Step-by-Step: How Blockchain Actually Works
1. Think of it as a Digital Ledger -
Just like a notebook where you write transactions (e.g., "Sanket sent 0.5 BTC to friend"). But this notebook is shared with thousands of computers worldwide.
2. Blocks = Pages of the Notebook -
Every 10 minutes (in Bitcoin), new transactions are grouped into a "block" (like one page).
3. Each Block is Linked (The Magic Chain) -
Every new block contains a special code (hash) of the previous block.
→ Change anything in an old block? The entire chain breaks!
This makes blockchain immutable (unchangeable) and super secure.
4. Decentralized – No Single Boss -
No bank or company controls it. Thousands of computers (nodes) verify everything together. That's why it's called "trustless" – you don't need to trust one person.
Real Example: When you send
$ETH , the transaction goes into a block → gets verified → added to the chain forever. Done!
Even in today's market (BTC stabilizing around $68,000, ETH ~$1,980, SOL ~$86), understanding blockchain helps you see why this technology is so powerful and why big institutions are investing in it.
Got it? Or still have questions about blocks, hashing, or how it connects to Bitcoin/Ethereum?
