Bitcoin, which was invented by an unknown person or a group, which was named Satoshi Nakamoto and was released in 2009 as open source software, is a cryptocurrency and payment system around the world. This is the first decentralized digital currency, because the system works without a central bank or a single administrator. These transactions have been verified by the network nodes and have been registered in a public distribution account called Block Chain.
Due to the decentralized nature of bitcoin, the nation-state network can’t be closed or its technical rules can’t be changed. However, the use of bitcoin can be made criminal and closing exchanges. The legal status of bitcoin is very different from country to country and many of them still remain undefined or changed. Although some countries have explicitly permitted its use and business, others have restricted or restricted it.
Bitcoins have been designed as a reward for a process known as mining. They can be exchanged for other currencies, products and services. Bitcoin has been criticized for the amount of electricity consumed by mining. The combined power consumption will be 166.7 MW per year if all the miners use modern facilities.
According to The Economist “In every ten minutes of mining computers collect a few hundred pending bitcoin transactions (called “block”) and turn them into mathematical puzzles. To find a solution, the first person working on the mine tells others on the network. Other miners should check if the sender of funds has the right to spend money and whether the solution to the puzzle is correct or not. If they provide enough approval from them, the block is added cryptographically to the account holder and the miners move forward for the next transaction (termed as “BlockChain”). The miner found was found as a reward for 25 bitcoins, but only after adding 99 blocks to the account holder. This gives an incentive to all the miners to participate in the system and to validate the transaction.”
