The Hashgraph vs Blockchain debate has been a burning issue in the tech world. Both technologies offer excellent solutions to common problems with older distributed ledgers. Let us compare and contrast Hashgraph and Blockchain, looking at their advantages and disadvantages.


Definition of Hashgraph and Blockchain

Hashgraph is an innovative data structure that utilizes an aBFT consensus mechanism. This allows users to securely and quickly agree on the state of digital ledgers without relying on third parties. It promises speed, fairness, trustlessness, and security.

In contrast, blockchain is a type of DLT. It uses blocks of data connected by cryptographic linking, or hashing. This creates records like transactions or other files like images and text documents. Every block is linked chronologically, so you can trace back the history of every piece of info in the entire network. This immutability is why blockchain is so trusted for storing records digitally.


Key Differences

Two new technologies, Hashgraph and Blockchain, are shaking up the digital world. Both offer advantages over old methods of data transfer. What’s the difference between the two? Here we compare and contrast Hashgraph and Blockchain, revealing their key differences.


Consensus Mechanisms

Two main consensus mechanisms for distributed ledger technology are blockchain and hashgraph. Both share resemblances, yet have important distinctions, making them suitable for diverse projects depending on their requirements and desired results.

Blockchain uses blocks of transactions that are added to an existing chain. All transactions are visible, thus eliminating the need for third-parties. Computers must work together, using a consensus mechanism called Proof-of-Work, to add and validate new blocks.

Hashgraph has an alternate consensus mechanism to PoW. It randomly picks two nodes from the network to take part in achieving consensus. This is done through voting rounds, whereby the nodes either accept or reject each record. This is called Gossip Protocol or Virtual Voting. It is quicker than PoW and uses less energy, making it a sustainable solution for certain applications.



Blockchain and Hashgraph differ drastically when it comes to security. Blockchain depends on multiple nodes storing and confirming a single ledger. If one node is breached, it can cause false data to be shared.

Hashgraph utilizes consensus protocols and virtual voting to decide which transactions are accepted. Even if a node is compromised, the attacker can’t take control of the system as they must have more than 50% of nodes to make malicious changes. Plus, aBFT allows validators in any location or latency class to securely participate in consensus. This provides a safe way to verify and approve transactions.



Hashgraph and blockchain differ in speed evaluation. Hashgraph has been designed to be faster, by orders of magnitude. It has a faster consensus algorithm and improved way to handle data transactions. This brings down transaction times.

Traditional blockchains have limited scalability. This can cause saturation if not managed correctly. This may lead to backlogging and delays due to the limitation on the number of transactions per second.

Since 2016, numerous tests and experiments have shown that hashgraph technology can process hundreds of thousands of transactions per second. This is much more than conventional blockchains can offer, so end users benefit from increased speeds. Furthermore, hashgraph is more secure than blockchain, making it suitable for use cases which need fast speeds and secure data storage.



Hashgraph technology is more cost effective than blockchain. It does not need validation from miners, like blockchain does. Transactions then occur faster, allowing for higher throughput. There are also fewer overhead costs with hashgraph, since there are no miners needed.

Blockchain, however, needs validation from miners before transactions can be processed. This means transactions can take longer, and there are usually higher overhead expenses to pay miners.

Both technologies have advantages concerning security, transparency and anonymity; however, hashgraph technology has a lower cost solution that can offer similar benefits to blockchain, but without some of its drawbacks.



Hashgraph and Blockchain have both been used in several industries. Hashgraph is a Distributed Ledger Technology (DLT) which ensures secure and legitimate digital transactions. It can be used for financial or healthcare data storage and management.

Blockchain is another DLT form which has found application in digital currencies. Additionally, it has been implemented in healthcare, finance, and governmental sectors.

This section covers the applications of both Hashgraph and Blockchain.


Financial Services

Financial services are one of the most popular areas that use distributed ledger technology to create efficiency, speed and security. Comparing hashgraph vs blockchain is essential to know which ledger fits the need.

Hashgraph and blockchain both record and store data. But their approaches vary. Hashgraph tech provides higher speed, scalability and throughput due to its novel consensus algo, gossip protocol and virtual voting. This allows it to handle more transactions per second than blockchains.

Blockchain tech has a consensus mech that does not use virtual voting concepts such as PoW, allowing fewer TPS throughputs when it comes to recording transactions.

The benefits of using either technology for financial services depend on transaction speed, scalability, privacy needs and data immutability requirements.

For example, if low payments require high levels of confidentiality, then blockchain tech works best. Its immutability ensures records can’t be tampered with. But if rapid processing times are needed then hashgraph is the way to go. It provides faster order execution times due to increased transaction speeds. Plus, it offers permissions based sharing models unlike blockchains which have public or open access systems.



The healthcare industry is a great place to use blockchain and hashgraph technology. It can give secure and reliable ways to store medical records. Hashgraph has the power to make processing faster, especially with large volumes of data. Blockchain technology can prevent wrong or malicious modifications to patient data.

Hashgraph can make patient record-keeping easier, with real-time updates across multiple healthcare providers. It can also store large amounts of data without any issues. Plus, using a decentralized system reduces the need for hospital/healthcare IT resources to process and maintain patient records. All this is possible thanks to the shared task of a distributed ledger system.


Supply Chain

Supply chain management is a key element of the global economy. Businesses are on the hunt for ways to move their products from raw materials to finished goods securely and efficiently. Blockchain and Hashgraph technologies offer innovative solutions to create an unchangeable record at every step. This helps stakeholders to make knowledgeable choices quickly.

Blockchain tech was created to store data on a spread-out ledger safely. Agencies all over the world can store and access shared data without being in charge of its maintenance or dependability. Transactions are added as blocks, creating a secure chain that can be accessed by those who have authorization. This tech can be used in various sectors, particularly supply chain management, enabling companies to monitor stock levels and audit trail of action along the whole supply chain.

Hashgraph is another shared ledger platform. It allows organizations to securely track and process transactions within supply chains, using digital signatures and consensus algorithms that authenticate the identity of participants in each transaction. Hashgraph uses directed acyclic graph (DAG) data structures, allowing it to process more than 100,000 transactions per second without compromising security or privacy. Compared to blockchain, it offers better scalability, so it’s great for big companies where security and dependability are necessary when dealing with millions of assets across many countries all at once.



It’s obvious that deciding between blockchain or hashgraph tech depends on the business’ needs. Blockchain is a well-known industry stand, with lots of features. Hashgraph offers something different, with faster transactions and added security.

To choose which works best for a project or org, it’s important to consider each system’s pros and cons. Hashgraph has many unique benefits, like scalability and reliability. Blockchain systems make permanent records, verified by distributed consensus models. Organizations should decide which technology they need, based on their goals and resources.
