What is Blockchain Technology and How Does it Work?


The rise of the internet and the World Wide Web has been one of the most revolutionary and influential events in modern history. Today, almost every aspect of our daily lives is mediated through digital channels. From online stores to online dating services, almost everything now exists as a result of being digitized and linked together via the internet. Blockchain technology is an important piece of this digital transformation. It’s become popular in recent years for its alleged ability to make transactions faster, safer and more traceable than ever before. In this blog post, we’ll explain what blockchain is, its benefits, types and use cases. We’ll also explore why you should care about blockchain technology today — and what you can do to learn more about it so that you too can begin playing a role in reshaping the way the world works on a global scale.



What is blockchain technology?

The blockchain is a decentralized, digital ledger that records transactions across a peer-to-peer network. The blockchain’s data structure and cryptography control the tightness with which transactions can’t be altered. Because it’s decentralized and distributed, users can verify and audit transactions without having to rely on a centralized authority like a bank or a government to do so. Instead, the verified and verified-not-yet ledger entries are stored in a decentralized network that’s decentralized and distributed across the globe. The entire network works as a single source of truth, which is why it’s also been dubbed a “trustworthy digital ledger.”


How does Blockchain work?

In order to implement blockchain technology, financial institutions have been building “blockchain-as-a-service” (BaaS) offerings. These platforms have become increasingly popular in the financial services industry as a way to speed up transactions and provide more transparency in the financial sector. A blockchain-based digital trading platform is one example of a BaaS. Other industries have created decentralized and distributed apps (dApps) on top of blockchain, such as the food chain traceability app “Eater Chain.”


Types of Blockchain Technology

There are a number of different types of blockchain technology, each with unique benefits and shortcomings. Here are some of the main categories: 

  • Finance Blockchains: Used to conduct trading and settle payment transactions.
  • Human-readable: Most finance-focused blockchain projects rely on fonts and symbols designed for human readers. This makes it much more difficult for businesses to adopt, since they need to be able to read and understand the blockchain content in order to take proper actions on it. 
  • Decentralized: All transactions are confirmed and recorded on a decentralized, peer-to-peer network without a central authority like a bank or a government being involved.


Use Case for Blockchain Technology

Blockchain technology has seen a surge in popularity in the past year or so due to its potential to make transactions faster, safer, and more traceable than ever before. This has led to a lot of hype and media coverage, which sometimes results in confusion about what blockchain actually is, how it works and what benefit it provides. But regardless of all that, the use case for blockchain technology is pretty straightforward. 


It relays financial data, like stock trades and bank account movement, through a decentralized network, removing the need for intermediaries like banks and tax collectors. The decentralized nature of blockchain technology means that no single entity — be it a bank or a business — has control over the information. This makes it susceptible to hacking and other kinds of malicious attacks, which are why it’s crucial to use strong encryption protocols to protect your data. 


Blockchain technology can also be used to record and authenticate consumer purchases, like in a retail store. This kind of functionality can be particularly helpful for places that don’t easily have a banking infrastructure in place — like, say, a small town in Africa or remote islands in the Pacific.



Blockchain technology is a revolutionary idea that has the potential to completely transform how our financial system works. It promises to make international payments more traceable, faster, and cheaper than ever before. The technology has been around for a while, but it’s experienced a surge in popularity in the past year or so due to its potential to make transactions faster, safer, and more traceable than ever before. The use case for blockchain technology is pretty straightforward. It’s used to record and verify financial transactions, like stock trades and bank account movements.
