Cryptocurrencies

Cryptocurrency is a digital means of exchange that uses cryptography and shared transaction ledgers to create a secure, anonymous, traceable and potentially stable monetary system. Cryptocurrencies are named such because of their use of cryptography. Cryptography is the study of the methods of encrypting information, primarily with the intention of sending a message securely and privately but also for tasks such as data security and authentication. Cryptocurrencies incorporate many of the technologies and theories developed by cryptographers in order to create a digital exchange system that is resistant to both censorship and fraud.
