Bitcoin is the first successful implementation of a distributed crypto-currency, described in part in by Wei Daion the cypherpunks mailing list. The bitcoin scalability problem is the limited rate at which the bitcoin network can process transactions. It is related to the fact that records (known as blocks) in the bitcoin blockchain are limited in size and frequency.. Bitcoin's blocks contain the transactions on the bitcoin network.: ch. 2 The on-chain transaction processing capacity of the bitcoin network is limited by the average. Bitcoin (símbolo: ₿; abrev ISO BTC ou XBT) é uma criptomoeda descentralizada ou um dinheiro eletrônico para transações ponto-a-ponto (peer-to-peer electronic cash system) apresentada em ,  na lista de discussão The Cryptography Mailing  por um programador ou grupo de programadores sob o pseudônimo Satoshi Nakamoto,    é considerada a primeira moeda.

The first online purchase using bitcoin was performed by Laszlo Hanyecz in The real name of the Bitcoin developer remains unrevealed to this day. No more than 21 million Bitcoins will ever be created. There are currently more than cryptocurrencies. Interesting new articles. Mining farm — is a data center , technically equipped to mine bitcoins or other cryptocurrencies.
They were emerged as a result of the constant complication of the process, which requires more technical, energy and financial resources. Farms allow the productivity of computers and, consequently, the Hash Rate to be maximized.
Physically, farms are rooms with a large number of computers and servers that take on tasks for mining. There are also home-mining farms.
They differ from ordinary PCs, by being specially assempled and designed for mining. Home farms can bring profitability, but users often face the problem of excessive electricity consumption and overheating of the computer at home which makes mining unprofitable. One of the main resources into which a miner has to invest is electricity. In addition, a large number of processors require an appropriate cooling and ventilation system. Cloud mining is a process of obtaining Bitcoins with the use of a remote data processing center with the general computational power.
This allows the users to mine Bitcoins or alternative crypto currencies without controlling the equipment directly. Another option is a private virtual service, where a user installs the mining software.
Finally, a user may take the computational powers themselves by using already the results of their work and not coming in touch with physical or virtual servers. Web-mining, or "hidden mining" — is an alternative method of cryptocurrency mining through the web browsers of users of websites. In fact, owners of Internet resources can convert the capacities of visitors' computers into cryptocurrency.
There are also viruses that make computer capacities work for cryptocurrency mining. Profitability of mining is the level of reward that a user of the blockchain network receives providing of his technical capacities for verifying transactions and solution of network tasks, resulting in a new data block on the network. The profitability depends on two related factors.
The first one consists in the complexity of the process itself, on which the reward depends the more difficult the process is, the smaller amounts of tasks can be made per technical resource unit and, consequently, the less reward you will receive. The second factor is the cost of bitcoin or other crypto currency. That is, how much your reward is in terms of fiat currencies. However, this indicator does not take into account additional investments: rental of premises, management of farms and energy costs.
Specifically for Bitcoin, the number of mining types has significantly decreased. If other cryptocurrencies can still be mined using video cards, processors, hard drives, etc.
A central processing unit or CPU is an integrated circuit that is an essential part of the hardware of a personal computer or any other equipment. Currently, any modern, high-performance computer is equipped with a powerful central processor with a high frequency of operation and several cores. Accordingly, if a miner has a good personal computer, then he will not have to invest hundreds or thousands of dollars in equipment.
