What is Blockchain?
Blockchain is a digital ledger — think of it as a record book that everyone can see, but no one can change.
Instead of being stored in one place, its data is spread across thousands of computers around the world.
Each block contains a list of transactions, and once it’s full, it links to the previous one, forming a chain.
This makes blockchain secure, transparent, and nearly impossible to hack.
It’s the technology behind Bitcoin and many other cryptocurrencies — but its uses go far beyond money.
From supply chains to healthcare, blockchain is shaping the future of how we store and share information.
