What Is Hashrate In Blockchain

Is The Price Of Bitcoin Correlated With The Hashrate

Blockchain Hashing Explained | Proof-of-Work & Hashrate

The correlation of Bitcoins hashrate and the cryptocurrencysprice has been a hot topic in the digital asset space for some time now.

Correlation 101:

If Bitcoins price and hashrate correlate at 1, it means that they always move in the same direction.

The higher the rate, the more the two variables are related to each other and vice versa .

There can also be a negative correlation between the two variables. A correlation of -1 would mean that theres a great relationship between the Bitcoin price and hashrate, but they move in the opposite direction.

Cointelegraphs data, suggests that there is indeed a high correlation between Bitcoins hashrate and price, with the rate being at 86.2% in 2016 and 91.5% in 2017.

While the digital assets price and network hashrate were movingin the same direction in 2016 and 2017, the correlation turned negative during 2018s bear market.

However, as soon as the crypto winter was over in2019, the correlation between BTCs hashrate and price turned positive again,with a yearly rate of 59.5%

The data indicates that, normally, theres a high positivecorrelation between the Bitcoin price and the network hashrate. However, along-lasting bear market could quickly turn this correlation negative.

Is Bitcoin Mining Legal

The legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places.

Bitcoin ownership and mining are legal in more countries than not. Some examples of places where it was illegal according to a 2018 report were Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan. Overall, Bitcoin use and mining remain legal across much of the globe.

So What Does A Merkle Tree Have To Do With Blockchains

Each block contains thousands and thousands of transactions. It will be very time inefficient to store all the data inside each block as a series. Doing so will make finding any particular transaction extremely cumbersome and time-consuming. If you use a Merkle tree, however, you will greatly cut down the time required to find out whether a particular transaction belongs in that block or not.

Lets see this in an example. Consider the following Merkle tree:

Now suppose I want to find out whether this particular data belongs in the block or not:

Instead of going through the cumbersome process of looking at each individual hash and seeing whether it belongs to the data or not, I can simply track it down by following the trail of hashes leading up to the data:

Doing this significantly reduces the time taken.

Hashing in mining: The crypto puzzles.

When we say mining, it basically means searching for a new block to be added in the blockchain. Miners from around the world are constantly working to make sure that the chain keeps on growing. Earlier it used to be easy for people to mine using just their laptops, but over time, people started forming mining pools to pool in their computer powers and mine more efficiently.

What Are The Cryptographic Hash Functions

Cryptographic hash functions are characterized by several properties making them very useful when employed in the cryptographic sphere.

  • The result of a hash function is always identical. This characteristic is called deterministic. Regardless of how many times you enter the same message, the output will be the same after the hash function is applied. However, the slightest change in the input data changes the result completely.
  • It features fast computation as low speed would make the system inefficient.
  • Preimage resistance feature in hash functions makes it computationally infeasible to determine the input from the hash value. Therefore, miners can only compare the result until a match is found.
  • What Is Hash Power/hash Rate

    Hash Rate

    The hash rate of a mining rig is the number of hashes that it can calculate per second. The combined hash power of a cryptocurrency network is the sum of the hash rates of all mining rigs that are in operation at any given moment.

    On the other hand, the overall hash rate of a cryptocurrency network is an indicator of that coins security: in order to hack the network for personal gain, the attackers need to overcome its total hash power making the task nearly impossible at high enough hash rates.

    Bitcoin Network Hash Rate

    The hash/s is also used in calculations of the Bitcoin network’s overall hash rate. Because each miner or mining pool only relays a solved block to the network, the overall hash rate of the network is calculated based on the time between blocks. While not an accurate measure of network hash rate at any given instance in time, measurements over longer periods can be considered indicative and similar calculations are used in Bitcoin’s difficulty adjustment.

    In January 2015, the network hash rate was around 300 Phash/s, or 300 quadrillion hashes per second.

    If you compare a bitcoin mining device to one that is designed to mine, for example, Ethereum, you will notice a very large apparent difference in hash rates. This is because there are many different algorithms that cryptocurrencies use. They all require different amounts of memory and computing power in order to be mined. To put it simply, bitcoin and its SHA256 algorithm is considered by today standards to be relatively easy to compute. As a result, a mining device that is still relevant today would need to produce hashes in the terahash range and up.

