Instead of using a centralised digital currency and central banking system, cryptocurrencies maintain a decentralised control. The decentralised control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database. The decentralised structure allows them to exist outside the governments control.
Bitcoin is considered as the first decentralised cryptocurrency; it was originally released as open-source software in 2009 by an individual or group known by the alias ""Satoshi Nakamoto.”. Since Bitcoins release, over 4,000 alternative variants of bitcoin, or other cryptocurrencies have been introduced. It still remains the most popular and the most valuable among others.
Cryptocurrencies are ways that allow for the secure payments online which are titled in terms of virtual ""tokens,"" which are depicted by ledger entries internal to the system. ""Crypto"" refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
