The Raven code is free and open source, it is a x16r mineable coin with a strong support team on Github. The development team prides itself on the coin being fast, taking less than 1 minute to solve a block with users paying minimal fees. Raven claims on their Medium page their purpose is simple, “to efficiently handle one specific function: the transfer of assets from one party to another.”
