The Cosmos network has a Proof of Stake (PoS) blockchain mainnet and several customizable blockchains called Zones.
Cosmos Hub, the primary blockchain in Cosmos’ internet of blockchain, transports assets and data between linked Zones while also providing a common layer of security. All the Zones work together using Tendermint, the novel consensus mechanism adopted by Cosmos.
Additionally, the Cosmos network is divided into three layers:
Networking – Allows hub blockchains to connect with transaction confirmations and other consensus messages.
Application – Notifies the network of changes in transaction and balance status.
Consensus – Determines how nodes agree to add new transactions.
A range of open-source tools and apps integrate these three levels into an SDK that developers can use to create their own blockchain. Tendermint allows blockchain developers to focus solely on the application layer, saving them time and money.
