Cosmos

Cosmos, the internet of blockchains, is an inter-chain ecosystem on which blockchains can quickly scale and interoperate. Cosmos is a complete ecosystem of tools for constructing interoperable application-specific chains. Its main components are the SDK (Cosmos Software Development Kit), Tendermint, the IBC (Inter-Blockchain Communication Protocol), and the Cosmos Hub. All blockchains built on Tendermint and the Cosmos tech stack can communicate and exchange assets and data thanks to the IBC. The Cosmos Hub is the main Cosmos blockchain, and other Cosmos SDK blockchains can communicate with it through IBC. Itserves as the main economic centre among the IBC-connected chains composing the Cosmos ecosystem, and provides important services such as Interchain Security to various project. ATOM is the native token of the Cosmos Hub blockchain; it can be used for trading, staking, and governance. By staking ATOM, stakers earn inflationary rewards as well as tokens of chains secured through interchain security, such as Neutron.
