## Transaction size calculator

How much power does it take to mine a bitcoin? In this assessment we find that an average of , kWh of energy is required to produce one bitcoin. Our method to discover the amount of energy it takes to mine a bitcoin uses data from relevant ASIC models, network size, and current miner profitability. We also calculate the bitcoin production rate and use it to find how much energy the entire network consumes. But this estimate is always changing alongside hash rate size and other factors.

Further, find out why we believe hash rate growth may be slowing and is not linear. This model houses a couple hundred TSMC 7nm microprocessor chips. It consumes watts W power per hour with an efficiency of But, one machine alone takes about 3 years to produce one bitcoin. Thus to discover how much power it takes to mine a bitcoin, we need to consider how much energy the entire network uses rather than just one unit.

So to find out how much energy these 1, ASICs require, we multiply the amount of machines by their kilowatt kW specification over one day of mining.

Hence, it requires 86, kWh to produce one bitcoin with S19 Pros. This is the same as Read more about electricity unit conversions here. Accordingly, the actual power demand to produce one bitcoin is slightly higher than this first prediction.

See below. This provides the estimated kWh per BTC for each miner type. We find that with an average network efficiency of This is equivalent to MWh, or 0. Next we will see how much energy the network uses per day. So this means that in April the network used over a third more electricity to create a bitcoin as it did in August of Furthermore, it is difficult to know exactly how many of each ASIC model is currently running, or the accurate market share of manufacturers.

So these are assumptions. But thanks to improvements in the energy profiles of bitcoin miners alongside microprocessor chip advancements , hardware uses less energy per terahash to produce bitcoin over time. Yet manufacturing bottlenecks limit the release of new machines, keeping older generation hardware on the network. If we want to work out how much energy the entire Bitcoin network consumes each day, we need to do some groundwork.

First we must find out the current rate of bitcoin production. Bitcoin nodes receive and organize pending transactions from bitcoin users in the mempool. Transactions awaiting confirmation in the mempool are sorted by priority based on the highest-to-lowest fee set per transaction.

So, transactions with very little fees may sit idle in the mempool for some time, whereas transactions with high fees are verified quickly. When proof-of-work PoW miners find a block, a number of transactions are added into that block. The amount of transactions in each block is controlled by the maximum byte-size of the block.

When the block is filled with pending transactions, PoW miners verify and timestamp that block. Once the block is stamped it is added onto the blockchain and appears in the public ledger. For example, most vendors and exchanges only accept a BTC payment once 6 confirmations have been completed, aka six additional blocks following a verified transaction are added to the blockchain.

Therefore, the more confirmations, the more secure a transaction is. The block pace is the rate which PoW miners discover new blocks through a hashing puzzle.

The amount of time it takes PoW miners to find a block adjusts automatically over time by the difficulty level. The target rate of block discovery is every 10 minutes. Thus, the average block pace is one block per 10 minutes. This is equivalent to 6 blocks per hour, or blocks a day. When miners find a block they are gifted a block reward which is also the issuance of new bitcoin.

The block reward is currently 6. So, the rate of coin issuance is 6. Although, keep in mind that the block reward diminishes over time. In the year the block reward will shrink from 6.

Halvings occur every four years, read more about miner trends here. Using the variables described above, we find that the rate of bitcoin production is This means around bitcoin are produced per day, and , are created per year. See our calculations below. This occurs every blocks, or about every 2 weeks. This mechanism keeps the system working like clockwork without mediation. It also incentivizes miners to use the most energy efficient machines to keep ahead of their competition.

As hash rate grows, bitcoin mining difficulty becomes harder. However, sudden drops in hash rate between difficulty epochs can cause the block pace to lag, resulting in a temporary decrease in coin production.

Likewise, when the hash rate grows between difficulty epochs because more miners join the network, the block pace may temporarily speed up. Then more bitcoin are produced per hour. Regardless, the block pace always averages itself to 6 per hour without fail.

Next we find out how much power the network uses daily. To do this we take the product of the average amount of kWh it takes to mine a bitcoin, and the rate of bitcoin production. From our previous calculations we know that at an average efficiency of This is equivalent to MWh or 0. To get the daily amount of energy the network uses, we take the kWh to mine one bitcoin times the daily production rate of coins.

To put this into perspective a typical nuclear power plant produces MW electricity. This equals 24, MWh per day, or 24 GWh. Whereas a large-scale energy provider like the Three Gorges Dam in China spits out a maximum capacity of This amounts to , MWh per day, or GWh. So, in theory, a typical power plant could mint up to bitcoin per a day, and Three Gorges Dam could create four times the maximum of bitcoin per day.

See how we did this below. Today the world has around 62, power plants. Furthermore, the world produces over TWh of energy per day, or , GWh. Thus, Bitcoin uses 0. We also know that much of the energy bitcoin miners use is stranded, or otherwise wasted energy. So in the big scheme of things, how much power it takes to mine a bitcoin is negligible.

