Blockchain and Distributed Ledger Technology DLT


Validators are able to come to an agreement through consensus protocols to make important decisions, like whether to postpone legitimate transactions or cancel fraudulent transactions. As you’ll learn in almost any guide about blockchain basics, validation for blockchains is sequential. For example, Block 1 must be created before Block 2, Block 2 before Block 3, and so on. This often creates a challenge since full nodes have traditionally needed to download the entire blockchain history. However, many projects are working on blockchain scalability solutions to ensure that blockchain application development can support large user bases. Distributed ledger technology is a platform that uses ledgers stored on separate, connected devices in a network to ensure data accuracy and security.

In a letter-of-credit deal, for example, two companies opted for a paperless solution and used blockchain to trade nearly $100,000 worth of butter and cheese. By doing so, a process that previously took up to ten days was reduced to less than four hours—from issuing to approving the letter of credit. Distributed ledger technologies can be categorized in terms of their data structures, consensus algorithms, permissions, and whether they are mined.

  • Loyyal—Powered by blockchain and smart contract technology, this loyalty and rewards platform creates more customized programs that even allow for multi-branded rewards.
  • DLT can be used to create secure and verifiable digital identities that can be used for a variety of purposes, such as verifying the identity of individuals for financial transactions or voting.
  • Through this conversion, he created the first Shanxi bank specialised in silver exchange .
  • The technology is based on atomic swaps—an invaluable tool for exchanging one cryptocurrency with another (e.g. 1000 BTC with LTC) and no need for a trusted third party.
  • Ethereum is a blockchain-based software platform with the native coin, ether.

Now that we’ve looked at the distributed ledger technology definition and various examples, let’s highlight how Komodo’s solutions support blockchain use cases. There are many features that make Komodo unique from other blockchain platforms. Three examples are multi-chain design, independent chains, and customizable modular solutions. Public ledgers, oftentimes called permissionless ledgers, are usually open to everyone.

Where DLT is used

If the initial dot com boom is anything to go by, then there will be many casualties in the short term but serious disruptions in the medium and longer term. ABRA—A global app and distributed ledger technology examples wallet that allows you to buy, invest and store 20 crytopcurriences including Bitcoin, ethereum, litecoin and more. Warranteer—A blockchain application that allows consumers to easily access info regarding the products they purchased and get service in the case of product malfunction.

  • Think about the banking limitations of different countries around the world.
  • Depending on the use case, this can significantly boost trust and confidence between participants.
  • In contrast, DLT systems can use a variety of different structures to store and manage data, such as graphs, tables, or trees.
  • DAG stands for ‘directed acyclic graph’ and has different mechanics than blockchain.
  • Any changes to the ledger, such as moving data from one block to another, are recorded across all nodes.

A blockchain uses several technologies like digital signatures, distributed networks, and encryption/ decryption methods including distributed ledger technology to enable blockchain applications. DLT is a digital system that was created to record transactions of assets in multiple places with no central data storage. In banking and fintech industries, distributed ledger technology brings various benefits for both internal and external transactions.

Challenges of DLT implementation

As a result, banks and retail vendors could easily find out the legitimate transactions and verify their authenticity. Banks and financial institutions, alongside other vendors, can verify transactions through the digital profile of an individual. Another important facility with use cases of distributed ledger technologies refers to speed. Smart contracts help in avoiding conventional approval processes. Therefore, distributed ledger technologies can help in removing traditional intermediaries from conventional transactions.

Afterward, the nodes update the versions of the database so that all the devices or nodes will be of the same version. They are held, reorganized, and controlled by individuals called nodes. James has 15+ years of experience in technologies ranging from Blockchain, IoT, Artificial Intelligence, and Augmented Reality. He is committed to helping enterprises, as well as individuals, thrive in today’s world of fast-paced disruptive technological change. Distributed ledger technology uses in fraud prevention and security. One of the notable examples of financial risks is Wells Fargo, which had to pay hundreds of millions of dollars as US Federal Trade Commission fines.

