Bitcoin Networks
Peer-to-peer networks that are operated through cryptographic protocols.
Mining: 
Bitcoin uses a "proof of work network" to create a distributed timestamp server as a peer-to-peer network. This work is often called Bitcoin Mining. The signature is not available, but the signature is found out. This process is intensely related to energy. More than 90 percent of total expenditure is spent on electricity for miner management. In order to operate an information center for Bitcoin Mining in China, it requires a maximum of 135 megawatts of power.
The original invention of Satoshi Naakamoto was the need to prove proof of work to provide signature for Blockchain. There is a block in the mining process, which provides a smaller number than the target of the given difficulty when having hash twice with the SHA-256. Where the required average amount of work increases in the opposite proportion of the target of the target, then a hash can be verified by launching a round dual SHA-2556.
Bitcoin can be found to be valid for a timestamp network by increasing one of the number of times it can be used. As long as the hash number of the block has not been given the required number of precursors, then the value of the number is increased. Once the hash process returns a valid result, the block can not be changed until the task is re-executed. After the blocks are chained with it, the next one is to work again to change the blocks.
Most consensus is expressed in Bitakay with the largest chain, and the maximum effort is required to create this chain. If the majority of the power measurements are controlled by the proper node, then the number of honest chains will also increase rapidly and it will surpass any competitive chain. To change any of the previous blocks, an attacker must reproduce the block and all the subsequent blocks of work, and have to print the work of a good node. As soon as the block is added, the likelihood of being able to keep pace with an aggressive attacker decreases exponentially.
Disadvantages: 
Bitcoin Mining is a competitive endeavor. One kind of "best weapon-winning competition" was seen through various hashing technologies used in the Bitcoin mines. In many gaming computers, FPGA and ASIC, common CPUs, the use of higher GPUs reduces the profitability of the little specialized technologies. Specialized ASIC for Bitcoin has now become a basic way for bitcoin mining and the drop in GPU has exceeded 300x. Since bit queues have become more difficult, computer hardware manufacturers are seeing increased sales of high speed ASIC products.
To reduce the difference between income from miner, the power of the computer is often gathered or submitted ("pooled"). Each mining rig has to wait a long time to ensure transactions and payments made. When the participating server can solve a block every time, all miners participating in a pool pay the money. This money is given based on the amount of work done by each miner to find that block. Bitcoin data centers generally spread out of the public eye and spread around the world, and there is also the tendency of being surrounded by centers around low-cost electricity areas.
Power Consumption:
In 2013, Mark Gimin calculated that the cost of electricity could be 40.9 megawatts (982 megawatt-hours a day). In 2014, according to Hac McCack, 80.7 megawatt (80,666 kilowatt) of this expenditure In 2015, according to the Economist, if all miners use modern facilities, the combined electricity costs can be 166.7 megawatts (1.46 terawatt-hours per year).
To reduce costs, Bitcoin mines have been installed in places like Iceland where geothermal energy is cheap and free of cold polar air free. Chinese Bitcoin Miners use Tibet's hydroelectric power to reduce electricity costs.
The overall description of the process of miting the bitcoin:
New transactions are broadcast on all nodes.
Each miner's node collects new transactions in a single block.
Each miner node works to find a job proof code for its block.
When a node finds the proof of a work, it blocks the transmission of all the nodes.
Accepting documents validates all transactions and only if all transactions are valid.
Includes the hashed block of approved blocks and the nodes start accepting themselves after starting the next block.
Mines made Bitcoin: 
According to the convention, the first transaction of the block is of a special kind, which produces new bittacquains owned by the owner of the block. It is considered as an incentive for nodes to support the network. It also shows the way to execute new bitscannies. After every 210 million blocks, the amount of mining reward is half. It started its journey from 50 Bitcoin, in late 2012, it decreased to 25 and reached 12.5 bitcount in 2016. This half-way process continues to run 64 times until the completion of the new Bitcoin.
