A kind of transaction fee predictor method provided in an embodiment of the present invention is introduced first below, the embodiment of the present invention mentions
A kind of transaction fee predictor method supplied, as shown in Figure 1, including the following steps.
S101 determines that the target to be transacted for target token is handed over according to the transaction record of target token in ether mill
Easily unit price.
Wherein, target token can be user on ether mill it is customized building distribution, target token can for based on
The token of ERC20 agreement can also be the token based on ERC23 agreement.Target token can for ZCash, Lay spy coin,
Any one of tokens such as Monero, Gnosis, Augur.
The each token transactions occurred in ether mill can be recorded, and can be synchronized to included by ether mill and own
Node, in this way, each of ether mill node is stored with the transaction note of each token transactions occurred in the ether mill
Record.Specifically, when a token transactions A has occurred in the node A in ether mill, then node A will record token transactions A, and
The token transactions A recorded is synchronized in ether mill other nodes in addition to node A, in this way, each of ether mill
Node is stored with the transaction record of token transactions A.
Token may include multiple types, and the transaction record in ether mill can be divided according to token type in ether mill
Class storage, the corresponding classification of each token.For example, transaction record caused by Gnosis token transactions is stored in and is directed to
In the transaction record of Gnosis token.
According to the transaction record for target token completed in ether mill, can calculate flat based on transaction record
Transaction unit price, can be by the transaction unit price of the average transaction unit price as current goal token, i.e., by the average transaction unit price
As target transaction unit price to be transacted.
In a kind of embodiment, from the transaction record for target token that ether mill is stored, preset friendship is obtained
The easily corresponding transaction record of duration grade.
Wherein, it will record the duration that corresponding transaction is spent in each transaction record.For example, target token transactions A
Recorded in corresponding transaction record a when it is 10 minutes a length of, then it represents that target token transactions A complete the exchange cost
Shi Changwei 10 minutes.
Transaction duration grade, which refers to, completes the grade that spent duration divides according to transaction, the division for duration grade of trading
It can be customized setting.For example, transaction duration grade is divided into four grades, the first estate is to complete to hand within 10 minutes
Easily, the second grade is the transaction of completion in 10 minutes to 20 minutes, and the tertiary gradient is the transaction of completion in 20 minutes to 30 minutes, the fourth estate
It is that the completion more than 30 minutes is needed to trade.When trade B transaction record in when it is 12 minutes a length of, then corresponding to transaction B
Transaction duration grade is the second grade.
Acquisition for transaction record in a kind of implementation, can obtain transaction from any node in ether mill
Record.In another implementation, the transaction record of target token can be obtained from default node included by ether mill.Its
In, default node can be customized setting.For example, in order to improve the confidence level with higher of acquired transaction record
And accuracy, default node can be the third party's node for having higher public credibility, wherein the public credibility of node can be user's root
According to determined by experience.
After getting transaction record from default node, preset time period can be chosen from acquired transaction record
Transaction record corresponding to interior transaction duration grade.Wherein, preset time period can be customized setting.For example, default
Period is one day, then the transaction record stored in the time before choosing current point in time.
For example, preset time period be 30 minutes, from the current point in time that default node is got before 30 minutes in institute
The transaction record of storage includes transaction record 1, transaction record 2, transaction record 3, transaction record 4, transaction record 5 and transaction record
6, wherein when 8 minutes a length of, when 12 minutes a length of, 3 institute of transaction record that transaction record 2 is recorded that transaction record 1 is recorded
Record when it is 18 minutes a length of, transaction record 4 recorded when it is 28 minutes a length of, transaction record 5 recorded when it is 15 points a length of
Clock, transaction record 6 recorded when it is 6 minutes a length of.In addition, transaction duration grade includes the first estate and the second grade, wherein
The first estate is that transaction is completed within 10 minutes, and the second grade is the transaction of completion in 10 minutes to 20 minutes.Then the first estate institute is right
The transaction record answered includes：Transaction record 1, transaction record 6, transaction record corresponding to the second grade include：Transaction record 2,
Transaction record 3 and transaction record 5.
