On May 6, 2017, of bit money network trade the quantity achieved the history inside a day new tall: 375, 000 trade, reach 2.5 billion dollar. And be in this a few days ago, of bit money network trade on average poundage exceeded 1 dollar first. These numbers are rising all the time: Arrive at the beginning of June, its trade on average poundage reached 5.66 dollars. This is unprecedented. Came on January 1, 2014 in 3 years of time January 1, 2017, poundage of average each deal uses bit money week to never exceed 31 cent. More than hereat. Before ending 2017, average poundage ever was as high as bit money week 48 dollars. And when should adding close currency market to come down calmly, bit money trades the quantity begins to be decreased suddenly, poundage also falls to 1 dollar the following.
The most frenzied day rises in bit money violent wind in, the poundage that discovers when average user oneself send bourse to need is compared trade when amount is higher, they trade to bit money batch processing technology (Batching, will much pen trades output incorporates odd pen trades) cry comparing allows when to be awaited before want big. David Harding is by August the rich guest article that wrote to save cost about using batch processing, turn its everyday the bit money that sticks Reddit child below edition piece.
This think of a way is very simple: the substance that sends much pen to trade to, incorporate many output odd pen Fair more province space and cost, because each deal has fixed data expense. David discovery, if you trade 10,incorporate brushstroke trades, is not to send each alone, with respect to what can save 75 ％ area piece space. By nature, batch processing is one kind will trade more as far as possible bale the area with bit finite money piece the method in the space.
When 2017 of money of the bit in year trade poundage begins to climb when rising, user people begin microscope bit money the act that the person that use spends again in area piece catenary, in order to decide they used area piece space effectively. As a whole, they are done not have -- -- an informal go canvassing activity began, these main users (basically be bourse) be used to trade by the requirement batch processing technology, in order to had used finite area piece space. Some bourses are being used all the time for years trade batch processing technology, and another some of bourse just compromises use this technology. 2018 first quarter, bit currency value from about 19, 000 dollars steep fall to 6000 dollars later, this problem disappeared, trade quantity of keep long in stock begins to be decreased suddenly, average poundage also dropped.
But we still can feel curious to this. Common view is, during the quantity trades to be decreased suddenly on catenary, trade the quantity can be used measure its area piece the effective utilization rate of catenary. And trade batch processing technology can make up accept random to measure (inside reasonable range) trade, accordingly, if batch processing technique becomes more and more popular, can be in maintain these trading that still be in to undertake while, let trade the quantity becomes opposite a few less.
Bit money trades of the quantity because,decreasing is batch processing technology, and rather than is not worth as a result of demand
A few websites appear suddenly, network of report bit money everyday output and pay a circumstance, is not to trade quantity, trade to bit money it seems that the report that the volume drops feels malcontent. However, still be opposite without the person of bit money trade quantity and output or pay the metabolic relation that exists between the circumstance to undertake beyond the mark analyse. Then ourselves seeks the solution.

4. conclusion
5. add content: UTXO is amalgamative
1. introduces batch processing technology
Bit money used UTXO model (Unspent Transaction Output) , did not cost namely trade output. Under photograph comparing, what Ripple and aether lane use is account / remaining sum model. In bit money, the user does not have remaining sum, it is OK to have only pilot UTXO. If they want to turn money to someone else, their purse can choose one or more UTXO to serve as an input (Input) , and these UXTO need to add up be equal to them to want to turn the amount that give. Next these capital can be turned to receiver (call output, output) , balance returns dispatcher (call look for 0 output, change Output) . Each output is OK with " acute hearing " (the form of Satoshi) bears the weight of almost infinite value. Acute hearing it is delegate bit money the unit of 1/100000000. The hypostatic purse of this and money of replete and different denomination is very similar. If you want to buy a snacks with 2.5 dollars, but you have a piece of 5 dollars only, you will never give the member that receive silver half pieces of 5 dollars, give the member that receive silver that piece of 5 dollars directly however, get a few pocket money then.
Some people do not know, an area piece can accommodate trade the amount is limitted without hard encode. Contrary, each deal has certain data volume, this is drive of a kind of economy, the division that makes colliers bring into its them piece. As a result of bit money size of area piece capacity has 2 MB only, data is bigger trade to pay taller poundage need. In addition, each deal can have the input of almost infinite quantity or output, trade ever had appeared to have 20 in the record, 000 inputs and 13, of 107 output trade. (compensatory: Textual did not point to issue body to trade, be as follows according to translator textual research)
So each deal has an input and an output at least, but return more other things normally, be like a few additional pattern plate files. Major space is taken up by the input (it is 60 ％ or more normally, because autograph proves they belong to dispatcher) really, and output occupies 15%~30 ％ . Make easy news to decrease as far as possible and economic poundage, bit money user has pick of two general election:
1. reduces input amount as far as possible. For the smallest change an input, in poundage low-down moment, you can send lesser UTXO yourself regularly, obtain a bigger UTXO thereby. This is so called UTXO amalgamative (amalgamative your input) .
