CryptoCurrency
Definition of CryptoCurrency
A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.[1][2][3] Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.
Bitcoin, created in 2009, was the first decentralized cryptocurrency.[4] Since then, numerous cryptocurrencies have been created.[5] These are frequently called altcoins, as a blend of bitcoin alternative.[6][7][8] Bitcoin and its derivatives use decentralized control[9] as opposed to centralized electronic money/central banking systems.[10] The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger.
History CryptoCurrency
In 1998, Wei Dai published a description of "b-money", an anonymous, distributed electronic cash system.[19] Shortly thereafter, Nick Szabo created "bit gold".[20] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[13][21] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[22] IOTA was the first cryptocurrency not based on a blockchain, and instead uses the Tangle.[23][24] Many other cryptocurrencies have been created though few have been successful, as they have brought little in the way of technical innovation.[25] On 6 August 2014, the UK announced its Treasury had been commissioned to do a study of cryptocurrencies, and what role, if any, they can play in the UK economy. The study was also to report on whether regulation should be considered.
