And, hash rate is an estimate based on the block pace and difficulty target. As a result hash rate estimates also vary. So, which hash rate reading is the correct one?

We then show why it is important to understand how sample time windows, distributed systems, and miner luck could create hash rate bias. We also look closer at block pace and its behavior.

And, because the difficulty calculation is deterministic everyone can calculate the target independently. This means that all bitcoiners come to the same difficulty target without relying on a centralized authority.

The purpose of difficulty is to keep the rate of coin issuance and block confirmation intervals steady over time. The difficulty target also enforces protocol rules. For example, miners need to have consensus on the current difficulty, in order to achieve the correct nonce so that they can hash a viable proof-of-work solution.

Likewise, a full node will reject a block submitted by miners that does not have a double SHA hash value less than the difficulty target. Although, there are various ways to measure difficulty. Here is the most basic formula:. In the equation above the Difficulty Target hexadecimal is the highest possible target to be reached with a block hash, with a difficulty of 1.

The Current Target is the hexadecimal difficulty derived from the bit number in a block header. So, when the two hexadecimal numbers are divided, it results in the Difficulty Level which is a whole number. And, as previously mentioned, the difficulty level is the approximate amount of hashes miners need to perform to find a block.

Each block interval is known as a difficulty epoch. At the beginning of every epoch the Bitcoin network recalculates the Current Target. The network does this by summing the total minutes it took to mine the last 2, blocks.

It then compares this total to a desired rate of 20, minutes 10 minutes times 2, blocks. This ratio is multiplied by the current difficulty level, resulting in a percent change up or down.

The protocol limits the lowest possible difficulty level to 1, yet the is no upper limit. Interestingly only blocks are actually included in the difficulty calculation. The interval between blocks is left out. This protocol bug may speed up coin issuance by about two years in total, but fixing it would require a hard fork. Additionally, blocks backwards is The smallest adjustment was Generally the block pace follows a Poisson distribution, where the majority of blocks are found within a 10 minute window.

See the histogram below. However, as with any random process, block intervals are sometimes very small or very large. For example, see below how the daily block pace in blue varied much more than the 2,block average in green the past year. Notice above that when the block pace in green exceeds the target of 10 minutes, the difficulty in blue drops thereafter to make it easier to mine a block.

On the other hand, when the block pace is too fast and below the red line, the difficulty in blue goes up in the next epoch.

Difficulty and block pace are directly affected by the amount of miners online. If more miners join the network during an epoch, then block pace speeds up.

Vice versa, if many miners leave the network, then block pace may slow until the difficulty readjusts. Read more about miner trends here. The difficulty is derived from the block pace, and the hash rate is estimated from the difficulty. We then explain why ASIC miner running patterns, time windows, behaviors of distributed systems, and miner luck can create hash rate estimate variance. Each guess a miner makes toward solving for the next block is called a hash.

However, when we talk about machines, mining pools, and the network size, we use different SI-Prefixes which can be confusing. Pretty crazy, right? Additionally, we can use the network hash rate to estimate the number of machines currently online.

We find that there are about 2. S ee the steps below. One way is by making a Bitcoin Core node query. Try this command :. This json object reads: the current block height; the difficulty level; the network hashes per second in scientific notation; the amount of transactions waiting for confirmation in the mempool; the network name; and any warnings on the network or blockchain.

Only hash rate measurements collected over longer periods of time are indicative of change. This same principle holds true for ASIC miners. So, like the hash rate returned by the node command, an ASIC hash rate reading is only accurate when averaged over longer periods of time. Or, MW, which is the size of an entire nuclear power plant. Unless of course a huge event like a natural disaster or policy change occurs in a location that is highly concentrated with miners. Because each websites uses their own simplified metrics and data from arbitrary time windows.

