Ravencoin is a use case specific blockchain designed to carry statements of truth about who owns what asset. It aims to implement a blockchain which is optimized specifically for the use case of transferring assets such as tokens from one holder to another. Ravencoin is a protocol based on a fork of the Bitcoin code which adds features specifically focused on allowing tokens to be issued on the Ravencoin blockchain. These tokens can have whatever properties the issue of the token decides - so they can be limited in quantity, named and be issued as securities or as collectibles.