Why is Bitcoin scapegoated for its energy consumption? Perhaps because financial institutions and world leaders fear losing their Cantillon privileges. Eventually money trickles downs to the populace, but working people pay a higher price. This creates inflation and an uneven distribution of purchasing power. Today things are more extreme than what Cantillon observed.

Rich rent-seekers live off of the interest paid by lower lying citizens on the money-chain, without bringing any real benefit to society. Bitcoin fixes this by limiting the coin supply to 21 million, and not favoring a certain social class.

But, Bitcoin miners have access to the newly printed money? Yes, but this money is not all profit, miners must use their earnings to stay competitive. This is because the distribution of coins is in the form of miner rewards which is based on game theory.

Game theory does not care about your social-class privileges. Additionally, Bitcoin allows a greater amount of privacy than current financial institutions. Whereas Big Brother must always know what the inferior populace is doing in order to control them. In conclusion, the amount of energy it takes to mine a bitcoin is estimated to be between 86, — , kWh. But remember that variables like hash rate, BTC price, and miner earnings are dynamic which affect results.

No, network growth has a limited capacity. However, due to negative feedbacks and exogenous limitations this is not the case. Bitcoin trends are nonlinear because it is a complex system. In fact, despite continuing BTC price increases miner profitability diminishes over time thanks to negative feedbacks.

See in green below. Also, the amount of energy available to bitcoin miners is scare. This caps network growth. By definition, the carrying capacity in a biological species model is the total amount of habitat resources like food and shelter available to sustain a limited population size. Similarly, bitcoin miners require electricity to sustain their population size.

Further, despite microchip advances which lower ASIC efficiency profiles and increase profit margins, the overall cost and energy required to mine a bitcoin will rise over time.

## How Bitcoin mining really works

Every blocks, or about every two weeks, bitcoin resets how tough it is for miners to mine. Early Friday morning, as expected, the bitcoin code automatically made it about 7. Historically speaking, this spike in difficulty is on the larger side, but it isn't surprising, nor is it alarming. But it marks the first sizable increase since the Chinese mining ban took effect and serves as confirmation of a trend we already knew was underway: Some of the miners that used to be in China are finding new homes elsewhere.

We've all heard the stories of Bitcoin millionaires. But it isn't just the digital asset's price that has hit an all-time high.

There's also live online events, interactive content, certification prep materials, and more. Mining is the process by which new bitcoin is added to the money supply. Mining also serves to secure the bitcoin system against fraudulent transactions or transactions spending the same amount of bitcoin more than once, known as a double-spend. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded bitcoin. Miners validate new transactions and record them on the global ledger. Miners receive two types of rewards for mining: new coins created with each new block, and transaction fees from all the transactions included in the block.

Transaction fees are included with your bitcoin transaction in order to have your transaction processed by a miner and confirmed by the Bitcoin network. The space available for transactions in a block is currently artificially limited to 1 MB in the Bitcoin network. This means that to get your transaction processed quickly you will have to outbid other users. The fees shown at the historic charts and tables are in US dollars per transaction and in satoshis per byte. To calculate the fees per transaction, we consider that the average Bitcoin transaction is about bytes big. Whenever a transaction is sent, miners demand for an arbitrary amount of bitcoin fractions denominated in satoshis, the hundred millionth part of 1 BTC so that they add that specific transaction in the next block.

This price is recommended for users who want their transaction to confirm in less than 5 minutes and is a good indicator of the fair gas price at the time. The heatmap calculates an average of these standard prices for each 1 hour window using data from the previous two weeks. Gas is used to pay for transactions on the Ethereum blockchain. The amount of gas required for each transaction depends on the complexity of the transaction.

Weight units are a measurement used to compare the size of different Bitcoin transactions to each other in proportion to the consensus -enforced maximum block size limit. Weight units are also used to measure the size of other block chain data, such as block headers. As of Bitcoin Core 0. Virtual size vsize , also called virtual bytes vbytes , are an alternative measurement, with one vbyte being equal to four weight units. That means the maximum block size measured in vsize is 1 million vbytes.

A few years ago a heated debate resulted in the first war on the Bitcoin network. The disagreement was about how large blocks of the blockchain should be, how easy it should be to change Bitcoin's rules, and ultimately it was about control.

All sizes in parenthesis in the overhead , input , and output sections are vbytes. Sizes in the common elements section are bytes. Input count compactSize The number of inputs included in the transaction. Output count compactSize The number of outputs included in the transaction. Maximum of 3 vbytes for a maximum-length scriptSig 10, vbytes. This data is used to prove that the transaction is authorized by someone controlling the appropriate private keys.

The chart shows a mempool snapshot from my node. The mempool contains unconfirmed transactions waiting to be included in a block. Each transaction pays a fee and has a size. Transactions paying a higher fee per size feerate are usually included earlier than low feerate transactions.
