In a crypto landscape dominated by blockchain-based projects with similar consensus mechanisms, Hedera Hashgraph stands apart. It operates without relying on blockchain technology, instead creating its own network that boasts superior speed and security.
This guide explores Hedera Hashgraph’s fundamentals, how it works, and why it’s gaining attention in decentralized ecosystems.
What Is Hedera Hashgraph?
Hedera Hashgraph is an alternative distributed ledger technology (DLT) platform designed to outperform traditional blockchains in speed, security, and scalability.
Unlike blockchain’s linear block structure, Hedera uses a Directed Acyclic Graph (DAG) framework, where transactions are interlinked like a web. This architecture enables:
- 100,000+ transactions per second (TPS), rivaling payment giants like Visa.
- Average transaction finality in 5 seconds, surpassing Ethereum (1.2M daily transactions) and Bitcoin (300K daily transactions) combined.

How Hedera Hashgraph Works
Hedera leverages two core protocols to achieve consensus:
Gossip About Gossip
- Nodes share transaction data ("gossip") with randomly selected peers.
- Each gossip event includes cryptographic hashes of prior events, creating an auditable, tamper-proof history.
Virtual Voting
- Nodes virtually "vote" on transaction validity without direct communication.
- A transaction is confirmed once 2/3 of the network agrees, ensuring Byzantine fault tolerance.
This dual-mechanism eliminates bottlenecks like mining delays, enabling parallel transaction processing.
Key Services Offered by Hedera
Hedera’s ecosystem supports four primary services:
| Service | Function |
|---|---|
| HBAR Cryptocurrency | Powers low-fee (<$0.01) transactions and network operations. |
| Smart Contracts | Executes decentralized logic using Solidity (Ethereum-compatible). |
| File Storage | Provides distributed, redundant file storage with granular permissions. |
| Consensus Service | Enables fast, secure consensus for third-party apps. |
Hedera vs. Traditional Blockchains
| Feature | Hedera Hashgraph | Traditional Blockchains |
|---|---|---|
| Consensus | Gossip + Virtual Voting | PoW/PoS |
| Speed | Seconds to finality | Minutes (Bitcoin) to hours (Ethereum) |
| Decentralization | Governed by 19 trusted entities | Open participation (e.g., Ethereum) |