After obtaining the corresponding transaction record of preset transaction duration grade, based on acquired transaction record, determine
The corresponding transaction unit price of each transaction duration grade.
Record has real trade expense and practical calculation amount in each transaction record.Wherein, real trade expense refers to completion
Transaction fee caused by the transaction reality of target token, calculating needed for practical calculation amount refers to the transaction for having executed target token
Amount, calculation amount may be considered amount of action performed in process of exchange, wherein calculation amount is measured with gas.
Duration grade of trading calculates separately the transaction unit price of each transaction record when being corresponding at least one transaction record,
The transaction unit price of comprehensive at least one corresponding transaction record again, it can obtain the corresponding trading card of transaction duration grade
Valence.
In a kind of implementation, after determining transaction record corresponding to each transaction duration grade, each is obtained
Included real trade takes and practical calculation amount in transaction record corresponding to transaction duration grade.For each transaction note
Record can be taken with the real trade in transaction record divided by practical calculation amount, the available trading card for the transaction record
Valence.
For example, transaction duration grade in the first estate corresponding to transaction record include transaction record 1 and transaction record
2, wherein it is 20000Gwei that real trade, which takes, in transaction record 1, and practical calculation amount is 20000, then is directed to the friendship of transaction record 1
Easily unit price is 1Gwei, is indicated in the transaction corresponding to transaction record 1, and the cost of each Gas unit is 1Gwei.Wherein,
Gwei is a unit for indicating an ether coin, and 1Gwei is approximately equal to 0.00000002 ether coin.
It, can for the corresponding transaction unit price of transaction duration grade after the transaction unit price for calculating each transaction record
To be divided into following three kinds of situations.
The first situation, a transaction duration grade only correspond to a transaction record.Then directly by the friendship of the transaction record
Easy unit price is determined as the corresponding transaction unit price of the transaction duration grade.
For example, transaction record corresponding to the first estate in transaction duration grade only includes transaction record 1, transaction note
The transaction unit price of record 1 is 1Gwei, then the corresponding transaction unit price of the first estate is 1Gwei.
Second situation, a transaction duration grade are corresponding at least two transaction records.By at least two transaction note
The transaction unit price of record carries out average computation, obtains average transaction unit price.
Specifically, average transaction unit price can be calculated according to following formula：
Wherein, Q is average transaction unit price, and n is the quantity of transaction record corresponding to transaction duration grade, piWhen to trade
The transaction unit price of i-th of transaction record, p in transaction record corresponding to long gradenFor transaction record corresponding to transaction duration grade
In n-th transaction record transaction unit price.
After obtaining average transaction unit price, which can be determined as trading corresponding to duration grade
Transaction unit price.
The third situation does not consider the transaction duration grade if transaction duration grade does not have corresponding transaction record.
After determining the transaction unit price of each transaction duration grade, it can be chosen from identified transaction unit price
One transaction unit price, as the target transaction unit price to be transacted for target token.
Specifically, each transaction duration grade is corresponding with a transaction unit price, and transaction duration grade reflects target generation
The speed of coin transaction, it is believed that target token transactions the time it takes is fewer, and the speed of target token transactions is faster, mesh
Mark token transactions duration higher grade.In general, transaction duration higher grade, and corresponding transaction unit price is higher；When transaction
Long lower grade, and corresponding transaction unit price is lower.
Based on the relationship between above-mentioned transaction duration grade and transaction unit price, each transaction duration grade is being determined
After transaction unit price, each the transaction unit price determined is shown to user, is selected wherein by user according to own situation
One transaction unit price is as target transaction unit price to be transacted.If selecting higher transaction unit price, processed speed to be transacted
Degree is very fast, and the time it takes is less, but higher for the spent transaction fee to be transacted；If selecting lower trading card
Valence, then in transaction to be processed is lined up it is to be transacted can be lined up relatively after, in this way, processed speed to be transacted is slower, cost
Time is longer, in addition due to transaction unit price it is low cannot be processed and lead to Fail Transaction.
