A universe of limitless possibilities

Introduction to Cosmos

Enjoy an introduction to the main components of the Cosmos SDK.

From Tendermint to the modules, keepers, queries, and transactions in Cosmos, a whole universe is waiting to be discovered.

As all blockchain ecosystems keep on growing and maturing, product stacks and terminologies evolve. Thus, please be aware that Cosmos is also known as the Interchain. The terms "Cosmos", "Cosmos Ecosystem", and "Interchain" are synonymous with each other, and the various tools available to developers ("the stack") can be referred to collectively as the Interchain Stack.

# In this chapter