2. often undertakes turning the user of Zhang (be in especially same area piece in) can be in the output that almost infinite amount contains in trading with brushstroke (to different person) . This is so called trade batch processing. The only output of brushstroke model trades take up 230 byte, and of two output trade to take up only 260 byte, if you send them alone,need to take up 460 byte.
This is a lot of informal observer comparing bit money of oversight of the place when with its he pays a system: It is OK that brushstroke bit money trades gather turns thousands of sums alone Zhang! Realise this are very important, because this is a lot of misunderstanding and the germ that the mistake analyses.
We never had seen contrast spy currency trades the current definition of batch processing, because of this purpose for this research, we define it with the fullest kind: Brushstroke has 3 or more outputs trade. Normally, batch processing is to basically trade the activity of efficiency with instant sex by mine pool or bourse by understanding. Average bit money user has the reason that batch processing trades rarely, and actually most purse hard compose builds batch processing to trade. To daily use, average bit money user won't go probably painfully batch processing trades.
For simple for the purpose of, we are setting of this one bounds the blame batch processing with normal 3(to trade having to trade sexual output looks for 0 output) with, but the model that comes from bourse batch processing trades have a few to be outputted hundreds of times even. Stem from this reason, we are very careful the data that the ground provides all sorts of batch processing, accordingly we can decide 3 output trade with 100 output tremendous trading epidemic.
We discover bit currency trades the postal car that counts a replete case is very helpful. Every mail-cart (trade) record a case (output) , contain in every case a few correspondence (acute hearing) . Accordingly, will trade when you when the quantity treats the target of the performance that measures bit money network and economic handling capacity, resemble know the correspondence measure that some day sends through computational mail-cart a bit, although correspondence amount may have very big difference. The analogy of mail-cart also expresses palpability clearly why the settle accounts layer that a lot of people regard bit money as future -- -- be in like mail-cart like after be fully loaded with, just setting out, somebody final bit money also meets forecast such.
Batch processing
2. time line
So what did 6 months produce after all in the past? We will view a few data. Of bit money network daily trade the volume rises steadily, till May 2017, average poundage achieved 4 dollars left and right sides. This facilitated to trade the first time of the quantity breaks down. Next, be in next in 6 months, began a series of feedback circulates: Trade quantity of keep long in stock increases, what need poundage to also increase accordingly, trade then the quantity begins to drop. 2017 second half of the year, this one loop repeats appeared 5 times.
Average poundage and trade plan of quantity change concern
The red solid line in pursueing on expresses with bit money calculative average poundage (blame dollar) , shadow red area expresses daily trade gross. You can see trade the loop of keep long in stock can bring about poundage taller, and tall poundage is brought about again trade the quantity decreases. Before alleviating till December 2018, such loop repeated 56 times. The most notable period was December 2017 ~2018 year the poundage crisis January, such poundage is calculated with bit money is quite typical actually, but of bit currency value rise meant the poundage when be being calculated with the dollar to also reach peak peak.
In November the middle ten days of a month, bit money trades when poundage reachs two digit by dollar computation, user people begin to persuade bourse consistently to use area piece space better jointly. Segregation is witnessed (Segwit) and trade batch processing (Batching) is regarded as to be useful method, can utmost ground makes bit money easy information reduce finite area piece in the space. The data that when begins batch processing to trade about bourse is very few, we collected each bourse to begin the message when batch processing trades, went to its collect in chart.
Each bourse begins to use trade the schedule of batch processing technology
The segregation that we ignored bourse to use in this analysis witnesses; with respect to batch processing character, appeal bourse is used trade the motion of batch processing technology had persuaded Bitfinex it seems that, binance and Shapeshift a few big exchange. Coinbase and GDAX also state they plan to begin batch processing to trade. Be known according to us, gemini did not allude trade batch processing technology, although we have various evidence,make clear them to had begun possibly recently to use this technology.
Accordingly some bourse are being used all the time trade batch processing technology, and some never had been used however. Whether can be this affected trade the popularity of batch processing? Let us find out the answer.
