The both parties of electric energy are unable to get the private key；But the corresponding public key of the private key is public information, the both parties of electric energy
Can it know.Method of commerce includes：
Step 301)：Key pair is generated, account is obtained；Wherein, the key pair includes private key and public key.
In the present embodiment, account refer to it is a pair of can be with the key pair (public key and private key) of one user of unique mark.Wherein,
Private key is held by the owner of account, not external disclosure, and user can sign to one piece of data using the private key, to show
Oneself approval to the data.Public key external disclosure can verify whether some signature is that the public key corresponds to using the public key
Private key sign and issue.During the signature of this asymmetric encryption and verification, and privacy of user is protected, guaranteed data
Safety.
In block chain network, there is the account of following several types：
1. issuing account, corresponding is the side of selling (power supply bureau) of electric energy.
2. accounts of consumption, corresponding is the consumer of electric energy.
3. measuring account, corresponding is the measuring terminal (ammeter) of electric energy.
Step 302)：Transaction data is obtained in the account, and according to the transaction data, the private key and the public affairs
Key builds Transaction Information.
In the present embodiment, account is by sending the sides of the data of one section of key signature by oneself to block chain network
Formula, to allow block chain network to record or change the data on block chain.Record or the data of modification are Transaction Information.Transaction Information
Data format and type provide that only format is correct by block chain network, signature is correct, and the data manipulation in merchandising is symbol
Close set operation condition (such as:Whether have corresponding permission, if having sufficient remaining sum etc.) transaction be possible to by
Network receives and is written into final block chain data.
In the technical scheme, the Transaction Information stored in the form of block chain, i.e., the transaction letter recorded in each block
Breath is reached common understanding by distributed network, and ensures the continuity and not of data by recording the form of previous block Hash
It can distort, to ensure that the reliability of data.Do not include the privacy information of user in Transaction Information, only includes public key and label
Name, for public key with society Identity Association and there is no in block chain, Transaction Information is stored in distribution in the form of block chain
In network, it can not be modified by the data of block chained record.Any node in network can receive transaction or inquiry is handed over
Easy information.
In the present embodiment, a basic transaction includes following several fields：
| Field | Explanation |
| Sign and issue account | Sign and issue the public key of the account of the transaction |
| Type of transaction | The type of transaction |
| Transaction data | The data of the corresponding type of transaction |
| Time | Transaction acknowledging time at the latest is then merchandised calcellation more than the time |
| Signature | By result of the private key to above-mentioned data signature for signing and issuing account |
In the detailed description of the manageable type of transaction of block chain network：
The distribution of token is merchandised, and is signed and issued by issuing account, and issuing account can authorize specified consumed accounts by this kind of transaction
The specified token amount in family.
The money transfer transactions of token, the accounts of consumption by holding token are signed and issued, and are held the accounts of consumption of token and can be passed through this
Token is transferred to another accounts of consumption by one transaction.
Metering authorizes transaction, is signed and issued by accounts of consumption, accounts of consumption can authorize a certain metering account by this transaction
Reduce the right of the scrip balances in account.
Metering, which authorizes, releases transaction, is signed and issued by accounts of consumption, and accounts of consumption can be cancelled by this transaction to a certain meter
Measure the mandate of account.
Metering transaction, is signed and issued by metering account, which will include the metrical information that metering account measures, and from mandate
Trading account in the token amount that deducts.
In the present embodiment, token is the basic measurement unit of expense in block chain network, is issued by issuing account, consumption
Account is held, metering account consumption.In principle, the franc of token and society bind, only by issuing account provide franc with
The conversion services of token.Token can circulate between accounts of consumption.Token can be mutually forwarded between different accounts of consumption, than
Such as：Agency's (bank or other generations fill mechanism), which can also be used as an accounts of consumption, to be existed, and power supply bureau is issued to these
After account, these accounts can be distributed further to scattered accounts of consumption (common power customer).And scattered accounts of consumption
Between can also by shift token form achieve the purpose that supplement with money.
Step 303)：Whether legal verify the Transaction Information, in the case of legal, the Transaction Information broadcast to
Entire block chain network the Transaction Information is written in block chain until the entire block chain network is reached common understanding.
In the present embodiment, trusted node is reached by way of PoW (proof of work) come what is known together, specific to calculate
The PoW algorithms of method reference bits coin.Because network itself is semi-enclosed, will not cause bit coin like that because dig mine contest and
The consumption of caused mass energy and slower confirmation speed.Again because network is semi-open, the node in addition to generating block
Outside, other nodes (trusted node and non-trusted node) can verify the data in network, and this guarantees blocks
Generation node can not practise fraud and altered data.
