Blockchain vs. Hashgraph vs. Dag vs. Holochain: 4 Types of DLTs

Reading Time: 6 minutes

Bitcoin is a digital currency created in 2008, and it introduced a blockchain-based digital currency in the world. The technology introduced the distributed leading system into a new monetary network. Hashgraph, DAG, and Holochain have emerged as blockchain alternatives with features such as security, stability, and speed. This article aims to understand the difference between Blockchain, Hashgraph, DAG, and Holochain and their functioning.

What Is Distributed Ledger Technology (DLT)?

distributed ledger is a sophisticated type of database. The Blockchain is the most widely used type of distributed ledger. Cryptography and distributed management by consensus are the two most essential aspects of DLT that ensure the ledger’s integrity, critical for financial assets.

The ledger can be either public or private. Private ledgers are stored on the servers of a few parties, and only they can update the ledger state; public ledgers are open for anyone to join and participate in the consensus. Intelligent contracts technology is an essential addition to the DLT. Smart contracts are self-executing pieces of code that allow the automation of specific processes, thereby saving money and time.

The distributed ledger database is shared across several devices through a peer-to-peer network in which every single copy of the ledger is transmitted, stored, and independently updated. A lack of central authority is a significant benefit. When the ledger is updated, each device provides a new transaction, and then the nodes vote on which copy is correct using a shared ledger. All the other nodes will update the latest copy of the ledger once an agreement has been established. Security is achieved through encryption keys and signatures.

Blockchain Technology

Blockchain technology is a distributed and decentralized data system that allows you to build a digital ledger of transactions and share it through a network of computers. It uses cryptography to enable every network participant to manipulate the header without a central authority securely.

Blockchains are secure, encryption-based, and network-distributable new data structures. Blockchain technology enables the transfer of any data or digital asset, including cryptocurrencies like Bitcoins. Blockchains, which Bitcoin created, achieve consensus among distributed nodes, enabling the transfer of digital goods without centralized transaction approval.

As a distributed ledger system, Blockchain tracks and validates every transaction, making it safe and dependable. All transactions are allowed by miners, making the transactions permanent and preventing them from being hacked. For peer-to-peer transactions, blockchain technology eliminates the need for any third-party or central authority. It also enables technology decentralization.

Hashgraph Technology

A Hashgraph is a distributed ledger offering the advantages of blockchain technology without the limitation of low speed. This distributed ledger technology also competes with the service providers such as AWS, IBM, Oracle,and Microsoft, not only with blockchains.

Leemon Baird, CTO, and co-founder of Swirlds, invented the Hashgraph technology. The significant advantage of this is technology is that it doesn’t need to validate the transactions. Instead of being bundled in blocks like a blockchain, transactions are timed using directed acyclic graphs.

Hashgraph is a suitable alternative to blockchain convergence. It employs a protocol that works as follows. Any node in the Hashgraph can distribute verified events on new input transactions and transactions obtained from others to its randomly selected peers. Such peer nodes add received events to a new event and then send them to other randomly selected peer nodes by providing accepted events from other nodes. The process is continued until all nodes are knowledgeable about what was generated initially. The quick integration feature of the protocol ensures that any new events can receive each node in the network.

DAG Technology

A directed acyclic graph (DAG) is a different type of data structure that assumes itself as a database that connects various pieces of information. They are composed of spheres, and the lines connecting them which are directed in the same direction. They are acyclic, i.e., you can’t return to the starting point if you begin and follow the graph at a given moment.

DAG is a graphical data structure with topological order that only extends the sequence from before to later. DAG is often used for data processing, scheduling, finding the best way to navigate, and compressing problems. It is also used for applications that require thousands of transactions per second scalability.

Holochain Technology

Holochain gives a framework for broadcast applications to add data, including bank assets, to your chain. The chains are combined to merge, split and interact, and this information is stored in a decentralized manner. The data has a hash that correlates to the data with a numerical biometric. For example, if someone interferes with the data, it notes the mistake between the data and hash, and the tampered data is rejected. Digital signatures ensure the authorship of the information Holochain is not encrypted, but it will operate on the same technology as BitTorrent as a distributed file system.

Holochain is a cryptographically secured application development framework for data integrity in decentralized peer-to-peer applications without approval. Essentially, Holochain enables multiple data storage space providers to run their independent sub-chains without any consensus algorithms. It is only necessary to keep a balance of accounts between different. Chains.

Differences Between Blockchain vs Hashgraph vs DAG vs Holochain

Classes Blockchain Hashgraph DAG Holochain
Running platforms The most well-known blockchain networks are Bitcoin and Ethereum. The only networks on Hashgraph are Swirlds and NOIA. The most prominent DAG-based networks are NXT, Tangle, and ByteBall. Holochain technology is a viable alternative to Ethereum, a dApp platform, due to its wide use-case. It is a Distributed Ledger Technology
Data Structure Data is organized in blocks in the order of transactions, and miners in the blockchain verify them. Virtual voting and Gossip on Gossip guarantees the majority validation of transactions. Each transaction is independent of the data structure, which is based on the directed acyclic graph mechanism. Since data is spread through several nodes on the platform, there is no network congestion.
Launch Time Nakamoto designed the first ever blockchain in 2008, from which the technology has grown into numerous uses beyond cryptocurrencies. on 16 September, Hedera Hashgraph starts. It is a DLT of the third generation, and 10,000 and above TPS is possible. DAG was first launched as Blockchain 3.0 on 9 November 2015. The release of Holochain DLT on 26 May 2018
Transactions per second Scalability and 4.6 TPS are very highly limited. As a result of the unique consensus mechanisms, scalability and Hashgraph can process more than 10,000 cryptocurrency transactions per second. The unique data structure provided by directed acyclic graphs ensures high scalability and ten thousand transactions per second. Holochain, unlike other blockchains, does not have a set number of transactions per second since it has a central point from which all transactions must pass.
In contrast to the blockchain, the Hashgraph, DAG and Holochain are considered as advanced technologies. However, that doesn’t mean they will replace blockchain. Due to blockchain’s features such as immutability and accountability, various products, organizations, developers still prefer to work with blockchain technology. It is also well-known, serving as the foundation for cryptocurrencies such as Bitcoin and distributed application platforms such as Ethereum. For transactions of medium to high value, blockchain provides strong guarantees and cost-effectiveness.

So, it is evident that replacing blockchain technology has proven to be a challenging task. On the other hand, we still lag in having a viable alternative for the distributes ledger technology.

What are the blockchain's challenges and limitations?
Blockchain technology will always be slower than centralized databases due to its distributed nature. When a new block is added to the blockchain, it must go through all of the same operations as a regular database. However, it must also perform other processes that have an impact on its performance. Here are four approaches:

1) Signature

2) Verification

3) Complexity

4) Security Flaws
