Hedera Hashgraph and HBAR

Hedera Hashgraph And Hbar - Blockchain - Rubix Studios

Hedera Hashgraph is a decentralised public network that allows individuals and businesses to create powerful decentralised applications (DApps). It is designed to be a fairer, more efficient system that eliminates some limitations of older blockchain-based platforms, such as slow performance and instability. This network is powered by Hedera Hashgraph, a unique distributed ledger technology (DLT) that offers a novel approach to achieving decentralised consensus.

Unlike traditional blockchain technologies, Hedera Hashgraph employs a directed acyclic graph (DAG) to provide a secure, fast and fair transaction system. This innovative approach allows for greater speed and security compared to traditional blockchains. HBAR, the native cryptocurrency of the Hedera network, plays a crucial role in its operations, facilitating transactions and incentivising network participation. Together, Hedera and Hedera Hashgraph offer a robust platform for developing and operating scalable, secure and fair decentralised applications.

What is Hedera Hashgraph?

Hedera Hashgraph is a public distributed ledger that provides decentralised consensus through a novel consensus algorithm. Developed by Dr. Leemon Baird, the Hashgraph algorithm is distinct from traditional blockchain technology in several key aspects, including its data structure and consensus mechanism.

How Does Hedera Hashgraph Work?

Hedera Hashgraph operates on a data structure called a directed acyclic graph (DAG), where each node in the network can communicate transaction knowledge to others, leading to a gossip protocol. This results in the rapid dissemination of information across the network. The consensus on transaction order and validity is reached through virtual voting and Byzantine Fault Tolerance (BFT), ensuring the network can function even if some nodes act maliciously.

Key Features of Hedera Hashgraph

  • Speed: Hedera Hashgraph can process thousands of transactions per second (TPS), significantly higher than many traditional blockchain networks.
  • Security: The BFT consensus mechanism ensures high security and resistance to attacks.
  • Fairness: The consensus algorithm provides fair ordering of transactions, minimising the chances of transaction manipulation.
  • Scalability: The network is designed to scale efficiently as more nodes are added, maintaining high performance and low latency.

The HBAR Token

HBAR is the native, energy-efficient cryptocurrency of the public Hedera network. It serves a dual role within the Hedera public network. First and foremost, HBAR is the fuel that powers Hedera services, such as smart contracts, file storage and regular transactions. Second, it’s used to help secure the network since HBAR users can stake their tokens to assist with maintaining the integrity of the platform.

Functions of HBAR

  • Transaction Fees: HBAR is used to pay for transactions and smart contract executions on the Hedera network. The fees are relatively low, making microtransactions feasible.
  • Network Security: Network nodes use HBAR as a stake to ensure security and prevent malicious behaviour. The staking mechanism incentivises nodes to act honestly.
  • Governance: HBAR holders can participate in the governance of the Hedera network, influencing decisions such as software updates and network policies.

HBAR Tokenomics

HBAR has a total fixed supply of 50 billion coins. The distribution of these tokens is managed by the Hedera Governing Council, which oversees the allocation and release of HBAR to ensure the network’s stability and growth.

Network Fuel

Developers use HBARs to pay for network services, such as transferring HBARs, minting fungible and non-fungible tokens, calling smart contracts and logging data. For every transaction submitted to the network, HBARs pay fees that compensate consensus nodes for bandwidth, computing and storage.

Network Protection

Hedera is a public, open-source, proof-of-stake network. When HBARs are staked to network nodes, they have a weighted influence on consensus for processing transactions. Weighted voting makes it difficult and expensive for a bad actor to affect consensus maliciously — it would require a centralised authority to own and stake over one-third of the network’s total supply of HBAR.

Hedera’s Performance

The Hedera proof-of-stake public network, powered by Hashgraph consensus, achieves the highest security grade possible (ABFT) with blazing-fast transaction speeds and incredibly low bandwidth consumption. By combining high throughput, low fees and finality in seconds, Hedera leads the way for the future of public ledgers.

Here’s a comparison of Hedera with the first and second-generation blockchain technologies:

Transactions per second (TPS)

High Throughput

10,000+ Transactions per Second (TPS): Hedera’s high throughput allows it to process a vast number of transactions simultaneously. This scalability is essential for a payment system, as it can handle peak transaction volumes without bottlenecks, ensuring smooth operation even during high-demand periods.

Low Transaction Fees

$0.001 USD per Transaction: Hedera’s minimal transaction fees make It an economically attractive option for consumers and businesses. Low fees reduce the cost of transactions, which is particularly beneficial for microtransactions, small businesses and large enterprises processing numerous transactions.

Quick Transaction Confirmation

3-7 Seconds with Finality: Hedera offers near-instant transaction confirmation times. This rapid finality improves the user experience by providing immediate assurance that payments have been completed, which is crucial for retail transactions, online payments and other time-sensitive financial activities.

Energy Efficiency

0.003 Wh per Transaction: Hedera’s low energy consumption per transaction makes it an environmentally sustainable option. In a world increasingly focused on reducing carbon footprints, this energy efficiency is a significant advantage over more energy-intensive alternatives like Bitcoin.

Governance and Decentralisation

Hedera Governing Council

The Hedera network is governed by the Hedera Governing Council, composed of up to 39 term-limited organisations and enterprises from diverse industries and geographies. These council members are responsible for the strategic direction and decisions regarding the network’s software and operations. The governance model aims to be decentralised and representative, preventing any single entity from gaining undue control over the network.

Council Members

Council members include leading global companies and institutions, such as Google, IBM, Boeing, Deutsche Telekom and University College London. These members contribute to the network’s credibility and decentralisation.

Use Cases and Applications
