The price of Bitcoin skips 5% on the first anniversary of $ 20,000 Bull Run


Daily outings depict a more accurate economic picture of the bitcoin blockchain status as the biggest players in the bitcoin industry use techniques to reduce transaction costs, giving traders and investors an important tool on which to base their decisions. Here because.


One of the main criticisms of bitcoin is its high transaction fees. Rates were rising in mid-2017 and the inefficient and collective use of bitcoin blockcoin space has been increasingly scrutinized. Exchanges have been under pressure on batch transactions to make better use of this limited space. (Some were already doing this for years)

Bitcoin resizing problems in times of high transaction volume means that it takes more time and costs more to send bitcoins. The mempool of the digital currency (the non-confirmed Bitcoin transaction pool on the Bitcoin network) became congested in December 2017. However, many users believe that more efficient use of the network block space can alleviate such downsizing problems.


Exchanges, mixers, payment processors and mining pools are responsible for preponderance of productivity in mempool congestion periods. One way they could alleviate congestion involves "grouping". This is done by combining multiple outputs in a single transaction. Entities that send multiple transactions at once can group the outputs in a single transaction to more efficiently use block space and save them on transaction fees.

Because each transaction is delivered with an overload in the form of fixed data, if you combine 10 payments in one transaction, instead of sending them individually, you can save space. Thus, batching allows users to send multiple transactions to the blockchain.

Transactions can have a virtually unlimited number of inputs or outputs. (The record, for example, is at 20,000 inputs and 13,107 outputs) Each transaction has at least one input and one or more outputs. The input takes up most of the space because it includes the relevant digital signature. The outputs generally represent 15-30% of the space in a transaction.

Bitcoin users can keep transactions small and save money by using less input or include an almost unlimited amount of output, ie transactions with different people, in the same transaction. This last option, called batching, means that bitcoin transactions can "aggregate" thousands of individual economic transfers.

As points out, there is no concrete definition for a batch transaction. In his batching study, he defined a batch transaction with three or more outputs. Mostly pooling or mining exchanges employ batching. As Coinmetrics writes:

We find it useful to think of a Bitcoin transaction like a mail truck full of boxes. Each truck (transaction) contains boxes (exits), each of which is filled with a certain number of letters (sathi).

So when considering the transaction count as a measure of the performance and economic throughput of the Bitcoin network, it is a bit like counting the mail trucks to distinguish how many letters are sent on a given day, even if the number of letters can vary wildly.

The analogy with the truck also clarifies why many see Bitcoin as a layer of settlements – just as mail trucks are not shipped until they are full, some think that the same will ultimately be the case of Bitcoin.

The Coinmetrics data show that about 12% of all transactions on the Bitcoin network today are in batches, accounting for about 40% of all outputs and between 30-60% of all transactional values.

Each output contains instructions on where to send specific bitcoins. In a single transaction, there can be more than one output. All outputs share the combined value of the inputs where the value is the number of Satoshi (1 BTC = 100,000,000 Satoshi) that a value will be worth when requested. Each exit from a single transaction can be referenced only once by an input from a subsequent transaction. The entire combined input value, therefore, must be sent in the output.

If you want to send 25 BTC, but the input is worth 50 BTC, bitcoin creates two outputs with a value of 25 btc. An output goes to the destination and one to you (known as "change", this is essentially the sender who sends the funds to themselves).

When multiple inputs are used, more coins are usually used in a transaction. Because transactions can have multiple outputs, users can send bitcoins to more than one recipient in a single transaction. Similar to a cash transaction, the sum of inputs – which represent the coins used to pay – exceeds the expected sum of payments. When this happens, an additional output is used, returning the change to the payer. The satosh input not included in the transaction outputs becomes the transaction fee.

Outputs per day

The phenomenon of batching has led to websites such as Output. Today it tracks "output per day", stating that it is a "better indicator of the overall economic activity on the bitcoin blockcoin compared to daily transactions".

Since a transaction can include multiple exits, the number of total exits is more significant than the number of transactions, according to the website. "The big players in the Bitcoin space use batching – the process of including multiple outputs in a given transaction – to reduce their total transaction fees, so looking only at the transactions is missing an important part of the image."

For all of 2018, the average exits to the transaction ratio have decreased

The website tracks data from January 2018, which is a limitation, but we can see & # 39; Average outputs per block & # 39; in 2018 approximately following & # 39; Average transactions per block & # 39;

On January 4, 2018 we saw that the average output per block reaches a maximum of 7,420. The peak for Transactions Per Block arrived much earlier when there were 4322 transactions per block on January 4th.

Throughout 2018, the ratio between the average exits and the ratio of transactions has decreased, perhaps indicative of the decline in overall economic activity on the bitcoin blockchain, due to price consolidation.
