In an embodiment of the present invention, it is described the transaction successful information is recorded in the block chain after, into
One step includes：
Obtain the corresponding block abstract of the block chain；
Block abstract is sent to the corresponding main block chain of the block chain.
In an embodiment of the present invention, it is made a summary by the corresponding block of calculation block chain, i.e. cryptographic Hash, so as to which block is plucked
Block abstract is sent to main block chain, can make each area in main block chain as the unique mark of block chain
Block chain is reached common understanding, so that main block chain memory block is made a summary, and uses the side of main block chain and block chain (i.e. lateral areas block chain)
On the one hand formula can reduce the carrying cost of block chain, on the other hand can also improve the efficiency that block chain is reached common understanding.
It is right below by taking seller m and block chain q as an example in order to which what is be more clear illustrates technical scheme of the present invention and advantage
A kind of method of commerce based on block chain provided in an embodiment of the present invention is described in detail, as shown in Fig. 2, can specifically include
Following steps：
Step 201：Pre-set intelligent contract, the supervision information of signature and supervision public key are recorded in block chain q.
Specifically, pre-set intelligent contract is a promise (i.e. transaction rule that multi-party users are participated and draw jointly
Then), the rights and duties of both parties are contained in promise；
In addition, with electric power major network detection program, electric power major network load range, electricity transaction price, both parties' transaction
The supervision information of distance avoids the transaction value of both parties too high or too low so that the transaction to both parties constrains
And trade market is upset, and determine whether information on bidding meets the electrical power demand of electric power major network；
In addition, regenerating asymmetric administrative key pair, that is, supervision public key and supervision private key are generated, to believable third party CA
The public key certificate of authentication center's application supervision public key generates the supervision information of signature using supervision private key to supervision Information Signature,
So that dealing user obtains supervision public key by supervising public key certificate, the supervision information of signature is verified by supervising public key, no
The authenticity of public key can only be supervised, moreover it is possible to supervision information be avoided to be tampered.
Further, since the data that the characteristic of block chain is record can not be deleted, be changed, can only increase newly, therefore, by intelligent conjunction
About, supervise information, supervision public key certificate be recorded in block chain q, it is ensured that history traces, and avoid centralization because
The influence of element.
For example, asymmetric administrative key pair is generated using SM3 national secret algorithms, using in asymmetric supervision secret key pair
It supervises private key to sign to pre-set intelligent contract, by the intelligent contract of signature, supervision information and asymmetric administrative key pair
In supervision public key be recorded in block chain q.
Wherein, intelligent contract is that the information on bidding sent according to seller determines corresponding winning bidder (i.e. buyer), in determination
The seller is needed to need transaction item being sent to winning bidder and winning bidder and needed after receiving transaction item to seller after winning bidder
Send transaction money；
It supervises in information and detects 0.5 yuan -1.2 yuan/watts of program and pricing range for electric power major network, distance range of merchandising
For Jinan City.
Step 202：Seller m is received according to the intelligent contract, supervision information and the supervision public key that are recorded in block chain q, is sent
Information on bidding and seller's public key.
Specifically, the information on bidding and seller's public key received is by the supervision public key that seller m is recorded according to block chain q
After certificate acquisition to supervision public key, the supervision information by supervising public key decryptions signature can be obtained decryption supervision information, then will
Decryption supervision information, which is written to, to be formulated according to intelligent contract in the intelligent contract of bid, finally by asymmetric seller's private key of generation
To including the information on bidding signature of the intelligent contract of bid.And seller's public key is utilized to sign information on bidding, it can be at other
When user obtains the information on bidding of signature, the information on bidding of signature is verified using seller's public key, so as to determine that information on bidding is
It is no to be tampered.
For example, the information on bidding and seller's public key G that seller m is sent are received.Wherein, information on bidding has been signed, and
It is including the intelligent contract of bid：Address is 5000 watts of the areas A of Jinan City electricity, electricity price is 0.5 yuan/watt.
Step 203：Determine whether seller's public key can decrypt information on bidding.
Specifically, it after the information on bidding and seller's public key for receiving signature, needs to verify bid using seller's public key
The validity of Information Signature, so as to determine whether information on bidding is tampered.
For example, the validity of seller's public key G verification information on bidding signatures is utilized, it is determined whether bid letter can be decrypted
Breath.
Step 204：When seller's public key can decrypt information on bidding, block chain q is recorded in information on bidding and seller's public key
In.
Specifically, after determining the validity of information on bidding signature, you can determine that information on bidding is not tampered with, therefore can be with
Information on bidding and seller's public key are recorded in block chain.
For example, after the validity for determining information on bidding signature, block is recorded in information on bidding and seller's public key G
In chain q.
Step 205：At least one buyer is received according to intelligent contract, information on bidding and seller's public key, the bid of transmission is believed
Breath and buyer's public key.
Specifically, the bid information and buyer's public key received be by, buyer according to the block chain q intelligent contracts recorded and
After information on bidding using seller's public key decryptions signature, the bid intelligence contract of formulation, then it is private by the asymmetric buyer of generation
Key signs to the bid information including intelligent contract of submitting a tender.And buyer's public key is utilized to sign bid information, it can be at it
When his user obtains the bid information of signature, the bid information of signature is verified using buyer's public key, so as to determine bid information
Whether it is tampered.