And, shorter time windows create more variance. In particular we will discuss why time windows affect the network size. Hash rate is an estimate because Bitcoin is permisonless and miners do not need to identify themselves. And it is this data that is used to estimate the hash rate. This hash work is then multiplied by the current difficulty, over the second 10 minute target block pace. But this equation is very general. It does not compare the actual block pace to the expected block pace.

Thus, to find a better estimate of the current hash rate, we take the actual rate of finding a block versus the expected rate of finding a block. We then multiply this ratio by the difficulty and hash work to find a block, over the ten minute target.

See below:. In 12 hours we would expect 72 blocks to be found at a rate of one every ten minutes, but only 65 are found. And, the current difficulty is 24,,,, Moving average hash rate measurements can be based on data from the previous hours, hours, 3-days, 7-days, or days. But, as previously discussed, the shorter the time window, the more variance is present.

To show how time windows matter, we compare the hour hash rate to the 7-day average over the past year below. Why is there such a large discrepancy? So a small variance can create a large discrepancy. See an illustration of this concept below. So far we have discussed external reasons why hash rate readings differ, including miners coming and going from the network, oscillating hash rates from ASICs, as well as the fact that hash rate readings use arbitrary time windows.

But, because Bitcoin is a distributed system, irregularities exist from within which can also affect hash rate estimates. For instance, not all nodes are directly connected to one another which creates lag. Blocks may be timestamped inconsistently. Furthermore, the block pace may speed up or slow down temporarily due to miner luck. Bitcoin is a distributed ledger on a dynamic peer-to-peer network. This means that updates of the blockchain performed by each node are not the exact same as all other nodes at any one time.

However, over time the blockchain guarantees consistency. For example, transactions are only confirmed once two or more subsequent blocks have been found. Also, one hundred blocks must be mined before a miner can spend their rewards. This means that hash rate estimates which use small time windows, like 12h, may be bias due to a minor lag in nodes updating their blockchain.

Additionally, block timestamps can sometimes be out of order. Thus it becomes possible for a block to have a lower timestamp than its predecessor.

Although rare, this phenomenon may create variance in shorter block time analyses and hash rate estimates.

More specifically, the consensus rules state that timestamps must be greater than the median of the past 11 blocks, and less than the network-adjusted time plus 2 hours. The network-adjusted time is the median of timestamps returned only by the nodes directly connected to the one measuring at that instance. To imagine this subnetwork, look at the green lines in the Distributed Decentralization image above. Lastly, it is important to understand how luck affects hash rate readings.

Usually block times follow a Poisson Distribution where the majority of blocks are found around the 10 minute mark. However, sometimes many blocks are found in quick succession due to a period of high luck. Other times no blocks are found for a period due to bad luck. Although, mining pools define luck a little differently. If a pool finds more shares than they predicted given the amount of hash rate they have online, they are experiencing high luck.

Periods of high luck may speed up the block pace temporarily, resulting in hash rate estimates becoming higher than they truly are. Here is an example of this phenomenon from earlier this month:. And as previously mentioned, the hash rate cannot really change this much in one day unless a huge event occurs.

By this stage, you will understand how bitcoin works, and what mining means. But we need to get from theory to practice. How can you set up bitcoin mining hardware and start generating some digital cash? There are two main things to think about when choosing it:.

How Many Hashes Create One Bitcoin?

The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since This is consistent with the perspective that, in order to keep the Blockchain system secure from double spending attacks, the proof or work must cost a sizable fraction of the value that can be transferred through the network. Bitcoin is a digital currency launched in by an anonymous inventor or group of inventors under the alias of Satoshi Nakamoto Nakamoto, It is the largest cryptocurrency in market capitalization with over billion dollars Chan et al. As a decentralized currency, Bitcoin differs from government regulated fiat currencies in that there exists no central authority within the network to verify transactions and prevent frauds and attacks Sin and Wang, Instead, Bitcoin relies on a highly replicated public ledger, secured by means of a hash chain and validated through community consensus Akcora et al.
