Hedera (HBAR) คืออะไร

Hedera Hashgraph is a public distributed ledger technology founded in 2018 by Dr. Leemon Baird and Mance Harmon. Unlike traditional blockchains, it utilizes a unique consensus algorithm called Hashgraph, which employs a directed acyclic graph structure to achieve high throughput, low latency, and fair ordering of transactions. The network was designed to address the scalability and security limitations of first-generation blockchain systems.

The governing body behind Hedera is the Hedera Governing Council, composed of leading global organizations across various industries, including Google, IBM, Boeing, and Deutsche Telekom. This council ensures decentralized governance and network stability, distinguishing Hedera from many other crypto projects that rely on informal community governance or single-entity control.

HBAR is the native cryptocurrency of the Hedera network. It serves two primary functions: securing the network through staking and paying for transaction fees. Fees are fixed in USD terms but paid in HBAR, providing predictability for enterprises building decentralized applications. Since its mainnet launch in August 2019, Hedera has focused on enterprise-grade solutions, emphasizing compliance, sustainability, and high performance for use cases like supply chain tracking, tokenization, and decentralized finance.

Hedera Hashgraph was co-founded by Dr. Leemon Baird and Mance Harmon. Dr. Baird, a computer scientist with a PhD from Brigham Young University, invented the hashgraph consensus algorithm that powers the Hedera network. Mance Harmon, an experienced entrepreneur and software engineer, partnered with Baird to bring this technology to market. They established Hedera in 2018 with the goal of creating a public network that offers high throughput, low latency, and fair ordering of transactions without the energy inefficiencies associated with traditional proof-of-work blockchains.

The project is governed by the Hedera Governing Council, which initially included major global enterprises such as Google, IBM, Boeing, Deutsche Telekom, and LG Electronics. This unique governance model was designed to ensure stability, compliance, and decentralized decision-making among trusted industry leaders. While Baird and Harmon are the original creators, the ongoing development and maintenance of the Hedera network are managed by Hedera Hashgraph LLC and supported by the broader community and council members. The native cryptocurrency of the network is called HBAR, which is used to pay for transaction fees and secure the network through staking.

Hedera Hashgraph operates on a unique distributed ledger technology known as the hashgraph consensus algorithm, which differs significantly from traditional blockchain structures. Instead of organizing transactions into linear blocks, Hedera uses a directed acyclic graph structure. This allows for high throughput, low latency, and fair ordering of transactions. The network is governed by a council of leading global organizations, ensuring decentralized decision-making and stability.

At its core, the system relies on a gossip-about-gossip protocol. Nodes continuously share information about transactions they have received, including metadata about previous communications. This enables each node to independently calculate the consensus timestamp and order of events without needing to communicate further. The result is asynchronous Byzantine Fault Tolerance, providing maximum security even if some nodes act maliciously.

The native cryptocurrency, HBAR, serves two primary functions within the ecosystem. First, it is used to pay for transaction fees and smart contract executions on the network. These fees are fixed in USD terms but paid in HBAR, protecting users from volatility during transactions. Second, HBAR is essential for network security through staking. Token holders can stake their HBAR to specific nodes, influencing the weight of those nodes in the consensus process. This mechanism aligns incentives, encouraging honest behavior and maintaining the integrity of the ledger while supporting fast and efficient decentralized applications.

Hedera Hashgraph distinguishes itself from traditional blockchain networks by utilizing a Directed Acyclic Graph (DAG) structure known as the hashgraph consensus algorithm. This innovative approach allows for high throughput, low latency, and fair ordering of transactions without the need for energy-intensive mining. The network is governed by a council of prominent global organizations, ensuring decentralized decision-making and long-term stability. A core feature is its asynchronous Byzantine Fault Tolerance (aBFT), which provides the highest possible level of security guarantee for distributed systems. This means the network can reach consensus even if some nodes fail or act maliciously, ensuring data integrity and trustlessness. Hedera also offers predictable and extremely low fees, typically fractions of a cent, making it highly scalable for enterprise-grade applications and micropayments. The native cryptocurrency, HBAR, serves two primary purposes: securing the network through staking and paying for transaction fees and smart contract executions. Unlike proof-of-work systems, Hedera is environmentally sustainable, consuming significantly less energy per transaction. Its architecture supports three main services: Cryptocurrency for token transfers, Consensus Service for timestamping data, and Smart Contract Service for deploying decentralized applications. These features collectively position Hedera as a robust public ledger designed for the next generation of decentralized infrastructure.

Hedera Hashgraph utilizes a transparent and structured token distribution model for its native cryptocurrency, HBAR. The total supply is capped at 50 billion tokens. A significant portion of the initial supply was allocated to early contributors, including founders, advisors, and key partners, subject to vesting schedules to ensure long-term alignment with the network's success. The Hedera Treasury holds a substantial reserve of HBAR, which is strategically released to fund ecosystem growth, developer grants, marketing initiatives, and operational expenses. This treasury management is overseen by the Hedera Council, ensuring responsible stewardship. Community sales and public offerings have also played a role in distributing tokens to a broader investor base, promoting decentralization. Staking rewards are distributed to node operators and stakers who secure the network, incentivizing participation and maintaining consensus integrity. The distribution mechanism aims to balance immediate liquidity needs with long-term sustainability, preventing excessive inflation while supporting network expansion. Regular transparency reports are published to detail treasury movements and token circulation metrics. This approach fosters trust among stakeholders by providing clear visibility into how tokens are allocated and released over time. The vesting periods for early investors help mitigate market volatility by preventing sudden large-scale sell-offs. As the network matures, the focus shifts towards community-driven governance and decentralized control, reducing reliance on central entities for token management. Understanding these dynamics is crucial for investors assessing the long-term value proposition of HBAR within the distributed ledger technology landscape.

Hedera Hashgraph serves as a decentralized public network designed for the next generation of economy, enabling fast, fair, and secure transactions. Its native cryptocurrency, HBAR, plays a critical role in securing the network and facilitating various applications. The primary use of HBAR is to pay for transaction fees and smart contract services on the Hedera network. Unlike traditional blockchains that rely on mining or staking for consensus, Hedera uses a unique hashgraph consensus algorithm, which allows for high throughput and low latency.

In terms of application scenarios, Hedera is widely adopted in enterprise solutions due to its compliance-friendly features and predictable pricing. One major sector is supply chain management, where companies use Hedera to track goods from origin to destination, ensuring transparency and reducing fraud. For instance, global brands utilize the network to verify the authenticity of products, providing consumers with immutable proof of provenance.

Another significant area is decentralized finance (DeFi). Developers build financial applications on Hedera that benefit from its high speed and low costs. This includes tokenization of real-world assets, such as real estate or commodities, allowing for fractional ownership and easier trading. Additionally, Hedera supports identity management solutions, enabling secure and private digital identities for individuals and organizations, which is crucial for KYC and AML compliance in regulated industries.

The network also powers micropayments and content monetization models. Creators can receive instant payments for their work without intermediaries taking large cuts, thanks to HBAR's low transaction fees. Furthermore, Hedera is used in energy trading, facilitating peer-to-peer energy exchanges between producers and consumers, promoting sustainable practices. Overall, HBAR acts as the fuel for these diverse ecosystems, ensuring network security through its proof-of-stake mechanism while enabling innovative use cases across multiple industries.
