Blockchain & Distributed Ledger Technology (DLT)


Blockchain technology is a secure software architecture that allows data to be saved in a safe and decentralised manner. Learn more! One of the most engaging topics in finance right now is the rise of cryptocurrencies. Cryptocurrencies are based on a technology called blockchain. So, what really is the blockchain and what makes it such a revolutionary technology? Understanding blockchain has to be taken in short steps.

Before we can understand what the blockchain is, we must understand what a distributed or decentralised ledger is. Conventionally, most financial networks are centralised. Clearing and settling payment requests by banks, for example, are done using a centralised ledger. A ledger is a written or computerised account of all the transactions a business completes. A centralised ledger, therefore, is a record of all the transactions conducted by a set of companies.

In the banking sector, that would include all the banks, NBFCs, etc. Once a transaction has been recorded on the centralised ledger, the companies involved in the transaction adjust the levels in their own internal ledgers to reflect the change. It is absolutely imperative, therefore, that the centralised ledger is updated accurately and safely, and in a timely manner so as to maintain the integrity of the system that is based on it.

Now, a newer form of ledger-keeping has been emerging over the last decade or more, where there are more participants in the actual maintenance and updation of the ledger. A decentralised ledger is when these tasks are assigned to some of the entities in a network while a distributed ledger is when these tasks are assigned to everyone on the network.

Blockchains, depending on how they are set up, can be either decentralised or distributed ledgers. In simple terms, blockchain technology is a secure software architecture that allows data to be saved in a safe and decentralised manner. What is even more useful is that the chain is immutable. That is, it cannot be changed, altered, deleted or in any way modified. In these kinds of networks, any changes to the ledger—additions, subtractions, etc—must be approved by the majority of the entities on that network.

That is, if a change is proposed, then most of the nodes on the network have to agree that this is a legitimate change and that is must be recorded on the blockchain. Each of these changes, once approved and legitimised, joined the blockchain as an additional block. Different networks have different rules on what kind of consensus mechanism they want to employ. Smaller networks can afford to require a full consensus, where a transaction is approved only when all the nodes approve it.

Larger networks, with thousands, if not millions, of nodes cannot afford such a strict protocol as each transaction would then take a very long time to be verified. Instead, they adopt a majority consensus protocol, where a transaction is approved if a majority of the nodes agree that it should be approved. These consensus protocols make it very difficult for a bad actor to falsify a block. Blockchain technology is incredibly versatile and can be applied in varied use-cases.

In general, these blockchains can be divided into two broad categories: public and private blockchains. Public blockchains are open to any who would like to participate. Bitcoin was the very first public blockchain network and is one of the largest, with research showing that there are about 5 million Bitcoin users in the world. Public blockchains also are laxer in terms of identity information and most users often use pseudonyms.

Businesses also often use private blockchains, were membership is limited to only those invited onto the network. In such blockchains, the transactions on the blockchain, while visible to members, are not visible to those outside the blockchain. Several companies have begun to use these to conduct internal transactions between branches of the same company. As stated above, blockchains are very versatile tools and so they can be applied in a variety of ways and in multiple sectors.

Smart contracts are one essential way in which blockchains are used. However, the most popular application of blockchain technology by far is in cryptocurrencies. The next article in this series will delve further into the topic of blockchains to see what exactly makes them work, how the nodes can verify to such a high degree of surety that a transaction has taken place, and how they are so secure.

What Is Blockchain? The ‘Transformative’ Technology Behind Bitcoin, Explained

Blockchain is one type of a distributed ledger. Distributed ledgers use independent computers referred to as nodes to record, share and synchronize transactions in their respective electronic ledgers instead of keeping data centralized as in a traditional ledger. Blockchain organizes data into blocks, which are chained together in an append only mode. Distributed ledger technology DLT could fundamentally change the financial sector, making it more efficient, resilient and reliable. Understanding Poverty Topics Financial Sector brief. Email Print.

Blockchain technology is used for more than just bitcoins. Instead of parking the car in the garage, this model offers a simple source of income for the.

How Is Blockchain Technology Making Cryptocurrency Trading More Secure?

Ever more application areas for blockchain technology are being developed. But how does the technology work? We have the answers to these key questions. Put simply, a blockchain is a continuously extendable chain of records known as blocks. These blocks are linked together by a cryptographic procedure. In principle, any kind of digital information can be recorded and saved with a blockchain. The distinctive characteristic of a blockchain network is that the recorded information is valid and transparent, while users remain anonymous and can interact directly with each other.

Few people understand what it is, but Wall Street banks, consultants, and celebrities are buzzing about blockchain technology. It's hard to remove blockchain from Bitcoin, so we'll start with Bitcoin as we work to understand this technology's potential. Download our free report to get all the trends. The impact of blockchain tech could be huge. Big corporations — like Walmart and Pfizer — have completed blockchain pilots, with many more partnering on projects ranging from remittance to title transfer.

Blockchain technology allows for the creation of a decentralised public record of digital information. The data the block is stored in a public database the chain and can consist of any information.

History of blockchain

Blockchain technology can enhance the basic services that are essential in trade finance. At its core, blockchain relies on a decentralised, digitalised and distributed ledger model. By its nature, this is more robust and secure than the proprietary, centralised models which are currently used in the trade ecosystem. Blockchain technology creates a viable, decentralised record of transactions — the distributed ledger — which allows the substitution of a single master database. It keeps an immutable record of all transactions, back to the originating point of a transaction. This is also known as the provenance, which is essential in trade finance, allowing financial institutions to review all transaction steps and reduce the risk of fraud.

You can call it a ledger. The ledger in your laptop has become a distributed ledger.

A prime example to highlight the ambiguity of the term blockchain is the tension between so-called permissionless and permissioned blockchains.

Blockchain in Simple Terms

Summary: Everyone has probably heard about blockchain, but do we really understand how this technology works and what application it has found in modern life? In this article, we will look at the basic concepts of blockchain and explain everything you need to know in simple terms. With the ongoing cryptocurrency bull market, almost everyone has heard about this tech at least once in their lives. After all, the decentralized ledger that makes up the blockchain is essential for registering crypto transactions.


A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. Blockchains are used for recording transactions made with cryptocurrencies, such as Bitcoin , and have many other applications. Each transaction added to a blockchain is validated by multiple computers on the Internet. These systems, which are configured to monitor specific types of blockchain transactions, form a peer-to-peer network. They work together to ensure each transaction is valid before it is added to the blockchain.

A blockchain is a growing list of records , called blocks , that are linked together using cryptography.

In the rapidly evolving environment of the international supply chain, the traditional network of manufacturers and suppliers has grown into a vast ecosystem made of various products that move through multiple parties and require cooperation among stakeholders.
