A single entity cannot manipulate the digital databases. So, whether it is a blockchain, a variation of Blockchain, or a completely different distributed ledger alternative, the data must be distributed to nodes in a network. There isn’t a single way DLT works because the term is a general class for more technologies that may be somewhat similar but have different ways of functioning. Being spread over multiple nodes, the distributed ledger has no single point of failure and is able to continuously synchronize at low costs, creating a single source of truth for all users. Because it’s tamper-proof, the risk of corruption is decreased, and the need for regulation is lowered. In a distributed ledger, the information is easy to access and view by users. Also, they are centralized points of failure and are inefficient to update and synchronize constantly. However, they are open to manipulation by members within those organizations, which creates many legal requirements that come with even more costs. Mostly, they cannot be accessed without special authorization for the benefit of other systems. Right now, the ledgers are kept secret within the databases of centralized organizations. Where distributed ledgers come inĭistributed ledgers are formed of records regarding any transaction backed by a decentralized geographically spread network, eliminating the need for a central authority. But even at a national level, keeping track of a centralized ledger turned out into a massive slow system that needs lots of intermediaries, costs a lot to maintain, and is prone to errors. So, centralized ledgers have turned into a laborious attempt to keep track of all the truth worldwide.Īlthough it sounds like a madman’s job, the world did it. The modern economy evolved around centralized ledgers, but a database is only as reliable as the organization maintains it. In most cases, the ledgers must be communicated from one entity to another to reach a consensus about the current state of affairs. But since ancient times, economic and social relationships have become more and more complex.Ĭountless institutions and businesses keep ledgers regarding finances, employment, property ownership, and much more. Once moved from analog to digital, ledgers became computable and searchable digital databases that were more efficient. But with the evolution of technology, ledgers started being digitized, and complex database technologies were born. The main central authority of those ledgers was always the state.Īlthough the ledgers developed together with society, until recently, they only existed in physical format. They were used to keep track of who owns what, which citizen belongs to what city, what’s his social status, or what economic relations different cities have. The ledgers go back into human history and appear in antiquity as stone tablets and scrolls. What is a ledger, though?Įssentially, a ledger is an accounting instrument that keeps a record of all economic and social relationships and their changes in order to keep consensuality about facts. One of today’s best-known distributed ledger technology is Blockchain. The technology innovates by allowing the distributed ledgers to be replicated, shared, and synchronized even though they are spread on multiple devices in different locations. In DLTs, every member can contribute to the stored data not on a central cloud-based platform but locally on each device on the network. Different types of data, like transactions and ownership, are recorded and managed from multiple places at once. What is Distributed Ledger Technology?ĭistributed Ledger Technology is a digital system of distributed ledgers. So, let’s see how we can solve that with DLT. But although technology evolved, we’ve got ourselves in a situation where we work with copies of copies of copies to agree on information that relies on databases that do not communicate with each other. The electronic databases we developed in our days brought new levels of efficiency. And since ancient times, people have managed to do that with ledgers. In our world, these facts go from ownership to all sorts of transactions and situations. But when you have 7 billion people on Earth and not all are well intended, it’s quite hard to agree on what’s true and what is not. But that is meant to change through the implementation of Distributed Ledger Technology (DLT).Ī big part of our society’s functioning relies on agreeing on facts. With all the physical registries kept by different organizations in different places and databases that never communicate, it becomes quite troublesome to try proving you own something, even to simply buy/sell a proprietary.
