The side of being transferred to of first block chain trading activity may include a certain number of privacy accounts and a certain number of non-hidden
Private account, no matter for which type of account, the amount of money that the present embodiment can obtain the side of being transferred to by step S210 is promised to undertake.It can
Choosing, for the side of being transferred to for non-privacy account: a2It is zero.
In other embodiments of the present invention, method shown in Fig. 2 can also include: to obtain the first block chain trading activity
The corresponding amount of money of service charge promise to undertake.On this basis, step S300 shown in Fig. 2 can specifically include: by each side of being transferred to
The amount of money promise to undertake and the corresponding amount of money of the service charge is promised to undertake and is added, obtain total amount and promise to undertake；The gold of the side of producing described in determination
Whether volume promise is equal with total amount promise, if equal, determines the transaction amount of the first block chain trading activity
It is legal.
The embodiment considers service charge, therefore is more in line with actual conditions.
Optionally, block chain transaction verification method provided in an embodiment of the present invention can be applied to what the transaction of block chain generated
In the process.For convenience of understanding, Fig. 4 and two kinds of block chains shown in fig. 5 transaction generation method is described below.Block chain shown in Fig. 4
Transaction generation method is block chain transaction generating process when producing Fang Weifei privacy account.The transaction of block chain shown in Fig. 5 generates
The block chain that method is the side of producing when being privacy account is traded generating process.
It is understood that ACCOUNT account can be non-privacy account, and UTXO account can in an alternative embodiment
Think privacy account.For a user, ACCOUNT account and UTXO account can be possessed simultaneously.The ACCOUNT account of user
Family can have the non-privacy account of plaintext, and UTXO account can have multiple and different privacy accounts.
The generation method as shown in figure 4, a kind of block chain provided in an embodiment of the present invention is traded, comprising:
S601, use the ACCOUNT account of user as the side of producing.
Wherein, the status informations such as remaining sum of ACCOUNT account are disclosed to third party.
Whether S602, the verification side of being transferred to are legal.If legal, S603 is thened follow the steps, otherwise determines transaction failed regeneration.
The whether legal process in the above-mentioned verification side of being transferred to may include: whether verification transfer amounts are greater than 0, verify the side of being transferred to
Account whether be preset length.
Wherein, the length of the privacy account of privacy account legal in the present embodiment is 95 bytes, legal non-privacy
The length of the non-privacy account of account is 42 bytes.When the length of the account for the side of being transferred to is not above-mentioned two byte length,
It can determine that the account for the side of being transferred to is illegal.
S603, service charge is calculated.
The present embodiment can be distinguished commonly to transfer accounts and be called with contract.If it is commonly transferring accounts, the present embodiment will be according to producing
The certain proportion of the amount of money collects service charge, and upper limit value can be arranged, and is not further added by then more than the upper limit.It is called if it is contract,
Then service charge is made of two parts, and a part is to collect the certain proportion for producing the amount of money, and a part is contract executive proceeding expense, this
This two parts can be added together the service charge called as contract by embodiment.
S604, check ACCOUNT account remaining sum whether enough payment produce the amount of money and service charge, if insufficient, transaction
Failed regeneration.If enough, thening follow the steps S605.
S605, the encapsulation non-privacy side of producing object, trade the non-privacy side of the producing object as the first block chain only
One side of producing.
The transaction of first block chain can be primary block chain trading activity, such as: according to contract, A was in some of certain day
Carve the ideal money for being respectively transferred to certain number to B, C, D respectively.Then this time A is transferred to the process of ideal money i.e. to B, C, D respectively
For a block chain trading activity.
Wherein, which may include following information: nonce value produces total value, amount of money promise and mixes
Confuse the factor.Wherein, nonce value is any or non-repetitive random number being only only used once in cryptography, can be with
It directly inquires and obtains from block chain.It produces total value and produces the sum of the amount of money and service charge for the transaction of block chain.
