When people hear the word “blockchain,” they usually think of cryptocurrency. But here’s the twist—blockchain is way bigger than digital coins. Think of blockchain as the internet of trust. It’s quietly transforming industries, solving problems we didn’t even realize had solutions.
What Is Blockchain in Simple Terms
At its core, blockchain is a shared digital record book. Once something is written into it, it can’t be changed or deleted easily. Every participant gets a copy, making cheating extremely difficult.
