Cosmos is a cross-chain protocol that is working to establish a standardized way for blockchains to inter-operate. It has been called the internet of blocchains. Cosmos is building a standardized protocol for multiple blockchains to operate freely together, and allow transfers of value between them. Cosmos is made up of a network of blocckhains called zones. Each of these zones will be powered by a the Tendermint consensus protocol. Cosmos will act as a hub, that ties the zones together and manages their coordination. The Cosomos token called ATOM was released in an ICO that raised $53 million, but it will not be traded until the platform is launched.

Mercury Token is a Waves-based token that was created to facilitate cross-chain communication, and timestamping, between the Waves blockchain and the Jupiter blockchain.

Kava’s multi collateral CDP system allows users to collateralize a variety of assets so that they can increase their exposure to favorable trading conditions in volatile markets.