Much information can be encapsulated as object according to certain data structure by the present embodiment, so that object is sent to block
Catenary system carries out trading processing.Optionally, the side's of being transferred to object and the side's of producing object can be generated in the present embodiment.Optionally, step
The value that the amount of money in the non-privacy side of the producing object that S605 is encapsulated is promised to undertake is sky, and the value of confounding factors is also empty.
The present embodiment can will produce the amount of money and be added with service charge, and obtain the side of producing produces total value, according to formula C1=a1
×G1+b1×H1Calculate the amount of money promise of the side of producing described in obtaining, the C1It is promised to undertake for the amount of money of the side of producing, a1It is
One confounding factors, the b1For the total value that produces of the side of producing, the G1With the H1It is preset constant.
Due to not obtaining the value of confounding factors when step S605 is executed also, the side of producing also can not just be calculated
The amount of money is promised to undertake.To the present embodiment step S608 and step S609 obtain each privacy side of being transferred to of the first block chain transaction obscure because
After son, the confounding factors of each privacy side of being transferred to can be added by step S612, using calculated result as the confounding factors for the side of producing.
Formula C can thus be passed through1=a1×G1+b1×H1The amount of money that the side of producing is calculated is promised to undertake.
The non-privacy side of the producing object can be indicated with AccountInput object.
Respectively whether the side of being transferred to has encapsulated for S606, judgement.If encapsulated, step S612 is gone to, otherwise, after
Continuous step S607.
It is understood that the transaction of the first block chain can have multiple sides of being transferred to, present invention needs are transferred to Fang Jun to each
It is packaged.
One S607, selection unencapsulated side of being transferred to, judge the privacy type of the side of being transferred to.If the side of being transferred to is privacy account
Family then goes to step S609, if being non-privacy account, thens follow the steps S608.
Specifically, the present invention can determine that it be privacy account is also non-privacy account according to the length of the account for the side of being transferred to
Family.Specifically, the side of being transferred to is privacy account when the length of account is 95 bytes, when the length of account is 42 bytes,
It is transferred to Fang Weifei privacy account.Wherein, comprising spending public key and view public key in the privacy account of privacy account.
S608, the encapsulation non-privacy side of being transferred to object, be transferred to side of the non-privacy side of the being transferred to object as the first block chain.It
Go to step S606 afterwards to continue with the unencapsulated side of being transferred to.
The non-privacy side of the being transferred to object may include following information: the non-privacy account for the side of being transferred to is transferred to the amount of money and the amount of money
It promises to undertake.
Wherein, it is transferred to amount of money exposure (in plain text).The present invention can be according to formula C2i=a2×G2+b2i×H2It calculates separately
The amount of money for obtaining each side of being transferred to is promised to undertake, wherein the i is the number of the side of being transferred to, and i is nonnegative integer, the C2iFor
The amount of money promise for the side of being transferred to that number is i, a2For the second confounding factors, the b2iIt is to be transferred to described in i for number
Side is transferred to the amount of money, the G2With the H2It is preset constant.
Optionally, for the side of being transferred to for non-privacy account: a2It is zero.
Wherein, the non-privacy side of being transferred to object can be indicated with AccountOutput object.
S609, it parses the view public key (PV) in the account of privacy account and spends public key (PS).According to formula addr
=H ' (r*PV, i) G3+ PS, which is calculated, obtains disposable account address addr.Gold is transferred to according to formula key=H " (r*PV, i) calculating
The encryption key of volume.Continue step S610 later.
Wherein, H ' is the first hash function, and i is the number for being transferred to object that the transaction encapsulation of the first block chain obtains, G3For
Constant, H " are the second hash function, and R is to preset random public key, and r is default random private-key.
The present invention can calculate the confounding factors for obtaining privacy account according to key.Specifically, the present invention can be according to function
Key is mapped as confounding factors by mapping, such as: by key multiplied by a coefficient after, obtain confounding factors.
S610, the encapsulation privacy side of being transferred to object, be transferred to side of the privacy side of the being transferred to object as the first block chain.
