Clams is a peer to peer digital currency. Unlike many other currencies which have pre-mines and ICOs, Clams is fairly distributed. It was distributed to Bitcoin, Litecoin and Doge holders in 2014. Clams are secured by proof of work. Users need to lock clams and keep the wallet running in the background. When every minute a new block is created, these stakers get paid in clams. Privacy features are being worked on. By not using proof of work, Clam saves a lot of electricity and does not hurt the environment.
