Hedera: A Public Hashgraph Network and Governing Council
The Hedera whitepaper was co-authored and published by Dr. Leemon Baird and Mance Harmon. The Hashgraph technology whitepaper was released on May 31, 2016, and the Hedera network officially launched its mainnet in 2019. Its aim is to address the limitations of traditional blockchains in performance, security, governance, stability, and regulatory compliance, exploring the construction of a widely adopted public distributed ledger.
The core theme of the Hedera whitepaper is “The Swirlds Hashgraph Consensus Algorithm: Fair, Fast, Byzantine Fault Tolerance.” Hedera’s uniqueness lies in its adoption of the Hashgraph consensus algorithm, a data structure based on a directed acyclic graph (DAG), which achieves asynchronous Byzantine fault tolerance (ABFT) through the “gossip about gossip” protocol and virtual voting mechanism. Hedera’s significance is in providing a high-speed, secure, low-cost, and enterprise-grade distributed ledger solution, laying an efficient and stable foundation for decentralized applications and microservices.
Hedera’s original intention is to build a trustworthy and secure online world, serving as the trust layer of the internet, enabling users and enterprises to interact in a secure and private environment. The core viewpoint in the Hedera whitepaper is: by combining the Hashgraph consensus algorithm with its unique governance model (managed by a global council), Hedera delivers a highly scalable and stable public distributed ledger with high performance, top-level security, and fairness, supporting a wide range of enterprise applications.
Hedera whitepaper summary
What is Hedera
Friends, imagine the internet we use every day as a massive information superhighway. Blockchain technology is like a newly built, safer, and more transparent dedicated lane on that highway. Hedera (HBAR for short) is one such special “dedicated lane,” but it’s a bit different from the “blockchain” we often hear about—it uses a unique technology called Hashgraph.
You can think of Hedera as a “public infrastructure” that provides trust and efficiency for the digital world. It’s not a system controlled by a few people, but one maintained and managed by many well-known enterprises worldwide. Its goal is to enable everyone to quickly, securely, and fairly conduct various digital activities on this platform, such as sending digital currency, creating digital assets (like digital certificates, game items, etc.), running smart contracts (self-executing digital agreements), and storing files.
Simply put, Hedera is like a high-performance digital public ledger. It doesn’t pursue complete anonymity and anti-establishment ideals like Bitcoin, but instead aims to provide the stability, security, and high efficiency required for enterprise-level applications while maintaining decentralization.
Project Vision and Value Proposition
Hedera has an ambitious vision: “to build a trustworthy, secure, and empowering digital future for everyone.” Its mission is to create a trusted and secure online world where everyone can confidently work, play, trade, and socialize, enjoying safety and privacy within digital communities.
Hedera aims to address several core issues faced by current distributed ledger technologies (DLT, such as blockchain) in widespread adoption:
- Insufficient performance: Many traditional blockchains process transactions slowly and have high fees.
- Security challenges: Although blockchain is known for security, there are still risks in certain extreme cases.
- Governance difficulties: How can a decentralized system make effective decisions without being controlled by a few?
- Lack of stability: Some projects may face technical or legal instability.
- Compliance issues: How to meet legal and regulatory requirements in an increasingly strict global environment?
To solve these problems, Hedera stands out. It doesn’t use the traditional “chain” structure but instead adopts the unique Hashgraph technology, which gives it significant advantages in speed, fairness, and security. In addition, Hedera’s governance model is distinctive: it is jointly managed by a council of globally renowned enterprises, providing a stronger foundation of trust and stability for enterprise-level applications and making compliance easier.
Technical Features
The most striking aspect of Hedera is its core technology: instead of traditional blockchain, it uses the Hashgraph consensus algorithm.
Hashgraph Consensus Algorithm
You can imagine traditional blockchain as a train, with each carriage (block) connected in sequence, moving forward one by one. Hashgraph, on the other hand, is more like a “gossip network”:
- “Gossip about Gossip”: Every node (participant) in the network randomly shares the transaction information it knows, as well as information it has heard from others, with other random nodes. Like people chatting, information spreads rapidly throughout the network.
- “Virtual Voting”: Once information has spread sufficiently, each node can independently, without actual voting, use algorithms to “infer” how all nodes would vote, thus reaching consensus on the order of transactions.
