$ATOM is the native cryptocurrency of the Cosmos Hub, the central blockchain of the Cosmos network.

Cosmos is often called the "Internet of Blockchains" because it connects independent blockchains (called "zones") so they can share data and trade assets safely using its Inter-Blockchain Communication (IBC) protocol

Key Features

Interoperability:
It solves network isolation by letting separate blockchains talk to one another without a central intermediary.
Supply Model: $ATOM uses an inflationary model without a fixed maximum supply cap, adjusting token issuance based on the overall staking ratio.
