Verifiable timestamps and ordering of events
Developers use hbars to pay for network services, such as running a smart contract, storing a file, or transferring cryptocurrency. For each transaction submitted to the network, hbars are used to compensate network nodes for bandwidth, compute, and storage.
Developers can incorporate hbars into applications to facilitate peer-to-peer payments and micropayment (<$0.01) business models.
Hedera’s proof-of-stake public network uses hbars, which are staked or proxy staked (coming soon) to a network node, to weight votes on transactions when reaching consensus.
Weighted voting with hbars makes it difficult and expensive for a bad actor to maliciously affect consensus — it would require them to own and stake over one-third of the network’s total supply of cryptocurrency, which will not be possible for the first 5 years.
The 3rd generation public ledger
Bitcoin pioneered decentralized infrastructure and Ethereum brought programmability. But earlier proof-of-work blockchains consume massive amounts of energy and process transactions slowly in order to achieve acceptable levels of security. Heavy bandwidth consumption by these technologies leads to expensive fees, even for a simple cryptocurrency transaction.
The Hedera proof-of-stake public network, powered by hashgraph consensus, achieves the highest-grade of security possible (ABFT), with blazing-fast transaction speeds and incredibly low bandwidth consumption. By combining high-throughput, low fees, and finality in seconds, Hedera leads the way for the future of public ledgers.

Applications and microservices that use a public ledger provide greater transparency and trust than ever before. This makes entirely new things possible, like a music streaming service paying artists directly or a disintermediated ad network that doesn't require audits. A fairer, more secure, digital future is being decentralized on Hedera. Make it yours.
Every node on Hedera’s proof-of-stake network has a weighted influence on consensus — that weight is proportional to the amount of hbars staked to a node. Proxy staking allows those who own hbars, but aren’t operating a node, to stake their hbars to someone else’s node. Earnings are split between the node operator and owners of the proxy staked hbars, earning the proxy staker a small share of transaction fees. When proxy staked, hbars are not locked-up or bonded, as is common in other networks, and proxy stakers retain the ability to transact their HBAR however they'd like.

HBAR (ℏ) may be available for purchase by developers and users to build and utilise applications on the network at the exchanges and OTCs listed in the Buying Guide.
Our Hedera Hashgraph corporate logo is a bold, uppercase HBAR (Ħ), but our currency symbol is a lower case, italicized HBAR (ℏ). The written way to express Hedera cryptocurrency is hbars, and is equivalent to writing US dollars. It can also be expressed as HBAR, which is equivalent to writing USD.
