Fig. 1 is a flowchart of a distributed power generation listing transaction method according to an embodiment of the present invention.
As shown in fig. 1, it shows a flowchart of an implementation of a distributed generation listing transaction method provided by an embodiment of the present invention, which is detailed as follows:
in step 101, an offer of a first user is obtained, wherein the offer characterizes a condition for fulfilling a transaction.
In some embodiments, the first user and the second user are each registered as legitimate transaction users, and the registering step includes:
acquiring a fund account of a registered applicant, wherein the fund account has a fund transfer function and has funds with preset conditions;
generating a block with encryption information and a hash value according to the registration information of the registered applicant and the fund account, and adding the block into a block chain;
the registration information is published to all legal transaction users for a preset time limit;
and if no objection is received at the end of the predetermined term, generating a registration account number, a password and a secret key according to the registration information of the registered applicant.
In some embodiments, the obtaining funds from the registered funds account by the first user or the second user is a power-selling user includes:
acquiring a network access notice, and generating a network access statement according to the network access notice, wherein the network access notice comprises a network access display period and a pricing mode, and the network access statement comprises a risk electricity selling offer which needs to be lifted after the display period is finished;
generating a block with encryption information and a hash value by the network access declaration, and adding the block into a block chain;
according to the network access showing period, showing the network access statement and the risk electricity selling offer to all legal transaction users, and after showing is finished, lifting the risk electricity selling offer;
after the formula deadline is over, responding to the risk electricity selling offer, and performing risk electricity selling operation;
and after the risk electricity selling operation is finished, transferring the fund account of the electricity purchasing user to the fund account of the electricity selling user according to a pricing mode appointed in the network access need, transferring the risk electricity selling need and the fund account of the electricity purchasing user to the fund account of the electricity selling user according to the pricing mode appointed in the network access need to generate a block with encrypted information and a hash value, and adding the block into a block chain.
Illustratively, as shown in fig. 2, a distributed power generation listing transaction system is provided with a server 201 and a plurality of distributed terminals 202, wherein the distributed terminals 202 are used for storing block chains, and the server 201 is used for scheduling, encrypting and decrypting intermediate information generated in the transaction process.
The first user and the second user may be electricity selling users or electricity purchasing users, and the first user and the second user have corresponding settings, for example, when the first user is an electricity selling user, the second user is an electricity purchasing user, and when the first user is an electricity purchasing user, the second user is an electricity selling user. In some application scenarios, distributed terminal 202 is a terminal for a transaction for a first user and a second user.
The user who becomes the electricity selling user or the electricity purchasing user must have a fund account, and the account has certain transferable funds. And the electricity selling user or the electricity purchasing user submits registration information and fund accounts meeting the conditions to the server, and the registration information and the fund accounts are encrypted and then stored in the blockchain.
Then, the registration information is disclosed to the registered users for a certain period, for example, the period of the disclosure is 15 working days. If no feedback of the registered user is received at the end of the public service period, a registered account number, a password and a secret key are generated according to the registered information and the information is sent to the registered applicant.
One of the roles of the bulletin is to make it almost impossible to modify the blocks of the registered information and the fund account again by adding new information in the block chain so that the blocks are linked by other blocks, and the other is to inform and accept the supervision of the already registered user.
The key is used for guaranteeing the data transmission safety between the server and the distributed terminal, and the data can be decrypted only by the terminal party holding the key.
For the electricity selling user, before applying for registration, the fund of the fund account can obtain a fund by selling the electric energy generated by electricity generation to the registered user. I.e., a beneficial way, to obtain funds.
Before selling, drawing a network-accessing statement according to the network-accessing notice, wherein the network-accessing statement describes the price of selling electricity, the network-accessing statement also needs a period of formula in the registered user, and the transaction can be carried out after the period is over. The network entry announcements are also added to the blockchain in the form of blocks.
After the public notice is finished, if a registered user is willing to undertake the transaction, the fund of the registered user is transferred to an account of the electricity purchasing user according to the offer in the network access statement after the transaction is finished, and the account information of the electricity purchasing user is encrypted and added into the block chain.
In step 102, when the offer meets a verification condition, the offer is added to a transaction listing sequence, wherein the transaction listing sequence comprises a plurality of offers.
In some embodiments, step 102 comprises:
decrypting the offer according to the key of the first user to obtain a plaintext of the offer, wherein the plaintext comprises: registering an account number, a password, a transaction unit price, a transaction total amount and a transaction time period;
after the correctness of the registered account number is verified through the password, the available funds of the fund account are obtained according to the registered account number;
determining a maximum transaction amount according to the available funds and the default fund proportion;
determining an expected transaction amount according to the transaction unit price and the transaction total amount;
if the maximum transaction amount is larger than the predicted transaction amount, generating a frozen fund amount according to the default fund proportion and the predicted transaction amount;
freezing funds of the frozen fund amount in the available funds of the first user, generating a first frozen certificate and a first unfreezing application code, and adding the first frozen certificate and the blocks of the corresponding hash values into a block chain;
encrypting the first frozen certificate and the first unfreezing application code by using a secret key of the first user, and sending the encrypted first frozen certificate and the encrypted first unfreezing application code to the first user;
and adding the registered account number of the first user, the transaction unit price, the transaction total amount and the transaction time interval into the foremost end of a transaction queue, and disclosing all legal transaction users.
Illustratively, before a transaction is made, the user needs to add an offer to the transaction listing sequence in anticipation of other users being able to offer.
The user encrypts the offer by the secret key and transmits the encrypted offer to the server, the server decrypts the offer content according to the secret key of the user to obtain a plaintext of the offer, transaction unit price, transaction total amount and transaction time period are recorded in the plaintext, after the identity of the user is verified to be correct, available funds of a user account are inquired firstly, and then the maximum transaction amount supported by the available funds is determined according to the available funds and the default golden ratio.
Then, the expected transaction amount is determined according to the transaction unit price and the transaction total amount. If the predicted transaction amount does not exceed the maximum transaction amount, the available funds are frozen according to the predicted transaction amount.
After freezing, a freezing voucher and a freezing application code are generated and are sent to a user after being encrypted through a secret key, and the freezing voucher can be stored in a block chain. After the above operations are completed, the offer may be added to the transaction queue for posting to the registered user.
In step 103, in response to the offer of the second user, when the second user meets the verification condition, a transaction contract is generated and the offer is deleted from the transaction listing sequence.
In some embodiments, step 103 comprises:
confirming that the amount of funds available in the second user account is not less than the projected transaction amount;
encrypting the frozen fund amount and the dynamic code according to the secret key of the second user to generate a frozen notification ciphertext;
if a notification response from the second user and a code corresponding to the dynamic code are received within a preset period, freezing funds of the frozen amount in the funds available for the second user, generating a second freezing certificate and a second unfreezing application code, and adding the second freezing certificate and a corresponding hash value into a blockchain;
encrypting the second frozen certificate and the second unfreezing application code by using a secret key of the second user, and sending the encrypted second frozen certificate and the second unfreezing application code to the second user;
