The term Blockchain seems to be trending in the world of business and technology nowadays; it’s being utilized across different industries and fields, from finance and healthcare to publishing, media, art and entertainment, etc. The reason behind this huge demand of Blockchain lies in its potential to transform the way businesses work by removing intermediaries and enabling trustless transactions between two parties directly. But just how does Blockchain works? And how does it ensure that there are no third parties involved in transactions? Let’s take a closer look at Blockchain technology!

A brief introduction to blockchain
The blockchain is a new way of storing and exchanging data. Since it can't be altered by any one person, data is secure on the blockchain. More importantly, because it's decentralized (built with peer-to-peer networks), data isn't stored on just one server: It's distributed among many people. This means that even if one server is shut down, there are still others that would have a copy of the data. Blockchain also allows for smart contracts to be created without intermediaries to verify them, making transactions more secure and less expensive overall. That's why blockchain has become an extremely useful tool in some industries where data integrity is crucial. For example, financial institutions like banks could use blockchain technology to track all of their assets at all times. Healthcare providers could use blockchain to securely store patients' records, as well as track medications being used at home. With so many different uses for this amazing technology, we're excited about what will happen next! The blockchain not only stores data but also encrypts it with military-grade cryptography. Data inside a blockchain cannot be hacked or tampered with by anyone. Also, data cannot be changed once saved within the blockchain meaning whatever happened stays in the blockchain forever. Blockchain brings decentralization which makes data impervious to censorship, tampering and hacking attacks; hence, these facts make data security of utmost importance for most entities nowadays
Moreover, transparency via Blockchain enhances trust between two or more parties in various domains from supply chain management to tracking raw materials from their origin point till they reach the consumers.

How does blockchain benefit businesses?
A database provides a means to store, organize, and share information that can be accessed at any time from any location. Blockchain is an online database that stores information on its participants' computers. This system has gained popularity in recent years due to its decentralized nature and its security features.
NFT stands for Non-Fungible Token which are basically like cards or trading cards. These tokens represent certain assets, such as cryptocurrency or other items of value. In the scope of video games, they are what you would use to buy things with on an online marketplace (like Fortnite)
Blockchain is a career choice that helps solve problems not just for one company but across many industries and companies around the globe. Within the scope of video games, it may seem strange that someone might want to pursue blockchain as their career choice, but there are lots of non-fungible token opportunities out there. Video gamers who have skills and knowledge about blockchain technology could potentially find jobs in both the gaming industry as well as being involved with blockchain development outside of gaming. For example, non-fungible tokens can play an important role in facilitating digital ownership by creating cryptographically unique digital objects that are difficult to duplicate without permission. Blockchain developers could also contribute to projects related to virtual worlds where people work together and buy/sell items using these types of digital assets.

What are some of the major companies using blockchain?
One of the major companies that is using blockchain is Marriott, who has partnered with IBM to develop a way for guests to access their reservations and check out faster. Blockchain is also being used in health care, travel, banking and finance, and real state. In terms of travel, the Singapore Airlines Group wants to use blockchain technology to reduce fraud when selling seats on flights. In health care, there are two major uses: supply chain management and patient record management. Supplier records are stored on a private ledger accessible only by authorized members; this reduces fraud while simultaneously protecting sensitive data from hackers. Similarly, patient records would be stored privately within each individual hospital but would be shared across hospitals if necessary in order to provide quality medical care more efficiently; this benefits both providers and patients because it prevents waiting for transfers of records between different hospitals during emergency situations.

How can I use blockchain technology?
Blockchain is a decentralized, digital ledger for recording and storing data. It is used to verify transactions through consensus. The technology was originally designed for cryptocurrency bitcoin, but it can be applied to other industries too. There are three main ways blockchain can be utilized: as a public record of transactions, as a currency exchange and as an electronic payment system. The first and most widely known use of blockchain is as a public ledger for Bitcoin transactions. Every time there's a transaction involving Bitcoin, that information gets recorded on the block. That block gets encrypted, written onto the chain with other blocks from around the same time period. Since every block contains information about all Bitcoin transactions from when it was created (in this case 2009), we know who owns how many bitcoins at any given point in time just by looking at that one block on the chain. The second way people have started using blockchain is as a currency exchange or transfer. It uses cryptography to allow for secure, anonymous transfers of funds. One company already doing this successfully is Ripple, which uses blockchain to facilitate instant cross-border payments without needing expensive wire transfers or foreign exchanges. The third way people are using blockchain is as an electronic payment system. Online retailer Overstock was the first major retailer to accept Bitcoin back in 2014 and since then dozens more have joined them. Instead of having someone manually process each purchase made online, these retailers accept Bitcoins via their own software systems and immediately convert them into cash.
