Hedera is a high-performance Proof of Stake (PoS) smart contract platform engineered for secure, scalable, and decentralized applications. Unlike traditional blockchains that rely on linear chains of blocks, Hedera leverages a unique directed acyclic graph (DAG) consensus mechanism known as the Hashgraph Gossip Protocol. This innovative architecture enables faster transaction finality, greater throughput, and improved energy efficiency—making Hedera a compelling choice for enterprise-grade blockchain solutions.
Designed to overcome the long-standing blockchain trilemma—the challenge of balancing decentralization, security, and scalability—Hedera provides a stable foundation for real-world applications in industries such as healthcare, supply chain, financial services, and decentralized finance (DeFi). It also supports emerging digital ecosystems like central bank digital currencies (CBDCs), stablecoins, and the metaverse.
At the heart of the network is HBAR, its native utility token, which powers transactions, secures the network through staking, and enables governance participation.
Who Created Hedera?
Hedera was founded in 2017 by American technologists Leemon Baird and Mance Harmon, both veterans in software development, cybersecurity, and artificial intelligence. Together, they also launched Swirlds Labs, the company responsible for developing the underlying Hashgraph technology that powers Hedera.
The project is overseen by the Hedera Governing Council, a decentralized body composed of up to 39 globally recognized enterprises—including Google, Dell, and IBM—ensuring balanced oversight and long-term network stability. This council governs protocol upgrades, key decisions, and validator operations.
Approximately 11% of the total HBAR supply was initially distributed to accredited investors through a Simple Agreement for Future Tokens (SAFT) sale, reinforcing early institutional confidence in the platform’s potential.
How Does Hedera Work?
Hedera operates through a suite of modular services collectively known as Hedera Network Services. These services are built on top of the Hashgraph Gossip Protocol, enabling secure, asynchronous consensus without sacrificing speed or fairness.
Hedera Network Services
The platform is structured around three core service layers:
- Hedera Token Service (HTS): Enables seamless creation, management, and transfer of both fungible tokens and non-fungible tokens (NFTs) directly on the network—without requiring smart contracts.
- Hedera Consensus Service (HCS): Provides a tamper-proof audit trail for data integrity. It allows organizations to timestamp and verify events such as supply chain updates, governance decisions, or legal agreements with cryptographic proof.
- Hedera Smart Contract Service: Supports deployment of smart contracts using popular programming languages like Solidity, enabling developers to build decentralized applications (dApps) with familiar tools and frameworks.
These services are unified under Hedera’s consensus engine—the Hashgraph Gossip Protocol—which ensures all nodes agree on the order and timing of transactions with mathematical certainty.

Hashgraph Gossip Protocol: The Engine Behind Consensus
The Hashgraph Gossip Protocol replaces traditional block validation with a more efficient DAG-based approach. Instead of mining blocks sequentially, nodes "gossip" transaction data randomly across the network. Each node shares what it knows with another random node, rapidly spreading information in parallel.
As data propagates, nodes record timestamped events that capture when they received and verified each piece of information. Using a mathematical voting process called virtual voting, nodes independently determine consensus without needing to exchange additional messages—drastically reducing latency.
This method achieves asynchronous Byzantine Fault Tolerance (aBFT), meaning the network remains secure even if some nodes act maliciously or fail. Transactions are finalized in seconds with near-zero fees and full finality—no forks or rollbacks.
Key Use Cases of Hedera
Hedera’s design makes it ideal for large-scale, mission-critical applications:
- Enterprise Supply Chain Tracking: Companies use HCS to log every stage of product movement with immutable timestamps.
- Healthcare Data Integrity: Patient records and clinical trial data can be securely shared and verified across institutions.
- Financial Infrastructure: Banks and fintechs leverage HTS for issuing stablecoins and CBDCs with regulatory compliance.
- Decentralized Identity (DID): Users maintain control over personal data while proving identity securely.
- DeFi & NFTs: Developers build low-cost, high-speed financial dApps and digital collectibles.
- Play-to-Earn Gaming & Metaverses: Game studios utilize fast finality and low fees to support real-time in-game economies.
Additionally, Hedera supports permissioned (private) blockchain networks for institutions requiring controlled access—while still interfacing securely with its public ledger when needed.

How Does HBAR Work?
HBAR is the lifeblood of the Hedera ecosystem. It serves multiple critical roles:
- Pays for transaction and smart contract execution fees
- Secures the network via staking
- Grants voting rights in network governance
Proof of Stake with a Twist
While Hedera uses a Proof of Stake (PoS) model, it diverges from traditional implementations. There's no requirement to "lock" or "bond" tokens. Instead, an account’s entire HBAR balance is automatically staked when associated with a validator node.
To run a validator node independently, a minimum stake of approximately 460 million HBAR is required (as of 2023), with a cap around 1.85 billion per node. Currently, 27 council-member enterprises operate validator nodes, with expansion planned to 39 members.
For individual users who can’t meet these thresholds, proxy staking allows delegation of HBAR to existing validators. In return, stakers earn a share of transaction fee rewards proportional to their contribution—promoting broader participation in network security.
HBAR Token Distribution
The total supply of HBAR is fixed at 50 billion tokens, all minted at genesis and released over a 15-year vesting schedule. The allocation is as follows:
- 23.9% – Ecosystem & open-source development
- 22.26% – Early investors (SAFT purchasers)
- 14.77% – Network governance and operations
- 7.74% – Initial development and licensing
- 31.33% – Reserved for future allocation via Hedera Council votes
This structured distribution supports long-term sustainability and incentivizes ongoing innovation within the ecosystem.
Frequently Asked Questions (FAQ)
Q: Is Hedera a blockchain?
A: Technically, no. Hedera uses a directed acyclic graph (DAG) called Hashgraph instead of a traditional linear blockchain. However, it functions similarly as a distributed ledger with smart contract capabilities.
Q: What makes Hedera faster than Ethereum or Bitcoin?
A: Thanks to its Hashgraph consensus, Hedera achieves finality in 3–5 seconds with throughput exceeding 10,000 transactions per second—far surpassing most blockchain networks.
Q: Can I stake HBAR without running a node?
A: Yes. You can participate in proxy staking by delegating your HBAR to an existing validator and earning rewards passively.
Q: Is HBAR used only for fees?
A: No. Beyond transaction costs, HBAR plays key roles in staking, governance voting, and securing the network.
Q: How does Hedera ensure decentralization with corporate council members?
A: The Governing Council limits any single entity’s influence by capping membership at 39 diverse global organizations. No member holds disproportionate power over upgrades or policy.
Q: Can Hedera support NFTs and DeFi projects?
A: Absolutely. With HTS and smart contract support, developers easily launch NFT marketplaces, lending protocols, and DeFi platforms with minimal gas fees.
