Ledgers historically have required a central authority to validate the authenticity of the transactions recorded in them. They became digitized with the rise of computers in the late 20th century, although computerized ledgers generally mirrored what once existed on paper. Ledgers - which are essentially a record of transactions and similar data - have existed for millennia in paper form. The great advancement of DLT is its ability to minimize or eliminate the often time-consuming and error-prone processes needed to reconcile the different contributions to the ledger, ensure that everyone has access to the current version and that its accuracy can be trusted. Similarly, multiple organizations working together typically hold their own data and contribute it to a central ledger controlled by an authorized party only when requested or required. A company, for example, might have different bits of data held by each of its divisions, with divisions contributing that data to a centralized ledger only when required. Organizations have long gathered and stored data in multiple locations either on paper or in siloed software, bringing the data together in a centralized database only periodically. It's important to note that the concept of a distributed ledger is not new. Financial services, healthcare and pharmaceutical sectors were early leaders, and supply chain management a common application. Interest in distributed ledger technology grew significantly in the decade after the 2009 launch of bitcoin, a cryptocurrency powered by blockchain technology that was the first to demonstrate that the technology not only worked but could scale and remain secure.ДЇrom that time onward, organizations across industries experimented with DLT and how it could be used in enterprise processes. DLT's main difference from traditional, centralized ledgers is that a copy of the ledger is distributed to each node on the network, and every node can view, modify and verify the ledger, which helps ensure trust and transparency. This transparency of DLT provides a high level of trust among the participants and practically eliminates the chance of fraudulent activities occurring in the ledger.ДЄs such, DLT removes the need for entities using the ledger to rely on a trusted central authority that controls the ledger, or an outside, third-party provider to perform that role and act as a check against manipulation. As a result, all other entities can see who is using and modifying the ledger. This architecture represents a significant change in how information is gathered and communicated by moving record-keeping from a single, authoritative location to a decentralized system in which all relevant entities can view and modify the ledger. The technology also creates an immutable database, which means information, once stored, cannot be deleted and any updates are permanently recorded for posterity. It works on a computer network spread over multiple entities or locations.ДLT uses cryptography to securely store data, cryptographic signatures and keys to allow access only to authorized users. What is distributed ledger technology?Дistributed ledger technology (DLT) refers specifically to the technological infrastructure and protocols that allow the simultaneous access, validation and updating of records that characterizes distributed ledgers.

A distributed ledger can be used to record static data, such as a registry, and dynamic data, such as financial transactions.Д«lockchain is a well-known example of a distributed ledger technology. In a distributed ledger, each node processes and verifies every item, thereby generating a record of each item and creating a consensus on its veracity. Unlike traditional databases, distributed ledgers have no central data store or administration functionality. Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time.
