Hedera (HBAR) Cryptocurrency: Comprehensive Overview
Core Technology and Blockchain Architecture
Hedera is a decentralised public network designed for fast, fair, and secure digital interactions. Hedera is not exactly a blockchain. It has its own distinctiveness and works differently. It uses a consensus algorithm called Hashgraph, a form of asynchronous Byzantine Fault Tolerance (aBFT), to achieve high throughput, low fees, and ensure finality in seconds.
Unlike a regular blockchain, which adds blocks of transactions sequentially, Hashgraph employs a Directed Acyclic Graph (DAG) structure. This allows multiple transactions to be processed in parallel, drastically increasing throughput and reducing latency. Two fundamental Hashgraph concepts are: 'gossip about gossip' and 'virtual voting.' The first one, 'Gossip about gossip' refers to nodes sharing not just transactions but also information about how and when those transactions were received. Over time, this forms a history that all nodes can verify. Meanwhile, 'Virtual voting' enables nodes to deduce consensus on transaction order without broadcasting additional messages, a method that boosts both speed and bandwidth efficiency.
Consensus Mechanism and Network Security
Hedera achieves asynchronous Byzantine Fault Tolerance (aBFT), a highly secure consensus model that ensures that even if some network participants are compromised, the ledger remains trustworthy. This property is mathematically proven and offers one of the strongest security guarantees among public DLTs.
Hedera Hashgraph claims it can handle more than 10,000 transactions per second (TPS) — compared to the around 5-20 for most popular proof-of-work (PoW)-based blockchains. Hedera transactions have an average transaction fee of just $0.0001 USD and typically reach finality in under five seconds.
The hedera network uses stake-weighted consensus: node influence in consensus is proportional to the amount of HBAR staked to it, providing Sybil Resistance without energy-intensive mining. While the consensus algorithm is hashgraph aBFT, the economic security model is proof-of-stake (PoS), which is distinct from Proof of Work or Delegated Proof of Stake.
Energy Efficiency and Sustainability
From a sustainability perspective, Hedera is one of the most energy-efficient DLTs in operation. According to Nodiens data from 11 June 2025, Hedera consumes 0.00025 kWh per transaction, far below Ethereum ( 2.95 kWh) or Bitcoin ( 1,087 kWh).
Founding Team and Project History
Hedera was co-founded by Leemon Baird, the inventor of the hashgraph algorithm, and Mance Harmon, a cybersecurity and tech executive. Hedera traces its technical foundation to Dr. Leemon Baird's hashgraph consensus algorithm, first described in 2016 in "The Swirlds Hashgraph Consensus: Fair, Fast, Byzantine Fault Tolerance" (Swirlds paper).
Hedera launch event is held on March 13, 2018 in NYC, drawing 1,000 people live and more than 100,000 livestream viewers. The event unveils Leemon and Mance's vision for a public network – a network to be built on the patented hashgraph algorithm, governed by a Council of up to 39 global enterprises, and guaranteed not to fork. The Hedera mainnet is made openly accessible on September 16, 2019.
The Hedera Governing Council voted to purchase the patent rights to Hashgraph and make the algorithm open source under the Apache License in 2022.
Primary Use Cases and Real-World Applications
The platform offers several major network services. These include: A token service that allows users to easily configure and mint both fungible and non-fungible tokens (NFTs) on Hedera with just a few lines of code. A consensus service that acts as a layer of trust for any application or network that needs a secure, verifiable log of events. Smart contract tools that let developers build powerful and efficient decentralized applications. Decentralized file storage services with features include proof-of-deletion, controlled mutability, and time-based file expiry.
Decentralized Finance (DeFi): Hedera facilitates decentralized finance applications such as stablecoins, lending platforms, and decentralized exchanges (DEXs) through its smart contract capabilities and high throughput. Supply Chain Management: The platform enables transparent and efficient supply chain management solutions, providing real-time tracking, traceability, and authentication of goods. Tokenization: Hedera supports tokenization of assets, allowing for the creation and management of digital representations of real-world assets such as real estate, securities, and collectibles.
Secure Voting Systems – Governments can use Hedera's immutable ledger for election transparency. The potential use cases and applications of the Hedera technology include data integrity and AI, scalable and affordable crypto-payments, treasury management, and seamless tokenization of real-world and digital assets.
Tokenomics: Supply and Distribution
The Hedera Hashgraph token, HBAR, has a maximum total supply of 50 billion units. All 50 billion HBAR tokens were minted at the network launch in August 2018 and moved into the Hedera Treasury.
The tokens are distributed from the Hedera Treasury according to a predetermined schedule. This distribution occurs at discrete intervals, typically at the end of each quarter. The distribution schedule was initially planned to extend over 15 years but was later revised in the Hbar Economics Whitepaper (v3) to span from 2019 to 2025, with an estimated release of 34% of all HBAR by 2025.
As of May 2024, approximately 70% of the total supply is in circulation. The rest is subject to a distribution schedule managed by the Hedera Governing Council.
Inflation and Deflation Mechanics
Fixed Supply: With a fixed total supply of 50 billion tokens, there is no inflation from new token issuance. Token Release Schedule: The release of tokens into circulation is controlled by a predefined schedule, reducing the risk of sudden inflation.
Transaction fees collected in HBAR are not destroyed but instead are used to compensate nodes for their participation in the network. This mechanism does not directly reduce the total supply of HBAR but redistributes existing tokens.
HBAR Token Utility
The native token, HBAR, is used for fees, staking-based security, and EVM gas. HBAR, Hedera's native token, is used to pay for network services, cover transaction fees, secure the network, and power various applications. The token is also staked by validators to secure the proof-of-stake (PoS) consensus algorithm, and rewarded to validators for securing and operating the network.
HBAR holders can stake to network nodes and earn passive rewards without lockups or slashing risk.
Governance Structure
The Hedera Council, composed of up to 39 diverse organizations from various industries and geographies, oversees the network's development and operation. The decentralized governance model ensures that no single entity has undue influence over the network, promoting fairness and transparency.
Hedera mainnet is maintained by governing council members which include companies such as Deutsche Telekom, IBM, FIS Global, and Tata Communications. By 2025, the network had expanded its Governing Council to include 30+ multinational corporations, with projections indicating a further increase to 39 by 2027.

Current Development Activity and Roadmap Highlights
The Canary HBAR ETF (HBR) began trading on the Nasdaq stock exchange on October 28, 2025. Then, on Thanksgiving, while traditional U.S. markets were closed, Archax facilitated a live, out-of-hours transaction of the tokenized Canary HBR ETF.
Launched in March, HashSphere lets organizations deploy private, permissioned networks that connect seamlessly to Hedera and other EVM ecosystems. Think of it as shared worlds where domain-specific networks stay private by default, interoperate when needed, and run on fully managed, enterprise-grade infrastructure from Hashgraph.
One breakthrough was Hedera's Stablecoin Studio's inaugural commercial implementation via the Australian Digital Dollar (AUDD) launch. It was also the first stablecoin offering institutional-grade fiat on-ramping for Asia-Pacific markets. AUDD opened a corridor between traditional banking infrastructure and public crypto rails, minus the friction for users.
Wyoming Frontier Stable Token (FRNT) selected Hedera as a blockchain candidate for the United States' first state-issued stable token. Bank of England and BIS Innovation Hub DLT Challenge chose Hedera as one of only two L1 networks for exploring the future of money and RTGS synchronization. The Georgia Ministry of Justice MOU began exploring migrating the national real estate registry to Hedera.
In 2025, Hedera developer tools gained recognition when GFM Review awarded the network Best Web3 Developer Tools.
