Hedera Hashgraph (HBAR) is used in several ways within the Hedera network:

1. Transaction Fees: HBAR is used to pay fees for transactions on the network. This includes fees for creating and executing smart contracts, minting tokens, and other operations.

2. Staking and Network Security: HBAR is staked to network nodes to provide a weighted voting system for validating transactions. This is part of the proof-of-stake consensus mechanism, which ensures the security and integrity of the network.

3. Developer Tools: HBAR is used by developers to build and deploy decentralized applications (dApps) on the Hedera network. This includes using HBAR for gas fees, similar to how Ethereum uses ETH for gas fees.

4. Tokenization: HBAR can be used to create and manage fungible and non-fungible tokens (NFTs) for various applications, such as governance, digital collectibles, or in-app payments.

Overall, HBAR plays a central role in facilitating transactions, ensuring network security, and enabling the development of decentralized applications on the Hedera Hashgraph network.