Step 304)：Corresponding trading activity is executed in the account according to the Transaction Information in the block chain.
In the present embodiment, the node in network initiates inquiry transaction with arbitrary node of the public key of account into network.
This is an inquiry operation to block chain network, because each service node preserves complete data, it is possible to think
Any one node that can be connected initiates inquiry request.
In the present embodiment, non-encrypted algorithm is generated in the program that consumer side is set by " user " shown in Fig. 2, is disappeared
The private key that expense person side holds oneself, and corresponding public key is supplied to the service node that power supply bureau side is run, this pair of secret keys is
Represent accounts of consumption hereinbefore.The preservation form of corresponding private key is including but not limited to electronic document, IC card data etc..Private key
It is generated by the Encryption Algorithm of block chain, can just be received by block chain network by the transaction of the private key signature at random.
In practice, consumer pays franc to power supply bureau.In technology implementation, the service node of power supply bureau side's operation is used
Issuing account initiates to merchandise for the distribution of the accounts of consumption, authorizes the corresponding token volume of service node of consumer side operation
Degree.It is that concrete implementation form includes but be not limited to sales counter operation, network trading etc..
Distribution transaction is a transaction of the private key signature generated in the program set by " user " shown in Fig. 2, is handed over
Any node for being easily sent to block chain network is broadcast to entire block chain network if the transaction is verified legal, until
Network is reached common understanding, and is written into block data, at this point, will produce token amount on accounts of consumption.
In practice, the accounts of consumption for the Program Generating that consumer side is set by " user " shown in Fig. 2 initiates metering
Transaction is authorized, the public key of corresponding measuring terminals is specified in transaction.Same accounts of consumption can authorize multiple measurements simultaneously herein
Terminal, all measuring terminals share the scrip balances of the accounts of consumption, first with first obtaining, are finished and stop.It is accounts of consumption to fill table
One metering of private key signature authorizes transaction, and Transaction Information is sent to any node of block chain network, if the Transaction Information quilt
It is legal to verify, then is broadcast to entire block chain network, until network is reached common understanding, is written into block data, takes at this time
Business node obtains the token consumption permission of accounts of consumption.
In practice, the accounts of consumption for the Program Generating that consumer side is set by " user " shown in Fig. 2 is released to certain
The mandate of one measuring terminals signs and issues metering with accounts of consumption and authorizes releasing transaction, the terminal built-in to be released is specified in transaction
Measure account.De-authorization is a transaction of the key signature of accounts of consumption, and Transaction Information is sent to any of block chain network
Node is broadcast to entire block chain network if the transaction is verified legal, until network is reached common understanding, is written into
In block data, measuring device can not continue the token of accounts of consumption at this time.
In practical applications, scrip balances transfer can be carried out between consumer, corresponding application scenarios can be consumption
Person merchandises to the remaining sum of consumer, can also be that (bank itself is also an accounts of consumption, only for the sale of electricity operation of bank counter
One agency of power supply bureau).The mode of operation is to initiate token transfer operation with the accounts of consumption for the side of producing, and specifies and turns in transaction
Move the accounts of consumption of target.
In implementer face, balance transfer transaction can be understood as money transfer transactions, i.e., the token that accounts of consumption A will hold
It is transferred to accounts of consumption B, the transaction is by the key signature of account A, and transaction is sent to any node of block chain network, if the friendship
It is easily verified legal, then it is broadcast to entire block chain network, until network is reached common understanding, is written into block data, this
When account A scrip balances can reduce, the scrip balances of account B can increase corresponding amount.
In practical applications, measuring terminals are deducted fees according to the power consumption of measurement to consumer.The process of realization is as follows：Rule
A fixed minimum measurement unit (such as 10kwh) calculates minimum measurement unit according to current electricity price (being provided by power supply bureau)
Corresponding token amount；Measuring terminals sign and issue metering transaction with the private key of built-in metering account, and the content of transaction is to deduct to award
The token of amount is corresponded in power account；If the transaction by network validation (terminal is authorized to, and account with power of attorney have it is enough remaining
Volume), then measuring terminals are let pass the electricity of corresponding amount (minimum measurement unit)；When corresponding amount consumption finishes soon, weigh again
The step of multiple front.
In implementer face, transaction of deducting fees is signed as the key built in measuring terminals, which has that account A's is close
Key is signed, and any node that transaction is sent to block chain network is broadcast to entire block chain if the transaction is verified legal
Network is written into block data until network is reached common understanding, and measuring terminals are awarded electricity amount at this time, and user can be with
Use corresponding electricity.
Seen from the above description, service network of the technical program metering and billing process independent of centralization, and with skill
Art rather than credit instrument ensure the authenticity of data.
