What is Blockchain Technology? | Easy Guide

We will be going to know about the Blockchain in this post. What is Blockchain Technology? Lets jump into the post and find it out with this easy guide.

So, If you’re a modern criminal, chances are you’ve used it to buy guns, drugs and even launder money. Sounds dodgy, right? But high profile institutions such as USAID and UNICEF have got a different perspective. They think it could be a force for good, helping the poorest people in the world.

Well, all that was about Blockchain. It’s a technology – a global online database that anyone, anywhere with an internet connection can use. Unlike traditional databases, which are owned by central figures like banks and governments, a blockchain doesn’t belong to anyone. And with an entire network looking after it, cheating the system by faking documents, transactions and other information becomes near impossible.



“Blockchain solves the problem of manipulation. When I speak about it in the West, people say they trust Google, Facebook, or their banks. But the rest of the world doesn’t trust organizations and corporations that much — I mean Africa, India, the Eastern Europe, or Russia. It’s not about the places where people are really rich. Blockchain’s opportunities are the highest in the countries that haven’t reached that level yet.”

Vitalik Buterin, Inventor of Ethereum

Blockchain Technology – How It Works?

Here’s how it works. Blockchains store information permanently across a network of personal computers. This not only decentralizes the information, but distributes it too. So how can a multi-purpose online database, whose users include criminals, work for everyday use?
How does it stay relatively hack-proof?

The answer is blockchain’s millions of users. They make it difficult for any one person to take down the network or corrupt it. The many people who run the system use their own personal computers to hold bundles of records submitted by others. The records are known as blocks.

Each block has a timestamp and a link to a previous block, forming a chronological chain. It’s like a giant Google doc with one key
difference. You can view it and add to it, but you can’t change the information that’s already there.

The blockchain enforces this by using a form of math called cryptography, which means records can’t be counterfeited or altered by someone else. Blockchain’s most famous application is Bitcoin.

Bitcoins – What is Blockchain Technology

Bitcoin is a digital currency that is created and held electronically – and you can send it to anyone, whether you know them or not. Bitcoin provides a level of anonymity not seen in modern times. That’s because unlike credit cards or PayPal payments, there are no middlemen like banks or financial institutions asking for your personal information and home address.

Instead, people from all over the world move the digital money by validating other people’s Bitcoin transactions, earning a small fee in the process. Where the blockchain comes in is verifying the ownership of this digital cash and making sure only one person is claiming it as their own at a time. Banks and businesses are rushing to adopt blockchain database technology.

Survey…

In a survey of 308 senior executives at U.S companies with $500 million or more in annual revenue, Deloitte found that 28 percent of respondents had invested $5 million or more in blockchain technology. Ten percent had invested $10 million or more.


But Why?

Why are they spending so much money? Well, to save money of course. When this study looked into the data of eight of the world’s largest investment banks, it found that blockchain could save them $8 to $12 billion dollars every year. Bet that $5 million investment doesn’t sound so bad now. But it’s not all good news for the big players, of course.

Blockchain Technology – On The Whole

"<yoastmark

Blockchain lowers the barrier for entry into the banking industry, and that means startups are popping up in pretty much every
market they operate in. If big banks and companies can’t keep up, they’re putting their own survival at risk. For the consumer, the future seems brighter with more security, less cost and better experiences.

Yet, blockchain could be the biggest game changer for the poorest in society. The technology is open to people living in low income countries or fragile states at risk of economic collapse.

Take a farmer with a small plot of land which is then flooded. The paper copy of the deeds to his land is washed away, resulting in the farmer having no proof of owning the land. Or perhaps he does have a digital copy on a government database but it is erased, altered or even destroyed in a political coup.

If the farmer had filed that deed on a blockchain, he could have avoided all these problems. Along with speeding up the flow of cash and providing a secure place to keep records – the benefits for the poorest in society are enormous. From protecting our identities to running autonomous vehicles to managing a world that is increasingly dependent on the internet
of things, the possibilities for blockchain technology seem endless.



But, whether it lives up to its promise remains to be seen…
More on this, soon.