S102, building be directed to target token mock trading order, and in ether mill to mock trading order at
Reason.
Wherein, the turnover of the constructed mock trading order for target token is identical as turnover to be transacted.
Turnover is the amount of money involved in process of exchange, and technical solution provided by the embodiment of the present invention is the friendship for target token
Easily, therefore turnover is measured with target token.For example, target token is Lay spy coin, user A needs to pay 4 Lays to user B
Special coin, then this time the turnover of transaction is 4 Lay spy's coin.
Wherein, the transaction unit price of mock trading order is target transaction unit price.The calculation amount upper limit of mock trading order is
Preset upper limit value.
Wherein, the calculation amount upper limit can be customized setting.Used calculation amount is not up to counted when the transaction is complete
Remaining calculation amount can then be returned to the founder of the personnel for initiating transaction or intelligent contract by the calculation amount upper limit.Work as transaction
When used calculation amount reaches the calculation amount upper limit when not completing also, then it can shut the book, lead to Fail Transaction.For transaction
The calculation amount upper limit, if setting is too low, it is believed that the transaction is invalid.
The calculation amount upper limit for mock trading order is preset upper limit value, can be customized setting.On this is default
As long as limit value is arranged sufficiently low so that the mock trading order may be considered that in vain, then the preset upper limit value be all can
Capable.
Complete construct mock trading order after, the mock trading order is handled in ether mill, i.e., with
The transaction to the mock trading order is initiated too in mill.
S103 estimates transaction fee to be transacted according to the feedback result of mock trading order.
Mock trading order is considered invalid because preset upper limit value is lower, for the mock trading order
Trade fair Fail Transaction.It, can be to the creation of the user for initiating transaction or intelligent contract after the failure of mock trading order transaction
Person sends feedback result, wherein feedback result can be transaction fee, can also be calculation amount.Separately below with regard to two kinds of situations into
Row is introduced.
When feedback result is transaction fee, which is for transaction fee caused by mock trading order transaction.From
The transaction fee that the mock trading order is extracted in the feedback result of mock trading order, the transaction based on the mock trading order
Volume, transaction unit price, calculation amount are identical as turnover to be transacted, transaction unit price, calculation amount, it is believed that the mock trading
Transaction fee needed for order is identical as required transaction fee to be transacted, therefore, extracted transaction fee can be determined as wait hand over
Easy transaction fee.
When feedback result is calculation amount, which is calculation amount needed for mock trading order completes transaction.From mould
The calculation amount that mock trading order is extracted in the feedback result of quasi- trade order, turnover, friendship based on the mock trading order
Easily unit price, calculation amount are identical as turnover to be transacted, transaction unit price, calculation amount, it is believed that the mock trading order institute
The calculation amount needed is identical as required calculation amount to be transacted, therefore, extracted calculation amount can be determined as to mesh to be transacted
Mark calculation amount.
After determining target calculation amount to be transacted, target calculation amount is multiplied with target transaction unit price, obtain to
The transaction fee of transaction, i.e., according to the available transaction fee to be transacted of following formula：
F=G × P
Wherein, F is transaction fee to be transacted, and G is target calculation amount, and P is target transaction unit price.
In technical solution provided in an embodiment of the present invention, according to the transaction record of target token in ether mill, determination is directed to
The target transaction unit price to be transacted of target token, building are directed to the mock trading order of target token, and right in ether mill
Mock trading order is handled, and according to the feedback result of mock trading order, estimates transaction fee to be transacted.Through the invention
The technical solution that embodiment provides estimates current target transaction unit price, structure using completed token transactions in ether mill
It builds and trades and turnover to be transacted and the identical mock trading order of transaction unit price, according to the feedback knot of mock trading order
Fruit estimates transaction fee to be transacted, and the transaction fee estimated can provide reference to initiate user to be transacted, so that handy
Family provides suitable transaction fee to be to be transacted, Fail Transaction caused by avoiding transaction fee excessively high.
