Blockchain in simple terms
Cryptocurrency often gets a bad rap, with some people dismissing it outright as a scam. However, when you start digging into this topic, you’re confronted with a barrage of technical terms and concepts that can be daunting. Let’s break down the core benefits of blockchain technology in a way that’s much easier to digest.
Understanding Blockchain
Imagine blockchain as a database designed to store information permanently and securely, following a specific set of rules. This information is updated in real-time and is accessible from anywhere in the world with internet access. Powering this service is a network of computers spread across the globe, managed by a mix of individuals and organizations, thus removing any single point of failure. This network of computers is what makes blockchain decentralized.
Why Is Blockchain Significant?
Consider this scenario: your laptop, which holds all your precious wedding photos and videos, gets stolen. Gone forever, right? Well, you’d reach out to friends or family to send you their copies. This replicates what happens in blockchain — computers around the world have synchronized copies of data, ensuring there’s always a backup available.
You might wonder why not just store everything on iCloud or Google Drive? In the incredibly rare event that tech giants like Apple or Google go under, unless you’ve made backups, your data would vanish with them. Admittedly, these might not seem like compelling reasons to switch to blockchain.
But let’s talk about something more relatable. Imagine hearing news that your bank is facing financial trouble, leading to a run on the bank. When you attempt to withdraw your funds, you discover that withdrawals are frozen. It’s an injustice, isn’t it? Those are your life savings, yet they’re inaccessible due to the bank’s mismanagement. With blockchain, this concern disappears. In the world of blockchain, you essentially become your own bank, for better or for worse. This is part of what’s known as Data Ownership.
What Is Data Ownership in Blockchain?
Ownership of data means you call the shots about when and where to move your data or digital assets. Blockchain enables this through mathematics, specifically cryptography.

Cryptography is akin to writing a secret note with invisible ink that only shows up under UV light. If you don’t know about the light or don’t possess one, the message stays hidden from your eyes.
Enabling Digital Ownership
Digital ownership is granted through asymmetric encryption, which involves a pair of mathematical keys: one for encryption (the secret ink) and one for decryption (the UV flashlight). The public key can be shared openly, much like a bank account number, while the private key is akin to your bank’s master password, critical for carrying out transactions. If someone obtains your private key, they can take control of your assets without any additional verification. You prove you own the data by demonstrating you have the right private key.
How Does Blockchain Benefit Me?
Now, you might be thinking this all sounds risky and complex. What’s the point? Beyond jests about buying cryptocurrency to afford luxury cars, the real value lies in preserving the digital value derived from your time and energy.
Picture this scenario: You play a mobile racing game and gather in-game currency for car upgrades. Then a new fantasy RPG launches. You can convert your racing game currency directly into the new game’s currency and start playing immediately. As you progress, you earn valuable in-game items like in-game gold. Then, say you need to fly to a wedding in Bali. You can sell the in-game gold for hypothetical ‘airline coins,’ which count as a flight discount.
Some might argue you could simply sell in-game currency for USD and buy tickets directly. Yet, most businesses operate in silos with private data systems. If more businesses incorporated blockchain, allowing them to connect parts of their operations, like customer point tallies, the benefits for both users and businesses could be significant.
We haven’t quite reached the seamless interaction I’ve portrayed, but with each technological iteration, we’re moving closer.
In essence, blockchain is a globally distributed database with distinctive mathematical and cryptographic features that enable the transfer of digital assets without the need for intermediaries such as companies or agencies.
