Distributed Ledger Technology (DLT): Definition and How It Works

Distributed Ledger Technology (DLT): Definition and How It Works

Since the launch of Bitcoin in 2009, Distributed ledger technology grew in popularity. Since then, businesses from several industries have experimented with DLT to see how it may be used to transform the transfer of data, transactions, and storage.

Distributed ledger technology (DLT) is gradually transforming the banking sector and businesses by making them more efficient, and reliable. Now, Financial services, pharmaceutical companies, and the supply chain management industry are all striving to study and explore how this revolutionary technology works.


To help you understand the whole concept of Distributed ledger technology and how it works, we’ve put together this article. In this post, you’ll be learning what DLT is all about, how it functions, its advantages, and its applications.

What Is Distributed Ledger Technology (DLT)?

Distributed ledger technology (DLT) is the technological infrastructure and protocols that allow for simultaneous access, validation, and updating of records. It operates through a computer network that cut across numerous places and organizations.

Additionally, DLT uses encryption to store data safely and to ensure that only people with the proper authorization can access it. The technology also produces an immutable database, which ensures that information is never lost after it has been saved and that any revisions are kept for all time.

Similarly, a distributed ledger is an openly shared database that is synchronized and accessible by multiple users across numerous sites, organizations, or locations. Each node in a distributed ledger processes and validates every item, making a record of each item and reaching an agreement on its authenticity.

In a nutshell, the DLT is based on the concept of a “decentralized” network as opposed to the traditional “centralized” method, and it is gradually changing the whole ballgame of industries and entities that have historically relied on third party.

How Does Distributed Ledger Technology Work?

Over the year, technology has made record-keeping and ledger upkeep quite quick and convenient. However, in the modern world, distributed ledger technology allows for more timely, decentralized, and secure storage of data on computers.

A distributed ledger is a ledger of any transactions or contracts that are maintained in a distributed network across several places and people, doing away with the requirement for a central authority to maintain oversight and prevent fraud. 

Hence, all the data on the ledger can be accurately and securely kept and retrieved using cryptography. After being stored, the data transforms into an immutable database that is governed by network policies.

Typically, one of the most common forms of distributed ledger technology is the blockchain, it groups transactions into chains of blocks before broadcasting them to network nodes.

Tangle, which is another type of DLT, is designed for IoT ecosystems. Tangle is a feeless, scalable distributed ledger, designed to support trustworthy data and value transmission between humans and machines. Other popular distributed ledger technologies include Corda and Hyperledger Fabric.

Advantages of Distributed Ledgers

Although DLT adoption is still in its early stages, the technology has already demonstrated its capacity to provide consumers with numerous benefits, including the following:

#1. Decentralization

Because of errors made at the level of the central authority, a centralized network may have a single point of failure that can bring the entire network to a halt. However, distributed networks do not run the risk of having a single point of failure. The decentralized structure also raises the trust level among participating nodes. Hence, the cost of transactions is significantly reduced by the decentralized nature of validation.

#2. High Transparency

While centralized ledgers are vulnerable to cyber-attacks, distributed ledgers are intrinsically more difficult to attack. Because the insertion of data must be approved by nodes using multiple consensus techniques, these records are resistant to malicious alterations by a single entity. As a result, any attempt to alter or change data in the ledger is immediately mirrored across all nodes of the network, preventing illegitimate transactions.

#3. Time Efficiency 

Because the Distributed Ledger is decentralized, no central authority is required to validate transactions every time. Consequently, distributed ledgers eliminate operational inefficiencies, and shorten the time it takes to process a transaction.

#4. Scalability

DLT is more scalable because various forms of consensus methods may be utilized to make distributed ledger technology more reliant, fast, and up-to-date. As several advanced DLT technologies have been introduced in recent years. Such as Holochain and hashgraph, which are regarded to be more advanced and secure forms of Blockchain DLT. Although Blockchain is a sophisticated and safe technology, DLT provides a path to more advanced technologies.

#5. Protection of Intellectual Property

Similar to NFTs, which use blockchain technology to store proof of ownership making it is hard for them to be copied. Digital ledgers make it easier to track intellectual property rights like ownership of art, commodities, music, film, and more. As a result, creators and artists can have better control over their works of art.

What is the Use of Distributed Ledgers?

Distributed ledger technology is gradually transforming the way governments, institutions, and corporations work. It can assist governments in collecting taxes, issuing passports, recording land registries, and distributing Social Security benefits.

DLT is transforming a variety of sectors, including finance, arts and entertainment, assets, healthcare, and commodity supply chains.

FAQs About Distributed Ledger Technology

What is DLT?

Distributed ledger technology is a peer-to-peer digital system that records transactions between parties in numerous locations at the same time. DLT uses cryptography and consensus techniques to enable participants to share an immutable replica of the same ledger. Instead of keeping data centrally as in a typical ledger, distributed ledgers use independent computers known as nodes to record, share, and synchronize transactions in their electronic ledgers.

What are the benefits of Distributed Ledger Technology?

Some of the advantages of DLT include decentralization, transparency and easier auditability, high transaction speed, cost reductions, and automation.

How is a DLT different from a blockchain?

DLT is a decentralized database that is administered by several contributors and distributed over multiple nodes. Blockchain involves a type of distributed ledger technology in which they record transactions with an immutable cryptographic signature known as a hash.

How does blockchain based DLT work?

A blockchain is a form of digital record that distributes transactions across a decentralized computer network. Instead of storing transactions in a single centralized server, distributed ledgers use separate nodes to record, share, and synchronize transactions in their electronic ledgers.


Since the development of blockchain technology, distributed ledger technology (DLT) has been observed to significantly improve record-keeping by introducing decentralization.

Although the usage of DLTs is still in its infancy, the technology is gradually gaining traction from various businesses and agencies.

Today, specialists are advocating DLT as a significant technology that not only has the potential to significantly improve current procedures but also to inspire creative ideas.

Now, many institutions, including those in the public and private sectors, are investigating ways to use this technology to keep track of transactions. Therefore, DLT is the technology of the future!
