Bitcoin is a form of digital currency, created and held electronically. No one controls it. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems to create Bitcoins.
It’s the first example of a growing category of money known as cryptocurrency. There is already more than 600 Crypto Currencies all around the world.
Bitcoins are impossible to be counterfeited or inflated. You can use them to send or receive any amount of money, with anyone, anywhere in the world, at very low cost.
Bitcoin payments are impossible to be blocked, and bitcoin wallets can’t be frozen. Short of turning off the entire world's internet, and keeping it turned off, the Bitcoin network is unstoppable and un censor-able.
Bitcoin is different than any currency you’ve used before, so it's very important to understand some key points. Unlike government issued money, that can be inflated at will, the supply of bitcoin is mathematically limited to twenty one million bitcoins, and that can never be changed.
What is Bitcoin Mining ?
Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid.
This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.
This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.
Un-like cloud mining where you can buy hashpower for the mining process , when you mine crypto-currency , you need computing hardware and software to be able to mine. Read More >>>