Wherein, the privacy side of being transferred to object may include: that disposable account address and the amount of money are promised to undertake.
Wherein, the present embodiment can be according to formula C2i=a2×G2+b2i×H2It calculates separately and obtains each side of being transferred to
The amount of money is promised to undertake, wherein the i is the number of the side of being transferred to, and i is nonnegative integer, the C2iIt is the side of being transferred to described in i for number
The amount of money promise to undertake, a2For confounding factors, the b2iTo number the amount of money that is transferred to for being the side of being transferred to described in i, the G2And institute
State H2It is preset constant.
The privacy side of being transferred to object can be indicated by UTXOOutput object.
S611, it is based on bulletproofs algorithm, the section that calculating is transferred to the amount of money proves.Use what is generated in step S609
Encryption key is transferred to amount of money encryption in the non-privacy side of the being transferred to object of the encapsulation in step S608, obtains the encryption amount of money, protects
Deposit the encryption amount of money.Step S606 is gone to later.
S612, the confounding factors according to each side of being transferred to, calculate the confounding factors for the side of producing, pass through formula C1=a1×G1+b1
×H1The amount of money that the side of producing is calculated is promised to undertake and is filled in the non-privacy side of the producing object encapsulated to step S605.
S613, according to the account of non-privacy account and the cryptographic Hash of at least one Transaction Information, calculated based on elliptic curve
Method, which calculates, obtains non-privacy account signature.
Wherein, the Transaction Information can be with are as follows: remaining sum is transferred to the amount of money etc..
Wherein, non-privacy account signature can be signed with ACCOUNT and be indicated.Non- privacy account signature can be used in block
Whether verifying transaction initiator is legal in chain process of exchange.
S614, it each object of encapsulation is sent to block catenary system trades.
By each step shown in Fig. 4 it is found that the present invention can obtain the side of producing in block chain transaction generating process and turn
The amount of money for the side of entering is promised to undertake, is then respectively put into the side's of the producing object and the side's of being transferred to object of encapsulation.In this way, each when what is encapsulated
Object is sent to block catenary system when being traded, and block chain is assured that in the side's of producing object of the first block chain transaction
The amount of money promise to undertake whether with the first block chain transaction the respectively side of being transferred to object in the amount of money promise to undertake the sum of it is equal, and then determine transaction be
It is no legal.
As shown in figure 5, another kind block chain transaction generation method provided in an embodiment of the present invention, may include:
S701, use the specified privacy account of user as the side of producing.
Wherein, the information such as remaining sum of privacy account are unknowable to third party.Privacy account can be UTXO account.
Whether S702, the verification side of being transferred to are legal.If legal, S703 is thened follow the steps, otherwise determines transaction failed regeneration.
Whether legal it specifically can be the contents such as verification transfer amounts, the side of being transferred to address.
S703, service charge is calculated.
If it is commonly transferring accounts, service charge will be collected according to fixed value, this fixed value is arranged by special contract.If it is
Contract calls, and other than collecting fixed fee, can also be accumulated in the service charge consumed in contract implementation procedure.
S704, check the side's of producing account remaining sum whether enough payment produce the amount of money and service charge, if insufficient, transaction life
At failure.If enough, thening follow the steps S705.
Wherein, step S702 to step S704 is similar to step S604 to step S602 shown in Fig. 4, is no longer described in detail.
S705, privacy account team is obtained to the progress descending sort of these privacy accounts according to the remaining sum of each privacy account
Column.It is subsequent when selecting UTXO, preferentially select the UTXO of the privacy account of high remaining sum.
S705 is optional step.
S706, judge whether all sides of being transferred to all have encapsulated.If all encapsulated, step S715 is gone to, otherwise,
Continue step S707.
One S707, selection not used UTXO.One is preferentially randomly choosed from the UTXO of the privacy account of high remaining sum.
S708, judge whether all sides of being transferred to all have encapsulated again.If encapsulation finishes, step S715 is gone to, otherwise,