Is 3. analysed 3.1 trade does batch processing have many common?
We measure the popular level of batch processing with 3 kinds of different kind: By trade quantity, be worth by output and press sendout.
The popular level that measures batch processing (batch processing trades occupy the per cent) in trading entirely: By trade quantity, be worth by output and press sendout
(Shallow blue line: Batch processing trades quantity; Grey line: The bit currency value that batch processing outputs; Dark blue line: Batch processing sendout)
In all trading, batch processing quantity is occupied about 12% , occupy in all output 40% , output in money of all and primitive bit 30%~60% is occupied in the value. Pretty good.
3.2 as time elapse, does batch processing trade become more and more general?
From inside the chart of 3.1, we can see 3 index have small but steady ascendant trend, but we think again thorough research. So we considered to pay an amount above all (the sendout that pays someone actually, always output namely subtractive look for 0 sendout) and trade the relation between the quantity.
Bit money pays to measure and trade the relation between the quantity
Above all clearly, popular view is: Trade the volume drops is caused. Be not such, pay a quantity to also drop roughly same proportion.
From trade the quantity differentiates piece pay a quantity to make us both to this the relation between had a few knowledge.
The disbursement of each deal is measured
In our analysis, if we magnify in November 2017 up to now time limits, the disbursement that we can see each deal is measured had risen actually, from the each deal at the beginning of 2017 1.5 pay about the same nowadays 2.
The size of batch processing data of 3.3 popularity?
In below one part, we will search see size of the most popular batch processing data. To decide be batch processing what to trade, we downloaded to came in November 2017 from Blockchair in May 2018 all trading data set on bit money network.
Because poundage crisis begins truly,we choose this paragraph of period is last year in November the middle ten days of a month, meanwhile, the demand that trades to exchange batch processing also subsequently and come. So we want to catch bourse to begin the effect that batch processing trades. Of course, bigger sample book will be more significant, but our natural resources is limited, so we can begin from the example of 6 months only.
We will trade to be in group " batch processing " and " blame batch processing " group, of batch processing group trade have 3 or more output.
(X-axis is ordinal: Batch processing, blame batch processing, gross
Cross axle is ordinal: Trade value of quantity, input quantity, sendout, output)
Next, we are based on them the bit money total sendout during 6 months, trade batch processing cent becomes roughly same group. We use the measurement that chooses batch processing without the hand, we are in be based on trade the according to batch processing size on the foundation of value becomes these appearance one's duty equal part. It is our final result below:
(X-axis is ordinal: Be not batch processing, small-sized, medium-sized, large, oversize
Cross axle is ordinal: Batch processing size (output) , trade the sendout of the value of quantity, sendout, output, output value of each deal, each deal)
The total output value of all batch group during this is almost same, but they during this trade quantity and sendout are disparate however. Ask an attention, during these 6 months only 183, 108 " oversize " batch processing (contain 41 or more output) , but the output value that these batch processing have 23 million output and money of 300 thousand bit however.
Ask an attention, the output value below this kind of circumstance is to point to primitive or without adjustment data. To us, calibration searchs 0 with promiscuous output be special difficulty, so we are " probably " estimation.
During sample book reading in light of us of all sorts of batch processing size trade quantity:
What differentiate by batch processing size is daily trade quantity
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
Differentiate by batch processing size, batch processing trades trade the quantity is occupied than
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
Trade with blame batch processing the quantity is compared, batch processing trades the quantity is increasing steadily, although the largest part is small-sized batch processing (3 output) to 5. The data of sendout is provided more inspire a gender. Although batch processing trades,the quantity occupies whole to trade only the one part with quite small amount, but they included a large number of significant output. Let us look how to decompose them:
Press the sendout that batch processing size differentiates
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
Sendout of all sorts of batch processing size are occupied than
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
Finally, we will see output be worth. We see batch processing trades is a substantial that bit currency value transmits.
The bit money that differentiates by batch processing size always exports a worth
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
The output value of all sorts of batch processing size is occupied than
(Bottom label is ordinal: Batch processing of oversize, large, medium-sized, small-sized, blame trades quantity)
What we see no less than, although batch processing trades to be occupied on average only,always trade the 12 ％ of the quantity, but the 30 ％ that they occupy all bit money to export a worth however - 60 ％ , achieved 70 ％ even. We think this is very marvelous. Remember please, "Total output " data did not search because of considering 0 revise; with promiscuous output that is to say, this is without adjustment primitive data. Accordingly, the ideal approximation that total output value is not gross of economy of bit money network.
