From Blockchain To Hashgraph: The Rise Of Hedera

Hedera Hashgraph: The Sustainable, Scalable & Secure Distributed Ledger

by Kadeem Clarke

A growing number of crypto start-ups are working to improve blockchain technology to be more scalable and accessible.

👀 They have the hope that blockchain can become the infrastructure of the future if it is sufficiently fast.

💪 Cryptos are competing to be the frontrunners in the race.

💭 Hedera was created as a solution to the problems caused by blockchain technology.

Hedera was created as a substitute for developers and users to transact and deploy decentralized applications using public distributed ledger infrastructure.

This distinguishing feature sets it apart from others.

🤔 What is Hedera?

Hedera is a novel public distributed ledger technology model for developing and deploying decentralized applications (dApps) and microservices.

Hedera’s public distributed ledger technology promotes consensus in transaction validity and a decentralized network to ensure confidentiality and fairness.

Hedera is a project built on a chain of blocks and the Directed Acyclic Graph (DAG) technology, which is used for data storage in Hedera as an alternative to traditional blockchain technology.

The Hashgraph consensus-powered Hedera Proof-of-Stake public network achieves the highest level of security, lightning-fast transaction speeds, and low bandwidth consumption.

📜 History of Hedera

Hedera was founded in the United States by Leemon Baird and Mance Harmon.

Baird, based in Dallas, is Hashgraph’s chief scientist and is widely regarded as the inventor of the hashgraph algorithm.

He founded several companies before Hedera (HBAR), including Swirlds Inc and BlueWave Security. He also worked as a senior research scientist at the United States Air Force Academy’s Academy Center for Cyberspace Research, where he earned a BSc in computer science. Baird earned his doctorate in computer science from Carnegie Mellon University.

Mance Harmon, the Hedera cryptocurrency’s CEO, studied computer science at Mississippi State University. Harmon has over two decades of experience founding and leading businesses. He and Baird co-founded BlueWave Security, and Swirlds Inc.

Hedera changed to Hedera Hashgraph, LLC, in 2018. In its token sale, Hedera Hashgraph raised $120 million. The Hedera mainnet went live with 50 billion HBARs in circulation.

  • The first Hedera Governing Council members were announced in 2019.
  • The HBAR token reached an all-time high of $0.5518 on September 15, 2021.
  • Hedera Hashgraph began a partnership with Google for its governing council in 2020.
  • A “governing council” of up to 39 global companies and entities now owns and manages Hedera.

🔗 What is Hashgraph?

The technology behind this novel blockchain is relatively complex.

Hashgraph nodes share information using a “gossip” protocol. This means that news of new transactions spreads quickly and persistently throughout the community.

To share transactions with the community, a data structure is created that contains the payload of those transactions, a timestamp, a digital signature, and two hashes pointing to previous gossip structures.

According to the protocol’s documentation, sharing this information, dubbed “Gossip-to-Gossip,” is unique to the platform. This information trail enables nodes to participate in a virtual voting protocol, which is also unique to the ecosystem. Using the gossip protocol, nodes can quickly exchange information with other nodes in their local virtual community.

The platform claims that previous limitations have been removed due to the development of this new type of blockchain iteration. Hedera claims the proof is in the numbers, as it can process around 10,000tps.

The Hedera cryptocurrency platform’s average fees are also significantly lower. The average fee for Hedera is $0.0001.

Transaction confirmation time is also reduced, with Hedera’s protocol taking only 3 to 5 seconds.

Because it uses a proof-of-stake model rather than proof-of-work, Hedera claims to be much more energy efficient and sustainable than Bitcoin and Ethereum 1.0. Hedera consumes only 0.00003kWh.

⚖️ Blockchain vs. Hashgraph

🤔 Will Hashgraph Replace Blockchain?

Hashgraphs are the key to resolving the current Blockchain development issues. It essentially can turn the economy on its head. 

However, it is a long shot to claim that Blockchain is superior to Hashgraphs. Hedera Hashgraph is still in its infancy in terms of maturity and use cases when compared to Blockchain; thus, it is premature to predict that it will overtake it anytime soon.