For example, the information on bidding a being signed that buyer a is sent is received, wherein information on bidding a includes intelligence of submitting a tender
About a, and submit a tender intelligence and about a are 5000 watts of electricity of purchase, tender price is 1 yuan/watt；
The information on bidding b being signed and buyer's public key b that buyer b is sent, wherein information on bidding b includes intelligence of submitting a tender
About b, and submit a tender intelligence and about b are 5000 watts of electricity of purchase, tender price is 0.8 yuan/watt.
Step 206：For each buyer, determine whether buyer's public key that buyer sends can decrypt bid information.
Specifically, it after the bid information and buyer's public key for receiving signature, needs to submit a tender to verify using buyer's public key
The validity of Information Signature, so as to determine whether bid information is tampered.
For example, using the validity of buyer's public key a verification information on bidding a signatures, it is confirmed whether that bid letter can be decrypted
Cease a；
Using the validity of buyer's public key b verification information on bidding b signatures, being confirmed whether can secret information on bidding b.
Step 207：When determining that buyer's public key can decrypt bid information, block is recorded in buyer's public key and bid information
In chain q.
Specifically, after determining the validity of bid information signature, you can determine that bid information is not tampered with, therefore can be with
Bid information and buyer's public key are recorded in block chain.
For example, after the validity for determining information on bidding a and information on bidding b signatures, by information on bidding a, Mai Jiagong
Key a, information on bidding b and buyer's public key b are recorded in block chain q.
Step 208：Using in information on bidding decryption supervise information, determine information on bidding whether the load with electric power major network
Information is corresponding.
Specifically, it after receiving the bidding information of both parties, needs to examine using the electric power major network in information on bidding
Ranging sequence, detects whether the intelligent contract of bid in information on bidding meets the information on load of electric power major network, circuit information, major network
Power condition, avoid seller m auction electric energy cannot meet in terms of circuit, time or electric load electric power major network requirement and
Lead to not merchandise.
For example, the power monitoring program in information is supervised using decryption, determines whether information on bidding can meet at this time
The burden requirement of electric power major network.
Step 209：When determining that information on bidding is corresponding with the information on load of electric power major network, recorded from block chain q
In each bid information, current bid information corresponding with bid information is determined.
Specifically, after determining that information on bidding meets electric power major network requirement, you can enter assessment of bids flow, i.e., from each bid
The bid information for meeting information on bidding is determined whether there is in information, if there is, you can determine the bid for meeting information on bidding
Information is current bid information, otherwise, stop intelligent contract, and and Fail Transaction notice is sent to each counterparty, and update and hold
Row state.
For example, in the electric energy in determining that the information on load of electric power major network at this time can convey information on bidding, comparison
The tender price of bid information a and bid information b, you can the overbid of bid information a is determined, it is thus determined that bid information a is
Current bid information, i.e. winning bidder.
Step 210：Transaction successful information is sent to the corresponding current buyer of current bid information and seller m.
Specifically, (there is current bid information corresponding with information on bidding) when there are winning bidder, you can notice
Both parties.
For example, transaction successful information is sent to buyer a and seller m, wherein transaction successful information is that bid person is to sell
Family m, winning bidder are buyer a, and the knock-down price of 5000 watts of electricity is 1 yuan/watt.
Step 211：Transaction successful information is recorded in block chain q.
Specifically, it after notifying both parties to merchandise successfully, needs Transaction Information being recorded in block chain q so as to deposit
Shelves.
For example, the successful information that will merchandise is that bid person is seller m, and winning bidder is that buyer a is recorded in block chain q.
Step 212：In block chain q, updating information on bidding execution state corresponding with each bid information respectively is
It is completed.
Specifically, in block chain q after record transaction successful information, you can determine that intelligence contract executes completion, therefore can
To update execution state in block chain q.
For example, the more execution state of new block chain q Tender Baseds information, bid information a and bid information b is complete
At.
Step 213：Obtain the corresponding block abstracts of block chain q.
Specifically, using preset digest algorithm, the cryptographic Hash of calculation block chain q, the i.e. block of calculation block chain q is plucked
It wants, so as to determine the unique mark of block chain q.
For example, digest algorithm is used as by SM3 algorithms, the block abstract of calculation block chain q is ZY.
Step 214：Block abstract is sent to the corresponding main block chains of block chain q.
Specifically, block is made a summary and is published in the common recognition network of the corresponding main block chains of block chain q as transaction, so that
Other block chains are reached common understanding, and are finally written again in main block chain.
For example, block abstract ZY is sent to each block chain in main block chain, in other block chained records
After the block abstract ZY of block chain q, block abstract ZY is sent to the storage of main block chain.
Step 215：By in transaction successful information update to the supervision information of signature, update supervision information is generated.
Specifically, after the block of block chain q abstract is sent to main block chain, then update supervision information is needed, that is, is updated
Current power trading situation, i.e. electricity transaction valence and trading volume, so as to adjust electricity price, and can be by updated supervision information
It is recorded in next block chain, so that electricity transaction can continue to execute.
For example, in successful information of merchandising, knock-down price is 1 yuan/watt, therefore will supervise the pricing model in information
It encloses and is updated to 0.8 yuan -1 yuan/watt.