    If we were to compare this to Ethereum, youll find that most modern Ethereum mining devices operate in the megahash range.

    Blocks And The Blockchain

    Bitcoin and many other cryptocurrencies are built using blockchain technology. Blocks are similar to files which hold data about the most recent transactions made throughout the networkand in a blockchain, they make a chain, each one dependent on the others.

    The Bitcoin network is designed to make sure that a consistent number of Bitcoins are released into the market over time.

    Every time someone purchases Bitcoin or uses it as payment, the transaction is recorded on the blockchain. All transactions can be viewed publicly , and they cannot be changed. The Bitcoin blockchain is a decentralized, digital ledger containing a record of all past transactions. The network confirms those transactions, and since the network is decentralized, the ledgers record is secure.

    But since blocks are like data files, larger blocks require more power to verify. Thats where hashing enters the picture. Hashing a block is the process of ensuring the validity of the network transactions. As a reward for hashing, miners receive bitcoins.

    To successfully mine a block and receive bitcoins, a machine has to hash the blocks header, which is a summary of the information contained within a given block .

    Its a complex process, but the important thing to know is that the Bitcoin network is designed to make sure that a consistent number of Bitcoins are released into the market over time. To keep this consistent, bitcoin mining becomes more difficult over time.

    What You Need To Mine Bitcoins

    Although early on in Bitcoin’s history individuals may have been able to compete for blocks with a regular at-home personal computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time.

    In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they’ll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2,016 blocks, or roughly every two weeks.

    When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. At today’s network size, a personal computer mining for bitcoin will almost certainly find nothing.

    All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU or, more realistically, an application-specific integrated circuit . These can run from $500 to the tens of thousands. Some minersparticularly Ethereum minersbuy individual graphics cards as a low-cost way to cobble together mining operations.

    How Hash Rate Can Affect Investors

    What Does Hashrate Mean? | Hashrate Mining Explained

    A high hash rate indicates a healthy network, which may, in turn, lead to higher Bitcoin values.

    Currently, hash rates are significantly higher than in years past, and should continue to increase. That may mean that Bitcoin values followthough given the volatility of cryptocurrency, there is no guarantee. Plus, simple supply and demand could become the dominating factor determining Bitcoins price going forward.

    Past trends are not predictions for the future, and you should do your research and consider your risk tolerance before making any moves.

    Bitcoin Vs Ethereum Energy Consumption

    Bitcoin remains the most energy exhaustion cryptocurrency. When comparing Ethereum and Bitcoin, Ethereums consensus aims to reduce 99% of its energy consumption. In comparison, Bitcoins PoW continues to surge, where it already exceeds the total energy consumed in the whole of Switzerland. With the migration to , the network is supported by validators instead of miners. Hence, its more sustainable and leaves a lesser carbon footprint on the environment.

    What Is The Motive Behind This Drop

    The report explains that because the BTC hashrate achieved its ATH, miners began producing blocks at such a speedy price that the community made an upwards issue adjustment on the subsequent day .

    As greater mining issue results in lesser profitability, a number of the miners who had excessive electrical energy prices determined to shutdown their operations.

    This result in the 8% decline within the hashrate. Now, as a consequence of this drop, the block manufacturing price has additionally naturally dropped. Nevertheless, the block manufacturing price is definitely decrease in the mean time than whats required on the Bitcoin chain.

    The report notes that due to this, the issue is now anticipated to lower once more subsequent Saturday, paving approach for the hashrate to develop as soon as once more.

    On the time of writing, BTCs price floats round $48.8k, up 2% within the final seven days. The under chart reveals the development within the value of BTC over the past 5 days.

    The PoW concept was designed to counter DDoS attacks that would freeze the system and refuse to process user requests. PoW also resists spam and effectively protects the entire network. Though this is not an ideal solution to the problem, this concept is still relatively efficient.

    In the crypto world, PoW protects cryptocurrencies as it supports decentralized networks. A simple example: the person creates a digital wallet that is not synchronized with the rest of the network. As soon as he gets connected, the wallet changes its status to synchronized as it starts accessing the blockchain.

