What It's For
CloudCoin is the money layer underneath a growing family of products. The first one people meet is QMail — private, unsurveillable messaging where your mailbox is backed by a coin, and where you can charge a small fee to receive mail from strangers. That single idea kills spam, because spam only works when sending is free. Once you have digital cash that is genuinely bearer-held, private, fast, and needs no bank, you can pay a few cents to read one article, tip across a border without a wire transfer, let machines pay each other automatically, or simply hand money to another person the way humans did for four thousand years.
