Blockchain is one of the most talked-about technologies of the 21st century—but what is it, really?
In simple terms, blockchain is a digital ledger that stores data in a decentralized, tamper-proof way. Instead of a single central authority, data is spread across a network of computers (called nodes), making it nearly impossible to hack or alter without consensus.
🔍 Why It Matters:
- Transparency: Everyone on the network can view transactions.
- Security: Data is cryptographically protected.
- Decentralization: No middlemen, no gatekeepers.
From powering cryptocurrencies like Bitcoin to enabling smart contracts on Ethereum, blockchain is transforming everything from finance to supply chains.
