Direct TV and Dish TV have just recently announced that they will begin accepting Bitcoins as payment for their TV subscriptions. So just exactly what is a Bitcoin?
Bitcoin is a relatively new electronic payments system described as a decentralized peer-to-peer system. Unlike other electronic payment systems, such as PayPal,it also has its own currency — a virtual denomination also known as Bitcoins. Bitcoins are known by various names including virtual currency,electronic money,or crypto-currency. The Bitcoin system is driven by a concept called block chain, a public record of all transactions carried out within the Bitcoin network. The transactions are recorded in a public record that is collectively maintained by everyone who uses the currency. Bitcoins are stored in a digital wallet when they are received. The wallet can be cloud-based or on a local system to maximize security.Who created Bitcoin? A person calling himself Satoshi Nakamoto,published the rules to the Bitcoin portal in 2008. The network was launched in 2009; however,no one really knows the true identity of Nakamoto.How to create (earn) Bitcoins. According to Wikipedia,“Bitcoins are created as a reward for payment processing work in which users who offer their computing power,verify and record payments into a public ledger. Called mining, individuals engage in the activity in exchange for transaction fees and newly minted Bitcoins. Mining is the process of adding transaction records to Bitcoin’s public ledger of past transactions. The 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. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady.” Bitcoins can also be obtained in exchange for products, services,or other currencies.Pros
