Digital Money




Origins of digital currencies date back to the 1990s Dot-com bubble. One of the first was E-gold, founded in 1996 and backed by gold. Another known digital currency service was Liberty Reserve, founded in 2006; it let users convert dollars or euros to Liberty Reserve Dollars or Euros, and exchange them freely with one another at a 1% fee. Both services were centralized, reputed to be used for money laundering, and inevitably shut down by the US government.[3] Q coins or QQ coins, were used as a type of commodity-based digital currency on Tencent QQ's messaging platform and emerged in early 2005. Q coins were so effective in China that they were said to have had a destabilizing effect on the Chinese Yuan or RMB currency due to speculation.[4] Recent interest in cryptocurrencies has prompted renewed interest in digital currencies, with bitcoin, introduced in 2009, becoming the most widely used and accepted digital currency.

Types of digital currencies

Virtual currency


A virtual currency has been defined in 2012 by the European Central Bank as "a type of unregulated, digital money, which is issued and usually controlled by its developers, and used and accepted among the members of a specific virtual community". The US Department of Treasury in 2013 defined it more tersely as "a medium of exchange that operates like a currency in some environments, but does not have all the attributes of real currency". The key attribute a virtual currency does not have according to these definitions, is the status as legal tender.

Cryptocurrency


A cryptocurrency is a type of digital token that relies on cryptography for chaining together digital signatures of token transfers, peer-to-peer networking and decentralization. In some cases a proof-of-work scheme is used to create and manage the currency.[6][7][8][9]

Digital currency exchange

Digital currency exchanges (DCEs) or bitcoin exchanges are businesses that allow customers to trade digital currencies for other assets, such as conventional fiat money, or different digital currencies.[1] They can be market makers that typically take the bid/ask spreads as transaction commissions for their services or simply charge fees as a matching platform.[1]

How Bitcoin Mining Works

In traditional fiat money systems, governments simply print more money when they need to. But in bitcoin, money isn’t printed at all – it is discovered. Computers around the world ‘mine’ for coins by competing with each other. How does mining take place? People are sending bitcoins to each other over the bitcoin network all the time, but unless someone keeps a record of all these transactions, no-one would be able to keep track of who had paid what. The bitcoin network deals with this by collecting all of the transactions made during a set period into a list, called a block. It’s the miners’ job to confirm those transactions, and write them into a general ledger. Making a hash of it This general ledger is a long list of blocks, known as the 'blockchain'. It can be used to explore any transaction made between any bitcoin addresses, at any point on the network. Whenever a new block of transactions is created, it is added to the blockchain, creating an increasingly le
