can be achieved through the same tag. Based on the relationship, the seller transaction documents and seller information are sent to the blockchain for authentication.

[0063] The identity verification refers to storing and recording the seller's transaction document and the corresponding seller information on the blockchain, and verifying whether the information is genuine.

[0064] In this application, the verification is actually performed through the distributed recording rules of the blockchain to verify anti-counterfeiting, and the seller's promised transaction documents are recorded through the distributed rules.

[0065] Please refer to Figure 3 As shown, S102 obtains user information, generates a buyer's transaction document based on the user information, and sends the seller's transaction document and user information to the blockchain for identity verification.

[0066] In this application, "buyer 102" refers to the same person as "user," and both terms have the same meaning. "Buyer 102" refers to an electricity consumer.

[0067] When purchasing electricity, buyer 102 first sends a purchase request to the third-party platform 103. The purchase request includes the buyer's user information, which at least includes the amount of electricity to be purchased and the type of purchase.

[0068] Based on the user information, a buyer's transaction document is generated, and the buyer's transaction document and user information are sent to the blockchain for identity verification.

[0069] Specifically, the identity verification of the buyer 102 is the same as that of the seller 101, which involves storing and recording the buyer's transaction documents and user information, and verifying whether the information is true.

[0070] The blockchain described in this application is created based on the third-party platform 103. There are multiple third-party platforms 103, and each third-party platform 103 corresponds to a different seller 101 and buyer 102. However, when performing the identity verification, any one of the third-party platforms 103 sends the electricity information, seller transaction documents, user information and buyer transaction documents, which are then verified, stored and recorded by the other third-party transaction platforms 103.

[0071] The buyer 102 generates a random number and sends the random number to the seller 101 and the third-party platform 103 respectively. The seller 101 generates a verification code based on the random number and sends it to the third-party platform.

[0072] In the specific transaction process, the buyer 102 is the active party, and the seller 101 is the passive party. The active party means that all transaction instructions are sent by the buyer 102, because the buyer 102 is the payer. The seller 101 is the passive party, but the seller 101 can set rules that the electricity transaction can only be carried out after payment is received.

[0073] Based on the above rules, the buyer 102 first generates a random number to verify the authenticity of all parties. Since the information of the buyer 102 and the seller 101 has been verified and stored on the blockchain, only simple verification is needed to determine the authenticity.

[0074] First, buyer 102 generates a random number, which is then sent to seller 101 and third-party platform 103. Seller 101 generates a verification code based on the random number and sends it to third-party platform 103.

[0075] The verification code is generated based on the random data using different algorithms, such as different versions of the national cryptographic algorithm or hash algorithm.

[0076] Please refer to Figure 3As shown, S103 receives the random number generated by the buyer and the verification code generated by the seller based on the random number, decodes the verification code to obtain the decoded random number contained in the verification code, compares it with the random number, and if the verification is successful, merges the seller's transaction document and the buyer's transaction document to generate an electricity transaction document.

[0077] Specifically, the verification code verification means that the verification random number and the random number are the same. After the verification is completed, the third-party platform 103 merges the seller's transaction document and the buyer's transaction document to generate an electricity transaction document, and sends the electricity transaction document to the buyer 102 and the seller 101 respectively, and the seller 101 and the buyer 102 execute the electricity transaction.

[0078] The transaction steps include: the seller generating a payment connection based on the consumption amount recorded in the electricity transaction document and sending it to the buyer 102.

[0079] The buyer 101 completes the payment, and the seller verifies whether the payment is completed and sends the power through the payment port.

[0080] Preferably, the third-party platform is connected to the seller and the buyer through different links, specifically one-to-one individual connections.

[0081] Preferably, the verification code is generated based on multiple algorithms, and the verification code includes a time code. The algorithm category at that time is determined based on the time code. This includes reading time information from the third-party platform, generating a time code based on the time information, and sending the time code to the seller 101. The seller 101 adds the time code to the verification code when generating the verification code.
