Krypton

Krypton is a decentralized bulletin board of products or posts. The program, like other crypto currencies, 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 you can only edit the ones you own.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.

Features:

No selling fees.

Users all over the world can access your items for sale.

You can update your listings anytime using your private key.

Because no site is hosting the listings they cannot be taken down.

Tokens are not free so the quality of products should be high.

Tokens can be linked into other websites to become ad space.

Add search terms to your listings with others to create decentralized stores.
