Carl Freer A cryptocurrency (or crypto money) is an electronic asset designed to work as a medium of exchange which uses cryptography to secure its transactions, to control the production of additional components, and also to check the transfer of resources. Cryptocurrencies are a type of digital monies, alternate currencies and digital currencies. Cryptocurrencies utilize decentralized control as opposed to centralized electronic money and central banking methods. The decentralized management of every cryptocurrency works via a blockchain, and it will be a public transaction database, functioning as a distributed ledger. Bitcoin, born in 2009, was the initial decentralized cryptocurrency. Since that time, numerous other cryptocurrencies are produced. These are frequently called altcoins, as a blend of alternate coin. Decentralized cryptocurrency is made by the whole cryptocurrency system jointly, at a speed that's defined when the system is made and which is known. In centralized banking and economic systems such as the Federal Reserve System, company boards or authorities control the source of money by printing units of fiat currency or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments can't create new units, and have not so far provided financing for some other firms, banks or corporate entities which hold asset value quantified inside. The inherent technical system upon which decentralized cryptocurrencies are based was generated by the group or person called Satoshi Nakamoto. As of September 2017, over a thousand cryptocurrency specifications exist; many are very similar to and derive from the very first fully executed decentralized cryptocurrency, bitcoin. Within cryptocurrency systems the security, ethics and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: members of the general public using their computers to help validate and timestamp transactions, adding them into the ledger in accordance with a certain timestamping scheme. Miners have a financial incentive to keep the safety of a cryptocurrency ledger. Most cryptocurrencies are made to slowly decrease production of currency, putting an ultimate cap on the whole amount of currency that will be in flow, mimicking valuable metals. In comparison with normal currencies held by financial institutions or stored as cash on hand, cryptocurrencies can be more problematic for seizure by law enforcement. This difficulty is derived from leveraging cryptographic technology. Carl Johan Freer