This mechanism brings several key advantages:
- High speed and efficiency: Hedera can process tens of thousands of transactions per second (10,000+ TPS), with extremely short confirmation times—almost instant finality. This is much faster than many traditional blockchains.
- Fairness: The Hashgraph algorithm ensures that the order of transactions is fair, and no one can manipulate the sequence—like a fair queuing system.
- Security: It achieves the “gold standard” in distributed system security—asynchronous Byzantine Fault Tolerance (aBFT). This means that even if some nodes in the network are malicious or faulty, the system can still operate normally and reach consensus, without being compromised by attackers.
- Low energy consumption: Unlike blockchains like Bitcoin that require massive computational mining, Hedera’s consensus mechanism does not consume huge amounts of energy, making it more environmentally friendly.
Services Provided by Hedera
Hedera is not just a digital currency network—it offers a variety of services, like a multifunctional digital platform:
- Hedera Consensus Service (HCS): Think of it as a “decentralized message bus,” allowing any application or consortium chain to use the Hedera network to record events, messages, or data, with a trusted timestamp and fair ordering.
- Hedera Token Service (HTS): Enables users to easily create and manage their own digital tokens on the Hedera network, whether fungible tokens (like regular currency) or non-fungible tokens (NFTs, like digital art).
- Hedera Smart Contract Service (HSCS): Supports smart contracts written in Solidity, meaning developers familiar with Ethereum can more easily build applications on Hedera.
- Hedera File Service (HFS): Provides decentralized file storage, allowing files to be securely stored on a distributed network.
It’s worth noting that Hashgraph technology was originally patented, but the Hedera council has voted to purchase the patent rights and open source it, helping to promote broader adoption and ecosystem development.
Tokenomics
The “fuel” of the Hedera network is its native cryptocurrency, called HBAR.
Token Basics
- Token symbol: HBAR
- Total supply: HBAR has a fixed total supply, capped at 50 billion. This means no new HBAR will be minted indefinitely, ensuring scarcity.
- Issuance mechanism and circulation: HBAR is released according to a preset schedule, gradually unlocked rather than entering circulation all at once. Hedera regularly publishes reports detailing HBAR unlocks. As of 2024, about 42 billion HBAR are in circulation.
Token Utility
HBAR plays several important roles in the Hedera network:
- Paying network service fees: Just like you pay for internet access, any operation on the Hedera network—sending transactions, running smart contracts, storing files, or using token services—requires a small amount of HBAR as a fee. These fees are typically very low and predictable.
- Network security and staking: HBAR can also be staked, meaning you lock your HBAR in the network to help maintain its security and consensus. By staking, you contribute to network stability and may earn rewards.
Token Allocation and Unlocking
HBAR’s allocation is carefully designed: a portion is used to incentivize early contributors, including founders and core team members, whose tokens are unlocked in stages to align their interests with the project’s long-term development. Another portion is reserved for community and ecosystem funding, as well as future staking reserves.
Team, Governance, and Funding
Core Team
Hedera’s creation owes much to two key figures:
- Dr. Leemon Baird: Inventor of the Hashgraph consensus algorithm, co-founder and Chief Scientist of Hedera.
- Mance Harmon: The other co-founder of Hedera.
In addition, Hedera has a management team of experienced professionals responsible for daily operations and strategic development.
Governance Mechanism
Hedera’s governance model is unique, adopting a Hedera Governing Council approach.
- Council members: The council consists of leading global enterprises and organizations from various industries and regions, such as Google Cloud, IBM, Deutsche Telekom, etc.
- Decision-making: Each council member has equal voting rights, and their terms are limited, helping prevent any single entity from having excessive control and ensuring diversity and transparency in decision-making.
- Scope of responsibilities: The council is responsible for key decisions regarding the Hedera network, including software updates, network pricing, financial management, and ensuring compliance with evolving regulations.
- Path to decentralization: Hedera is currently a permissioned network, meaning only council members can run nodes. However, the project has a clear plan to gradually transition to permissionless participation, allowing more people to run nodes and achieve broader decentralization. This model aims to balance decentralization with the stability and compliance required for enterprise applications.
Funding
Hedera Foundation is a key driver of Hedera’s ecosystem development. It supports various projects and applications built on the Hedera network through funding, technical support, and community engagement. The foundation’s goal is to raise Hedera’s profile, accelerate innovation, and promote widespread adoption of its technology.
