A hacker installs bitcoin mining malware on hundreds of computers to distribute the work between them. Bitcoin’s mining calculators have calculated the electrical consumption of these operations and are sufficient to increase electricity bills, burn the CPUs and make computers fail completely. Bitcoin mining itself is not harmful and involves using a computer to solve difficult mathematical equations so that the user can win bitcoin. The user gains bitcoin by checking the transactions in blockchain, a digital accounting book, similar to a bank book, that tracks all transactions of a particular cryptocurrency.
In fact, it is necessary to validate transactions and obtain community consensus to ensure the attack system. First, extracting Bitcoin does not mean obtaining some kind of monetary value. The network encourages users to participate in the block validation process by assigning newly extracted Bitcoins to the first user to randomly find a hash with a value below the threshold. Currently, after the last halving of Bitcoin, this fee is 6.25 Bitcoins or approximately $ 60,000 at the current exchange rate . For this reason, the hash process is called “mining” and miners often come together to form large mining groups to have a more stable source of income (Gervais et al. 2014).
We must not forget that this formula is an upper limit for the cost of the work test. It greatly underestimates the cost of an attack and significantly overestimates the attacker’s earnings. In fact, consider a system that has no other protections or security systems than the function test. In addition, it does not believe that after a successful attack, Bitcoin’s value is likely to decline, making it unlikely that the attacker will spend his profit at its current market value. Finally, we must take into account that the attacker must control more than 50% of the hash power.
By looking at all the costs and power that these networks enter, it is difficult to remain optimistic about their long-term potential. At some point, all of this is hitting a plateau and in the absence of zero point energy or a future technology that allows clean energy far above what we are currently using, chances are mining viability will eventually stop. It may not be this year or next year, but the growth in hash rates, energy consumption and prices cannot, of course, increase indefinitely, and it will not. Cryptomone networks are designed to find a ‘stable’ balance, which basically means that enough people have to create and use the currency to make it viable. Because bitcoin transactions require so much computing power to verify, the hardware for bitcoin mining must be constantly cooled by special fans.
Since distributed accounting has no centralized authority, the mining process is crucial to validate transactions. Therefore, miners are encouraged to secure the network by participating in the transaction validation process that increases their chances of earning crypto mining hash rates freshly minted coins. Bitcoin mining is the process of creating new bitcoins, a process with a limit of 21 million BTC, according to the Bitcoin protocol. As time passes, Bitcoin mining becomes more difficult as more miners compete for the next block reward.