    Hash Rate Measurement And Units

    Bitcoin hashrate hits new high, but market dominance falls

    To compute a hash rate, the unit hashes per second is used. This is used to gauge the speed of the machine used for bitcoin mining. It is counted using terms like Kilo, Mega, Giga, Tera, Peta, and Exa.

    For example:

    • 1 kilo hash per second = one thousand hashes per second
    • 1 mega hash per second = one million hashes per second
    • 1 giga hash per second = one billion hashes per second
    • 1 tera hash per second = one trillion hashes per second
    • 1 peta hash per second = one quadrillion hashes per second
    • 1 exa hash per second = one quintillion hashes per second

    Another notable fact is that hash rates vary depending on the cryptocurrency and what machine or equipment was used to mine it. Different cryptocurrencies donĂ¢t have the same amount of hash power.

    As mentioned, hash rate is measured in hashes per second, or H/s for short. At the time of writing , the hash rate is sitting around 74 EH/s But wait, whats an EH/s? I hear you scream.

    As the Bitcoin network grows and can compute more hashes per second, its hash rate increases. The addition of more powerful, application-specific integrated circuit mining machines also increases the networks hash rate.

    Over Bitcoins 10-year life, the network has grown so powerful that it can compute quintillions of hashes every single second. For easy comprehension, 74 quintillion hashes per second is written as 74 EH/s.

    Its also common for hash rates of blockchain networks to be written in kH/s , MH/s , GH/s , TH/s , PH/s , and ZH/s .

    Thing is, just because the Bitcoin network is getting more powerful doesnt mean it verifies or mines blocks any quicker.

    Bitcoin is programmed by design to mine a block about every 10 minutes, on average. It maintains this rate of production by adjusting the mining difficulty in line with the overall hash rate of the network.

    In short, it makes it more difficult for miners to complete the hash puzzle. Generally speaking, as hash rate increase, so does Bitcoins mining difficulty, but thats a topic for another day.

    Effects On Energy Consumption And Profitability

    Since the hash power also relies on the performance of the computers used in mining, a lot of miners are investing in powerful equipment to have more chances of having higher hash rates. These computers are expensive and also consume high levels of electricity to run its operations.

    Before, miners can acquire cryptocurrencies using ordinary computers and graphic cards. However, with the rising popularity of bitcoin and other digital currencies, a lot of miners have joined the competition with new and more powerful mining hardware like the application-specific integrated circuit miners.

    These factors caused the bitcoin hash rate to immediately increase and eventually paved the way for the difficulty level of mining to also rise. This, in turn, enables miners to generate more income. However, as the mining difficulty increases, more energy is consumed by computers. Thus, the percentage of electricity consumption also increases.

    What Is The Impact Of The Hashrate On Bitcoinmining

    Bitcoin uses the PoW algorithm for reaching consensus, which requires miners to compete with each other to generate new blocks and earn block rewards for their efforts.

    Block generation takes approximately 10 minutes on the BTCnetwork.

    To maintain the 10-minute block generation time, the Bitcoinnetwork is utilizing a self-regulating mechanism to adjust the miningdifficulty every 2,016 blocks, which comes down to about two weeks.

    If the total hashrate increases in the ecosystem, the Bitcoinnetwork will raise the difficulty of finding a new block for miners to keep thetime to generate a block at 10 minutes.

    Therefore, we can safely say that the total hashrate of thenetwork has a great influence on Bitcoin mining difficulty.

    What Do You Mean ‘the Right Answer To A Numeric Problem’


    The good news: No advanced math or computation is really involved. You may have heard that miners are solving difficult mathematical problemsthat’s true but not because the math itself is hard. What they’re actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number that is less than or equal to the target hash. It’s basically guesswork.

    The bad news: It’s a matter of guesswork or randomness, but with the total number of possible guesses for each of these problems being on the order of trillions, it’s incredibly arduous work. And the number of possible solutions only increases the more miners that join the mining network . In order to solve a problem first, miners need a lot of computing power. To mine successfully, you need to have a high “hash rate,” which is measured in terms gigahashes per second and terahashes per second .

    As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many exchanges. Alternately, you can always leverage the “pickaxe strategy.” This is based on the old saw that during the 1849 California gold rush, the smart investment was not to pan for gold, but rather to make the pickaxes used for mining.

    To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. You may consider looking into companies that make ASICs equipment or GPUs instead, for example.
