BlackCoin (BLK)

BlackCoin (BLK) is a cryptocurrency that was launched in March 2014 by the former Bitcoin developer Rat4 in collaboration with Pavel Vasin. It is an open source, peer-to-peer digital currency that is secured by a Proof-of-Stake (PoS) algorithm. The development team behind BlackCoin consists of several developers and volunteers from across the world. What makes BlackCoin unique is its use of the PoS consensus system, a first for any cryptocurrency. This system allows for near instantaneous transactions without the need for proof of work mining, making it unique compared to other popular cryptocurrencies such as Bitcoin which require mining for processing transactions. BlackCoin also features security features such as replay protection, which adds further protection to the network. Where BlackCoin is used is up to the users of the network, as it is designed to be used in any way that traditional currency is used. This could include shopping at stores or online, sending money to others, or even donations to charitable causes. As a cryptocurrency, BlackCoin also offers a degree of anonymity since it is decentralized and operates on a public ledger. BlackCoin can be purchased and sold on several exchanges such as Bittrex, Upbit, Kraken, and Poloniex. It is also accepted by several online merchants, such as OpenBazaar. One note is that many of the exchanges and merchants will not accept purchase or deposits of BlackCoin directly, but instead require that it is first exchanged for another cryptocurrency, such as Bitcoin. In conclusion, BlackCoin is a unique cryptocurrency that utilizes a PoS consensus system instead of traditional proof of work mining. It can be used just like any other currency, and is traded on several popular exchanges as well as accepted by online merchants. Although it is not widely accepted directly, BlackCoin can be exchanged for other currency and used for transactions.
