What Is Blockchain – A Layman’s Guide to Blockchain Technology

What is blockchain? And how can blockchain expertise be used? These are two widespread questions that normally come up after any dialogue on Bitcoin. We’ve already defined what Bitcoin is, and how to purchase Bitcoin in India, however this is a fast abstract – Bitcoin is a digital foreign money that’s “mined” by computer systems, by a strategy of fixing advanced mathematical equations encoded in an algorithm. This is completed utilizing a expertise known as blockchain, that not solely defines the foundations of the algorithm, however serves as a public ledger – all transactions (comparable to mining or buying and selling cash) have to be verified in opposition to the ledger, which ensures that the transaction is authentic, and clear. It’s an attention-grabbing concept that began to skyrocket in worth as Bitcoin turned common, significantly as a result of there is a onerous restrict on the variety of cash which can be doable within the system. As a end result, it is gotten tougher to “mine” every coin, and the worth of every coin has additionally gone up.

The strategy of mining by advanced algorithms makes Bitcoin a sort of cryptocurrency – and in reality it is simply one in all many common cryptocurrencies, with some well-known options being Litecoin, Etherium, and Dash. These all have totally different guidelines and totally different execs and cons – for instance, Litecoin is designed to be sooner to mine and commerce, whereas Etherium’s rising reputation means that there is a rising ecosystem across the foreign money. But these aren’t the one makes use of for blockchain expertise.

What is blockchain?

Brock Pierce, co-founder Blockchain Capital, a enterprise capital agency that invests in blockchain expertise corporations, explained the blockchain, in an earlier dialog with Gadgets 360, as a public-personal ledger of transactions, which doesn’t have any central management or single authority, or repository of knowledge. Think of blockchain like a public report – anybody could make modifications to it, supplied they’ve the precise credentials (authenticated utilizing algorithms described within the blockchain), however all these modifications are additionally public, together with who modified what. This signifies that any form of report may be broadly shared, but stored personal and restricted, and may be stored up to date with out shedding observe of who made the modifications.

That sounds simple sufficient, however the important thing to the expertise is that it would not depend on a centralised server to preserve observe of all this. Instead, the blockchain is distributed amongst all customers, and its validity is measured utilizing the blockchain algorithm. There’s no “master” copy that anyone particular person can entry or edit; in a method, the infrastructure of blockchain is slightly bit like a torrent file being shared.

This makes it an amazing foundation for a cryptocurrency, however there are literally extra methods during which it might probably come into play as nicely, with potential utility throughout totally different sectors, though the monetary corporations are in all probability those who’re most vocal about blockchain proper now.

How can Blockchain expertise be used?

There are loads of totally different potential purposes for Blockchain expertise. Mumbai-based Auxesis Group, which bought its begin as a analysis group roughly 5 years in the past at IIT-Bombay is among the corporations that is working in direction of constructing purposes on prime of blockchain infrastructure, and Akash Gaurav, its CEO, spoke to Gadgets 360 in an earlier interview about how blockchain expertise can be utilized.

“Our focus is on building a products suite for different industries, so that any organisation can quickly deploy blockchain,” mentioned Gaurav.

Auxesis labored on a mission for the Government of Andhra Pradesh. The authorities launched VISA playing cards and wished to use blockchain expertise to observe the transactions. The authorities wished the transactions to be accomplished on the blockchain infrastructure in order that it might be clear to all stakeholders, defined Gaurav, including, “otherwise Visa is the only person keeping the records.”

Other initiatives have been presently below NDAs, however Gaurav talks a couple of healthcare mission the place blockchain may allow higher sharing of knowledge between hospitals.

“A lot of data [from patients] is still collected in the paper format,” he defined, and in consequence, large digitisation drives have been underway across the nation. The problem turns into sharing knowledge between hospitals, with out elevating privateness points for sufferers. “One hospital cannot easily share the information of one patient with another hospital while guaranteeing the privacy of your data,” mentioned Gaurav. “But with blockchain, the treating doctor could update the patient’s data, and if they go to another hospital, that data is available, but it can only be accessed with the patient’s digital consent.”

Lots of potential for companies too
Beyond currencies, and authorities makes use of for sustaining information, blockchain expertise has different potential makes use of too. For instance, Yes Bank used blockchain to handle vendor financing for its purchasers. With this, distributors may submit invoices utilizing the ledger, and purchasers may deal with funds seamlessly.

Finacle, whose expertise powers many main banks in India, has additionally been wanting on the way forward for blockchain. Some areas the place it may discover use proper now are worldwide remittances, and identification administration, in accordance to Rajashekara V Maiya is Associate Vice President and Head – Finacle Product Strategy, in an earlier interview. One of the challenges that he foresees is sluggish adoption, as a result of there is not any benefit to early adopters, he mentioned. “Unlike other digital technologies – mobility, analytics, cloud and so on – which offer competitive advantage to early adopters or monopolists, the distributed ledger needs a minimum of two parties to even function,” mentioned Maiya, including, “On the blockchain, it only pays when you collaborate. That will not be easy for banks, who are slugging it out in a fiercely competitive market.”

“Indian companies have only been looking at this technology for only about a year right now but already a lot of development has been done and we aren’t very far behind because that was the early stages where things were moving more slowly,” mentioned Auxesis’ Gaurav. “So now when we make use cases, they learn from these scenarios”, Gaurav added. Bajaj, Pidilite, and others are looking at things like supply chain using blockchain infrastructure, and there are more big corporations that are also working to evolve the processes.”

At the identical time, the benefit of the federal government taking an curiosity in blockchain is that a big consumer base comes up rapidly, which may be helpful in growing the expertise, Gaurav mentioned. “Right now, the Aux Ledger has more than 50 million users, which provides us an edge over any other blockchain organisation in the world,” he mentioned. “When people are talking about doing pilots, we’ve already got some live projects”,he added.

Cryptocurrency is not essentially the long run, although blockchain is probably going to be
Johan Gerber, Executive Vice President of Security and Decision Products, MasterCard, mentioned on his go to to Bengaluru when he additionally spoke to Gadgets 360. Gerber was within the metropolis for Mastercard’s first Innovation Forum occasion in India, and confirmed us different strategies for securing transactions, and the query of cryptocurrency got here up. “Blockchain, yes,” he mentioned emphatically, persevering with, “cryptocurrency though, they’re still facing issues and figuring it out. Fiat currency [government backed money] is still a larger and more open ecosystem. And it’s not necessarily more secure, and it’s a lot less regulated. I believe blockchain technology has a big role to play, but not necessarily restricted to cryptocurrency.”
