Hedera (HBAR) is a public cryptocurrency network that uses the innovative Hashgraph consensus algorithm, a high-performance alternative to traditional Proof of Work (PoW) and Proof of Stake (PoS) systems. Designed for enterprise-grade scalability, Hedera supports decentralized applications (dApps), smart contracts, and asset tokenization with unparalleled speed, cost-efficiency, and energy sustainability.
Key Features of Hedera
- Hashgraph Consensus: A patent-pending, asynchronous Byzantine Fault Tolerant (aBFT) algorithm enabling 10,000+ transactions per second (TPS) with finality in seconds.
- Fixed Supply: HBAR’s total supply is capped at 50 billion tokens, ensuring predictable inflation.
- Multi-Language Smart Contracts: Supports Solidity, Java, and Python for flexible dApp development.
- Governing Council: Managed by 39 global organizations (e.g., IBM, Google, Boeing) to ensure decentralized governance.
- Carbon-Negative: Achieved through partnerships with sustainability initiatives like the Hedera Guardian Project.
Who Created Hedera and When Was It Launched?
Hedera was co-founded in 2018 by Dr. Leemon Baird (inventor of Hashgraph) and Mance Harmon, both veterans in cybersecurity and distributed systems. Baird’s PhD research at Carnegie Mellon laid the groundwork for Hashgraph, while Harmon’s leadership at Swirlds Inc. (founded in 2017) drove its commercialization. The mainnet launched in September 2019, positioning Hedera as a competitor to Ethereum and other Layer 1 blockchains.

How Does Hedera’s Hashgraph Consensus Work?
Gossip Protocol
Nodes randomly share transaction data ("gossip") and metadata ("gossip about gossip"), creating a Directed Acyclic Graph (DAG). This ensures rapid, secure dissemination of information without mining.
Virtual Voting
Nodes asynchronously vote on event "fame" to achieve consensus. Transactions are finalized once deemed "famous" by a supermajority of nodes—eliminating forks and ensuring aBFT security.
Governance Model
Only Hedera Governing Council members operate consensus nodes, balancing decentralization with enterprise-grade reliability. Mirror nodes enable public access to historical data.
Hedera vs. Other Blockchains: Key Differences
| Feature | Hedera (HBAR) | Bitcoin (BTC) | Ethereum (ETH) |
|---|---|---|---|
| Consensus | Hashgraph (aBFT) | PoW | PoS |
| TPS | 10,000+ | 7 | 15–30 |
| Energy Use | Carbon-negative | High | Moderate |
| Governance | Council-based | Miner-driven | Community-driven |
| Smart Contracts | Solidity/Java/Go | Limited (Script) | Solidity/Vyper |

FAQ
Q: How is Hedera different from Ethereum?
A: Hedera uses Hashgraph (not blockchain) for higher TPS and lower fees, but sacrifices some decentralization.
Q: What is HBAR’s max supply?
A: 50 billion tokens, with circulating supply at ~33 billion (2024).
Q: Can I stake HBAR?
A: Yes! Earn rewards via native staking or exchanges like OKX.
Q: Is Hedera eco-friendly?
A: Yes—its proof-of-stake-like model uses minimal energy.
