Bitcoin is a payment system invented by Satoshi Nakamoto,note who published the invention in 2008 and released it as open-source software in 2009. The system is peer-to-peer; users can transact directly without needing an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. The ledger uses its own unit of account, also called bitcoin.note The system works without a central repository or single administrator, which has led the US Treasury to categorize it as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed.note Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value.
Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and the miners are rewarded with transaction fees and newly created bitcoins. Besides mining, bitcoins can be obtained in exchange for different currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.
Bitcoin as a form of payment for products and services has grown, and merchants have an incentive to accept it because fees are lower than the 2–3% typically imposed by credit card processors. Unlike credit cards, any fees are paid by the purchaser, not the vendor. The European Banking Authority and other sources have warned that bitcoin users are not protected by refund rights or chargebacks. Despite a big increase in the number of merchants accepting bitcoin, the cryptocurrency doesn’t have much momentum in retail transactions.
The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and media. Criminal activities are primarily centered around black markets and theft, though officials in countries such as the United States also recognize that bitcoin can provide legitimate financial services.
The satoshi is currently the smallest unit of the bitcoin currency recorded on the block chain. It is a one hundred millionth of a single bitcoin (0.00000001 BTC). The unit has been named in collective homage to the original creator of Bitcoin, Satoshi Nakamoto.
All amounts in the block chain are denominated in satoshi before being converted for display. The source code also uses satoshi when specifying an amount of bitcoin. When displaying an extremely fine fraction of a bitcoin, as in a contemporary faucet, the amount is displayed in satoshi for readability.As of August 2015, 1 US cent is worth approximately 4400 satoshi.
