Definition
Hedera is an enterprise-grade public distributed ledger network governed by a council of global corporations and built on a novel consensus algorithm called Hashgraph– a directed acyclic graph (DAG)-based consensus mechanism that achieves Byzantine Fault Tolerant (BFT) finality in 3–5 seconds with extremely low, predictable fees ($0.0001 per transaction). Founded in 2017 by Dr Leemon Baird (the inventor of Hashgraph) and Mance Harmon in 2018, Hedera is structured as a public benefit LLC governed by the Hedera Governing Council– a consortium of up to 39 global enterprises (approximately 32 current members) including Google, IBM, Boeing, Deutsche Telekom, Ubisoft, Standard Bank, and other Fortune 500 companies. This council-based governance model is intentionally different from most blockchains: instead of open validator permissioning, Hedera uses trusted, known entities to run nodes – trading decentralisation for enterprise-grade reliability, legal accountability, and regulatory compliance. Hedera provides four services: cryptocurrency transfers (HBAR), smart contracts (EVM-compatible), token service (native token creation without smart contracts), and consensus service (verifiable timestamping for any application). HBAR is the network’s native token used for transaction fees and staking.

“Hedera combines the security and trust of blockchain with the speed and efficiency businesses actually need.”
How It Works
| Component | Description |
| Hashgraph | DAG-based consensus; virtual voting; no miners/heavy validators |
| Governing Council | 39 global corporations governing Hedera |
| HBAR Token | Gas fees, staking; 50B total supply |
| Hedera Token Service | Create native fungible/NFT tokens without smart contracts |
| Hedera Smart Contract | EVM-compatible contracts; Solidity supported |
| Hedera Consensus Service | Verifiable, timestamped message log for any application |
| Hedera File Service | Immutable file storage on Hedera network |
| Treasury | Hedera Council controls token treasury and distribution |
In Simple Terms
- DAG not chain: Instead of linking blocks in a chain, Hashgraph creates a web of connected events – more efficient consensus without wasting computation on competing block proposals.
- Virtual voting: Validators don’t actually send vote messages to each other (wasteful). Instead, each validator independently calculates what the consensus result should be by analysing the event gossip graph – reaching the same conclusion mathematically.
- Enterprise governance: 39 Fortune 500 companies govern Hedera – they’re legally accountable, known entities, and regulated in multiple jurisdictions. This gives enterprises confidence that the network won’t suddenly change rules or have key person risk.
- Predictable fees: Unlike Ethereum or Solana where fees fluctuate with demand, Hedera’s fees are fixed in USD terms ($0.0001 per crypto transfer, $0.05 per smart contract) – making enterprise budgeting straightforward.
- Multiple services: Beyond cryptocurrency transfers, Hedera offers a native token service (faster than smart contracts for tokens), consensus service (timestamped logs for any data), and file service – a one-stop blockchain platform.
Real-World Examples
| Scenario | Implementation | Outcome |
| Supply chain tracking | ServiceNow uses Hedera Consensus Service for supply chain logs | Verifiable, immutable timestamps at $0.0001 each |
| Carbon credits | DOVU platform tokenises carbon offsets on Hedera | Transparent, low-cost carbon credit marketplace |
| Loyalty points | Coupon/loyalty platform migrates to Hedera Token Service | 10M+ token transfers at sub-cent fees; no smart contract needed |
| Financial services | Standard Bank explores Hedera for trade finance | Regulatory-compliant, enterprise-grade settlement infrastructure |
Advantages
| Advantage | Detail |
| Fast finality | 3–5 second BFT finality; suitable for payments |
| Predictable fees | Fixed USD-denominated fees; enterprise planning possible |
| Enterprise governance | 39 trusted corporations; legal accountability |
| Energy efficient | No PoW mining; minimal computation; very low energy use |
| Token service | Create tokens without smart contracts; faster and cheaper |
| Regulatory compliance | Known node operators facilitate compliance conversations |
Disadvantages & Risks
| Risk | Detail |
| Centralisation | 39 council nodes initially; not decentralised like Ethereum/Bitcoin |
| Hashgraph patent | Patented technology; only Hedera can use it commercially |
| HBAR supply concerns | Large treasury; council controls significant HBAR supply |
| Limited DeFi | Smaller DeFi ecosystem than Ethereum, Solana, BNB Chain |
| Developer adoption | Less developer tooling and community than major chains |
| Permissioned node model | Community staking/node running still limited compared to open chains |
Risk Management Tips:
- Understand that Hedera’s centralised governance is a feature for enterprise use but a risk for decentralisation purists
- HBAR’s price is partly determined by council token distribution decisions; monitor treasury releases
- Enterprise integrations on Hedera carry execution risk – not all announced partnerships lead to production use
FAQ
What makes Hashgraph different from blockchain?
Traditional blockchains form a single chain of blocks; Hashgraph creates a DAG (directed acyclic graph) of events. Consensus uses “virtual voting” – mathematically calculating agreement from the gossip pattern rather than sending actual vote messages. This allows 3–5 second finality with minimal communication overhead.
Is Hedera truly decentralised?
Hedera is partially decentralised – the ledger itself is permissionless for transactions, but node operation is currently restricted to the 39 Governing Council members. Hedera plans to expand permissioned staking over time, but it remains more centralised than Ethereum or Solana.
Who are the Hedera Governing Council members?
Members include Google, IBM, Boeing, Deutsche Telekom, Ubisoft, Standard Bank, LG Electronics, Shinhan Bank, and 31 other global enterprises across technology, finance, healthcare, and other industries. Each serves a 3-year renewable term.
Can I run a Hedera node?
Currently, only Governing Council members run consensus nodes. Community nodes for mirror/archive functions are available. Hedera has indicated plans to open node participation more broadly over time.
What is the total HBAR supply?
HBAR has a fixed supply of 50 billion tokens. A significant portion remains in the Hedera treasury (council-controlled) and is released over time to fund ecosystem development and reward contributors.
