The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The embodiments of the present disclosure are described below with specific examples, and other advantages and effects of the present disclosure will be readily apparent to those skilled in the art from the disclosure in the specification. It is to be understood that the described embodiments are merely illustrative of some, and not restrictive, of the embodiments of the disclosure. The disclosure may be embodied or carried out in various other specific embodiments, and various modifications and changes may be made in the details within the description without departing from the spirit of the disclosure. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The block chain is formed by combining and arranging blocks in a chain form. The persistent storage of electronic records is called a block, and each block records useful information about the relevant transaction activities that occur as it is formed, and is created, sorted, and aggregated into a set in chronological order. The block chains are connected according to a time sequence, and if the next block cannot master the transaction information of the previous block, the next block cannot be generated. In other words, the generation of a new block depends on the entire transaction of the previous block, which may form a long data link from the first block to the current block if the block header contains the information compression value of the previous block. Thus, the data are packed into a huge database. Meanwhile, the unique cryptology mode and formula algorithm are used for ensuring the non-imitability of the anti-counterfeiting product. When each new transaction is made, all other nodes are updated, and all nodes have read-only rights to the public ledger.

The invention discloses a block chain-based electric power transaction method, which comprises the following steps:

step 1, the transaction center issues transaction notices, and the transaction notices form a transaction sequence and are linked.

The transaction notice comprises the time of the transaction, the transaction scale, the setting of the participant, the number of declaration sections and the like.

The uplink writes data to the block chain. The winding up includes manual winding up and automatic winding up, and the winding up in this application is only automatic winding up. And (4) linking the transaction notice, wherein the triggering condition is when the transaction notice is approved and issued.

And 2, the transaction center sets respective reporting constraints of the electricity purchasing party and the electricity selling party of the transaction sequence, and links the reporting constraints.

The reporting constraint comprises reporting electric quantity, reporting electrovalence and the like. The trigger condition for restricting the information uplink is when the information is saved.

And 3, reporting the electric quantity and the electricity price by the electricity purchasing party and the electricity selling party according to the convention in the transaction notice at the specified reporting time, and linking the reporting data.

A market main body can report a plurality of data segments at one time, and can report a plurality of times, and the last data is automatically invalidated after reporting. The market body declares the time and encrypts the declaration price of electricity through the public key.

The power utilization enterprise reports and reports the electric quantity and the electricity price from the page of the transaction system, and calls a chain-up program after sending the electric quantity and the electricity price to a back-end warehouse; before the chain is linked, the identity information of the market main body, the data chain and the service number 'JZJJ _ transaction serial number' of the service are carried before the data chain.

And 4, setting a priority rule by the transaction center, and carrying out priority sequencing and chain loading on the electricity sellers according to the priority rule.

The priority rules are that when the electricity prices declared by the electricity selling parties are consistent, the electricity selling parties of the low-coal-consumption unit take precedence, the declaration time takes precedence, and the like.

The triggering condition of the data uplink with the priority sequence is that the trading center stores the power plant sequence.

And 5, the transaction center decrypts the declared price of electricity by using the specified private key.

Writing a decrypted intelligent contract, chaining the intelligent contract through the block chain platform, wherein the calling authority of the intelligent contract is only available to the trading center. The functions are as follows:

acquiring a private key and declaration data through a service single number;

decrypting the declaration data through a private key;

chaining the declaration data and checking by an intelligent transaction center;

and 6, the transaction center performs matching calculation to generate an intelligent contract and links the chain.

Further, in a preferred embodiment of the present application, step 6 comprises:

601, acquiring the transaction scale in the transaction notice information through the service order number;

step 602, acquiring matching parameter information and priority ranking of power sellers through the service order number;

Step 603, acquiring decrypted declaration data through the service single number;

and step 604, performing matching calculation according to the matching rule, generating an intelligent contract and linking the chain, and linking the chain of the matching parameters.

The intelligent contract includes information: event, contract address, construction function, execution function and other information of the intelligent contract.

Further, the matching rule is as follows: the trading center sorts the declared prices of the electricity purchasing side from low to high and the declared prices of the electricity selling side from high to low through a calculation mode of high-low matching under the condition that a set trading scale is met, and an intelligent contract is generated until the declared price of the electricity purchasing side minus the declared price of the electricity selling side is more than or equal to zero.

The triggering condition of the matching parameter uplink is when the matching parameter is stored.

The chain is divided into two steps, wherein in the first step, only the trading center can check all data blocks; and in the second step, the cochain is respectively packaged according to the successful bid condition of the power utilization enterprise, and the cochain block can only be seen by the identity of the market main body.

The intelligent contract decryption algorithm comprises the steps of firstly uploading an intelligent contract by using a transaction center account login block chain platform, then chaining a decryption password when a main system decrypts each time, finally triggering the decryption intelligent contract to click decryption in a demonstration system for the transaction center, automatically acquiring a decryption key and effective declaration data by the intelligent contract, decrypting the decryption key and the effective declaration data, and simultaneously storing decryption information as private information of the transaction center account.

When an intelligent contract of a privacy protection scheme is constructed, the privacy protection problem of trusted data is solved by utilizing a block chain: the important data of the electric power transaction are encrypted and then linked, any user or an electric enterprise on the link cannot access the related data under the condition that the user or the electric enterprise is not authorized, the privacy of the authorized user is guaranteed to the maximum extent, and the authorization process can be authorized simultaneously or independently during information release according to different application scenes.