The only way to determine whether Hedera Hashgraph is a viable replacement for Blockchain technology is to wait until both systems have matured and all issues have been resolved. After all, only then will the true potential of Blockchain and Hedera Hashgraph be revealed.

However, there are several advantages to using Hashgraph instead of blockchain technology. Blockchain adoption continues to grow, and private blockchains have made it more appealing to businesses.

There are some blockchain issues, but they need to be more significant to make this technology unpopular.

🛠️ Problems Solved by Hedera

Hedera and the Hashgraph are both attempting to solve five problems. Hedera believes addressing these issues can encourage the widespread adoption of distributed ledger technology.

1. Performance

Hedera claims to be extremely fast and can handle more than 10,000 transactions per second, achieving finality in 3-5 seconds.

Hedera testnets have previously achieved a throughput of 50,000 transactions per second. In one test, with only one continent as a constraint, the platform achieved speeds of 500,000 transactions per second.

2. Security

Hashgraph’s consensus algorithm is asynchronous Byzantine Fault Tolerance (aBFT), regarded as one of the most secure methods of consensus.

Hedera’s use of aBFT makes it impossible for any member to break community consensus or change records once consensus has been reached. Less than one-third of the nodes are attackers so that the network can tolerate faulty nodes.

When the network reaches consensus, the community is notified in real-time, ensuring that the consensus cannot be compromised. This means that aBFT protects Hedera from malicious nodes and DDoS attacks even if some network nodes are down or compromised.

3. Governance

Hadera Hashgraph defines two governance models.

The Council Government Model, which we already mentioned, is Hadera’s overall governing body that upholds the network’s decentralization, trustworthiness, and stability.

Each council member may serve up to two consecutive three-year terms.

This configuration allows a single person or organization to utilize more power. The Consensus Model is the second governance model, which allows anyone who wants to run a node to do so.

The consensus model allows anyone to run a node, contribute to consensus, and be rewarded for their efforts. The team anticipates that the number of nodes will rapidly increase, significantly improving the decentralization of Hedera Hashgraph.

4. Stability

Hedera Hashgraph has stated that it will never fork because the platform is kept stable through legal and technical controls that prevent forking.

This prevents the creation of competing platforms, which reduces confusion and uncertainty.

The technical controls create two capabilities. The first is that the software client can always verify the Hashgraph’s pedigree using a shared state mechanism. This shared state consists of all nodes providing verified information and the network’s consensus state.

A bad actor cannot compromise the network in such a shared state, and it also prevents any of the nodes from forking or making changes and then pushing them to the entire network as valid.

The second capability guarantees that any software changes the governing body makes are legitimate because they are automatically updated and specified across the network.

5. Regulatory Compliance

Through an included, optional identity mechanism, Hedera has enabled KYC/AML compliance.

It is known as the Opt-in Escrowed Identity System, and it allows verified identities to be linked to otherwise anonymous wallets.

As governments continue to add regulations to the cryptocurrency landscape, this feature makes it easier for Hedera to achieve mass adoption.

💰 The HBAR Coin

Hedera Hashgraph (HBAR) is the Hedera ecosystem’s native governance token, used to power decentralized applications and protect the network from malicious activity.

Developers use HBAR to power network services such as HBAR transfer, token management (fungible and non-fungible), and data logging.

HBAR token is also used to serve the following utilities:

  • Payment: HBAR token is used to pay transaction fees on the Hedera platform.
  • dApps access: HBAR holders can access dApps released on Hedera.
  • Staking: HBAR token is used for staking and becomes transaction Nodes.
  • Rewards: Users are rewarded with HBAR tokens when participating in the processing of Nodes.

The current CoinMarketCap ranking is #33, with a live market cap of around $2Billion. (as of 14Ap23)

It has a circulating supply of 30.6B HBAR coins and a max. supply of 50M HBAR coins.

🌐 Network Services

Hedera provides four primary services: Token Service, Consensus Service, Smart Contract Service, and File Service. Developers can connect to the network with JavaScript, Java, and Go.

Hedera Token Service (HTS): 

You can configure, mint, and manage native fungible and non-fungible tokens on the Hedera network without deploying expensive and potentially faulty smart contracts.

Hedera Consensus Service (HCS):
