Where Bitcoins generate from?
While coins are minted, paper money are printed, digital money are mined.
The rules of how Bitcoin mining works are defined by the Bitcoin protocol and implemented in its software. Bitcoin cryptocurrency uses POW (proof-of-work) algorithm to create supply of bitcoins and verify transactions. Also it is claimed to be the one of possible defenses against DoS attack. To prevent it the network demands from miners to prove that some work has been done by them (hence, the name, proof-of-work).
The network gives to miners a mathematical puzzle that is difficult to solve but easy to verify computationally. The miner uses computational power to solve the stated math problem in order to produce the valid block. After the challenge is completed, miner submits his work to other nodes’ for validation. In return the miner who found a block first gets a block reward and transaction fees included to this block.
Note: The difficulty of such mathematical puzzle increases with the growing number of miners. With the increased difficulty it becomes impossible to mine individually, thus, miners have to join mining pools.
About the puzzle that miners need to solve
The Bitcoin cryptocurrency has a cryptographic proof-of-work hash function - SHA 256d. It is a standard mathematical algorithm that converts inputs into outputs. Usually, it is really computationally-easy to get the output by putting the input into the function. E.g. from 1+2+3+4 we get 10. But if we set the challenge vice versa knowing only the output we will have a number of different variants of inputs: 9+1, 8+2, 7+3, 6+4, 5+5, etc. The challenge in a mathematical puzzle is that miner needs to find such input that will satisfy the specific output.
Note: The specific output is a digital value of a block header’s hash - an identifier of a block that has to start with a certain number of zeros.
For solving the puzzle, a miner searches a block nonce. The one who finds it first is a winner. The efficiency of miner depends on its speed in searching the right nonce.

laundering bitcoin bitcoin tm In the financial world the applications are more obvious and the revolutionary changes more imminent. Blockchains will change the way stock exchanges work, loans are bundled, and insurances contracted. They will eliminate bank accounts and practically all services offered by banks. Almost every financial institution will go bankrupt or be forced to change fundamentally, once the advantages of a safe ledger technology without transaction fees are widely understood and implemented. After all, the financial system is built on taking a small cut of your money for the privilege of facilitating a transaction. Instead of paying high transaction fees to the banks and taking several days for payments to settle and clear, they can just transact between each other on blockchain-based exchanges with ease and at no time. Bankers will become mere advisers, not gatekeepers of money. Stockbrokers will no longer be able to earn commissions and the buy/sell spread will disappear.How Does a Blockchain Work?bitcoin slots cubits bitcoin bitcoin мавроди bitcoin кошелек bitcoin win bitcoin блок эфир ethereum bitcoin project blender bitcoin torrent bitcoin опционы bitcoin 999 bitcoin epay bitcoin
