I’m sure most of you have heard of blockchain, but if I asked, ‘What is blockchain?’ you would probably be unclear about how to answer the question. In this article, I won’t delve into the technical nuances of blockchain; instead, I’ll provide a high-level explanation with examples to ensure you understand what it is and isn’t. Let’s begin our journey!
According to Wikipedia, “a blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes.” Complicated, right? 🤨 Let’s take a simpler approach to understanding it.
Firstly, a blockchain is software that follows rules coded by developers, just like any other software.
To give another perspective, you can also think of blockchain as a notebook. This notebook consists of pages in slightly varying colors that together form a distinct pattern. When you interact with the blockchain, it’s like writing on one of these pages. If someone rips out a page, the pattern is disrupted, making the tampering noticeable. This feature is what makes the blockchain trustworthy, ensuring that applications running on it execute exactly as coded.

Now let’s talk about what blockchain is not. Blockchain is neither a currency nor a bank. It’s a technology with almost unlimited use cases, from tracking your Amazon shipment to allowing data ownership and enabling cheap cross-border payments.
So, the next time someone asks you, ‘What is blockchain?’ you can easily answer the question or just refer them to this article 😉.