3.4 trade whether does the quantity become the fluky target that scales bit money to use an amount because of batch processing?
Yes. We encourage any analysts, investor, reporter and developer strongly to begin oversight to trade purely from now quantity. The acquiescent index that measures bit money performance should be " daily pay an amount " is not to trade quantity. This also makes area piece catenary provides bit money and other UTXO more can compare a gender. The disbursement that they are having marked change normally trades than, because this requires attention only,pay an amount can. (Expect please: Coinmetrics will roll out relevant tool very quickly, so that achieve this one goal as soon as possible. )
Normally, the economic value that we think to travel on the network is to reflect the feature with its economy the mainest gross. The data after was not adjusted and be being adjusted deserves a consideration. Primitive output is worth calibration still is an art is not science, the optimal practice related its still is in development. Same, coinmetrics is developing source tool actively to realize calibration.
Conclusion
We reviewed bit money one year of in the past afresh, revealed should trade the pool is embraced when can'ting bear, community begins to search the method that can use area piece space more effectively. Spend an user to weighing for, attention falls very quickly in trade on batch processing, be about to many output are amalgamative the practice that trades for brushstroke. How is we revealed batch processing working on technical level, and each are big bourse is when to begin to use this technology.
Nowadays, in all trading, bit money network has 12 ％ about is batch processing trades, occupy the 40 ％ of all output about, the 30~60 ％ that occupies all trading to be worth. Bit money is such diminutive trades the economic force that if this is big,has, fact of this be related lets us be full of a hope, bit money still has very large development space, if use an amount,continue especially if the trend rises.
Finally, notable is, as a result of,the addition that batch processing of bit money network trades may not be completely bourse, however its are behaved in what the heat inside a few months dropped in the past. Trading as a result of batch processing is normally by large " mining industry " if the company is bourse, promiscuous business, pay processing business and mine pool to send, and blame batch processing trades to be sent by average user normally, because of this batch processing / rate of blame batch processing also is to measure a when on average how many average user uses bit money main index. From bit money since slump in price, the individual of bit money makes dosage drops likely, and " mining industry " use quantity still keeps driving. This is only guess, but also be a kind of explanation to this kind of circumstance.
On the other hand, mining industry company appears more serious ground is being acted rare be short of controller of area piece space. This is a major good news to bit money network, and be its history develop extremely last time. If this kind of managing culture can get supportive, can contain more number bit money according to compressing in area piece space, and did not come in what can foreknow, every user aux will be able to runs bit money complete node quite. We think this is a very positive development. Segregation of support of go canvassing bourse is witnessed and trade the member of bit money community of batch processing should feel proud for oneself.
Add content: UTXO is amalgamative
Still remember us saying, save in ground of in an orderly way of bit money network trade is the 2nd kind of method of poundage need in place incorporate when is poundage inferior your UTXO? Observation input is measured and the relation between sendout can let us discover this kind of amalgamative opportunity well.
The input estimates figure of sendout relation change
(Blue line: Trade quantity; Red line: Sendout; Green line: Input quantity)
Normally, input and the athletic line that output change are consistent. And embrace when bit money network when blocking up, they can depart. If examine the chart above carefully, you can notice should trade the volume rises (poundage excessive price) when, sendout exceeded input amount, look to was mixed in May 2017 the difference December. But, so abiding activity always can bring about UTXO fragment to change be full of dust pocket money with purse, need undertakes incorporating. For this, the user wants normally when network pressure is reduced, poundage reduces ability to undertake operating. Accordingly, in trade after the volume drops, the input will be commonner than output. You can be in 2017 Feburary, saw this clearly in March.
Input quantity exceeds sendout
We had been calculated here the rate that gave input and output (it is with 7 days fiducial undertook flowing processing) . Become when rate is higher, input quantity of that day exceeds sendout, vice versa. You can see clearly, in the dust attack Spring 2015, thousands of (the likelihood is millions) output is founded, be incorporated next. Once this rate rises, begin to incorporate. After 6 weeks of tall in December 2017 poundage pass, the peak value Feburary 2018 is the most apparent relaxation on bit money history period; this is throughout history input / of output the biggest deviate. Many UTXO is incorporated.
The position that notices input and output gather is very significant also. Be a large number of inputs and output below trade histogram. As expected, the frequency that integral output input appears second very tall, this shows bourse won't be sent two minutes every trade, wait to be discharged however 100 or 200 output what just send them to trade. Strange is, during this, of 200 inputs trade to be inputted than 100 trade more popular.
The input is measured (left) with sendout (right) frequency second contrast
