Hedera Hashgraph is a cutting-edge public distributed ledger that stands out in the blockchain landscape as a third-generation proof-of-stake network. Unlike traditional blockchain platforms, Hedera is powered by a unique consensus mechanism called hashgraph, enabling faster, fairer, and more energy-efficient transaction processing. As an open-source platform, Hedera supports Ethereum Virtual Machine (EVM)-compatible smart contracts and native tokenization, making it highly accessible to developers familiar with Ethereum’s ecosystem.
The network is secured and maintained by HBAR, its native cryptocurrency. HBAR plays a critical role in network operations—developers use it to pay for transaction fees, while participants can stake HBAR to help secure the network and earn rewards. Governed by the Hedera Governing Council, a decentralized body of up to 39 global organizations—including Google, IBM, LG, Ubisoft, and University College London—Hedera ensures no single entity holds undue influence over the network or its tokenomics.
How Does Hashgraph Consensus Work?
At the heart of Hedera’s innovation lies the hashgraph consensus algorithm, a breakthrough alternative to traditional blockchain consensus models like Proof of Work (PoW) and even some Proof of Stake (PoS) systems.
In conventional blockchains, nodes compete to add new blocks to a linear chain. When two blocks are created simultaneously, one must be discarded to prevent forking—leading to inefficiencies and slower finality. Hashgraph, however, eliminates this issue by using a directed acyclic graph (DAG) structure where every transaction is recorded and validated without discarding any data. This results in higher throughput and near-instant finality.

Hashgraph achieves consensus through gossip about gossip and virtual voting:
- Nodes share transaction information with each other randomly ("gossip").
- Each node records not only its own transactions but also the history of how other nodes received information ("gossip about gossip").
- Using this shared history, nodes virtually determine agreement on transaction order without extensive communication—enabling fast, secure consensus.
This method provides strong mathematical guarantees rooted in Byzantine fault tolerance, ensuring security even if some nodes act maliciously. Transactions are confirmed in under 5 seconds, compared to 10–20 seconds on Ethereum and up to 60 minutes on Bitcoin.
Performance Advantages Over Traditional Blockchains

Hedera delivers exceptional performance:
- Throughput: Capable of processing over 10,000 transactions per second (TPS).
- Fees: Average transaction cost is just $0.0001, significantly lower than most Layer 1 networks.
- Speed: Final settlement in under 5 seconds.
- Energy Efficiency: Each transaction consumes only 0.00017 kWh, making Hedera a carbon-negative network—far greener than PoW chains.
These attributes make Hedera ideal for high-frequency applications such as micropayments, supply chain tracking, decentralized identity, and real-time financial settlements.
HBAR Tokenomics and Supply Model
HBAR is central to Hedera’s economic design. With a fixed total supply of 50 billion tokens, there will never be inflation beyond this cap. All HBAR tokens were pre-minted at launch and are gradually released from the Hedera Treasury under the oversight of the Governing Council.
As of 2022, approximately 16 billion HBAR remained in the treasury. The initial allocation was distributed as follows:
- Swirlds (Creators of Hashgraph): 3.9 billion HBAR
- Founders & Early Executives: ~6.9 billion HBAR
- Employees & Service Providers: 7 billion HBAR set aside; ~2.2 billion already distributed
- Private Sale Agreements (e.g., SAFTs): 8.6 billion HBAR
- Ecosystem Development Fund: 11.9 billion HBAR allocated to support developer growth, grants, and platform adoption
This structured release ensures long-term sustainability and prevents market flooding. Staking HBAR allows users to participate in network security and earn a share of transaction fees—a key incentive for decentralization.
Founding Team and Leadership Evolution
Hedera was co-founded in 2018 by Dr. Leemon Baird and Mance Harmon, both veterans in distributed systems and cybersecurity. Their journey began in 2015 with the creation of Swirlds, a platform for building fully decentralized applications without centralized servers.
Dr. Baird invented the hashgraph consensus algorithm, which became the foundation of Hedera’s high-performance ledger. Shortly after Hedera’s formation, Swirlds licensed the technology to the network.
Initially, Baird served as Chief Scientist and Harmon as CEO. However, in April 2022, both stepped down from their executive roles to lead Swirlds Labs, a new entity focused on advancing hashgraph research and core protocol development. Despite leaving day-to-day management, they remain influential as representatives on the Hedera Governing Council.
Their transition reflects Hedera’s commitment to decentralized governance—shifting control from individuals to a globally diverse council of industry leaders.

Frequently Asked Questions (FAQ)
Q: Is Hedera a blockchain?
A: Technically, no. Hedera uses a hashgraph consensus algorithm built on a DAG structure rather than a traditional blockchain. While it serves similar functions—secure, decentralized transaction recording—it does so more efficiently and with greater fairness.
Q: Can I stake HBAR tokens?
A: Yes. Staking HBAR helps secure the network and entitles participants to earn rewards from transaction fees. Users can delegate their stake to trusted nodes or run their own validator.
Q: How is Hedera governed?
A: Through the Hedera Governing Council, composed of up to 39 global organizations from various industries. Council members have equal voting rights, ensuring balanced, decentralized decision-making.
Q: Is Hedera environmentally friendly?
A: Absolutely. Hedera operates on a proof-of-stake model with minimal energy consumption—each transaction uses just 0.00017 kWh—and is officially certified as carbon negative.
Q: What types of applications run on Hedera?
A: The network supports smart contracts, file storage, tokenization, decentralized IDs (DID), NFTs, DeFi protocols, and supply chain solutions—all with low latency and predictable costs.
Q: Where can I buy HBAR?
A: HBAR is listed on several major cryptocurrency exchanges. You can acquire it through secure trading platforms that support digital assets.