As a result, DLT processes may lead to slower processing capabilities or higher costs of use. In addition, some DLTs such as Bitcoin require a significant amount of energy to maintain the network and process transactions. DLT allows for smart contracts, agreements that automatically execute or complete based on prevailing conditions. For example, an insurance claim may automatically release funds once the claim has been processed. This limits error, and DLTs make it more difficult for precarious activity by bad actors. Distributed ledgers are maintained by a network of nodes, each of which has a copy of the ledger, validates the information, and helps reach a consensus about its accuracy.


DLT data structure types include linear data structures to more complex directed acyclic graph and hybrid data structures. DLT consensus algorithm types include proof-of-work and proof-of-stake algorithms and DAG consensus-building and voting algorithms. PoW cryptocurrencies are generally either ‘mined’ or ‘non-mined’, where the latter typically indicates ‘pre-mined’ cryptocurrencies, such as XRP or IOTA.

Distributed computing is not new—businesses and governments have been using the concept for several decades. In the 1990s, it became possible for multiple computers and users in different locations to solve problems and return the solutions to a central location.

One of the biggest uses of DLT we see today is to keep a record of monetary transactions.

DLT enables secure, transparent and decentralized transactions without the need for a central authority. Though this naturally lends itself to financial records, DLT can record any type of transaction even without financial undertones. Many factors make them inefficient, inaccurate, and susceptible to corruption or losses. Fujitsu, a global data and information technology company, has designed distributed ledger technology to enhance supply chain transparency and fraud prevention by securing and tracking data. Multiple organizations can share the responsibilities of maintaining a blockchain.

Said simply, all blockchains are DLTs, but not all DLTs are blockchains. Well, now it’s time we understand that there is more to DLT than blockchain. Databases shared across a network and can be accessed at various geographical locations. Finally, though immutability is one of the strengths of DLT, it can also be a weakness. As all transactions are publicly viewable, it may make it difficult to have true privacy for more sensitive types of transactions.


Imagine that someone is looking to buy a concert ticket on the resale market. On these sites, every ticket is assigned a unique, immutable, and verifiable identity that is tied to a real person. Before the concertgoer purchases her ticket, the majority of the nodes on the network validate the seller’s credentials, ensuring that the ticket is in fact real. Distributed ledgers use independent computers to record, share and synchronize transactions in their respective electronic ledgers .

These blocks form a chain of data as an asset moves from place to place or ownership changes hands. The blocks confirm the exact time and sequence of transactions, and the blocks link securely together to prevent any block from being altered or a block being inserted between two existing blocks. Another core banking activity, trade finance facilitates transactions between buyers and sellers worldwide.

DLT holds many benefits over more traditional centralized ledger systems. Because DLT is a decentralized system, there is no central point of control or failure. This makes DLT more resilient to attacks and less vulnerable to system-wide failures.

Distributed ledger technology is a general term, with blockchain being one subcategory of DLT technology. Directed Acyclic Graph , Holochain DLT, and other subcategories of DLTs exist, but they aren’t as commonly known yet as blockchain. In this article, we’ll define exactly what are distributed ledgers and explain how they work to verify the accuracy of data. Ethereum is a blockchain-based software platform with the native coin, ether.

Trade finance lubricates the wheels of international commerce, providing credit, payment guarantee and insurance on terms that benefit all parties. Once again, this is traditionally a paper-intensive iterative process that involves several parties and takes time. Ethereum, the second most popular name in blockchain technology, suffers from certain shortcomings. Few other players collectively known as the Ethereum killers, such as Solana, Cardano, are capitalizing on the very flaws of the Ethereum blockchain.

But the words decentralised and distributed are linked but do not have the same meaning. For example, you can have a centralised, distributed system and decentralised, distributed system . Anyone who is a developer will be familiar with using Git to manage different versions of the code they are writing.
