Enter Hedera Hashgraph, an innovative solution aiming to address these limitations. This distributed ledger technology (DLT) platform boasts impressive speed, enhanced security, and efficient transaction processing. 

Hedera Hashgraph represents a paradigm shift in distributed ledger technology. It provides a faster, more secure, and more efficient alternative to traditional blockchains. Throughout this blog post, we’ll delve deeper into the inner workings of Hedera Hashgraph, explore its unique features, and showcase its potential applications across a diverse range of industries.

Introduction to Hedera Hashgraph

Hedera Hashgraph is not just another blockchain; it is a public distributed ledger technology platform built on a revolutionary consensus mechanism called Hashgraph.

It’s a platform that facilitates secure transactions, but instead of relying on the traditional blockchain method, it uses a completely different approach called Hashgraph. Transactions on Hedera Hashgraph are lightning-fast, zipping through the system in near real-time. 

Additionally, the unique design called “Byzantine Fault Tolerance” prioritizes security, making it a trusted platform for even the most sensitive information. Hedera Hashgraph achieves its speed and efficiency through innovative techniques like “virtual voting” and “gossip about gossip.” 

Traditional blockchain systems require a lot of energy to operate. Hedera Hashgraph, on the other hand, is incredibly energy-efficient, using a fraction of the power needed by blockchain. This makes it a much greener and more sustainable option for the future.

Key differences between Hedera and Blockchain

Here’s a breakdown of the key differences between Hedera and blockchain, focusing on the core aspects that set them apart:

Consensus Mechanism

Most blockchains rely on validation methods like Proof-of-Work (PoW) or Proof-of-Stake (PoS). These involve miners or validators competing to solve puzzles or stake tokens, respectively, to get the right to add a block to the chain.

Hedera employs the hashgraph consensus algorithm. Nodes “gossip” about transactions with each other, achieving rapid consensus on the order and validity of events, enhanced by the ‘virtual voting’ mechanism.

Data Structure

A blockchain is visualized as a linear chain of blocks, each block containing a batch of transactions.

Transactions in Hedera are arranged in a directed acyclic graph (DAG). Transactions branch out, enabling parallel processing rather than being bundled linearly into blocks.

Speed and Efficiency

Blockchain throughput (transactions per second) and transaction finality (confirmation time) can be limited in some popular blockchains, particularly those using Proof-of-Work.

Hedera Hashgraph’s design enables significantly faster transaction throughput (potentially thousands per second) and near-instant finality.


Many blockchains strive for a fully decentralized governance model, where token holders or network participants vote on protocol changes or key decisions.

Hedera currently operates under a governing council comprising global organizations. Their roadmap includes plans to decentralize governance progressively over time.

Understanding Hedera Hashgraph Properties

Hedera Hashgraph boasts several key properties that set it apart from traditional blockchain technology. Here are some of the most important ones:

Faster Throughput

Hedera Hashgraph processes transactions significantly faster than traditional blockchains. Unlike blockchains that validate transactions one block at a time, Hashgraph utilizes a parallel processing approach, significantly reducing transaction times.

Asynchronous Byzantine Fault Tolerance (aBFT)

Hedera Hashgraph employs a robust security mechanism called Asynchronous Byzantine Fault Tolerance (aBFT). This ensures the network can reach an agreement on the order of transactions even if some nodes malfunction or become unavailable. This guarantees data integrity and protects against malicious actors trying to disrupt the network.


Hedera Hashgraph promotes fairness. Unlike some blockchains, all nodes in the Hedera network have an equal opportunity to participate in consensus. This ensures transactions are ordered in a just and unbiased manner, preventing any single entity from dominating the network.

Low Energy Consumption

Hedera Hashgraph operates with a significantly lower energy footprint compared to traditional blockchains that rely on energy-intensive proof-of-work mechanisms. It’s a more sustainable choice for the future.


The Hashgraph architecture is designed to handle a high volume of transactions efficiently. As the network advances and more users join, its processing power automatically scales to meet the demand. This ensures smooth operation even during periods of high activity.

How Does Hedera Hashgraph Work?

Hedera Hashgraph’s innovative approach relies on two key protocols: Gossip about Gossip and Virtual Voting. Let’s delve into how these protocols work together to achieve faster, more secure, and more efficient transactions compared to traditional blockchains.

Gossip about Gossip

In the world of distributed networks, information dissemination is crucial. Hedera Hashgraph tackles this challenge with a unique concept called “gossip about gossip.” It goes beyond traditional gossiping, where information travels from one node to another. Here’s how it works:

Targeted Sharing

Each node acts like a social butterfly but with a twist. Instead of broadcasting transactions to everyone, they share them with a select group of trusted peers, similar to whispering information to close friends. This reduces network congestion and ensures faster propagation of important transactions.

Building a Chain of Trust

Every piece of gossip carries more than just the transaction itself. It also includes hashes of the last two gossip events the node participated in. Think of these hashes like digital fingerprints, creating a verifiable chain of information. This allows nodes to track the history of received gossip and identify any inconsistencies, preventing the spread of misinformation.


Imagine a network with four nodes: Ana(A), Beth(B), Cloe(C), and Dean(D).

  1. Initiating the Conversation: Beth initiates the gossip by sharing all the events with Dean that Dean might not be aware of.
  2. Adding to the Story: Dean acknowledges the received information and creates a new event, building upon the existing chain. This new event references the two gossip events it originated from using the embedded hashes.
  3. The Cycle Continues: Now, let’s say Dean decides to return the favor and gossip with Beth again. Beth, having already received events from Dean previously, now has a more comprehensive picture.

Over time, as nodes continue to gossip about gossip, the information propagates throughout the network. The embedded timestamps within each gossip message act as timestamps for the transactions. By analyzing these timestamps and the gossip chain, the system can automatically determine the order in which transactions occurred, paving the way for secure and efficient consensus.

Virtual Voting

Nodes in a Hedera Hashgraph network don’t simply accept gossiped transactions. They play an active role in ensuring data integrity and preventing malicious actors through two crucial actions:


Nodes assign a unique timestamp to each transaction, creating a verifiable record of the exact time it was received. This establishes a consistent timeline across the network, which is crucial for accurately ordering transactions.

Virtual Voting

Based on pre-defined rules and the information received, each node casts a virtual “vote” on the validity of the transaction. This vote considers the transaction itself, the trustworthiness of the source node (determined by analyzing gossip history), and the timestamps.
