Cosmos (ATOM) Token
ATOM is the native utility and governance token of the Cosmos Hub, the central hub of the 'Internet of Blockchains'.
Tokenomics and Roles: 1. Staking: ATOM holders delegate to validators to earn rewards (~10-20% APR). 2. Slashing: Malicious validators lose a portion of their staked ATOM. 3. Governance: 1 ATOM = 1 Vote on the Hub. 4. Fees: Used to pay for transactions on the Hub and cross-chain operations.

Think of the internet as a collection of different islands that couldn't talk to each other. Cosmos is the [bridge](/ja/terms/bridge) system that connects them. ATOM is the special 'passport' and '[governance](/ja/terms/governance) stamp' for the main island (The Hub). If you hold ATOM, you help guard the [bridges](/ja/terms/bridges) and you get to vote on how the bridge system should be improved.
🤓 Expert Deep Dive
Technically, ATOM's utility has evolved with 'Interchain Security' (ICS). Validators on the Cosmos Hub can use the security provided by staked ATOM to secure other blockchains (Consumer Chains). This creates a 'Value Accrual' mechanism for ATOM as it earns fees from multiple chains simultaneously. The token uses a dynamic inflation model that adjusts based on the percentage of total supply staked, aiming for a consistent security threshold. The IBC protocol allows ATOM to be transferred seamlessly across hundreds of other sovereign blockchains in the 'Interchain'.
