Hedera represents one of the most intriguing advancements in cryptocurrency, revealing greater potential the deeper you explore it. This guide provides a concise overview of the Hedera network, its native cryptocurrency HBAR, and how hashgraph technology differs from traditional blockchain.
What is Hedera (HBAR)?
Hedera (HBAR) is a distributed ledger technology based on hashgraph, a consensus algorithm where users agree on transaction order. Unlike blockchain, hashgraph boasts 100% efficiency—no transactions are discarded, and all branches are stitched into a unified whole.
Key Differences Between Hedera and Blockchains:
- Efficiency: Hashgraph uses all transaction data, eliminating wasted cycles.
- Finality: Hedera achieves Asynchronous Byzantine Fault Tolerance (ABFT), ensuring transactions are finalized in seconds.
- Gossip Protocol: Employs "gossip about gossip" for rapid, energy-efficient consensus.

How Does Hedera’s Hashgraph Work?
The "Gossip About Gossip" Protocol
Dr. Leemon Baird, Hedera’s inventor, describes gossip as nodes randomly sharing unknown information. This method is:
- Fast: Spreads like a rumor.
- Energy-Efficient: Uses minimal bandwidth.
Each message includes:
- Cryptographic hashes of two prior messages.
- A list of transactions.
This creates a secure, transparent ledger for HBAR transactions.
Who Created Hedera?
- Founder: Dr. Leemon Baird (PhD, Carnegie Mellon), a computer scientist with 20+ years in startups and academia.
- Governing Council: Includes Boeing, Google, IBM, and The London School of Economics.
- Use Cases: England’s NHS used Hedera for COVID vaccine records, highlighting its trustworthiness.
