Krypton

Krypton is a decentralized bulletin board of products or posts. The program, runs on each user's mobile phone so there is no central server. The tokens only exist because of the other users on the system. You can view anyone’s tokens but can only edit the ones you own. The system is kind of like a marketplace but built as a blockchain system. There are a total of 25,000 tokens on the system for people to use. That number cannot be changed unless the users of the system choose to update the protocol.
