Blockchain technology is changing the way the world works, whether we’re talking about finance, government, health care, or even education. But what exactly does it do? And why are so many businesses and people so excited about blockchain technology?
In this article, we’ll answer all of these questions and more to give you an idea of how blockchain can work for you and your business – but also why you need to be careful in the way that you implement it.
Blockchain in 30 Seconds
Blockchain is a distributed ledger that contains an ever-growing list of records. Each one of these records or blocks contains a timestamp, a link to a previous block, and transaction data. By design, blockchains are inherently resistant to modification of data—once recorded, information can never be erased or overwritten. All transactions on blockchain networks must be approved by consensus among participants in that network—all recorded information cannot exist without mutual agreement about its validity.
Is Blockchain Secure?
The next layer of security can help ensure that you are in full control of your digital assets, without compromising your privacy. The blockchain allows users to store their digital assets on a network. This network consists of computers around the world connected through an encrypted, decentralized protocol. Each user has a unique encryption key that gives them access to their own piece of data or block in a chain of blocks.
No user holds all of any data: rather, each owns only their own information and has no ability to breach or steal from other’s accounts because there is no way to decrypt another person’s encryption key. If someone tries to hack into your account from theirs (this can happen due to vulnerabilities in software), they won’t be able to access anything because only you have access with your keys.

Can Blockchain Create Jobs in the Future?
A lot of concern has been raised about how artificial intelligence will take over jobs in today’s workforce. Though AI can make many jobs much easier, we are also seeing new companies rise up to focus on applying technology to create new jobs. One of these companies that uses blockchain to do just that is VeChain (VEN).
The company uses smart chip technology to add authenticity to a wide range of products, including luxury goods, food items, auto parts, wine and spirits, etc. By building trust into their system they allow people who buy these goods direct access to data that would usually be held by a central authority. VeChain creates new job opportunities through their business model where you could become a trader or consumer of their product.
What Are Smart Contracts Good For?
Smart contracts are self-executing code. The core technology behind cryptocurrencies like bitcoin, Ethereum, and Litecoin. Smart contracts can also be used to exchange money or anything of value. Simply put, they’re an automatic way to buy or sell a product or service online – even legal agreements (for example marriage).
And smart contracts cut out all kinds of intermediaries from your commercial transactions – that includes banks, brokers, governments, etc. Basically, smart contracts remove middlemen from just about every transaction you make! So how does that work? Well for example let’s say you want to purchase your favorite single Let Me Love You by DJ Snake featuring Justin Bieber.
How Blockchain Protects Your Privacy Online
To understand how blockchain works, let’s look at a few examples. In 2008, Bitcoin became the first digital currency to eliminate a central point of control by maintaining a public ledger that records every single transaction ever made. As new transactions are registered, they are verified by computers on different networks.
The new blocks of data that make up each transaction must be properly linked to older blocks—and with them all transactions ever made. This process forms an unbroken chain that goes all the way back to Bitcoin’s originator — you! There’s no other way for hackers or thieves to go back in time and change a transaction because there simply isn’t any information stored in any location besides where it was originally recorded.
Do Cryptocurrencies Have a Future in Retail Payments?
Let’s start with what blockchain technology isn’t. It isn’t bitcoin, although most of us think of them as synonymous because cryptocurrency was often touted as being part of blockchain technology. Cryptocurrencies like bitcoin are one application for blockchain; however, cryptocurrencies have been around for years but didn’t come into mainstream use until late 2017 or early 2018 when bitcoin became more valuable than gold.
In addition to expanding our supply chain capabilities to support other currencies, many companies started looking at applying blockchain technology to their existing applications. For example, credit card processors that were originally built in 1996 can now be updated using blockchain technology so they are not vulnerable to cyber attacks.
The Benefits of Blockchain for Healthcare
There are numerous benefits of blockchain technology, but when applied to healthcare, these benefits can be used to revolutionize everything from patient records to medical research. Several companies in healthcare have already begun using blockchain technology to store and share sensitive patient data, while others are developing new forms of medical research based on blockchain.

The Pros and Cons of Blockchain Technology
Today, there’s a lot of hype surrounding blockchain technology. Some people are even going so far as to say that blockchain will be as disruptive as it was when personal computers came onto the scene in 1980. But before you start salivating over potentially investing in a cryptocurrency, take some time to understand how blockchain works.
In addition to being able to create decentralized apps that cut out middlemen by eliminating fees (think Uber but without Uber), blockchains can also improve things like supply chain management, identity management, healthcare record-keeping (especially through patient-controlled records), voting systems and so much more. So what exactly is blockchain?
