What is Hedera Hashgraph (HBAR)? A Comprehensive Guide to the Future of Decentralized Technology

What is Hedera Hashgraph (HBAR)?

In today’s digital age, the concepts of decentralized technologies and blockchain are frequently heard. While pioneers like Bitcoin and Ethereum have raised awareness in this field, the challenges of scalability, security, and speed that these technologies face have paved the way for new innovations.

This is where Hedera Hashgraph (HBAR), with its distinct approach from traditional blockchain architecture, stands out. In this article, we will delve into what Hedera Hashgraph is, the key features that set it apart from other cryptocurrencies and blockchain platforms, its operational principles, and its future potential.

The Genesis of Hedera Hashgraph: Why a Different Approach Was Needed

While blockchain technology offers a revolutionary solution for securely and transparently recording digital transactions, it grapples with some fundamental challenges:

Scalability: Blockchain networks are limited in the number of transactions they can process per second (TPS). Bitcoin can handle an average of 7 transactions per second, and Ethereum 15-30, whereas traditional payment systems like Visa can process tens of thousands of transactions simultaneously. This poses a major barrier to the mainstream integration of blockchain.
Security: Although blockchain has a secure structure, the complexity and potential vulnerabilities of its consensus mechanisms, such as the energy spent on transaction approval (Proof of Work) or stake ratio (Proof of Stake), have drawn criticism.
Speed and Latency: It can take a long time for a transaction to be added to and confirmed by the network, making it unsuitable for applications like instant payments.

Hedera Hashgraph offers a solution to these problems not with a blockchain, but with a different type of Distributed Ledger Technology (DLT) architecture called Hashgraph. The Hashgraph is fundamentally different from the block-chaining structure of blockchain. Instead of grouping transactions in a single linear chain, it records interconnected events in a tree-like structure, or more accurately, a Directed Acyclic Graph (DAG).

How Hashgraph Works: An Advanced DLT Architecture

At the heart of Hedera Hashgraph lie two core mechanisms that ensure the network’s incredible speed, security, and efficiency: the Gossip Protocol and Virtual Voting.

1. The Gossip Protocol

In a blockchain, when new blocks are created, all nodes in the network must synchronize with that block. This process is time-consuming and increases network traffic. In Hedera, this is handled by a more efficient protocol known as “gossip about gossip.”

Each node receives information (transaction data, events) from a randomly chosen node in the network and forwards this information to another random node.
During this information transfer, each node also adds its own events to the newly created event. These events include the node’s own transactions and those it has learned from other nodes.
This process, much like a piece of gossip, spreads through the network very quickly. By constantly propagating the information, each node ensures the entire network is synchronized in a very short time. This means every node has a full copy of all transactions.

2. Virtual Voting

In a blockchain, to achieve final confirmation of a transaction, all nodes (or a large portion of them) must physically vote using a consensus mechanism (PoW, PoS). This slows down the transaction speed.

Hedera’s virtual voting mechanism, however, makes this process virtual:

Thanks to the gossip protocol, every node has a complete history and order of all transactions in the network.
Based on this history, they can virtually determine what all other nodes would have voted for regarding the validity and order of a transaction. There’s no need for a physical vote.
If a consensus has been reached on a transaction (e.g., more than two-thirds of the network are in agreement), that transaction is considered confirmed instantly.
This mechanism eliminates the waiting time for physical voting, thereby increasing both speed and energy efficiency.

The combination of these two mechanisms allows Hedera Hashgraph to process tens of thousands of transactions per second (10,000+ TPS) with an almost instant latency (3-5 seconds). This is a monumental improvement over traditional blockchain networks.

The Key Features That Make Hedera Unique

Hedera Hashgraph stands out not only for its speed and scalability but also for its unique features:

Proven Asynchronous Byzantine Fault Tolerance (aBFT): Hedera provides one of the highest levels of security ever achieved, aBFT. This means that as long as a malicious attacker does not control more than one-third of the network, the network will continue to operate, and the security of transactions is guaranteed. Networks like Bitcoin and Ethereum cannot fully achieve Byzantine Fault Tolerance.
Governing Council: While Hedera has a decentralized structure, it is governed by a Governing Council of global corporations that determine the network’s strategic direction. With giants like Google, Boeing, IBM, LG, and Dell on board, this council aims to accelerate Hedera’s corporate adoption and ensure the network’s stable growth. While this structure is criticized by some advocates of complete decentralization, it offers significant assurance for corporate and regulated sectors.
Low, Fixed Transaction Fees: Hedera’s transaction fees do not fluctuate based on network traffic. It offers fixed and very low-cost transactions. This is a huge advantage, especially for micro-payments and corporate applications. For instance, a transaction fee can be as low as an average of $0.0001.
Smart Contracts and Token Services: Hedera supports Ethereum-compatible smart contracts (Solidity) and enables developers to create their own decentralized applications (dApps). Furthermore, with Hedera Token Service (HTS), users can efficiently and easily create their own cryptocurrencies or tokens.
File Service: The network also provides a file service to store files securely. This is an important feature, particularly for corporate applications that need to maintain data integrity.

The Role and Economics of the HBAR Token

The native cryptocurrency of the Hedera network is HBAR. HBAR plays a vital role in the network’s operation:

Payment for Network Transactions: Users pay with HBAR to make transactions, run smart contracts, or upload files on the Hedera network. This creates a continuous demand for the token.
Securing the Network (Proof of Stake): HBAR can be staked to secure the network using a Proof of Stake mechanism. HBAR holders can contribute to the network’s security by delegating their HBAR to nodes and earning rewards in return. This incentivizes token holders to stay committed to the network.

The circulation of HBAR is not inflationary, as the total supply is capped at 50 billion HBAR. This limited supply can help HBAR maintain its value in the long run.

Use Cases and Potential of Hedera Hashgraph

Hedera’s high speed, low cost, and enterprise-friendly structure make it a potential solution in many different sectors:

Finance and Payments: International payments, micro-payments, and the tokenization of financial assets.
Supply Chain Management: Tracking products, preventing counterfeiting, and creating a transparent supply chain.
Healthcare: Securely sharing and managing patient data.
Gaming and Entertainment: Trading NFTs (Non-Fungible Tokens) and in-game assets.
Internet of Things (IoT): Enabling billions of devices to communicate with each other securely and at a low cost.

The presence of major corporations on the Governing Council significantly increases Hedera’s potential to move beyond a theoretical project and be integrated into real-world applications. By eliminating the disadvantages of blockchain, such as slowness and high costs, Hedera aims to provide an ideal infrastructure for the decentralized applications of the future.
